NON-SKID AUTOMOBILE DEVICE.

anessa concemr v at I, Wama:

a citizen of the United States of America, residing at Rioblan'co, in the county of Rio lance and State of Colorado,'have invented certain new-and useful Improvements in To all whom c'tmav 1 Be it known't tin-Skid Automobile Devices, of which the follow ng isa specification, reference being had therein to the accompanying draw- .Another object ofthis invention is the production of a simple and efficient means for raising the anti-skidding devices to'en inoperative position. i

With these and other objects view this invention consists of certain novel combina" tions, constructions, and arrangements ofparts, as Will be hereinafter fully described and claimed.

In the accompanying drawingez-Figure view of the device. Fig. 2

By referring to the drawings it will be seen that 1 designates the frame which is supported by the usual Wheels 2 through the medium of the supporting axles 3 in the usual manner. A central operating shaft 4 is mounted upon the'frame of the machine, and this operating shaft 4 carries a rotating gear 5, which rotating gear is operated by means of a ratchet lever 6. The ratchet 1ever 6 is provided with a spring pressed ratchet 7 which enga es the rotating ratchet wheel or gear 5 for t e purpose or" rotating the shaft 4 as the lever 6 is swung back an forth. A releasing ratchet wheel 8 is mounted upon the central supporting shaft 4 and this releasing ratchet 8 is engaged by means of a pivot dog 9, which dog is ivotally mounted upon the supporting racket 10. This supporting bracket 10 may Specification. of Letters Iatent.

be carried by the base of the machineiil desired manner.

A piyoted treadle 11 is secured upper end of the bracket 10 and is provided the dog 9 in engagement with th ratchet 8. It will be seen that thedog or pawl 9 may be thrown out of engagement with the releasing ratchet 8 by pressin' downwardly upon thelower end 15 foot treadle l1. v

primary sprocket 16 is ,carried b' shaft 4 and an auxiliary sprocket 17 is carried by this shaft, and a primary sprocket chain 18 passes over the sprocket lt'f'and also over a sprocket 19 carried by the rear anti-skidding supportin device 20. An auxiliary sprocket chain 21 passes over the auxiliary sprocket l7 and also over a sprocket Wheel 22, which s rocket wheel is of the the of the machine y means of journal brackets 24-. as is illustrated clearly in Fig. 2: It, of should be understood that: these shafts and 23 as well as the shaft 4 may be supported upon the machine in any de sired manner without spirit of the invention.

Each of the'shafts 20 and 23 are provided with rearwardly extendingsquare project-i ing lugs 25, and upon each of the lugs 25 fits an anti-"skidding "supporting disk arm 26, which arm 26 is provided with a socket 27 a pocketfor receivingthe The lnner end of th plurality' of through which pass the securing bolts 29 Q the arms 26 in, an adjusted pos. sition upon the lugs25. f

Anti-skidding disks 30 are carried between the bifurcated ends 31 o the arms 26 as is clearly illustrated in Figs. 1 and 2 and these disks are preferably sharpened upon their outer edges for the of digging into or cutting into the of the road traveling.

surface over WhlCh' the machme is The rear shaft 20 carries a plurality of forwardly extending finger llsoas to normally hold e releasing also 23. Theshafte on the frame '1" departing from the w e arms 26 is apertures 28 urpose extending finger 12- with the drums 32 to which drums are secured the tension bands '33 by means of the screws 3 Coil springs 35 are connected to the bands 33 as indicated at 36 and the rear ends of these coil springs 35 are connected to the eyes 37 carried by atransversely ext/ending bar '38 mounted upon the frame 1.

By carefully considering the drawings and also by carefully consideringthe above specification, it will be seen that the antiskidding devices and arms 26 may be raised to the position shown in full lines by rotating the gear 5 through the medium of the ratchet lever 6. lhe dog or pawl 9 will prevent the rotation of the shaft 4 in an opposite direction while, the shaft is being wound. After the autizl"dding devices have been raised to the position shown in full lines the same may e released and thrown into immediate engagementwith the road over which the device is traveling by the operator pressing downwardly upon a the foot-trcadle 11 and drawing the pawl or has been produced dog 9 out of engagement with the ratchet 8. The coil springs 35 will thenpull upon the drums 32 and in this manner cause the shaft 20 to rotate and throw the anti-skidding devices into engagement with the road over which the machine is traveling as'is indicated in dotted lines in rigv As the shaft 20 rotates this rotary motion will be imparted to the shaft 4 through the medium of the sprocket chain 18. Rotary movement will also be imparted to the shaft 23 through the auxiliary sprocket chain 2,1,, thereby throwin both'the forward and rearward anti skidding devices simpltaneously into engagement with the road bed. From the foregbing description it will be seen that a very simple and Qll'lClQl'li} device for the purpose of. preventingthe side skidding of an automobile, and at the same time a device has been produced which will be ordinarily held out of engagement with foreign objects while the machine is traveling under ordinary cir-' cums'tances, while the antiskiddingdevices may be thrown into engagement with the road by releasing the dog 9 from engagemea with theratchet 8 as above described;

therewith for allowing carried by tating the rotation of said ratchet, an Z'tl'lXllr' iary ratchet supported adjacent said winding ratchet, means ratchet for normally holding said winding shaft against rotation in one direction and capable of being thrown out of engagement the rotation of said of anti-skidding sprocket wheels said winding shaft, chains for rotating said anti-skidding device supporting shafts as said winding shaft is rotated, anti-skidding arms carried by 'saidfantiskidding device su porting shafts, a drum carriedby one-o said anti-skidding de vice supporting shafts, a flat tension band wound around said drum and secured there to, and a spring engaging said tension band for automatically throwing said anti-skidding devices to an operative position as said auxiliary ratchet is thrown to an inoperative position.

2. A device of the class described comprising a main winding shaft, a plurality of anti-skidding device supporting shafts, anti-skidding devices carried by said antislridding device supporting shafts, manual means for raising said anti-skidding devices,- a winding shaft, a ratchet carried thereby,

winding shaft, a plurality device supporting shafts,

a foot operating dog engaging said ratchet for normally holding the same in a set position, a drum carried by one of said anti-skidding device supporting shafts, and a spring tension belt engaging said drum for automatically throwing said anti-skidding devices to an operative position as said foot operating (log is drawn out of engagement with said ratchet carriel by said winding shaft.
