IMPROVEMENT IN ATTACHMENTS T0 GAS-SERVICE PIPETOR AUTOMATICALLY-CUTTINGOFF GAS IN CASE OF "FIRE.
Specification forming .partof Lctters Patent No. ll4,l4 1, dated Apri1'2 5, 1 87 l.
When buildings-which arelighted with gas take fire, it frequently occurs that the lead pipe connecting the meter melts, and from the open pipes large quantities of gas are discharged into the burning building,'f-aggravating the:
conflagration and entailing a heavy loss on the gas-manufacturer; and at such times the service-cock oftencannot be approached on account of the heat, or is rendered useless by corrosion or by being covered with earth.
The object of my invention is to automatically arrest the flow of gaswhen the fire of the burning building melts the meter-connections; and it consistsof a fire-acting gas-valve, composed of an ordinary gas-fitting called a T, i one end of. which is so constructed as to forma valveseat, another gas-fitting called ,a
plug, which is hollow, and a ball-valve secured in the mouth-of the cavity of the plug by means of gas-fitters cement-or other suitable substance.
In order to enable others sk illed' in the art to which my invention appertains tov make and use the same, I will now proceed to de-- scribe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a view of an ordinary gas-fitting T. Fig. 2 is an ordinary gas-fitting plug. Fig. 3is a ball-valve. Fig. 4 is a side view of the entire apparatus attached to the servicepipe. part of. the T being-broken, showing the ball-valve in position over the valve-seat S.
Fig. 5 is a side view of the plug with the ballvalve'secured in the mouth ofcavity.
The gas-fitting T, as represented in Fig. 1, is milled or bored out at S to form a valve seat. Asnow cast, a good valve-seat is formed by the shoulder at S; but to be perfect it should be milled out. The cavity (of the plug P) marked 0 is filled with cement, and the ballvalve B heated and laid on-the cement, which stick together when cooled. The" plug, ballasin Fig. 4, and the apparatus is ready for evident that the ball'B will remain fixed in passage to the gas, until heated to such a degree that the cement melts and releases it, when it falls upon its seat S and arrests the flow of gas, while the melted cement drops down and seals the joint.
It is not necessary that a T should be used under all circumstances-4hr instance, should or other suitable form may be. used instead; also. under some circuinstanceait may be desirable to use the ball-valve at the side where the outlet to the meter is represented, at O,
at the top where the plug and ball-valve are,
neath the seat S.
Having thus fully described my invention,
what I claim as new, and desire to' secure by Letters Patent, is-" p 1.- A valve held separated from its seat by cement or other suitable substance, which're mains solid at ordinary, temperature,-but which will melt when heated above that, thereby releasing the valve'and allowing it to fall down to its seatand shut oil the supply of gas, subforth,
2. A space within the fitting filled with some the valve or ball and flow around it in the valve-seat, thus hermetically sealing the valve, substantially as set forth.
