' E ACHABLE HEEL.

Applicationrfiled August 18, 1921. Serial No. 493,442;

' To all whom'z't-may concern:

' Be it known that I, MAXIMILIAN J URISS, a subject of the King of Great Britain and Ire and, residing at 148 Ghuznee Street,

Wellington, New Zealand, have invented new and useful Improvements in Detachable Heels, of which the followingis a specification.

My invention relates to improvements in detachable heels or heel protectorsmade of rubber or-leather, or rubber and leather, of the type in which the protectors are removed when worn away and replaced bynew ones.

According to the present invention, I utilize preferably the metal studs which are moulded in the rubber protectors on the un derside one at the back and the other at the side. These studs engage corresponding slots in metal plates secured to the permanent heel. The slots are wide at one end and narrow at the other end to enable the stud to enter the wide part, slide freely and be adjusted in position in the narrow end of the slot, which is placed towards therim of the heel. To prevent any movement of the stud in the slot when adjusted a button mould in the rubber protector is adapted to engage a spring dome or the like in the permanent heel. The arrangement of the studs engaging. the slots and the button en: gaging the spring dome forms a triangle the apex being the stud and slot lying vertically, and the base being the other stud and slot lying horizontally with the spring button. 35 As an alternative, plates with bayonet joints may be substituted for the slots described.

eferring to the drawings, which form part of this specification, Figures .1 and 2 are views in elevation of the heel portion of a boot or shoe and the detachable heel pad or heel protector removed therefrom.

Figure 3 is a view showing the method of attaching the removable. heel or protector.

Figures 4 and 5 are side views partly in section of the heel portion of a boot or shoe and the detachable protector.

Figure 6 shows a detail of a modification.

The detachable heel. or heel protector awhich may be made of india-rubber, balata, leather, leather substitute or a combination of any or all of such materials, is provided on its underside with a series of studs or headed pins or the like secured to said heel padinany-suitable manner. The heel por- 55' tion 6 of the boot or shoe (not shown) is provided with one or more recesses or slots into which the studs or pins engage. In the example illustrated in the drawings, the heel pad ais provided with a central stud 0 located towards'th'e: rear edge of the pad and with a second stud 0? located towards the front andjonone side, whilst on the opposite side at the front is fixed a stud 6 provided with a substantially spherical head 6 The heel portion 6 is provided with recesses corresponding in position with the studs 0,61, 6, on the heel pad and each of these recesses is covered by an apertured plate f, f 79 The plate f is located centrally towards the rear of the heel and is provided with a key-hole slot g, the circular portion 9 of which is located towards the front whilst the longitudinal portion of the slot extends rearwardly towards the rear edge of the'heel. The plate 7 is also provided with a key hole slot h which lies approximate in such a position that a circle with the outer endof the slot 9 as the centre passes -l ongit-udinally through the centre thereof. The plate 7 is provided with a circular aperture k and beneath said aperture is located a spring rm ofany convenient construction which co-operates with the spherical head 6 of the stud c in the manner of a press button. The heads of the studs 0 and (Z are of such size as to pass freely through the circular portions of the key-hole slots but when said heads are slidden into the longitudinal portions of the slots the heads engage beneath the plate and the studs are thereby secured firmly in position.

The heel pad or protector is attached in the following manner.

The head of the stud c at the rear of the heel pad is first passed into the circular portion 9 of the slot 9 in the plate 7 and is then slidden rearwardly until said stud is located at the rear end'of the slot. This position is shown in Figure 3. The heel pad a is now rotated until the head of the stud d is in a position to pass through the circular portion of the key hole slot in in the plate 7 and the heel pad is then rotated about the centre of the stud 0 until the stud d is pressed to the outer end of the longitudinal portion of the slot h. The spherical head 6 of thestud e is now in a position in which, by pressure on the outer surface of the heel, the head of the stud may be pressed into the recess is, the sides of the spring m opening out to permit the head to pass and closing in again to firmly grip the head and retain the same in the locked position. The heel pad or protector is now firmly secured in position and will not be likely to become accidentally detached during wear of the boot or shoe.

The spring means employed to secure the stud e in position may be of any other convenient construction. For instance instead of employing a spring of the spring-button type, I may provide a slidable strip forked at its inner ends which passes through an aperture in the front vertical face of the heel, said sliding member being provided with a small head as indicated at n in Figures l and S which permits said member to be pulled out to release the inner forked end thereof from the head 6 of the stud e.

As shown in Figures 1 and 3, the plates f, f and f are secured to the base of the heel proper by screws 0. I may however secure the plates in any other convenient manner or if desired, I may provide a single plate 7) (Fig. 6) cut to snugly fit the base of the heel. This plate is provided wit apertures or slots 9, h, and similar in shape and position to the corresponding slots and apertures in the construction shown in Figure 1, the plate being secured to the base of the heel by screws or in any other appropriate manner.

The studs 0, (Z and 6 may be secured to the detachable heel pad in any suitable manner. As shown in Figure 5, the stud c is provided with a flange 0 on its outer'end and with a shank portion passing through a hole in the pad, the outer end of the shank portion being provided with a washer or plate 0 snugly fitting in a recess a in the outer face of the heel pad. The recess a may be filled in with cement or any other suitable material.

The studs 0, (Z and c on the pad a may be located at slightly greater distances apart than the corresponding parts of the slots 9, 7L, and aperture 72 so that when the heel is secured in position, the bending of the pad at the centre causes its edges to press tightly into contact with the edges of the heel b.

By this arrangement the button and spring dome with studs cannot be disengaged accidentally. The studs being on plates moulded in the detachable rubber protectors or on plates secured by brads to leather protectors, there are no apertures in the same to collect dirt from the roads, thereby disseminating disease. My protectors are interchangeable, thus enabling the wearer always to have level heels. This is a great advantage, as uneven wear of the heel is very unsightly; and by changing once a week the life of the heels is greatly prolonged. For the first pair of detachable protectors only, a fiat leather heel piece with the slot plates and spring dome already attached thereto ready 1 ,asaaao for nailing to the heel of the boot, may be supplied in Order to save the wearer the trouble of fixing the slot plates and spring dome separately to the permanent heel and for the purpose of aligning with the detachable protector.
