To all whom/5t may concern:

Be it known that I, OLIVER- H. YOUNG, a citizen of the United States, residing at 239 Steuben street, Brooklyn, New York, have invented newv and useful Improvements in Antiskidding Devices for Vehicles, of which the following is a specification.

This invention relates to an improvement in antiskidding' devices for vehicles and more especially for automobiles.

One of the objects of the invention is to provide a 7 device of this character which may be attached to any type of Wheel without necessitating any alteration in the construction thereof.

Another object is to provide a device of this'character which may quickly and easily be placed in or out of operative position.

Other objects are to provide a device of this character which will be eflicient in operation, simple in construction, not liable to get out of order, and inexpensive to manufacture.

' Other objects will in part be obvious and in part be pointed out hereinafter.

In the accompanying drawings illustrating several embodiments of the invention and in which the same reference characters refer to similar parts throughout the several figures, Figure 1 is a side elevational view of one embodiment of the invention, parts being broken away for the sake of clearness; Fig. 2 is a vertical sectional view of Fig. 1; Fig. 3 is a view similar to Fig. 1 showing a slightly modified form; Fig. 4 is a vertical sectional view showing a modification of the invention; Fig. 5 is a side elevational view of Fig. 4; Fig. 6 is a view similar to Fig. 1 showing another modification; Fig. 7 is a vertical sectional view showing a further modification of the invention.

Referring to the drawin s,.1 indicates the spokes and 2 the felly o a wheel of any suitable construction provided with a tire 3. It will of'course be understood that the invention may be used in connection with any form of wheel and any type of tire without in any way departing fromthe spirit of the invention.

Referring to Figs. 1 and 2 of the drawing,

4 indicates brackets of any suitable construction which are adapted to be secured to the wheel in any suitable manner, and which support an annular member 5 provided with outwardly extending flan es 6, 6. Bars 7 are reciprocatingly carrie by the annular member 5 and have their outer ends secured in any suitable manner to resilient members 8 which have a double looped or S shaped formation. As shown in Fig. l the members 8 are united to one another by substan tially straight portions 8. The resilient members are preferably formed of tempered steel or the like in order to provide the required elasticity and strength. To the lower portion of the looped shaped members 8 are secured ground engaging members 9 which are preferably provided With a concave lower surface.

Rotatably supported in grooves 10 of the flanges 6 is a ring 11 provided with inclined slots'12 adapted to receive pins 13 carried by the supporting rods 7, as clearly illustrated in Figs. 1 and 2. It will be understood that as the ring 11 is turned each of the pins 13 will be caused to travel up or down its cooperating inclined slots 12 thereby raising or lowering the supporting rod 7 associated therewith. As shown in Figs. 1 and 2 the ground engaging members 9 are in their lower or operative position, and they would be raised to occupy their inoperative position by turning the ring 11 in a clockwise direction, which movement of the ring will cause the pins 13 to ride up the inclined slots 12 and into engagement with the upper ends thereof. As shown in these figures the ring 11 is provided, for a portion of its inner circumference, with teeth 14 which are engaged by a toothed wheel 15 mounted upon one end of a shaft 16 rotatably supported upon the wheel in any suitable manner, and having its opposite end 17 squared to be engaged by a wrench or other suitable tool whereby the shaft 16 may be turned. It will thus be understood that when it is desired to raise or lower the ground engaging members 9 it is merely necessary to apply a suitable tool to the squared end 17 of the shaft 16 and to rotate. the shaft in the desired direction.

Referring to Fig. 3 the device is substantially the same as that shown in Fig. l with the exception that the resilient members 8 are not connected to one another. While in these figures a supporting rod 7 is shown adjacent each spoke of the wheel it will of course be understood that the number of supporting .rods and their positions may be varied as desired without in any way departing from the spirit of the invention.

Referrin to Figs. 4 and 5, there is shown an electri'ctilly controlled means for turning the ring 11 which reciprocates the supporting rods 7. 19 indicates an electro-magnet mounted upon the flanges 6 of the annular member 5, and having its armature 20 connected to the ring 11. This magnet is connected by wires 21 and 22 to contact rings 23 and 24 carried by the drum 25 which rotates with the wheel. Bearing upon the rings 23 and 24 are contacts 26 and 27 which are electrically connected with a two way switch 28 and a source of electrical energy such as a battery 29. A second magnet, (not shown) oppositely disposed with respect to the ring 11, is mounted upon the member 5 at another point thereof. It will be understood that by throwing the switch member 40 mounted in a recess 41 and normally held in locking position by means of a spring 42. The locking member 38, which looks the rods in their raised position, is

preferably fixed with respect to the flange 6, while the other locking member 39 is adjustably mounted on the flange, being provided with a slot 43 adapted to receive and proportioned that when the notch 47 receives the locking member 40 in the fixed locking device 38 the rods 7 will be in their uppermost position and the ground engagin members in their inoperative positions. W hen the notch 47 is in engagement with the locking member 40 in the movable locking device 39 the ground engaging members will be in their operative position. It will therefore be understood that the position of the ground engaging members relatively to the wheel may be adjusted to conform with the tire which is carried by the wheel, and it will also be understood that the ground engaging members will be locked against movement in their adjusted positions. If, for example, it isfound that the ground engaging members do not engage the ground with sufficient force to prevent skidding it is merely necessary to move the member 39 to the right (as seen in Fig. 6) a suflicient distance and then to move the ring 45 in an anti-clockwise direction until the notch 47 engages the locking member 40 in the locking device 39. p j

In Fig. 6 the resilient members 8 are shown as being provided with a substantially straight portion 49 adapted tobe secured to the adjacent supporting rod 7, although it will of course be understood that the forms shown in the other figures could be employed therefor if desired.

Referring to Fig. 7 there is shown a mechanical means for turning the ring 11 which means can be controlled by the driver of the vehicle from the drivers seat. This means comprises crown gears 50 and 51 frictionally mounted in grooves in the drum 25 and normally rotating therewith. The gear 50 meshes with a gear wheel 52 mounted on a shaft 53 extending radially of the .wheel, and the gear 51 meshes with an idler '54 WlllCh in turn meshes with a gear wheel 55 also mounted on the shaft 53. Secured to the outer end of shaft 53 is a gear wheel 56 meshing with teeth on a flange 57 carried by the ring 11. Rods 58 and 59 are provided with threaded portions engaging a stationary part of the frame 60, and these rods are adapted to be rotated by suitable levers, not shown, under the control of the driver. These rods are normally maintained out of engagement with the crown gears 50 and 51, but by rotating either of the rods in the proper direction it will be moved into engagement with its corresponding crown gear and the pressure exerted by the rod upon the gear will prevent the latter from rotating with the drum 25. As a consequence of one of the crown gears being held stationary the gear wheel associated therewith will be forced to rotate about its axis as the wheel rotates, thereby causing the ring 11 to turn. It will of course be understood that by reason of the idler gear 54 the shaft 53 may be rotated in opposite directions depending upon which of the crown gears 50 or 51 is held stationary with respect to the drum.

The operation of the device, which should be largely obvious from the above description, is as follows When the roads upon which the vehicle travels are in a condition such that there is no liability of skidding, the ground engaging members are held in their raised or inoperative positions. If,

however, the roads are slippery and there is skidding movement of the vehicle is pre-- vented. Owing to the fact that the ground engaging members are resiliently mounted the device will in no way interfere with the resiliency of the tires and the smoothness with which the vehicle travels will not be affected. By recessing the surface of the ground engaging members their effectiveness is increased as the sharp edges formed by the recess will easily pass through any mud, ice or the like and into engagement with the road surface.
