IMPROVEMENT iN PUMPS.

Specification forming part of LettersPatent No. 35,508, dated June l0, 1862.

To aZZ whom it may concern:

Be it known that I, AsAHEL CooLEY, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improved Double-Acting ForcePump, theeonstruction and operation of which I hereby fully and accurately describe, the accompanying drawings making a part of this specification. i

Figure l is a longitudinal elevation. Fig. 2 is a longitudinal section. Fig. 3 is `a transversesection in thelineb b. Fig. 4is aface view of the valves c c and d d. Fig. 5 is` La transverse section of the piston in the line ff. Fig. 6 is a transverse section of the piston in the line m m. Fig. 7 is atransverse' section of the piston iu the line v o. Fig. 8 isna transverse section of the" piston in the line .fr x. Fig. 9 is a transverse section of the bottom piece, C, in the line h h.

The top piece, A, is attached to the cylinder which communicates with a series of induction-passages, e ecce e, Fig. 3, over which is a ring-valve, c c, `Fig. 4., or its mechanical with a series ofinductionpassages, 0 0 o o o o, Fig. 9, over which is a ring-valve, d d, Fig. 4. It has also a'central bolt, g, for the puri'astening in the bottom of the well.

The piston E E is arranged with a series of passages, Z Z Z Z Z Z, Fig. 5, communicating with an annular passage, r r, Figs. 2, 6, and 7, which also coinmuiliieates'by the passages s s s s s s, Figs. 2 and i8, and an annular passage, t t, Figs. 2 and 7, with a circular valve-chamber, a a, Figs. 2 'and 6. Within the valvechamber n a and-over the annular passage t t is a ringvalve,.i, Figs. 2 and 6, or its mechanical equi valent.

H, Figs. 7 and 8, is a central eductionport, which is closed by the valve S or its equivalent. i

Attached to the piston and communicating with the valve-chamber n n is a hollow piston-rod, F, which passesloosely through the top piece, A, and is extended to the top of the well and attachedto a lever or any other suitable device for working the pump.

The relative dimensions shown in the accompanying drawings adapt the pump to the capacity of bored or drilled Wells, the di-l ordinary purposes it may be simplified by increasing the diameter at p p p p, so that the passages e e e e e e may be made straight and vertical, in which case the bore of the cylinder may be extended to the valve-chamber ct a.

Operation-When the piston is moved upward,.the `water flows through the passages o o o o o o and the ring-valve d d, and iills the cylinder below the position, after which the passages o o o o o o are. closed by the valve cZ (Z. When the movement of the piston is reversed, this Water lifts valve S and passes through the port H and valve-chamber an, and is conducted through the piston-rod F to the top of the well. As the piston moves downward, the water ows through the passages Z Z Z Z Z Z, lifts valve c c, and fills the cylinder above the piston, after which the passagesZ Z Z Z Z Z'are closed by the valve c c, and as the movement of the piston is againreversed the water liows through the connected passages Z Z, r r, s s, t t, lifts the ring-valve t', passes through the same, and is discharged through the piston-rod F, while the cylinder is again filled below the piston, as before described. w

The pump may be worked slowly or rapidly without jar o r backflow of water, as the ports are all closed promptly by the weight of the corresponding valves as the movement of the piston is reversed.

I claim- 1. The manner described of filling the cylinder above the piston, to-Wit: by the Aemployment ofthe induction-ring valve c c, surrounding the Vbore of the cylinder at the top Vof the saine, the ports e e e e e e of which bcstantially as described, when combined with a pump-cylinder, and a tubular piston-rod, F, for the purposes set forth.
