To all who nest may concern:

Be it known that I. Fnnonroir Errernno,

; .a citizen of the United States, residing at Binghamton, in the county of Brooms and State of New York, have invented certain new and useful Improvements in Gas" Cut- 'Ofls fojrlBuildings, of which the following is a specification.

. My invention relates to an improvement 1n gas cut-offs for buildings in which the main flow of gas leading to the basement or interiorof the building may be innnediately stopped or cut oil by manipulating a valve from the exterior of the building in case of fire or other exigency and it has for its object to provide an easily constructed and mounted device simple in operation and with the minimum liability of getting out of order for the purposes aforesaid. a.

of a part of my device shown in connection with airont elevation of another part of my device. Fig. is a vertical side view of a fragmentary part of my device. Fig. .4

is a modified form of a part of my device.

The same reference characters denotelikc parts in each of the several figures of the drawings.-

In carrying out my invention 1 provide a lever box A, having mounted on the front face thereof a pane of glass 2 and on the front face of the inner side of the box I have mounted a lever 3 on the pivot a. On this front face and beneath the lever 3 I have mounted the vertical spring trigger 5 which has contact 6 held '11 contact with lever 3 by the pres sure of the glass 2 upon the spring trlgger 5. Fastene'd to lever 33in any convenient manner I have a small wire cord or cable 7 s which extends downward from box A into 'the basement .or part or thebuilding where the gas pipe entcrs,sa 1d cable having within it a fuse link Z located atanvgconvement point. Mounted on gas 'ilpe I have the; llounted the cut It have the shaft (return cut-oil valve casing c.

off valve casing Q,

with lever 3 at the point pin 8 passing through the casing; C and l have mounted on one end oi? the turn pin 8 the lover' arm .9 to the outer end of which is attached cable 7. On the other end of shaft 8 l have mounted the lever arm 1G onwhich is mounted the weight 11. l, however, may'l elect to have cable 7 connect directly with arm 10 and my device operate without the additional arm 9. Mounted on shaft 8 I shoulder 8. Within tl e cut-off valve casing C I have the partition or wall l3 having in it the valve opening 14:. 7 At a point in the interior of valve casing C, where shaft 8 passes through it, I have'mounted on shaft 8 the arm 15 and loosely mounted on arm 15 l have the disk. 16 held in place by nutl7 and adapted to engage the valve seat 15%. v

in the operation of my device when "a fire occurs or other exigency arises where" it is desired to innnediately cut off the main flow of gas from the building onbasement portion-of the same, the fireman or other person 111 charge immediately breaks glass 2 of the valve box wl'iich is'preierably mounted on the outer part ofthe building and the breakingof glass 52 releases the pres sure upon spring trigger 5, wh ch pressure holds it in contactwith lever 3 and which lever 3 supports cable 7 connecting with arm 9 on shaft 8, and spring trigger 5 being re leased from lever onarm 10 is carried down by gravity from its suspended position heretofore, and it turns shaft 8, which in turn moves downward the interior arm 15, which closes the.

disk 16 down upon seat 18 and thus shuts oil the flow of i what I claim as new and for which I desire Letters Patent is as follows:

1. In a gas cut ofi', the combination with a gas pipe and a valve therein normally tending to close and setting means at a dis.- tance connected to said valve to normally hold it open, said means including a resilient catch and a frangible member upon said catch and holding it under tension and in position to hold the other parts me, the setting means and the valve inopen position, said frangible member when broken releasing said setting means and permitting the valfvelto close.

' 2. In a gascut oilythe combination with 3 the weight 11 mounted Having thus described my invention,*

hearing Mill connected to said valve and adapted to be rocked to open-said valve, a resilient latch ,when placed under tension to hold s'aid rocking :means in its position to hold the valve open and a frangible member bearing on said latch to hold it tensioned but releasing the same and the valve when broken.

3. In-a gas cut-0E, the combination with a valve in a gas pipe normally tending to close, a casing at a distance from said valve, a lever in said casing, a connection between said. lever and said'valve to hold the latter open when the former is turned to a determined position, a spring latch designed to maintain said lever in its determined position, and a frangible side for said casing that holds said spring. latch in engagement with said lever, but when. ruptured releases said latch and permits the valve to close.

'4. In a gas cut-ofi,'the combination with a gravity actuated valve in a gas pipe normally tending to close, a casing at a distance from said valve, a trip controlled means in said casing, a connection between said trip controlled means and said valve to normally hold said valve open, and a frangible side for said casing bearing upon said trip means to maintain it in position to hold the 'alve open, but releasing said means when roken that the valve may close.

5. In a cut-off, the combination with a supply pipe and avalve in said supply pipe, normally tending to close, means at a distance'conneeted to said valve and movable into position to hold said valveopen, a resil lientcatch when placed under tension to ho d said n eans'in its set position for holding the vale open, and a frangible member bearing upon said catch to hold it tensioned, said frangible member when ruptured re-' leasing the catch and permitting the valve to close. I

6. In a gasv cut-off, a box having a glass mounted on the face thereof, a lever within said box, a spring catch or trigger held under tension by pressure thereon ofsaid glass to maintain said lever. in elevated position, a cutoff valve casing. a turn pin passing throughsaid casing, a valve arm projecting from the pin within the casing, a valve on the arm, a valve seat in the easing, a connection from said pin to the lever to hold the valve open, and a weight for closing the valve when the glass is ruptured and the catch released.

7. In a gas cutoff, a box, and a lever mounted within said box, a springcatch or trigger also in the box and adapted when held under tension to hold said lever raised, a glass plate forming the front of the box and bearing on said catch or trigger to hold it under tension in engagement with the lever; a cut-off valve casing, a turn pin or shaft passing through said casing, a valve arm on said shaft, a valve on said arm, a

connection between said shaft and said lever for opening the valve when the lever is raised and holding it open during the elevation of the lever, and a weighted arm on the shaft adapted to close the valve when the glass plate i ruptured and'the catch re leased.

,8. In a gas cut-ofl', a box, and a lever within said box, a spring trigger alsoin said box to support when under tension said lever in raised position, a frangible side for said boxbearing on said trigger and placing it under tension and in position to support said lever, a cut-off valve casing, a

shaft or turn pin passing through said cas ing, an arm on the shaft within the valve casing, a valve on said arm,a weighted arm on one end of said shaft without. the casing tending to close said valve, a connection between said Shaft and the lever, and a fusible link in said connection.

In testimony whereof I have afiixed my signature in the presence of two witnesses.
