3 Claims.

My invention relates to improvements in traction devices for skis, the principal object in View being to provide a simply constructed, inexpensive device adapted for quick and easy attachment to a ski whereby hill and mountain grades may be safely and easily climbed on skis and serious accidents thereby prevented.

Other and subordinate object are also comprehended by my invention, all of which, together with the precise nature of my improvements, will be readily understood when the succeeding description and claim are read with reference to the drawings accompanying and forming part of this specification.

In said drawings:

Figure l is a view in plan illustrating my improved traction device applied to a ski, the latter being shown in dotted lines,

Figure 2 is a view in side elevation of the ski shown in full line,

Figure 3 is a view in transverse section taken on the line 3-3 of Figure 1,

Figure 4 is a similar view taken on the line 4-4 of Figure 2,

Figure 5 is a view of the blank from which the traction member is formed.

Referring to the drawings by numerals, my improved traction device, in its preferred embodiment, comprises, as its primary element, a substantially rectangular clamping plate I, of suitable resilient, metal, and having a flat bottom 2 and right angled, uptmrned, parallel sides 3 adapted to fit alongside opposite side edges of a ski 4 so that the clamping plate may be applied upwardly to the ski 4 to straddle the same with the bottom 2 of said plate opposed flat against the bottom 5 of said ski. A pair of vertical slots 6 are provided in the sides 3 of said plate. A bolt 1 i provided for extension through said slots 6 and across the ski 4, with a wing nut 8 threaded on One end thereof, whereby when the nut 8 is tightened the sides 3 of said plate may be clamped against the side edges of the ski 4.

In the rear of the clamping plate I is a similarly shaped traction member 9 having a fiat bottom l and right angled sides ll provided with a pair of forwardly extending front end ears I2 straddling the sides 3 of the clamping plate I and pivoted to said sides, as at l3, adjacent the rear ends of said sides 3 so that the bottom ll] of said member 9 may be engaged flat with the bottom of the ski 4 by upward swinging of said member, and the member is free to drop downwardly on the pivot l3. The bottom of the member 9 is provided with a transverse row of downturned, rearwardly extending teeth l4 for biting into ice, snow, or the ground, as the case may be.

As shown in Figure 5, the member 9 may be formed from a metal blank l5 shaped to provide the ears l2 and the sides II when the blank is bent upwardly along the dotted lines I6. Although it has been stated that the plate I and member 9 may be formed of metal, other material such as plastic or composition may be utilized.

For climbing a grade, with skis, the described device is applied in the manner already set forth, one to each ski, at a suitable point intermediate the ends of the ski, so that in climbing, the teeth l4 will bite rearwardly and downwardly into the ice,- or snow, or ground, and thereby prevent the ski from slipping rearwardly. In case the ski is placed on uneven surfaces, for instance, with opposite ends on raised mounds, or the like, the traction member 9 will drop downwardly on its pivot l3 to dig into the low spots or areas between such mounds and thus provide for adequate traction on uneven surfaces. The device may be quickly detached by merely removing the bolt 1, and carried on the person until required.

The foregoing will, it is believed, suffice to impart a clear understanding of my invention with out further explanation.

Manifestly, the invention, as described, is sus-. ceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claims.

What I claim is:

1. A traction device for use on a ski comprising a clamping plate of resilient metal having a flat bottom and sides adaptin the member to fit upwardly on a ski with said sides straddling the ski and extending above the same, and said bottom opposed flat against the bottom of the ski, said sides having vertical slots therein, a bolt for extension through said slot and acros the top of the ski and provided with a nut for clamping said sides to the side edges of the ski, and a traction member pivoted on said clamping plate to trail the same and for vertical swinging thereon, said member underlying the ski.

2. LA traction device for use on a ski comprising a clamping plate of resilient metal having a fiat bottom and sides adapting the member to fit upwardly on a ski with said sides straddling the ski and extending above the same, and said bottom opposed flat against the bottom of the ski, said sides having vertical slots therein, a bolt for extension through said slot and across the top of the ski and provided with a nut for clamping said sides to the side edges of the ski, and a traction member pivoted on said clamping plate to trail the same and for vertical swingin thereon, said member underlying the ski and having forwardly extending ears straddling the sides of said clamping plate and pivoted thereto.

3. A traction device for use on a ski comprising a clamping plate of resilient metal having a fiat bottom and sides adapting the member to fit upwardly on a, ski with said sides straddling the H) ski and extending above the same, and said bottom opposed fiat against the bottom of the ski, said sides having Vertical slots therein, a bolt for extension through said slots and across the top
