Getting tough

My grandfather worked in a blacksmith shop when he was a boy, and he used to tell me, when I was a little boy myself, how he had toughened himself up so he could stand the rigors of blacksmithing.

One story was how he had developed his arm and shoulders muscles. He said he would stand outside behind the house and, with a 5-pound potato sack in each hand, he would extend his arms straight out to his sides and hold them there as long as he could.

After awhile, he tried 10-pound potato sacks, then 50-pound potato sacks. Finally, he got to where he could lift a 100-pound potato sack in each hand and hold his arms straight out for more than a full minute!

Next, he started putting potatoes in the sacks.

Savery's steam-driven water pump

In 1698, Thomas Savery received a British patent (No. 356) for a “New Invention for Raiseing of Water and Occassioning Motion to all sorts of Mill Work by the Impellent Force of Fire.” It was the first to harness steam for pumping water, used in draining mines, serving towns or supplying water to mills. Steam in a vessel was condensed by an external spray of cold water. A partial vacuum resulted and raised water from a lower sump. As high-pressure steam refilled the vessel, the water was forced to a higher level. His major problem was containing high-pressure steam since available construction materials were weak. The 14 year term was extended to 35 by Parliament in 1699. He also held a patent for ship propulsion (No. 347, 10 Jan 1696).«[Image: diagram of Savery's Miner's Friend steam powered pump.]
