Savery's Engine
Before a fire is made unscrew G & N , being the two small gauge pipes and cocks belonging to the two boilers,and at the holes fill L,the big boiler two thirds full, and D, the small boiler,full. Then light the fire at B and when the water in L boils, the regulator Z must be pushed forward as far as it will go, which makes all the steam in L pass with force through O into P, pushing all the air before it, through the clack r; and when all is gone the bottom of vessel P will be very hot. Then pull the regulator shut which means you stop O, and force the steam through oO into Pp until that vessel has discharged its air through R up the force pipe S. Meanwhile the steam condensing in vessel P, a vacuum is created, so that the water will rise up through the sucking pipe T lifting clack M and fills vessel P

The illustration is excellent Spitfire. We discussed Savery's engine on the forum some time ago and concluded that it was never used to pump a mine but was used as a means of powering fountains in grand estate gardens. Does your source indicate otherwise? My belief is that the first mine pumping engine was Newcomen's machine erected near Dudley (the land of my fathers).

I'm sorry JR I didn't see your post.
He certainly hints at being in Cornwall but lists the duties of his engine for : draining fens, ships, and working fountains but he also makes it clear that his engine will drain mines far cheaper than manual labour

Savery's pump was developed into this.

Not certain of the history but the 'Pulsometer' trade name carried on to a range of centrifugal pumps.

I know this engine has appeared on another thread but it deserves its place here.
The only comment a great uncle of mine ( who was a captain at Basset mines ) was that it burnt a lot of coal and pumped a lot of water.
To be fair, Davey the designer always said that the engine would have been far more efficient had he not been forced to use a second-hand cylinder on the LP side from a redundant engine to cut down cost.
It was said the weekly coal consumption on the Basset Mines was equal to that of the City of Truro.

Nice. 🙂

Came across this drawing of a Worthington-Simpson Triple expansion pump many years ago in a collection of blueprints relating to the Oakelely Quarries. The rest were all from the electrification of 1906. Quite what the origin of this was is not at all clear, it may have been a proposal to use steam rather than electricity for pumping, but I have found no reference to it. It was certainly never installed.

The recent thread on the Llanharry mine pumps has mention of spears at 20 inches square, would this be near the upper limit for such kit?

Bit of a tricky one this. The drawing in your PM indicates that a spear is a bucket lift and so that would be in the round, yet your measurements are in the square which would be the case for a plunger pump.
Either way it would make no difference as everything would be balanced out and be within the capabilities of such an engine

Forgetting the balance issue and the definition of a 'spear' for a moment. Would the timber beam that transmits power down the shaft be considered in the the large range at 20 inches square? 🙂

Not at all, it would be governed by the size of the rods

Peakland Lead Mines and Miners - Parker and Willies - has a diagram of a Newcomen Engine installed underground in Yatestoop Mine, 1792 - one has to wonder at the size of the task - excavating the space required, and building the boiler and engine in situ.

As previously mentioned on this forum, the Leawood Pump at Cromford, Derbyshire has a Cornish Beam Engine in working order.
