4 Claims. This invention has as its object to provide an improved equipment for automobiles of the type including generally a container for sand or other abrasive material together with means for supplying air under pressure to the container to effect a discharge of the sand therefrom, and means for delivering the sand to the surface or road in a manner to enable the wheels of the automobile or similar motor vehicle to obtain a positive grip upon a slippery surface and thereby prevent skidding and at the same time insure a positive traction action between the wheels and the road surface. v

Referring to the drawings by reference numerals it will be seen that the chassis of the automobile illustrated in Figure 1 is typical, and that the front wheels 'of the automobile are intaken substantially on dicated by the reference numeral I while the rear wheels are indicated by the reference nu- .merals 2. The chassis or frame bars are indicated by the reference numerals 3 while the reference numeral 4 indicates the propeller shaft and the 5 reference numeral 5 the brake pedal. The transmission shaft connected with the propeller shaft 4 is indicated by the reference numeral 6, and in the present instance, and for a purpose hereinafter made manifest the shaft 6 is provided with 10 a pulley 1. The rod connection between the brake pedal 5 and the brake shaftis indicated by the reference numeral 3. In accordance withthe present invention there is suitably mounted between the chassis bars 3 15 a container 9 adapted to contain sand or other suitable abrasive material Ill. The container .9 is provided with a suitable filling cap II, and at opposite ends thereof with outlets l2 having branches l3, I4. Conduits for the sand are indi- 20 cated by the reference numerals l5, and each conduit is provided with a forwardly extending branch I 6 and a rearwardly exten ng branch l1. Connected with the ends of the rearwardly extending branches l1 are nozzles l8 having flared mouth portions I 8a disposed in proximity to the rear wheels 2. The forwardly extending branches iii are connected with nozzles I 9. that are supported at spaced points by suitable brackets 20v which are in turn secured to the framebars 3. At the ends thereof the nozzles I 9 are disposed laterally and are curved downwardly providing in advance of the wheels I discharge heads or months 20a. As clearly shown in Figure 1 the branches l3 of the outlets l2 are connected with the conduit branches I! while the outlet branches 4 are connected with the conduit branches l6. At the connections between the branches i1 and nozzles l8, and also at the connections between the branches I6 and the nozzles l9 are located valves 2| and each of these valves is shown in Figures 8 and 9 and includes a casing 2111 that connects a. conduit branch with its nozzle, and pivotally mounted within the casing 2 la is a flap valve 22 which in closed position engages a stop 23. Externally of the casing 2| the valve 22 is provided with a crank 24 to which is connected one end of a spring 25 that is suitably anchored at its opposite end to the casing as suggested. in Figure 8. Under action of spring 25 the valve 22 -50. is normally retained in closed position, that is the full line .position shown in Figure 9. To effeet a positive discharge of the sand from the container 9 there is provided a suitably mounted air tank 26 that has outlets 2! connected with bers 33 that engage r the conduits l5,

. ing movement and to and at the connections between the outlets 21 and the conduits" are control valves 23. For normally retaining the control valves 23 in closed position the cranks 23:: thereof' are connected with one end of springs 23 anchored to one side of the tank 23 as clearly shown in Figures 1 and 2.

The tank 23 is supplied with air through a conduit connection 33 between the tank 23 and an air compressor 3|.

The compressor transverse support the compressor 3| is 3| is mounted to slide on a 32, and at the base thereof provided with channel memthe side edges of the member 32 for guiding the compressor 3| in its slidretain the compressor in proper engagement with the support 32.

The shaft of the compressor 3| is provided with a pulley 34 and the compressor is adapted to be driven from the motor shaft 3'through the medium of a belt 35 trained over the pulleys 1 and 34 as shown in Figure 1. 1

Any suitable dash control means 33 may be employed for shifting the compressor 3| along its support 32, and in the present instance such control means 33 is connected with the compressor 3| through the medium of a cable 31, an intermediate portion of which is trained over a suitably'mounted pulley 33. The compressor 3| is normally retained at one end of its support 32 through the medium of coil springs 33 anchored at one end to brackets 43 and connected at an opposite end with the members 33 as suggested in Figure 12. Obviously when the compressor 3| is in the position shown in Figures 1 and 12 drive may be transmitted from the shaft 3 through the belt and pulley means to the com pressor for operating the latter. When it is desired to interrupt this drive the operator properly manipulates the control 33 in order to exert a pull on the cable 31 against the action of springs 33 to cause the compressor 3| to move inwardly toward the transverse center of its support 32. This inward movement of the compressor will cause slack to develop in the belt 33 sufllclent to interrupt the drive between the shaft 3 and the compressor.

The air tank 23 is provided with a suitable relief valve clearly shown in Figure 10 as indicated by the reference numeral 4|. The equipment also includes as a part thereof a suitable air gauge 42 that may be conveniently mounted on the instrument board, and'this air gauge is connected with the tank 23 through the medium of a conduit 43. r

For opening the valve 23 to permit a discharge I .of sand through the nozzles I3 and I3, incidental to an application of the brake the following mechanism is provided. A transversely mounted rock shaft 44 is provided with arms 45 that are connected through the medium of links 43 with the cranks of the valves 23. The shaft 44 is also provided with a crank arm 41 and pivotally connected to the crank arm 41 is one end of a control rod 43. At its free end the rod 43 is formed as at 431: and adapted to engage a block 43 secured at any desired position on the aforementioned pedal rod 8. The end 43:: of the rod 43 is normally and releasably retained in the path of movement of the block 43 through the medium of aspring member 53 having a free end shaped as at 5| to straddle the rod 43. The spring memspring 50 will return to its and I4. This suction will be suflicient to draw the sand from the container '3 in a manner to effect a positive and emcient discharge of the sand through the nozzles l3 and I3 on to the road surface and in the region of the wheels I and 2 of the automobile and in advance of the wheel to thereby prevent skidding and insure a tractive, action between the wheels and the surface of the road.

In this connection it will be apparent that the force of the air and sand against the valves 22 will be sufllcient to cause the valves to swing upwardly to the dotted line position shown in Figure 9 so as not to interfere with the passage of the sand through the conduits and discharge nozzles.

' When it is desired to operate the brake pedal 5 without disturbing the position of the valves 28 the operator by pulling up on the hand rod 34 that is connected at 43 will draw the rod 43 upwardly to the dotted line position shown in Figure 4 and thereby place the end 43:; of the rod out of the path of movement of the block 43. The spring 33 will of course yield to the pull exerted on the rod 54 to permit the rod 43 to move from the full line to the dotted line position shown in Figure 4. Upon release of the rod 54 the rod 43 under action of normal or full line position shown in Figure 4.

Having thus described my invention," what I claim as new is:

l. A sanding unit attachment for disposition on a motor vehicle, said attachment comprising a sand container, conduit pipes leading therefrom, valves operable to control the discharge through said conduits, and means for operating the valves from the brake pedal of the vehicle, an air tank in communication with the sand container, an,
