ALBERT L. WERNERT AND FREDERICK C. DAVISON, OF ATLANTA, GEORGIA.

VALVE.

Specification of Letters Patent.

Application filed January 21, 1911.

Patented Oct. 10, 1911. Serial No. 603,951.

To all whom it-may concern:

Be it known that we, ALBERT L. VVERNERT' and FREDERICK C. DAVISON, citizens of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements in Valves, of which the following is a specification.

This invent-ion relates to certain novel improvements in valves.

In carrying out our invention it is our purpose to provide a valve which is primarily intended for use in connection with gas pipes, and which is provided with means for automatically closing the same when the valve casing becomes heated beyond a certain temperature as in case of fire, and whereby the flow of gas will be stopped.

WVith the above recited object, and others of a similar nature in view, the invention resides in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings,Figure 1 is a vertical longitudinal sectional view taken through the valve casing and the gas pipes connected thereto. Fig. 2 is a side elevation of the valve stem taken upon an enlarged scale.

Referring now to the drawings in detail, the numerals 1 and 2 designate the sections of a gas pipe. Each of these sections has its end threaded whereby the said sections are secured to the opposite threaded ends of a valve casing 3. The said casing 3 comprises a pair of sect-ions designated respectively by the numerals 4 and 5. The section 4 which, for convenience, will hereinafter be referred to as an upper section, is formed with a shoulder 6, from which depends an annular threaded portion 7, and the said threads are adapted to engage with threads 8 formed upon the lower section 5. The depending portion of the upper section has its lower face inclined toward its center to provide a cone-shaped valve seat designated by the numeral 9. The cone-shaped portion 9 terminates in a transversely arranged flange 10 and the said flange is centrally provided with a connecting member 11. This member 11 is formed with an opening 12, the said opening adapted to serve as a passage for a valve stem 13, the said stem carrying a flattened annular removable valve 14. The stem 13 has its upper extremity provided I with a head 15, and adapted to surround the said stem and to exert pressure between the head 15 and the connecting member 11 of the flange 9 is a helical spring 16. The spring tends to force the valve 14 upon its seat so as to close the communication between the sections 3 and 4. The lower face of the connecting member 11 of the flange 10 is formed with a pocket 17 which communicates with the opening 12, and this pocket is adapted to receive a fusible material 18 which is carried by the stem '13. In order to accommodate this material 18, the stem is formed with an annular depression 19, and by this arrangement it will be noted that the valve 14 is normally retained away from its seat, and also that the spring 16 retains the said fusible member within the pocket 12. Should a fire occur in the build-' ing in which the pipe is laid, or should the valve casing be heated beyond a predetermined degree, the fusible material 18 will melt and thus allow the spring 16 to expand to force the valve 14 tightly against its seat 9 and thus cut off the supply of gas. The valve 14 preferably has its central portion provided with a threaded opening and the lower portion of the valve stem 13 is preferably formed with threads which are adapted to engage with the threads of the said opening of the valve. By this arrangement, the valve may be easily and quickly removed from the stem for repairs or for the substitution of a new valve without necessitating the removal of the stem from its locked position upon the connecting member of the flange. It will be further noted that the valve casing being constructed in sections may be readily and quickly separated so that access to the interior of the said casing may be easily obtained and the operating parts within the valve casing may be removed or repaired as desired.

Having thus described the invention, what we claim is:

In a device for the purpose set forth, a casing constructed of a pair of separable members, one of said members being provided with a cone-shaped valve seat which terminates in a transversely arranged flange, a connecting member for the flange arranged centrally thereof and having an opening and having its lower face formed with a pocket communicating with the opening, a valve stem having one of its ends provided with a head and extending through the opening, in the pocket, and a flattened removable 10 t the said valve stem having an annular devalve connected with the valve stem. pression, a fusible member engaging Within In testimony whereof We afiix our signathe depression and adapted to fit Within the tures in presence of two Witnesses.
