RAIL-SANDER.

SPECIFICATION forming part of Letters Patent No. 732,325, dated June 30, 1903.

Application filed March 10, 1903. $erialNo-147,164. (No model.)

To all whom it may concern.-

Be it known that I, JAMES C. THOMPSON, a citizen of the United States, residing at VVilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Rail-Sanders, of which the following is a specification.

In the accompanying drawings, which make partof this specification, Figure I is a bottom plan View of a car, showing the application of one form of my invention Fig. II,a side elevation of the lower part of a car, showing the same form of my invention; Fig. III, a bottom plan view of a car, showing the application of another form of my invention; and

Fig. IV, a side elevation of the, lower part of levers 44, 45, 46, and 47.

a car, showing the latter form of my invention.

My invention relates to sanding mechanism for cars; and its object is to provide such a mechanism which may be operated from either end or platform of the car to apply sand or other material to the rail eitherin front of or in rear of the wheels. In ascending grades it may be necessary to apply sand in front of the wheels to make the wheel take hold of the rails, or in case a car commences to back down a grade to apply sand behind the wheels.

My invention has all the advantages of a sander for applying sand in front of the wheels and in addition thereto of preventing accidents by the application of sand behind backwardly-movin g wheels.

Referring to Figs. I and II, 1 is a car provided with the platforms 2 and 3. At the usual places within the car-that is, at the sidesthereof and under theseats(notshown)- are sand boxes or reservoirs 4, each provided with two spouts arranged to drop sand in front of the end pair of wheels at each end of the car. The spouts are given the numerals 5, 6, 7, 8, 9, 10, 11, and 12, and the sets of wheels adjacent to the spouts are given the numerals 13, 14, 15, and 16, the arrangement of the numerals being such that the pair of spouts 5 and 6 sand wheels 13, the pair 7 and 8 the wheels 14, and the pair 9 and 10 the wheels 15, and the pair 11 and 12 the wheels 16.

The sides of the car are provided with doors 17, through which sand can be put intoboxes 4 without raising the car-seats, as is the usual practice.

The spouts 5 to 12 are provided with sliding gates or valves 18 to 25, respectively, which when moved in a direction away from the spouts permits sand from the boxes 4 to drop down upon the rails, the top of one of which may be considered to be represented by the line 26 on Fig. II.

Beneath the car-body are journaled transversely-of the car the rock- shafts 27, 28, 29, and 30, having rigidly thereon downwardlyextending arms 31, 32, 33, and 34, respectively, and normally horizontal arms 35. These arms and the valves 18 to 25 are pivotally connected by links 36 43, respectively.

On the platforms 2 and 3 are pivoted hand- The upper ends of these levers are within reach of the motorman, and their lower ends, which are below rock-shaft 28, which, through links 38 and 39, withdraws the valves 19 and 21 from beneath the sand in spouts 6 and 8, whereupon the sand falls down the saidspouts and upon both rails. If the car should begin to back,

the motorman pulls the lever toward him,

as shown, which, drawing the link forward, rocks the shaft 29, thereby causing a pull on the links 40 and 41 and the valves 22 and. 24. The valves 22 and 24 are shown withdrawn, permitting sand to drop down the spouts 9 and 1.1 behind the wheels 15 and 16. If the car was moving to the left, the operation would be the same, except that in case sand was to be put in front of the wheels 14 and 15 the valves 23 and 25 would be operated by the lever 47, which corresponds to lever 44, and in case sand was to be dropped back of wheels 13 and 1 4 the valves 18 and 20 would be operated by lever 46, which corresponds to lever 45.

Referring now to Figs. III and IV, 52 rep resents the car, and 53 and 545 the platforms. The sand-boxes are designated as 55, and the doors for filling the same with sand are indicated by 56. The sand-boxes are provided with spouts 57, 58, 59, and 60, which are arranged to drop sand upon the rails. The car has but four wheels, (designated by the numerals 61, 62, 63, and 64.) The spouts 57 to 60 have the valves to 68, respectively, which are connected, respectively, with the levers 69 to 72 by means of the respective links 73 to 76. The levers 69 to 72 are connected, respectively, to the lower ends of the levers 77 to 80 by means of the respective links 81 to 84. The levers 69 to 72 are like levers 44 to 47 of Figs. I and II.

The operation of the second form of my invention is as follows: The car being supposed to go to the right sand will be dropped in front of the wheel 62 by the motorman pulling back the lever 78, which draws forward the link 82, lever 70, link 74L, and valve 66, allowing sand to fall down spout 58. If the car begins to back, sand will be dropped behind the wheel 64 by the operation of the lever 80, which draws forward the link 84, the lever 72, the link 76, and the valve 68, letting sand fall down the spout 60. If the car is going to the left and sand is needed in front of wheel 63, the lever 79 will be operated, which will draw forward the links 83 and 75, the lever 71, and the valve 67, per-,

mitting sand to fall down the spout 59. If the car should back, sand may be dropped back of the wheel 61 by pulling the lever 77, which draws forward the links 73 and 81, the lever 69, and the valve 65, allowing sand to drop down the spout 57.

It will be noted that in Figs. I and II sand is always dropped on both rails at each actuation of the lever by the motorman, while in compartments for containing sand or the like, means for conveying the sand or the like from said compartments to the rails in front of and behind the wheels, valves for controlling the flow of the sand or the like and means on each platform for controlling the said valves.

2. A railway-car, compartments for containing sand or the like, a platform on each end of the car, means on each platform and connections therefrom to the compartments for controlling the flow of the sand or the like either in front of or behind the wheels at will.

3. A railway-car, compartments for containing sand or the like, pipes from the compartments so arranged as to conduct the sand or the like in front of and behind the wheels, valves controlling the flow of the sand or the like from the compartments, rock-shafts on the car, arms on the rock-shafts, platforms at each end of the car, two levers on each platform, connections from the levers and from the valves to the said arms, so arranged that the levers on each platform control the valves for the dropping of the sand or the like in front of or behind the wheels.

4. A railway-car having a platform, compartments for sand or the like, means for conveying the sand or the like so that it may fall in front of and behind one or more of the carwheels, valves for controlling theflow of the sand or the like, mechanical connections from the valves to the platform, and means located on the platform for controlling the said connections so that the sand or the like may be dropped in front of or behind the said wheel or wheels.

5. A railway-car having a platform, oompartments for sand or the like, means for conveying the sand or the like so that it may fall in front of and behind one or more of the carwheels, valves for controlling the flow of the sand or the like, mechanical connections from the valves to the platform, and separate means located on the platform for controlling the said connections so that the sand or the like may be dropped in-front of or behind the said wheel or wheels.
