SAFETY CAR LAMP AND STOVE.

SPECIFICATION forming part of Letters Patent N 0. 400,071, dated March 26, 1889. Application filed December 1, 1887. Serial No. 256,614. (No model.)

To CLZZ whom it may concern.-

Be it known that we, OWEN FRANKS and WILLIAM CARROLL, both of Columbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Safety Car Lamps and Stoves, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 is a side sectional elevation of a car provided with our improved lamp and stove. Fig. 2 is a detail side elevation of the releasing device. Fig. 3 is a central vertical section of the stove and releasing mechanism. Fig. a is a perspective view of the shackle connecting the grate and the ashpit bottom. Fig. 5 is a plan view of our improved apparatus. Fig. 6 is an enlarged side elevation of the lamp-operating mechanism. Fig. 7 is a vertical central section of a part of a modi fied form of our improved releasing device, and Fig. 8 shows a modification of the wickoperating device.

Similar letters of reference indicate corresponding parts in all the views.

The object of our invention is to provide simple and eflicient devices for extinguishing fires in the car-stoves, and for extinguishing lamps in case of accident.

Our invention consists in a stove provided with a hinged grate and a hinged ash-pit bot-- tom, and having below the ash-pit a reservoir containin a fire-extinguishing liquid, and in the combination, with the stove, of a catchlever adapted to hold the ash-pit bottom and the grate in the position of use, but arranged to be released by the falling of a weight displaced by a sudden movement or stoppage of the car, as in the ease of a collision or other accident by which the ear is thrown out of its normal position.

It also consists in the combination, with the mechanism, of a device for turning down the wicks of lamps used on the cars, for the purpose of extinguishing the flame.

The stove A is placed in the usual position in the car, and is provided with a combustionchamber, B, having a grate, C, and an ashpit, D, having a bottom, E, hinged to the body of the stove. Below the ash-pit D is supported a reservoir, F, which extends through the floor of the car, and is adapted to hold a fire-extinguishing liquid.

The grate C is connected by a hinge, a, with one side of the stove-body, and is connected with the free end of the ash-pit bottom E bya shackle, G. The shackle G consists of a bar, I), having enlarged heads upon opposite ends, and an arm, 0, hinged to the under surface of the free end of the grate, extending through a hole in the upper head of the bar Z) and provided with a headfll, at its extremity. An arm, 0, similar to the arm 0, is hinged to the ash-pit bottom E, extending through a hole in the lower head of the bar I) and provided with a head, (1. is in place, the arm 0 engages the upper head of the bar I), and the lower head of the said bar engages the head of the arm 0, which supports the grate C; but when the ash-pit bottom E is allowed to fall in the manner presently to be described the bar I) slides down upon the arm 0, and the arm 0 slides in the lower head of the bar I) and allows both the grate and the ash-pit bottom to drop freely.

H is a crank within the reservoir F, its handle extending to the outer side thereof, as shown in dotted lines, Fig. By operating this handle the crank may be turned against the lower face of. the ash-pit bottom E when the same hangs down in the reservoir, in order that said bottom and the grate connected therewith may be raised to their operative positions. The stove is provided with a feeding-door, c, and with an ash-pit door, f, both of which are arranged to be clamped securely in place.

The liquid contained by the reservoir F may consist simply of water or of any of the well-known fireextinguishing solutions. In a tube, I, inserted in the side of the reservoir F, is contained a rod, J, which is provided with a beveled end, g, which projects under the edge of the ash-pit bottom E when closed,

thereby holding the ash-pit bottom and th grate O in the position of use. The rod J passes through a fixed collar, 72, in the tube I, and is provided with a collar, t', between which and'the fixed collar his placed a spiral spring, j, which tends to push the rod J' forward toward the ash-pit. The end of the tube I is partly closed, and the rod J extends \Vhen the ash-pit bottom E through the end of the tube and a short distance beyond it. In the side of the tube I is formed a slot, 71:, through which passes a stud, Z, whose upper end is curved over toward the stove A.

Near the stove A is arranged a tubular column, K, which is enlarged in diameter at its upper end to receive the cap L, the said cap consisting of a ring, 'm, fitted to the top of the column K, and carrying the conical glass portion a of the cap L.

In the tubular column K, near the upper eml thereof, is arranged a crossbar, o', supporting the shallow cup 19 in the center of the column. In the cup 2') is placed a spherical weight, M. A screw-threaded rod, N, extends downwardly from the top of the cap L and receives a follower, 1, which may be moved up or down upon the rod N by the nut '7'. Upon the rod N, near thetop, is placed a nut, s. between which and the collar 1 are clamped the spring-arms n, which extend downward opposite the sperical weight Ill, and are provided attheir ends with concave disks :1. The follower is connecaed by arms ur with the springs 11 at or near their mid-length, and in. the cap L is suspended a scale, (1. To the follower (j is attached an index, I), which moves in front of the scale a. The s jn'ings '11 are adjusted by turning the nut r on the rod N. The adjustment of the springs '21 is such as to allow ot' a certain amount of motion of the sperical weight M without displac' ing it from the cup p, while at the same time the springs a have sutlicient elasticity to allow the spherical weight M to escape from the cup 2) when it receives an extraordinary shock.

To the car-floor is attached a support, to which is pivoted a lever, (I), having a short arm, c, and a long arm, f. The short arm c is engaged by the stud I, and the long arm f extends througl'i a slot, g, in the side of the tubular column K, and provided with a concave plate, 71., for receiving the spherical weight M when the said weight drops. In the side of the tubular column K, near the lower end thereof, is formed an opening, "1", which is closed by a screw-cap, j, and through which the spherical weight M is removed from the tubular column I\' after the operation of the extinguishing mechanism.

Near the outer end of the tul )e I a standard, 1, is secured to the car-floor. In the cars /1", projecting from the standard I, is pivoted a de tent'lever, Q, whose longer arm extends downward below the pivot to a point opposite the outerend of the rod J. In the standard P is also journaled a trigger, R, having a teeth, 1, upon one side and a stud, m, projecting from the opposite side. The teeth I is engaged by the beveled upper edge off the lever Q. A strap,

a, surrounds the standard I and the lever (Q, and is provided with an eye, 0', by which it may be drawn backward when it is desired to disengage the lever from the tooth Z.

A pipe, H, extends from a point over the stud m to the ceiling of the car, thence along the ceiling of the car to a box, T, extending through the center of the car below the lamps U. In the box T are pivoted the levers V, carrying toothed segments 1), which arc capable of engaging pinions g on the wackraising spindles of the lamps. All ot the lower ends of the lovers V are connected by a rod, \V, and to one or more of the said levers V is attached a spring, A, which is adapted to move the entire series of levers when the rod \V is released. A cord, ll, eonnccted \viththc rod \V, passes through 1 he pi pe S, and is provided at its extremity with a ring, 1', which is received on the stud. m, pioiccting from the trigger R.

In Fig. 7 we have shown a modification of the weight-s11pporting device, in which the springs 11 are regulated by a sliding slotted plate, u", in lieu of the follower (1 and arms w, the springs being received in slots in the plate 1.1".

The operatitm of our improved sal'ety car stove and lamp is as follows: The fuel is burned on the grate C in the usual manner, and the ashes and cinders are received uponv the hinged bottom E of the ash-pit l). The levers V are placed in position to engage the pinions (1'. The weight M rests in thecup p. The ash-pit bottom E is supported by the end of the rod J, and the stud m, projecting from the trigger l1, retains the ring the trigger itself being prevented from turning by the engagement of the tooth 7' with the lever (2. The levers V are in this manner held in position against the pressure of the spring or springs A. \Vhen the ear receives a sudden shock, as in a collision, or when it leaves the track or is overturned, the spherical weight M isdisplaced from the cup 1) and falls, striking the plate 71 on the lever (f), causing the lever to tilt, and, by the engagement of the arm c of the said lever with the stud porjecting from the rod J the end of the said rod is withdrawn from beneath the ash-pit bottom E, allowing the ash-pit bottom to drop, and at the same time permitting the grate to drop, thus discharging the contents ot the fire-chamber and the ash-pit into the reservoir 1 where the fire is extinguished by the liquid contained by the reservoir. lliy the same operation the outward movement of the rod J diseugages the lever Q from the trigger It, and thus releases the ring r, allowing the spring A to swing the levers V, and thus revolve the pinions q and spindles (1 turning the lamp-wick down in the lamp, and in this manner extinguishing the flame oil? the lamp.

In Fig. Sis shown a modification. of the lampwick-operating device, in which the knurled heads of the wick-operating spindles are o p crated by a bar provided with notches which allow 01 the turning of the wick-spindles by hand, in the usual way, the rod being arrau ged IlO to contact with the knurled heads and turn them when it is moved lougitudinally, in the manner described in con neetion with the rod to.

Having thus fully described our invention, we claim'as new and desire to secure by Let ters Patent 1. In a car-stove, the combination, with the stove-body A, provided with tight fire and ashpit doors, of the hinged grate C, the hinged ash-pit bottom E, the shackle G, connecting the grate and the ash-pit bottom, the reservoir F, containing a fire-extinguishing liquid, and a fastener for holding the ash-pit bottom in the position of use, substantially as described.
