SANDER.

SPECIFICATION forming part of Letters Patent No. 660,546, dated October 2 ,1

Application filed July 17,1899. Serial No. 724,159. (No model.)

To all whom it may concern.-

Be it known that I, BENJAMIN BARNARD JENKINS, electrician, a citizen of the Dominion of Canada, residing at Toronto, in the county of York, in the Province of Ontario, Canada, have invented a new and useful Improved Sander, of which the following is a specification.

My invention relates to sanders for automobile vehicles, but more particularly electric or vapor-operated cars; and the object is to devise a form of sander that will be compact in form, easy and convenient ofroperation, but more particularly that will prevent the sand from clogging or loosen it when clogged and cause it to flow freely when required; and it consists, essentially, in providing, preferably in front of one or both forward wheels,-hopper-shaped sand-receptacles having slide-valves operated, either one or both at the same time, from a handle on the front platform, said slides being each provided with a bevel-stop adapted on being opened to engage and release a spring-held lever in such a way as to cause the moving lever and springs which are centrally located in the hopper to loosen up the contained sand, particularly on the sharp recoil of the lever from engagement with the stop on the slidevalve, as more particularly described, and shown in the drawings hereunto attached, in which-' Figure 1 is a perspective sectional view, partially broken away, of a sander and operating mechanism made in accordance with my invention. Fig. 2 is a diagrammatic skeleton plan of forward part of a car, showing relative positions of my sanders and operating mechanism to the wheels and the electric and brake controllers.

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

A is a sand-hopper, having a hole a in the bottom opening into a tube a, adapted to convey sand to the track in front of a driving-wheel. The hole a is opened at will by the slide (1,2, which is normally held within the slot a by the spring a but may be partially withdrawn by the lever B engaging in the hole in the slide o The opposite end of the lever B is connected by the chain b to the crankarm c of the suitably-pivoted cran kshaft 0, which may be operated by the crankhandle 0 when it is desired to let sand through. To prevent the sand from clogging in the hopper, I provide the lever D, centrally pivoted at 01 within the hopper A and preferably having the springs d', connecting its upper end with the ends of the hopper. At each side of the lever D, near the bottom, are pro vided the horizontal springs (1 attached at either end to the ends of the hopper. Crossbars d join the springs d immediately in front of and behind the lever D. To the bottom of the lever D is pivoted the dog 01, free to move rearwardly, but stopped forwardly by the pin d attached to the lever D. To the bottom of the dog d is journaled the roller 01, adapted to be pressed forward by coming in contact with the beveled lug a on the slide a when the slide is being drawn out, thus carrying the lever D and springs d and d with it. When the slide (11 1s moved forward a portion of its full movement, the roller 01 rolls oif the lug o and is thrown violently back to its original position by the springs d and (1 thereby moving and loosening the surrounding sand, causing it to flow. There may of course be other arrangements of springs used or more of them within the principle of my invention, which is to have a snfficient arrangement of springs to stir up the sand throughout the hopper wherever it is liable to cake or clog. There are preferably two such hoppers provided, one for each track. That provided for the opposite side of the car from the operating-crank O is operated at will as follows: Pivoted to the crank-handle c is a grip-lever 0 adapted to be gripped by the hand at one end, which is held normally away from the crank-arm c by the spring 0 To the opposite end is pivoted the slide-rod 0 which slides in suitable guides on the crank-shaft and which on being forced down engage with the slot 0 in the loose collar 0 to which is attached the crank-arm c. The chain b joins the end of the arm 0 with a slide, similar to the slide o in a hopper similarly situated on the opposite side of the car from the hopper A, said chain 17 passing around the wheel I) to give an endwise pull to the slide when the rod 0 is forced into the slot 0 and the crank-handle is turned, when the movement of all parts will be in direction of arrows. I

What I claim as my invention is" 1. The combination in a sander with a sandreceptacle having an orifice at the bottom, normally closed by a movable valve, of a sand-stirrer located within the receptacle and adjusted to be moved by the valve when it moves and springs located within the receptacle and adjusted to be moved by the said sand-stirrer and means for moving the valve, as and for the purpose specified.

2. The combination in a sander,with a sandreceptacle having an orifice at the bottom, normally closed by a slide-valve, of a lug on the slide-valve, lever located and pivoted within the receptacle and adapted to be moved by contact With the lug on the slidevalve, springs located near the bottom of the receptacle on each side of the lever and attached at the ends tothe sides of the receptacle, cross-bars joining the springs close to each side of the lever, and means for moving the slide-valve, as and for the purpose specified.

3. The combination in asan,der,with a sand receptacle, having an orifice at the bottom, normally closed by a slide-valve, of the lug a, the slide=valve a the lever D, the dog (1 the stop-pin d springs connecting the lever D and the sides of the receptacle, and means for moving the slide-valve, as and for the purpose specified.

4. The combination with a sander of the class described, having an orifice at the bottom, of the slide-valve a spring 06*, lever B,

crank-arm c, and handle a, as and for the purpose specified.

5. The combination with two sanders located in proximity to the Wheels of a car,

each having an orifice in the bottom, nor-.

chain b, crank-shaft O suitably journaled,
