DETACHABLiE RUBBER HEEL.

Specification of `Letters Patent. Patented Jan. 25 1921.

Application mea August 19, 1919. serial No. 318,479.

To all whom t may concern.'

Be it known that I, ANDREW G. BUoHMAN, a citizen of the United States, residing at Kenosha, in the county o-f Kenosha and State of Wisconsin, have invented certain new and useful Improvements in Detachable Rubber Heels, of which the following is a specification.

This invention relates in general to shoes and more particularly to the heels thereof, having for its principal object the production of a detachable heel.

Another object ofthis invention is the production of a detachable heel preferably of the rubber type, although of course, it may be-of leather, whereby when it is necessary tov repair the heel of a shoe it may be done by a layman at only the nominal cost of the heel. n, 1*

Another object of this invention is the production of a detachable rubber heel having a plurality of cups therein havingefficient means for holding the same in position while heads arecarried upon the permanent heel portion of the shoe for being received within the cup to detachably hold the-heel in,

position, thus providing a ysuper-resilient, durable andr economical heel.

One practical form of construction andv Figure 1 is a sectionalview throughv the detachable heeland shoe.

Fig. 2 is a bottom heel of the shoe.

Fig. 3 is a top plan view of the detachable rubber heel with the cups in position.

Fig. 4 is a longitudinal section through'the plan view of the fixed detachable heel per se taken on thel line 4 4 of F ig. 3.

Fig. 5 is a transverse sectlon of the detachable heel taken on the line 5-5 of Fig. 3. Fig. 6 is an enlarged fragmentary detail' sectional view through a portion of the detachable shoe heel when ,securediup'on they fixed heel of the shoe showing speclfically the construction of the cup and the head and their manner of engagement.

In a preferred embodiment of the present invention, about to be specifically described,

for the purpose of illustration, a portion of a shoe is illustrated at 10 having the usual sole 1'1 and fixedheel 12. Any suitablefform of shoe or any size may be employed in con- ,in Figs. 3, 4 and 6.

y tachably supported.

The detachable rubber heel is shown at 13 and is of substantially conventional shape and form as illustrated in Figs. 3, 4 and 5. The heel -is provided with a dished upper surface 14 so that when the heel is fixed upon the fixed heel the forward end thereof will bind tightly in engagement with the fixed heel `to forma tight closure and thus preventing entrance of moisturebetween the fixedand detachable heel and also acting as a tensioning device for holding the connections between the detachable heel and the fixed heel 'from becoming loose under any circumstances. f

When the rubber heel 14 is being formed, a plurality of cups are molded therein, the construction of the cu s being clearly shown v ach cup comprises a base 15 of considerable size and a wall 16 rises from one surface of the base 15 remote from the ,periphery of the base. Accordingly, when theheel is being formed and the cup is. molded therein a part of the rubber will overlie the upper surface of the base as shown clearly in Fig. 6 to permanently fix the cup withln the heel. The wall 16 is provided with an annularbead 17 at its upper 18. vThe heel 13 is provided with a soc et 19 extending thereinto from yits upper surface, thus .allowing free access to the cups carried thereby .as illustrated in Fig. 3.

edge, the bead being provided with'a con- 'caved 'inner surface for receivingav lock" rin It will be noted however, that'the poftion of the rubberheel 13 below the base of each c up .is even and solid, thus increasin the resiliency of the rubber heel as well as its time of -usefulness and also prevents anyk vmarring of the fioor'over .which the shoe may pass whileit will further be noted that no portions are provided in which mud or refuse may collect at times and be discharged on polished surfaces o r elsewhere.

A plurality of heads are fixed upon the fixed of the head 2O has a concavedouter surface as shown at 23, thus providing a bearing portion upon which the lockin engageas shown in Fig. 6.. The head 20 is flanged as shown at 24 whereby the head may evenly and firmly bear upon thelower surface of the fixed heel 12.

As many heads may be fixed upon the fixed heel 12 and as'many cups may be formed in the detachable heel 13 as may be desired. It being preferable of course to include the same points where the greatest strain takes place. All that is necessary to attach theheel .14 is to place the same below the fixed heel 12 so that the heads will be in registrv with the cups.` Pressure then being applied to the'shoe will cause the heads to pass into the cups at which time the locking rings 18 and walls 16 may yield slightly until the enlarged lower ends of the heads are passed below the rings 18 and then the cups will again assume their normal positions so that the locking rings will Ilock the cups in engagement with the heads and thus rmly fix the detachable heel upon the fixed heel. f

If it is desired to replace the detachable heel for instance after the same has been worn out or in the event there is a tendency of the user to run over his heels upon one side or the other, then an implement may be inserted between the detachable heel and the fixed heel and the detachable heel may metal structures`will vbe very small and asY the cups are molded in the rubber heels all the person using the same has to do is to r'secure the heads upon the fixed heel of the shoe and then by lacin the rubber heels below the' fixed hee s of t eshoe and pressing upon the rubber heels properly will hold the rubber heels in position very easily. Ac-

f cordingly, a layman may accomplish this resultwithout any difficulty thus minimizingthe cost of repairing his heels to a very nominal expense.

As above pointed out, owing to the fact that the rubber heels are preferably dished when the heads engage the cups the outer f portions of the rubber heels will be more firmly held upon the lower surfaces of the fixed heel, thus providing a tight closure `for lpreventing the entrance of moisture or fr ring 18 may any refuse between the two heels, while the lower surface of the detachable heel will increase the resiliency of the same and will also prevent the same from marking polished surfaces as is so oftenthe case with the ordinary rubber heels now in use and also the heels are often secured so as to bring about injury to said surfaces.

` It will be therefore seen that a very simple and efficient detachable rubber heel has been provided wherein the cups are so arranged that when the heels are being molded or formed the c s will be pressed therein so as to be permanently retained after the rubber heel has been produced. This is`accomplished by the manner in which the portions of the .base of each cup projects beyond the outer surfaces of the wall thereof. The wall and locking ring present a yielding or resilient locking engagement for engagement with the heads whichare permanently mounted upon the fixed heel of the shoe. It will further be understood that although the heel 13 is designated as a rubber heel without departing from the spirit of the invention it might bea composite leather heel wherein the cups are embedded as the vsections of the lever are connected together so that the layman could just as well repair his first heels with leather heels, just as above stated, the noveltyin the case includes more specifically the manner of connecting the detachable heel to the fixed heel than to any other feature of construction.

Although the invention as described has been indicated as a half heel it is obviousv without departing from the spirit of the invention, the heads may be permanently fixed upon'the sole of the shoe at'the heel thereof' to connect a full heel in position just as readily as a half heel the construction and operation of the device being under all conditions the same.

The foregoing description and the draw! ings have reference to what may be considered the preferred or approved form 0f my /cure by Letters Patent is In combination with a shoe including a fixed heel,`heads afiixed upon said fixed heel, a detachable heel having sockets therein, cups positioned within said sockets, each cup comprising a base having a wall extendingfrom one surface remote from the periphery thereof, the wall having a bead adjacent its upper edge, the bead being provided with a concaved inner surface, for.
