,Figure 2 is a vertical sectional view shown as taken on line Evy-2 of Figure 1-;

Figures 3 and 4 are side elevation and top plan views of one of the operating parts used in connection with theinven-tion; and.

Figures 5, tollinclus' veam elevations; of several other parts used inconnection with the invention. 'j r j l v Description Asmwi-ll be seen from the drawing, -the several strluctiorr of a shoe l5 and the parts utilized for operating when desiring to removably attach or detach secondary heels of varying heightsto a fixed heel portion [6. As will be readily seen the portion or a shoe illustrated may be: adapted fonuse by women, though it is to beu'nderstood thatthe invention is not necessarily restricted; towwomens shoes, asikthe invention very conveniently can be; usedin the construction of shoes for m enyas: Welland for many purposes. The showing of the shoe l5 and fixed heel portion lfi includes the usualzinsole l1, outer sole l8 and backportiorilQ.

In: carrying out the invention the fixed heel portion Hi may be conveniently attached to the back of the shoe in accordance with'methods employed in manufacturing shoes and as will be understood by those skilledin the art. Said fixed heelm-ayconveniently? be provided with at.

recess ZEI- and as providing ashoulder 21; which extends from the insidepart thereof-j and outwardly towards the back part with the recess extending all the way tothetop of the heel thereby 1 providing an; open front; and topfor substantially the widthioi said-heel; Said: heelmay preferably be provided with an angularly disposed opening 22- extending upwardly from the bottom of the: heel to the shoulder portion 2| andtowards the outer part thereof, the purpose of Y which will hereinafter be-describedu Other open ings 23 and 24 likewise areprovided said fi-Xed heel, with the on said opening 23-being towards theinner side of the heel and the other said opening. approximately centrally of said heel-.1 In the construction of the shoe and fixed'heel there may be provided a shankziron- 25 with its forward part imbedded between the; inner sole I 1 and:

outer Solo 18. The said shank iron towards its other end is shaped to provide a pai-rof downwardly bent ears 2B, 26 along the edges thereof with each said ear having a hole 2'l,through whichris inserted a pin 28- thereby allowing the shank to beapivoted and adjusted as desired. Ad-

; jacent the outer ends-of the said shank iron an elongatedopening- 29 is, provided. The shank ironprotruding away from the earsZB 26 towards the outer end may normally be angularly disposed so as toengag a metal or the like plate 311 held fast with respect to the shoulder 2i by virtue of a bolt 3| extending upwardly through the opening 23. i

A bolt 32 is loosely inserted in the opening 22' of the fixed heel I6 and threaded upwardly throughtheplate 3|]. The upper end of said bolt 32 preferably is of adiameter slightly less than the body portion with said part passing through the openingzll of. the shank iron and providing a further reduced portion to which a collar 33 may b securely attached. Since the portionof the bolt passing through the elongated opening 29 is of a reduced diameter there will beysufiicient clearance on either side whereby when the shank is adjusted to a raised position by virtue of adjusting the threaded bolt 32, the clearance will allow proper adjustment. 5

As shown in Figure 1 a low heel 34 is illustrated as removably attached to the fixed heel l6 and which may be considered an important feature of the present invention. The showing is of a low heel or cuban heel and is provided with a lift 34" on the bottom thereof; An opening 35 extends centrally and inwardly from the inner wall-towards theback part of the heel and a vertically disposed rectangular opening 36' extends upwardly from the bottom of the heel to the top and preferably bisects the horizontal opening 35. Said rectangular opening 36 in practice is in registration with the opening 24 of the fixed heel it. A hollow rectangular shaped tubular member 33 is secured within the vertically disposed opening 36' and preferably extends the entire thickness of said heel, but not including the lift 34'. Said member preferably may be provided with a cut-away portion 37 substantially the width of said member and terminating approximately midway of the member and providing a shoulder 33 with said shoulder centrally of the opening 35. Another opening 39 is provided on the side opposite to the opening 31 and may be of a siz approximately one-half that of the said opening 31. This second opening likewise preferably terminates about midway of the member and as providing a shoulder in registration with the shoulder 38. The said member 36 is held fast with respect to the opening 36 with the larger opening 3'! preferably facing towards the inner side of the heel and th smaller opening 39 facing the back of the heel.

Another feature of the present invention resides in the means utilized in removably looking a low or high heel to the fixed heel l6 of the shoe l5. Such means preferably comprises a locking member or plunger 40 of a length less than the length of the horizontal opening 35 and preferably engages a coil spring il placed in the said opening. This said plunger fill approximately midway may be provided with a notch 42 which extends substantially the diametrical thickness of the plunger and a second notch 43 adjacent the said first notch of a depth approximately one-half the diameter of the plunger. Both said notches in actual practice engage the respective openings 31 and 33 of the member 33 when desiring to attach or detach the heel 34 from the shoe.

Other means extend downwardly from the fixed heel l6 through the vertical opening 24 and the opening 36' of the removable heel. Said means preferably comprises a T-shaped member 34, clearly shown in Figures and 6, and at one end of the top part thereof is bent upwardly to form a pair of ears d5 having openings 43. These ears and openings as shown in Figure 2 register with the ears 26 and openings 21 of the shank 25 and preferably support the shank iron by virtue of the pin 28 which allows a swinging movement of the shank when the bolt 32 is adjusting said shank in either upward or downward direction. The end opposite to the ears 35 is fiat and is provided with ,a hole l! and is juxtaposed to the shoulder 2| with the plate 32 overlying a portion thereof. The hole M is in registration with the opening 23 and held fast to the shoulder and plate 30 by the bolt 24 thereby preventing any lateral or other movement of the T-shaped member when the shank iron 25 is being adjusted.

A stem 43 integral with the top portion of the T-shaped member M extends downwardly into the opening 36 and is of a width substantially that of the inside diameter of the tubular member 33. Said stem at its lower end is provided with an open slot 49, the top of which protrudes slightly beyond the notches 42 and 43 and openings 31 and 39 and thereby prevents dislodgement or removal of the plunger 43 from the heel. A notch 50 may be provided on the one side of the stem and extending cross-wise of the slot 49 and functions as a stop for the inward and outtil) ward thrust of the plunger 40 when under the influence of the coil spring il.

In carrying out the invention and when desiring to attach heels of varying sizes, the forward portion of the shoe may first be adjusted to accommodate such heels. If a high heel is to be attached, as shown in dotted lines of Figures 1 and 2, the bolt 32 is screwed upwardly which will raise the rear end of the shank iron 25 to its uppermost position. When the rear end of the shank iron is thus raised, the forward portion of the shoe will be lowered by virtue of the pivoted connection and will assume the position as shown by the dotted lines of Figure 1. Since the forward part of the shoe has been properly adjusted the heel may now be attached. The plunger 40 is pressed inwardly so that the larger notch 42 will be past the larger opening 31 of the tubular member 36 and at the same time be in engagement with the notch 59 of the T-shaped member M. Upon releasing the inwardly directed pressure of the plunger, the said plunger under influence of the spring ll will snap back into normal position and the smaller notch 43 will then engage the smaller opening 39 of the member 36 thereby securely locking the heel to the fixed heel E6 of the shoe. When desiring to remove either the high or low heel from the fixed heel portion, the same procedure as that for attaching the heel may very conveniently be followed and proper adjustment of the forward part of the shoe be carried out before attaching another heel.

Obviously detail changes and modifications may be made in the construction and use of my improved shoe Without departing from the spirit and scope of the invention, and I do not wish to be understood as limiting myself to the exact construction or operation shown or described except as set forth in the following claims when construed in the light of the prior art.
