' DETACHABLE HEEL FilewFebQl, 1947 2 sheets-sheet 2 from the recess 28, and the bottom of the recess 29 is spaced upwardly :from the bottom ofthe recess 28.

nular cover plate 45, having depending flanges 48 is adapted to engage in the recess 28 for closing it when the heel is locked. The cover plate 45 is provided with a rectangular opening 41 on one edge thereof, through which the lever 38 will be engaged when in the locked position.

In the use and operation of this locking device, when the heel and shank stiiener are removed from the shoe, the iirst step in assembly is to insert the shank stiiener I2 into the passage I'I between the insole and outsole,`and slide the heel down to its approximate position on the shoe. The bolt 24 may be rotated prior to the first step so that the head 34 extends forwardly An opening is formed in the bottom of the recess 28 and is substantially annular, through gj which the bolt 24 is adapted to extend. The

bottom of the recess 28 is adapted to overlie and abut the plate I9. The bolt 24 is formed at its upper end with a rectangular shankBI. The shank 3| is formed with a groove 32 on one side thereof, and a head as 34 on the extreme'upper end of the shank is adapted to extend'over the groove 32 to provide an enlarged headon the bolt 24. The lower side of the head 34 and the groove 32 form a hook 35 on the upper end of the -bolt 24.' n Y The bottom of the recess 23 is formed with a rectangular opening 36 on loneside of the opening 30, and communicating therewith, whereby the head of the bolt may be extended through the opening 3l formed by the openings38 and36 in one rotated position of the bolt 24. In other positions of the bolt 24, the head 34 will not'be in proper alignment with the opening 3l and may not be inserted through the opening for attaching or removing the heel. e

A lever 38 is engaged with the hook 35 for locking the'heel to the shoe. lThe lever 88 is formed with an elongated arm 39 at one end, and a pair of bifurcated arms 40 at the other end. A connecting bar 4I is fixed between the arms 4D near the lower end thereof. The arms 48 at their extreme end are bent as at 42', to provide a cam surface below the connecting bar 4I. The arms 40 are spaced outwardly of the opening 3l sothat pivotal movement of the lever 38 will effect locking of the heel to the shoe, or in another position will provide for the removal of thelever 38.

`The connecting bar 4I is adapted to beengaged in the groove 32 below the head 34 in the hook 35. In one pivoted position of the lever, as shown in Figure r4, the connecting bar 4I is rmly engaged in the hook 35 'and the extreme ends of the arms 4 2 engage the upper surface of the plate 2l within the recess 28 for lockingthe heel to the shoe.V o V In the reversed or opposite position 0f the lever 38, the cam 42 4will be moved tothe oppositely pivoted position, whereupon the bolt 24 and the lever 38 will be raised free from engagement with the plate 2l` to. be removed from the hook 35. The bolt '24 maybe rotated by the lever 38 in either position of the lever when the connecting bar 4I is engaged inthe hook 35. The arm 39 of the lever 38 is bent downwardly tolie flush with the plate 2l in the lockedposition. In the properlylocked position of the Alever 38 and bolt 24, the arm 39will lie .in the `recess-29 of the` plate 2`I.v i l f To provide for the added comfortl ofthe shoe, a cover 'of flexible material as leather 44, is adapted to be placed over 4the plate 21. An anof the heel, whereby the head of the bolt may be slidably engaged through the opening 31 in the plate 2l.V The lever 38 is then disposed with the connecting bar 4I engaging in the hook 35. The lever 38 is then pivoted about the connecting bar 4I for tensioning the bolt 24. The lever 38 may then be rotated aboutthe axis ofnthe bolt 24, effecting rotation of the bolt I l'ie` arm 38 will Ythenbelengaged in the opening 29 and the heel and shank stilener locked in place. The cover plate 45 may then be inserted in place and the cover 44 placed over the assembly.

I do not mean to confine myself-to the exact details of Vconstruction herein disclosed, but .claim all variations vfalling within the purview `of the appended claims.

, WhatIclaim is:

l. A shoe comprisingfan upper, an-insole, an outsole, a heel, a plate in the rear of saidlshoe above said insole.. saidplate formed with a recess centrally' thereof, saidrecess extendingy downwardly through'said insole, a platepn saidheel between said heel and said insole, arboltcarried bysaid heel vextending upwardly throughsaid latter plate and into said recess, a squared shank on said bolt insaid recess, said shank formed with a groove on `one side below the upper end thereof forming a hook, a bifurcated 1ever a cross bar between the arms of said lever engageable in said hook, said lever extending beyond said cross bar forming `a cam on said lever wherebyv pivotal movement of said lever in one direction about said cross bar engaged in said hook will effect locking of said heel on saidshoe, .androcking of said lever'in the opposite direction will permit removal of said lever from said hook and removal of said heel from vsaid shoe. f i

I 2.o'A shoe as set forth in rclaim 1, including a shank stilener on said latter plate extending forwardly from said heel, engageable between said insole and saidoutsole. 3. In a shoe having an upper, a'sole,'a n'd a removable heel, means securing `said heel on said shoe including a bolt on said heel'extending upwardly therefrom, a notched` shank on the upper end'of said bolt forming a hook, '.a'n apertured plate in said shoe about said shank, a bifurcated lever, a cross bar between thearms of saidv lever intermediate the length thereof engageable'in saidr hook, said armsengageable with' said plate in one position of said lever for lock-l ing said heel-onsaid shoe and removable from said hook inthe opposite position of said lever permitting the removal of said heel.'

4. In a' shoe having a removable heel, means for locking said heel on said shoe, said means including an apertured recessed plate in said shoe, a bolt on saidv heel extending Vupwardly through said plate, a lever pivotally mounted on said bolt above said plate intermediate the length of saidy plate in one position of said lever for locking said heel on said shoe, said lever in another position thereof permitting the removal of said heel from said shoe.

5. In a shoe Ihaving a removable heel releasable means for locking said heel on said shoe, said means including a recessed plate in said shoe, said plate formed with an annular opening therethrough and an oiTset opening on one side of said annular opening communicating therewith, a bolt rotatably carried by said heel, a squared shank on said bolt extensible through said openings in one rotated position thereof, said shank partially overlying said plate in other rotated positions holding said heel against removal, a lever pivyotally engaging said shank, a cam on said lever engageable with said plate in one pivoted position of said lever tensioning said bolt between said heel and said plate, said lever in another 6 position permitting rotation of said bolt and removal of said heel.

6. In a shoe having an upper, a sole, and a removable heel, a bolt on said heel extending upwardly therefrom, a plate in said shoe formed with an upwardly opening recess therein, said bolt engageable through said recess, a lever rockably carried by said bolt for securing said heel to said shoe in one pivoted position thereof.
