'Thisinvention relates to the manufacture of shoes and is-illustrated as embodied in a novel heel and with reference 'to improvements in covering the same.

In 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 apply a Celluloid cover, which has been activated by-a suitable solvent, to the rear and side faces 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 margins of the Celluloid cover on the heel breast through the use of rubber cement, which is better adapted for this purpose than pyroxylin cemenhand in order to prevent the formation of ridges in. the heel breast of the finished shoe where the heel-breast-covering flap overlies the edges of the inturned margins of the Celluloid cover, it is common practice totrim the inturned margins of the cover flush with correspondingbreast edges of the heel after the cover has dried thoroughly andbefore attaching the heel to the shoe. 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 finished shoe frequently breaks away from the sides of the'heel along its breast edges. Such defect maybe the result of the wearer sliding 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 the heel.'

In order to overcome the above-mentioned defeet 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 film of pyroxylin cement to the edge portions of the heel and, after applying 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 portions of the inturned marginsof the cover secured in therecesses. The inturned margins of the cover which are secured Within the recesses serve to counteract the above-mentioned tendency of the cover to pull away from the forward 5 margins of the sides of the heel.

The'various features of the invention will be understood and appreciated from the following detailed description, read in connection with the accompanying drawing.

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 terminate 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. 3illustrates 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 portions of the cover which are secured within the recesses formed within the breast, secured to 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 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 wood heel 20 of the Louis type to which a Celluloid 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 corresponding side of the heel and has a depth 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 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 coated with pyroxylin 50 cement. After the cover 22 has been activated in a bath of acetone or other suitable solvent, it is applied to the rear and side faces of the heel, the forward projecting margins 36 of the cover being inturned upon and secured to the 55 lateral margins of the breast 34 and also being forced into the recesses 26. The top margin 38 (Fig. 2) of the cover may be inturned upon and secured to the margin of the attaching face 32 of the heel, including the recesses 28, While the margins 36 are being applied to the heel breast, or may be applied to the attaching face of the heel either before or after applying the forward 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 filed in the name of Lewis J. Bazzoni. Covers applied to heels by the use of the abovementioned machine are forced by a rubber pad (not shown) against the heel, the arrangement being such that the forward and top margins 38 and 38 of the covers are effectively secured within the recesses 26 and 28, respectively, as the cover is applied to the heel. After the cover applied to the heel has dried, the margins 36 of the cover inturned upon the breast 24 of the heel are trimmed flush with corresponding breast edges 34 of the heel by the use of a machine such, for example, as disclosed in Letters Patent of the United States No. ,8 4,6 granted December 1, 1931, on an application filed in the name of Charles G. Brostrom, leaving the portionsor tabs (Figs-3 and 4) of the inturned margins 36 secured within the respective recesses 26. The construction of the above-mentioned machine, which comprises a band knife 35 (Fig. 3), is fully disclosed in said Letters Patent No. 1,834,677. r r 7 After the top margin 38 of the cover 22 has i been inturned upon and secured to the attaching 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,

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'insure that the cover will be held securely in place on the rim 30 of the attaching face 32 during 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 exposing substantially the entire attaching face of the original wood heel for heel-attaching purposes. 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 application 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 finished shoe.

In order to insure that the breast of the heel of they finished shoe shall havea shape substantially the same as that of the uncovered breast of the heel, leather covers or covers of'various other materials may be advantageouslyapplied to heels in the manner above described in connection with Celluloid covers. 7 g

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

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.

2. A heel having in the lateral margins of its breast a plurality of small recesses which are spaced heightwise of the heel, intersect corresponding sides of the heel, and are of a depth not greater than the thickness of a coverto be applied to the heel. 7

3. A heel having in the lateral margins of its breast a plurality of recesses intersecting corresponding sides of the heel, anda cover which overlies the side and rear faces of the heel and has portions of its forward margins secured within said recesses and other portions of its forward edges of the heel.

1 That improvement in methods of covering heels which comprises forming in the lateral margins of the breast of a wood heel a plurality of shallow recesses which are spaced from each other and intersect corresponding sides of the heel, applying a cover to the rear and side faces of the heel and securing the forward projecting margins of the cover within the recesses and to the lateral margins of the heel breast, and trimming the portions of the cover engaging the breast of the heel flush with corresponding breast edges of the heel but leaving the portions of the cover secured within said recesses connected to the cover upon the side faces of the heel.

5. A heel having in the margin of its attaching face a plurality of shallow cover-receiving recesses which are spaced circumferentially of the attaching face and terminate at therim of said face.
