4 Claims.
My present invention relates to calk sole structures'for shoes and like foot-wear and to a novel shoe calk for such articles. 1 Calk soled shoes are used for a great variety of purposes, but popularly for athletic wear in such sports as require firm footing and the prevention of any slipping or even tendency to slip. As such wear is by nature vigorous it becomes frequently necessary to replace calks because of breakage or dulling or where the shoe is desired to be packed, stored or even worn without the projecting calks.
A great variety of calks have been devised and some of them of detachable nature, but most of these have been of complicated structure and have necessitated bothersome individual hand operations is setting them in the sole.
My invention contemplates a new calk sole structure and a new calk which makes production possible by machine setting operations and which greatly facilitates the production of the shoe and at the same time produces a greatly improved sole structure both as to wearing qualities and as to convenience in the attachability and detachability of the calk points.
As illustrative of my invention I have shown embodiments which indicate the principles involved and at the same time provide simple, effective, inexpensive structures and operations. Throughout the specification and drawing, like reference numerals are employed to indicate corresponding parts, and in the drawing:
Fig. 1 is a partly sectioned view of a shoe structure such as is involved.
Fig. 2 is a sectional detail of the calk in place.
Fig. 3 is a sectional detail of the tubular sole member.
Fig. 4 is a side view of a calk to be used therewith.
Figs. 5 and 6 are face views of the interengaging collar members, and
Figs. 7 and 8 are views of similar calk members having radially flanged engagements.
In providing such a calked sole this invention contemplates a two part calk member. One part indicated as at 1 consists of a tubular sole piece 1. As shown in diagram this has a flange 2 at one end adapted to abut the outer surface of a. sole S, but said flange may be otherwise formed or omitted. At its inner end 3 it is outwardly tapered or flared so that the portion may be sprung or outwardly spread to clinch the member as shown in Figs. 1 and 2. Internally as at 4 the member 1 is threaded to receive the calk. Preferably it may carry a shoulder at the bottom of the tapered portion to prevent the threaded portion from being deformed during the process of clinching.
A calk member, Fig. 4, consists of a point 10 having a threaded shank 11 and a flange 12. 30 These flanges 2 and 12 are to be interlocked upon the screwing up of the calk and sole members as shown in Fig. 2. The interlock may be variously effected as by projections 13 and recess 5 as in Figs. 3 t0 6. 5
In Figs. 7 and 8 a modified form of calk is shown in which the sole member 151s provided with a flange 16 having serrations 1'1. These cooperate with similar serrations 18 on the flange 19 of the calkmember 20. The flanges in this case, as in the previously described form yield slightly upon engagement thus permitting an interlocking of the serrations.
The tubular sole members 1 may be set in the soles S as by a standard eyeletting machine. The calks may then be screwed in place until the flanges interengage. Such calks afford a very practical basis for factory operation and make possible a much improved sole structure.
The calk points may be given any desired form or length and as they may be easily removed or substituted give greatly increased utility to the shoe. The points may be pyramidal as indicated in Fig. 4 or conical as in Fig. 8. The pyramidal form is convenient as it affords a grip for a wrench or spanner but flattened faces may be provided in any form.
What I therefore claim and desire to secure by Letters Patent is:-
1. A calk assembly for shoe soles comprising a member to be inserted through an opening in the sole, an outwardly directed flange on said member for engagement with the outer face of the sole, means for fastening said member within the opening in the sole with the flange thereof engaging the sole, a calk having a screw threaded connection, and a flange on the calk to overlie the flange of the member when the calk is operatively connected with the member, one of said flanges having a projection and the other a recess to accommodate said projection to lock the calk against unscrewing from the member when the calk is operatively connected with the member, at least one of said flanges being yieldable to permit engagement of the projection with the m5 recess by threading of the calk onto the member.
2. A calk assembly for shoe soles comprising a one-piece tubular member to be inserted through an opening in the sole, an outwardly directed flange on the outer end of said member for enno gagement with the outer face or the sole, the inner end portion 01' said member being formed to be deflected outwardly and clinched against the inner face of the sole, saidmember having interior screw threads, a calk inclusive of a point portion and a threaded shank to be screwed into said tubular member, a lateral flange extending from said calk to overlie the flange of the tubular member, and cooperating projection and recess formations on said flanges,'respectively, rendered effective by screwing oi the shank of the calk into the tubular member to lock the calk against accidentally unscrewing from said tubular member, at least one of said flanges being yieldable to permit interlocking engagement of said formations.
3. In a shoe structure, a sole and a calk assembly including a tubular insert comprising a sleeve having a flanged outer end, said sleeve having at its inner end a tapered portion expansively crlmped into the inner surface of the sole, said sleeve being threaded internally toward the tapered portion, and a detachable calk with a threaded shank engaging said sole member and having an external flange compressibly reinforcing the insert and adjacent sole structure and serving to lock the calk to the sleevemember and to the sole.
4. In a shoe structure, a sole and a calk assembly including a. tubular insert comprising a sleeve having a flanged end, said sleeve having at its other end a tapered portion expansivelycrimped into the material of the sole, said sleeve being threaded internally toward the tapered portion, and a detachable calk with a threaded shank engaging said sole member and having an external flange compressibly reinforcing the insert and adjacent sole structure and serving to lock the calk to the sleeve member and to the sole.
