Patented Aug. 16, 19 38 UNITED STATES SHOE HEEL Richard F. Hoflin, Flushing, Long Island, N. Y., assignor to Webwood Corporation, New York,
Application April 23, 1937, Serial No. 138,489
1 Claim.
This invention relates to new and useful improvements in methods and means for making shoe-heels, whereby the latter will have imparted to them a very great tensile strength.
5 Ordinarily such heels have been made from a mixture of adhesive coated fibres, or leather pieces obtained from sole leather scrap by cutting up the latter in pieces of a definite size and form, for instance of one square inch, and after 10 a further preparation and treatment commingling said pieces, or particles together by means of suitable adhesives, whereupon a predetermined pressure in turn is applied to said mixture with the result that upon use of a suitable form a 5 shoe-heel, for instance, is turned out.
It is the object of the present invention to improve upon especially the shoe-heel thus produced in the above manner, to the end and extent of obtaining a shoe-heel of a tensile strength many times greater than the one made in the manner referred to above, and at, what may be considered but a negligible additional manufacturing cost.
With the above and other objects in view, 25 this invention consists of the novel features of combination, construction and arrangement of parts hereinafter fully described, claimed and illustrated in the accompanying drawing forming part of this application, and in which similar characters indicate corresponding parts, and in which:
Figure 1 is a somewhat perspective view of my invention, showing the latter in the process of making.
35 Figure 2 is an end view of the figure shown in Figure 1.
Figure 3 is a similar View of my invention in its finished stage; while Figure 4 is a transverse sectional view of my 40 invention, taken on the line 4-4 in, Figure 3.
' Referring more particularly to the drawing, l indicates a filler made from adhesive coated leather fibres, or pieces of a definite size and shape of sole leather scrap, coated with a suitable 45 adhesive by means of mechanical agitation.
After said filler has attained the form shown at In in Figure 1, and while still materially in a state susceptible to further molding, said filler, coated with an adhesive, is arranged between two lifts H and I2, consisting of split sole leather, 5 and then molded under a pressure from 4,000 to 6,000 lbs. per square inch.
The upper lift II is slightly larger in circumference, for instance one sixteenth of an inch, than the lower lift l2, in order when pressure is applied upon the parts combined, then to take up the conventional curvature l3, of which an imprint has already been made upon the unfinished filler II].
By thus arranging said lifts II and I2 upon the filler, as shown, and integrally combining said parts together by means of an adequate pressure, a heel of great tensile strength will be provided.
As a suitable adhesive for coating the leather fibres or pieces, cellulose acetate or nitrate in acetone may be used; or adhesives made from animal or vegetable glue or a combination of latex and glue or casein with or without any of the other herein mentioned substances may be used.
It is obvious that changes may be made in the construction, combination and arrangement of parts within the scope of the appended claim, and without departing from the spirit of the invention; and I do not therefore wish to limit myself to the exact construction shown and described herein.
What I claim as new and desire to secure by Letters Patent of the United States, is:
A method of forming a shoe heel comprising providing a base and top lift of leather, and a filler, the base being one-sixteenth of an inch larger in circumference than the filler and top lift whereby when subjected to pressure the base assumes the conventional curve without great distortion, and assembling top lift filler and base, and subjecting these parts to pressure to produce a heel.
RICHARD F. HOFLIN.
