DETACBABLE SHOE HEEL.

Application led February 16, 1928. Serial No. 254,767. U

heel becomes worn it can be easily and quickly removed and replaced with a new one, or if desired placed on the other shoewhere the worn portion willbeonthe inside of the shoe, consequently concealed from view 'to a great extent. A further object is to provide the detachable heel with spring male members adjacent its marginal edge and which spring male members are forced through eyes carried by the permanent portion of the shoe to positions above the eyes where they will expand into close engagement with the upper edges of the eye for rigidlyholding the detachable heel in place and taking up any slack incident to wear by their expansive force, thereby preventing lateral movement of the detachable heel during a walking operation. v

A further object is to provide a leather I layer in which the eyes are placed in accurate positions, vand which layer may be secured to the heel of the shoe with its eyes in regis-` tration with apertures in the fixed heelv portion of the shoe, for the reception ofthe expansive male members carried by the detachable heel. i

A further objectJ is to provide the male members with elongated shanks terminating in annular members imbedded in the detachable heel,and with annular members adjacent their outer.V ends andl imbedded in the inner face of the detachable heel, thereby rigidly bracing the male members and anchoring the same.

With the above and other objects in view the invention resides inthe combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the pre; cise embodiment of the invention may be made within-the scope of what is claimed without `departing from the spirit df. thel invention.`

In the drawing: j

Figure 1 is a bottom perspective view of the heel portion of a shoe showing the detachable heel removed.

Flgure 2 1s a perspective view of the detachable heel. j l

Figure 3 is a vertical longitudinal sectional-view through the heel of the shoe and the detachable heel.

Figure 4 is an enlarged vertical transverse sectional view through the fastening means and adjacent portions of the heel.

Referring to the drawing the numeral l designates the upper of a conventional form of shoe and 2 the permanent portion of the heel..

Secured to the under side of the permanent portion 2 of the heel, preferably by cement 3 is layer of leather 4, which layer of leather at spaced points around its marginal edge is provided with a plurality of metallic eyes 5 having their opposite sides imbedded in the layer of-leather 4 whereby adjacent-engaging parts will closely engage the layer of leather 4. The eyes 5 are rigid and are adapted to receive therethrough the expansive male member heads 6, which heads contract as they are forcedthrough the eyes 5 and expand into close bindingvengagement with 4the annular edges 7 of the eyes after the heads are in position as shown in Figure 4, and in the apertures 8 of the heel portion 2, and by/which' expansive action any play which may/develop is taken up, and consequently lateral movement of the detachable heel 9 is prevented during a walking operation, which would not bev the case if an expansive male member 6 were not used. Y

'I he male members 6 areprovided with elongated shanks 10, which shanks extend downwardly into the detachable heel 9 and are\pro vided with integral discs 11 and l2. The discs i 12 as well as the shank 10 yare imbedded in the heel 9, which is preferably formed from rubber, while the discs 11 are imbedded in the up-` engagement with the eyes at 7, consequently allowing lateral movement of the detachable heel during a walking operation. From the above it will be seen that a detachable heel is provided whereinexpansible fasteners are'used which will prevent lateral movement of the heel during a Walking op eration and a heel provided which may be easily and quickly removed and replaced with anew heel as the heel Wears, or if desired a worn heel may be shifted to the opposite shoe, which is particularly desirable Where the heel is Worn on one side.

Theinvention having been-set forth what is i claimed as new and useful is: 10

l. A detachable heel comprising a xed portion, a layer of material attached to said fixed portion, a plurality of eyes extending around said layer of material adjacent its marginal edge in spaced relation, annular flanges carried by said eyes and imbedded in opposite sides of the layer ofmaterial, apertures in the ixed portion of the heel in registration With the eyes, a detachable heel portion, and apluried y the detachable portion of the heel and extending through theJ eyes and having exralityb7 of spaced expansible male members carpansive engagement With the upper inner edges of the eyes.

2. A detachable heel comprising a fixed portion, a layer of material carried by said fixed portion, a plurality of eyes carried by said layer of material, a plurality of expansive male members carried by a detachable heel and extending through the eyes into chambers in the fixed portion of the heel, said expansive members having expansive engagement with the inner edges of the eyes, Shanks carried by the expansive male members, spaced discs carried by'said Shanks, said Shanks and one of their discs being entirely imbedded in the detachable heel, the other dise of the shank being imbedded in the upper side of the heel and ,engaging the eyes.

In testimony whereof II hereunto athx my signature.
