BEMOVABLE SHOE HEEL AND LIFT Bern Jassen, Brooklyn, Y,

Application May.29, 1933. Serial No. 673,412

l1': claims. c (o1. 36-42) in U.- s'. Letters Patent No. 1,883,765, dated November 22, 1932, there is shown a detachable heel llftfor shoes and the present invention,

among other things, embodies improvements over.

t'- the article shown in said patent.

One object of the present invention is to provide an article of footwear having va detachablev heelwhich may be readily removed by the wearer and be replaced with another heel, without havl') ing to resort to the services of a shoe maker or cobbler. In some instances, especially with the heels commonly worn by women, the heel becomes detached from the shoe, or the `heel body, usually made of wood, leather, or some composition mal terial, becomes broken. When either of these occurs with the common type of footwear it is necessary to take the shoe to a shoe maker or cobbler to have the heel repaired or replaced. Where Athe latter is necessary the cobbler is not likely to have in stock a heel of therlght shape, finish and color to replace the broken one; and it is necessary to send the shoe back to the manufacturer or to discard the pair of shoes completely.

Where shoes are supplied with the present inand replace it with a new one with no more tools than a screw driver or the\end of a shoe horn. If desired, the user may be supplied with more than one pair of heels for one pair of shoes, which heels may be of different colors to obtain different color combinations and the user may attach either set of heels to the shoes. O'r,'mu1tiple sets of heels of relatively dilferent shapes or heights may be supplied for the same pair of shoes so that 'f the user may obtain different combinations of heels and footwear. Or, a dealer may alter the heels of any pair of shoesto obtain diiferent color combinations to suit the tastes of customers without having to carry in stock a multitude of individual styles.

The present invention provides means for readily and easily detaching the heel from the shoe to obtain any of the results referred to, and a new or different heel maybereadily applied to replace the one removed. The present device for-secur. ing the heel to the shoe is invisible when the heel is applied so that it does not detract fromthe appearance of the shoe. Y

In the fullest embodiment of my invention the means for detachably securing the heel to the shoe is combined with the means for detachably securing the lift to the heel so that some of the parts are common to both devices.

Th other branch of my invention relates to vention the user mayreadily detach a broken heel a simplev means for detachably securing the lift to the heel. Lifts wear down either across the whole bottom surface or at o'nepside or the back, very quickly and if not renewed the shoe may be thrown out of shape. In some cases a lift may wear only a week or two, especially on womens shoes where the wearing area is very small; 1 and it is necessary for the wearer to have a cobbler put on new lifts at these frequent intervals. This is both inconvenient and expensive.

With the present invention the user, without any tools whatever, may, in a matter of seconds, remove the worn lifts and replace them with new ones, and at a cost of only a few centsa pair because the lifts alone may be sold at a rprice of a few cents a pair. The wearer may iind upon 7'0 dressing for some occasion and lat a time when no cobbler is available, that the lifts are Worn on the shoes she most desires to wear. If they are equipped with the present invention it is only a matter of seconds to change the lifts.

One object of my presentinvention so far Vas it relates to the lift device is, to provide a lateral extension on the lower end of the sleeve which is forced into the bore in the heel body, and to provide means for engaging this lateral extension to prevent the sleeve from turning. This is especially important where the detachable heel feature-is employed with the detachable lift feature, because the sleeve is prevented from turning or shifting when the 'heel securing nut is being 85 tightened. It also prevents the sleeve turning when the lift holding member is turned in relation to the heel. p The means `for preventing the sleeve from turning in the heel preferablyconsista ofdpins driven into the heel and extendingl through the sleeve extension referred to, these pins also projecting into apertures in the lift to prevent the latter from turning or shifting while in operative position.`

, Another object is to arrange the means for preventing the plunger which carries the lift from turning when in operative position. at a point near thev bottom of the plunger and therefore near the lift. Another object is to provide `more emcient andy l simple means to hold the lift retaining memberI 1 tion,

2, to accommodate the bolt.

turned has no tendency to turn the sleeve in the heel bore.

Another object is to provide a lift which may be made of leather and having 'a plate attached thereto to cooperate in forming the slot and pocket for receiving the lift holding plate. This makes it unnecessary to form the pocket and slot vantages will be set forth in the following detailed description of the invention.

I 'will rst describe the form of the invention shown in Figures 1 to 5. I have shown only the rear portion of heel 1, of a shoe or oxford such as are worn by women, as the remainder of the article may conform to present practice.' The inner 'lining 2 has been liftedup topermit accessY to the securing nut. The heel 3 which' is fitted to the heel seat 4, may be of any shape so far as. the present invention is concerned and In have shown it as the high or French type. The body of the'heel may be made of wood, leather or any ofthe composition -materials employed for this purpose and it may be covered with leather, celluloid or any of the finishing materials commonly used for such purpose. In other words, the heel may-beamade according to present practice 'except that it is provided with a bore 5, -which, .if all the` features of my invention are'used. will extend from the bottom end of the heel right through to the top. Preferably, the upper portion'6 of the bore is widened or enlarged and it is inclined at an angle to the lower portion as shown in Figure There is a sleeve 7 which has a driven fit in the `lower portio of thebore 5 ofthe heel; and at its bottom end the sleevehas lateral wings or flanges 8 which 4rest against the bottom end of the heel to determine thepositlon of the sleeve in the heel and for anotler purpose as will appear.

The wings or anges 8 each have an aperture thlugh which pins 10, ldriven into the bodyr additional function; as will appear.

ofthe heel extend so that these pins prevent the sleeve from turning in the bore 5; They serve The sleeve 7 is rolled or crimpedA near the lbottom edge as-shown at 11 to form an inner projection to provide an abutment for one end ,of the coiled spring 12. This spring surrounds the plunger 13 which extends into the bore of the sleeve. The other end of the spring abuts against the collar 14 on the upper end of the plunger, the collar be-y ing held on the plunger by turning over or swaging the end of the plunger as shown at l5. An indentation 16 may be provided in the end of the plunger to facilitate this swaging operation. The spring has a tendency to force the plunger upwardly within the sleeve.

The heel lift shown in Figures 1, 2, 3 and 5 is shown as having a straight or slightly curved front edge 17 to conform with the breast of the heel; and it has rounded side and rear edges 18 to conform with the contour of the lower end of the heel. The lift is of uniform thickness. It is provided with a pocket 19 extending horizontally inwardly from the front edge 17 and there is a slot 20 extending .from the front edge 17 which slot extends from the pocket 19 to the top of thelift. There are recesses 21 formed in the top side of the lift, shown at opposite sides of the slot 20 to receive the lower ends of the pins 9a.

The lower end of the plunger is providedwith a shoulder 22, preferably/two of them disposed at opposite sides of the plunger, which are adapted to move into the slots 23 in the ends of the sleeve 7 when registered therewith, but which are adapted to rest with their top edges against the end f the heel to hold the plunger partially withdrawn from the sleeve, as. will be described hereinafter. i

There is another shoulder 24 on the plunger, the purpose of which is to close the front end of the slot 20 of the lift when in operative position, to exclude dirt from the inner parts.

Qn the extreme lower'end of the plunger there is a laterally extending plate 25 which is adapted to be received in and lpreferably nt the pocket 19; and this plate is shown as having the portion 26 which first enters-the pocketr 19 rounded. This plate has cut outs or recesses 27 to permit the pins 10 to pass therethrough and enter the recesses 21 of the lift. Where thef detachable heel feature is employed, the sleeve is extended above the end of theplunger to receive therein the ball 28l which lis formed on the lower end of the bolt 29. The

end of` the sleeve is preferably crimped or spun inwardly as shown at 80 to hold the ball from moving'Y out but permitting it to turn. There is a pin 31 driven through a cross aperture in the ball and the endsof the pin pass through the elongated slots 32 in the sleeve. This pin may rock inorie direction due to the play in the slots 32 while the ball may rock withthe pin at right anglestothe first movement, thereby permitting a universal movement of the ball.

y .There is an aperture 33 hformed through the heel seat of the shoe, of suiiicient diameter to receive therethrough the cylindrical portion 34 of a nut. This nut has a thin top 35 adapted to rest againstthe top wall of the heel seat under the inner lining' 2;. and the cylindrical portion extends through the aperture 33 in the heel, seat. It has an internal thread-'36 for engagement with the vexternal thread 37 ofthe bolt 29 whereby the nut over above the collar as shown at 15. The sleeve, spring and plungerare now assembled; The ball 28 'may be placed in the upper vend of the sleeve and then the end of the sleeve is spun in as at 30 to conine the ball. Either before or after this is done the pin 31 is driven into the cross aperture of the ball with the ends of the pin extending into or through the apertures 32 of the sleeve.

The device is now ready to be assembled in the shde. The sleeve '7 driven into the bore 5 of the heel until the wingsy 8 rest against the endof. the heel. The top of the heel is no'w placed against the heel seat 4 of the shoe.' The cylindrical portion 34 of the nut is passed through the aperture 33 of the heel seat and it is'turned until the threads' 36, 37 engage and the nut is further turned until the boltis pulled upwardly and the nut drawn down tightly against the in' side of the shoe, whereupon the heel will be tightly clamped in position on the shoe. There are pins or nails 38 in the top of the heel which piercel the heel seat as the heel is drawn linto final position and these. serve to prevent the heel from turning about the bolt. y

The top of the nut maybe provided with the cross slot 39 to be engaged by, a screw driver -or the edgeof a shoe horn, for the purpose of turning the nut in the manner described.

The plate 25 grasped, by the hand and yiS, pulled away from the end of the heel against the resistance of the spring I12 acting on the plunger; and when the shoulders 22 have been moved out of the slots 23 of the sleeve, the plate 25 and plunger 13 may be turned around either clockwise or counterclockwise; and this will bring the top edges of the projections 22 at s uch positions that they may rest against theend 0I Athe heel. If the plate .25 is n ow released, :the plate and the plunger will be held in their downwardly projected position shown in 'dotted lines inFigure' 4. The plate 25 is now spaced fromthe end of the heel to permit the lift to be attached. The

lift is approached tothe plate 25 as shown. in iS Figure 5 and it.is pushed onto the plate so `that the latter enters the pocket 19 and the portion enters the slot 20 until the end ofthe plate sto'ps against the end of the pocket 19.

The lift and the plate 25 (and of course the plunger) arenow turned until the portion registers with the slots 23 in the'lower end of the sleeve. Immediately, the plunger is drawn upjby the spring 12 until the lift is pressed against the end of the heel by the plate 25. As this action takes place, the pins 9a pass through or into the cut outs 27 of the plate 25 and enter the apertures 21 of the lift. These pins not only prevent the sleeve fromturning or shifting in the heel but they alsol prevent the lift from turning'or shifting on the heel. The shoe is now ready for wearing. The projection 24 serves to close,- the. end of the slot 20and prevent the entry of dirt.

Ifit is desired to replace the lift the aboveoperations are reversed. The lift is .pulled down from the heel and-this carries the plate 25 downwardly. l When the shoulderl 22 is ush with orbelow the end of the heel the lift, the plate y25 and the plunger are turned until the shoulder 22 lies and rests against the end of the sleeve, whereupon vthe lift may' be released `and the plate 25 will be held down. 'Die old lift'may be slid ol! the plate 25 and a new lift placed on it and then ntheelift isV turned as before to bring the member again into register with the" `slots 23. In Figures Band 7 l have shown the detachable Herein the sleeve [I is the samef as before except' that it. need not be as long. The plunger consists- -of a. continuous strip of-metal bent yback upon itself so that the superimposed portions form the plunger. The two half'plates 40 perform the same function as the plate 25 in the iirst-forrn of the invention. The shoulders 4l and 42 perform the same functions as the

shoulders

22 and 24 oi' the first form.- Thereis a collar 43 placed on the upper end ofthe plunger for the spring 12 to rest against and thismay be held in place? by a. pin 44 passing through the loop 46' and having ,lits ends 47 bent upto prevent the pin from 'sliding' out of place. The plunger and the plate 40 operate the same as inthe first form of the invention.

In Figures 8 to 10 I have shown a modined form of lift. Where the latter is made of leather the pocket 19 and the slot 20 can not be cast therein. Here I attach a plate 48 to the top of the lift, preferably by forming the three lugs 49 on the edge of this plate, which lugs areforcedthrough the lift material and clenchedas shown.

The space 50 .between the plate and the lift forms controlled by the'latter.' The heel attaching de- I vice is useful regardless of whether 'the heel is ever to be removed and replaced, because vit provides a stronger and more dependable means for securing the heel to the shoe. The bolt shown herein is` stronger and more reliable than the means heretofore used for attaching heels to foot wear. The heel is therefore less likely to be'broken or to come olf the shoe.
