The Savery principle still survives in the action of the well-known pulsometer steam pump. Denys Papin, the pupil and assistant of Huyghens, continued experimenting upon the production of motive power, and in 1690 published a description of his attempts at Leipzig, entitled "A New Method of Securing Cheaply Motive Power of Considerable Magnitude."
With Savery and Cawley, he invented and in 1705 patented the atmospheric steam-engine by which he is known, and which, as told by Arago, gave place to the superior invention of Watt.
But William Savery was no ordinary man, and the young people at Earlham prepared to listen to him, in case he "felt moved" to speak, with no ordinary attention. Giving an account of this visit, Richenda Gurney admitted that they liked having Yearly Meeting Friends come to preach, for it produced a little change; from the same vivacious pen we have an account of that memorable service.
Several eminent and ingenious men, previous to this, had proposed to propel vessels by steam power, among whom were Dr. Papin, of France, Savery, the Marquis of Worcester, and Dr. John Allen, of London, in 1726. In 1786, Oliver Evans, of Philadelphia, and about the same time Dr.
I there saw the names, and read the letters, of William Savery, Thomas Scattergood, and a host of others, who have long since gone to their everlasting rest. I hope, however unworthy, to join them at some day, not very distant." "Next day after to-morrow, it will be fifty years since I was married to thy dear mother. How fresh many of the scenes of that day are brought before me!
At the age of nine he started at farm work and at twelve he was big enough to handle logs and work in the woods. Savery took the stand in his uniform of slavery, red mackinaw shirt, stagged-off pants, caulked shoes, and a battered slouch hat in his hand.
The next morning William Savery came to breakfast, and preached to our dear sister after breakfast, prophesying of the high and important calling she would be led into. What she went through in her own mind I cannot say, but the results were most powerful and most evident. From that day her love of the world and of pleasure seemed gone."
Even the judge tired of these tactics and told the prosecution that there was no way to stop them from asking the interminable questions but it was merely a waste of time. But all of Cooley's dilatory tactics could not erase from the minds of the listeners the simple, earnest, sincere story Fred Savery told of the death of his fellow worker, Hugo Gerlot.
Then in 1705 Newcomen and Cawley, working with Savery, took up Papin's idea, separated boiler from cylinder, and thus produced a vacuum into which atmospheric pressure forced the piston and worked the pump.
"By the Lord Harry, Master Savery," shouted the colonel, loud as he could pitch his powerful voice, as the big paymaster strode by, his horse having been shot under him, "did I not order you, unless you remained with the General, to stay with your iron chest? Go back, sir, immediately." To which Savery answered, playfully, "Mind your regiment, Master Isaac.
