RAIL-SANDING DEVICE;

Specification of Letters Patent.

Patented Sept. 26, 1905- Application filed December 30. 1904. Serial No. 238,915.

.T (all whom it may concern:

Be it known that I, WVILLIAM THOMAS TATSON, a subject of the King of Great Britain, and a resident of Vancouver, in the Province of British Columbia and Dominion of Canada, have invented a new and Improved Rail-Sanding Device, of which the following is a full, clear, and exact description.

The object of this invention is to provide a simple and strong device for sanding rails and to provide means for insuring a free flow of sand at all times.

The device is intended to be attached to a railway-car and has a discharge-spout leading to the rails on which the car runs, the flow of sand being controlled by the motorman, conductor, or other person, as may be desired.

Reference is to be had to the accompanying drawings, which form part of this specification, in which drawings like characters of reference indicate like parts in the several views, and in which Figure 1 is a sectional view showing the invention in use. Fig. 2 is a plan view with parts broken away. Fig. 3 is a sectional detail on the line 3 3 of Fig. 2. Fig. 4 is a detail perspective of the discharge-spout. Fig. 5 is an end view thereof. Fig. 6 is an end view showing the cleaner in operation. Fig. 7 is a view showing a funnel-like enlargement at the upper end of the spout to facilitate connection with the sand-hopper, and Fig. 8 is a view showing a modification in the construction of the discharge-s out.

10 indicates the san -hopper, which is suitably mounted on the car and has a dischargespout 11 extending from the bottom of the hopper. In said spout is arranged an integral or otherwise-formed ledge 12, coacting with which is a sliding gate-valve 14. Said valve is movable across the discharge-spout 11 and slides in a suitable guide 15, cast integral with the discharge-spout 11 or other wise formed, as may be desired. Said gate has a sharpened edge coacting with the led e 12, the arrangement being such that it would be impossible for a pebble or the like to become lodged between the edge of the gate and the ledge, thus preventing the complete closing of the gate and a consequent loss of sand. At the bottom of the hopper immediately above the gate 14 is arranged a rockshaft 16, provided with a plurality of agitator-fingers 17. Said rock-shaft has one end projected beyond the hopper and provided with an arm 18, the lower end of which is connected to a link 19. Said link extends alongside of the gate 14 and is connected therewith by means of a belt or pin 20. 21 indicates a spring engaged with a hook 22, projecting from the gate and by means of which the gate is held normally closed.

The gate and agitator may be operated by any desired means, but preferably by a link 23, attached to the pin and connected to an arm 24 on a rock-shaft 25. This shaft is mounted in any desired location on the car and has an arm 26, engaged by a pin 27, movably mounted in the floor of the car and adapted to be moved, for example, by the foot of the operator. It will be seen that upon depressing the pin 27 the shaft will be rocked and the link 23 operated to simultaneously withdraw the gate and rock the shaft 16, causing the agitator-arms to break up the sand if it becomes clogged in the hopper and upon the opening of the gate permit sand to pass through the discharge-spout 11 into the sand-spout 29. The sand-spout 29 is attached by brackets 28 to a convenient part of the car directly below the dischargespout 11, and said spout is formed, as shown in Figs. 1, 4, 5, and 6, of an integral sheet of metal bent into tubular form and having its edges 30 rounded, as shown in Figs. 5 and 6, and loosely engaged together. The sheet metal of which the spout is formed is sufficiently elastic to cause said edges 30 to engage tightly together and yet to allow them to be sprung apart by a cleaner or scraper 31. (Shown in Figs. 4 and 6.) Said scraper is introduced between the edges 30 of the spout, the edges springing apart to permit the entry of the tube, which neXt turns crosswise, as shown'in Fig. 6, and moves longitudinally through the spout, completely cleaning out the same. The scraper or cleaner 31 is formed with a round part 31, intended to be entered into the tube, this part conforming with the cross-sectional form of the tube, as shown. In connection with this arrangement it will be observed that when the cleaner is inserted into the tube it loosens any sand which may have accumulated therein, and by moving the cleaner through the tube the last particles of sand are removed.

If desired, the upper end of the sand-spout may be formed frusto-conical, as indicated at 32 in Fig. 7, so as to effectively collect all of the sand falling from the discharge-spout 11 and at the same time to permit a free circulation of air through the spout, so as to allow the sand to dry thoroughly and prevent its clogging. Also the sand-spout may be formed in telescopic sections, as shown in Fig. 8, so that its length may be increased or diminished at will.

Various chan es in the form, proportions, and minor detai s of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the terms of my claims.

Having thus described the preferred form of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A rail-sanding device having a sandspout formed of a sheet of resilient metal bent longitudinally and having its edges loosely engaged.

2. A rail-sanding device having a sandspout formed of a sheet of resilient metal bent longitudinally, and having its edges loosely engaged, said edges being rounded arClld engaging each other at their convex s1 es.

3. A rail-sanding device having a sandspout formed of two sections, each produced from a sheet of resilient metal bent lon itudinally to form a tube, the edges of the sheet being loosely engaged with each other, and said sections being telescoped one Within the other for the purpose specified.

4. A rail-sanding device comprising a hopper having a discharge-spout, a sand-spout receiving the sand from the discharge-spout and adapted to conduct said sand to the rail, a guide projecting laterally from one side of the discharge-spout and surrounding an opening therein, a gate arranged to slide in the guide across the discharge-spout to open and close the same, said spout having an interior ledge projecting into the spout at the side opposite said guide, and the gate being adapted to engage. its edge with said ledge when the gate is in closed position, an agitator arranged in the hopper, and means for simultaneously operating the agitator and ate.

6 5. A rail-sanding device comprising a hopper, a discharge-spout, a sand-spout receiving the sand from the discharge-spout and adapted to conduct the sand to the rail, a guide projecting from one side of the spout and surrounding an opening in the same, a gate movable in the guide to open and close the discharge-spout, an interior ledge in the discharge-spout opposite said opening and adapted to be engaged by the edge of the gate when the gate is in closed position, a rocking agitator mounted in the hopper, means for sliding the gate, and a link connection between the agitator and said means for sliding the gate.

6. A rail-sanding device comprising a hopper having a discharge-spout, said spout having an interior rib at one side and. an opening at the opposite side, a guide projecting from the spout and surrounding said opening therein, a gate carried in the guide and adapted to move in and out of the spout to open and close the same, the inner edge of the gate bein adapted to engage said ledge or rib when the gate is in closed position, a rocking agitator mounted in the hopper, means for moving the gate back and forth, and a link connection between said means and said agitator.

7. A rail-sanding device comprising a hopper having a discharge-spout, a gate adapted to move back and forth through one wall of the discharge-spout, said spout having an interior rib or ledge on its opposite wall, and the ledge being adapted to be engaged by the inner edge of the ate when the gate is in closed position, and means for operating the gate, said inner edge of the gate being sharpened at the point which engages the ledge, for the purpose specified.

8. A rail-sanding device comprising a hopper having a discharge-spout, a gate movable back and forth across the spout to command the same, a rocking agitator arranged in the hopper, means for moving the gate in one direction, a spring serving to move the gate in the other direction, a link in connection with the means for moving the gate, and a crank having connection with the agitator and with the link.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
