Description
encircles STATES! l@NITE NON-FREEZING FORCE-PUMP.
SIECIEICATION forming part of Letters Patent No. 329,234, dated October 27, 1885.
Application filed September 12, 1884. Serial No.f142,902. (No model.) l
To all whom t may concern:
Be it known that I, WILLIAM M. STEVEN- son, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Non-Freezing Pumps, of which the following is a specification, referencebeing had to the accompanying drawings.
My invention relates to double-acting forcepumps for wells, cisterns, and sinks; and the invention consists in certain improvements in the construction and arrangement of the parts, whereby the operation of such pumps is rendered more perfect and the objections heretofore existing to their use are obviated.
My pumps are so constructed as to give a continuous and unbroken dow of water when using a hose or nozzle, and willwork with like facility in -winter and summer. Their construction is comparatively simple. They are easily operated, and occupy but small space compared with 'other descriptions of forcepumps.
In the accompanying drawings, forming a part of this specication, Figure 1 is a sectional view. Figs. 2, 3, 4, 5, 6, 7, 8, 9 are detached detailed views of some of the parts. Fig. 10 is a sectional View of the piston I, and shows the several parts of the valve I therein. Fig. 11 isa detached plan view of theslide A, rollers c, and part of the handle B. Fig. 12 is a detached side elevation of the valve J and a part ofl the piston-rod A. Fig. 13 is a plan view of the valve J detached from the pump, and shows the piston-rod Ain section.
The letter A indicatesa piston-rod, the upper end of which isattached to a slide, A, provided with two or more friction-rollers, a, and which is pivoted to the handle B. This slide is made of two pieces of metal, one of which is placed on each side of a guide-rod, C, the lower. end of which is secured to a bracket, C. This bracket is attached to the top of a pipe, D, and extends backwardly and forms the support of a toggle, b, the lower end of which is pivoted thereto 4by the pivot b', and the upper end thereof to the handle B at b. A spout, E, having a hollow boss, c, which of the pipe D', from which it receives its sup` ply of water. The pipes D and D are screwed the pipe D, is screwed fast to the topfast into the air-chamber F, which has a ange, f, by means of which it is bolted down to the platform or well-cover f. From the under side of the air-chamber F are pipes D2 and D3,
which extend in a downward direction, and
are screwed into an intermediate chamber or connection, G, on the cylinder D, through which passes the piston-rod A, having a piston, d, fitted to the cylinder D. A pipe, E', is screwed into the bottom of the connection G, and extendsdownwardly to a valve-casing, H, inclosing a valve, J, which slides freely on the piston-rod A. This valve consists of a metal cup provided with leather packing, and with deep serrations all around the top, which hook over inwardly, and thus secure in a permanent manner and at a proper distance below the top of the valve the leather packing within, so. that when the valve J strikes 0r rests against the lower end of the pipe E on the upstroke of the piston, water then rising upward readily passes through and between the serrations and into and through the connecting-pipes above, and from thence out. On stoppage of the upstroke' the valve J returns to the lower part of valvecasing H, thus stopping or relieving the strain that would otherwise be on the cylinder below, and its foot-valve and piston, and preventing the destructive force of (what is termed) the water-hammer, and so permitting the water to drain gradually from the pump. The rod A extends'through the pipe E and the valve-casing H down into the cylinder E, where a piston, I, is secured to its lower eX- tremity by means of nuts i and i', which are fitted to a screw-thread on the4 lowerv end of the piston-rod. This piston forms a hollow cylinder, open at the bottom and perforated on top, and is furnished with a valve, I', through which the water passes, the details of the top of which is secured which are shown in Fig. 10 of the drawings.
ring of leather is placed around the bottoni of ber, G, the pipes D2, D, and E', and Valve- 15 the cylinder D, between the flange (Z2 and the casing H, in combination With the Valve J, top of the connection G, whereby a Waterconsisting of a serrated metal cup having intight joint is secured between the two.
