FORCE-PUMP.

SPECIFICATION forming part of Letters Patent No. 395,205, dated December 25, 1888.

Application filed May 27, 1884. Serial No. 132,960. (No model.)

To @ZZ whoml it may concern:

Be it known that I, THOMAS M. BEER, of Ashland, in the county of Ashland and State of Ohio, have invented new and useful Improvements in Force-Pumps, of which the following is a description.

The abovesaid improvement relates to that class of pumps used in drill or drive wells, and which is fully described in the following speciiication, and shown in the accompanying drawings, making a part of the same, in whichM Figure l represents a transverse vertical section of the improved pump. Fig. 2 is an enlarged horizontal section through the line Fig. 3 is an enlarged detached section, a portion of which is shown as broken away.

Like letters ot' reference refer to like parts in the several views.

The pump shown in the (hawings is provided with two cylinders, A and B, connected to each other by a pipe, C, of any desirable length.

duction-pipe ln said cylinder B is a piston, F, provided with valves a o, and which is operated by the handle G, to which it is the upper cylinder will follow the lower one connected by the valve-rod H, passing upward through the cylinder A 'to the handle, as shown in the drawings.

The cylinder A alluded to consists of a shell having an interior pipe, l, forming an integral part tllereof-that is to say, the cylinder and the pipe l are cast in one piece-but which, however, may consist ot' two separate parts and united to each other in any appropriate manner. lt is preferred to have the cylinder and pipe in one piece. lt will be observed in the drawings that the pipe l has an eccentric. relation to the cylinder, thereby forming a cresceixt-shape passage, J, Fig. 2, between the interior side ot the cylinder and the pipe. An open eommunication exists between the passage J' and the pipe, as seen at K in Figs. l and 23, formed by making the pipe I shorter than the cylinder, so that a direct open relation exists between the lower cylinder, B, and the upper one and with the passage J, as indicated by the arrows. Said passage J extends to the discharging-pipe L,

In the lower end of the cylinder B l is a valve, D, for opening and closing the inand is connected thereto in any suitable way.

In this class of pumps as ordinarily constructed the cylinder A and the dischargingpipe corresponding to the passage J, above described, are two separate and distinct parts. The discharging-pipe is on the outside of the cylinder and connected thereto by an elbow and coupling. The addition of this pipe to the side of the cylinder prevents the said cylinder from following the lower one, B, into the bore of the well. Hence an enlargement of the bore at the surface of the ground must be made to receive the cylinder and the side pipe attached thereto. This enlarging of the bore or well for the purpose specified is attended often with much trouble and no little expense, as the enlargement requires curbing and a platform laid over it for protection. Furthermore, making the cylinder and the discharging-pipe in two separate parts adds to the expense oi' the pump in the manufacture thereof.

The objections above mentioned are avoided in making the cylinder and the dischargingpassage J as herein shown and described, the two being of no larger diameter through the line 0c az than the lower cylinder, B g hence into the bore of the well, thereby avoiding any enlargement of the bore for its admission therein, and 'for the reason that the cylinder' and the pipe I, `forming the passage J, are of one piece the pump is more simple `in structu re and :more readily and easily placed in position Vfor practical use.

The operation of the improved pump is substantially the same as those having the cylinder and the discharging-pipe in separate parts, and which is brieii y thus: The two cylinders A and B are inserted in the bore of the well. The passage J, as aforesaid, is connected to the discl'rarging-pipe L, projecting' Aabove the ground M, and is held in position by the brace N. On lifting the piston F to the position shown in the drawings the valve D opens and the water Hows from the well into the cylinder B. A downward stroke oi' the piston closes the valve D and forces the water through the valves a a into the pipe C, thence into the pipe l, and a portion of which IOO is forced up the passage J by the piston O in the pipe I of the cylinder, as the said piston descends con jointly with the piston l?. The Water forced up the passage J' Iills also the discharging' -pipe L and .iiows therefrom through the nozzle P. A now upward stroke of the piston opens the valve l) and closes the Valves a a. This upward action of the piston F continues the flow ol water up the passage J, the water being' forced from the pipe I and the pipe C, which have a much larger holding' capacity than the passage .I and the discharging-pipe, so that t-he excess of -water in the pipe I ,is forced up the passage J and pipe L by the upward action ot' the piston F, thereby causingr a continuous ['low 0f water from the nozzle P while working the pump.

In the ordinary pump i'or drive-wells there is an air-chamber at the upper end ot' the side pipe, a continuation oi which extends down around the discharging-pipe to facilitate the upward flow of water.

In this improved pump the air-chamber is dispensed. with, but an air-space is retained around the discharging-pipe, as shown at Q in Fig. l, which produces the same result.

Vhat I claim my invention, and desire to secure by Letters Patent, is-

ton-chamber and piston therein, an upper cylinder of even exterior diameter with the lower cylinder and located above the same, a connecting-pipe between the two, a piston-chamameter than the lower chamber and arranged in an eccentric position therein, thus leaving one of the walls of the cylinderthicker than the other, and a discharge-passage formed in` THOMAS M. BEER.
