Application led August 29, 1902. Serial No. 121.501. (No model.)

tion of the invention, such as will enable' others skilled in the art to which it appertains to make and use the same.

In constructing a sand-box according to my invention I employ two castings for each pair of wheels, each tapering to a nozzle end, to which is attached an india-rubber or other pipe to convey the sand to the rails. These castings are bolted tothe ioor of the tramcar or other vehicle in a position suitable to the gage of the rails. Holes corresponding to the size of the sand-box are cut in the floor, over which hoppers are fixed in such a position as to get a direct fall for the sand. The inside face of the casting is removable and attached to the main casting by bolts or otherwise in order to form a detachable door. The interior of the casting is formed so as to admit an oscillating tumbler with a square hole, and when sand is required this hole is brought to van upright position by suitable mechanism vand when shut off assumes a horizontal position, thus preventing the sand from running to waste. The tumbler works on a spindle, one end of which projects through the main casting and the other through the detachable door above mentioned. To the portion of the spindle on the outside of the casting a pin is attached which works in a boss on the casting formed to allow the tumbler to open fully and close. To the spindle working through the door is attached a crank xed to a bar carrying a similar crank at its other end, this latter crank beingjitted to a crossbar spaced to the. samegage as the boxes. Near the center of the platform, where the car-driver stands, a loose pin passes through the floor and lies in a hole in a crank attached to the center of the cross-bar before mentioned. The cranks fixed to the spindles in the boxes are held in position by strong spiral springs fastened to the framework of the car, so that the sand is shut off or turned on normal position,shut.ing ed the sand.' '.Each sand-box may be made to work independently of the other, if this is required, by disconnecting the crank which controls thatl box which it is not desired to use. A I

In order that my said invention may be better understood, Iwill now proceed to describe the same with reference to the drawings accompanying this specification, in which- Figure 1 shows plan of sand-box; Fig. 2,j

elevation of inside face; Fig. 3, end view; Figs. 4,. 5, and 6, details of tumbler; Figs. 7 and 8, cover detached; Fig. 9, details hereinafter referred to; Fig. 10, plan'showing general arrangement; Fig. 1l, section at B, Fig. 10; Fig. 12, section at C D, Fig. l0. Figs. 10, 11, and 12 are drawn to a smaller scale than the other figures.

The same letters of reference are employed to denote the same parts in all the views. Y

a shows main casting with nozzle end b. This casting is bolted to the floor of the car, as shown at Fig. 11. Holes corresponding tothe size of the sand-box are cut in the floor. Over the casting ct a hopper c is xed.

d shows a detachable door or face attached tothe main casting. v

e` is an oscillatingtumbler mounted onthecasting a, as shown. This tumbler e is formed with a square hole f and may be turned to allow sand to pass, as in the position shown at Fig. 3, or may be turned to block the passage of sand or to any desired intermediate posi` tion. The tumbler e works onY the spindleg, one end of which projects through the main casting and theother through the detachable door d.

h shows pin attached tothe spindle g. Thism is fitted to a bar "n, spaced to the same gage as the boxes'.

o shows a loose pin passing through the floor near the center' of the platform and resting under the recess in one end of the crank p, fixed on the cross-bar a.

q shows spiral spring fastened to l[he framework of the car and by means of a chain to the crank j.

The driver by actuating with his foot the loose pin o turns the tumbler e, so that the sand is turned on or off, as required. The tumbler e may in the same manner be turned partially instead of completely.

fr 7', Fig. 2, show two pieces of rubber or other material placed in slots the full width of the tumbler, so as to prevent leakage from between the tumbler and the main casting.

What I claim, and desire to secure by Letters Patent of the United States of America,

l. In a sanding-box, the combination with a main casting, provided with a hollow chamber therethrough, a hopper above said chamber, a detachable door forming one side of said casting and chamber, an oscillating tumbier mounted in said chamber, journaled to one of the side walls thereof and said detachable door, and provided with an aperture therethrough adapted to Communicate with the delivery end of said hopper, and means for oscillating said tumbler.

2. In a sanding-box, the combination with a main casting, provided with a hollow chamber therethrough, a hopper above said charnber, an oscillating tumbler, having an aperture therethrough and provided with spindles jonrnaled in said casting, means for oscillating said tumbler, a boss on said casting, and a pin on one of said spindles engaging said boss for limiting the oscillation of said tumbler.

3. In a sanding-box, the combination with a main casting, provided with a hollow chamber therethrough, a detachable door, a delivery-nozzle located below said chamber, a hopper above said chamber', an oscillating tum bler, mounted in said chamber, having an apertu re therethrough, adapted to communicate with the delivery end of said hopper and said delivery nozzle, means for oscillating said tumbler, a boss on said casting, a pin carried by said tumbler, adapted to engage said boss for limiting the oscillation of said tumbler, and rubber bushings extending longitudinally of said tumbler for preventing leakage between the tumbler and said casting.

In testimony whereof I aix my signature in presence of two witnesses.

JOHN VILLIAM ENDEAN.
