HEEL.

SPECIFICATION forming part of Letters Patent No. 784,650, dated March 14, 1905. Application filed November 12, 1902. Serial No. 130.950.

To all whom it may concern:

Be it known that we, \VILLIAM F. ZARWELL and JOSEPH B. CULLEN, citizens of the United States, and residents of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvemen ts in Heels; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates especially to heels of the class employingmetal shells; and it consists in certain peculiarities of construction and combination of parts, as will be fully set forth hereinafter in connection with the accom pan ying drawings and subsequently claimed.

In the said drawings, Figure 1 is a vertical longitudinal sectional view through a heel embodying our present invention, taken on the plane indicated by the lines 1 1 in Fig. 2. Fig. 2 is a plan view of the same, partly in section, on the plane indicated by the line 2 2 in Fig. 1. Fig. 3 is a vertical transverse seetional view of the same, taken on the plane indicated by the line 3 3 in Fig. 1. Fig. 4 is a vertical longitudinal sectional view through another form of heel embodying our said invention.

Referring by numerals to the drawings, 1 designates the rear portion of the leather sole of a shoe, and 2 a shell of metal, preferably aluminium, constituting part of our said shoeheel. The general shape or outline of the shell and the dimensions thereof are subject to variation, according to the style of heel desired, what is known as a French heel being illustrated in the first three figures of the drawings, while Fig. 4 represents what is designated as a Cuban heel, this matter of shape or outline being immaterial. The upper edge of the shell is preferably provided with sharp upwardly-extending projections 33, designed to enter the sole 1, and thereby guard against lateral displacement of the heel. The inner walls of the shell 2 are formed, adjacent to the lower end thereof, with an inwardly-extending horizontal flange 4, which serves as a stop or shoulder for the block 5, the latter being preferably of wood and of an outline corresponding to the space within the walls of the shell below said flange, the under side of said block being flush with the lower edge of the shell and receiving the pointed ends of the nails 7 7, which are driven through the leather tread-lift 6 to secure the latter to place, and the block 5 being formed with one or more vertical holes therethrough enlarged or countersunk on the lower edge to receive the screw or screws 8, which engage with the nut 9, as presently described. The said nuts 9 may be of various design or contour, according to the style of the shells 2, within which they are located; but all have upward extending preferably continuous flanges 10, terminating in outwardly-projecting horizontal upper edges 11, having vertical holes therethrough at intervals for the passage of the nails 12, which are driven through the shoesole 1 and clenched, as shown, thereby securing the nuts firmly to the soles, While the screws 8 by engagement in said nuts secure the blocks 5 to the shells 2 against the shell-flanges 4, and the nails 7 secure the tread-lifts 6 to said blocks, thus holding all the assembled parts firmly in place.

Our heels as thus constructed are inexpensive, light, and durable and readily attachable to the soles of the shoes or other footwear, such as slippers or boots, to which they may be applied, and the exterior surfaces of the shells 2may be polished, burnished, enameled, or otherwise treated, according to taste or the particular article to which they are to be attached, and said heels form a distinct commercial article independently of the shoes or other articles of footwear for which they are designed.

In the construction of hollow metal heels adapted for use with leather shoes it is of great advantage to have a narrow inner encircling flange adjacent to the lower end of the shell with a loose block of penetrable material with its edges extending under and beyond the edge of said narrow shell-flange, but protected everywhere by the metal wall of the heel, said block having a central vertical opening for the admission of a screw therethrough. It is also of advantage to have a hollow nut secured to the shoe-sole above the heel to receive the said screw, as said nut is lighter than a solid nut would be and practically as strong, and the flanges (particularlywith the conical form ofhollow nut illustrated) have a truss action and resist strain better than a solid nut would, while the described block of penetrable material, embedded, as described, is a distinct advantage in protecting the integral parts of the heel from jarring and shock. The said block not being entirely covered by metal, but only at its edge, has a certain amount of flexibility and spring action, thus always keeping the screw connection with the hollow nut taut and relieving the same from jar and shock, and the flexible tread is very readily secured to said block, thus concealing the parts above and keeping same always in place and yet (owing to the fact that there is no inflexible plate above the said block) without lessening the spring action of said block.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A heel, comprising a metal shell having pointed projections on its upper edge for engagement with a shoe-sole, and an inner horizontal flange adjacent to its lower end, extending continuously all around theinner wall of said shell and projecting inwardly only a slight distance therefrom; a flanged nut, and means for securing same permanently to said sole, independently of the shell; a verticallyperforated block located beneath the shellflange; and a screw, extending through said block and engaging with said nut, the head of said screw serving to hold said block against said shell-flange.

2. A heel, comprisinga metal shell, adapted to be held against a shoe-sole free from permanent attachment thereto, and provided with an inner narrow encircling horizontal flange adjacent to its lower end; a flanged nut permanently secured to said sole, within said shell, but free from contact with the latter; a block of penetrable material located within the lower end of said shell below said shellflange; a screw extending through said block, and in engagement with said nut; and a flexible tread-lift of an outline coincident with that of said lower end of the shell, immovabl y secured to said block.

3. A heel, comprising a metal shell with smooth inner walls, interrupted only by a narrow encircling flange adjacent to the lower end of the shell, and pointed projections extending from the upper edge of said shell; a

nut having an upwardly-extending hollow wall terminating in a horlzontal flange, and

means for immovably securing the same to a shoe-sole independently of said shell; a wooden block having a vertical central opening therethrough, and the edges of said block extending under and beyond the edge of the said narrow flange of said shell; a screw extending through the opening in said block, and in engagement with the said nut, and a flexible tread-lift held by nails to said block and concealing the lower surfaces of said shell, block and screw.

4. In a hollow metal shoe-heel, the combination with a hollow nut having screw-threads in its lower portion only, and an upwardlyextending hollow wall terminating in an outwardly projecting horizontal perforated flange; clenched nails extending through the perforations in said flange for attachment to a shoe-sole;a vertically-perforated block held in place in the lower part of said heel by a flange thereof; and a screw extending through the perforation in said block for engagement with said nut, but everywhere free from contact with the metal of said heel.

5. In a hollow metal shoeheel, the combination with a hollow conicalnut having a lower portion solid save for a vertical screwthreaded bore therethrough, and an upper annularflange with perforations ther'ethrough, for attachment to a shoe-sole; of a narrow encircling horizontal flange integral with and projecting inwardly from the lower part of the metal heel, above the base-line thereof; a vertically-perforated block of penetrable material whose upper surface is in contact with said flange and whose edge is in contact with the shoe-heel below the said flange, the lower surface of this block being flush with the baseline of said heel; a screw holding said block to said nut, but everywhere free from contact with the metal of said heel; and a leather treadlift nailed to said block and located entirely below the base-line of said heel. i

In testimony that we claim theforegoing we have hereunto set our hands, at Milwaukee, in the county of Milwaukee and State of \Viscousin, in the presence of two witnesses.
