UNITED STATES ELIAS TRANIDES, OF NEW YORK, N. Y. v

DETLCI-IAIBLE HEEL.

Application filed August 25, 1926. Serial No. 131,481.

This invention relates to two-piece detachable heels, an upper permanently attached part and a lower removable part.-

shoe after it has become worn, and a new one readily put in place without the necessity of going to a shoemaker.

Another object of this invention is to provide a construction by means of which a heel may be removed and replaced without the use of a hammer and nails as is customary in present practice.

Another object of this invention is to so construct the attaching means that there will be no vibration or movement between the fixed and detachable portions of the heel.

With these and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form part of this specification. It being understood that various changes in the .torm, proportion, size and minor details of construction, within the scope of the claims, may be resorted to w thout departin from the spirit or sacrificing any of the advantages of the invention.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, in wh1ch:

Figure 1 is a perspective view of a shoe showing the invention in place.

Figure 2 is a section taken as on line ww in Figure 1.

Figure 3 is a bottom view of the heel lift which is permanently secured to the shoe.

Fi re 4 is a plan view of the lower detacha le member.

Fi re 5 is a sectional view of an assembled eel.

Figure 6 is a view of a metal reenforcing plate.

Referring to the drawings, my improved detachable heel construction comprises a heel lift member 1, permanently secured to the shoe 2 and a detachable member or heel proper 3 preferably formed of relatively soft molded rubber.

Project- ions 4 and 5 shaped as dovetail tongues in the lower member fit closely in dovetail recesses 6 and 7 in the upper member, thus preventing relative angular movement or vibration between the fixed and the detachable members of thelheel.

In the lower detachable member 3 of the heel I place a curved metal plate 8 as best shown-1n Figure 4, so that it is entirely embedded in the rubber. This plate is provided at its centre with a round hole 9 which acts as a clearance hole for the passage of a screw 10 as best shown in Figure 5. The length of this late is such that it reaches to the middle of the dovetail tongues. Thus when a pressure is applied at the centre line of this plate, the pressure is transmitted equally to both dovetail tongues. In this manner the plate 8 acts as a reenforcing member to the front face 11 of the lower heel and prevents it from buckling or yieldmg under stress.

The upper half of the heel is provided with a threaded nipple 12 which is molded in the central guide rib 13. This nipple is embedded therein at an angle of approximately four degrees with the horizontal face of the heel. It is thus seen that the screw 10 1s designed to pass freely through the plate 8 and engage the threaded nipple 12 and draw both heel members together so that they shall cooperate to form a complete heel.

The screw driver 0 crating. the screw will work on an angle of approximately 4 degrees to the last and thus provide plenty clearance room for the hand of any person who attempts to remove and replace a heel of my invention.

Inasmuch as the wear on a heel when in actual use takes place on the lower face, a practically new heel may be had according to this invention by simply removin the Worn lower member and putting a new lower memter in place. According to my inven tion, this may be done by the owner of the heel himself without the necessity of goingto a shoemaker.

It will be noted that where the inclined nipple 12 enters the central guide .rib 13, material has been added which forms a semicircular projection 14. To clear this projection there has been provided a cavity 15 in the middle of the lower heel member, between the projecting tongues 4 and 5.

While my invention may be used in conjunction with any make of.a shoe having a worn heel, it is my intention to appl these two-piece heels to new shoes specia y designed for their use. This two-piece heel will then be a permanent part of the special shoes, the upper member remaining permanently attac ed thereon, and havinga life as long as the life of the shoe, while the lower resilient member will be Worn out and replaced a number of times during the life of the shoe.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A two-piece heel, comprising an upper heel member having longitudinal grooves and a central rib, a lower heel member having longitudinal tongues to resiliently fit the 15 grooves aforementioned, a front face memer fitting'against the central rib and a longitudinal screw upwardly inclined through the front face member into the body of the central rib.

2. A two-piece heel, comprising an upper heel member having longitudinal grooves and a central rib, a lower heel member having longitudinal tongues to resiliently fit the grooves aforementioned, a front-face member fitting against the central rib, a reinforcing member within the front face, and

a longitudinal screw ,upwardly inclined.

through the front face and through the rein forcing member into the body of the central rib.
