SAND-B0X.

Specification of Letters Patent.

Application filed December 27, 1916. Serial No. 139,171.

To all 'whom t may concern:

Be it known that I, Farmen FLOOD, a citizen of the United States of America, residing at the city of Alba-ny, in the county of Albany and State of New York, have invented certain new and useful Improvements in Sand-Boxes, of which the following is a. specification.

My invention relates to sand boxes, and the object of my invention is to provide a boX for holding sand for distribution upon a railway track, which may be placed in a car, with means for agitating the sand in the box and means for providing for its delivery to the track; together with such other elements and combinations as are hereinafter more particularly set forth.

I accomplish these objects by means of the mechanism illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view partly in section.

Fig. 2 is a view along the lines, 1-1, on Fig. 1.

Fig. 3 is an elevation of the sand conducto-r.

Fig. l is a side elevation, with parts broken away, of a diagrammatic view of my invention applied to a car.

Similar letters refer to similar parts throughout the several views.

In order to keep the sandl for use on a Streetcar track dry, it is advisable to have it stored in the car. Under the best of conditions sand is liable to become moist, caked and difficult to deliver from the sand boX. When the sand boX is on the car it is necessary to have a sand conductor which will lead from the sand boX to a place slightly above the track, and to support this conductor by a bracket, or otherwise, from the truck requires that the conductor shall be eXible. because in turning corners the truck curves through a different arc than the car. I have provided for these and other contingencies in my construction which I now proceed to describe.

, The boX, A, is placed on the Hoor, B, of a car and provided with a discharge opening, C. A sliding plate, D, is provided with an opening, E, which may, by the movement of the sliding plate, be made to register with the discharge opening, C. The sliding plate, D, carries the post, F, to which is pivoted the rod, G, which rod passes through the sand box, A, and has thereon a series of agitator-s, II, which may be in the form shown in Fig. 2, or of any suitable design. Secured to the post, F, is the arm, J, which may be fastened to one end of a link, K, which passes through the floor, B, of the car and is attached to a rod, L, which in turn is connected to one arm of a bell crank lever, M, the bell crank lever secured to a bracket, N, beneath the platform of the car, O, and operated by the pedal, P. The spring, S, is connected with the side of the sand boX at T, and to the post, F. As thus arranged, the spring draws the sliding plate, D, to the position shown in the drawing, closing the discharge opening, C. When the pedal is pressed on, the plate, D, is moved until the opening, E, therein registers with the opening, C, and at the same time the rod, Gr, is moved, whereby the agitators, I-I, thereon move the sand in the box and tend to separate the particles if they have become caked.

Through the floor of the car, I place a pipe, R, provided with a ange, 1, which flange rests upon the floor of the car and upon the surface of which the plate, D, reciprocates. A iexible spring-shaped conductor, U, envelops the pipe, It, below the floor, B, of the car and extends downward to a proper distance above the track, V. The conductor, U, is secured to the ipe, R, in any suitable manner, preferably y a collar, W, provided with projecting portions, w, adapted to be inserted between the adjacent portions of the spring making up the conductor, as shown in Figs. 1 and 3, the collar being secured to the projection, not shown, rozrn the floor of the car by suitable bolts,

4In Fig. 3, I have shown the usual collar, X, which is secured to the truck, Y, and which supports the conductor, W. When a car is going around a curve, the conductor will be bent similar to that shown in Fig. 3, and it is in order to provide and allow for the bending of the conductor, U, and at the same time positively hold the conductor, that I have devised my collar, W.

The collar, W, also may be placed at the lower end of the conductor near the track, as is shown in Figs. 4 and 5.

What I claim as my invention and desire to secure by 'Letters Patent is:

1. In a device for retaining and distributvthrough the sand boX ;v a series of projections on the rod Within the sand boX; and means for moving said sliding plate and said rod simultaneously, substantially as described.

2. In a track sanding device; a pipe eX- tending through the bottom of aV car; a conductor constructed in the form of a spiral spring, the spirals arranged closely together; a collar for supporting the spiral spring; and projections on said collar adapted to be 15 inserted between adjacent spirals of the spring, substantially as described.

In testimony whereof I have aliXed my signature in the presence of tWo Witnesses.

PATRICK FLOOD.
