VALVE F011 PUMPS.
GUSTAVUS HAMMER, CINCINNATI, OHIO. i.
PUMP-VALvE.
Specification of Letters Patent No.` 12,413, dated February 20, 1855.
'To all whom z' may concern.' v
Be it v'known that I, GUsTAvUS HAMMER, .of the city of Cincinnati, in the county of :Hamilton and State of Ohio, have invented a new and useful Improvement in Valves for Pumps; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accomp'anying drawings and tothe letters and gures of reference marked thereon. v
`My'inventionconsists in an improvement inthe connection of the induction and educ- -tion valves, belonging to the cylindrical Valve-box and valves, for pump patented by I. R.' Bassett of Cincinnati. The manner he employs, of connecting his inducting and l educting valves tothe cylindrical valveb0x,
consists in attaching them all to one and thel same spindle, or stem, which works in the center of the cylindrical box, andthe valves lin their' movements must all worktogether,
both the two inducting and educting valves, the pump being double acting. Now, by this arrangement of "valves, it is impossible for; them all to be closed at one and the samel time, and therefore if the pump'is stopped? in its operation, and is not provided withl a check-valve, the water will-run-out of one i l end of the pump, which, on commencing to work the pump again, will require a stroke or two to exhaust the air, (which is labor lost) before'the water can again be brought into the pump. And in this arrangement of valves, every time the piston changes its stroke, some of the water is lost, owing to the motion of all the valves being connected together whereas, if each set of valves worked alone and separate, as soon as the piston had terminated its stroke, it would instantly close and retain all thewater that had been drawn into it. When the valves are all attached together on one and the same stem, stationary, as in the case of Basset-ts, it will be perceived that all of them must be opened at one and the same time, for a moment, at each change in the stroke of the piston of the pump, which admits the water running out of the end of the pump that had been previously drawn in, and be redrawn again at the opposite end. In using the Bassett valves and box, there must be a check-valve always attached in order to make it work.
The improvement I have made, does away with the necessity of using the check-valve altogether; but it may be used if desired.
My improvement is an effectual remedy for all 4the faults of having, the valves -attached together on one and the same stem or spindle, which is effected in the manner I employ, of attaching the inducting valves of one end of the pump to the educting A valves of the opposite end of the pump, vin such a manner, that the instant the inducting valve of o-ne end ofthe pump closes, it
will close the educting valve of the opposite end; or, the instant it opens, the other will y open also-which is the way that the valves of all well regulated double-acting pumps should work, that is, yas ythe inducting val-ves of one end ofthe pump, open, the educting valves of its opposite end should close...r And v by having each set of valves so attached, all of them can be closed at one andtheVL same time, and thereby retain the water `that has been drawnin the pump, when .its operation isstopped, and .which dispenses with the necessity of using the ordinary check-valve, as isrequired in the other case.
To enable others, skilled in the art, to make and use my improvement, I willproceed to describe its construction vand operation, by reference to the accompanying drawings, forming part of this specification.
Figure 1, is a sectional elevation through the airechamber, valve-seat and barrel of a pump, to which the improved valves are attached.
Fig. 2, is a sectional elevation through the barrel, showing the opening that runs to the top of the pump that is connected with the valve.
Fig. 3 is a horizontal sectional view through the valve chamber, and openings to the barrel of the pump. This portion of the pump is made of cast-iron, as usual, or other material, if desired, and presents nothing new or novel. a, a, represents the barrel of the pump. B the piston rod, provided with the piston c, c. The pump is double acting, and is provided with a water passage cZ, d, that leads from the valve to the `top of the pump. e, e, is an air-chamber,
box with the improved valves attached, in an opened state. Fig. 5 is the top of the box, showing the eduction openings. Fig. 6, is a sect-ional View of the box (with the valves attached) through its diameter. Figs. 7 and 8 are different views of the manner of attaching the inducting valves of one end of the pump to the educting valves of its opposite end. Figs. 9, and 10, are views of the manner of attaching the remaining set of valves. 6, 6, represents the top of the cylinder case, or box, provided with four educting openings, 7, 7, 8, 8, over which the sliding valves 1, 1, l, 1, are made to work. 2, 2, are the inducting valves that work against the ribs 10, 10, as represented in Fig. 4. n 9 isg -a flange for dividing the water passages in;
the chamber of the pump which is part of, the cylinder box. The valves 2, 2, are at-ff vtached to the stem 4 and barrel 5, by means, of the arms 3, .3, as represented in Figs. 7 ,l 8, 9, and 10. In this manner of attaching the inducting valves belonging to one end ofY the pump,with the educting valves at its opposite end, the stem or spindle to which@ they are attached, is divided, as it were,l which enables each set of valves to have a@ separate and independent movement. In,v F ig. 8, the inducting andeducting valvesi are attached to the cylindrical stem, 5, which l works on the stem, 4, as represented in the, Fig. 6, and to which stem the other set ofi valves is attached, as represented in Fig. 10,'.v
thereby giving each set of valves, the power? of opening, independent of the other.
In the place of employing but one educt-f ing valve, there are two at each end of the;
`in a given space.
The manner of attaching the valves together, as before described, does away with the necessity of using a check-valve, and gives the valves a greater freedom, and much quicker action in their operation, and
prevents any flowing back of water after it has once been drawn into the pump.
What I claim as my improvement, and deside to` secure by Letters Patent is- 1. The manner herein described of connecting the inducting valves 2, of one end of a idouble or single acting pump, with the educt- ing valves 1, 1, at its opposite end, on, or. to a separate stem or spindle, so that each set of valves may have an independent movement of the other, in its operation, substantially for the purposes herein set forth in the foregoing specification. 2. I alsoclaim the combination of the tWo educting valves 1, 1, with the inducting val-ve 2,'in order to give each opening lan -A'
