ANTISKIDDING DEVICE.

Specification of Letters Patent.

Patented May 16, 1916.

Application led August 21. 1915. Serial No. 47,541'.

provements in the construction of the antiskiddingdevice for which Letters Patent of the United ntates numbered 1,117,040 were issued t6 inc on the 20th day of July, 1915; and has forit's objects: First, to provide an improved antiskiddingdevice so mounted upon the frame of a motor vehicle or the like that shocks and vibrations received by the device will be prevented from reaching the frame 'or chassis of the vehicle. Second,

to provide an improved device of the character described having-resilient shock absorbing means interposed between the contact shoe and the operating means therefor. Third, to provide an -improved device that shall be simple, effective, cheap and durable in construction and in operation.` Fourth, to provide an improved device of the character described that shall be inconspicuous when in an inoperati c p'isition so as not to mar or detractq from tle appearance of the Jar or vehicle. 1 accomplish these several features by means of the device disclosed in the .lrawings forming` a part of the present specifications wherein like characters of reference are used to designate similar parts throughout the said specifications and drawings and in whichlfg'ure 1 a broken side elevation of a rar lor vchiU-e with the `body and nigh rear v. heel removed in order'to disclose the manner in which the improved device is attached thereto, the dotted lines indicating the inoperative, and 'the full lines indicating the operative positions, respectively. Fig. 2

Vis a transverse sectional view taken on line X-X of Fig.' 1 of the drawings in the direction indicated.

referring to the drawings the numeral 1 is used to design-.ite a verticall v disposed tubular mci'uber pivotall)7 mounted, by means of trunnious 2, between longitudinal channels 3 offa frame or chassis 4. The member 1 is also provided with longitudinal slots 5 and lateral lugs (i on the. lowerend thereof to which lugs G are secured lateral inclined braces T, said braces 7 being secured at their upper endsY to the trunnions 2 but on the opposite sides of the channels 3, thereby providing asuitable support against lateral movement.

lV hat I term a sleeve S, to differentiate from the tubular member 1, is slidahly mounted within said tubular member 1 and is provided with lateral lugs 9 Vwhich pro- `iect through and beyond the slots 5 of .said member 1. r1`he upper end of the sleeve 8 is closed as at 11 while the lower end thereof is provided with an annular flange 12 adapted to engage and raise a plunger or piston 14 secured to a stem 16 of alongitudinally disposed shoe 17, having longitudinal grooves 18 in the bottom thereof. A suitable spring 19 is interposed between the top of the plunger or piston 14: and the closed.v

top 11 of the sleeve 8, the purposeof which will hereinafter more fully appear. A bell crank lever 21 is pivotally mounted upon a b 'acket 22 rigidly secured to the chassis or frame 1 and is provided with a bifurcated arm 23 which is operatively connected to the lugs 9 of the sleeve 8 by means of connec-ting links 24, while the other arm 26 of the bell crank lever 21 is operatively connected, by means of a suitaole connecting rod 27, to the lower end of an operating lever 28 pivotally mounted upon a sector 29 secured to the chassis or frame t. H is provided with the usual detent 31 and releasing latch The forward end of the shoe 17 is connected to the forward part of a machine ,by means of a suitable rod 33 which is secured to a somewhat flexible metallic bracket 3G.

The operation is as follows: lVhen inoperative the device will be positioned as discloscdin dotted lines in Fig. 1 of the drawings. lVhen the vehicle starts to skid or move sidewisc thc rear wheels 34 will not follow the front wheels To prevent a side movement of the rear wheels and rear portion of the car or vehicle the lever 28 -is moved to the position indicated in full lines in Fig. 1 of the drawings which action will cause the bifurcated arm 23 of the bell crank lever 21 to move the sleeve 8 and shoe 17 slidably mounted therein downward and the latter into contact with a roadway. the shoe has formed such Contact an additional pressure is brought to bear on the lever 28 until the spring 19 is compressed between the top of the piston 11 and the closed top 11 of the sleeve 8. The detent 31 'ill normally prevent a release or return of The lever the lever 28 and consequently the shoe 17 will be held in contact with the roadway thereby causing the grooves 18 to engage said roadway and thereby prevent a lateral or skidding movement of the vehicle. lVhile in this position the pressure will be .upward through the stem 16 of the piston 1-1 and onto the spring 19 thereby further compressingsaid spring. lVei-e the spring 19 not interposed between the piston l-l and the top 1l ot' the sleeve 8 it is obvious that jars and shocks occasioned by the moving contact ot' the shoe 1T with tbe roadway would be communicated directly to the' bracket 22 and thereby to the frame or chassis l and also to the operating,` lever 2* which might injure the arm of the operator were he holding said brake or lever QS. These jars and shocks are, however, absorbed by the spring 19 and thereby prevented from reaching the frame i of the operating lever 2S, which might otherwise injure and wrack said frame 4 and some ot' the mechanism attached thereto; loosening joints and otherwise damaging the Car. l

lVhile the device is in an operative position as above described the shoe 17 and tubular member 1 are prevented from moving backward by means of the rod 32 which 'connects the front end of Said shoe 17 with the. bracket 256 near the tront o'i' the Jframe Jr. The tubular member 1 and shoe 17 slidably mounted therein are also supported against lateral movement, due to the skidding movement, by means ot the lateral or side braces 7. Any vibration ot a violent nature due to the contact ot' the shoe 17 with the roadway will be readily taken up by means ot the connecting links and also by means of the flexibility of the bracket 36.

lt is obvious from the foregoing that I have provided an improved antiskidding` device that is adapted to prevent skidding and also means whereby the shocks and jars caused by such skidding will be absorbed bet'ore reaching the frame and the operating lever 28.

I'am. aware that the present state of the art discloses anti-skidding;` devices comprising a vertically reciprocatinglr member adapted to engage a roadway and thereby retard a forward or lateral niovement of a vehicle to which they are attached. I therefore do not wish to claimA such a combination broadly but lVhat I do claim as new land desire to Se cure by Letters Patent is- 1. An antiskidding device for motor vehicles and the like comprising a vertically disposed tubular member pivotally mounted upon the trame of'a vehicle; a 'vertically reciprocating shoe slidably mounted within the tubular member; means operatively connected to the shoe and adapted to lower the same into contact with a. roadway; resilient shock absorbing;r means interposed between the shoe and the operating means therefor; and a suitable rod operatively connected to the shoe and to the front cnd ot the vehicle and adapted to prevent a backward movement ot said shoe when the saine is in contact with the roadway.

2. An antiskiddingdevice for motor vchiolcs and the like comprising' a vertically disposed tubular member pivotally mounthicles and the like comprising a vertically disposed Itubular member pivotally mounted upon the frame of a vehicle; a sleeve slidably mounted within the tubular member and having a closed upper end thereto; a shoe slidably mounted within the sleeve; a suitable spring interposed between the top Aof the shoe and the closed end ot' the sleeve; and a suitable lever pivotally mounted upon the vehicle and operatively connected to the sleeve whereby the same may be raised or lowered and the shoe brought into contact with a roadway.

4. An antiskidding;` device for motor vehicles and the like comprising' a vertically disposed tubular member pivotally mounted upon the i' 'ame of a vehicle and having longitudinal slots in the sides thereof; suitable braces pivotally mounted upon the' frame with the/.tubular member and adapted -to brace the same laterally; a sleeve slidably mounted within *the tubular member and having the upper end' thereof closed and lateral lugs thereon projecting through the slots in the tubular'mcmber; 'a shoe having.,r longitudinal grooves on the, lower surface thereof slidably mounted within the sleeve; a suitable spring; interposed between the top of the shoe and the closed top of the sleeve; and a suitable lever pivotally mounted upon the frame and loperatively connected to the` sleeve whereby the same may be lowered and thereby bring'the shoe into contact with a roadway. n
