LOCKING DEVICE FOR THE GAS COOKE or, s'rovns, imitatie.,` Ann Bananas Applicationnled April 30,1923, Serial No,l 105,758.
Thei present i,nventioii relates to an improved device for locii 'ng y the gasI cocks of, for instance, a kitchen range, so that the cocks may not be opened to permit the flow of gas `until after. the locking device has been moved to unlocking position. In inodern .kitchen gas ranges the usual pilot light located at some distance from the gas cocks, requires one hand of a. person in its operation to shoot the jet of flame over to the desired burner, while the gas cock requires the other hand of a person in its operation to open the flow of gas.
rlhe gas cocks of kitchen ranges, stoves and heaters are sources of constant danger to life and property by reason of being acci` dentally operated so as to open the flow of gas, and also for the reason that children of immature years are prone to turn them on without a realization of the disastrous results that may follow their thoughtless acts.
Safety devices for gas cocks have been patented heretofore, but none of thesel are adapted for use in the now popular form of kitchen ranges which are provided with pilot lights, requiring one hand of the person for operation. My invention is embodied in a construction of gas cocks pro- `vided with a locking device, in which the locking device may be moved into unlocking position, and the gas cock turned by one hand, leaving the other hand free to operate the pilot light.
The invention resides in certain details of construction which will be more fully described in this specification, and the novelty thereof will be pointed out in the appended claims.
In the accompanying drawing:
Figure 1 is a view in elevation of my improved device, looking toward the gas range of which it is a part, and showing in phantom how the same is operated by one hand of a person.
Fig. 2 is a vertical sectional view in the central plane of F 1, showing details of construction, with certain elements in full lines.
Fig. 3 is a. horizontal section on the irregular line 3--3, Fig. 2.
In the drawing, the barrel 10 of the gas cock is formed as a casting having ahollow extension 11 at the right thereof and a lug 12 at the front thereof, formed integrally therewith. Fitted into the barrel is the usual valve 13, provided with a pass 11i, which .parts are in the positions maybe aligned with the .source of supply 15 and the'burner connection 16, by rotating the valve 13 90o through operation ofthe valve handle 17. A i Tlienhoglowv extension 11 receives `a lock-` ing'pm 1 actuated 'by'a spring 1-9 :con-fined" by a cap 20 threaded on the outer end of the extension 11. The valve 13 is provided with a shallow'bore 21 which is entered. by the inner end of the locking pin 18 when the shown, and the arrangement shown and described will prevent rotation of the valve 13 untilafter the end of the spring pressed locking pin 13 has been withdrawn from its engagement with the bore 21. Upon withdrawal of the spring' pressed locking pin 18, the valve mnay be partially rotated to permit the flow or gas such rotation being limited bv the pin 22 set in the valve, as is usual in devices of this class.
To permit the use of a device for the piesent purpose in modern gas ranges provided with pilot lights, the operation of the locking device so as to unlock the valve must be so arranged that such unlocking operation and the partial rotation of the c valve-to open the saine, can be effected bv one hand. To enable this to be brought about, I connect to the projecting rear end of the .spring pressed pin 18, a push bar 23 extend ing parallel with the hollow extension 11 and guided in a perforation in the lug 12 on the barrel 10, the free end of the said push bar being extended to a point within easy reach of the thumb of the hand which is used to turn the valve. The manner of operation is indicated in Fig. 1, by the phantoin view thereon. As a lconvenient means of effecting connection betweeny the spring pressed pin 18 and the push bar 23, I place upon the reduced extended end of the said pin a washer 24, passing the perforated bent end of the push bar 23 over t-he end of the pin, and securing the saine in position bv means of a nut 25 threaded onto the outer end of the pin 18.
Having thus described my invention, what I claim and desire to secure by Letters Pat ent of the United States, is:
1. A safety cock for gas stoves, etc., comprising a barrel and a tubular extension therefrom, a valve arranged for partial rotation in the barrel to control the iow of lgas. a spring-pressed pin arranged in the tubu-I lar extension and engaging a bore in the valveA` such pin acting to prevent rotation or the valve, and a push bar connected at one end to the projecting end of the said pin and serving to Withdraw the engaging enc thereof from the bore in the Valve, and operated by the thumb to permit the Valve to be turned.
Q. A safety cock for gas stoves, ete., comprising a barrel and a tubular extension therefrom, a valve arranged for partial rotation in the barrel to cont-rol the flow of gas, a pin arranged in the tubular eXtension, a spring conined in said tubular eX- tension by a cap thereon for actuating the EDMUND JACH.
