JoHN M. L'UNoUEsT, oE GRIFFIN, GEORGIA IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 23,100, dated March l, 1859 Reissue No. S65, dated December 13, 1859.,y

These openings n n are closed by the ,ball- To all whom it may concern:

Be it known that I, JOHN M. LUNQUEsT, of Griffin, in the county of Spalding and State of Georgia, have invented certain new and useful Improvements in Pumps; and I do lhereby declare that the foilowingfis a full, clear, `and exact description of. the same, reference being had to the annexed drawings and to the letters of reference marked thereon.

'lhe nature of my invention consists in the peculiar arrangement otthe several parts, which will be hereinafter described.

In order that those skilled in the arts may make and usc my invention, I will proceed to describe its construction and operation.

In the accompanying drawings, Figure l represents a section of the Working parts of the pump. Fig. 2 is a side elevation. Fig. 3 represents a top vieu7 ot' the crank-handle. Fig. 4 is a bottom vieur of the four cylinders. Fig. 5 is a vievv of the'bottom ofthe air-chambeI, showing the valves in it.

In the tigures, A represents the board or frame-piece to which the pump is attached.

B B B B represent four cylinders, which are placed together in the manner shown in Fig. 4. The length andr size of these cylinders will depend upon the desiredcapacity of the pump.

D D represent piston-rods, which are connected at their lower extremities with the pistonheads C C, which are four in number, and which play in the cylinders B B. The piston-rods D are connected and form a joint with the rods D D D D at their upper ex tremity.

H is a crank-handle, which is secured in proper bearings at the top of the pump. This handle has four cranks, as will be seen, which are represented by .r .r w .'r. To these four cranks attach the upper ends of the rods D Dl D D. The pistonheads C C are provided With apertures t' Ii, through which Water passes into Ithe pump. These apertures are covered with four balls, which serve as valves, and are represented by a a.

F represents an air-chamber, Which is l0- aud extends downinto it almost to its ybottom. When this pump is placed in order to be operated, the cylinders and airfhamber are submerged in the Water, as is represented in Fig. l. When this is done,the operator turns the crank-handle H, and the pistonheads U C are set in motion. The Water enters the cylinders B B through the apertures M and close them, the Water in the cylinders being raised and forced through the openings n n in the bottom of the air-chamber F. So. long as the Water is being'forced into the airchamber the balls do not cover the openings n n, but the moment the piston-heads begin to descend the balls a a fall into the openings n n and prevent the Water from returning into the cylinders. As the operation continues the air-chamber F becomes partially illed with Water, and when the air above the Inouth of the pipe becomes compressed the Water is forced up the pipe E and is discharged above its desired point. It is evident that as the Weight of the Water is lifted by the pistons,

the rods l) D need not be very large and heavy. They require vstrength sufficient to head down again into the bottom of the cylinders. The balls a a are contined in so small a space within the chamber F and so close together that the sides ot' the chamber and the balls themselves keep each other in proper position to cover their respective openings.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

The arrangement ottwo or more cylinders, B B, piston-heads C ballAvalves a, a, air chamber F, and valves c a', said valves being kept in position by proximity to each other and the sides ot' the chamber F, substantially inthe manner and for the purpose herein specified.
