-MECHANISM FOR OPERATING FLUSH VALVES.

UNITED STATES PATENT OFFICE,
LOUIS D. LAWNIN AN D JOHN F. STAAB, 0F EDWARDSVILLE,
ILLINOIS, ASSIGNORS TO N. O. NELSON MANUFACTURING COMPANY, OF EDWARDSVILLE, ILLINOIS, A COIR- PORATION.
MECHANI'SM EUR OPERATING FLUSH-VALVES.
Application filed May 23, 1913.
To all whom t may concern:
Be it known that we, LOUIS D'LAWNIN and JOHN F. STAAB, citizens of the United States of America, residing at Edwardsville, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Mechanism for Operating Flush-Valves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this speci- I'ication.
Our invention relates to a mechanism for operating the valves of flush tanks, and has for its object the production of a simple, eiiicient and inexpensive valve operating mechanism, including an operating lever that receives the connection of the valve rod, and a shaft having means coperable with said valve operating lever whereby the valve operating lever is actuated upon the rotation of said shaft in either direction of rotation.
Figure I is an elevation of a flushing tank, partly broken out to afford a view of the flush valve therein.
Fig. II is an enlarged top or plan view of a wall of the Hush tank and our valve operating mechanism. n
Fig. III is a vertical cross section taken on line III-III, Fig. II.
F IV is an elevation of the valve operating mechanism, the valve lifting lever being partly broken out.
Fio. V is a detail view of the bracket by whicIi our valve operating mechanism is secured'to the flush tank and supported.
In the accompanying drawings:
A designates a flush tank wall and B is a flush valve, which may be of any ordinary construction. The flush valve is carried by a valve rod C, by which it may be lifted upon the operation of our valve operating mechanism.
l designates a bracket that is fitted to `the tank wall A at the location of a non-circular aperture therein, designated a, the bracket having at its face opposing the inner side of said tank wall a non-circular boss 2, the boss and the body of the bracket adjacent thereto being apertured and being provided with a screw thread 3. At the upper end of the bracket l are sockets 4, which receive a rotatable member of the valve lifting lever,
Specification of Letters Patent.
Patented Mar. 13, 1917. Serial No. 769,385.
adapted to turn in said sockets. As will be sockets 4 are parallel with the wall A, and at right vangles Vto the screw threaded aperture extending' through the bracket. The bracket l is held to the wall A lby a connecting screw 5, comprising a head that bears against `the outer face of the wall A, yaround the aperture a, and a shank fittedy to the screw thread 3 in the bracket.
The screw 5 serves as a bearing for a shaft 6, which, by its location in said bearing, is arranged transversely of the wall A and the sockets 4L, and which extends outwardly beyond the outer end of the screw 5 and inwardly beyond the inner end of saidy arm of said double armed lift lever is elevated, and when the shaft is rotated in the other direction, the left hand arm .of the lift lever is elevated.
The shaft 6, with its double armed lift lever 8, serves to operate the valve liftingA lever, which comprises a rockable member 9 mounted in the sockets 4c ofthe bracket l, and an arm l0, extending at an angle from said rockable member, to which the valve rod C is attached.I The rockable member 9 of the valve lifting lever'is mounted in the sockets of the bracket l, and is therefore disposed parallel with said wall and transversely of the axis of the shaft 6 and the double armed lift lever 8 carriedrby said shaft.
1l designates an abutment carried by the rockable member 9 of the valve lifting lever and located above the double armed lift lever 8 carried by the shaft 6. This abutmentextends longitudinally of both the leverV 8 and the rockable member, and it is engaged by both arms of lever 8 so upwardly when either arm ofthe lever 8 is elevated.
It will be readily understood from the foregoing that when the shaft 6 is rotated in either direction through the medium of the handle 7, the rockable member 9 ofthe valve loo that it will be moved lifting lever is rotated, with the result of imparting an upward movement to the arm l0 of said lever, and the lifting of the flushing valve B from its seat.
Special attention is directed to two important features of my valve .operating mechanism, namely, the opposing convex and concave faces of the lift bar 8 and the abutment member 1l. These parts, as a consequence of their formation, work against each other from end to end with a rolling motion. They, therefore, cooperate noiselessly without any jar or shock and with a minimum of wear, so that they will last indefinitely and remain unimpaired.
To limit the degree of rotation of the rockable member of the valve lifting lever, said member is provided with a stop arm l2 which engages the wall of the tank when the valve lifting lever has been operated to a degree suficient to unseat the flushing valve.
We claim In a flush valve operating mechanism, a valve lifting lever comprising a rotatable member and an arm extending at an angle from said rotatable member, said arm being provided with an abutment member having a convex lower face, and a shaft arranged transversely relative to said rota# table member and provided with a lift bar having a convex top face engaging said abutment member to rotate said rotatable Y member.
