snot wrrn DETACHABLE HEEL H Elmer .Brunmark, Worcester,Mass. I rhpplicationM-a y '3', 1939', Serial Nu. 271,532 s v Q Claim; (01. 36-42 This invention relates to shoes having detach able and replaceable heels; Substantial economy may be effected by the use-of such heels, as the heel is the partiof the shoe most subject to wear most frequent i'eable: manner, as by rivets 3|extending upward through theinsole H and headed above an in and the part. which requires It is the general object of myinventionto provide improved means for securinga heel to a shoe in such a way that it may be easily attached or released without the use' of tools.

A further object is tofprovide' a construction 1 in which a portion of the attaching structure for a wood or similar heel may be formed directly in the heel itself, so that no additionalor special parts need be applied tothe -h'eel.' Animp'ortant feature of my invention also relates to' the application of a detachable heel to a shoe in'such mannerthat a substantial saving in out-sole stock may be effected. I a v My invention further relates toarrangements andcombinations of partswhich will be hereinafter described and more particularly "pointed out in the appended claim.

A preferred form of my invention is shown in the drawing, in which Fig. 1 is a side elevation of my invention; a

Fig. 8 in partial side elevation of the assembled The ou -'-"ole Ill preferably extends rearward only to the heel portion, where it provides a shoulder '30 (Figs. 1 and 4) against which the;

front edge 2! of the heel l5 abutswhen the heel is attached to the shoe. the full length of the shoe as usual, and the upper I d is in-turned and tacked or otherwise v a portion of a; woinans shoe,,partly in section and embodying The insole ll extends securedto the under side of theinsole, as indicated at 23 in Fig'. 4. I

An attaching plate30, preferably ofsomelight j -metalsuchas aluminum; issecured to the under sidecf the heel portion of the shoe in'somesuitsert or heel liner 3? underlying the slip-sole [2.

The attaching plate '30 is provided with a longitudinally extending dove-tailed projection positioned in saidrecess.

- The parts thus far described all constitute portions of the; permanent structure of the shoe.

The detachable heel i5 is commonly formed of wood or other similar material'and the cover- 1U having a longitudinal recess 36 and a stud 31 ing 16 thereof is commonly of leather or fabric: and usually corresponds in color and material to the upper l4. I Q A dove-tailedrecess 40 is formed inthe upper surface of the heel l5 and is of such dimensio ns that the recessed portion, of the heel is a close .sliding' fit over the projection 35 of the attach ing plate 39. Preferably, the upper surface of a the heel and the surfaces of therecess 40. are well' coated with shellac or other watererepellant material, so as to prevent changes'in crossisection of the recess 4B due to shrinkingor swelling of the I wood.

A locking spring]? is secured. in the bottom of the recess 4!! insorne-convenient manner, as

' by nails or pins 43; and they spring 42 is provided with anl'opening 45 to receive the stud 31 when the parts are assembled. The outer end 46 of the spring 42 overlies the front upper edge of'tthe i recess 40 and extends downward closely adja cent the front face 2| of the heel i5. g The-spring end 48 is relatively inconspicuous when. the heel is inplace but afio rds convenient means for releasing the'heel without requiring the use of tools, by simple pressure of the -finger, thereon in the direction-of the arrow a in Fig. 1.

The parts are assembled by presenting the heel at the rear of the shoe and sliding the same for-, wardalong the.dove-tailed projection 35 until the stud 31 enters the hole 45 in the spring 42 and locks-'theparts together, with the front sur-.

. face 2| of' the heel closely abutting the rear I shoulderZO of the out-,soleill; I g

- The upper edge of the detachable heel closely underlies the inturned upper J4, as shown in Fig. 8, so that merely a single separating line apstructionis readily apparent. p

The matter of stopping off the out-sole Ill at pears and no evidence of the detachable-cone.

the front edge of theheel portion is of considerable importance, as it substantially reduces the amount of expensive out-sole stock required for each shoe. Obviously, two or more heels of different styles or heights may be provided for a single shoe, by use of which the utility of the shoes may be'increased.

While I prefer the construction herein shown in which thedove-tailed recess 40 is formed di-v rectlyin the material of the heel, thereby saving the expense of making and assembling the separate parts, I do not wish to be limited to this construction, otherwise than as set forth in the claim, but what I claim is:

A shoe having an attaching plate secured thereto below its heel portion and provided with a dove-tailed projection, a heel having a dovetained recess formed directly in the material of the heel and cooperating with said projection to secure saidheel on said shoe, and locking means for said heel, said locking means comprising a spring on said heel coacting with a stud on said plate and having a release portion overlying the front edge of said recess and extending downn ward adjacent the front wall of said heel.
