ANTISKIDDING DEVICE FOR'MO'IOR-VEHICLES.

Specification of Letters Patent.

Patented July 20, 1915.

Application filed March 20,1915. Serial No. 15,915.

' To all whom it may concern:

Be it known that I, WILLIAM NORTON, a citizen of the United States, residing at San Francisco, in the county of San Francisco,

and State of California, have invented certain new and useful. Improvements in Antiskidding Devices for Motor-Vehicles, of

which the following is a specification, reference being had to the accompanying drawmg. I

This invention relates to an improved anti-skidding devicefo'r-motor vehicles, and v has for its primary object to provide a very simple and effective device for this purpose, whereby sidewise skidding or sliding movement of the vehicle upon treacherous road surfaces may be prevented.

The invention has for an additional object to provide an anti-skidding device for vehicles embodying a vertically movable part mounted upon the vehicle frame and provided on its lower end with a road engaging shoe, and manually operable means for lowering or raising said part to dispose the shoe in effective engagement with the road surface or in an elevated inoperative position.

It is a further general object of the invention to produce a device of the above character which is strong and durable in its con struction, inexpensive to manufacture and readily applicable to the vehicle without necessitating any changes in its construction, and is highly convenlent and serviceable for the purposes in view.

With the above and other objects in view,

my invention consists in the novel features of construction, combination, and arrangementof parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which,

Figure 1 is a side elevation showing the present invention applied to a motor vehicle frame, the shoe being illustrated in its lowered position in dotted lines; Fig. 2 is a top plan view; Fig. 3 is a section taken on the line 33 of Fig. 1;-and Fig. 4 is a detail perspective view of the shoe.

In the accompanying, drawing, I have shown my invention applied to a motor vehicle frame or chassis 5 which is mounted in any ordinary or approved manner upon the usual front and rear axles 6 and 7, respectively, upon the ends of which the supporting Wheels 8 are arranged. The frame structure 5 includes spaced intermediate transverse bars 9 and the rear tudinal bars 10.

The invention forming the subject matter of the present application, includes a vertically disposed metal'g'uide sleeve or' tube 11 which extends between and above and below the longitudinal frame bars 10. Intermediate of its ends, this sleeve is provided. with oppositely extending lugs or ears 12 to be disposed upon the under sides of the longitudinal bars 10 and secured thereto by suitable bolts .indicated at 13. The lower end of the tube 11 is provided with similar ears 14 to which the lower ends of the inclined parallel longitruss bars 15 are bolted, the other ends of wear awayand leave the centralsteel bar in.

such form as to securely grip the road surface. The shoe is thus, in effect, self-sharpn I Upon one of the transverse bars 9 of the vehicle frame, a hanger bearing or support 21 is secured by the bolts 22. This hanger includes a downwardly extended bifurcated I arm 23 and the spaced upwardly extending ears 24 whichare formed upon the upper end of the hanger and are disposed out of vertical alinement with the arm 23. The lower end of the arm 23 is bifurcated to receive one end of a rod 25 which is provided with a longitudinal slot 26 in which a pin 27, fixed in the bifurcated end of the arm 23, is engaged. The other end of the rod 25 is pivotally connected, as at 28, to the forward end of the shoe 18. In the upwardly projecting ears 24 of the hanger, a lever 29 is fulcrumed adjacent to its lower end. In a bracket member 30 fixed to the rear transpivotally pivotally connected. The lower end of this odis'pivotally connected, asat 3.6, to the I, lower'end'of the, vertically movable rod 16.

' wardly in the. sleeve l1 and lower the shoe 'into'contact with the roadsurface... tudinallyapplliedpressures by means of rod- WhlC I position shown in dotted lines in j 'Fromth'e foregoing description, the 0 er- 5 follows; Assuming that the parts are in the ati'on of my invention will be understoo as icy or slippery road surfaces are en coun "red,- the operator shifts the lever to 'the dotted line' position, and thus actuates the bell crank '31 to force the rod downwardly andthus also slide the rod 16' dow'ii The shoc-is'efl'ectually braced to withstand lon%' is connected to the forward end of the shoe. In this manner, it will be seen that the anti-skidding shoe may be very easily and .quickly lowered into engagement with the road surface or elevated by a reverse movement of the lever to the inoperfa tive position shown in full lines in Fi 1. a It Wlll, course, be obvious that, if desired,

a foot pedal maybe substituted'for the hand lever 29, The mechanism for operating the "shoe might also be actuated by com ressed in ractical use. p dihile I have shown and. described-the the several elements employed, that the device is susceptible of considerable bodied within the spirit invention as claimed. 7

preferred construction and arrangement of it is obvious modification therein, and I, therefore, reserve the privilege of resorting to all such legitimate changes as may" be fairly emand scope of the I Having thus fully described my invention, what I desire to claim and secure by Letters Patent is The combination with a motor vehicle including a frame, of a vertically dis osed guide sleeve fixed in said frame, a ro vertically slidable in said sleeve,- a longitudinallyextending shoe secured to the lowerend of said rod, a hanger bracket fixed upon the machine frame and having a downwardly extending arm,-'a rod pivotally connected to one end of the shoe at its rear end and slidably connected to the'bracket arm at its other end, an operating lever mounted upon said bracket, a bell crank lever fulcrumed in the frame, a rod connected to one arm of said lever and to the lower end of the vertically slidable rod, and a connecting rod between the other arm of said bell crank and'the lower end of 'the operating lever whereby said shoe may be lowered or :ai'sed to its operative or inoperative posi- In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
