MECHANISM FOR EXTINGUISHING THE LIGHTS IN RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 404,749, dated June 4, 1889.

Application filed July 14:, 1388. Serial No. 279,953. (No model-)- I SON, a citizen of the United States, residing at IVhitman, in the county of Plymouth and State of Massachusetts, have invented certain new'and useful Improvements in Mechanism for Extinguishing the Lights in Railway-Oars; and I do declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of ref erence marked thereon, which form a part of this specification.

Figure 1 is a representation of portions of three railway-cars, showing the devices for operating the flameextinguishers and the manner of connecting the mechanism of one 1 .car with that of the other cars of the train.

Fig. 2 is a transverse and vertical section, on an enlarged scale, of the mechanism applied to each lamp-supporting bracket of the train as set, the parts being in the required position to operate the levers of the flame-extinguishers in case of accident to either of the cars that would be liable to result in the lights setting fire to one or more of them. Fig. 3 is a sectional elevation, in a plane at right angles to that of Fig. 2, of the mechanism shown in the latter figure, the parts of which are in the same position as in said Fig. 2. Fig. 4 is a horizontal section taken on line 1 1 of Fig. 3. Fig. 5 is a side View of the operative mechanism of the flan1e-extinguishers as sprung or set free by means of the weight, which is supported in a cup-shaped bearing formed for it in the frame or supporting-bracket.

The nature of my invention is defined in the claims hereinafterpresented.

In the drawings, A denotes the bracket or supporting-frame for sustaining the lamps B, there being arranged in such frame, and directly over and a short distance from the oilreservoir 0 tl1ereof, a cup-shaped bearing D, for supporting a weight E, attached by means of a chain F, which passes over a guide-wheel G to the lower end of an arm H, pivoted at its upper end to the lower portion of a spring supporting-case I, upheld by standards K, connected to the frame. Within the case I is a head L, which is adapted to slide therein, and is provided with guide-slots a a in its sides, into which the points of screws 1) I), screwed through the case, enter to guide the head in its vertical movements or prevent it from turning horizontally. A spring M bears on the top of the said head L and against the top of the case. Secured to the head L is a rod N, which extends through the bottom of the case and has fastened to its lower end a cross-head 0, from which arms P P project, as represented. Extending from the crosshead is a stud c, which rests on a stud d of the arm II when said cross-head and its arms are set or are in their highest position, as shown in Figs. 2 and 3. Projecting from the arm H is a pin 6, connected to which and to the case I is a spring A lever Q, fulcrumed to the frame at g, rests at its upper end against the pin 6, and at its lower end against the inclined portions hi of the edges of two slides R S arranged to move horizontally in opposite directions in the frame, as shown.

The arms P P are notched at their lower ends, as shown at in Fig. 3, to receive one end of the leverl of the extinguisher applied to the wick-tube of the burners of the lamps.

It is intended that each lamp-bracket in a railway-car shall be provided with the mechanism hereinbefore described, in which case all the slides R will be connected to each other by cords or wires 9%, and all the slides S connected to each other by cords or wires 12. Said cords or wires m and n also connect with levers 0, fulcrumed to each end of the car, the other end of the levers being pivoted to headed slides 19, which are arranged to slide in the ends of the car, as shown. Springs q, arranged on the shank of the slides, hear between the ends of the car and the head of the said slides, as represented.

The operation of the mechanism may be thus described: The mechanism being set as shown in Figs. 2 and 3Which is done by pressing the cross-head upward until the stud d of the arm H is caused by its spring f to swing underthe stud c of the cross-head and sustain said cross-head in its elevated position the levers Z of the flame-extinguishers of the burners are next to be turned on their fulcra till their outer ends bear in the notches 7; in the lower ends of the arms P P. *0 will now suppose the burners of the lamps to be lighted. Should the cars be caused to collide with each other the heads of the slides 19 will strike and press the said slides into the car, turn the levers 0 on their fulcra, and cause them to pull the wires m n, and move the slides R S, and bear their inclines hi against the lower end of the levers Q, and thereby turn said levers on their fulcra g, and' bear their upper ends against the pins 6, and turn the arms H on their pivots, and carry their studs away from the stud c of the cross-heads, and allow the springs M to force the heads L, and consequently the arms P, downward, which will turn the levers Z on their pivots and close the extinguishers over the ends of the burners and put out the lights.

The upper ends of the levers 0 are connected by a line .s','so that in case one car should break away from the others and roll down an embankment, or fall through a bridge, or be overturned, the slides R S will be moved, and consequently the lights put out.

In case one or more cars should be overturned, and from any cause either of the slides R or S should not be moved,the weight E, which will be thrown out of its bearing, will pull the arm TI and move the stud d of the said arm 11 from under the stud c of the cross-head, as shown in Fig. 5, and insure the extinguishment of the lights.

From the above it will be seen that railway-ears provided with my invention would not be liable to be set on fire from the lights in case of accident.

Having described my invention, what I claim is- 1. The mechanism for automatically closing the extinguishers of the lamp-burners of a railway-car, substantially as described, it consisting of the combination of the following elements: the springcase secured to the lamp-supporting frame, its spring, and the sliding head, to which is connected by a rod the cross-head provided with arms having notches to receive the outer end of thelevers of the extinguishers, said cross-head also having a stud c, the levers of the extinguishers, the lever Q, fulcrumed to the frame, the arm ll, pivoted to the case and having the pin 6 and stud (Z, the spring f, for moving the arm H, and the slidestR S, provided with inclines for moving the lever Q, the cords or wires m n, the former connecting the slides R of each lamp-supporting-frame to each other and to a lever 0 at one end of the car, and the latter (the slide S) to each other and to a lever 0 at the other end of the car, the levers 0, slides 11, and springs q, all as set forth.

2. The mechanism for automatically closing the extinguishers of the lamp-burners of a railway-car, substantially as described, it consisting of the combination of the following elements: the spring case, secured to the lamp-supporting frame, its spring, and the sliding head, to which is connected by a rod the cross-head provided with arms having notches to receive the outer ends of the lovers of the extinguishers, the levers of these extinguishers, the arm I-I, pivoted to the case and connected to the spring f for the purpose described, and having the stud (Z to operate with the stud c of the cross-head, the chain F, weight E, guide-wheel G, and the bearing for the weight, all as shown and set forth.

3. The mechanism for automatically closing the extinguishers of the lamp-burners of the cars of a railway-train, substantially as described, it consisting of the combination of the following elements: the spring-case secured to each lampsupporting frame, its spring, and the sliding head to which is connected by a rod the cross-head provided with arms having notches to receive the outer end of the levers of the extinguishers, the lovers of these extinguishers, the arm .ll, pivoted to the case and having the pin e, connected to the spring f, secured to the case, and also the stud (Z to operate with the stud c of the crosshead, the lever Q, pivoted to the frame, the slides R S, provided with inclines for moving said lever Q against the pin 6 of the arm 11, cords or wires on. n, conneetin g the slides, the lever 0, and lines S, connecting the wire of one car with that of the other, all as shown and set forth.

In testimony whereof I affixmy signature in presence of two witnesses.
