M. POPKIN. i v GAS VALVE. APPLICATION FILED APB.. 8,1909.

L m r m Huf NN 4 A .f A @o Iig 2 'WmyEssEsf v MORRIS POPKIN, OF MALDEN, MASSACHUSETTS.
eas-VALVE.
'tion may be readily understood, I have disclosed an embodiment thereof in the accompanying drawing, wherein- Figure 1 represents a vertical transverse section upon the broken line Fig. 2, of the gas valve embodyingmy invention in its open position; and Fig. 2 is a similar view upon the broken line Fig. 1 representing the valve as closed.
Gas valves as commonly constructed are provided externally of the fitting with a shoulder against which the valve key is turned in closing. It frequently results, however, that the key is not turned into engagement with the shoulder and that the gas leaks. Moreover such shoulder does not positively hold the valve closed. The valve embodying my invention is of the usual rotary type, but is provided with means for positively locking the valve closed, thus absolutely preventing the escape of gaswhen the burner is not in use, by insuring the closing of the valve and preventing accidental opening thereof.
Referring more particularly to the drawings the valve fitting is represented at 1, it being of any suitable construct-ion and being provided with a gas or fluid passage 2 therein. The fitting is provided with al seat 3, within which is secured in any usual manner a rotary valve 4 provided with the usual port 5 adapted when in the position shown in Fig. 1 to supply the gas to the burner. I provide suitable means to lock or secure the valve 4 positively closed. In order to accomplish this purpose I, in this embodiment of my invention, provide the valve 3 with a substantially axial recess or socket 6 having lateral enlargements 7--7. Within the socket 6 is positioned a sliding member 8 provided with a head 9. Between the Specification of Letters Patent.
Application filed April 8, 1909.
Patented ret. ci, ieri. Serial NO. 488,548.
It is apparent from the foregoing description that a valve constructed in accordance with my invention is positively held closed so that it cannot be accidentally opened after closing. Moreover, the user will not carelessly neglect to turn the key to its closing position when it is known that the key must be turned until it slips into the socket 13.
Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.
1. A gas cock valve or the like comprising a valve seat, a rotary valve seated therein, said casing being prolonged longitudinally of and beyond said valve to form a fixed housing and having a notched end, and said valve being longitudinally socketed, a member longitudinally movable in said socket and positioned within said housg, and having a lateral projection and a terminal key directly to engage said notched portion of the housing, and a coiled spring within said housing and surrounding said member and engaging said projection to force said member into said socket.
2. A gas cock valve or the like comprising a valve seat, a rotary valve seated therein, said seat having a iixed, externally notched portion extending beyond said valve and said valve having an open ended longitudinal socket, a member S slidable in said ino1 socket and having at its outer end a key to engage said notched portion, and a coiled spring surrounding said member S and engaging the same and said valve seat, and serving normally to retract said member 8 Within said socket.
3. A gas cock valve or the like comprising a valve seat, provided With a fixed part having a thumb piece receiving notch, a rotary valve positioned in said seat and provided with a gas port and with a longitudinal socket located Wholly longitudinally beyond said gas port, a member slidably positioned in said socket and provided with an exposed, terminal thumb piece shaped to engage said notch and to be turned to operate the valve, and a spring acting upon said member to retract it Within the socket after being drawn therefrom by said thumb piece and to engage said thumb piece with said notch.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
v MORRIS POPKIN.
