UNITED STATES PATENT i FFTCE.

D. W. LEVIS, OF JANESVILLE. VISCONSIN.

PUlVLP.

Specification of Letters Patent No. 32,881, dated July 23, 1861.

To all whom it may concern:

Be it known that I, D. Vif. Lnwrs, of the city of Janesville, in the county of Rock and State of Wisconsin, have invented a new and Improved Mode of Constructing and Operating a Balancing Force and Litt Pump; and I do hereby declare that the following is a full, clear, and exact description ot' the construction and operation ot the same, reference being had to the accompanying drawings, making a part of this speciiication, like characters referring to like parts in each iigure.

Figure l, shows a side view of the pump, in elevation, inserted in a well, shown in vertical section. Fig. 2, represents a full size vertical section of the pump cylinder E, Fig. l, and shows the general construction of the same, and fully represents the peculiar combination of the lower pin and wing valve M, with the strainer F, which is attached to the lower part oit the cylinder' E, by screwing it into the same, as there represented. Fig. 3, is a ull size vertical section, representing` that part of the stationary pump case, which is attached and secured to the planking A, that covers and protects the mouth of the well WT, and also the upper and movable part C, to which is attached the water pipe D, thus connecting the upper and movable part of the pump case C, with the piston L. F 4, represents a 'uil size clutch band H, which is secured to the pipe D, by the key U. said band forming a scat for the equalizing lever gage G, which is secured to the clutch banc iii, by the bolt g. Fig. 5, represents the equalizing lever gage at full size. Fig. 6, represents a full size clutch band secured to the pipe D, by the key U', forming a guide for the balancing rod O, which is secured to the equalizing lever gage G, by the bolt f, at the top, said rod O, passing through the clutch band J, at z', to the cresu cent shaped plate K, which is attached to the piston barrel E, by the rods L Fig. 7 is a full size section on the line X, Y, Fig. 2, showing the plan of the wing valve M, and the location of the pin N. Fig. 8, represents a full size plan of the crescent shaped plate K., and the iiange L, which forms a part of the piston. f

The pump is operated by raising the lever or handle S, which has an oscillating fulcrum R, which is pivoted at the point Q on the bolt af, thus raising the movable case C, the pipe D, and the piston L, and at the saine time, and by the same motion, causing the piston barrel E, to descend by means ot' the balancing rods P, O, which are attached and connected to the piston barrel E, by means of the crescent shaped plate K and the rods i, thus causing a double stroke with one motion of the lever or handle S. Wvhen the lever, or handle, descends, the motion ot the several described parts is reversed, and the water made to iiow out at the orifice V. Li order to balance the pump, the pipe D is to be iilled with water, and if found to be too light, or out of balance the top of the rod P is to be carried in toward the tulcrum rod E, and the bolt c moved to the hole 7L or L, and at the same time the top of the rod O is to be carried out on the equalizing lever gage G, and the bolt f moved to the hole a.. Ti' the water pipe is found to be too heavy, a reverse movement of the several described parts is to be made.

l do not claim new the construction of the pump cylinder, nor the pin and wing valve, nor the construction of the pump case in two parts; but

I do claiml. The peculiar combination of the piston L, and piston barrel E, with the equalizing bar or lever gage G and the balancing rods P. O, substantially as and for the purpose -set forth and described.

2. The oscillating fulcrum bar R, combined with the lever or handle S. and the balancing rods P, O, and the movable case C, substantially as shown and described.
