STEAM HISSES | 0:00:21 | 0:00:24 | |
This is my back garden. | 0:00:26 | 0:00:29 | |
Everything's driven by steam. I don't need electricity. | 0:00:29 | 0:00:33 | |
The boiler produces the steam to drive three steam engines that work all of my workshop. | 0:00:33 | 0:00:40 | |
But the drawback, as against an electric motor, is the fact | 0:00:40 | 0:00:46 | |
that you can't just press a button and start it off. | 0:00:46 | 0:00:50 | |
It takes me roughly a day to get the whole place going. | 0:00:50 | 0:00:54 | |
With belt-driven machinery, just at the crucial moment, the belt breaks | 0:00:54 | 0:01:00 | |
and the job's stopped - but it's very cheap. | 0:01:00 | 0:01:04 | |
At one time it was all steam engines round here, driving cotton mills, engineering works and the likes. | 0:01:06 | 0:01:13 | |
Now this must be the only steam-powered works in all of Bolton. | 0:01:13 | 0:01:18 | |
For nearly 200 years, steam drove the wheels of industry, making Britain | 0:01:18 | 0:01:25 | |
the greatest industrial nation in the world. | 0:01:25 | 0:01:28 | |
But it hadn't always been the case. | 0:01:28 | 0:01:31 | |
Steam power didn't really cause the Industrial Revolution, | 0:01:31 | 0:01:36 | |
but it played a very important part in it. | 0:01:36 | 0:01:39 | |
The factory system developed from the textile industry | 0:01:39 | 0:01:44 | |
a long time before the steam engine became fully developed. | 0:01:44 | 0:01:48 | |
Quarry Bank Mill at Styal is hidden away behind Manchester Airport. | 0:01:48 | 0:01:54 | |
When the mill was first built, in the latter half of the 18th century, | 0:01:54 | 0:01:59 | |
they used water power to drive the revolutionary spinning machinery. | 0:01:59 | 0:02:04 | |
It is, without a doubt, one of the best places | 0:02:04 | 0:02:07 | |
where you can see steam and water power working together. | 0:02:07 | 0:02:11 | |
The original water wheel was designed and built | 0:02:11 | 0:02:16 | |
by Sir William Fairbairn of Manchester, | 0:02:16 | 0:02:19 | |
who was very famous for his what they call "suspension" water wheels. | 0:02:19 | 0:02:24 | |
They put the first segment in the bottom of the water wheel pit | 0:02:24 | 0:02:29 | |
and anchor it to the spokes so it's suspended, | 0:02:29 | 0:02:32 | |
move it round one and put another in, move it round one and put another in. | 0:02:32 | 0:02:37 | |
Eventually, it would end up round. | 0:02:37 | 0:02:40 | |
When this water wheel was installed, steam engines were well developed. | 0:02:40 | 0:02:45 | |
But they were a bit unreliable. | 0:02:45 | 0:02:48 | |
This thing runs for nothing, with no breakdowns, coal and all that. | 0:02:48 | 0:02:53 | |
It still was a formidable source of power. | 0:02:53 | 0:02:56 | |
You can see, with the size of it, working through these reduction gears, | 0:02:56 | 0:03:02 | |
it could drive all the machinery in the mill. | 0:03:02 | 0:03:06 | |
WATER TRICKLES | 0:03:06 | 0:03:11 | |
Even today, the weaving shed takes its power from the water wheel. | 0:03:11 | 0:03:16 | |
This is part of the transmission. | 0:03:16 | 0:03:19 | |
A great, vertical shaft comes up through three floors to this level, where the weaving shed is. | 0:03:19 | 0:03:26 | |
The bevel gears, the horizontal shaft, then the counter-shafts, and then the looms proper. | 0:03:26 | 0:03:32 | |
These things always caused trouble. | 0:03:32 | 0:03:34 | |
The great weight of a vertical shaft, | 0:03:34 | 0:03:37 | |
especially in spinning mills, which were four and five storeys high... the problem was | 0:03:37 | 0:03:43 | |
getting the weight of each length of the shaft equalised on thrust bearings. | 0:03:43 | 0:03:49 | |
They could never quite get it right and it always got hot at the bottom, and the whole mill had to stop. | 0:03:49 | 0:03:56 | |
Basically, the transmission from the water wheel | 0:03:59 | 0:04:03 | |
comes up the shaft - the vertical shaft - then it's transmitted | 0:04:03 | 0:04:08 | |
into these long ones, which are called wind shafts. | 0:04:08 | 0:04:13 | |
In reality, these are not very long. | 0:04:13 | 0:04:16 | |
When the torque started at one end, the other end didn't move for a bit, | 0:04:16 | 0:04:21 | |
so it actually twisted the shaft, there was such great weight on them. | 0:04:21 | 0:04:26 | |
They started off at the driven end quite thick. By the time they'd gone the full length of the weaving shed, | 0:04:26 | 0:04:33 | |
they kept stepping down a bit in diameter cos of the twisting action. | 0:04:33 | 0:04:39 | |
It became quite an art, setting up wind shafts. | 0:04:39 | 0:04:43 | |
CLACKING These things are called looms, | 0:04:43 | 0:04:47 | |
for spinning cloth with. | 0:04:47 | 0:04:49 | |
The noise levels are terrific. | 0:04:49 | 0:04:52 | |
Can you imagine what it must have been like | 0:04:52 | 0:04:55 | |
in a room with 1,500 of these things | 0:04:55 | 0:04:58 | |
all going at the same time | 0:04:58 | 0:05:01 | |
for 16 hours a day? | 0:05:01 | 0:05:03 | |
CLACKING OF INDIVIDUAL LOOMS ADDS UP TO RHYTHMIC CRASHING | 0:05:06 | 0:05:10 | |
Water wheels were very economical to run and all of that, like, | 0:05:18 | 0:05:22 | |
but there were one big problem. | 0:05:22 | 0:05:25 | |
In times of drought, the work stopped and everybody had to go home. | 0:05:25 | 0:05:30 | |
They had to bring in another way to drive the machines. | 0:05:32 | 0:05:36 | |
Steam power was only introduced, really, to help out the water wheel. | 0:05:36 | 0:05:41 | |
Forward-thinking mill owners soon realised that it were a better form of power. | 0:05:41 | 0:05:48 | |
In 1810, Samuel Greg, the mill owner, | 0:05:48 | 0:05:52 | |
installed a beam engine, | 0:05:52 | 0:05:54 | |
not to be the main source of power but to help the water wheel in a drought. | 0:05:54 | 0:06:00 | |
In 1836, | 0:06:02 | 0:06:04 | |
Mr Greg replaced his original engine | 0:06:04 | 0:06:06 | |
with a Boulton and Watt beam engine of all of 20 horsepower. | 0:06:06 | 0:06:11 | |
By the end of the 18th century, Boulton and Watt | 0:06:11 | 0:06:15 | |
had taken the lead in steam engine technology. | 0:06:15 | 0:06:19 | |
Up to this time, all the early engines, | 0:06:19 | 0:06:22 | |
including Watt's, could only pump water. | 0:06:22 | 0:06:26 | |
But in the 1790s, because of the introduction of machines like these to the textile industries, | 0:06:26 | 0:06:32 | |
a new type of engine was needed to power them. | 0:06:32 | 0:06:36 | |
The early steam engines had been built using quite primitive methods. | 0:06:36 | 0:06:41 | |
The blacksmith had done everything by eye. | 0:06:41 | 0:06:44 | |
But all this was to change. | 0:06:44 | 0:06:47 | |
Boulton and Watt worked everything out in advance with measured drawings, | 0:06:47 | 0:06:53 | |
architectural-style, for all the machines and parts. | 0:06:53 | 0:06:57 | |
It was really the beginning of the engineering industry as we know it. | 0:06:57 | 0:07:03 | |
Birmingham City Libraries have a collection of Watt's papers and drawings, | 0:07:03 | 0:07:09 | |
including some relating to an engine | 0:07:09 | 0:07:12 | |
built for a Manchester cotton mill. | 0:07:12 | 0:07:15 | |
This is an agreement between James Watt and Matthew Boulton and their customer, | 0:07:15 | 0:07:22 | |
Peter Drinkwater, a Manchester cotton mill owner. | 0:07:22 | 0:07:25 | |
While Drinkwater was having the engine built, he obviously decided | 0:07:25 | 0:07:32 | |
he needed more power. He originally asked them to build a 6hp engine. | 0:07:32 | 0:07:37 | |
But he changed his mind, so they had to change the specification to eight horses. | 0:07:37 | 0:07:43 | |
-The change was incorporated into the agreement. -"Eight good horses"! | 0:07:43 | 0:07:49 | |
Not eight weak horses, but eight good horses! | 0:07:49 | 0:07:53 | |
James Watt introduced the term "horsepower" into engineering usage. | 0:07:53 | 0:07:59 | |
Boulton and Watt were very keen to define | 0:07:59 | 0:08:02 | |
exactly what their engines were being used for, so this sets out | 0:08:02 | 0:08:07 | |
that the engine's being used for preparing and carding cotton. | 0:08:07 | 0:08:12 | |
-Drinkwater has to apply to Watt and Boulton for their consent. -Yeah. | 0:08:12 | 0:08:18 | |
-He were pretty strict on all this tackle. -He was. It was all to protect his patent. | 0:08:18 | 0:08:24 | |
This is the actual drawing | 0:08:24 | 0:08:27 | |
for the Drinkwater engine for Manchester. | 0:08:27 | 0:08:32 | |
All the alterations are marked on in red. | 0:08:32 | 0:08:36 | |
The interesting bit is, where they decided to change it from 6hp to 8hp, | 0:08:36 | 0:08:41 | |
-they've put another couple of inches in the diameter of the cylinder. -Yes. | 0:08:41 | 0:08:46 | |
They've crossed out the original 14 inches and increased it to 16. | 0:08:46 | 0:08:52 | |
On the beam, | 0:08:52 | 0:08:54 | |
they specify the wood - "seasoned, straight-grained, young oak". | 0:08:54 | 0:08:59 | |
The spring beams, across the top, are made out of deal, much softer than oak. | 0:08:59 | 0:09:06 | |
The steam engine had arrived and it had a massive impact. | 0:09:06 | 0:09:10 | |
The rapid rise in manufacturing completely altered the whole skyline. | 0:09:12 | 0:09:17 | |
Pithead gears like this one, at Beamish Open Air Museum, sprang up all over the skyline. | 0:09:17 | 0:09:24 | |
It wasn't long before the mine owners realised that, as well as pumping water, | 0:09:24 | 0:09:30 | |
steam engines could be used to lower men down to get to the work quicker, | 0:09:30 | 0:09:34 | |
and, of course, bring up the end product - | 0:09:34 | 0:09:38 | |
cage after cage of coal. | 0:09:38 | 0:09:41 | |
This is one of the earliest types of this winder. | 0:09:52 | 0:09:56 | |
They were quite common in the north-east of England - the vertical steam winding engine - | 0:09:56 | 0:10:03 | |
which, in its time, will have brought up millions of tons of coal | 0:10:03 | 0:10:09 | |
in, no doubt, a cage with two decks and two tubs in each deck. | 0:10:09 | 0:10:14 | |
There'd be five or six hundredweight in each tub every time. | 0:10:14 | 0:10:19 | |
And it would wind the men up and down as well, | 0:10:19 | 0:10:23 | |
but a bit slower than what they wound the coal. | 0:10:23 | 0:10:27 | |
The engine driver here's got to get the coal coming up as fast as he could for the management. | 0:10:27 | 0:10:34 | |
Coal production soared and shafts got deeper, which enabled the manufacturers | 0:10:34 | 0:10:40 | |
to install more steam engines and burn more coal | 0:10:40 | 0:10:44 | |
and it's really what made Great Britain great. | 0:10:44 | 0:10:48 | |
By the middle of the 19th century, | 0:10:51 | 0:10:53 | |
the steam engine had been harnessed to nearly every industry. | 0:10:53 | 0:10:58 | |
It were cheap to run, it made manufacturing much easier | 0:10:58 | 0:11:02 | |
and the Industrial Revolution had arrived. | 0:11:02 | 0:11:06 | |
And it had a massive effect on the lives of ordinary working people. | 0:11:06 | 0:11:11 | |
They began to move from the country to the new industrial cities. | 0:11:11 | 0:11:16 | |
These were springing up close to the coalfields and transport links | 0:11:16 | 0:11:21 | |
that brought raw materials to them. | 0:11:21 | 0:11:24 | |
This is the Etruscan Bone and Flint Mill in Stoke-on-Trent. | 0:11:25 | 0:11:30 | |
You might be wondering what a bone and flint mill is. | 0:11:30 | 0:11:34 | |
Well, crushed bones and flints are ingredients of bone china. | 0:11:34 | 0:11:39 | |
Here in Etruria, it was a centre of crushing bones and flints up | 0:11:39 | 0:11:44 | |
to put fine bone china on the tables of the gentry. | 0:11:44 | 0:11:48 | |
Inside, there's the trusty old beam engine. | 0:11:48 | 0:11:52 | |
This one is a copy of a Boulton and Watt engine | 0:11:52 | 0:11:55 | |
made in Salford in the 1820s. | 0:11:55 | 0:11:58 | |
The drive shaft goes | 0:11:58 | 0:12:00 | |
through a hole in the wall to drive the machines. | 0:12:00 | 0:12:04 | |
This is the other side of the hole in the wall. | 0:12:04 | 0:12:07 | |
It's called the gear room and you can see why, with these cog wheels. | 0:12:07 | 0:12:12 | |
What happens here is it spreads out | 0:12:12 | 0:12:15 | |
the rotary motion of the beam engine into two long, horizontal shafts. | 0:12:15 | 0:12:20 | |
Then, through these big bevel gears, | 0:12:20 | 0:12:23 | |
it drives vertical shafts to the mixing pans upstairs. | 0:12:23 | 0:12:28 | |
The vertical shafts came up from down below in the middle of these great pans | 0:12:28 | 0:12:34 | |
and turned round these big paddles and mixed up the flint and the bone. | 0:12:34 | 0:12:39 | |
Before being put in the pans, they were burned in two kilns downstairs and they added all the lot, | 0:12:39 | 0:12:47 | |
poured in the water and set the thing in motion. | 0:12:47 | 0:12:50 | |
And the stones and the paddles, turning all the lot round, ground it into a beautiful, white, fine slurry. | 0:12:50 | 0:12:57 | |
To make it all work, they had to have an efficient way of raising steam. | 0:12:57 | 0:13:03 | |
This is what's known as a Cornish boiler, | 0:13:05 | 0:13:08 | |
reputedly invented by Richard Trevithick in Cornwall - that's why it's called a Cornish boiler. | 0:13:08 | 0:13:15 | |
Basically, it's quite a simple thing. | 0:13:15 | 0:13:18 | |
It's an iron tube with two end-plates. There's another iron tube, of a smaller diameter, | 0:13:18 | 0:13:25 | |
which is this, termed the fire tube, which goes from one end to the other. | 0:13:25 | 0:13:30 | |
And at the front end of this tube, | 0:13:30 | 0:13:33 | |
a fire is lighted on the grate and the products of combustion | 0:13:33 | 0:13:38 | |
go round the end of the back of the boiler up there and along the sides, | 0:13:38 | 0:13:44 | |
and, finally, up the chimney. | 0:13:44 | 0:13:46 | |
They utilise as much of the heat as they can from the products of combustion. | 0:13:46 | 0:13:51 | |
They only have a fire in here a few times a year. | 0:13:51 | 0:13:55 | |
But, at home, I've got steam up most of the time. It's important to know | 0:13:55 | 0:14:00 | |
where the water level is. | 0:14:00 | 0:14:02 | |
This is the water gauge. When you open the valve, | 0:14:02 | 0:14:07 | |
the steam pressure inside fires the water down. | 0:14:07 | 0:14:11 | |
When you shut the valve, it's forced in at the bottom | 0:14:11 | 0:14:16 | |
by the water pressure and you can see it rise up again. | 0:14:16 | 0:14:19 | |
A bit higher up is the pressure gauge, | 0:14:19 | 0:14:22 | |
a clock with a steel, spiral tube inside it. | 0:14:22 | 0:14:26 | |
When it gets up to pressure, or its pressure's rising, | 0:14:26 | 0:14:30 | |
it works a quadrant and a rack | 0:14:30 | 0:14:33 | |
and it registers on a needle the pounds upon the square inch that's in the boiler. | 0:14:33 | 0:14:39 | |
The steam at the back | 0:14:39 | 0:14:42 | |
is not the boiler leaking - it's the safety valve. | 0:14:42 | 0:14:46 | |
Without that, it would blow up! | 0:14:46 | 0:14:48 | |
People don't realise, really, the power of steam. | 0:14:48 | 0:14:52 | |
This boiler looks peaceful and it's not making any funny noises, | 0:14:52 | 0:14:57 | |
and there's only 75lb per square inch in it. | 0:14:57 | 0:15:01 | |
Other than it being very hot, | 0:15:01 | 0:15:04 | |
it's like a potential bomb, in a way. | 0:15:04 | 0:15:07 | |
This is like a demonstration of what's inside - you know. | 0:15:07 | 0:15:11 | |
ROARING HISS | 0:15:13 | 0:15:15 | |
HISSING CONTINUES | 0:15:18 | 0:15:22 | |
SILENCE | 0:15:23 | 0:15:25 | |
Yeah. | 0:15:25 | 0:15:26 | |
You see - all that pent-up power inside. | 0:15:26 | 0:15:30 | |
Of course, we all know, in the olden days, | 0:15:30 | 0:15:33 | |
there were lots and lots of boiler explosions when things went wrong. | 0:15:33 | 0:15:38 | |
One day, a newspaperman came with his cameraman. | 0:15:38 | 0:15:42 | |
And the cameraman said - he were getting on a bit, the cameraman - | 0:15:42 | 0:15:47 | |
he said, "When I were a lad and I worked for the Chorley Guardian, | 0:15:47 | 0:15:52 | |
"the editor said, 'Go to the weaving shed. There's been an explosion.'" | 0:15:52 | 0:15:57 | |
He said, "I set off with me camera and arrived at this weaving shed, | 0:15:57 | 0:16:01 | |
"to be greeted by an unbelievable scene of carnage and disaster." | 0:16:01 | 0:16:06 | |
In the weaving shed, which was mainly run by women, | 0:16:06 | 0:16:10 | |
all the machinery started going round at 1,000 miles an hour. | 0:16:10 | 0:16:15 | |
The whole works looked like it would fall down. | 0:16:15 | 0:16:19 | |
The governors on the engine had gone wrong. Revolutions built up. | 0:16:19 | 0:16:25 | |
Two of them in the engine room. | 0:16:25 | 0:16:28 | |
One says, "I'll get the women out. You see the engineer about getting the engine stopped." | 0:16:28 | 0:16:34 | |
The guy going to the engine house was halfway across the mill yard | 0:16:34 | 0:16:39 | |
when the whole thing exploded and he ended up dead. | 0:16:39 | 0:16:43 | |
But the man in charge of the engine, who was turning the stop valve off, | 0:16:43 | 0:16:48 | |
had just got it shut when the whole thing blew apart and all it did was break his arm - he survived. | 0:16:48 | 0:16:55 | |
But bits of the engine were going | 0:16:55 | 0:16:58 | |
through Coronation Street-type rooftops 500 yards down the road. | 0:16:58 | 0:17:03 | |
And that were quite late on - 1956, or something like that. | 0:17:03 | 0:17:08 | |
But in spite of the dangers, it was still a very efficient way of driving the wheels of industry, | 0:17:08 | 0:17:16 | |
especially as steam engine technology moved on. | 0:17:16 | 0:17:20 | |
By the mid-19th century, Boulton and Watt's rotating beam engine began to give way to this thing - | 0:17:20 | 0:17:27 | |
the horizontal steam engine. | 0:17:27 | 0:17:30 | |
The man who had the idea of connecting the cylinder to the crankshaft | 0:17:30 | 0:17:35 | |
is reputed to have been Richard Trevithick. | 0:17:35 | 0:17:39 | |
He and a gentleman in Leeds, Matthew Murray, developed the horizontal engine. | 0:17:39 | 0:17:45 | |
There were thousands of engines like this made, | 0:17:45 | 0:17:48 | |
from little, teeny ones, 3ft long, | 0:17:48 | 0:17:51 | |
to the biggest one on record, made by Hick Hargreaves's of Bolton. | 0:17:51 | 0:17:56 | |
Reputedly, the cylinder were ten feet long. | 0:17:56 | 0:18:00 | |
The horizontal steam engine was much easier to manufacture in all sizes | 0:18:00 | 0:18:06 | |
and it didn't need a great big, tall engine room. | 0:18:06 | 0:18:10 | |
To build an engine like this, all you needed was a big lathe, | 0:18:10 | 0:18:15 | |
a shaper and a good iron founder, | 0:18:15 | 0:18:17 | |
and you could make it in a shed in the back yard. I've more or less done it myself, once or twice. | 0:18:17 | 0:18:21 | |
That's the cylinder. That's the connecting rod. | 0:18:21 | 0:18:26 | |
That's the crank pin. There's no bending or forging involved in it. | 0:18:26 | 0:18:30 | |
The crankshaft is an iron bar. The disc is cast. | 0:18:30 | 0:18:34 | |
And the flywheel is cast in two halves. | 0:18:34 | 0:18:38 | |
It was a very efficient way of driving machinery. | 0:18:38 | 0:18:41 | |
And as these engines got bigger and bigger, | 0:18:41 | 0:18:44 | |
they could drive literally hundreds of machines | 0:18:44 | 0:18:48 | |
on four or five floors of a factory. | 0:18:48 | 0:18:52 | |
When steam began to replace water power, two things were needed - | 0:18:52 | 0:18:57 | |
plenty of coal and a good transport system. | 0:18:57 | 0:19:00 | |
Here in Wigan, where coal stuck out the floor five foot thick nearly everywhere, | 0:19:00 | 0:19:07 | |
it fast became a boomtown. | 0:19:07 | 0:19:09 | |
I suppose it was like anywhere else. | 0:19:09 | 0:19:12 | |
In winter, you wouldn't be able to see for the smoke coming out of the great chimneys. | 0:19:12 | 0:19:19 | |
All the mill owners and pit owners lived in country mansions | 0:19:19 | 0:19:23 | |
built out of the ill-gotten gains of the lads down below. | 0:19:23 | 0:19:28 | |
The earliest factories only employed 20 or 30 people. | 0:19:28 | 0:19:32 | |
But by the mid-19th century, they'd built great places like this behind me, | 0:19:32 | 0:19:39 | |
which could do many different processes and employ hundreds of people. | 0:19:39 | 0:19:45 | |
This is Trencherfield Mill at Wigan Pier, | 0:19:45 | 0:19:48 | |
and it houses one of the world's biggest surviving mill steam engines. | 0:19:48 | 0:19:54 | |
William Woods built his mill here in 1907. | 0:19:54 | 0:19:57 | |
It was a state-of-the-art spinning mill - | 0:19:57 | 0:20:01 | |
fireproof floors, five storeys high, | 0:20:01 | 0:20:03 | |
and room for 1,000 employees. | 0:20:03 | 0:20:06 | |
And now I'm going to see if they'll let me play with the engine. | 0:20:06 | 0:20:11 | |
This great engine behind me | 0:20:15 | 0:20:18 | |
once drove all the machinery on five floors. | 0:20:18 | 0:20:21 | |
It were built by John and Edward Wood's of Bolton about 1907. | 0:20:21 | 0:20:26 | |
I'm going to have a do at making it go. | 0:20:26 | 0:20:30 | |
You've got to turn this great valve. | 0:20:30 | 0:20:32 | |
If all the connecting rods are in the right shop, it'll set off. | 0:20:32 | 0:20:37 | |
Here we go. HE GRUNTS | 0:20:37 | 0:20:40 | |
Hmm. | 0:20:41 | 0:20:42 | |
Bit stiff on the valve. STEAM HISSES | 0:20:42 | 0:20:45 | |
WHEEL SQUEAKS | 0:20:45 | 0:20:48 | |
CLATTERING | 0:20:48 | 0:20:50 | |
This engine is what's known as a "tandem cross compound". | 0:20:50 | 0:20:56 | |
Triple expansion - it's got four cylinders. | 0:20:56 | 0:20:59 | |
In the small ones comes the high-pressure steam. | 0:20:59 | 0:21:03 | |
It's exhausted into a receiver | 0:21:03 | 0:21:05 | |
and then it goes into the low-pressure ones - the big'uns. | 0:21:05 | 0:21:10 | |
And when it had the grand opening, | 0:21:10 | 0:21:13 | |
each side of the engine were christened. | 0:21:13 | 0:21:17 | |
They're called Rina and Helen - the daughters of the engineering company that built 'em. | 0:21:17 | 0:21:23 | |
It's 2,500 horsepower. | 0:21:25 | 0:21:28 | |
METAL CLATTERS AND STEAM HISSES | 0:21:31 | 0:21:36 | |
It's fantastic, in't it, really, the size of the bits and pieces? | 0:22:03 | 0:22:08 | |
You know, you think about your Mamod at home, | 0:22:08 | 0:22:12 | |
and you've got a connecting rod here which must weigh about three tonnes. | 0:22:12 | 0:22:17 | |
An incredible piece of tackle! | 0:22:17 | 0:22:21 | |
They did things in a grand style. | 0:22:22 | 0:22:25 | |
This particular part of the building is called the rope race. | 0:22:31 | 0:22:36 | |
The reason for that is obvious - the ropes are all racing round! | 0:22:36 | 0:22:41 | |
There'd be as many as four or five to each floor, | 0:22:41 | 0:22:44 | |
and altogether, on the drum, | 0:22:44 | 0:22:47 | |
I think there's 55 grooves and the drum weighs 70 tonnes - that's one hell of a wheel, innit? | 0:22:47 | 0:22:54 | |
In the days when these things were run commercially, this were quite a frightening place to be. | 0:22:54 | 0:23:01 | |
There's daylight shining in now, | 0:23:01 | 0:23:03 | |
but when it was full of rope all going in different directions, it were quite frightening. | 0:23:03 | 0:23:11 | |
The only time they could mend them was in the middle of the night. | 0:23:11 | 0:23:16 | |
The rope splicer came at night - | 0:23:16 | 0:23:18 | |
they didn't do many night shifts at cotton mills - to splice a new piece. | 0:23:18 | 0:23:24 | |
Two inches' diameter. | 0:23:24 | 0:23:26 | |
Made of cotton. | 0:23:26 | 0:23:29 | |
The industrialisation of the great cities | 0:23:37 | 0:23:40 | |
put a terrible strain on the antiquated water and sewage systems. | 0:23:40 | 0:23:46 | |
Many new reservoirs had to be built | 0:23:46 | 0:23:49 | |
and, to pump water to them, many new pumping stations had to be built. | 0:23:49 | 0:23:54 | |
This is one of the more ornate. | 0:23:54 | 0:23:56 | |
Papplewick, built in 1884, | 0:23:56 | 0:23:59 | |
pumped water to the city of Nottingham all the way through till 1969. | 0:23:59 | 0:24:06 | |
These are the six Lancashire boilers that made the steam to drive the pumping engines. | 0:24:06 | 0:24:13 | |
They were made in Manchester by W & J Galloway. | 0:24:13 | 0:24:16 | |
Mr Galloway improved the Lancashire boiler by inserting vertical water tubes at the end of the fire tubes, | 0:24:16 | 0:24:23 | |
which greatly increased the steaming capabilities. | 0:24:23 | 0:24:27 | |
They used to burn five tons of coal a day on three of them. | 0:24:27 | 0:24:32 | |
The others were on standby. They did that at waterworks, just in case. | 0:24:32 | 0:24:37 | |
The pressure's getting a bit low now. | 0:24:37 | 0:24:40 | |
-Come on, Geoff. -I've done one side, Fred, so if you'll fire this side... -Right. | 0:24:40 | 0:24:47 | |
These two double-acting beam engines | 0:25:09 | 0:25:12 | |
are thought to be the last two that James Watt and Company ever made. | 0:25:12 | 0:25:17 | |
They pump 1.5 million gallons of water a day | 0:25:17 | 0:25:21 | |
from a well 200 feet deep, | 0:25:21 | 0:25:24 | |
and then a further elevation of another 100 feet, | 0:25:24 | 0:25:28 | |
and then it went by gravity all the way to Nottingham. | 0:25:28 | 0:25:33 | |
Although these engines were built in 1881, | 0:25:33 | 0:25:36 | |
they still use the old-fashioned Cornish principle, which proves how successful and economical | 0:25:36 | 0:25:43 | |
the Cornish beam engines were, | 0:25:43 | 0:25:45 | |
and how they lent themselves to pumping water. | 0:25:45 | 0:25:50 | |
It's interesting that, | 0:25:50 | 0:25:52 | |
by this time, James Watt and Company | 0:25:52 | 0:25:56 | |
had reverted to using high-pressure steam. | 0:25:56 | 0:25:59 | |
James Watt himself once said | 0:25:59 | 0:26:02 | |
that Richard Trevithick should be hung for using high-pressure steam because of its danger. | 0:26:02 | 0:26:09 | |
RHYTHMIC CLATTER AND HISSING STEAM | 0:26:09 | 0:26:12 | |
That lovely noise takes me back a bit! | 0:26:16 | 0:26:19 | |
I remember, as a lad of about 16 or 17, | 0:26:19 | 0:26:23 | |
rather fearful, climbing the engine house steps | 0:26:23 | 0:26:27 | |
and looking at the thing going round through the window and seeing the engine minder in an easy chair. | 0:26:27 | 0:26:34 | |
But he wouldn't be asleep - | 0:26:34 | 0:26:37 | |
he'd be listening for any strange change | 0:26:37 | 0:26:41 | |
in the pattern of noise coming from the thing, denoting something wrong. | 0:26:41 | 0:26:46 | |
CLACKING AND CLICKING | 0:26:46 | 0:26:51 | |
These great beams transfer the power from the piston rod | 0:26:58 | 0:27:02 | |
to the pump rods down the well, or the shaft. | 0:27:02 | 0:27:06 | |
They weigh 13 tonnes apiece. Ever wondered how they got them up here? | 0:27:06 | 0:27:11 | |
There were no fancy cranes then! Pictures exist, | 0:27:11 | 0:27:16 | |
showing great piles and baulks of timber. | 0:27:16 | 0:27:20 | |
They were basically jacking up the beam as the engine room came up. | 0:27:20 | 0:27:25 | |
They slid them in, over the central beam that they pivot on. | 0:27:25 | 0:27:29 | |
The hangers in the roof weren't for lifting the whole thing up. | 0:27:29 | 0:27:35 | |
They were for lifting one end up and maybe replacing a bearing. | 0:27:35 | 0:27:41 | |
The engines and the building were finished well under budget. | 0:27:42 | 0:27:48 | |
And with all the money they had left over, | 0:27:48 | 0:27:51 | |
they made embellishments like stained glass and terracotta bits outside | 0:27:51 | 0:27:56 | |
and fish and birds and everything. | 0:27:56 | 0:27:59 | |
It's sad that the general public | 0:27:59 | 0:28:01 | |
never saw any of this - it was only the waterworks superintendent | 0:28:01 | 0:28:07 | |
and maybe some of the operatives, you know. | 0:28:07 | 0:28:10 | |
But it shows how proud the Victorians were of their engineering achievements. | 0:28:10 | 0:28:17 |
