PUMP.'

SPECIFICATION forming part of Letters Patent No. 237,240, dated February 1, 1881.

Y Application filed November 2,1880. (No model.)

To all @L1/wm it may concern Be it known that I, BENJAMIN BRANsoN, a citizen ofthe United States, residing in Philadelphia, Pennsylvania, have invented Vcertain Improvements in VVVell-Pumps, of which the following is a specification.

My invention relates to the construct-ion of well-pumps in which wrought-iron tubular rods constitute part of' the frame; and the object of my invention is to construct a substantial, light, and economical pump ot' this character, and to combine therewith a vacuum-chamber cheaply constructed in the manner explained hereinafter.

In the accompanying drawings, Figure l is a vertical section ot' myim proved pump; Fig. 2, a sectional plan on the line l 2; Fig. 3, a sectional plan on the line 3 et; Fig. 4, a sectional plan on the line 5 6, and Figs. 5 and 6 views illustrating modifications of my invention.

The portion A ot' the pump, which is generally above ground, and which is termed the stock, consists of the plate a, secured to a suitable foundation, four wrought-iron tubes, b, b', b2, and b3, and the top plates, c, carrying the bracket e, to which the handle B is pivoted. These rods may be screwed into the foundation-plate a and into the upper plate, c,- but I prefer to screw the two rods b b(shown in Fig. l) to the base-plate, and let them pass freely through the upper plate, above which they are furnished with nuts, the other tubes, b2 and b3, simply fitting into sockets in the upper and lower plates, and being secured therein by tightening the nuts of the rods b b. By this mode of construction a light, and at the same time substantial, stock is obtained.

The main pump-barrel D is suspended within the well by means ot' two tubular rods, dd', the Aattachment of these rods to the plate aand pump-barrel being made in any manner which may be deemed most convenient and economical, but so that the rod d. shall communicate with the rod 11,'the two rods constituting the force-pipe, having its outlet at the spout h. The two rods d and b may also communicate with each other, but this is not absolutely essential.

It may be remarked here that the tubular vthe pump-barrel; or the rod may have any vother direct communication with the suctionpipe below t-he suction-valve m.

It is well known to those familiar with pumps that a chamber communicating with a suction-pipe, but otherwise closed, contributes to the easy working ot' the pump; hence such chambers are frequently applied'A to rapidlyworking steam-pumps, andare termed vacuum chambers!! In my improvements this chamber is economically formed, partly by the tube d and partly by the passage t' i forming the communication between the said tube and the suction-pipe; and if a chamber of large capacity is desired, the interior ot' the tubular rod b' may form an extension of the vacuumchamber,

The suction or foot valve 'm may be of the ordinary construction, as also may be the bucket or piston a, which, in the present instance, is connected to a tubular pump-rod, G, theinterior of which constitutes the air-chamber, and the upper end of which is ljoined to the short arm of the pump-handle B. n A supplementary barrel, H, projects above vand communicates with the main barrel, and

to this supplementary barrel is adapted a piston secured to the tubular pump-rod. It should be understood, however, that neither the valve, buckets, supplementary barrel, nor tubular pump-rod, serving as an air-chamber, constitute any part of my present invention.

A substantial pump-stock may consist of three tubular rods, arranged as shown in Fig. 6,-one of these rods serving as the dischargepipe, and one of the other rods serving as part Vof the vacuum-chamber.

`plate,o, having a bearin g for the pump-handle,

IOO

are combined with tubular Wrought-iron rods, forming,vwith said plates a and c, the stock of the pump, all substantially as set forth.

2. A pump in which a barrel, D, and plates aand 0 are combined with tubular Wroughtiron rods, which serve to connect the said barrel and plates together, substantially as described.

3. The combination of the base-plate a, the top plate, c, the rods b2 b3, adapted to sockets in said plates, and the rods b and b', serving to clamp the plates ci and 0 together and ooniine the rods b2 and Z13, the rod b forming an extension of the discharge-pipe of the pump, all substantially as set forth.

4. The combination of the base-plate ct, the pump-barrel D, and suction-pipe E with va tubular supporting-rod forming a vacuumA chamber, or part thereof, communicatingwithl the suction-pipe below the suction-valve m, all zo substantially as set forth.

5. The combination of the suction-pipe E of the pump, the pump-barrel D, having an extension inclosing a passage, z', and the coupling x, having a passage, i', leading from the 2 5 passage i to the suction-pipe, as set forth.

In testimony whereof I have signed myname to this specification in the presence of two subscribing witnesses.

BENJAMIN BRANSON.
