IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 56,239, dated October 13, 18M.

To all w71 om, it may concern.:

Be it known that we, JAMES BUDD and DANIEL BUDD, both of Albany, in the county of Albany, Sta-te of New York, have invented certain new and useful Improvements in Double-Acting Pumps; and we hereby declare that the following is a full, clear. and exact description of the same, reference being had to theaccompan yin g drawings, in which- Figure 1 is a side elevation and, in part, a sectional view of our improved apparatus, the section being made through the pump-barrel and ports or channels, according to lines l 2 3 4 5 of Fig. 4. Fig. 2 is a rear elevation of the same, showing the manner of adapting the brake or pump-handle. A board is shown bolted to the rear of the pump to explain the mode in which the apparatus may be attached to a felice, wall, standard, or other support. Fig. 3 is a section on lines 6 7 3 8, through the whole apparatus, and Fig. 4L is a plan view of the same with the air-reservoir removed.

Our invention relates to that class of pumps known as double-acting pumps, in which a continuous stream of water or liquid is produeed by the intermittent action of plungers or pistons. These were heretofore most generally composed of two or more cylinders or barrels or otl two or more pistons, or were otherwise so constructed as to require much power to work them, on account of friction or velocity which the opera-tion of the numerous parts in the one case or few parts in the other involved.

The object of our invention is the production of pumps, for domestic or other uses, having but one barrel and one solid piston, yet so operating that by imparting a reciprocating movementto the piston a double action-. c., a continuous streamwill be effected, requiring for operating` it no more power than a singleacting pump giving an intermittent stream and our invention consists, first, in combining with an ordinary pump barrel, piston, and valve, ports or channels and a valve-chamber, under the arrangement for opera-tion substantially as hereinafter shown and described; second, in the arrangement relatively to the pump-barrel ot' ports or channels and a valvechamber, so that the same may be cast in one piece, substantially as hereinafter more fully shown and described; third, in operating the apparatus by means of abrake or pumphandle,

the fulcrum of which is located on top the airreservoir, substantially as hereinafter shown and described, whereby compactness of arrangement and cheapness of construction are attained.

The apparatus shown in the accompanying drawings represents a doublcactin g pump constructed in accordance with this our invention. The body of the pump is a casting consisting of a cylinder, C, from the lower end ot' which spring two ports or channels, P P', side by side, separated from each other by a partition extending throughout their whole height. Both ports are cast to or with the cylinder, but open into it at different. heights, one of them, P, above, the other, P', below the bottom D of the cylinder, thus communicating, respectively, with the interior of the cylinder and the suction-pipe. These ports or channels run in a direction nearly parallel with the cylinder, and terminate on top in a valvechamber, which, being provided with a crossdiaphram and four spherical rubber or other ball-valves, I), g, k, and z', constitutes four valvechambers, the arrangement of which is substantially as follows: rlhe valve-chambers B and G are immediately above the port P', and thus communicate directly with the suctionpipe, the latter-. c., the valve-chamber G also communicating with the interior of the cylinder by means of a channel, H. The other valve-chambers, I and K, are located over the port P, the former, I, communicating through the port directly with the interior of the cylin der, at or near its bottom, the latter, K, communicating through the channel J with the interior ofthe cylinder, at or near its top. The two ports P and P intercommunicate by means of another channel, R, also cast within the valve-chamber. The cylinder is fitted with an ordinary solid piston, whose rod r passes through a suitable stuffing, S. The pistonrod is connected by means of a link, F, with the pump-handle E, which is here shown to consist ot' a right-angular lever, the fulcrum of which is on top the air-reservoir. The connection is effected by means ot' a small bolt running through the lever and the ears L, cast to the reservoir. The air-reservoir is otherwise of ordinary construction, and is provided with the usual spout or tube, the end of which is made to penetrate the interior of the reservoir. It is attached to the valve-chamber by its base-plate M, which is so shaped as to hermetically close the chamber B G, but open into the chambers I and l. The suction-pipe is also provided with a valve, V, as usual.

The operation of the apparatus is as follows: When a reciprocating movement is imparted to the piston in the pump-barrel, a continuous stream will be produced, as by every stroke, whether up or down, the liquid will be both drawn and forced, so that there will be a constant action by suction simultaneously with a constant forcing action. rllhus when the pist0n rises a vacuum will be formed which produces suction, whereby the water is drawn up through the port 1?. The valve bein g lifted, the Water will enter the valve-chamber B, tlowing through the channel R into and through the port P, and, entering` the cylinder, will more or less fill the cylinder as the piston ascends. The same movement ot' the piston accomplishes another thing. The water which shall have been collected by a preceding downward motion is forced up through the channel H into the chamber G, thereto close the Valve g, and through the channel J (by lifting,` the valve k) in to the chamber K, from there to escape into the reservoir. rlhe downward motion of the piston removes the pressure from off the valve y, and water is drawn throu gh th e port P into the chamber G, whence it follows the piston and more or less fills the capacity of the cylinder as the piston 'recedes At the same time the water which is in the cylinder un der the piston is forced out through the port P by lifting,` the valve i into the chamber I, Which, communicating1 with the chamber B, closes its valve b. From the chamber I the water or liquid is forced into the reservoir. These operations are repeated at every stroke of the piston.

Having now fully described our invention, we shall state our claims as follows 1. The combination, With an ordinary pumpbarrel and piston, of ports or channels and a valve-chamber, under the arrangementv and for operation substantially as hereiubefore shown and described.

2. The arrangement hereinbefore described f in relation to the pump-barrel of ports or channels and a valve-chamber, so that the saine` may be cast in one piece, substantially as herein set forth.

In testimony whereof We have signed our names to this specification before two subscribing witnesses.
