COMPOSITION SHOE HEEL'AND METHOD MAKING THE SAME.
Application led August 1, 1921. Serial No. 488,974.
This invention relates to shoe heels, and more particularly to heels of the composition type. l
One of the objects of this invention is to b provide 'a shoe heel which possesses the required strength, which can be readily attached to the shoe, which is adapted to receive a high finish, and to which the leather of the shoe sole can be readily attached.
Another object of this invention is to provide a process or method for making such a heel.
Further objects will appear from the detail description taken in connection with the accompanying drawing in which the figure is a cross-section of a shoe heel embodying this invention.
The shoe heel elnbodying this invention comprises a body 1 of plastic material and a coating 2 which is combined therewith to form a composite mass. In the case of high A heels, a core 3 is provided in order'to secure the desired strength' and this core extends from the seat to thetread., The core is formed of wood or any other suitable Inaterial which is adapted to be penetrated by a fastener'` such as a nail or la screw. The body l is a rubber composition and is preferably formed of a ligneous materialwhich is mixed and vulcanized with the rubber.
In the particular embodiment of this invention the body comprises saw-dust, cork and raw rubber in the roportion of about seventy-tive per cent (E570) of saw-dust, five per cent (5%) of cork and twenty per cent of raw rubber. The coating 2 is of'hard rubber which `is vulcanized on the body., y
In accordance with theprocess embodying this invention the saw-dust, cork and -raW rubber are mixed and placed in a mold around the core and the body is then molded under pressure While subjected to a vulcanzing heat. This may be accomplished in any suitable vulcanizing mold which, as usual, may be heated by steam. It will, of
course, be understood that a suitable'amount I ofsulphur may be added to the mixture to secure proper vulcanization of the body.
The body being formed to shape is now coated with alayer of hard rubber; this may be accomplished by forming a hard rubber sheet (made in accordance with any suitable hard rubber formula) around the formed body; the coated body is then placed in a mold and again subjected to pressure at a vulcanizing heat, whereby the coating Will not only run together to form a Continuous surface covering but Will also combine With the body to form a composite 00 mass.
Where the heel is provided With a top lift I which may be attached to the bod-yv by any l i suitable fastener, such as a nail 5 driven into the core, it will be unnecessary to coat the body tread; furthermore it will be unnecessary to coat the seat 6 of the heel. Moreover where as is often the case especially in high heels the sole is pasted against the breast 7 of the heel, it will be unnecessary to cover this breast. It will be understood, therefore, that the covering is applied to such faces as may be necessary to meet the requirements and to adapt the heel to the uses as desired.
Itvvill, therefore, be seen that the invention accomplishes lits objects. A heel is provided Which is a composite mass. The body of the heel not only has great strength but the required density and lightness on account of the large proportion of saw-dust used in its manufacture. This body moreover is adapted to receive the nails or other fastening means and on account of the intimate mixture of the components of the vulcanized body and the nature of the vulcanized miX- 35 ture, it is adapted to firmly retain the nails or other fastenings which may be used. In lo\v heels, therefore, it is unnecessary to use the core since the fasteners may be driven .directly into the composite vulcanized heel body. Moreover the body is of such a nature that it will readily take cement. Accordingly the heel can be conveniently cemented to the shoe; this characteristic is especially advantangeous in that it permits the flap on the sole to be cemented against the heel breast as is usual in wooden heel constructions. The coating not only forms a hard protective covering but also one which is adapted to receive a high polishand presents a neat appearance. p
It Will be noted that the core 3 terminates a short distance below the seat of the heel thereby providing an open recess 8. This makes the struct-ure resilient since the body will give slightly when the Weight of the foot comes onV the heel, which resiliency is. desirable' in heel constructions.
It is obvious that various changes may be made in details of construction Without no vl. A shoe heel, comprisin a vulcanized mixture of sawdust, cork an rubber.
2. A shoe heel, comprising, a body of plastic material having'a core extending from its 4seat to its tread, and a coating combined therewith to forma composite mass.
3. A `shoe heel, comprising, a core, and a composition body of rubber and granular material vulcanized on said core.
4. A shoe heel, comprising, a core, a body of rubber composition vulcanized on said core, and a coating of rubbervvulcanized on said body.
'5. In the art of making shoe heels, the process comprising, moldin a body of plastic material, coating the bo y with hard rubber, and molding the coated body While subjected to a vulcani/zing heat.
6. In the art of making shoe heels, the process comprising, molding a body of plastic material While subjected to a vulcanizing heat, coating the body with hard rubber, and molding the coated body While sub jected to a vulcanizing heat.
In testimony whereof I aix my signature tliis`19th day of July, 1921.
