The Hathorn Davey horizontal tandem compound pumping engine formerly used at Marine colliery is plinthed just above the cleared site. The cylinders are 36" and 68" in diameter with a stroke of 120".
Does anybody have an arrangement of how the engine drove the pumps and at what sort of speed the engines of this type operated.....

Lovely relic, better plinthed than broken up...

Take a guess at 20 strokes/min or less, do you have a pic of the pump end of the piston rod, (a bit more to the right of your pic, I think)?

Edit: Was this a push/pull affair or did it have crank/flywheel etc?

Looking at pics 6 & 7 the piston rod pin has been burnt out at the crosshead slides.

Another guess is it operated some sort of bellcrank to a double acting pump down shaft.

Further research indicates it was "non-rotative differential pump"?

i was leaning towards the bell crank idea... just wondered if any one out there had a diagram of this type of colliery installation.

OK, a bit more, scroll quarter way down page for differential pump.

http://www.fao.org/docrep/010/ah810e/AH810E06.htm

All we need now is the bit between engine and pump.

As a differential pump is double acting it could have been driven by downshaft rods which would tie in with the double acting tandem steam cylinders.

And finally at 50,000 gallons/hour it ran at 7 strokes/min. 🙂

Cambridge Pumping House is a bit of a forgotten relic, which is a great shame as it is a very nice specimen. The Pump House adjacent to the Space Centre in Leicester is also well worth visiting, if you go there

Came across these a bit back while browsing loking for engine diagrams. Sorry they're not any bigger - but I wasn't prepared to pay the money the advertiser wanted - I really object to people doing this to old info - it should belong to everybody (rant over).

Anyway:

I may have some more illustrations somewhere of my own, if I can find them.

This shews the layout at the Muke Mine Japan. The engines are connected to an angle bob and then to Cornish Pit work.
Engine cylinders are: 45" x 90" 12' stroke.
Engine speed six strokes PM pumping 9000 Gals per min.each

Excellent links and pics, never seen the double bell crank set up before although it must have been quite common.
Nice balanced arrangement.

ICLOC has asked me to pass on his thanks to those that responded to his request. He is unable to do this himself because of work commitments.

My thanks for the pics & info as well. :flowers:

Would I be correct that the small steam cylinder in pic 4 is possibly a barring engine, seems it would need one to start from dead centre, (no flywheel barring facility)?

Yes, indeed, better plinthed than broken up and it took a bit of lobbying of relevant authorities to achieve that, also helped by the Ebbw Vale Garden Festival.

It's now up to us to ensure this almost unique survivor carries on surviving.

There was/is another larger one in South Wales at the former Llanover Pumping Shaft at SO 180008. I took some pictures of it in the 1980's when the shaft was still pumping (not the engine) and I believe that as it was in a basement after pumping ceased the whole site was simply buried. Clarification would be welcome.

Yes, I'll have it - what is it?

Excellent link, Thanks.
It would appear the the small steam cylinder (left) in pic 4 is the subsidiary cylinder and the one on the right the cataract cylinder.
All becomes clearer. 🙂

Edit: With the extra info it would appear that the engine would start from any position.

Does not look good.

The shaft cap seems to be visible on Google and appears to be monitored for water level.
Anyone got a plan of the original colliery site, may be worth a poke around.

Edit: Found some pics.

This engine used to be in the basement of one of the winding houses and was rebuilt on this concrete plinth which is how they managed to get the rods in the above picture in the wrong place.

That rod off the end of the crosshead slide has been put on 180 degrees out - it should point down not up; then the rod connecting it to the long rod from the valve control gear would be parallel to the ground not stuck up at a funny angle. Perhaps it was done deliberately to avoid having to dig a trench in the ground to accommodate it.

And another thing! The cylinder end covers are fixed to the cylinder bodies by lots of numbered nuts and bolts: numbered so that they could be replaced correctly after repair, but they haven't been. I've had many a sleepless lunch hour worrying over that.

Yes, I'll have it - what is it?
