This invention relates to skis and has for its main object to provide a novel and efiicient device to aid the user of such skis in climbing hills or in general when ascending.

Another object of this invention .is to provide a device as characterized hereinbefore which may easily, quickly and conveniently be put out of operation when the user of the skis is descending, or proceeding on more or less level ground, while othe device will remain ready for a quick change and in a position to be again useful in case an ascending is necessary.

Other objects of this invention will be apparent as the specification of the same proceeds, and

among others I may mention: to provide a device was proposed to treat the lower or running surfaces of the skis with a special wax, or, leather, pieces of fur, or other devices have been applied to said running surfaces to increase the frictional resistance. All these devices and means required certain experience and skill, or they were awkward and cumbersome mechanical devices causing a great amount of labor, trouble, and consuming valuable time on ski voyages. This was especially the case in such voyages in which alternately ascending and descending stretches were included. The final result was that the skier either abandoned all such aids or was greatly hindered through such devices in his travel.

I also am aware that various mechanical devices have been applied to skis for the purposes mentioned hereinbefore, but it is a common knowledge that their operation was very unsatisfactory, and they also were apt to cause trouble and annoyance, and ultimately they were rather a hindrance than an aid.

All these drawbacks of the older devices have been eliminated by my device which is the subject of the present invention, and my invention enables a skier to apply on his skis, and at any time and as often as he desires, and in a quick, convenient and secure manner, a device which will aid him in ascending even quite steep hills with the least possible effort, and which device 55 after the ascent may again be in a similar easy and quick manner put out of operation so as not to obstruct the further travel.

My invention mainly consists in .a gripor wedge member which may easily be applied underneath the running surface of the ski ina transverse direction thereto, and which at any time may be as easily taken off from the same, and which wedge or grip will be of such a design and height that it will provide a secure grip and stopping action in all kinds surface of snow.

The wedge or grip and its securing means are of such construction that when it is desired to put said grip out of operation the same may easily and quickly be entirely taken off the ski 15:1

and carried in a bag or in a pocket of the skier, or it may simply be secured on the upper surface of the ski.

In the drawing forming a part of this specification and accompanying the same:

Fig. 1 is a side elevation of a ski to which my invention has been applied;

Fig. 2 is a fragmentary side elevation of the center portion of the ski shown in Fig. 1, on a larger scale, showing my device applied thereon in an operative position,

Fig. 3 is a similar side elevation showing my device on the upper surface of the ski in an inoperative position, and

Fig. 4 is a fragmentary plan view of the center 30 portion of the ski ona larger scale showing my device applied thereto, the wedge or grip portion thereof having been removed.

Referring now to the drawing more closely by characters of reference, the numeral l0 indi-. cates a ski on the upper surface whereof is applied in about the center 'of the same a plate member forming a generally semi-circular sleeve ll transversely to the ski l0, and being secured thereon in any convenient manner as by the 40 screws l2.

Journaled in the sleeve II is an upper transverse member or branch l3 of a rectangular frame, generally indicated by the numeral I,

having righthanded and lefthanded side mem- 45 here l5 and I6, respectively, and a lower transverse member l'l.

Normally the frame I4 is in the position indicated in Figs. 1 and 2, its lower member I! being underneath the running surface of the ski at a desired distance thereunder and transversely thereto, and on said lower transverse member I! is applied the operating element proper of my device being in the form of a grip or Wedge l9,

preferably having a pointed gripping edge 20, a

and conditions of 15 I6 may be 10 end 26 of the upper transverse member I3. For

better securing said flattened end 26 in said slot 25 a nose or projection 21 may be formed on the termination of said flattened end 26, as shown in Fig. 4. The outer end of the left side member screw threaded as at 28, and engaged by a wing nut 29.

The use and operation of my device will be obvious from the herein description.

When it is desired to use my device for ascend- 20 ing, the same will be placed in the position shown in Figs. land 2, and the wing nut 29 will be tightly drawn, thereby securing the wedge or grip I9 on the under side of the ski, and enabling same to grip the snow, aid in the ascent, and prevent 2i backward slipping.

When again it is desired to put my device out of operation, the wing nut 29 will be released, the left hand side member It opened around the pivot 24, the member lfl pulled out of the sleeve II,

30; thereby removing my device from the ski, whereupon the grip or wedge member I9 will be placed on the upper surface 30 of the ski as indicated in Fig. '3', the member I3 replaced in the sleeve I I, the

sidemember I6 closed thereon, and the wing nut 353 29 tightened. My device is now firmly secured in the position indicated in Fig. 3 permitting an unhindered sliding of the ski. 1

I preferably place my device in front of the usual foot rest, or foot plate 3 I, and foot securing means 32 of the ski, and in the inoperative position thereof shown inFig. 3 the same may be helpful in protecting the foot from the snow.

It is obvious that my device may be entirely taken off the ski, in the manner described here- 'inbefore and instead of replacing it thereon in the inoperative position of Fig. 3, the frame and for arranging and securing the grip member proper I9, or narrower ring-like members, or other projections may be employed instead of the sleeve I I, the shape and proportions of the grip member I9 may be changed and, instead of such a member, several of them may be employed or even individual teeth, pins, or the like, while of course they appear to me to be less advantageous than the form here shown. In a similar manner the application, the removal, and the securing of the grip member I9 may be arranged in various other manners than the one here shown.

What I claim as new, and want to protect by Letters Patent, is: l

A climbing device for skis, comprising a sleeve member transversely secured on the upper surface of the ski, a frame member being composed of an upper transverse element across said upper surface arranged in said sleeve, a first downhanging side element at one end of said upper element, a lower transverse element underneath the ski, and a second side element pivoted on the free end of said lower transverse element, a releasable connection between the free ends of said upper 38 transverse element and said second side element, of said frame respectively, a grip member secured on said lower transverse element having a base surface adapted to rest against the lower surface preferred of the ski and a pointed end opposite thereof, said upper transverse element being adapted to be moved out of, or into, said sleeve element by a sliding motion when said connection is released and said second side element is turned below the lower surface of the ski on its pivoted connection with 5 the lower transverse element.
