IMPROVEMENT INDOUBLE-ACTING FORCE-PUMPS.
Specification formingpart of Letters Patent No. 178,057, dated May 30, 1876; application filed April 10, 1876.
To all whom it may concern:
Be it known that I, GEORGE W. HOOPER, of Greene, in the countyof Androscoggin and State of Maine, have invented a new and useful Improvement in Double-Acting Force: Pump, of which the following is a specification:
Figure 1 is a side view of my improved pump, partly in section, through the line at w, Fig.2. Fig. 2 is a horizontal section of the same, taken through the line 3 3 Fig. 1.
Similar letters of reference indicate corresponding parts The object of this invention is to furnish an improved double-acting force-pump, simple in construction, convenient in use, easily .operated, and effective in operation, throwing a steady stream.
The invention will first be described in connection with drawing, and then pointed out in the claims.
.Ais the pump-cylinder, to the ends of which are bolted the heads (B, and within which works the piston C. The piston C is cast solid, and is made with parallel ring-flanges, which project nearly to the inner surface of the cylinder A, and which form a square groove around the convex face of the piston to receive the packing D. The packing D is made of strips of leather'bent edgewise into thegroove of the piston O, enough pieces of leather being used to fill said groove snugly. When the packing D become. worn it may be M renewed by taking 0E one of the heads B, and
removing the piston O. The piston-rod E passes out through a hole in the upper head B, which hole is made larger than the pistonrod E, to give it the necessary. lateral play. F is a plate of steel, or other hard metal, having a hole formed through ,it, into which the piston-rod E fits snugly. The plateFis smaller than the cavity in which it is placed, so that it may be moved laterally by the lateral movement of the piston-rod E. The plate F is kept in place by a ring-plate, Gr, which is bolted to the head B, and rests upon a shoulder of said head, which shoulder is made a little higher than the thickness of the packing-plate F, so that it cannotbind the said plate F. To the upper end of the piston-rod E is attached a cross-head, H, to the ends of which are pivoted two small rollers, I, which roll along grooves in the-inner sides of the guide-bars J. The guide-bars J are parallel with each other, and are pivoted to the ends of two parallel bars, K, which are pivoted at their centers to the pumptube L, so that by turning the bars K upon their pivots the guide-bars J may be adjusted closer together or farther apart, and Will be held all the time parallel with each other. To the cross-head H is pivoted the lower end of the connecting-bar M, the upper end of which is pivoted to the head of a bolt, N, that passes through the end of the pumphandle 0, and is secured to it by a nut. The handle 0, at a little distance from the bolt N, is slotted longitudinally to receive the fulcrumbolt P, the head of which is pivoted to an arm, Q, attached to the pump tube L. By this construction the fulcrum-point of the handle 0 may be adjusted by adjusting the bolt P in the slot of the said handle 0. To the side of the cylinder A is attached, or upon it is formed, a valve-box, R, from the ends of which openings S S lead into the end parts of the cylinder A,and openings T T leading into the bore of the pump-tube L. In the box R is cast a twisted partition, U, forming two passages, VV,--the one, V, leadingfrom the opening S,leading into the cylinder A, to the opening T, leading into the pump-tube L, and the other, V, leading from the opening T, leading into the pump-tube L, to the opening S, leading into the cylinder A. W W are two valves interposed between the openings S S and the openings T Tthe one, W, opening toward the opening T, and the other, W, opening toward the opening S. X X are two valves interposed between the openings S S and the passages V Vthe one, X, opening toward the opening S, and the other, X, opening toward the passage V. As it is advisable that the piston-rod E should'be close to the pump-tube L, the cylinder A is let into said tube L, where it is secured in place by rods Y, bent to fit upon the pump-tube L, and the ends of which are secured to flanges formed upon the cylinder A and box R. The rods Y keep the cylinder A and box it in place, and at the same time they strengthen the pump-tube L where it is weakened by letting the said cylinder into it. The bore of the tube Lis closed by a plug, 1 driven into a hole formed in said tube between the'openings T T, and made a little The water enters thev opening T from the lower part of the tube L, and may enter the said tube through an openlarger than said bore.
ing between the plug Z and opening T, or at any desired dis'tance below said opening T.
In using the pump, as the piston 0 moves downward a vacuum is formed above it, and
the water is forced by atmospheric pressure in through the opening T, up through the passage V, forces open the valve X, and passes through the openings into the upper part of the cylinder A. At the same time the water in the lower part of the cylinder A is forced out through the openings, forces open the valve X, passes up through the passage V, through the opening '1, into the'pump-tube L, and out through it. As-the piston 0 moves upward the water passes in through the opening T, opens the valve W, and passes in shown and described.
K with the grooved guide-bars J, the rollers I, and the cross-head H, attached to the piston-rod E of a pump, substantially as herein GEORGE W. HOOPER.
