IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 150,544, dated May 5, 1874; Reissue No. 8,243, dated May 21, 1878; application filed December 19, 1877.

To all whom it may concern:

Be it known that I, THOMAS DOWLING, of Gloucester, Essex county, Massachusetts, have invented certain Improvements in Pumps and that the same are fully described in the following specification and illustrated in the accompanying drawing.

My invention consists in the devices and combination of devices set forth in the several claims.

In the drawing, Figure 1 is a side elevation of a pump embodying my improvements. Fig. 2 is a vertical section taken through the spout;

and Fig. 3, a similar view on a plane at right angles to that of Fig. 2. Figs. 4 and 5 show the pump-handle in difierent positions, while Fig. 6 is a vertical section through the parts with the spindle.

In the several figures, A denotes the pumpbarrel, and B the spout, having the two discharge-orifices a 12. Between these orifices is a valve-seat, d, which serves, in connection with a valve, 0, to close the passage to the lower or outer orifice a and divert the liquid elevated by the pump so that it shall be forced out of the orifice b, or up through a pipe leading therefrom. As shown in Fig. 2, the valve 0, faced with a thin packing-ring, is closed upon itsseat d by compression effected by a screw so that the operator may force the valve on or off its seat. I thus produce, without expensive fitting, a durable and effective valve, not liable to wear in its bearings. A screw plug or cap may be employed to close the orifice b when not in use.

A peculiar feature of my invention is the rotary air-chamber G, to which the pump-handle is attached, and which is so mounted upon the top of the pump-barrel as to enable the airchamber to be turned around upon its seat and clamped thereto, in order to adjust the pumphandle in any desired position relatively to the spout. The manner in which I have chosen to illustrate this part of my invention is representedinFigs. 1, 2, and3. The upperend of the barrel has a circular lip, e, forming part of a socketed head, D, within which is a packingring, or, upon which the lower edge of the airchamber rests, and against which it is forced by screw-rods f and nuts 9. These rods hook upon the lip e, and extend up through ears h projecting from the air-chamber, and by this means the chamber (land barrel A are united in such a manner that the one may be readily turned upon the other. Thus the position of the handle, which is mounted upon the air-chamber, may be varied with relation to the spout as occasion may require.

The handle E (shown in several of the figgures) is originalin construction. It consists of a tubular body, z, a head, 70, and arms l m, the former projecting inwardly from the inner end of the body i, and the latteroutwardly from the head k. This handle oscillates upon a spindle, F, passing through the tubular body 2', and supported by the opposite sides of a hollow projection, G, forming part of the airchamber. The peculiar construction of the pump-handle enables it to be readily inserted in and withdrawn from the extension G, or the hole in one side thereof, as occasion may re quire. I shape the long arm m of the handle, as shown in Figs. 1, 3, and 5, so as to bring its outer end into the same vertical plane as the arm I. The spindle F is provided with a shoulder, 1", and at the end with a screw, 12, to receive a nut, 0, and leather washers are interposed upon the spindle and the bodyi at points 19 s t, so as to make tight joints when the nut 0 is screwed up. Thus the chamber 0 becomes an air-tight reservoir, since the packing-ring a, between the chamber and barrel A precludes the admission of air at that point, and the washers perform alike service at the junction of the handle with the extension G, so that air can pass to and from the chamber 0 only through the barrel or spout.

A peculiarity of the spindle remains to be described. Beyond the shoulder r the spindle is prolonged, and formed with a leg, u, to extend into either of two socketed studs, o w, projected from the side of the extension G, one being above and the other below the spindle. A helical spring, '0, wound around the spindle, and having one end fixed thereto and the other to the handle, or to a stud, w, extending therefrom, serves to force downward the longer arm of the handle, and to aid the handle in lifting the piston. By turning the spindle around and setting it in one or the other of the socketed, studs, the spring canbe taken up or let out,

1. A pump-barrel bearing a spout and having a suitable'paeking-rin g at its upper end, in combination with an air-chamber resting byits lower edge on saidpaoking, adjustable thereon by rotation, and bearin g the pump-handle, said parts being united by vertical clamping-bolts for securing a tight joint, substantially as set forth.

2. A pump-barrel and a spout therefor, havin g two discharge-orifices, as described, and a valve-seat between said orifices, in combination with a valve adapted by compressionto direct the flow of water to either orifice, substantially asset forth.

3. A pump-barrel bearing a spout and provided with an outwardly-projecting flange, in combinationwith an vadjustable rotary air chamber of greater internal diameter than the barrel, so as to permit free play and convenient connection of tlie piston-rod and lever-arm within the air-chamber, substantially as set forth.

4. The pump-handleE, composed of the tubular body-i, having a suitable fulcrum, and two arms, .l on, the. latter being formed with an offset to bring its lower part in line with the arm l, substantially as set forth.

5. The combination, wit-h a pumphandle, of the spindle F, having screw n and nut o, and also formed with the leg u, for insertion in either of the sockets v w, substantially as set forth.

.6. The combination of the spring 4) with a pump-handle and its supporting -spindle F, formed with the leg u, adapted to engage with the studs 1) 10, substantially as set forth.
