IMPROVEMENT IN FORCE-PUMPS.
Specification forming part of Letters Patent No. 141,394, dated July 29, 1873; application filed Maren 22, 1873.
To all whom it may concern:
Be it known that I, OSCAR SNELL, ot' Williamsburg, in the county ot' Clermont and State of Ohio, have invented a new and useful Improvem ent in Pumps; and I do hereby declare the following to be a full, clear, and exact description of the same, which will enable oth ers skilled in the art to make and use the same, reference beinghad to the accompanying drawings, forming part of this specification.
This invention relates to that class of singleacting solid-plunger pumps, which are generally employed for forcing hot or cold liquids under great pressure, especially hot feed-waterinto steam-boilers, and to which latter purpose the within-described pattern will more particularly apply.
My invention consists in providing the pumphaving a single-ported sliding valve, to which a positive movement is imparted by means of a projection on the plunger acting against two adjustable tappets on the valverod-with a detachable valve-seat, which may be taken ott' and repaired, or a new one substituted without in any way impairing the efficiency' ot' the other parts of the pump.
In the accompanying drawings, similar letters of reference indicate corresponding parts.
Figure l is a vertical section of a pump embodying my improvements, the slide-valve bein gin such a position as to open communication between' the pump and suction-pipe. Fig. 2 is a section ot' the working parts ot' the pump with the valve in the reverse position to that shown in Fig. l, so as to open communication between the pump and discharge-pipe. Fig. 3 is a front elevation of the pump with the valve-chest cap and valve removed to show the ports. Figs. 4 and 5 are side and front elevations of the valve-rod and adjustable tappets. Figs. 6 and 7 are face and side sectional views of the slide-valve, showing its construction.
A represents the barrel of a feed-pump having the customary'stufing-box B and solid plunger C, the latter being driven by the pitman D, which is connected to the wrist c of the driving-shaft E. Projecting from one side ofthe pump-barrel is a chest, F, which contains a slide-valve, G, whose rod, g,is operated by the projection H on the plunger O striking on the tappets K Kf. N, Figs. l and 2, represents the detachable valve-seat with two ports, I I. The seat is secured in place by means of the bolts which secure the Valvechest to the barrel. The seat is made, preferably, of hardened steel, and the part upon which the valve slides is raised above the common surface, and in length is shorter than the length and stroke of the valve, in order that the wear may be evenly distributed to prevent concavin g. Thevalve G covers two ports, I 1', the upper one of which, I', communicates with the suction-pipe J, While the lower one, I, leads into the pump-barrel A. The shaft E may be driven by any known means.
rIhe pump is operated as follows: When the piston C is beginning to ascend, as shown in Fig. l, the valve G is in-such a position as to cover both of the ports I I, and water consequently flows up the suction-pipe J, and through said ports I I, into the pump-barrel A, which now continues during the ascent ot' the piston. During the time in which the piston is completing its upward stroke the projection H, on its side, collides with the upper tappet K, and instantly reverses the position ofthe valve G, as shown in Fig. 2, which permits of the contents of the pump being discharged, through the port I, valve-chest F, and pipe L, into the boiler. Thus, during the time in whichthe piston is completing its downward stroke, the projection H, on its side, collides with the lower tappet K', and reverses the position of the valve, as shown in Fig. l, ready for the ascent otl the piston. It will be seen that, the valve being changed at the termination of each stroke ready for the ascent or descent ot' the piston, and as the requisite movement given is a positive one the pump is certain of being tilled and emptied at every alternate stroke, and there is no danger of the pump becoming inoperative on account ofthe accumulation of steam Within it.
What I claim as new, and wish to secure by Letters Patent, is, viz: v
In combination with the pump proper, A, the detachable valve-seat N, substantially as shown and described.
OSCAR SNELL.
