Application filed October 23, 191.3. Serial No. 796,906.

T o all whom it may concern -Be it known that I, `WILLIAM M. FRiTsoHE, a citizen of the United States, residing at Mangum, in the county of Greer and State lof Oklahoma, have invented certain new and useful Improvements in Detachable Heels; 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 appertains to make and use the same.

This invention relates to detachable rub ber heels, and one of the principal objects thereof, is to provide means for securely holding a heel' in detachable position on a shoe, at the same time allowing of easy detachment of the heel, without danger however of the heel becoming accidentally removed while in use.

Another object of the invention is the provision of a detachable heel which will be simple, durable, efficient in operation, and inexpensive to manufacture.

With these and other objects in view the invention consists in theconstruction, combination, and arrangement of parts hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which like reference characters indicate like parts throughout the several views, and in which,

Figure 1, represents a vertical longitudinal sectional view through the heel of a shoe, showing the attachable heel in place thereon. Fig. 2, represents a bottom plan view of a heel of a shoe, showing one of the attaching plates secured thereon, the removable heel being removed. Fig, 3, represents a plan viewv of the removable' heel showing the other attaching plate in position thereon. Fig. 4:, represents a plan view of the detachable heel showing a modification of one of the attaching plates secured thereon, and F ig. 5, represents a transverse sectional view of a shoe witha modified form of detachable heel secured thereon.

Referring more particularly to the drawing, numeral 5, indicates the leather shoe heel and .6,l indicates a detachable heel, which is preferably formed of rubber, but which may be formed ot' other material without departing Vfrom the spirit -of the invention. i i

A shoe plate 7, which is substantially of the same shape as the shoe heel 5, but which and over which the is less in area than said shoe heel, is secured to the shoe by means of Vnails 8, and is provided withV spaced lugs or teeth 9;., slightly bent toward the shoe heel, and which are adapted to bite into the leather of the heel when the plate is nailed in place. Secured 1n spaced relation around the edges of plate 7, are a plurality of ball members 10, of ball and socket clasps.

A heel plate 11, provided with downwardly extending edges 12, is molded into the rubber heel 6, the edges 12, being cut out or recessed at intervals as'at 13, whereby teeth or prongs 14;, are formed, between rubber is molded, whereby the heel plate is secured in place on the heel. That portion of the heel G, inclosed within the downturned edges 12, is cut away to form a recess 15, into which the ball members 10, project, when the heel is secured in place, said heel plate 11, being -provided with a plurality of eyes 16,

through which the balls 10, are adapted to be forced in securing the heel in place.

The shoe plate 7, illustrated in Fig. 5, is provided with spaced round buttons 10, which are formed on the outer ends of Shanks 17, secured to plate 7', a button being situated near the ropposite edges of the plate at the forward portion thereof, and said plate is provided at its rear end with a turn button 18, secured by means of a shank 19, to the plate, said plate being formed similarly to plate 7. The heel plate 11, is formed similarly to plate 11, except that it is provided `with key hole slots 20, extending in the same direction, and in spaced relation, and is also provided with a rectangular slot 21, in which when securing the rubber heel to the shoe, the turn button 18, is adapted to be inserted, said heel being'then turned until buttons 10, drop through the enlarged portions 22, of the lkey hole slots, said plate where the slots occur being stamped or bent downwardly as at 23, so that when the buttons 10, are inserted through the enlarged portions 22 of the 'key hole slots, the Shanks 17, will ride down the sloping portion of the heel plate until they reach the ends of the smaller portions 24, of the key hole slots, the plate at this portionbeing slightly converted in which concavities the buttons 10', are adapted to rest as illustrated in Figc. When the heel is thusb secured in place, the turn button 18,

along the key hole slots and it will thus be impossible to accidentally disengage the rubber heel fromj the shoe. 'i In both the` modifications, the heel plate is molded into the heel and said heel is recessed orcut away within the downturned edges of the heel plate., into whichv recess the clamping means of the shoe plate extend. In detachlng the heel shown in Fig. 5, all that it is necessary to do is to turn the same until the enlarged portions 22, of the key hole slotsv register with buttons 10', whereupon the fore part of the heel may be forced slightly away from the shoe, thus disengaging the buttons through the enlarged portions of the slots, and by continuing the turn, the turn button 18, may be brought into registration with slot 21, whereupon the heel may be drawn away from the shoe.

In removing the heel illustrated in Fig. 1, a knife blade or other Hat instrument must be inserted between the heel and shoe and between the outer edges of plates 7 and 11, whereby the plates may be pried apart, thus separating the heel, any ordinary pull or forcing without the use of an instrument not being available to remove the heel from the shoe, and consequently there will be no danger of the heel becoming accidentally loosened or removed from the shoe.

It is evident that by this construction when a heel gets `worn away, a new heel may be attached in its place, and without the reqirement of skilled labor, and in a very short time, and in this connection should the heels of a pair of shoes be run over or worn down on one side more than on the other, the heels may be interchanged from one shoe to the other for obvious reasons.

Although I have described the preferred embodiment of my invention, I may desire to make such' changes in the construction, combination and arrangement of parts as do not depart from the spirit ofsthe invention and the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters-Patent is: l

1. Means for securing a detachable lift to a shoe heel comprising a heel plate arranged to be secured toa heel, a plate arranged to be embedded in the detachable lift, shanks secured upon said heel `plate, and ball heads formed upon the ends of said shanks, said lift plate having key. holel slots formed therein, and its portions at thelsides of said slots deflected laterally and inclined longif tudinally, said lift plate also having a lconcavity formed at the lower ends `otqeach of said slots and projecting in oppositedirection to the side edges of said slots, whereby to provide for the downward travel of said shanks through said slots and the subse'- quent seating of said ball heads in said concavities for securing said lift to said shoe heel. Y 2. In combination with a shoe having a heel, a plate secured to said shoe heel, a detachable heel member for said shoe heel, a` plate embedded in said detachable heel member, shanks secured upon said shoe heel plate, and ball heads formed upon the ends 'lasA of said shanks, said detachable heel member plate having key hole slots formed therein, and its portions at the sides of said slots deflected laterally and inclined longitudinally, said plate also having a concavity formed at the lower ends of each of said slots and projecting in opposite direction to the side edges ot' said slots, whereby vto provide for the downward travel of said shanks through said slots and the subsequent seating of said ball heads in aid concavities for securing said detachable heel member to said shoe heel.'

In testimony whereof I have signed my name to this speciication in the presence of two subscribing witnesses.
