FORCE-PUMP.
SPECIFICATION forming part of Letters Patent No. 363,721, dated May 24, 1887.
Application filed August 2l, i896. Serial No. 211,530. (No model.)
To all whom, it may/concern.-
Be it known that I, MICHAEL S. BREWER, a citizen of the United States, residing at St. James, in the county of Phelps' and State of Missouri, have invented certain new and useful Improvements in Force-Pumps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,forming part ofthisspeciiication,and in wl1icl1 Figure l illustrates a vertical section of a well, showing my improved pump in side elevation. Fig. 2 is a detail view showing the frost-valve in its closed position and the piston-rod elevated. Fig. 3 is a similar view showing the piston-rod in its lower position. Fig. 4 is a section taken on line 4L 4, Fig. 2, showing the frost-valve and a. section of the lifting-spring pressing on the valve. Fig. 5is
,an enlarged section .of the pu nip-cylinder and the piston down andshown in sideview. Fig. G is an enlarged section of the cylinder and piston shown. Fig. 7 illustrates a modification.
My invention relates t0 that class of forcepumps with submerged cylinders and tubular pistons; and my invention consists in features of novelty, hereinafter fully described, and pointed out in the claims.
Referring to the drawings, A 'represents a well in which one of my pumps is located.
B is the cylinder of the pump, which rests on a foot-block, and C is the conical plungerhead that operates in the cylinder.
D is the guide-frame securely bolted to the cylinder at D', and is provided with a collar, D2, above,to guide the piston-rod asit works.
E represents the drop or drag braces that are hinged to the cylinder at E.
F represents the pist-on rod, and F the spout, which is secured to the rod by acoupling, F2.
G is the treadle attached to the piston-rod at a suitable distance above the platform to be convenient for the operator who pumps the water, and by which he forces the piston down.
H is a coil-spring secured to a lug, H', on a collar, H2, that surrounds the piston-rod immediately below the platform, to which latter it is secured. attached to a collar, H3, that also surrounds The lower end of this coil-spring is.
the piston-rod, and is adjustably secured thereto by set-screws I'I", that work through the collar., The function of the coil-spring is to elevate the tubular piston on its returnstroke.
It will be seen that the piston C consists of a'hollowIrusto-conieal shell,which is provided at its apex with a perforation for allowing communication between the interior of the cylinder B and the interior of the hollow piston-rod F,
to which it is connected through the medium ing, the body of which is cylindrical and provided on its exterior with screw-threads for engaging corresponding threads formed on the interior of an annular hub, C', cast integrally with the {ruste-conical piston C and surrounding the apertures c. I am thus enabled not only to make the piston much cheaper than when made solid and bored out to form valvechambers, but Ir am also enabled to make it much lighter, which is quite a desideratum in pumps of this character. Furthermore, by forming the upper side of the piston of conical shape, the resistance which the water offers to its ascent is lessened.
The water in the latter action of t-he plunger is forced up, within the conical head and through a ball-valve chamber, J, at the foot of the piston-rod and passes up the tube, being prevented from return to the cylinder as the piston again descends by the ball J descend ing to its seat in the chamber.
The cylinder and plunger-head may be made of porcelain, stoneware, or other imperishalole material, and the other partsl of any suitable material for the functions they have to perform.
An automatic frost valve or pin, K, acts in connection with a vent-hole, K', in the tube, and is attached to and supported by a springrod, K, that is secured to the collar H3, that supports the coil-spring H, by a set-screw, K3,
ICO
tubular pistonrod is then screwed into its collar immediately above the ball-valve chamber that surmounts the apex of the plunger-head. The cylinder, with its attached parts, is then submerged in the well, the hemispheric footblock B', attached to the bottom of the cylinder, finding a footing even when the bottom of the Well is uneven. The pivoted braces that are hinged to the top of the cylinder follow on downthe well as the cylinder descends and firmly brace it both laterally and from being elevated. The lifting coil-spring and frostpinvmay be now secured to the pistonrod by the attachment of the collars that command it, the treadle next placed in position, and the spout screwed into its collar, and when the platform is down the pump is ready to work. Vhen the cylinder with its attached parts is submerged, the liquid is lifted by the direct action thereon ofthe tubular piston-rod instead ofby suction. The tube conveying the water forms the connectingrod between the piston on the one hand for forcing down and the liftingspring for elevating.
It will be seen that as the piston works and the coil-spring expands longitudinally it contracts laterally and at the same time rides upon the shoulders'I5 ofthe frost-pin rodand forces it into the vent-hole in the tube, thus automatically forcing the frost-pin into its seat when the pump is in motion; but when the coil-spring again relaxes its hold when the pump is idle, the spring that carries the pin extracts it from the vent and the water escapes, not only removing all danger from frost,l but also in summer the water is not heated in t-he pipe, as it is not confined in the metal tube above the platform.
It is frequently made an objection to frostvents that they greatly increase the labor of pumping, so that frequently in early winter the frost-pin is neglected to be pulled out until some night a hard frost comes and the pipe bursts. All danger ofsuch accidents is avoided. by my automatic frost-p'in.
In Fig. 7 I have shown a modification of the means for raising or lifting the piston and piston-rod to be used in place of the spring H. This consists of a weight, O,.connected by a cord or chain, O, to the collar H, the cord or chain passing over a pulley, O2. It will be thus seen that when the piston is forced down the Weight will act to lift the piston and rod. In this figure I have also shown a modication of the means for opening the vent,whi ch consists of a cam, O3, located at top of the Well, which is engaged by an incline, N, on the upper end of the spring H, upon which the vent is formed. I have shown this cani formed upon the collar H, that supports the pulley O2.
I am aware that it has been proposed to make the top sides of pistons slightly curved instead of dat; but I am not aware that it has ever been proposed to give them a decidedly conical shape for the purpose of lessening the resistance which the water offers to their ascent. Y
I claim as my invention-M 1. In a pump, the combination of the stationary cylinder B, open at top, the piston C, working in said cylinder and provided with an opening, an outwardly-seated valve for permitting the ingress of iiuid to said cylinder, but preventing its egress, a vertically-movable hollow piston-rod secured to said piston and communicating with said cylinder, and a valve for permitting fluid to enter and pass upward through said hollow rod on the descent of the piston, but preventing said fluid from flowing downward and back into the cylinder, substantially as set forth.
2. In a pump, the combinatiomwith the cylinder, of a piston fitted therein and having a suitable port therethrough, a valve-casing secured to the piston so as to surround said port and be removable from the outside ofthe piston, said casing being provided with an opening for the passage of water, and a valve-seat surrounding said opening, and a valve placed within the casing and adapted to prevent the water passing the piston by closing against the seat formed on the valve-casing, substantially as set forth.
8. The combination of the cylinder B, the hollow frustol conical piston G, having the outlet aperture at its apex, the inlet-apertures c in its top side, and the annular hubs C', surrounding said apcrlures c, the valve-casings I, secured to said hubs C and having the apertures z', the valves I', the valve-chamber J, secured to the apex of the said piston, the valve J, and the hollow piston-rod F, all constructed and arranged to operate substantially as set forth.
