ANTISKIDDING DEVICE.

Specification of Letters Patent.

Patented Nov. 24:, 1914.

Application filed September 7, 1912. Serial No. 719,137.

To all whom it may concern Be it known that I, JOHN T. HANNA, a citizen of the United States, residing at Algona, in the county of Kossuth and State of Iowa, have invented certain new and useful Improvements in Antiskidding Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to automobiles and has special reference to an anti-skidding device for vehicles of this character.

The principal object of this invention is to improve and simplify the general. construction of devices of this character.

Another object of the invention is to pro vide an improved form of anti-skidding device which will, by reason of its arrangement, force itself into engagement with the road bed so as to prevent the car slipping sidewise.

With the above and other objects in view as will hereinafter be apparent the invention consists in general of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawing like characters of reference indicate like parts in the several views, wherein:

Figure l is a front elevation of the device showing the colter in section. Fig. 2 is a side elevation of the device.

Referring to the accompanying drawing by numerals 1 indicates the usual axle of an automobile or other vehicle upon which the collar 2 is fixedly mounted. This collar 2- is provided upon its lower side with a depending lug 3 which carries the hinge i. A standard 5 is secured to this hinge 4: whereby the standard 5 may freely swing when desired. A colter 6 is secured to the standard 5 by means of the hinge 7 which is positioned upon the rear side of the standard 5. This colter converges toward its lower side, as illustrated in Fig. 1 for allowing the same to dig into the ground when the same comes into engagement therewith. The forward portion of this colter is rounded, as indicated at 8 for allowing the device to be drawn from engagement with the ground by means of the chain or other lifting member 9.

When this device is used, it will normally extend up under the body of the automobile. By releasing the lifting means 9, however, the weight will cause the colter 6 to fall into engagement with ground. The force of this contact will drive the colter 6 backward until the fiat upper end of the standard 5 engages the lug 3 while the fiat lower end will rest evenly upon the colter 6. In this manner it will be seen that the colter will be held firmly in engagement with the ground while the force upon the forward end of the colter will prevent the same from moving from engagement with the support. As soon as it is desired to remove the colter from the ground by drawing upon the lifting means 9, the standard 5 will swing upon the hinge l while the colter will pivot upon the hinge 7 whereby the colter 6 will move evenly throughout its entire length from engagement with the ground.

From the foregoing description it will be seen that a simple and efficient means has been produced for preventing the skidding of an automobile, this means being so formed as to remain in engagement with the ground, but which may be easily removed when desired.

Having thus described the invention, what is claimed, is

In an anti-skidding device, the combination with a sleeve adapted to be fixedly secured to the axle of an automobile, a de pending short lug integrally formed upon said sleeve, a standard hingedly secured to said lug to the front side of said lug, said standard and said lug being of the same s ze in cross section, said standard provided wlth a squared upper end adapted to abut against and rest evenly upon the lower end of said lug, said standard provided with a squared lower end, a colter hingedly secured to the rear lower end of said standard, said colter comprising an elongated body converging toward its lower edge for digging 1nto the ground, said standard being of the same thickness as the width of the upper portion of said colter, said colter adapted to d1g into the ground for its entire length, said colter bearing evenly upon the lower end of said coltei' forward and out of engagement with the ground.

In testimony whereof I hereunto ailix iny si natui'e in presence of two witnesses.

standard, said standard adapted to limit the rear inoi'einent of said eoltei after said standard extends vertically, the end portions of said standard bearing evenly upon said lug and said coltei' for imparting an endwise thrust upon said lug and oolter whereby said device will be held in its correct position, and means for pulling said Witnesses J. W. SULLIVAN, F. M. SMITH.
