Nutt, Beverly, Mass, assignor to , United Shoe Machinery Corporation, Paterson, N. J., a corporation of New Jersey Application May 28, 1937, Serial No. 145,319 6 Claims. (01. 12—147) 'This‘invention relates to the manufacture of shoes and is-illustrated as embodied in a novel heel and with reference 'to improvements in covering the same. 01 Inv covering wood heels of the Louis type, it is common practice to coat the edge portions of the heel with pyroxylin cement and then to ap ply a Celluloid cover, which has been activated by~a suitable solvent, to the rear and side faces 10 of the heel, the forward projectingmargins of the cover being inturned on and secured to the \lateral margins of the heel breast. In view of the fact that the leather heel-breast-covering flap of the shoe to which the heel is attached cannot be effectively secured to the inturned mar gins of the Celluloid cover on the heel breast through the use of rubber cement, which is bet ter adapted for this purpose than pyroxylin cemenhand in order to‘ prevent the formation 20v of ridges in. the heel breast of the finished shoe where the heel-breast-covering ?ap overlies the edges of’ the inturned margins of the Celluloid cover, it is common practice totrim the inturned margins of the cover ?ush with corresponding 25 breast edges of the heel after the’ cover has ‘dried portions of the inturned margins‘of the cover secured in therecesses. The inturned margins of the cover which are secured Within the recesses serve to counteract the above-mentioned tend ency of the cover to pull away from the forward The'various features of the invention will be understood and appreciated from the following detailed description, read in connection with the accompanying drawing. 10 In the drawing, Fig. 1 is a perspective view of an uncovered wood heel of the Louis type having in the lateral margins of its breast a plurality of spaced recesses intersecting corresponding sides of the heel, the margin of the attaching face of the heel being provided with a plurality of recesses which termi nate at the rim of said attaching face; Fig. 2 is a perspective view of the heel of Fig. 1 in the process of having its cover applied; Fig. 3‘illustrates the heel of Fig. 2 after its cover has been applied, in the process of having the forward margins of said cover trimmed flush with the breast edges of the heel, leaving por tions of the cover which are secured within the 25 thoroughly and‘before attaching the heel to the recesses formed within the breast, secured to the shoe. heel; After the heel has been attached to the shoe, the heel-breast-covering flap is secured ‘to the breast of the heel by the use of rubber cement. When heels are covered as above described, it hasfbeen found that the Celluloid cover of the ?nished shoe frequently breaks away from the sides of. the'heel along its breast edges. Such defect maybe the result of the wearer sliding 35 ' the breast edges of the heel of the shoe along rungs of chairs or other objects, or may be caused by the failure of the operator properly to coat the entire edge portions of the heel with pyroxylin cement before attaching the Celluloid cover to 40 the heel.' In order to overcome the above-mentioned de feet in Celluloid-covered heels, I have provided a heel having in each lateral margin of its breast a plurality of shallow cover-receiving recesses which are spaced from each other and intersect a corresponding side of the heel. In order to secure the activated Celluloid cover to the heel, the operator applies a ?lm of pyroxylin cement to the edge portions of the heel and, after apply ing the cover to the rear and side faces of the heel and forcing the forward projecting margins of the cover against the lateral margins of the‘ heel breast and into the recesses formed in the‘ breast, trims the inturned margins of the cover flush with the breast edges/of the heel, leaving 5 margins of the sides of the heel. Fig. 4 is a section on the line IV--IV of Fig. 3, and Fig. 5 is a plan view showing the attaching 30 face of the heel after the top inturned margin of the cover has been trimmed, leaving portions of said margin secured in the recesses formed in the margin of the attaching face. The invention is illustrated with reference to a 35 wood heel 20 of the Louis type to which a Cellu loid cover 22 (Fig. 4) is to be applied. The lateral margins of the breast 24 of the heel are provided with recesses 26, each of which intersects a cor responding side of the heel and has a depth 40 not greater than the thickness of the cover 22. The margin of the attaching face of the heel is provided with a plurality of spaced recesses 28, the outer ends of which terminate at the rim 30 45 of the attaching face 32 of the heel. reparatory to attaching the cover 22 to the heel, the marginal portions of the heel which are located adjacent to the breast edges 34 and the rim of the attaching face 32, including the recesses 26 and 28, are cement. After the cover in a bath of acetone or it is applied to the rear coated with pyroxylin 50 22 has been activated other suitable solvent, and side faces of the heel, the forward projecting margins 36 of the cover being inturned upon and secured to the 55 2 2,135,673 lateral margins of the breast 34 and also being forced into the recesses 26. The top margin 38 In order to insure that the breast of the heel of they ?nished shoe shall havea shape substan (Fig. 2) ‘of the cover may be inturned upon and tially the same as that of the uncovered breast secured to the margin of the attaching face 32 of the heel, leather covers or covers of'various of the heel, including the recesses 28, While the other materials may be advantageouslyapplied margins 36 are being applied to the heel breast, to heels in the manner above described in con or may be applied to the attaching face of the nection with Celluloid covers. 7 , g ' heel either before or after applying the forward Having described my invention, what I claim 10 margins to the heel breast. The cover may be applied to the heel by hand or by the use of the machine disclosed in Letters Patent of the United States No. 2,119,840, granted June 7, 1938 on an application ?led in the name of Lewis J. Bazzoni. Covers applied to heels by the use of the above 15 mentioned machine are forced by a rubber pad 20 as new and desire to secure by Letters Patent of A heel having in each lateral margin of its breast a plurality of shallow cover-receiving re cesses which are spaced from each other and in- , tersect a corresponding side of the heel.

Brostrom, leaving the edges of the heel. portionsor tabs 40 (Figs-3 and 4) of the in turned margins 36 secured within the respective recesses 26. The construction of the above-men tioned machine, which comprises a band knife 35 (Fig. 3)‘, is fully disclosed in said Letters Patent No. 1,834,677. r r 7 ~ 35 After the top margin 38 of the, cover 22 has i been inturned upon and secured to the attach ing face 32 of the heel, it is trimmed by the use of a hand knife or themachine disclosed in the ' above-mentioned Letters Patent No. 1,834,677, 401 just within the rim of the attaching face, the portions of the margin or tabs 42 (Fig. 5)nsecured 'within the recesses 28 being left in order to'in-‘ sure that the cover will be held securely in place’ on the rim 30 of the attaching face 32 during 45 the life of the shoe to which the heel is attached. By providing the tabs 42, it is possible to trim the inturned top margin'38 of the cover just, within the rim 3!] of the attaching face, thereby 50 exposing substantially the entire attaching face of the original wood heel for heel-attaching pur poses. V The recesses 26 and 28 are preferably cut to a depth slightly less than the thickness of the cover, which is stretched slightly during’ its ap 55 plication to the heel, the tabs .40 being trimmed flush with the breast of the heel' to insure that no depression will appear in the heel breast of the ?nished shoe. 41'.
