cation.

My invention relates to an improvement in pumps; and it consistsin the peculiar construe`4 tion and combination of devices, that will be more fully set forth hereinafter, and particun larly pointed out in the claims.

In the accompanying drawings, Figure l is.

a vertical sectional view of a pump embodying my improvement. Fig. 2 is a detached enlarged section showing more clearly the construction ofthe plunger and the packing; and Fig. 3 is a horizontal section on theline x Fig. 2.

A represents the pumpcylinder, which is provided at its lower end with a head or casting, B, in which is a semicircular channel, C, which communicates with the lower end of the pump-cylinder, and a curved channel,D,which is concentricv with the channel O, communi Cates at its upper end with the lower end of the pump-cylinder, and communicates at its lower end with t-he upper end of a suctionpipe, E.

F represents a perforated plate, which is arranged in the bottom 'of the pumpcylinder and forms a seat for an upwardlyopening check-valve, G, that is arranged at the upper end ofthe channel D.

H represents a pipe, which extends from the upper end of the pump-cylinder and has its upper end closed by a cap, I.

L represents a piston or plunger, which comprises a metallic disk, M, having a boss or offset, N, in its center on its upper side. rIhe said boss or offset is provided in its lower side with a circular recess, O, with the upper end of which communicates a channel, l?.

R represents a packing of leather or other suitable material, which is arranged under the disk M at a suitable distance below the same,

and is provided on its upper side with astud, S, that its in the recess O. Down through the center of this stud, and through the center of the packing R, extends a channel, T, and cham nels U are made in the sides of the stud S, as shown, which channels communicate with the upper end of the recess O, and with the space M between the disk M and the packing R.

V represents a check Valve, which is arranged on the upper side of the stud R, and is adapted to open and close the channel I. From the upper side of the piston extends a rod, W, which passes up through the pipe H and through a central opening in the cap I, as shown.

X represents a vertical pipe, which is arranged on one side of the pump-cylinder, has its lower end coupled to the head B, com municating with the channel C, and provlded with the upwardly-opening check-valve Y, and has its upper end connected to an air-chamber,

Z, which is arranged on a base, A', the said base being provided with a central opening, through which the pipe H extends, and also provided with a channel or chamber, .13', communicating with thelower end of the air-chamber Z, and from which extends a delivery-pipe, C, provided at its upper end with a goose-neck spout, D', and a stop-cock, E.

F represents a cap, which closes the upper end of the airchamber Z, is provided on one side with an arm, G', to which the upper end of the pipe -H is attached, and is provided `on its opposite side with an outwardly-extending arm, H. i

I represents a link, which has its lower end pivotally connected to the arm H and has its upper end pivotally connected to a sockettube, K.

L represents a joint,which connects the upper end of the pump-rod W to the socket tube K.

Mrepresents a pump-handle, which has its inner end curved, as shown, and its outer end straight for a considerable distance and extending through a socket-tube, K, longitudinally adjustable thereto,and secured to said sockettube by means of set-screws N. On the outer portion of the handle M is secured an adjustable counterbalancing-weight,O,which is provided with a set-screw, P', by means of which it may be secured at any desired point on the pump-handle.

From the foregoing description it will be IOO readily understood that by operating the pumphandle the piston or plunger may be caused to reciprocate vertically in the pump-cylinder A. On the upstroke of the said piston or plunger the valve G maybe opened, so as to cause water to be drawn upward through the pipe E and the channel D into the cylinder,and the valve Vwill be closed. On the ensuing downstroke 'of the piston or plunger the valve G will be closed and the water in the lower portion of the cylinder forced through the channel G past the valveY into the pipe X, a small portion of the water passing upward through the channel P and past the valve Vahove the piston or plunger, so as to causea small quantity of water to accumulate above the piston or plunger and nd its way downward through the channels U into the space M' and the packing It, so as to keep the latter lubricated and prevent the same from getting dry and out of order. After the pump has been operated a short time a sufficient quantity of water has become accumulated in the chamber Z to create considerable pressure, and thereby, when the stop-cock E' is opened, the water will be discharged from the spout in a continuous stream.

R represents a pipe, which communicates with the pipe X near the lower end thereof, and is provided with a stop-cock, S,which is operated by means of a rod, T.

U'represent-s an air-chamber,which com municates with the pipe R'.

V' and W represent delivery-pipes, which also communicate with the pipe R'.

X' represents a cylinder, which communicates, near its upper end,with the pipe X. In this cylinder is arranged a piston, Z',which is adapted to be forced downward by the pressure of the water in the pipe X and cylinder X', and is adapted for the attachment of connections (uot shown) for the operating-rod of a windmill or other motor, so that the same will be thrown out of gear and caused to cease to operate when a sufficient pressure is accumulated in the chamber Z and the pipe X to cause the piston to descend.

After the pump has been operated sufficiently to create the requisite degree of pressure in the chamber Z,thestopcock S' is opened and water is forced through the pipe R' into the compressing-chamber U', and is accumulated therein under pressure. The stop-cock S' is then closed, thus maintaining the water under pressure in the chamber U',and by opening the stop cocks in the pipes V' and Wwater will be caused to iiow from the said compression-chamber U' in a continuous stream.

Having thus described my invention, I claim- 1. In a pump, the combination of the cylinder having the check-valve in its lower side and the outletchannel C,the plunger arranged in the said cylinder and having the recess O and the channel P communicating therewith, the packing R, arranged below the said plunger, and having the stud S extending into the said recess and provided with the channel T, communicating with the channelsPandO,and the check-valve V in the upper end of the channel T, substantially as described.

A2. In a force-pump, the combination of the cylinder, the plunger therein, the packing below the said plunger and at a suitable distance therefrom, so as to leave a space, M', the channel communicating with the lower end of the cylinder and with the space between the plunger and packing, and the valve V, arranged in one of said channels, substantially as described.

3. The combination,in a pulnp,of the pumprod, the socket-tube connected thereto, the link connecting the said socket-tube to afixed point, the handle M', extending through the said socket-tube and adjustable longitudinally therein, and the counterbalancing-weight O', adjustable on the outer end of the said handle, substantially as described.

4. In a pump, the combination, with the plunger, the packing R below the same and at a suitable distance therefrom, so as to leave a space, M', the recess O in the plunger, the hollow stud S, extending from the packing and fitting in the recess O, the valve V, the channel P, and the channel U, communicating with the space M', as set forth.

5. In combination with the cylinder A, the pipe H, rising therefrom, the pump-rod W, passing through the pipe, the air-chamber Z',

the cap I1" for the chamber, having arm G' to roo connect with the pipe H, the link I', pivoted to the cap, the socket-tube K', pivoted to the pump-rod, and also to the link l', as set forth.

In testimony that Iclaim the foregoing as my own I have hereto affixed my signature in 105 presence of two witnesses.
