SANDING ATTACHMENT FOR AUTOMOBILES.

Application filed August 28, 1922.

To all whom it may concern:

Be it known that we, EDWARD R. TnnciiY and JOHN Nnnsoiv, citizens of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Sanding Attachments for Automobiles, of which the following is a specification.

Our invention relates to sanding attachments for automobiles, and an object is to provide a device by means of which the driver of the car can quickly deposit sand in front of the driving wheels when the car starts to skid on slippery surfaces, thereby checking the skidding action.

The full objects and advantages of our invention will appear in connection with the detailed description, and the novel features of our inventive idea will be pointed out in the claims.

In the accompanying drawings which illustrate the application of our invention in one form in which it may be embodied, Fig.

1 is a side elevation partly broken away showing the device applied to an automobile. Fig. 2 is a view in vertical section on the line 22 of Fig. 1. Fig. 3 is a view in vertical section on the line 33 of Fig.

4. Fig. 4 is a view in vertical section on the line 4-4 of Fig. 8. Fig. 5 is a view in vertical section on the line 5-5 of Fig. 3.

'In the drawings, our device is shown applied to an automobile having the customary floor 10, dash 12, instrument board 14, and running boards 15. A casing 16 which constitutes a sand box is secured to the underside of the floor 10 by brackets 18. This casing has a neck 20 extending through the floor 10 by means of which the casing may be filled with sand, the neck being provided with a closure 22 which when in place is flush with the upper surface of the floor as shown in Fig. 1. Secured by screws 24 to the two running boards 15 on opposite sides of the car are sand receptacles 26 into which extend pipes 28 leading downwardly from the opposite ends of the casing 16. The two receptacles 26 are alike and hence a detailed description of one of them will suffice. As shown in Fig. 3, the rear wall of the receptacle 26 stops short of the bottom thereof so as to provide a discharge slot 30. This rear wall in conjunction with a partition 32 depending from the top of the re Serial no. 584,769.

ceptacle 26 forms a valve chamber, it being noted that the partition 32 stops short of the bottom so as to provide a passageway 34. A rotary valve 36 is mounted in the valve chamber, this valve being cut away on one side to form a flat portion 38. Whcn the valve is in the position shown in Fig. 3, it is closed, and when'rotated in the direction of the arrow so to bring the flat portion downwardly, sand will be permitted to flow out of the discharge slot 30. The two valves are secured by set screws 40 to a rod 42 rotatably mounted in hearings in the side walls of the two receptacles 26. Secured to the rod 42 is a sprocket wheel 44 over which passes a section of sprocket chain 46 the ends of which are secured to crossed cables 48 and 50 which after passing around pairs of guide sheaves 52, 54, and 56 are secured to a hand lever 58 which is supported in suitable manner as by pivoting it to the in strument board 14.

The operation and advantages of our invention will be obviousin connection with the foregoing description. When the automobile starts to skid on slippery surfaces, the driver may almost instantaneously deposit sand in front of the driving wheels by pulling back on the hand lever 58. A pull on this lever causes the two valves 36 to to tate in the direction of the arrow and open the valves so that sand will flow upon the roadway in front of the driving wheels as indicated in Fig. 1 thereby quickly stopping the skidding movement. 'llhereupon the driver may push the hand lever forwardly in order to check the flow of sand. It will be understood that to get the best results, the sand should be dry and of substanti ally uniform size.

We claim:

1. A sanding attachment for automobiles comprising a container for sand, receptacles positioned in front of the driving wheels, pipes leading downwardly from said container to the forward portion ofsaid receptacles, said receptacles each having a chamber formed by the rear wall thereof and a partition therein, said wall and partition stopping short of the bottom of the receptacle to form discharge slots, a rotary cylindrical valve in said chamber said valve being flat on one side, and operating means within reach of the driver whereby said valves may be partially rotated to bring their flat portion either adjacent the bottom of said receptacles or adjacent said partitions. I

2. A sanding attachment for automobiles comprising a container for sand, shutofi' devices connected with said container and positioned in front of the driving wheels, a

rotatable rod to which said shutofi devices are secured, a sprocket wheel secured to said rod, a section of sprocket-chain passing around said sprocket wheel, cables secured to the ends of said sprocket-chain, and operating means within reach of the driver to which said cables are attached.

3. A sanding attachment for automobiles
