ABRAHAM XVEIDEN'IHAL, OF CLEVELAND, OHIO.

ADJUSTABLE SHOE-HEEL.

SPECIFICATION forming part of Letters Patent No. 308,028, dated November 11, 1884.

(No model.)

To all whom it may concern:

Be it known that I, ABRAHAM WEIDEN- THAL, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Adjustable Shoe- Hecls; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in adj ustable shoe-heels, the object being to provide a heel preferably circular in cross-section, and so arranged that aportion of the heel, including the outer lower edge or principal wearingsurface, may be turned on the axis of the heel to equalize the wear.

WVith this object in view myinvention consists in certain features of construction and in combination of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view in elevation of a shoe, with the heel in section, showing my improved internal construction. Fig. 2 is an elevation in section of the mechanism for securing the heel. Fig. 3 is a view in perspective, in detail, of the mechanism shown in Fig. 2. Fig. 4. is a plan view of a circular heel-plate. Fig. 5 is aview in perspective of a portion of a circular heel with the plate shown in Fig. 4 attached.

A representsa shoe with the outer sole, A, and an insole, a, and a heel, B. The heel is wmade in two parts, b and b, that are divided on the line 00 w. The part b is secured to the bottom of the shoe, in the usual manner, and the part b is secured by the mechanism next described. The part 0 is a sleeve, and has a flange, c, with holes 0, through which screws or nails may pass to secure the flange in the part of Y the heel b. The upper end of the sleeve, at G, is made smaller, and the shoulder between the two parts of the sleeve is serrated, as shown at C The part C fits in the bore (1 of the flange D, that has a depending sleeve, (1, the lower end of which is serrated to correspond with the notches on the part 0. The upper portion of the bore in the sleeve 0 is threaded to engage the screw E,the lower end of which is hollow and threaded to receive the end of the screw 0. The lower end of the part 0 is chambered at c to receive the head of thescrew e. As shown, the screw E does not come in contact with the part D, but extends through the insole a, that is provided on the inside with the washer F,that is coun tersunk to receive the head of the screw E.

In the manufacture of boots or shoes, the

upper or flat part of the flange D abuts against the under side of the insole, and the convex under side and the sleeve d are inclosed in the sole A and the part I) of the heel. The part b of the heel is built around the part G from the serratures O downward, and when the two parts of the heel are brought together and held in position by the screw E the respective notches on the parts GandD engage each other and prevent the heel from turning. The part 0 is centered laterally in the part b of the heel, and when the screw E is backed out'or loosened far enough to disengage the said notches the lower part of the heel may be turned at pleasure, and as the heel is circular in cross-section, when the screw E is again tightened, bringing the parts in position, the heel will present a smooth, uniform surface. WVhen the parts are secured by the screw E, the head of the screw 6 protrudes some distance from the end of the screw E, and is far enough from the shoulder at the end of the recess 0 to allow the screw E to be backed out far enough to disconnect the said notchesand revolve the lower part of the heel but the head of the screw 0, engaging the said collar, acts as a stop onthe screw E and prevents the latter from being inadvertently turned out so far as to whollydiscon nect the said lower part, b, of the heel. WVhen the screw E is turned in tight, the head of the screw and the washer are flush with the insole a, and present a smooth surface on the inside of the shoe. The headof this screw is always accessible on the inside of the shoe, and the heel may'therefore be turned more or less from time to time, so that the heel is kept flat and supports the shoe properly. Almost every person wears his shoe-heels faster on the one side than on the other, so that usually about two orthree times in the life of a shoe these heels have to be repaired. The heels,when worn off on one side, are not only unsightly and uncomfortable, but they cause an undue pressure and consequent wear on the corresponding side of the sole, by means of which the sole only lasts perhaps half or two-thirds as long as if the wear were equally distributed, as would be the easewhen the heels were kept flat and even approximating a new heel. The part 7) may have one or more rows of nails around the edge, in the usual manner, or may be provided with the ring or plate G, that is provided with suitable means-as, forinstance, the ears g-i"or securing it to the bottom of the heel. A piece of leather, H, may be secured 011 the inside of the ring G and flush therewith, andmay, if preferred, be secured by the same screws that hold the plate or ring G. This ring or plate may be secured to a solid heel, and the ring from time to time may be unscrewed and turned a part way around to equalize the wear. This would not be so convenient as the device first described, but would answer for a cheap heel.

What I claim is- 1. A boot or shoe heel circular in crosssection and made in two parts, one of said parts being rigidly secured to the sole of the shoe or boot and provided with a central sleeve serrated at its lower end, and the other or movable part provided with a central sleeve serrated for engagement with the sleeve of the rigid portion of the heel, and ascrew for holding the serrated sleeves'together. 2. A boot or shoe heel circular in crosssection and made in two parts, one of said parts being rigidly secured to the sole of the boot or shoe and provided with the sleeve, as described, and the other or inovablepart provided centrally with the sleeve O,and secured to the rigid portion of the heel by a screw.

In testimony whereof I sign this specification,in the presence of two witnesses,this 20th day of August, 1884:.
