SAFETY GAS-COCK.
SPECIFICATION forming part of Letters Patent N 0. 611,762, dated October 4, 1898. Application filed January 20, 1898. Serial No. 66 7,815. (No model.)
T (0% whom it may concern.-
Be it known that I, REINHARD SCHELBLE, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented a certain new and useful Safety Gas-Cock, of which the following is a specification.
My invention relates to an improvement in the ordinary gas-cock.
The object of this improvement is to prevent the gas-cock from being opened accidentally or unintentionally as, for instance, by being knocked against. I attain these objects by the mechanism illustrated in the accompanying drawings.
Figure 1 is a side View of the gas-cock when shut. Fig. 2 is a top View of the same, also when shut Fig. 3, a vertical section, and Fig. 4. a top view of the same when open.
Similar letters refer to similar parts throu ghout the several views.
The parts G and J K constitute the ordinary gas-cock. In the pipe K is fastened permanently the part E E, which contains two short perpendicular cylindrical tubes open at both ends. In these tubes are two cylindrical rods free to move, held in their highest position by the springsD D and joined across the top by the piece of sheet-brass O, which has its pointed ends bent perpendicularly downward. The chain F is connected to the cylindrical rods by the cross-piece L. Near the top of the turning part Gis attached the small projection B, so that when G has been turned so as to permit the gas to flow B has been turned with it and stands in a position parallel to the pipe K. Now B and O are on such a levelwhen the gas-cock is shut that when G is turned B will almost instantly strike against one of the turned-down ends of 0, thus preventing G from being turned any farther. G may be turned partly before B meets C, but not sufficiently to permit ofthe flow of gas. G is prevented from turning in the other direction by the usual pin, fastened to it directly below J K on the side opposite to B and striking against a projection similar to M. The position described above is indicated by Figs. 1 and 2.
In order to turn Gso that gas may flow, the following manipulation is necessary: The chain F is pulled down, thus overcoming the spring D and drawing Odown below the level of B. G may now be readily turned, B slipping over 0 and taking a position parallel to the pipe K. This position is indicated by Figs. 3 and 4. In order to again shutoff the gas, it is simply necessary to give G a quarter-turn to its original position. 0 will then be released and being forced up by the springs D D take up its primary position.
What I claim as my invention is- In a safety gas-c0ck,'the combination with the gas-pipe J K, having a key-seat therein provided with a downwardly-projecting stop M,an operating-key G secured in said key-seat and provided with a shoulder adapted to contact with the stop M on gas-pipe J K, of the vertical tubes secured in the portion E on pipe K of the gas-cock, cylindrical rods encircled by spiral springs D D joined at their upper ends by the sheet-brass cap 0 engaging the upper ends of the rods D D, and provided with downwardly-bent points engaging the portion E of said gas-cock, the cross-piece Lconnecting the lower ends of said rodsD D, and the operating chain F secured to the cross-piece L, substantially as and for the purpose set forth.
Signed at New York, in the county of New York and State of New York.
REINHARD SCHELBIJE.
