LEON BUCKNER, OF NEW YORK, N. Y.

HEEL.

Application filed September 27, 1921. Serial No. 503,540.

To all'tvhom it may concern:

Be it known that I, LEON BUGKNER, a citizen of the United States, residing at New York city, in the county of New York, State of New York, have invented certain new and useful Improvements in 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 heels which may be put on and taken off by the user and, therefore, which may be renewed by the user whenever it becomes necessary, and which may be shifted from one foot to the other when the heel becomes worn on one side. While preferably made of rubber, any desired material may be used.

The invention may be embodied in a one piece heel, or it may be embodied in a twopart heel. In either case, the heel is provided with a number of sockets, which are adapted to engage over a fastening element provided with a ball-head. Thefastening element in question is simply a nail, the head of which is considerably enlarged for coopcrating with the socket in the heel, and which is provided with a sharpened portion so that it may be driven into the shoe. This nail is provided with a shoulder adapted to bear against the shoe for limiting the inward travel of the nail, whereby all of the nails will be driven in the same distance.

In another aspect, the ball may be made in two parts, which, by a suitable ke may be spread apart after the ball-hea is in place in the socket in the heel, for more securely engaging the ball-head with the socket. In order to more securely hold the ball elements in their respective sockets, a

wire may be embedded in the heel with elastic looped portions arranged adjacent the sockets so that the ball elements will snap through these loops and be held in place in the respective sockets, thus forming a .ball and socket detachable fastener.

The invention is also applicable to two part heels. In ordinary usage, a heel wears away on the outside while the inner part of the heel is subjected to very little wear. In accordance with this invention, the worn outer part of the heel is taken oif and a new one put in place, thus giving practically a new heel with only the necessity of renewmg the-outer art of the heel. Also, the heels may be s ifted from one shoe to the other to equalize wear.

In the case of a two part heel, the inner heel may be nailed to the shoe in the ordinary way and the outer part may be made detachable by the ball and socket arrangement that has been described; or, in another aspect, both the inner and outer heels may be made detachable by the ball and socket fastening means.

The looped wire fastening means that has been described may also be made convex toward the ground, so that when the fastening nails engage with the wire, the will bend the convexly bent wire so that it will tend to press the heel into close contact with the shoe.

The several heels involved in this invention are preferably made of rubber, but, of course, any desired material can be used.

The disclosure of this invention is rather closely related to my co-pending application, Serial No. 491,922, filed August 13, 1921, and to my second co-pending application, Serial No. 501,415, filed September 17, 1921.

Preferred embodiments of the invention are illustrated in the accompanyingdrawings, wherein similar reference characters are used to designate similar parts.

Figs. 13 and 14 are side and end views of a locking pin used with the fastener of Figs. 11 i 12.

Referring first to Fig. 1, the inner heel 5 is nailed to the shoe with the ordinary t pe of nail 6 associated with the washers 7. e

outer heel 8 is more or less U-shaped and is fastened to the shoe by a ball-headed fastening element 12. The two heels are cooperatively beveled as indicated at 11, the direction of the bevel being such that the inner heel helps to hold on the outer heel, as it is evident that the outer heel is more liable to engage with obstacles that would tend to pull it off than is, the case with the inner heel. The two heels may also be chamfered as indicated at 9, so that in case one heel is a little thicker than the other, an objectionable projecting edge will not be formed.

The outer heel 8 is provided with a recess 10 extending therethrough which is enlarged as indicated at 12 to form a socket. This is shown in more detail in Fig. 7. The fastening element for this heel comprises a ballheaded element 13 provided with a nail portion 1 1 and a limiting shoulder 15, as shown more particularly in Fig. 3. The ball 13 cooperates with the socket 12 to form an ordinary ball and socket joint. The fastening element may be first driven into the shoe and the heel then snapped in place so that the several ball-heads engage in the respective sockets 12. The nails 14 are driven into the shoe until the limiting shoulder 15 contacts against the shoe, so that they all will project from the shoe the same distance. Instead of first driving in the ballheaded elements and then applying the outer heel, the outer heel may be put in place around the inner heel and then the ballheaded nails may be inserted in the recesses 10 and driven into the shoe, thereby automatically positioning the several ball-headed elements in the right place for engaging with the several sockets. The elasticity of the rubber is such as to allow the shoulder 15 and the ball 13 to pass through the recesses 10 to their proper position.

The modification shown in Figs. 4, 5 and 6 is directed to means for more securely fastening the ball elements in their respective sockets, and also for holding the heel portions more tightly against the shoe. The first of these objects is attained by embedding in each .heel portion 5 and 8 a wire 20 which is provided with elastic loop portions 21 adjacent the shoe side of the sockets 12, bordering the sides of the sockets, and spaced apart a distance somewhat less than the diameter of one of the ball-heads 13, so that the loop has to spring apart to let the ball element pass, after which it snaps together into the neck below the ball-headed element for holding it more securely in place in the recess.

The described wire 20 may be substantially flat, that is, may be made all in one plane, or it may be convex toward the ground as is shown in Figs. 5 and 6, so that when the fastenin elements are driven in place they tend to atten out the convex part of the wire, so that it will press the heel portions into tighter engagement with the shoe. These heel portions just described may be beveled as those shown in Fig. 1 are beveled.

Fig. 8 shows a one piece heel 25 which is provided with a plurality of sockets 12 for cooperating with the ball-headed nails 13. A wire 26 provided with loops 27 adjacent the respective sockets 12, act in the same way as the wire portions 20 and 21 do in Fig. 4. In Fig. 9 the wire 26 is substantially fiat. In the modification in Fig. 10 it is made convex toward the ground as indicated at 26', for pressing the heel toward the shoe when the nails 13 are in place.

The modified fastening device shown in the remaining figures comprises a ballheaded fastening element 28 having the head formed in two connected parts, shown at 29, of elastic metal, which normally lie together, but which may be forced apart by a pin such as shown in Figs. 13 and 14. Recesses 29 are cut into parts 29, as indicated. This pin, indicated at 30, is provided with a slotted head 31 and two laterally extending lugs 32. The fastening device or nail 28 is first driven into the shoe as shown in the upper part of Fig. 11. The heel, which may be a one piece heel or an outer or inner heel, provided with the usual socket 12, is forced into place until the ball portion is in the socket 12. The locking pin 30 is then forced in between the two halves 29 of the ball head of the nail 28, with the lugs 32 in the same plane as the plane dividing the two halves of the ball head. By means of a screw-driver the pin 30 is then turned about 90, the lugs 32 forcing the two halves 29 apart into tight engagement with the socket 12, until the lugs snap into the recess 29' to thereby lock the spread head portion in the recess 12. Evidently the fastening device may be unlocked by turning the looking pin 30 back through 90 and removing it, thereby allowing the two halves 29 of the head of the fastening device to spring together so that the heel may be removed. A latching wire as shown in Fig. 8 could be used with the fastener if desired.

While the invention has been described in considerable detail, it should, of course, be understood that the inventive ideas involved may be carried out in many other ways, as expressed within the scope of the following claims.

I claim:

1. A heel provided with a recess extending therethrough, part of the recess being enlarged to form a socket, in combination with a ball-headed nail, provided with a shoulder below the head, the nail being driven in through the recess in the heel into the shoe so that the shoulder contacts against the shoe and the head of the nail engages in the socket, the recess being shaped so that the heel can be removed without injury thereto by pulling it away from the shoe, the nail remaining in the shoe.

2. A heel provided with a recess having an enlarged portion extending therethrough, in combination with an expansible headed fastening, said fastening being adapted to be inserted through the recess in the heel into the shoe until the head of the fastening engages the enlarged portion of the recess,

means for spreading the head of the nail the socket.

4. In a heel, the combination with a split ball-headed fastening, a socket in the heel for receiving said fastening, and means for spreading the head of said fastening in the socket.

In testimony whereof' 'I afiix my signature.

LEON BUOKNER.
