, In the drawing, wherein for the. purpose ofl illus` tration is shown a.- preferred embodiment of my intention, .the numeral 10 designates a .shea-of anywellknown or preferred construction, havingV a heel 11,. embodying; a lift12, formed of leather or the11k,and ai heel member. 13, preferablyA formed efV rubber.; .or the like. A

attaching platel 14, preferablyl formed of sheet metal, which is resilient. rlhe attaching plate is secured tothe lift 12 by screws 15, although other suitable means may Ybe employed, such as nails, cement, or the like. It is preferred that thev attaching means be arranged'upon the inner portion of the attaching plate, leaving the marl ginal edge v16, of the attachingplate free; suchY -A further object' or the. invention is .to provide Aplate has its marginal edge bent inwardly upon itself for affording a socket 18, which is generally U-shaped, with its open end arranged forwardly. This socketv 18 is also U-shaped in cross-section, with its open side disposed inwardly. This socket is adapted to receivethe marginal edge; 16 ofthe companionattaching plate.` The attaching plate 17 is mounted within a recess 19, formed in the upper face of the heel member 13, whereby the top of the socket 13- is substantially flush with the marginal flange 20, of the heel member 13, Since this flange 20 contacts closely with the lift 12 when the heel member is in place, the attach-`` ing means is completely covered from View.

As more clearly shown in Figures 3 and 7,' the lower attaching plate 17 has anchor elements or tongues 21, stamped therefrom, at spaced intervals, and' at points inwardly or"- the socket 18. These tongues are bent downwardly` and outward-'- 1y,` affording horizontal extensions 22, asshown. The` stamping of the tongues produce openings 23. .i The rubber heel member 13 .is preferably cast or molded about the attaching plate 17, and the anchor elements or tongues 21 are embedded within the material of the heel member;V and portions 2 3 of the rubber also enter and become embedded within the openings 23, thereby af.- fording a strong connection between the rubber heel member and the attaching plate. y a.

The lower attaching plate 17 is provided near its forward end with. upwardly bent lockingl tongues 2.4,.disposed at. a right angle thereto .and adapted to enter notches 25, formed in the for.

The upper attaching .plate 14'is4 providedatits central longitudinal axis` and. nearv itsxforwardV end, with a downwardly projecting spherically curved boss or lug 26, stamped therefrom, and this boss is preferably provided with a guide groove 27, extending through the central longi- 5 tudinal axis of the boss. The lower companion attaching plate is provided with a spherically curved recess 28, to receive the boss 26, and this recess is disposed at the central longitudinal axis of the attaching plate 17. The plate 17 is provided at its forward end with a guide groove 29, which leads to the recess 28, and is disposed in the central longitudinal axis thereof. When the lug 26 enters the recess 28, it serves as additional means to lock the plate 17 with theplate 14, against relative rearward longitudinal movement,

and these parts also serve to co-act with an implement, such as a nail 30, for withdrawing the tongues 24 from within the notches 25.

The operation of the device is as follows: When it is desired to place the heel member 13 in position upon the lift l2, the heel member is'brought in proximity to the rear end of the lift 12, and the socket 18 is placed upon the forward end of the marginal edge 16, and the heel 25 \.-v member 13 is then moved longitudinally forwardly 'with relation to the lift, until the mar-- ginal iiange has been entirely inserted within the socket 18, at which time the locking tongues 24 will enter the notches 2 5 and the boss 26 will enter 303 the recess 28. The heel member 13 is now'securelylocked against relative rearward movement with relation to the lift 12. To separate the heel member from the lift, an implement, such as a nail, is passed through the opening 16 in the flange 15', and this nail isl guided by the groove vSand groove 27, so that its forward end passes between the boss 26 and the recess 28, at their central longitudinal axis. The marginal edge 16, and the wall of the socket being resilient, a bendraging action occurs, Yas illustrated in Figure 6, and the locking tongues 28 are withdrawn from the notches 24, whereby the heel member 13 may now be shifted rearwardly, and separated kfrom the lift 12. The marginal iiange 16 and socket 18 are 45,..3 resilient and are so tensioned that they normally serve to hold the flange 20 of the heel in rm contact with the lift, whereby the attaching means is completely concealed.

In Figure 8, I have shown a modification of 56A the invention, wherein 12 designates the heel i" of a ladys shoe, and 13' the heel member or tip. Due to the fact that the tip is relativelyA thin, the attaching plate 14 cannot be embedded within this tip, and theattaching plate 14 and the companion lower attaching plate 17 are, therefore, reversed. The attaching plate 14 is mount-4 ed within a recess `formed in the lower end of.

the heel 13', so that the marginal edge or ila-nge 16 is coveredfrom side vision. The attaching 60 plate 14 is secured to the tip 13'.v All other parts `remain substantially identical with those shown and described in connection with the first form of the invention.

It is to be understood that the forms of my egg-invention herewith shownA and described, are toV be taken as the preferred examples of the same,l

and that various changes rinthe shape, size and arrangement of parts may be resorted to without departing from .the spirit of my invention, or 7Qg the scope of the subjoined claims.v
