G. PQBLAKE. Pump and Check Valve.A
No. 198,071. Patented Dec. 11, 1877.

GEORGE F. BLAKE, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN PUMP AND CHECK VALVES.
Specification forming part of Letters Patent No; 198,071, dated December 11, 1877 application filed November 13, 1877.
To all whom it may concern: y
Beit known that I, GEORGE F. BLAKE, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Valves, of which the following is a specification:
This invention relates to valves for pumps or engi-nes; and consists in an indiarubber valve, having its under surface concaved or made dishing from its edge to its center, sub! stantially as hereinafter described, so that when being tted to the face of the valve-seat it will bear evenly thereon, and will not be distorted or curled, also, in combination, a centrally held india-rubber valve, and avalveseat constructed substantially as described, whereby the central portion of the valve, when brought to its seat, moves after the outer portion of the face of the valve, and comes to a seat on the valve-face, all as hereinafter described.
Figure l represents in vertical section a valve provided with my invention; and Fig. 2, a top view of the valve-seat. 4
The valve-seat a., of metal, is provided withv openings b, and has a valve-pin, c, and valvefender d, all of usual construction.
The valve e, instead of beingV made flat on its underside, as usual, is concaved, or made dishing, as shown atf. When the under edge of the outer portion of the valve e rests upon the outer edge g ofthe valve-face the center h of the valve is elevated above the central portion fi of the valve-face. Now, as the fenderdis turned down from the. position shown in Fig. l, to
It is obvious that the same result may be obtained by making the face of the valve-seat concaved, as shown in dotted lines, and the valve a plane surface. This valve is of special advantage when so located that it gravitates away from the seat.
I claiml l. As a new article of manufacture, an india-rubber valve, having 4its under surface concaved or made dishin g from its edge to its center, substantially as described.
2. In combination, a centrally held indiarubbervalve and avalve-seat, constructed substantially as described, whereby the central portion of the valve, when brought to its seat, moves after the outer portion of the face of the valve comes to a lseat on the valve-face, all substantially as described. l
In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses. w
GEO. F. BLAKE.
