EUGENE M. MORRIS, OF BALTIMORE, MARYLAND, ASSIGNOR TO HIMSELF AND JOHN BRADY, OF SAME PLACE.
IMPROVEMENT IN WATER AND GAS CUT-OFF OPERATING AND LOCKING MECHANISMS.
Specification forming part of Letters Patent No. 147,958, dated February 24, 1 '74; application filed February 10, 1874.
To all whom it may concern:
Be it known that I, EUGENE M. MORRIS, of Baltimore, State of Maryland, have invented a new and Improved ater and Gas Out-Off Operating and Looking Mechanism; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawpart of this specification, in which t Figure 1 is a side elevation. Fig. 2 is a vertical section of case and mechanism. The invention relates to, and consists in, particular means or mechanism for locking and operating the valve of a gas or water cock, as hereinafter described.
A represents the cock, and B the valve'rod, the latter being connected, by intermediate mechanism, with a device in some room of a building, for the purpose of enabling the oc cupant to shut off or put on his gas or water at pleasure. I attach the upper end of valverod B by a wire, 0, to one arm of a bell-crank lever, 1), whose other arm is connected, by means of rods F, pulleys F, and chains G, with a grooved or rim-concaved drum, E, which has on one side flange a, ratchet e, that is prevented from turning backward by a detent-pawl, L, that is held thereto by a spring,
N N are guides, between which the de 7 M. tent slides, and l, a thumbpiece, which is placed on the outside of the lock-case P, and affixed to the deteut-shank end, that has been passed through said case.
The valve being held firmly to its seat by a spring on the inside of the cock, this spring will cause the chain to unwind from the drum Whenever the thumb-piece is pressed down, and thus made to release the deteut from the ratchet.
Q is a hand-crank of the drum-shaft, by the rotation of which the valve is unclosed to any
