UNITED STATES PATENT OFFICE.
LEON B. CARRIGABURU, OF NEW YORK, N. Y.
PUMP.
SPECIFICATION forming part of Letters Patent No. 303,702, dated August 19, 1884.
Application filed November 26, 1883. (No model.)
To all whom it may concern:
Be it known that I, LEoN B. CARRICABURU, of the city and State of New York, have in vented an Improvement in Pumps, of which the following is a specification.
I employ spring-valves of a peculiar construct-i011 that lift from their seats as well as swing to an inclination, so as to allow the water to pass by freely. These valves do not require any hinge, and the seat is'easilykept clean and free from foreign substances. The heads of the valvechest are removable at either sideto give access to the valves.
In the drawings, Figure 1 is a longitudinal section of the pump. Fig. 2 is a cross-section at the line a: w, and Fig. 3 is a perspective view of one of the valves detached.
The cylinder B is provided with heads B and O, and with a piston, b, and rod 0 of any desired construction. The inlet water-way h is formed below the valve-seats 36 and 37, and the ports 6 and 0 pass to the water-cylinder, and the seats 38 and 39 are above these ports and the inlet-valves i and 7c. The exit-valves land m are upon said seats38 and 39, and the top of the valvechest is provided with the water-way D to the delivery-pipe D which pipe may be connected at the top or at the side, or both. When only one deliverypipe is used a stopper, D is to be inserted in the opening that is not niade use of.
It is preferable that the seats and metal partitions of the respective water-ways be all cast in onewith the water-cylinder; but the valve-chambers are open on both sides to allow for facing off the valve-seats and for entering or withdrawing the valves, and movable caps E, Fig. 2, are made use of, one at each side of the valve-chest, and said caps are secured by bolts E that pass through the metal portions of the valve-chest, there being square holes for said bolts, so that they will not revolve, and the nuts are at both ends of the bolts to hold 011 the cap-plates B. By this construction'either cap-plate that is most accessible can be taken off, and should a bolt break it can be driven out and another substituted.
' It is preferable to make all the valves alike, and the peculiarity in the construction is that the valves are made to lift bodily from their seats, and also swing up at an inclination.
Valves have been made with guide-stems and also with springs to press them to place.
Where'the valve lifts bodily and is parallel to V the seat, the water does not escape freely to the side where the greatest quantity passes to the port, and there is unnecessary detention to the water. Where the valve is hinged at one side it does not lift free from theseat, and any solid substance in the water is liable to be thrown upon the seat near the hinge, because there is not suflicient rush of water to prevent the same lodging. By my improvement the valve lifts entirely from the seat and assumes an inclined-position, so that the water is not obstructed in its discharge all around the valve; but the greatest opening is in the direction of the greatest flow of water. To accomplish these objects 1 make use of trunnions 2 2 on thevalve nearly in line with one edge, and I introduce spring valve-carriers S, having helices 3 that surround the trunnions 2, a bow, 4., passing across the back of the valve, and'arms 5 that press against the valveehest above the valve. These arms 5 may eitherterminate as helices or coils, as at (i, surrounding studs that depend from the under surfaces of the valveehest, or else the ends may be bent at right angles and pressed into recesses in the edges of the partition in the valve-ehest, as at 7 7. In either instance the end portions of the spring valve-carriers are heldin place, and the spring of the carrier tends to press the valve to its seat; but when the water acts beneath the valve to open the same, the valve is raised bodily from its seat and assumes an inclined position, because the arms 5 yield to the pressure and the helices form axes for the trunnions to partially revolve in. WVhen the pressure on the valve ceases the springcarrier returns the same to its seat.
I claim as my invention- 1. The pump-valve having trunnions, in comblnation with a spring receiving the trunnions, and acting to close the valve, or to aiplace by the spring and allowed to open and low it to rise bodily from its seat, substanclose, substantially as set forth. [0 tially as specified. Signed by me this 22d day of November, A.
2. In a pump, a valve having tru11nionsex- D. 1888. 5 tending out at the sides, in combination with L. B. OARRIGABUR-U.
a spring having coils around the trunnions, VVitness'es: and arms that press upon the valve and chest, GEO. T. 'IINOKNEY, respectively, whereby the valve is kept in its HAROLD SERRELL.
