TO ALL WHOM IT MAY CONCERN:

Bc it known that ITuo.MAs SIMMONS, of New York, in the county of New York, and in the State of New York, have invented certain new and useful Improvements in Vacuum Ship-Pumps; and do hereby declare that the following is a. full, clear, and exact description thercof,refcrence being had to the accompanying drawings, making a part of this specification.

My invention consists, in part, of a hollow vessel of nictal or any other suitable substance, and of any given dimensions, or any conceivable form, as circumstances and location may permit but a cylindrical form is preferred on account of strength and convenience. Therefore, in I i Figure I, A represents a hollow. vessel, of a. cylindrical forin, made 4air-tight and lying horizontally on and supported by a bed or trongh, B, and fasten ed to the trough by means of screw-bolts through flanges projecting from the sides of cylinder, and resting on the edges of trough B and is thus held in position. Through the centre of cylinder A runs-a perforated plate, a, from end to end, filling the entire width of the cylinder,

4(thickness of plate boiler iroml" At oneend of cylinder A is a box, C, which contains a. check or flap-valve,E.

where cylinder rests.

Box C is `so constructed as to bc open on top side, and with plate, yoke, lever, and 'screw s t w, so'as lto close quickly andeasily. This openingen the upper side is se as to remove any substance that might pass into the valve and obstruct its action. The other opening is'to passfwa'ter or any other liquid into cylinder A. By means of a corresponding hole'in the end inside of box C is arvalve-fall and valve E. The valve-fall is made o f a square plate of metal 'with square hole through the centro, and fitted inbox C at any angle, so that the water in passing through will work off any substance which may collect there on the valve-faces, and thus interfere with its. action or the working of the valves. The valve E is ina-de of a flat piece of metal, or suitable substance faced with rubber or any elastic substance, then fastened in such manner as to rise and fall by means of a hinge formed by the rubber, 'so as to close the square hole through valve-face perfectly tight.. The rubber is used so that sand or any-small hard substance nould indentitself into it and not prevent it working or acting. On thevlower side of box ,C is a nipple, F, or a screw-connection, forV the purpose of attaching a pipe/or hose through which the water is to be drawn. Box C is arranged with `flanges so that .it can be bolted against the end of cylinder A.' On the top of cylinder Ais a nipple, G, for the purpose of making a steam-connection to admit steam, and is worked by hand or'otherwise, by means of an ordinary cock or valve. On the opposite end of cylinder A, to which box C is fastened, is valve-seat jand chamber II, in which works valve I. Seat and chamber H is a. round cylinder with flange aton'e end to fasten with screw and bolts to. cylinder A, and the other end is turned or forced off true and the cylinder part bored out. In this the stem, ortianges, orrwings'of valve play as a. guide to the valve, while the face of the valve is made to correspond to that of the seat and face, with rubber or other elastic substance for the same purpose that the other valve is used for in box C. VThis valve I is worked byrmeans of a lever, .I, which is to be worked by hand or otherwise, and stands in an upright position,V and is supported on shaft K. This is worked and fastened by means of boxes, journals, and collars on trough BJ By the action of the lever onvalvc I it may be forced shut or open, as desired. i 'The trough B is made ofwood or metal, as desired, and acts in the double capacity of a betbplate and .for'the conducting of the water or liquid matter discharged and delivered bythe pump. It ismadeof two sides, one endand bottom, with one end hollowed out so as to fit the circle of cylinder A, with corresponding circular bearer at the end Now, having. described my invention by detail, vI will proceed to show its working operation: First, steam is admitted at connection G into cylinder A. When the air in A has been displaced by steam it is then shut ed, when a vacuum is formed in A, sothat water shall meet with no resisting pressure when being forced up through a pipe or hose attached to screw-connection F, into box O through valve E, and is thrown upon perforated plate a until cylinder A is filled. Steam is then admitted into'vessel A through G, an-d forces open delivery-valve I, and the contents are discharged into trough B and conducted oit` with the water discharged.

`The valveI is then forced and heldA shut by means of lever J, and the operation repeated.

New, having thus fullydescribed'my invention, and the mode of working it, what I cla-im and desire to secure by Letters Patent, is-

1. The arrangement of cylinder A, perforated plate a, and box O, substantially as herein set forth.

L2. The arrangement of thecylinder A, stcaminlet G, chamber II, valve I, and lever J, in the manner and for the purposes set forth. y I v 4 i In testimony that I claim the'foregoing I have hereunto set -my hand this 13th day of April, 1867.

THOMAS SIMMONS.
