UNITED, STATES PATENT QFFICE.
LINUS HUBBARD AND WILLIAM A. HART, OF BUFFALO, NEW YORK.
IMPROVEMENT IN PUMP-VALVES.
Specification forming part of Letters Patent No. 170,737, dated December 7, 1875 application filed November 18, 1875.
To all whom it may concern:
Be it known that We, LINUs HUBBARD and WILLIAM A. HART, both of the city of Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Pump-Valves, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.
The object of this invention is to increase the durability of pump-valves; and it consists of a steel or other hard-metal tubular valveseat piece, having a wrench-section, two screws, and two valve-seats arranged thereonone screw to connect the body of the valve, and one to connect with the valve-cage; or it consists in combining with a pump-valve a reversible double-seated section, as will be more clearly hereinafter shown by reference to the drawing, in which- Figure 1 represents a side elevation of a pump-valve, showing our invention combined therewith; Fig. 2, a vertical longitudinal section through the valve-body and double valveseat. the packing-rings being left off; Fig. 3, a top View, showing one of the valve-seats;
Fig. 4, an enlarged section through the double valveseat piece; and Fig. 5, a section, representin g a modification of our said invention.
nut or wrench section, arranged between the two valve-seats, so that a wrench maybe used to force it in place when required; F F, the screws on each side of the wrench-section. The letters G in Fig. 1 represent the ordinary packing-rings, of leather, which are put on and kept in place, in the usual manner, by means of the part J being screwed tightly against them.
We claim as our invention- 1. A steel or other hard-metal valveseat piece, 0, provided with a wrench-section, E, valve-seats D D, and screws F F, adapted to screw into the body H on one side, and the cage B on the opposite side, substantially as described.
2. A removable reversible double-seated valve-piece, in combination with the parts B and H, as and for the purposes set forth.
