FIRE-EX'TINGUISHER FO R RAILWAY-CAR HEATERS AND LIGHTS.
SPECIFICATION forming part of Letters Patent No. 496,682, dated May 2, 1893.
Application filed July 5, 1892- Serial No. 439,040. (No model.)
To all whom itmay concern.-
Be it known that I, JABEZ F. COWDERY, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Fire- Extinguishers for Railway-Oar Heaters and Lights; and I hereby declare the followingto be a full, clear, and exact description of the same. 7
My invention relates to the class of devices for extinguishing the fire in or from stoves, lamps, &c., and extinguishing the lights in railway cars, for the purpose of preventing a confiagration when an accident occurs.
My invention consists in the novel construction, arrangement and combination of the parts of the apparatus or device, which I shall hereinafter fully describe and specifically point out in the claims.
The object of my invention is to provide simple and cfiective means for extinguishing the fire in or from a railway car heater or light, and to extinguish the lights of the gas burners the moment an accident takes place, thus averting the serious confiagration which so often follows collision and other accidents; and also to make these means entirely automatic, and dependent upon the impact of the collision, or upon the movement of the car in being thrown from the track.
Referring to the accompanying drawings for a more full and complete explanation of my invention,Figure 1 is a perspective view of my apparatus. Fig.2 is a view showing the location of parts in the car. vertical section of the adjustable cup P and weight 0.
A is a railway car. Suitably situated in this car is a stove B, which may represent any source of fire, and also suitably placed in any position on, in or under the car is the supply reservoir 0 which is to contain the extinguishing material. In climates where the cold is intense and liquid is used, the reservoir should be placed in the car, but in other places it may be placed on or under the car. This material may be of any suitable character, liquid or gaseous, but preferably the latter.
D is a pipe which connects with the reservoir. Its other end may extend into the stove or to the vicinity thereof. This pipe may be located in any suitable position in the car,
Fig. 3 1s a- In this pipe, atany suitable point, isa cock d which in warm weather, when the stove is not in use, is to be closed, thus v cutting off the reservoir from the stove.
Opening out from and communicating at each end with the pipeD is a branch pipeE on one side, and a similar branch pipe F on the other side. In pipe E is let a cock 6 to the valve stem of which is attached a lever H. One end of this lever carries a weight W which is adjustable thereon and can be fixed in any position to which it is moved by a set screw to. The other end of the lever is formed or provided with a cup h in which is fitted the readily removable weight h. In the other branch pipe F is let a cock f with the valve stem of which is connected the lever I, carrying on one end the adjustable weight W with set screw w, and having its other end formed or provided with a cup 1', in which is fitted the readily removable weight 2'.
Passing into or under the car, in any suitable location, is a rod J, the inner end of which is suitably connected with the removable weight It, as by the short chain W. The outer end of this rod lies in or outside the end of the car, as preferred, and is preferably provided with a cross headj extending the width of the car end. A similar rod K passes into the car from its other end and is connected at its inner end with theremovable weightt" by means of the chain iiand the outer end of this rod has the cross head 10/ These rods J and K are adapted to have alongitudinal movement, and they may be. mounted in any suitable manner. I have here shown them as incased freely in tubular housings or casings L.
In pipe D is let a cock M, having a handle m. With this handle is connected a chain N the other end of which is connected with-a weight 0 set into a cup P supported by a normally horizontal arm Q secured to pipe D. This weight and cup are both peculiarly constructed. The cup is provided with a vertically movable bottom 19 adapted to be raised or lowered by means of a screw p passing through the bottom of the cup. The Weight is a hollow casing containing a heavy material, such for example as shot 0. These are confined by a removable screw cap 0, which provides for the insertion or removal of so much of the weight material as may be desired.
The branch pipes E and F, with their connected parts, can be located in any suitable position on or under the car. I have here shown them as placed under one of the seats R of the car and confined in a box S of sufficient capacity to permit the free operation of the movable parts.
The operation of my extinguisher is as follows:When set for use the cock d in pipe D is opened. The cocks e and fin branch pipes E and F, and the cock M in pipeD are closed, and, therefore, communication between the reservoir and the stove is shut off. The cocks e and fare held normally closed by the superior weights h and '6 respectively. The cock M is closed by being thus set. Now, should a collision or other accident occur by which either or both rods J or K are struck and forced inwardly, the removable weight or weights will be withdrawn from their lever cups h or t and the lever H or I will thereupon be tilted by its weight W or W so as to open either or both cocks e and f, and thereby allow the extinguishing gas, or other material to pass to or near the stove, or to a point at or near the place where the stove stood before the collision, and extinguish its fire, or the fire resulting from the scattering of the fire in the stove, or from lamps or other lights. Should .no collision occur or no accident by which the rods J, K are operated, but such an accident take place as to tilt the car, the weight 0 will be thrown from its cup P and through the connecting chain N will open cock M and allow the extinguishing gas to pass to the stove.
The object of the peculiar construction of weight 0 and cup P, it will now be seen, is to so regulate the weight itself and so adjust its position in'the cup as to render its equilibrium more or less unstable to permit it to be thrown out with more or less ease, as the case may be.
The preceding description relates to the extinguishing of fires in or from the stove or other lights. When arranged for the extinguishing of the lights of'gas burners, in order to prevent conflagration from this cause, the same apparatus is employed. In such case the reservoir 0 stands for any source of illuminating gas, and the pipe D will convey this gas to the burners. The cocks e andf instead of being normally closed will be normally open, and the weighted levers will, upon collision, close them.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A fire extinguisher for railway car heaters and lights, consisting of a supply reservoir remote from the heater and lights, a pipe connected with said reservoir and extending to or near the source of fire, a turnable cock controlling said pipe, a weight connected with the axis of said cock for operating it, and means comprising slidable rods operated by end impact of the cars for tripping the weight, substantially as herein described.
2. A fire extinguisher for railway car heaters and lights, consisting. of a supply reservoir, a pipe connected with said reservoir and extending to or near the source of fire, a turnable cock controlling said pipe, a weighted lever connected with the axis of said cock and slidable rods operated by end impact of the ears for tripping said lever to operate the cock, substantially as herein described.
3. A fire extinguisher for railway car heaters and lights consisting of a supply reservoir remote from the source of fire, a pipe connected with said reservoir and extending to or near the source of fire, a turnable cock controlling said pipe, a weighted lever mounted on the axis of the cock, an impact rod extending to the end of the car, and detachable connections between said rod and the weighted lever whereby the latter is tripped to operate the cock, substantially as herein described.
4. A fire extinguisher for railway car heaters and lights, consisting of a supply reservoir remote from the source of fire,'a pipe connected with said reservoir and extending to or near the source of fire, a turnable cock controlling said pipe, a weighted lever connected with the axis of the cock, aremovable weight carried by said lever to hold it in normal position aholder for the weight, and an impact rod extending to the end of the car and connected with the removable weight, whereby the lever is tripped to operate the cock, substantially as herein described.
5. In a tire extinguisher for railway car heaters and lights, the'combination of a pipe connected with a supply reservoir and extending to or near the source of fire, said pipe having a controlling cook, a lever c011- nected with said cock, and having a weight on one end and a cup on the other, a removable weight fitted in said cup, and an impact rod connected with said removable weight, substantially as herein described.
6. A fire extinguisher for railway car heaters and lights, consisting of a supply reservoir, the pipe D connected with said reservoir and extending to or near the source of fire, the branch pipes let into pipe D on each side and having the cocks, the weighted levers connected with said cocks, said levers having the cups at one end, the removable weights in said cups and the oppositely extending impact rods connected to said removable weights and extending to the ends of the car, substantially as herein described.
