ENGINES OP SAVERY ANO NEVVCOMEN., Savery's Engine.?Boilers and their Appendages.?Working Apparatus.? Mode of Operation.?Defects of the Engine.?Newcomen and Cawley.? Atmospheric Engine.?Accidental Discovery of Condensation by Jet.? Potter's Discovery of the Method of working the Valves. (31.) The steam engine contrived by Savery, like every other which has since been constructed, consists of two parts essentially distinct. The first is that which is employed to generate the steam, which is called the boiler, and the second, that in which the steam is applied as a moving power. The former apparatus in Savery's engine consists of two strong boilers, sections of which are represented at D and E in fig. 7; D the greater boiler, and E the less. The tubes T and T' communicate with the working apparatus which We shall presently describe. A thin plate of metal B is applied closely to the top of the greater boiler D turning on a centre c, so that by moving a lever applied to the axis c on the outside of the top, the sliding plate R can be brought from the mouth of the one tube to the mouth of the other alternately. This sliding valve is called the regulator, since it is by it that the communications between the boiler and two steam vessels (hereafter described) are alternately opened and closed, the lever which effects this being constantly wrought by the hand of the attendant. Two gauge pipes are represented at G, G', the use of which is to determine the depth of water in the boiler. One G has its lower aperture a little above the proper depth, and the other G' a little below it. Cocks are attached to theupper ends G, G', which can be opened or closed at pleasure. The steam collected in the top of the boiler pressing on the surface of the water forces it u...
