UNITED STATES FATENT OFFICE.
SAFETY-VALVE FOR GAS-PIPES.
Specification of Letters Patent.
Patented July 3, 1906.
Application filed May 10.1905. Serial No. 259-815.
To all whom it may concern:
Be it known that I, ADoLPH W. J ENOZEW- SKY, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Safety-Valves for Gas-Pipes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to an automaticallyacting or self-closing safety-valve intended to be applied to a supply-pipe for illuminating-gas at a point within a house or building and adapted to close the pipe against the passage of gas from the main in case a fire occurs within said house or building.
The invention consists in the matters hereinafter described, and pointed out in the appended claims.
In carrying my invention into practice I provide the gas-supply pipe within the cellar or basement of the building, between the gas meter and the point where the pipe enters the building, with a valve having a movable part or closure, together with means for holding the valve normally in its open position embracing an easily-ruptured supporting member or element and a mass or cartridge of explosive material interposed between the valve-closure and an opposing part of the wall of the valve-casing, which latter is made relatively thin, so that heat to which the exterior of the valve-casing may be subjected may be readily conducted to the explosive, with the result of igniting the same, the explosion resulting from the ignition serving to drive the valve-plug into its seat and close the valve.
As illustrated in the accompanying drawings, Figure 1 is a view in'central longitudinal section of a valve embodying my invention. Fig. 2 is a horizontal section thereof, taken upon line 2 2 of Fig. 1. Fig. 3 is a view in section of the explosive cartridge separated from the other parts.
As shown in the drawings, A indicates a pipe leading from a gas-main, A a pipe leading to a meter or toward the distributingpipes of the building, and B a valvecasing which connects the pipes A and A. Said valve-casing B has a transversely-arranged valve-chamber B, the lower part of which is shaped to constitute a tapered valve-seat.
In said valve-seat are formed lateral ports I) l), which communicate with the pipes Aand A.
C is a valve-plug of conical form, which is movable endwise in the valve-chamber and is adapted to fit within the lower conical part of the valve-chamber B in such manner as to close the ports I) b or to be lifted into the upper part of said valve-chamber.
D is a cap which closes the top of the valvechamber and is preferably connected with the valvecasing by a screw-threaded connection.
I is a screw-cap which closes the lower end of the valve-chamber.
Supporting means for holding the valveplug C in its elevated position consists of a loop a on the upper end of the plug, a loop E,
extending downwardly from the inner surface of the cap D, and a link F, which is engaged with the loops 0 and E. Said loop E is preferably formed of a bent rod or wire, the ends of which are secured in and extend through the cap D and project above or outside of the same. The link F preferably consists of material which is destructible or adapted to be softened by heat. Said loop may be made of lead or other readilyfusible metal, or it may be made of celluloid. If made of celluloid, it will be softened when exposed to heat, so that it will be no longer strong enough to support the plugs, while at ordinary temperatures it is hard and strong.
G is an explosive cartridge interposed between the top of the plug C and cap D. Said cartridge when used in connection with the supporting means of the kind illustrated is made of annular form, so that it may surround the link F, and is provided with an airtight casing or covering g, which may be made of celluloid or like waterproof material. As a convenient construction the top of the plug is made concave and the cap D convex, this shape in the parts affording a chamber for the cartridge having rounded walls and giving a considerable area of contact between the cartridge and the cap D, which latter is made of relatively thin material, so that heat from the exterior of the casing will be readily transmitted to the cartridge.
When the valve-casing is subjected to .a high degree of heat, as will occur when fire occurs in its immediate neighborhood,heat will be transmitted through the thin cap D to the cartridge G, with a result of exploding the same and driving the plug C downwardly into contact with its seat, thereby closing the through and outside of the cap D insures the quick transmission of heat along the arms of said loop to the center part thereof, which is engaged with the link F, thereby making certain the prompt action of the heat on the link,
with the result of melting it, if of fusible metal, or of softening the same to the extent of permitting the easy rupture thereof if of celluloid.
As a further and separate improvement I provide in the valve-chamber B, between the openings 1) 7) and the upper part thereof, which contains the plug C, a closing disk or diaphragm H, which is made of thin celluloid or other easily-destructible or breakable material and the edges of which enter a groove 6, formed in the wall of the valve-chamber. The disk H being of thin and flexible material its margin may be sprung into the groove 6 when the disk is pressed downwardly into the valve-chamber from above. To make a tight joint between the edges of the said disk H and the casing, the groove 6 will be filled around or above the edge of the disk with parafiin or like material. The disk H, inserted in the casing in the valve-chamber, as described, serves to seal the upper part of the chamber containing the plug 0 and the cartridge G against the entrance of gas, thereby preventing corrosion of the plug or injury to the cartridge which would result from the presence of gas and accompanying moisture in the part of the valve-chamber. The part of the valve-chamber below the ports I) b is made deep enough to permit the accumulation therein of solids or liquids, which may enter the valve without interfering with the dropping of the valve-plug to its closed position. The removable cap I affords access to the said lower end of the valve-chamber for removing accumulations therefrom or clean ing the same without disturbing the valveplug and parts associated therewith.
I claim as my invention 1. A safety-valve for gas-pipes comprising a valve-casing, a movable valve-closure in said casing, means for holding the valveclosure in its open position, and an explosive mass or cartridge located within the cas ng in position to act upon the valve-closure in a direction to effect the closing of the valve.
2. A safety-valve for gas-pipes comprising avalve-casing, a movable valve-closure in said casing, means for holding the closure in its open position embracing a member adapted to be weakened or destroyed by heat, and an explosive charge or cartridge located in the casing and adapted to act upon the closure in a direction tothrow the same into its closed position.
3. A safety-valve for gas-pipes comprising a valve-casing, a movable valve-closure within the casing, a connection between the said closure and valve-casing for holding the closure open embracing a connecting member adapted to be weakened or destroyed by heat, and an explosive cartridge of annular form surrounding said connecting member between the valve-closure and a part of the outer wall of the valve-casing.
4. A safety-valve for gas-pipes comprising a valve-casing, a movable valve-closure in said casing, and a breakable diaphragm interposed between the gas-passage through the casing and the part of the casing in which said closure is normally located.
In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses, this 6th day of May, A. D. 1905.
