One of my earliest memories of industry as a small boy is actually

0:00:040:00:08

coming along this very canal when I were about seven or eight, with my father, on a bicycle.

0:00:080:00:15

Now, I've never been able to swim, you know, I used to ride along the

0:00:150:00:18

edge of this here tow path or the actual curve on the edge

0:00:180:00:23

and it's a wonder I never fell in, you know.

0:00:230:00:25

And it were a strange place, you know, it's amazing that's really its survived all the, you know...

0:00:250:00:30

50 years, it's still here and all.

0:00:300:00:35

The thing is it were like a time warp, you know?

0:00:350:00:38

There were the remains of old workings,

0:00:380:00:40

wooden pit head gears, and bits of old jib cranes that had all fallen down.

0:00:400:00:45

And it were all very sad in a way, you know, but it never left me mind,

0:00:450:00:49

you know, it got me my first interest in industry going in a way.

0:00:490:00:53

The Industrial Revolution was a time when Britain invented machines that were to change the world.

0:01:150:01:21

It was one of the most important periods in our history,

0:01:210:01:24

but Fred felt it had never really had the attention it deserved.

0:01:240:01:28

Fred was very passionate about engineers and machinery from the past;

0:01:310:01:37

it was a love affair with Fred.

0:01:370:01:39

When I first came here Fred showed me all round the

0:01:390:01:42

garden and explained all about the machines here,

0:01:420:01:45

all the steam engines, and he was like somebody who was explaining like a proud father would about a child.

0:01:450:01:52

What each little item of machinery consisted of, what it did, how it had been made.

0:01:520:02:00

A lot of it went over my head a lot of it was technical and I couldn't

0:02:000:02:04

understand what he was saying,

0:02:040:02:05

but the passion was there...

0:02:050:02:07

and I think most people tapped into that passion, he was able to communicate that very well.

0:02:070:02:13

Through this passion for Britain's industrial past and the machines of a bygone age,

0:02:150:02:20

Fred reminded us of a time when Britain led the world.

0:02:200:02:23

Between 1710 and 1712,

0:02:250:02:29

Thomas Newcomen invented a brand new type of steam engine, the atmospheric engine,

0:02:290:02:36

which was designed solely for one purpose, to pump water from deep mine shafts.

0:02:360:02:41

The first one was installed here in Staffordshire at a colliery

0:02:430:02:46

and it proved to be the world's most successful steam engine.

0:02:460:02:51

Of course, it were used near here at Dudley Castle for

0:02:510:02:54

pumping water out of the many coal mines that were in the area.

0:02:540:02:58

There's very few Newcomen and pumping engines left, and here

0:03:010:03:05

at the Black Country Living Museum they've built a full-size replica

0:03:050:03:09

with a beautiful engine house.

0:03:090:03:11

When it's actually in motion you can, like, step back in time to 1712.

0:03:110:03:18

On the end of the beam, of course, you can see the pump rod which disappears down the mine shaft

0:03:180:03:23

to the pumps in the sump at the bottom.

0:03:230:03:25

This, of course, forces up the water up the rising main and...

0:03:250:03:30

and they let it run away wherever they can.

0:03:300:03:32

For a long time, never understood why,

0:03:340:03:36

people didn't really appreciate Britain's industrial heritage.

0:03:360:03:40

And I suppose it started 40 or even 50 years ago in places like this and Beamish and Ironbridge,

0:03:400:03:45

began to get an interest in it but it needed popularising.

0:03:450:03:48

One of the things that Fred did was bring it to the TV audience,

0:03:480:03:51

which increased it hugely and got more and more people interested.

0:03:510:03:56

-We've got to be very grateful for all he did there.

-Hello, Roger.

0:03:560:04:00

You all right?

0:04:000:04:02

-Yeah. Not so bad, thanks, Fred.

-Yeah, this is Roger who is the chief engineer of this wonderful creation.

0:04:020:04:08

He's going to tell me how it works, he's one of the few men who actually knows how it works.

0:04:080:04:13

Shall I stop it, while we're talking?

0:04:130:04:15

-Is that the brake?

-That's a bit of string and the nail!

0:04:200:04:23

You don't seem to turn any taps off, do you...

0:04:230:04:26

-to stop the thing?

-Well, we've got a very simple boiler.

0:04:260:04:29

When Newcomen conceived of this engine, there was no boiler technology,

0:04:290:04:34

the only thing there was was like a giant kettle from the brewing industry and that's what this is.

0:04:340:04:39

The original had a copper bottom and a lead top, which occasionally would melt,

0:04:390:04:44

and the cylinder is mounted directly above that with a valve.

0:04:440:04:48

It's quite simple, really, isn't it, how it works?

0:04:480:04:51

It is simple, but it's a very, very difficult engine to keep running.

0:04:510:04:55

Most of the work is in keeping the fire right,

0:04:550:04:58

as you say, no valves or anything, so, if the fire's wrong, it just stops and it'll stop very quickly.

0:04:580:05:03

Industrial history had got...

0:05:030:05:05

almost a little bit, sort of academic, in some ways.

0:05:050:05:09

It had started off with volunteers and then had become a little more professional, a little more academic

0:05:090:05:16

and I think Fred's programmes have actually brought the whole thing back more into the public realm

0:05:160:05:23

and allowed just the normal person to become...

0:05:230:05:26

to feel they are able to get more involved in industrial history.

0:05:260:05:30

Well, Roger is now going to activate the engine. Aren't you, Roger?

0:05:300:05:34

-That's what it's all about.

-Yeah.

0:05:340:05:37

In real way, in 1712, this were the cutting edge of technology you know, before then...

0:05:370:05:45

Shall we carry on?

0:05:530:05:56

I hope you got that.

0:05:560:05:58

Fred had a real talent for raising awareness in the areas that he personally was interested in,

0:05:580:06:05

Great at telling stories and great at condensing

0:06:050:06:11

the years of politics and finance and engineering and technology

0:06:110:06:19

into a digestible story.

0:06:190:06:22

A good example of this is the way Fred tells the story of Richard Trevithick

0:06:220:06:26

and the early development of the steam engine in Cornwall.

0:06:260:06:29

Richard Trevithick was a brilliant engineer and inventor and he never really got true

0:06:320:06:37

recognition for his contribution to the development of the steam engine.

0:06:370:06:42

He was a larger than life character who, sort of, were famed for his bare knuckle fighting

0:06:420:06:48

and he had this wonderful ability to solve problems that

0:06:480:06:51

perplexed better engineers, more well-educated engineers like...

0:06:510:06:56

A bit like me, sort of semi illiterate, but yet

0:06:560:06:59

he had this brilliant touch of solving these unbelievable problems.

0:06:590:07:04

He made a fortune and lost a fortune, he went off to South America to the silver mines there

0:07:040:07:10

and came back a, sort of, broken man, you know?

0:07:100:07:13

The thing is that, after all them important things that he did for the

0:07:130:07:18

development of the steam engine, you know, he died a pauper and nobody really knows where he's buried.

0:07:180:07:23

I think industrial history and the whole

0:07:230:07:27

understanding of our industrial past is a bit of a Cinderella in historical terms

0:07:270:07:33

and people have

0:07:330:07:34

tended to go for... for kings and queens and high flown lives and people in very fancy costumes

0:07:340:07:42

but actually I think Fred helped people to understand that there is

0:07:420:07:48

something very special, very heroic about the Industrial Revolution

0:07:480:07:53

and about the...

0:07:530:07:55

lives that it influenced and about the things and places that it produced.

0:07:550:08:02

Trevithick was born at Ilogan, near Cambourne,

0:08:040:08:08

but his family soon moved to this cottage here, nearby, and his father

0:08:080:08:12

was the manager of the Wheel Chance Copper Mine.

0:08:120:08:15

He spent his childhood here and went to the village school, but the headmaster's

0:08:150:08:20

description of him were, "He's a loafer and inattentive and...

0:08:200:08:24

"and, sort of, very slow."

0:08:240:08:27

He spent his time wandering round looking at the tin mines and the machinery that existed at the time.

0:08:270:08:32

He amazed his superiors and so-called men of better education by his unbelievable ability

0:08:320:08:39

for solving mechanical problems without the aid of arithmetic.

0:08:390:08:43

Just by his own intuition, you know?

0:08:430:08:45

You felt that he knew more than you did but not much, that he'd discovered it minutes

0:08:450:08:50

before you switched on your TV and he couldn't wait to tell you about it.

0:08:500:08:54

Trevithick's use of strong steam meant that you could build an engine that weighed ten tons

0:08:540:09:00

that would do the same work as an engine that weighed 650 tons.

0:09:000:09:04

All of Trevithick's early engines were designed to run along the road, you know, and here at Cambourne

0:09:040:09:11

they built a reproduction of the Puffing Devil, which is a quite interesting piece of machinery.

0:09:110:09:18

And the lads on top here are...

0:09:180:09:20

one of them is going to tell me how it all works and all about it.

0:09:200:09:23

So much unlike... sort of, slick television presenters, which I thought was great.

0:09:330:09:40

I mean, I don't... not many TV presenters

0:09:400:09:42

wear overalls and mean it, if you see what I mean, or cloth caps.

0:09:420:09:45

They'd wear it because their stylist told them to.

0:09:450:09:49

And... and... but that wasn't the case with Fred at all.

0:09:490:09:53

You knew he was wearing a cloth cap for real, which was fantastic.

0:09:530:09:57

Passion and enthusiasm are hugely important in trying to get people involved in their heritage.

0:10:090:10:15

I think that Fred did a great deal,

0:10:150:10:16

especially in industrial heritage, which has been an area, although it's been expanding

0:10:160:10:21

over the years, that has very much been misunderstood by many people.

0:10:210:10:26

Whilst he was working as the engineer at the wonderfully named

0:10:280:10:31

Ding Dong Mine in Penzance - super name that, innit?

0:10:310:10:35

He developed his first high pressure engine which,

0:10:350:10:39

of course, led to these great monsters like this one here at Cornish mines.

0:10:390:10:44

You know, I mean, this is a super engine, innit, biggest one I've ever seen.

0:10:440:10:48

The advances Trevithick made in pumping engines and winding engines

0:10:480:10:54

definitely gave Cornwall an unbelievable prosperity

0:10:540:11:00

in between about 1800 and 1870.

0:11:000:11:03

Another great idea that Richard Trevithick came up with was the

0:11:030:11:07

chimney, of course, which improved the draught

0:11:070:11:10

on the boilers and eventually became quite common in, all industrial areas, on the skyline.

0:11:100:11:16

The engineers and manufacturers of Cornwall started to build their own engines, their own pumping engines,

0:11:160:11:23

like the Allman Brothers and Harveys,

0:11:230:11:25

eventually became world famous in the field of pumping engines.

0:11:250:11:31

This behind me is the mine at Lavant and it went more than 1,800 feet down

0:11:310:11:36

and then more than a mile under the Atlantic Ocean towards America.

0:11:360:11:40

Quite an incredible feat... If you look down into this great chasm

0:11:410:11:46

you can see various flights of stone steps coming up the cliffside.

0:11:460:11:52

Now, in the olden days, before the days of steam winders and wire ropes and cages,

0:11:520:11:57

the miners had to get down the face of the cliff,

0:11:570:11:59

far down nearer to the sea as they could, and then enter by an "addit" that met the main shaft going down,

0:11:590:12:05

then continue the journey for 1,800 feet on ladders with various platforms down the shaft.

0:12:050:12:12

And then, of course, they'd got to go for a mile underneath the ocean before they actually started work,

0:12:120:12:18

you know? They must have been some special men.

0:12:180:12:20

This engine here were what were known as the fast winder

0:12:220:12:26

and, of course, it's based on a James Watt beam engine principle,

0:12:260:12:31

but it were built by Harveys of Hale in 1840.

0:12:310:12:34

And it wound skips of ore from a shaft 1,800 feet deep in five minutes.

0:12:340:12:39

-Right, Dick, are you going to let me have a go?

-Yeah, certainly.

0:12:410:12:44

-What's first job? Take the brake off?

-Yeah.

0:12:440:12:47

Right. How many times?

0:12:470:12:48

Wait a minute.

0:12:480:12:51

-Is that enough?

-It's OK.

0:12:510:12:52

-Give her a bit of steam.

-Yeah, about there.

0:12:520:12:55

-Ah, wonderful.

-I think Fred's contribution was enormous because his

0:13:000:13:03

passion and interest wasn't for a single subject or a single machine.

0:13:030:13:08

It was... his passion was for steam engines in their context.

0:13:080:13:11

Whether it was on railways or in factories, it didn't really matter,

0:13:110:13:14

so I think his programmes had such a wide appeal

0:13:140:13:18

because it wasn't just one machine after another, it was looking at places and people.

0:13:180:13:23

Yeah, of course.

0:13:230:13:25

Up there you can see the great beam racking up and down.

0:13:250:13:28

The thing is, it's a bit unusual because the

0:13:280:13:30

pumping engines have half the beam sticking outside into space.

0:13:300:13:35

This one's all inside the engine house.

0:13:350:13:38

A bit different. I suppose the man who did the winding would be here all day, you know,

0:13:380:13:43

he wouldn't like ocean and the wind blowing.

0:13:430:13:45

Down below there, that's the condenser, which,

0:13:480:13:50

of course, makes the vacuum to make the piston go up and down a lot easier.

0:13:500:13:56

You know, with... is approximately 14 pounds

0:13:560:14:00

per square inch less pressure, you know, against the steam, you know,

0:14:000:14:05

that makes it much more economical.

0:14:050:14:07

That's why Cornish steam engines very economical.

0:14:070:14:12

It'd be a feat of engineering just getting the engineer

0:14:130:14:16

on the edge of this great plate.

0:14:160:14:18

-Yeah, yeah.

-Yeah.

-No heavy lifting gear or anything like that.

-No, no.

0:14:180:14:23

I think Fred had really quite a big influence in popularising

0:14:230:14:28

the Industrial Revolution and the history of machinery.

0:14:280:14:35

Fred obviously has a passion for machinery and that, I think, comes over in every programme.

0:14:350:14:41

And he particularly loved the golden age of engineering, the golden age of mechanical engineering.

0:14:410:14:48

I mean, in the 1700s and before that, machinery

0:14:480:14:52

is stuff that people have to work quite hard to make work at all

0:14:520:14:56

so it tends to be iron and black and with big pieces of wood in it.

0:14:560:15:01

In spite of Newcomben's unbelievable success and the worldwide acclaim for these engines,

0:15:010:15:07

they had a lot of weak points, you know? Like this particular bit here

0:15:070:15:10

is the injection cock for condensing the steam inside the cylinder,

0:15:100:15:15

and, of course, what happened were every time, every stroke,

0:15:150:15:19

the cold water going in cooled off all the cylinder,

0:15:190:15:22

so part of the next lot of steam had to warm it all up again, you know?

0:15:220:15:26

It were all right if you had lots of fuel, but places like Cornwall

0:15:260:15:30

where, you know, they've got to bring it a long way...

0:15:300:15:33

It's reputed that there were one company in Cornwall that actually owned a thousand horses

0:15:330:15:38

to get the coal from the sea what had come from South Wales down into where the tin mines were.

0:15:380:15:45

And, of course, reputed to burn as much as 12 tons of coal in a day, you know?

0:15:450:15:51

So when you took it away from the coalfields it weren't very efficient at all.

0:15:510:15:55

And they were also quite dangerous, like the type of boiler they had

0:15:550:15:59

were a pretty flimsy affair, you know?

0:15:590:16:02

Some of them were of iron plate, some of them top part were lead,

0:16:020:16:06

and, of course, it's not noted for its great strength

0:16:060:16:09

and, of course, there were frequent explosions even though they only used very low pressures, you know?

0:16:090:16:14

The only pressure they needed were a few pounds to make the thing work.

0:16:140:16:18

The other thing, of course, that were wrong with it in a way were,

0:16:200:16:24

it only produced a reciprocating motion, which means up and down,

0:16:240:16:29

which meant it could only be used really for pumping coal mine shafts out, getting the water up.

0:16:290:16:36

What really were needed were a few improvements in it

0:16:360:16:38

and some form of turning it into a rotary machine, you know,

0:16:380:16:43

that could drive the new machines in textile mills and iron workses

0:16:430:16:48

that were springing up all over the place at this period in our history.

0:16:480:16:53

By the early 1800s and through to the early 1900s, that's the golden age of mechanical engineering.

0:16:530:17:00

Those very, very beautiful machines which you can see running,

0:17:000:17:04

and you can just look at them and they are, sort of, logic expressed in metal.

0:17:040:17:08

That golden age of mechanical engineering, Fred really helped to bring that to life for people.

0:17:080:17:14

Because the Industrial Revolution really is the only time

0:17:140:17:18

when this island has been centre stage in terms of world history.

0:17:180:17:22

This is the time when Britain led the world - it's its big contribution to the world, really.

0:17:220:17:28

Reputedly, the man who decided to connect the cylinder up to the crank shaft is Richard Trevithick.

0:17:550:18:01

Along with a gentleman in Leeds called Matthew Murray,

0:18:010:18:05

they developed the horizontal type of engine,

0:18:050:18:08

and there were literally thousands of engines like this made, from little teeny ones three foot long,

0:18:080:18:15

to the biggest one on record were made by a company in Bolton called Nick Hargreaves's,

0:18:150:18:20

and reputedly the cylinder were ten feet long.

0:18:200:18:24

It had ten foot stroke on it, you know, an incredible machine, you know, and all.

0:18:240:18:29

I don't know how many hundred horsepower, but it's supposed to be

0:18:290:18:32

the biggest single cylinder horizontal steam engine ever made.

0:18:320:18:36

I've got some drawings of it in a book at home.

0:18:360:18:39

You've only got to look at some of the work that Fred did

0:18:390:18:44

when he's looking at some of the great mill engines or the like

0:18:440:18:47

and going almost overboard about them, to realise that

0:18:470:18:51

he appreciated the skill and quality that went into them

0:18:510:18:55

and that that comes over and people stop to think about it.

0:18:550:18:58

Not everything the Victorians did was great or good quality by any means,

0:18:580:19:03

but he tended to pick the really good things and put over exactly how important it was to get things right.

0:19:030:19:08

The horizontal steam engine was much easier to manufacture in all sizes and, sort of,

0:19:080:19:16

you didn't have to have a great big tall engine room to keep it in.

0:19:160:19:21

And so they made hundreds and hundreds of them, everywhere.

0:19:210:19:25

Really, to build an engine like this all as you needed were a big lathe, a shaper and a good iron founder,

0:19:250:19:31

and you could make one in a shed. I've more or less done it myself once or twice.

0:19:310:19:36

Industrial history and industrial archaeology is a relatively new area

0:19:360:19:40

and is greatly misunderstood by many people.

0:19:400:19:43

They see a...like a load of angle iron rusting away in a corner, not realising the importance of that.

0:19:430:19:49

And so, through bringing it to television and bringing it to life,

0:19:490:19:52

Fred has been hugely important in making people, the wider population,

0:19:520:19:56

understand the importance of our industrial heritage.

0:19:560:19:59

Britain's industrial heritage is absolutely unique.

0:19:590:20:02

The birthplace of the Industrial Revolution, this is where it all started.

0:20:020:20:06

We can't lose these wonderful buildings and wonderful monuments

0:20:060:20:09

to that age of utter ingenuity and great, great expansion.

0:20:090:20:15

So Fred has been extremely important in putting that on television

0:20:150:20:18

and getting people, and therefore getting politicians,

0:20:180:20:22

the ones who have the power of life and death over these great monuments, to understand what it's all about.

0:20:220:20:27

Steam power didn't really cause the Industrial Revolution

0:20:280:20:33

but it played a very important part in it.

0:20:330:20:36

The factory system, of course, were developed from the textile industry

0:20:360:20:41

and, of course, all this were done a long time before the steam engine became fully developed.

0:20:410:20:47

Quarry Bank Mill at Styal is hidden away behind Manchester Airport

0:20:480:20:53

and it is, without a doubt, one of the very best places

0:20:530:20:57

where you can see the steam engine and water power working together.

0:20:570:21:02

The original water wheel was designed and built by

0:21:020:21:05

Sir William Fairburn of Manchester who were very famous for his...

0:21:050:21:09

what they call suspension water wheels which, of course,

0:21:090:21:13

I think comes from the fact that they'd put the first segment in the bottom of the water wheel pit

0:21:130:21:18

and anchor it to the spokes so it'd be suspended,

0:21:180:21:22

move it round one and put another in, move it round one and put another in, and it'd end up round.

0:21:220:21:27

The thing is that the original one was so far gone, you know, and rotten...

0:21:270:21:32

they found this one at a place called Pateley Bridge in Yorkshire

0:21:320:21:37

and, of course, they'd obviously done a heck of lot of work on it.

0:21:370:21:40

All the plating is all brand new, you know, the...

0:21:400:21:44

Some of the spokes are original, I think, they're quite rusty.

0:21:440:21:48

When this water wheel were first installed, you know, steam engines were quite well developed

0:21:480:21:54

but they were a bit unreliable, and, of course, this thing runs for nothing, you know?

0:21:540:21:58

And all the trouble with breaking down and bringing coal and all that,

0:21:580:22:01

it still was a formidable source of power, as you can see with the size of it, you know?

0:22:010:22:08

Looking through these reduction gears behind me,

0:22:080:22:11

a lot of power there to drive all the machinery in the mill.

0:22:110:22:15

These things are called looms, spinning properly.

0:22:190:22:23

The noise levels are terrific. Can you imagine what it must have been like with...

0:22:230:22:29

in a room with 1,500 of these things, all going at the same time

0:22:290:22:35

for 16 hours a day, you know?

0:22:350:22:38

Could see why it's all faded away. No wonder they were all deaf.

0:22:380:22:43

He could be your mate. You'd want to sit in a pub

0:22:430:22:47

drinking with Fred and listening to his tales,

0:22:470:22:51

and I think that's what... that was one of Fred's best points.

0:22:510:22:55

You could relate to him, he was a typical working man

0:22:550:22:59

and yet he'd got this fascination for the subject that he loved so much

0:22:590:23:03

and that really came over, and I think that's how people have become more interested in it.

0:23:030:23:09

Even today, the weaving shed takes its power from the water wheel, you know?

0:23:090:23:15

And this is part of the transmission,

0:23:150:23:17

this great vertical shaft that comes through three floors,

0:23:170:23:21

up to this level where the weaving shed is.

0:23:210:23:24

And, of course, the beveled gears and then the horizontal shaft

0:23:240:23:27

and then the counter shafts and then the looms proper,

0:23:270:23:29

well these things were always a great source of trouble.

0:23:290:23:32

The great weight of a vertical shaft, especially in a spinning mill

0:23:320:23:36

which nearly always were four and five storeys high,

0:23:360:23:40

they always got hot at the bottom and, of course, once it got hot, the whole mill had to stop.

0:23:400:23:45

He's put engineering history onto a higher plane than it was before,

0:23:450:23:50

and there must be many museums around the country that are grateful for it.

0:23:500:23:55

As to... As to people's understanding of engineering, I think that was also helped.

0:23:550:24:03

He was so careful to actually show you something and how something operated or how it was built.

0:24:030:24:09

Basically, the transmission, you know, into the...

0:24:090:24:12

from the water wheel comes up the shaft, up the vertical shaft.

0:24:120:24:16

Then, of course, it's transmitted into these long ones which are called line shafts.

0:24:160:24:22

In reality, these are not very long, you know?

0:24:220:24:26

I mean, some of them in olden days, when the torque started at one end

0:24:260:24:30

the other end didn't move for a bit til they'd twisted the shaft.

0:24:300:24:34

There were such great weight on them, you know, and they started off at the driven end quite thick,

0:24:340:24:40

and by the time they'd gone the full length of the weaving shed,

0:24:400:24:43

they kept stepping down a bit in diameter, you know, cos of the twisting action.

0:24:430:24:49

Quite an interesting... There's book upon book about mill shaft fixing

0:24:490:24:53

and mill writing that, you know, it became quite an art, you know, setting up line shafts.

0:24:530:24:59

Number one, they've got to be exactly dead straight and level.

0:24:590:25:04

If they're a bit bent, you know, it creates a lot of trouble.

0:25:040:25:08

The great problem with water wheels, they were very economical to run and all of that, like,

0:25:080:25:13

but there were one big problem.

0:25:130:25:16

In times of drought, the work stopped and everybody had to go home.

0:25:160:25:21

Steam power was only introduced, really, to help out the water wheel, you know,

0:25:240:25:29

but forward-thinking mill owners soon realised that it were a better form of power.

0:25:290:25:35

In 1810, the mill owner Samuel Greg

0:25:370:25:40

installed this beam engine, not to be the main source of power,

0:25:400:25:45

but just to help out the water wheel in times of drought and low water.

0:25:450:25:50

James Watt came up with a magnificent idea, you know?

0:25:500:25:54

He separated the condensing department from the cylinder, you know, separate unit altogether.

0:25:540:26:00

What happens in this case is this here is the valve chest, this rectangular shaped iron box,

0:26:000:26:06

this is the exhaust pipe and, when the steam is exhausted from the cylinder through the valve chest,

0:26:060:26:12

it comes down this pipe and goes into the condenser.

0:26:120:26:16

And on the other end of the beam the rod that goes down the well, that's pumping up cold water

0:26:160:26:21

and, of course, that goes through a pipe round the back here

0:26:210:26:24

and into the condenser and condenses the steam, you see, which of course helps the engine, you know?

0:26:240:26:31

The engine is not working against fifteen pounds per square inch of atmosphere, so it runs sweeter.

0:26:310:26:38

It became... The ending didn't just show you what was...

0:26:380:26:42

what was in front of you,

0:26:420:26:44

he would actually explain the pistons, the valves and never was he happier when

0:26:440:26:49

on the top of a beam engine or something like that, looking down.

0:26:490:26:52

Here we can see the beam in all its glory, you know?

0:26:520:26:55

This is, of course, the connected rod end which is connected to the crank shaft.

0:26:550:27:00

This bit here works the water pump that pumps the water, the cold water for the condenser,

0:27:000:27:07

and then, of course, James Watt's biggest and best thing, the parallel motion.

0:27:070:27:13

Watt came up with this wonderful system of levers

0:27:130:27:17

that does away with the arc that the end of the beam would strike -

0:27:170:27:20

if you just connected the connecting rod to the end of the beam,

0:27:200:27:24

at each stroke it would try and bend the connecting rod, which would be terrible for the cylinder and the...

0:27:240:27:30

and the connecting rod itself.

0:27:300:27:34

And this is it, the magical system of levers that keeps the piston rod in a straight line

0:27:340:27:41

while the end of the beam goes up and down.

0:27:410:27:43

Throughout his series, Fred's visited some of these...

0:27:430:27:46

the places that are trying to restore our industrial past.

0:27:460:27:51

And maybe the public didn't realise the work that was going on there.

0:27:510:27:56

When you look at some of the places Fred's visited,

0:27:560:27:59

even us at this site didn't realise that that was happening.

0:27:590:28:04

He really brought it home to people that people are trying to restore,

0:28:060:28:10

and that there are some fascinating things there for people to see.

0:28:100:28:15

The series of programmes that he did on television featured,

0:28:150:28:20

the machines of the Industrial Revolution, basically,

0:28:200:28:24

and our empire was based on that Industrial Revolution.

0:28:240:28:29

We exported engineers to the world and Fred brought that

0:28:290:28:32

back into the public eye through the series of programmes he did.
