2 Patented Feb. 27, ,967 UNITED STATES PATENT OFFICE 1948,967 REMovABLE SHOE HEELAND LIFT Bern Jassen, Brooklyn, N. Y. Application May, 29, Serial No. 673,412 l 1 Claims. (C ) In U. S. Letters Patent No. 1,888,76, dated November 22, 1932, there is shown a detachable heel lift for 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 pro vide an article of footwear having a dietaehable heel which may be readily removed by the wearer and be replaced with another heel, without hav i) 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 man lis terial, becomes broken. When either of these oc curs with the common type of footwear it is nec essary to take the shoe to a shoe maker or cobbler to have the heel repaired or replaced. Where the latter is necessary the cobbler is not likely to have ) in stock a heel of the right shape, finish and color to replace the broken One; and it is necessary to Send the shoe back to the manufacturer or to dis card the pair of shoes completely. Where shoes are supplied with the present in $ vention the user may readily detach a broken heel. and replace it with a new one with no more tools than a screw driver or the end of a shoehorn. 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. Or, multiple sets of heels of relatively different shapes or heights may be supplied for the same pair of shoes so that the user may obtain different combinations o' heels and footwear. Or, a dealer may alter the heels of any pair of shoes to obtain different color combinations to suit the tastes of customers with 0 out having to carry in stock a multitude of indi vidual styles. The present invention provides means for read ily and easily detaching the heel from the shoe to obtain any of the results referred to, and a new or different heel may be readily 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 from the ap pearance of the shoe. 0 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. The other branch of my invention relates to a simple means for detachably securing the lift to the heel. Lifts wear down either across the whole bottom surface or at one side 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 WOm- 60 en's shoes where the wearing area is very small;. and it is necessary for the wearer to have a cob bler put on new lifts at these frequent intervals. This is both inconvenient and expensive. With the present invention the user, without 6 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 cents a pair be cause the lifts alone may be sold at a price of a few cents a pair. The wearer may find upon dressing for Some Occasion and at 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 present invention so far as 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 pro vide means for engaging this lateral extension to prevent the sleeve from turning. This is espe cially important where the detachable heel feature is employed with the detachable lift feature, because the sleeve is prevented from turn ing or shifting when the heel securing nut is being tightened. It also prevents the sleeve turning when the lift holding member is turned in rela tion to the heel. The means for preventing the sleeve from turning in the heel preferably cone sists of pins driven into the heel and extending 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 the bottom of the plunger and therefore near the lift.. Another object is to provide more encient and,100 : simple means to hold the lift retaining member separated from the end of the heel while a lift is. 10 being removed or applied and to position this means at the lift end of the device. Another object is to permit the plunger which carries the lift to be turned in either direction when drawn out, and to have the plunger held Out regardless of which direction it is turned. The turning of the plunger when it is pulled out and

3 i V Gh 2 turned has no tendency to turn the sleeve in the heel bore..... Another object is to provide a lift which may is 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 in the lift itself, which is especially economical Where the lift is made of leather. Another object of my invention is to simplify and reduce the cost of the parts and to simplify and cheapen the cost of assembly. Other ad vantages will be set forth in the following de tailed description of the invention. In the drawing forming part of this applica tion, Figure i is a plan view of the rear or heel portion of a woman's shoe or Oxford, with the inner lining partly lifted to show the nut which is part of the heel securing means, Figure 2 is a longitudinal Sectional view taken on the line 2-2 of Figure 1, Figure 3 is a detail sectional view, taken on the line 3-3 of Figure 2, Figure 4 is an elevational view, the major por tion of which is broken away and showing the heel and lift attaching parts on an enlarged scale, Figure is an assembly view of the device, Figure 6 is a perspective view of the sleeve, Figure is a perspective view of a stamped form of plunger,???- Figure 8 is an inverted view of a modified form of lift, - Figure 9 is a sectional view taken on the line 9-9 of Figure 8, and Figure 10 is a side elevation of the lift shown in Figure ' I will first describe the form of the invention shown in Figures 1 to. 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 lifted up to permit access 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 I have shown it as the high or French type. The body of the heel may be made of WOOd, leather or any of the composition materials employed for this purpose and it may be covered with leather, cellu loid or any of the finishing materials commonly used for such purpose. In other words, the heel maybe made according to present practice except that it is provided with a bore, 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 2, to accommodate the bolt. There is a sleeve.7 which has a driven fit in the lower portion of the bore of the heel; and at its bottom end the sleeve has latera wings or flanges 8 which rest against the bottom end of the heel to determine the position of the sleeve in the heel and for another purpose as will appear. The wings or flanges 8 each have an aperture g through with is 0 diver into the body of the heel extend so that these pins prevent the sleeve from turning in the bore. They serve ara additional function, as will appear. The sleeve is rolled or crimped near the bottom 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-, ing held on the plunger by turning over or swag ing the end of the plunger as shown at 1. 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 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 horizon tally 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 the lift. 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 provided with 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 adapt ed to rest with their top edges against the end óf the heel to hold the plunger partially with drawn from the sleeve, as will be described here inafter. -- 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.? On the extreme lower end of the plunger there is a laterally extending plate 2 which is adapted to be received in and preferably fit the pocket 19; and this plate is shown as having the portion 26 which first enters the pocket, 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 the detachable heel feature is employed, the sleeve is extended above the end of the plunger to receive therein the ball 28 which is formed on the lower end of the bolt 29. The end of the sleeve is preferably crimped or spun inwardly as shown at 30 to hold the ball from moving out but permitting it to turn. There is a pin 31 driven through a cross aperture in the ball and the ends of the pin pass through the elongated slots 32 in the sleeve. This pin may rock in orie direction due to the play in the slots 32 while the ball may rock with the pin at right angles to the first movement, thereby permitting a universal movement of the ball.... There is an aperture 33 formed through the heel seat of the shoe, of sufficient diameter to receive therethrough the cylindrical portion 34 of a nut. This nut has a thin top 3 adapted to rest against the top wall of the heel seat under the innerlining 2; and the cylindrical portion extends through the aperture 33 in the heel seat. It has an internal thread 36 for engagement with the external thread 37 of the bolt 29 whereby the nut may be screwed onto the upper end of the bolt. Operation.--In assembling the parts the plung er 13 is inserted into the sleeve 7; then the spring 12 is dropped into the sleeve from the top so that it surrounds the plunger and rests against the, crimped shoulder 11 of the sleeve. The collar 14 is then placed on the upper end of the plunger and is pressed down on the spring 12. While the collar is held dowra, a tool is tapped against the hollowed end of the plunger to turn the edge C r 4.

The plunger consists. 28 may be placed in the upper end of the sleeve of a continuous strip of metal bent back upon and then the end of the sleeve is spun in as at 30 itself so that the superimposed portions form the to confine the ball. Either before or after this is plunger. The two half plates 40 perform the done the pin 31 is driven into the cross aperture Same function as the plate 2 in the first form of the ball with the ends of the pin extending of the invention. The shoulders 41 and 42 per into or through the apertures 32 of the sleeve. form the same functions as the shoulders 22 and The device is now ready to be assembled in the 24 of the first form. There is a collar 43 placed O shoe. The sleeve 7 is driven into the bore of the On the upper end of the plunger for the spring 8 heel until the wings 8 rest against the end of. 12 to rest against and this may be held in place the heel. The top of the heel is now placed by a. pin 44 passing through the loop 46 and against the heel seat 4 of the shoe. The cylin having its ends 47 bent up to prevent the pin drical portion 34 of the nut is passed through from sliding out of place. The plunger and the the aperture 33 of the heel seat and it is turned plate 40 operate the same as in the first form 90 until the threads 36, 37 engage and the nut is of the invention. further turned until the bolt is pulled upwardly In Figures 8 to 10 I have shown a modified, and the nut drawn down tightly against the in form of lift. Where the latter is made of leather side of the shoe, whereupon the heel will be tight the pocket 19 and the slot 20 can not be cast 20 ly clamped in position on the shoe. There are therein. Here I attach a plate 48 to the top of 9 pins or nails 38 in the top of the heel which pierce the lift, preferably by, forming the three lugs 49 the heel seat as the heel is drawn into final po on the edge of this plate, which lugs are forced. sition and these, serve to prevent the heel from through the lift material and clenched as shown. turning about the bolt...? The Space 0 between the plate and the lift forms 2 The top of the nut may be provided with the a pocket corresponding with the pocket 19. The 10C cross slot 39 to be engaged by a screw driver or. slot 1 in the plate 48 serves the same purpose as the edge of a shoe horn, for the purpose of turn the slot 20. This form of lift is applied to and ing the nuut in the manner described. removed from the plate 2 in the same manner The plate 2 is grasped by the hand and i as the first lift pulled away from the end of the heel against By having the bolt 29 connected with the sleeve 10. the resistance of the spring 12 acting on the through a swivel connection, the heel may fit plunger; and when the shoulders 22 have been properly against the heel seat and its position moved out of the slots 23 of the sleeve, the plate controlled by the latter. The heel attaching de-. 2 and plunger 13 may be turned around either vice is useful regardless of whether the heel is 3 clockwise or counterclockwise; and this will bring ever to be removed and replaced, because 1- it pro - the top edges of the projections 22 at such posi vides a stronger and more dependable means for 110 tions that they may rest against the end of the Securing the heel to the shoe. The bolt shown heel. If the plate 2 is now released, the plate herein is stronger and more reliable than the and the plunger will be held in their downwardly means heretofore used for attaching heels to projected position shown in dotted lines in Fig foot wear. The heel is therefore less likely to ure 4. The plate 2 is now spaced from the end of the heel to permit the lift to be attached. The lift is approached to the plate 2 as shown in Figure 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 of the plate stops against the end of the pocket 19. The lift and the plate 2 (and of course the plunger) are now turned until the portion regis ters with the slots 23 in the lower end of the sleeve. Immediately, the plunger is drawn up by the spring 12 until the lift is pressed against the end of the heel by the plate 2. As this action takes place, the pins 9a pass through or into the cut outs 27 of the plate 2 and enter the aper tures 21 of the lift. These pins not only prevent the sleeve from turning or shifting in the heel but they also prevent the lift from turning" or shifting on the heel. The shoe is now ready for 80 wearing. The projection 24 serves to close the end of the slot 20 and prevent the entry of dirt. If it is desired to replace the lift the above operations are reversed. The lift is pulled down from the heel and this carries the plate 2 down wardly,. When the shoulder 22 is flush with Or. below the end of the heel the lift, the plate 2 and the plunger are turned until the shoulder 22 lies and rests against the end of the sleeve, where upon the lift may be released and the plate 2 will be held down. The old lift may be slid of the plate 2 and a new lift placed on it and then -the lift is turned as before to bring the member again into register with the slots In Figures 6 and 7 have shown the detachable lift feature without the removable heel feature. 3. be broken or to come off the shoe. a Having described my invention, what I claim is: * '? 1.
