Description
UNITED STATES PATENT OFFICE.
LINNAEUS E. BAKER, OF FORT WAYNE, INDIANA, ASSIGNOR T0 WAYNE OIL TANK & PUMP COMPANY, OF FORT WAYNE, INDIANA, A CORPORATION OF INDIANA.
Specification of Letters Patent.
Patented Dec. 13, 1921.
Application filed September 18, 1917. Serial No. 191,925.
To all whom it may concern:
Be it known that I, LINNAEUS E. BAKER, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented new and useful Improvements in Check-Valves, of which the following is a specification.
My invention relates, to metallic valves and particularly those of the spring closing check valve type used in pump construction, etc., and is especially useful in mechanism intended to deliver accurately gaged quantities of fluid, such for example as gasolene; its object being to improve and simplify construction, secure certainty and precision of action, and at the same time facilitate inspection, renewal, etc., as a guard against impairment of action from accidental causes.
In the particular embodiment of my invention selected for illustration, my improvement is shown adapted for use as a check valve in the bottom cylinder head of a self-measuring pump and in the same device also applied as a piston valve.
The figure is a vertical axial section through the pump cylinder, bottom cylinder head, and attendant parts.
Referring now to the drawings: C is a pump cylinder, adapted to receive the reciprocating piston A, composed of the crib a fixed to the piston rod a which extends through into the crib to form a valve guide a A follower plate a is threaded into the crib a and has at the bottom an outwardly extending circumferential flange a which securely holds the cup-leather B against the bottom of the crib, while the piston ring D expands the cup-leather in the usual manner. The upper end of the follower plate a has a suitable axial opening to form the valve seat a".
A valve E adapted to seat on the valve seat a has an upwardly extending boss e, bored axially to receive and embrace the valve guide a in a close sliding fit and is provided with a vent e at or near the bottom of the bore. The length of the boss 6 limits the movement of the valve, and the valve guide is of such length as to permit free movement of the valve within this limit,
while the vent discharge tends to regulate and prevent too sudden movements of the valve in relation to its seat.
A slot 6 in the bottom of the valve across the center is adapted to receive a tool for rotation of the valve in grinding the valve to its seat. A springS coiled about the valve boss 6 seats against the under side of the top of the crib a and the upper side of the valve E, and is normally under compression to exert pressure tending to hold the valve to its seat.
Obviously, unscrewing the follower plate a permits the valve E and spring S to be taken out for renewal or repair.
The bottom cylinder head F has a laterally projecting portion f adapted to receive the check valve hereinafter to be described.
The seat f is the counterpart of the seat a The valve and spring are in all respects similar to the other valve and spring before described, and all parts are similarly lettered. The valve guide f is the counterpart of the valve guide 04?, but is fixed to the cap F which is threaded into the bottom cylinder head F in axial alinement with the valve seat 7. This spring S seats against the under side of the cap F and the upper sideof the valve E in the same manner and for the same purpose as the spring of the piston valve.
Obviously, unscrewing the cap F permits the valve E and spring b to be taken out for renewal or repair.
I claim as my invention and desire to se cure by Letters Patent of the United States In an improved check valve, the combination of a casing provided with a valve seat,
a valve adapted to close on said seat, saidi nesses.
LINNAEUS E. BAKER. Witnesses B. F. GEYER, WALTER A. KNIGHT.
