SPECIFICATION formingpart of Letters Patent No. 225,398, dated March 9, 18810.

' Application filed July 1, 1879.

To all whom it may concern Be it known that I, DAVID 0. LEE, of Kirkwood, Missouri, have made a new and useful Improvement in Pumps, of which the following is a full, clear, and exact description, reference being bad to the annexed drawings, making part of this specification, in which Figure 1 is a view, in perspective, of the invention, one of the side plates or walls being removed; Fig. 2, a side elevation, partly in section; Fig. 3, a detail, being a vertical section taken through the discharge-valve chamber; and Fig. 4, a detail, being a view, in perspective, of the inlet-valve box.

The same letters denote the same parts.

The present invention is an improvement in pumps wherein the piston in its operation has a reciprocating rotary movement upon a hearing within the cylinder; and it consists partly in the manner of holding the piston in its bearing, partly in the means for operating the piston, partly in having a pair of the cylinders with their pistons moving and operating as described, and by means of the same main rod, and partly in the general combination of all the parts.

Referring to the drawings, A A represent two similar chambers corresponding to the cylinders of the ordinary pump. They are of the triangular shape shown.

B B represent the pistons. They are in the form of flat disks, and they have a vibrating movement between the upper, to, and the lower, a, surfaces of the chambers, the disks in their movement turning upon the inner ends, I) b, of the chambers. The disks are not hinged to the ends 12 b, but turn loosely therein, the aim being to reduce the liability of their becoming clogged by dirt, and also to enable them to be readily removed from the cylinders when desired.

G O represent the piston-rods. They are connected at their inner ends with the pistons B B, and at their outer ends with the arms D D. The rods are curved, as shown, to enable them to work properly through the perforations a in the shell of the chamber. The arms DD are of the shape shown, and at one end are connected with and made to turn upon a bearing, d, and at the other end, 01, are jointed to the arms 0 e, which, in turn, are

attached to the main rod E. The are preferably jointed at 6 F F F F represent the valves for admitting the water to the chambers A A, two of them being above the pistons and two beneath.

G G represent the discharge-pipes, (shown in Fig. 3 and in dotted lines in Fig. 2,) the pipe G leading from the spaces in the chambers A A above the pistons, and the pipe G leading from the spaces beneath the pistons. These pipes G G at their outer ends connect with the discharge-valve chamber H. The latter is provided with two valve-seats, h and h, arranged as shown in Fig. 3, inclosing a V shaped chamber, 1%, the lower end, h of which forms a bearing for the outlet or discharge valve I to turn upon. The latter has a rotary reciprocating movement between the seats h h, alternately opening and closing the passages from the pipes G G, respectively, as is hereinafter described.

J represents the discharge-pipe leading from the chamber h The operation is as follows: Water being admitted into the chambers A A, an upward movement of the rod E causes the pistons B B to turn upon the bearings Z) t in an upward direction and to expel the water from above them into the chamber W, the water passing arms e a through the pipe G'into the chamber 31?, and

thence out through the pipe J. This movement throws the valve I over onto the seat h, closing thereby the upper end of the pipe G, and preventingthe descentof the water through that pipe. The downward movement of the rod E and pistons B B then takes place. The water is then expelled from beneath the pistons, through the pipe G, and thence into the chamber 7L2 and pipe J, the valve I now being thrown back again upon the seat It and closing the pipe G. The valve I is thus made to vibrate upon the bearin g k between the seats hi1 at each movement of the pistons. The outlets from the pipes G G are opposite the upper end of the valve I in order to facilitate the. proper working of the latter. The valve I is loose in the chamber k and can be easily examined and removed by opening the chamber H. The interior of the chambers A A can also be readily reached by taking off one of the side plates, c of the pump.

I claim-- 1. The combination of the triangular chamber A, piston B, and rod 0, said piston turning loosely in the end I), substantially as de- 5 scribed, and for the purposes set forth.

2. The combination of the chamber A, bearing 1), piston B, rod 0, lever D, and bearing 01,-

substantially as described.

3. The combination of the chambers A A, 10 pistons B B, rods 0 O, pipes G G, chamber h, valve I, and pipe J, substantially as described.
