IMPROVEMENT IN PUM'PS.

,The Schedule referfed to in these Lettera Patent and making part.of the same.

To all whom. 'it may concern:

Be it known that I, J Jsoon O.'JoYon, ot' tbe cityof Dayton, in the county of Montgomery, and State of Ohio, have invented certain new and useful Improvements in Pumps; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l represents a vertical cross-section of the valve-chamber;

Figure-2, a vertical longitudinal section; and

Figure 3, a horizontal section on line V U.

Like letters refer to the same parts in all of the gures.'

My invention relates to( double or continuously-acting force-pumps, and consists in a novel arrangement of the chambers, passages, and valves, and in placing the piston in the air-chamber, and the valves at one side thereof, and in the'se'veral combinations hereinafterpset forth `and claimedas new.

To. enable others skilled in the art to make and 'use my improved pump.v I will describe its constructio'and operation.

I make the principal portion, or frame-work, of my pump, A, the air-chamber. As shown, it is madein form of a barrel. Into this barrel or chamber, I insert the discharge-pipe G, 'which reaches nearly to the bottom thereof, so as to make it operate as an :tn-chamber. It is inserted one side of the centre or middle. In the centre, I place the piston-chamber or cylinder B, which passes down to the bed-plate H, and is connected with or attached to it. On one side of this piston-cylinder I cast, or otherwise attach, a tube-paiiiton or cylinder, E, which opens into the piston-chamber near the top, and also passes down to plate or bed H. Incylinder or chamber B, I place the piston or plunger D, which is suitably packed, and is operated by the rod C. The bed or bottom H covers the bottom of the barrel A, and alsoextends out at the side, andV forms the lower half of the valve-chamber. It is also made of suicient depth to contain the passages from the valves t0 the air-chamber or plunger, the partitionplate W, and the bottom plate I, being cast with H.

The space between plates Hand I- is divided into two equal or nearly equal parts bythe partition-plate W, which leaves two passages, U and V. This plate, W, is simply a partition from the piston-cylinder to the valve-chamber, as shown by the dotted lines in fig. 3. From that point out, at H", it is double, with side inc lines, as shown in g. 1. These inclined sides form a chamber, x, between them for the entrance of water, which enters, at the opening T, into chamber z, and passes through the openings or passages P or'P',-ac cording to the stroke of the pump. These passages, P1 P', are closed by the action of the valves Nl and N. These valves,.N, are made to rock on the lower edges as shown, or they may rest on pivots b b, if desired, and in order to insure their action upon the return-stroke,

Vand prevent them from turning too far, small pins, a,

are attachedneartheir upper edges, which strike against the walls before the valves reach a vertical position,

so that they will always fall into the proper position, and they are held down by the stopd, yor by other suitable meaus. Above these valves, I place the .doubleacting valve M, which rocks in plate L, or may be supported at the ends like the valves N. The plate L is attached to or cast with plates K, and on each side is provided with openings, O, which are so arranged with valve M, that when one is closed the other will be opened. The passage Q opens up between plates K, and-may also open out, at the inner end, into the discharge-passage R, or open up and out botha The curvedplate J is bolted on above the plates K, as shown at iig. -1, \vl1ich leaves between 'them the chamber or discharge-passage It. The air-chamber A and bed or plate H are fastened by bolts passing through the ilanches, as are also plates S and H, aud S and J. The other plates and partitions I usually cast in, As the pump is made of cast-iron, or other suitable metal, 'water may b'e admitted directly through the hole or opening T, but I usually place the pump above the well-cistern or reservoir, and screw in, or otherwise attach, a pipe to this opening, and extend such pipe down into the water, so that, so far as the first or principal elevation of water is concerned, the pump is a suction-pump, and from the point of entrance into the pump out of it, a force-pump, which makes it, in its usual action, a combined suction and force pump.

In operation, the piston or plunger-rod O is operated by a lever, or crank, or by any other suitable means. Two strokes will lill the pump with water. An up stroke of the piston will then draw the water through valve N', passage U, up into the cylinder B, and will force the water in the upper portion of B, out through E', down through pipe E, opening F, passage V, openings O and Q, into passage It, and through R into the airchamberA, and from that into discharge-pipe C, from which it is discharged with great force. A down stroke operates the same way, simply changing the sides of the operation. All of the joints which are to be tight, and the valves, are to be properly packed to Yprevent leakage. This construction makes a powerful pump, as I have found from testing it.

Having thus fully described my pump,

What I claim as new, and desire to secure by Le ters Patent, is v 1. The combination and arrangement of the valves N 'N' and M with the openings U, V, and R, substantially as and for the purposes specified 2. The combination and arrangement of the pistonchamber B, piston or plunger D, tube or cylinder E, and discharge-pipe G, with the flues or. passages R, U, and V, substantially as specified.

3. The combination and arrangement of the airchamber A., piston-cylinder B, piston or plunger D, tiibe or passage E, and pipe G, with the passages R, U, andV, valves N N and M, with their openings T, substantially as and for therpurposes specified,
