SANDER FOR CARS. I

SPECIFICATION forming part of Letters Patent No. 759,377, dated May 10, 1904.

7 Application filed February 10, 1903- Serial No. 142,818. (No model.)

To on whom it may concern: I

Be it known that 1, BENJAMIN BARNARD J EN- KINs, electrician, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented. certain new and useful Improvements in Sanders for Cars, of which the following is the specification.

My invention relates to improvements in sanders for cars, and particularly trolley-cars; and the object of the invention is to devise a strong, durable, andreadily-operated sander for cars which may be instantaneously applied or cut off and bywhich the sand may be poured in a steady even stream upon the rail until shut ofii, and thereby avoid the skidding of the wheels of the car and the consequent flatteningof such wheels, and subsidiary objects are to prevent the clogging of the sanders by dampness or water, to so construct the sander that it may be readily applied to any car, either underneath the floor-frame or seats, in which the use of springs may be entirely dispensed with and in which the dischargingspout for the sand may be readily removed in case of cloggingandcleansed; and itconsists, essentially, of a sander comprising two cylindrical casings, each having an orifice provided with a suitable adjustable cover, said casings being fastened on a common shaft and each located over a rail, a crank connected to one end of the shaft. a suitable operating-mast extending up through the car in proximity to the motorman and provided with a handle at the upper end and an arm at the lower end, and a rod connecting the latter to the crank on i tail of portion of the car, showing the construction and arrangement of my sander. Fig. 3 is a vertical section through the sander. Fig. 4 is a detail showing the connection of the discharge-spout to the apron.

In the drawings like characters of reference indicate corresponding parts in each figure.

A is the body of the car, B the longitudinal timbers, and O the bottom. 0 represents rectangular openings in the bottom and designed to be closed by suitable covers.

It will be noticed in Fig. 2 the drawing is intermediately broken away.

D D are two cylindrical casings located be:

tween the timbers and suitably secured on the shaft E, which is journaled in bearings F, secured to the timbers. Each casing D is provided with an arc-shaped peripheral cover 03, which has a concentric movement within suit- 1 able guideways d, such guideways being lo: cated atthe outside of the opening d in the casing. The cover (Z is provided with a U-v shaped recess (i and such cover is designed.

to be adjusted so as to cover more or less of the opening d in the casing, as may be re,- quired, depending upon the quantity of sand which may be found desirable to pour through to hold the cover in position.

Gr is a cross-rod, which is supported in suitable arms to the bottom of the car and is designed to form a stop for the lugs 2 and 3 on the periphery ofeach casing, such lugs being made of cast metal and suitably secured to the casing, which is preferably made of sheet metal for the sake of lightness.

. H is a curved-shaped crank secured in the end of the shaft E.

I is a mast, which extends up through the floor of the car, preferably the front platform, and is provided at the top with an operating handle I. able bearings in a vertical position and is provided at the bottom with an arm 1 which is connected by a rod J to the forked end It of the crank H.

K is an apron, which is held by suitable supports in or any other suitable means beneath each casing D, such apron being stationary. The apron K is provided with a central orifice 7c directly-underneath the shaft E. is aflange formed on the edge of the orifice and provided with recesses k diametrically op- The mast I is supported in suitposite each other and extending through the flange k and recesses H, extending portion of the way through the flange.

L is a spout, which is provided with diametrically-projecting lugs Z, which normally rest in the recesses If, but which may be removed therefrom by raising the spout L and turning them opposite the recesses le when the spout may be lowered and withdrawn. It is of course not necessary to withdraw the spout unless the sand when pouring through it should become wet and frozen or otherwise clogged, when of course it is preferable to remove the spout in order to cleanse it.

Having now described the principal parts involved in my invention, I shall briefly describe its operation and utility. By throwing the operating-handle I in the direction indicated by arrow the arm I is thrown in the same direction, and thereby pulls upon the rod J and crank H, thereby partially rotating the casings D until the lug 3' strikes the stop-rod G, at which period the orifice normally at the top of the casing and formed by the opening d and recess in the cover will be directly over the spout L. The centrifugal motion imparted by this operation will stir up the sand, and such sand will pour in an even steady stream down through the spout L onto the rails. It will of course be seen that as long as the handle is thrown in the forward position the stream will continue while the sand lasts, and in order to shut off the flow of sand the operating-handle I may be thrown in the contrary direction to that indicated by arrow, so as to restore the casings D into the normal position, (shown in the drawings,) thereby immediately shutting oif the flow of the sand.

It will be seen on account of the casings D being cylindrical that the weight of the sand will hold the casings in any position to which they may be turned, and therefore in the open or closed position, and consequently there will be no liability of the sand being shut off when understood that should dampness or water accumulate the throw of the cylinder and the consequent agitation of the sand will not allow of the opening being clogged, as every sweep around will necessarily remove any impediment which might have a tendency to adhere around the orifice formed by the opening d and the recesses d on the end of the cover d.

In sanders as heretofore made it has been the common practice to provide springs to restore the parts to their normal position or to help in the operation of the parts; but it will be seen in my construction that this is quite unnecessary and that once the cylinder is set, either to allow of the flow of sand or to shut the sand off, it does not require the attention of the motorman.

What I claim as my invention is- 1. In a sander for cars,the combination with the cylindrical casing having an orifice normally located at the top, and the shaft to which such casing is affixed, and suitable bearings for the shaft, of means for turning the shaft for throwing'the orifice undermost, a stop located in proximity to the periphery of the casing and alug designed to come in contact with the top of such stop so as to hold the orifice in the casing uppermost as and for the purpose specified.

2. In combination in a sander for cars, a shaft, a pair of cylindrical casings thereon, each having an opening for the discharge of sand, a rod Gr extending from side to side of the car and across the peripheries of the cylindrical casings, and stop projections on the said cylindrical casings to strike said rod, substantially as described 3. In a sander for cars,the combination with the cylindrical casing having an orifice therein, of an arc-shaped cover suitable guideways for same, and a thumb-screw for securing the cover in position to vary the size of the orifice, said cover and thumb-screw being arranged outside the cylindrical casing, as and for the purpose specified.

4:. In asander for cars,the combination with the cylindrical casing having an orifice therein, of an arc-shaped cover provided with a U- shaped end designed to be adjusted over the opening, suitable guideways for the cover on the periphery of the casing and means for securing the cover in position as specified.
