Application January 8, 1934, Serial No. 705,711
8 Claims. (Cl. 36-32) This invention has for its object to provide a novel construction of sole andheel particularly for application by a cementing process to the upper of a. boot or shoe. v
The object of the invention is further to provlde a construction in which the entire sole and heel is molded from a composition such as a rubber compound and in which the heel section is strengthened and lightened by having embedded therein a vertical,-hollow, rigid, tubular shell. a
The object of theinvention is further to provide in such a construction a stifiening shank embedded in the composition and interlocked with the tubular shell, of the heel.
The object of the invention is further to provide a novel construction of heel lift cooperating with the tubular shell in the heel section.
The object of the invention is further to pro vide a construction of separate heel embodying the main features 'of the invention.
The object of the invention'is further to pro-- vide a construction of the integral sole and heel which shall present a neat, pleasing and finished appearance throughout its edge and which shall be of a character to facilitate cementitious adherence to the boot or shoe upper.
These and other objects andfeatures of the invention will appear more fully from the accompanying description and drawing and willbe particularly-pointed out in the claims.
Thecompletesole and heel construction of this V invention is particularly designed for application to a boot or shoe upper in that type of boot and shoe construction in which the entire sole is applied to the upper by being cemented thereto under pressure. A heel construction embodying the invention if used alone may also be applied in any desirablemanner.
The drawing represents preferred forms of the invention in whichthe composition from which the article is molded is a rubber composition of any suitable character molded into shape by any- Fig. 2 is a bottom plan view of the construction shown in Fig. 1 with the heel lift removed and with the central portion of the sole at the bottom partially broken away.
Fig. 3 is a view in cross section on the line 33 of Fig. 2.
Fig. 4 is a view in cross section on the line 44 of Fig. 2.
Fig. 5 is a view of a separate heel in vertical 5 cross section.
Fig. 6 is a view in cross section on the line 66 of Fig. 5.
Fig. 7 is a view in cross section on the line 1-1 of Fig. 5'.
10 Fig. 8 is a side elevation of theheel lift and lower portion of the heel section separated.
v Fig. 9 is an enlarged detail view similar to a portion of Fig. 4.
The general shape and proportions of the. com- 15 plete shoe and heel construction depend as usual upon the character of shoe to which it is to be applied and for purposes of illustration are here shown as of a type suitable for a fairly high heeled ladys shoe. The entire article, that is, 20 the sole section and the heel section, but without the heel lift, is molded as an integral unit from a suitable composition such as a rubber compound. A hollow, rigid, tubular shell I, preferably made of metal such as aluminum or light 25 steel or which may be made of other stiff and rigid material such, for example, as a vulcanized fibre board, is provided of a size and shape depending upon the size and shapeof the heel. This shell in cross section should be of sufiicient 30 size to be slightly less than the minimum cross section of the completed heel section so as to leave entirely surrounding it a solid wall of the composition and it should be of suflicient length so as to extend slightly below the bottom of the 35 heel section before the lift is applied so as to extend nearly to the top surface of the heel section. Preferably also a shank stifiener 2 is pro-- 'vided and arranged to have a locking engagement with the upper end of the shell. For'this pur- 40 posevthe shank stiffener is illustrated as a fiat strip of steel bent to conform with a desired shape of the shank of the sole. At its rear end this steel strip, which is of less width than the interior of the shell, extends through slots in the 45 front and rear walls of the shell adjacent its upper end and slightly rearward thereof and at its forward end is preferably enwrapped by a strip of fabric 3 extending slightly into the tread of the sole. A layer of rubberized fabric such as rubberize sheeting 4 extends over the entire top surface of the sole and heel.
The shell, shank, composition, and layer of rubberized fabric are assembled in the mold and 55 molded together under pressure by usual methods employed in molding to bring the article to the required form such as illustrated. The result is that the shell andshank are embedded in the composition with the composition protruding slightly into the upper end of the shell down between the stiffening shank and the walls of the shell, and the layer of rubberized fabric 4 is adherently and inseparably secured to the top surface throughout. In the molding operation the entire periphery is depressed at the top surface to form a depressed flange 5 and the depressed section is formed with a smooth surface throughout while the entire remaining undepressed portion of the top surface is roughened as indicated at 6 in the enlarged detail in Fig. 9.
The lower end of the heel section is closed by a heel lift preferably of the construction illustrated and preferably molded from the same composition employed in the molding of the integral heel and sole sections. In the construction illustrated, the shell I of the heel section is left protruding slightly below the composition 1 of the heel section as shown in Fig. 8. The body of the heel lift is molded to form a base 8 having a cross section similar to the lower end of the body of the heel section and a plug 9 having a cross sectioncorresponding to the interior cross section of the lower end of the shell I. A rigid plate l0 upwardly flanged at H throughout its periphery is embedded in the base 8 of the heel lift and. the flanged portion is shaped tightly to fit over the exterior of the lower end of the shell I. This plate In, as shown in Fig. '7, is provided with a plurality of apertures 12 to permit the composition to pass through it. It will thus be seen that when the heel lift is forced into place, occupying. the position shown in Fig. 1, it fits snugly the lower end of the heel section. Preferably cement is applied to the heel lift before being forced into position with the plug 9 protruding into the lower end of the shell.
The heel section may be formed independently for use as an independent heel in shoe manufacture and such a construction is illustrated in Figs. 5 and 6. The only difference in this case over the construction already described is that the topsurface of the heel is shaped to the desired conformation and the metal strip passing through the slots in the front and rear walls of the shell adjacent its upper end is preferably a strip of wire netting or reticulated metal 'such as shown at l3. In the form illustrated, this strip after being passed through the slots in the front andrear walls of the shell is bent over the upper ends of the shell parallel with itself, as shown in Fig. 5, so that it is twice embedded in the composition.
The construction of the heel lift is the same as already described.
The smooth depressed flange 5 at the periphery of the complete sole and heel construction presents a finished sole edge giving a neat and pleasing appearance to the completed boot or shoe when the integral sole and heel is cemented thereto and the roughened surface .6 facilitates the cementitious adherence of the sole and heel construction to the upper. The heel section of the integral sole and heel construction or the heel when used independently may further be secured by driving staples or other fastening devices from the interior of the shell through the composition and around or through the metal strip at the top into the shoe upper.
The invention thus presents a construction which when applied to the shoe gives a. neat and pleasing appearance causing it to resemble a. welted shoe by reason of the smooth depressed flange 5. The composition as a result of the molding operation presents a neat, smooth exte- 5 rior surface. The heel portion has great strength by reason of the embedded shell and at the same time the construction is light in weight owing to the large amount of empty space within the shell.
With the shank construction preferably employed, 10 I the stiffening shank is held rigidly in the desired position and the entire construction is strengthened by the interlocking of the rear end of the stiffening shank with the shell embeded in the heel. 15
Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is:
1. A sole and heel comprising integral molded composition sole and heel sections, a vertical, hol- 20 low, rigid, tubular shell embedded in the heel section with the composition covering and protruding slightly into the upper end of the shell, and a heel lift covering the lower end of the shell and heel section. 25
