UNITED STATES PATENT EErcEo ALGERNON A. BURR, `OF GAMPTON, ILLINOIS.

IMPROVEMENT IN PUMPS.

Specilication forming part of Letters Patent No. 159,152, dated January 26, 1875; application filed October 17, 1874.

To all whom -it may concern.' A

Be it known that I, ALGERNON A. BURR, of Oampton, in the county of Kane and State of Illinois, have invented a new and useful Improvement in Pumps; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure l i's a vertical central section of a pump embodying my saidA improvement and Fig. 2 is a transverse section or plan vtaken on the line x x, drawn across Fig. l.

Similar letters of reference indicate like parts in both iigures of the drawing.

My invention relates to that class of pumps in which the piston-rod is connected to a submerged cylinder, the former being hollow and made to act as the pump-stock; and the improvement consists in the combination ofthe respective parts, all of which will be more fully understood by the following description.

In the accompanying drawing, A represents the platform covering the well. B is a vertical post or bar, which is permanently attached to the lower surface of the platform, and eX- tends downward to the bottom of the well. The lower extremity of this post is made sharp, by which means the saine is readily driven into the earth, thereby holding the same in a fixed position. C is the plungerrod, which is iirinly affixed to the side ofthe l bar near its lower end, as shown in Fig. l. D is the piston-rod or pump-stock, which is permanently secured at its lower end to the upper end of a vertical cylinder,F. This piston-rod is made hollow, and communicates with a chamber, E, formed upon the side of the cylinder. An opening, e, is formed in the walls of said chamber, which communicates with the interior of the cylinder at or near its lower end. The upper end of the cylinder is provided with a cap or bulk-head, d, through which the lower portion ofthe plunger-rod loosely passes. Firmly secured upon the lower. end of this rod is a disk or plunger, G, which is adapted The lower extremity of the cylinder is provided with an opening, H, which is so arranged as to form a valve-seat, upon which t-he main valve f is secured. This valve and seat may be of any known form that will tightly close the opening, and is so arranged that as the cylinder is moved downward the valve is lifted from its seat, allowing the water to enter the same through opening H, and as the cyliiider is raised the valve reseats, closing the opening, and, by the action of the plunger, the water is forced from the cylinder into chamber F through opening e, to and through the piston-rod. K is a check-valve, which is seated within chamber F, slightly above opening c. This valve is so arranged as to reseat as the cylinder is moved downward, thereby retaining the water within the piston-rod as the cylinder is filled. Firmly secured to the upper surface of the platform is a metal rack, L, within which is pivoted a horizontal arm, M. Affixed to the center of this arm is a vertical lever, M'. The arrangement of said arm and lever are such that as the lever is reciproca-ted an alternate tilting movement is impart-ed to the arm. One end of said arm is pivoted to the piston-rod at n, and is provided at its opposite end with an adjustable weight, P, which is so arranged as to admit of being moved toward or from its center. This weight acts to counterbalance the weight of the pistoii-rod and cylinder, thereby insuring an easy action of the pump.

The operation of my invention is as follows: As the lever is moved forward, the cylinder is forced downward by the action of the piston-rod, causing the main valve to open, thereby allowing the water to-enter the cylinder, and by a backward movement of the lever the cylinder is raised, closing the main valve, and bringing the plunger iii contact with the water, and by its pressure the water is forced from the cylinder into the chamber and through the piston-rod.

Having thus described my invention, I claim- The combination of post B, plunger G, piston-rod I), cylinder E, chamber F, valves f and K, and gravitating-lever M', all operating as specified.

The above specification of my invention Signed by me this 20th day of June, 1873.
