SHOE HEEL AND SOLE Arthur E. Smith, Culver City, Calif. Application January 4, 1954, Serial No. 401,919

6 Claims. (Cl. 36-245) This invention relates to shoes, and more particularly to the heel and sole construction of a shoe.

The general object of my invention is to provide an improved heel and sole construction for a shoe,-which will greatly facilitate repairing of the shoe when it becomes worn.

A more particular object is to provide an improved heel construction for a shoe, by-means of which the heel is detachably held firmly in position on the shoe and may be readily removed from the shoe when worn down and replaced by a new heel.

Another object is to provide a heel construction for a shoe of the character stated, by means of which the heel is detachably held firmly in position on the shoe by means of a single screw, whereby a worn heel may be readily removed from the shoe and replaced by a new heel.

Another object is to provide an improved heel and sole construction for a shoe, whereby the rear end of the sole may be held securely in position on the shoe without nailing said end of the sole to the upper part of the shoe.

Another object is to provide an improved construction of a shoe whereby the heel may be removed from the shoe without injury to the heel or any other part of the shoe. I

Another object is to provide an improved shoe construction including a novel metal cup to receive the heel of the shoe, for properly positioning and firmly holding the heel in place on the shoe.

Other objects and advantages will appear hereinafter as this specification progresses.

My invention is illustrated in the annexed drawing forming a part of this specification, in which:

Fig. 9 is a top plan view of the heel of my sho ef Fig. 10 is a longitudinal vertical section of the heel of my shoe taken on line 1010 of Fig. 9.

Referring more particularly to the annexed drawing, in which the same parts are designated by the same reference numerals in all of the figures, my improved shoe construction includes a three-quartersole 1, a;heel base 2, an inverted heel cup 3, a heel spacer 4, a detachable heel 5, an upper 6, and an insole 7 detachably fitted in the lower side of said upper upon the upper wallof the cup 3 and heel base 2 within the inturned flange 6' along the lower edge of said upper 6.

hired States Patent 9 The heel base 2 is formed with a forward extension 8, the under side of which extension is inclined upwardly and forwardly as indicated at 9, from a line 10 extending across said under side of said heel base 2 at the forward side of the opening in the heel base 2 for the cup 3, to the thin feathered edge 11 of said forward extension 8. The upper side 12 of a rear portion 13 of the three quarter sole 1 is inclined downwardly and rearwardly to the lower side of the sole 1 from a line 14, extending across said upper side of said sole, to the rear thin feathered edge 15 at the lower side of said sole, which inclined upper side 12 of the rear portion of the sole 1 fits against the inclined lower side 9 of the forward extension 8 of said heel base 2.

The inverted heel cup 3 is formed with a vertical wall 16 depending from an upper horizontal wall 17 through a cup-shaped opening 18 in the heel base 2 and through a corresponding opening 19 in the spacer 4. The vertical wall 16 is formed with a forward straight inner end section 20 extending transversely of the heel base 2, opposite side wall section 21 extending rearwardly from the ends, respectively, of said forward straight transverse wall section 20, and an arcuate rear end wall section 22 extending from the rear ends, respectively, of said side wall sections 21, said wall sections of the cup wall 16 extending substantially parallel to the horizontal outline of the heel 5 and the cup 3 being of smaller area than that of said heel. The outlines of the openings 18 and 19 in the heel base 2 and the spacer 4, respectively, conform to the outline of the wall 16 of the cup 3, and said wall 16 of said cup fits the walls of said openings 18 and 19 in the heel base 2 and spacer 4, respectively. The upper horizontal wall 17 of the cup 3 is of greater area than the area of the cup receptacle, as defined by the vertical cup wall 16, so that said upper horizontal wall extends forwardly beyond said vertical wall 16 in the form of an external upper cup flange 23 around the of the cup 5 is provided a screw hole 24 for the purpose hereinafter more fully described.

The heel spacer 4 is formed with an outer edge 25 which corresponds to outline of the heel 5, and said spacer is provided with the opening 19 of such shape and size as to receive the vertical wall 16 of the cup 3 and fit snugly around the outside of the lower portion of said vertical wall, which lower portion of said vertical wall depends a short distance equal to the thickness of said spacer below the heel base 2.

The detachable heel 5 is preferably formed of rubber, and a wood block 26 is vulcanized at its base in the upper part of said heel, as at 26, and extends upwardly thereheel spacer 4.

from in the outline form of the inner side of the vertical wall 16 of the cup 3 to fit snugly within said cup wall when said heel is placed against the under side of the In substantially the center of said heel block 26 is bored a screw hole 27 from the upper side of said block in alignment with said screw hole 24 in the upperwall 17 of the cup 5, toreceive the lower portion of a screw 28 which is extended downwardly through said screwhole 24 in said upper cup wall 17 of the heel cup'3 and driven into the screw bore 27 in the heel block 26 for. drawing said block into the lower end of the,

ably held securely in position on the heel base 2. A heel pad 39 is placed in the heel portion of the shoe upper .6 over the insole 7 and the countersunk head of the screw .23, and upon the inturned flange 6 of the upper 6.

The operation of my invention is as follows:

The inturned flange 6' at the lower edge of the rear and sides of the heel portion of the upper 6, is first placed against the rear and side edge portions 2' at the upper side of the heel base, and said upper flange 6 is then nailed or sewed to said rear and side edge portion 2' of said heel base. The heel cup 3 is then placed in the heel base 2, with the vertical cup-wall 16 depending downwardly from the horizontal cup-wall 17 through the cup-shaped opening 18 in said heel base 2, and with said horizontal cup-wall 17 resting against the upper side of said heel base within the inner edge of the inturned upper flange 6 at the lower edge of the heel portion of said upper. The three-quarter sole 1 is then place against the lower side of the upper 6, with said sole near its side and toe edges against the inturned flange 6 at the lower edges of the corresponding side portions and toe of the upper 6, and with upper inclined surface 12, at the rear end of said sole 1, overlapping the lower inclined surface i of the forward extension 8 of the heel base 2, which inclined surfaces 12 and 9 of the sole and the heel base, respectively, are cemented together with a rubber cement, which cement holds said overlapping ends of said sole 1 and heel base 2 securely together without nailing or sewing said overlapping ends together. The spacer d is then placed over the lower projecting end portion of the vertical wall 16 of the cup 3 against the under side of the heel base 2 and against the under side of the tapered rear end portion of the sole 1, with the outer side of said projectim vertical cup wall 16 fitted snugly in the cup opening 19 in said spacer 4, and with said rear tapered end of the sole 7 fitted tightly between the upper side of said spacer 4 and the rear end portion of the lower inclined side of the heel base extension 8. The heel 5 is then placed with its upper side against the lower side of the spacer 4 with its upstanding block 26 fitted snugly in the cup 3, within the vertical wall 16 of said cup, and the screw 28 is inserted downwardly through the screw hole 24 in the upper cup wall 17 and into the screw bore 27 in the heel block 26, whereupon said screw is turned and driven by a screw driver into said screw bore 27 until the heel S is drawn up tightly against the spacer 4 and the block 26 is drawn tightly within the cup wall 16, thus detachably holding the heel 5 securely in position against the lower side fthe spacer l and against turning, upon the heel base 2. The insole 7 is then placed in the bottom of the shoe upper 6 upon the inturned flange 6 of said upper with the heel portion of said insole extending over and covering the head of the screw 23.

When it is desired to remove a heel from the shoe, for example, when the heel is worn down, it is only necessary to lift the pad 30 from over the head of the screw 28 and then turn said screw to unthread the lower end thereof from the screw bore 27 in the heel block 5, whereupon the heel may then be withdrawn directly from the shoe.

Upon removal of a heel 5 from a shoe, said heel may be replaced by another duplicate heel 5, and secured in position on the shoe by the screw 28 in the manner here inabove described.
