9 Claims. (c1. 2s011.37)

'My invention relates to improvementsin sleds for use more particularly by trappers, ski-troop- .ers, and the like, for transporting load packs over frozen trails, rivers, and snow-covered ground.

The primary object of my invention is to provide a light-weight, strong sled utilizing a pair of skis as runners, and ski poles as load supporting devices and pusher members, and which is adapted to be easily and quickly taken apart when it is desired to use the skis and ski poles as such.

Another object'is to provide a sled characteriz'ed and for the purposes as above set forth, and

which is adjustable as to width, involves a minimum number of parts in excess of the skis and ski poles, which may be easily packed and carried on the person using the skis and poles in the'usual manner, and which is safe and forms inexpensive equipment for transporting heavy loads..

Other and subordinate objects 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 claims are'read with reference to the .drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a view in side elevation illustrating my, improved sled in its preferred embodiment,

Figure 2 is a view in top plan,

Figure 3 is a view intransverse section taken on the line 3-3 of Figure 2, I

Figure 4 is a view in perspective of the bridging frame,

Figure 5 is a view fled embodiment of my improved sled, 1

Figure 6 is a view in top plan of the same, and I Figure 7 is a detail view in vertical transverse section taken on the line 1-1 of Figure 5.

Referring to the-drawings by numerals, and first to Figures 1 to 4 thereof, in the preferred embodiment of my invention, a pair of the usual skis I, 2 are detachably connected together in side-by-side, parallel, laterally spaced relation to form runners and by means of a skeleton bridging frame 3 extending across the tops of the skis I, 2 in upright position, in substantially the transverse center of the skis, and a tie bar 4 extending across the tops of the toes 5 v of said skis.

The bridging frame 3 comprises a flat base bar 6 of suitable light metal providing end portions 1 extending flat across the tops of the skis I, 2

and adapted to project beyond the side edges of said skis for a short distance and an upwardly bowed center portion 8 between said end portions I. A pair of side uprights 9 arise from theend portions I directly over the skis I, 2 and which are of angle iron form, and suitable netal, with one flange Ill facing forwardly and the upper ends of said flanges concaved to form sockets for a purpose presently seen. The uprights 9 are formed, preferably, integrally with the end portions 1. A pair of diagonal brace rods II extend between the upper ends of the flanges II), in a common plane with said flanges, to the upper face of the bowed portion 8, and

.are crossed in the vertical center of'the frame 3 to provide a crotch I2 below the concave upper ends ID of the uprights 9. The brace rods II are connected, as by Welding, not shown, to the flanges. III 'and to the bowed portion 8. The end portions I of the brace bar 6 are detachably attached to the side edges of the skis I, 2 as follows:

Each ski I, 2 is provided with a pair of pins I3 extending from the side edges thereof, respectively, laterally, and in substantially the 1 transverse center of the skis, and which are in side elevationof a modiformed with down-turned outer ends. A pair of eye bolts I4 are looped over each pair of pins I3 and extended upwardly through the overlying end portions 1 of said bar 6 with Wing nuts I5 thereon bearing against said end portions. The eye bolts I4 extend through longitudinal slots I6 in the end portions 1 of the base bar 6 to provide for adjusting the skis I, 2 laterally, relatively, so that the width of the sled may be varied. I 'The tie bar 4 is detachably connected to th toes 5 of the skis I, 2 by upwardly extending bolts I'I passing through slots I8 in said bar so that the skis I, 2 are laterally adjustable at the toe ends thereof, also. The heads 20 of the bolts Il may be countersunk in the toes 5 of the skis, and the bolts provided with jam nuts, as at 2|. A pair of eye bolts, or screws, 22 extend upwardly from each ski forwardly of the frame 6. A pair of side brace bears 23 extend downwardly and forwardly from the sides of the uprights 9 to said eye bolts 22 and are provided with front .therethrough of bolts 26 passed through suitable bolt holes, as at- 21, in said uprights 9, the bolts 26 being-also equipped with wing nuts 28.

Each eye bolt 22 carries a ring 29 swivelly disposed in the eye thereof, and for the insertion of the point of the usual ski poles 30 therein.

A pair of ski poles 30 may be inserted in the rings 29 with their points bearing on the skis I and 2, and the poles slanting upwardly and rearwardly and resting in the concave ends ID of the uprights 9 so that said poles provide pusher members for propelling the sled and also load pack sustaining members for supporting a load pack, as at 3|, interposed between the poles and resting in part in the crotch l2.

The uprights 9 are provided with upper end slots 32 through which a tie rope 33 may be extended to tie the load pack 3! onto the poles 3D and in the crotch I2.

In the modified embodiment of the invention shown in Figures 5, 6, and 7, a pair of front and

rear bridging frames

35, 36, similar to the frame 3, are utilized to connect the pair of skis 3T, 38 together, one frame being arranged between the transverse centers and toes of the skis, and the other adjacent to the rear ends of said skis. Side brace bars 39, similar to brace bars 23 extend between the side uprights 40 of said frames to eye bolts 4! on the skis arranged intermediate said frames. In this embodiment of the invention, the concave sockets 42 in the upper ends of said uprights 40 provide rests for a pair of longitudinally extending side poles 43, and the crossed diagonal brace rods 44, similar to brace rods, ll, serve to support in the crotches thereof a longitudinally extending lower center pole 45. As will be seen, by reference to Figures and 6, the poles 43 and 45 form a skeleton bed which may be utilized to support a load pack in elevated position above the skis 37, 38.

As shown in Figure 7, in the modified embodiment of my invention, the base bars 46 of the

frames

35, 36, have their ends detachably attachedto the

skis

31, 33 by a pair of bolts 41, the ends of which are countersunk in the bottom of the skis, and which are equipped with jam nuts 48 countersunk in the tops of the skis, and with wing nuts 49 for bearing against said ends. One bolt 41 of each pair extends through a slot :50 in the related ends of the base bar 46, said slots serving to compensate for manufacturing the skis.

As will be apparent, by detaching the frame 9, tie bar 4, ski poles 30, and brace bars 23, in the preferred embodiment of the invention, the skis l, 2 may be rendered available for use as such, together with the poles 3B, and the detached parts, together with the eyebolts l4, wing nuts l5, eye bolts 26, wing nuts 28, and the wing nuts It, may be packed ina small bundle for carrying as a shoulder pack. By detaching the frames 35, 3t, and other parts connecting the skis 31, 38 together in the modified embodiment of the invention, such parts may be compactly arranged within a small space for storage to permit the use of the skis and ski poles as such.

The foregoing will, it is believed, suflice to impart a clear understanding of my invention without further explanation.

Manifestly the invention, as described, is susceptible 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.
