AUTOIVIATIC VALVE.

specification of Letters Patent.

applicativa aied August 7, 1914. serial No. 855,577.

To all ful/om t may concern Be it known that I, J ULiUs DINnRs, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Automatic Valves, of which the following is a specification.

My invention relates to an automatic valve or cut off for gaseous fuel burners.

The objects of my invention are to provide a novel valve device of simple and inexpensive construction, which may readily be applied to the pipe line connecting a burner with its supply and which automatically operates to cut oft the How of gas upon detachment of the burner.

My device is particularly useful in connection with gas stoves or other gas burning appliances. Heretofore accidents have sometimes happened with such appliances by reason of the inadvertent detachment of their flexible rubber supply tubes and the consequent unchecked iiow of gas from the end of the tube. By means of my device such accidents may be prevented as the valve is designed to automatically shut off the gas upon detachment of the device from the gas appliance from any cause whatsoever.

I attain the objects specified as well as others not herein enumerated by means of the device illustrated in the accompanying drawings, in which;

Figure l is a vertical section of the device showing the nipple of a detached gas burnopen position by engagement of its plunger with the nipple of an attached gas burning appliance; and Fig. 3 is a perspective view in detail of the valve plunger.

Similar reference characters refer to similar parts throughout the several views.

eferring to the drawings, l indicates a valve chamber provided with a neck 2 having an opening through which gas flows from the chamber. Gas enters the chamber, from the supply pipe 3, through the tubes 4L attached to the sides of the chamber and communicating therewith. The lower end of the chamber l, at the entrance of the neck 2, is interiorly coned and is provided with a suitable washer 5 serving as a seat for the of the disk valve 6.

position shown of gas fromr the 6 is provided projecting through ofthe coupling 9 end, a head l0.

to a gas burning which is preferhown in Fig. 2, in its attached position, the end of the nipple ll presses against the head l0 of the plunger and holds the valve 6, against the action of the Spring 7, away rom its seat so as to permit the free iiow of gas from the chamber to the gas burning appliance. The head 10 of the plunger is preferably constructed as shown in Fig. 3, of two cross bars extending transversely burner.

Should the gas appliance become disconnected or detached, from the coupling, by accident or otherwise, the spring 7 will automatically press the valve against its seat so as to cut oil any yfurther flow of gas iininediately upon the withdrawal of the nipple 1l..

arious changes and modifications may be made in the forni of construction of the device herein illustrated and described witho ut departing from the scope of my invention.

What I claim as my invention and desire to secure by Letters Patent is:

1 An automatic valve comprising a valve chamber having a tubular neck at one end, a valve seat formed therein adjacent the a forked tube spanning said chamber an communicating with openings in the sides of the chamber' above the valve seat, a

spring-pressed valve in inally closing the neck-opening, and a stem on said valve projecting through the neckopening into the bore of the coupling.

n n automatic valve comprising a hollow cylindrical casing open at one end and opening of the having a tubular neck aty the opposite end, a Y screw cap closing the open end of the casing, a Valve seat Jornned in sind casing adj ncent the neck, n Jforked. tube spanning said casing and communicating With openings in theycasing above the Vvalve Sent, n vulve in Said easing, n spring bearing at its ends against the cap and the valve whereby to normally holcl the latter on its seat, a stem 10 on `snidyztlye projecting through the neckopening into the bore of the coupling and carrying at its end a cross-piece.

In testimony whereof, I have hereunto ailixed my signature in the presence of tWo subscribing Witnesses.
