v Application filed March 31, 1905. Serial No. 258,132.
To all whom, it may concern: i
Be it knownthat I, ADOLPH W. JnNcz'Ew- SKY, a citizen of the United States, residing at Ch cago, in the county'of Cookand State of Illinois, have invented certain new and useful Improvements in Automatic Safety' Valves for Gas-Supply 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 mvention relates to an automaticallyacting or seli closing safety-valve intended to be apphed to the supply-pipe for illuminat1ng-gas at a point within a house or buildmg and adapted to close the pipe against passage of gas from the main in case a fire occurs within said house or building. i
It has been usual heretofore to provide inthe supply-pipe running from a gasahain into the basement of a building at a point between the meter and the wall through which ,the supply-pipe enters the basement an ordinaryvalve adapted to be closed by a wrench; but 111 case of fire within the building it is I frequently' difl icult, if not impossible,- to
reach saidval ve for the purpose of shutting off the gas, with the result that through the melting or destruction byheat of the pipes or enters the burning building, making it highly dangerous for firemen to enter the same because of habihty of explosion, and frequently resulting inexplosions which endanger life I and destroy property.
"hinged In carrying out my invention Iprovide the. gas-supply pipe within the cellar or basement 3 of the bui din at a point'between the lie s-me- 4- building with a valve having a movable part or closure so constructed that it has tendency -to,-assume a closed position either byl'the ter and the p ace where the pipe enters the gravity of the partjs'or by means of. an actuating-spring,- together with means for holdmg theyalve normally in its open position, embracing a fusible connection, and which -'Will be melted when the valveis subjected to a comparatwelylow degree, of heat, and thus effectetheautomatic closing of the valve.
In said drawing the figure is a view in central lQIlllllldlIlRl section of a-valvehavin a ap orclosure adapted to be closed by gravit As s own in the figureof the accompany- Patented 3111; 3,1906. H
ing into'a building from a gas-main, A a pipe leadingto a gas-meter, and B a valve-casing connecting the ends of the pipes A and AI.
. The valve-casing B is provided at the side of its central chamber nearest the pipe togas flows, with an inclined H 5' ward which the valve-seat b. 1
C indicates'a valve disk or clo to fit against the seatb and attached to 8,113?
arm C, which is mounted on a horizontal pivot D, which extends across the upper part of the valve-chamber above the seat 6.
E indicates a hook or projection extending into theupper part of the valve-chamber at its side opposite the hinge of the closure, 0 an sure adapted eye or loop onithe free end of the lever C, and
F a link, made of readily-fusible metal which en ages'the loop or eye 0 and the hook E and holds the valve-closure in its elevated or openposition. Said hook E is shown as formed on the inner end of a rod E, which extends through the wall of the valve-casing and projects some distance outside of the same. The projecting end of the rod E will be exposed to heat of flames which may surround the valvercasing and will serve to quickly convey oi transmit heat to'the fusible link F. The valve-casing B is shown as provided with screw-cap B, which may be removed. to give access to the parts within the valve-chember.
The valveclosurc or disk C will be held by the fusible link Fin its elevated or open. position, as'shown in the drawing, so that the gas may freely pass through the valve-casing; but
in case ofiire within the building which reaches the nei hborhood of the valve the fusible link will t6 melted and the valve disk or closure will then drop against the seat I), which-latter is inclined in such maniier that the weight of the hinged parts will tendiio. keep the disk againstsaidseat. Moreover, said disk is arranged to close toward the outlet from the casin so that when the disk is e main will tend to hold or press ing the valve-closure open is located entirely within the casing and is adapted to be fused or destroyed by heat transmitted thereto from the exterior of the casing.
A safety-valve embodying my construe tion meybe construct ed injurious forms action ofgravity or other -means to assume it's closed position,-and a link or connection of easily fusible metal or material destructible by heat whichis located within the closed Valve-casing and acts to normally hold the closure in its open position.
