Thereby said inner shell is enabled to revolve with n said chamber, said two half shells being maintained adjacently due to their enclosure within sa d chamber ZI. The diameter of each the diameter of said split inner shell I9.

A portion of said ski pole II protrudes through said aligned openings 26 of said inner shell I9 and is frictionally engaged by said aligned flanges 21. Since that portion of the ski pole is substantially cylindrical, it fits well into said cylindrical flanges 21, and the taper of said ski pole together with the particular diameter of said openings 26 determines the location of said ski pole ring IE on said ski pole II, when secured thereon.

Said ski pole II protrudes at opposite sides from said inner shell I9 through said apertures 22, and said pole may be moved with relation to said outer shell I8 within the surface 01 a cone; this is best shown in Fig. 4, where the two extreme angular tilting positions of the ski pole with relation to the outer shell I8 is shown. Thereby, the tilting relation of the ski pole with relation to the ski pole ring I 2 is substantially defined. However, an additional tilting of the ring with relation to the pole may be brought about through flexing of the straps I6, since the latter are made of leather or similar flexible resilient material.

Said outer shell I8 is composed of two symmetrically arranged sections 28, each carrying an integral annular flange 29 arranged about equatorially of said outer shell I8. Said two flanges are in abutment in a plane substantially midway between said two apertures 22. Said outer shell I8 is thus made of two sections, primarily for the purpose of facilitating the assembly of said swivel clamp l3.

Said flanges 29 are provided with a plurality of holes 3| and are held together by means of rivets 32 located in said holes 3|. Said rivets 32 at the same time also pierce said centrally projecting ends of said straps I6 and thus secure said swivel clamp I3 within the center of said ring I2. However, the outer rims of said flanges may also be welded or brazed together, thereby uniting said flanges into a single flange of a single one-piece outer shell.

For mounting, two half-shells 23 are enclosed within two abutting sections 28, the holes 3| thereof aligned and the rivets 3| inserted therein and in pre-punched holes of the inner ends of said straps I6. Thereafter, the rivets are secured, and the ring I4 riveted onto the outer radially spaced ends of said straps I6, by means of rivets I1. Then, the split inner shell I9 is revolved in said chamber 2| until an opening 26 is visible within each aperture 22 and subsequently the ski pole I I is inserted into the openings 26, by aligning them and frictionally engaging the inner walls of said flanges 21.

Due to the slight tapering of said ski pole II, the inner ends of said flanges 21 will be slightly deformed according to the adjacent diameter of the ski pole part therein and thus, a strong frictional engagement intermediate said swivel clamp I3 and the ski pole part therein is assured.

Certain of the advantages of the invention have already been herein referred to. It may be useful, however, to allude particularly at this point to the great facility with which the swivel clamp I3 and the entire ring I2 may be assembled, and the ease and simplicity lent toward frictionally securing the swivel clamp 83 to the ski pole II.

I do not limit myself to the particular details of construction set forth in the foregoing specification and illustrated in the accompanying drawings, as the same refer to and set forth only one embodiment of the invention and it is obvious that the same may be modified, within the scope of the appended claims, without departing from the spirit and scope of the invention.

It is accordingly desired that in construing the breadth of the appended claims, they shall not be limited to the specific exempliflcation of the invention described herein.

Having thus described the invention, what I claim as new and desire to be secured by Letters Patent, is as follows:
