EXCHANGEABLE HEEL FOR SHOES.

Specification of Letters Patent.

Application filed June l, 1910.

To oZZ 'whom it may concern: v ile it known that i, .SiMoN S'rRoMnR, a citizen of the Kingdom of Austria-Hungary, and a resident of New York, count-y and State oi New York, have invented certaiuhew and useful Improvements in EX-. changeable Heels for Shoes, of which the following is ay specification.

This invention has reference to improve ments in heels for boots and shoes and pertains particularly to exchangeable heels. The heels of this type at present in use are generally made of rubber and secured to the shoe by means of nails, screws, and the like. These are applied for the purpose of preventing` the Wearing ofi' of the heels on one side or in one place thus preserving their original shape. Furthermore the elasticity of the step. The exchangeable rubber heels are found in the market ready to be applied but have the drawback that their application requires in most instances the services of a skilled Workman.

t is the purpose oi the present invention shoes of such construction that same may This has been primarily attained by the use of a lower heel part which normally is in contact with the Ground. This part is made of leather or rubber and of such shape that simply turning a specially constructed locking .device forming part ot 'the novel heel. By simplicity in construction it has been duce a neat and vdurable article which Wears ofi uniformly, all as will be fully described hereinafter with reference to the accompanying drawing in which:

Figure 1 represents in bottoni view a holding' plate on the heel of the shoe. Fig. 2 shows saine in front vienT with the heel thereto attached. Fig. 3 illustrates in top plan view the exchangeable heel with iasteninii` plate. Fig. 4 is a cross section on line A---B of Fig'. 8. Fig. 5 is a ton nlan 'view ot' the locking device. Fig. 6 is a cross section on line Cml) of Fig. 5 and Fig. 7 is a Vertical cross section of the en-A tire heel as applied to the shoe.

Similar characters of reference denote like parts inall the figures.

tachedrto the shoe -is designated by the numeral 1. The holding plate 2 is preferably made of metal and secured to the heel 1 by means of nails 4driven through the holes 3. The lower layer of the heel has centrally a round opening 'through which the special locking device fl passes as 'will be :fully de-. scribed further below. Underneath the holding; plate 2 there is screwed into the heel 1 the locking device d by means of the screw G on which same turns as upon a pivot. The projection 7 or the locking,r device #l passes through the opening 5 of the holding plate 2 shown in Fig. 1 and extends on theinner side of the heel at aright angle and forms at the end a catch 8. The holding plate 2 'further is provided With elongated slots 9 radially arranged, see Figs. 1 and 7. The exchangeable heel 10 comprises a fastening plate llfwhicn is stamped out to form hook shaped ears 12. The slots 9 have the purpose of allowing the ears 12 to pass Whose rectangular portions pass be yond the plate 2 While pressing the exchangeable heel 10 to the holding plateand into the heel 1,

The fixing of the fastening plate 11 to the exchangeable heel 10 may be easily accomplished vby stamping -from said pla-te nail like projections 13`wl1ich enter into thcexchangeable heel 10 when both are pressed together. in case the exchangeable heel part is to be' made of rubber, molten rubber is preferably poured upon the fastening 'plate 11 so that the latter is embedded in the rubber. f

The specially constructed locking device 4l, shown in detail in Figs. 5 and 6 which is devised for securing the exchangeable heel part l() to the heel 1 consists of a metal plate which may be turned around the screw 6 by means of the projection 7 with its end hook 8. On the circumference of the locking device there are notches 14 corresponding in number and location to the ears 12. These notches cprrespond to the slots 9 of the holding` plate 2, as may be seen by comparing Figs. 1 and 5,-and when in a certain location the ears 12 may pass through both. lf however the locking device 4 is turned by means of the catch 8 into the position shown in Fig. 1 the tooth like edges formed by the notches 14: enter the notches 16 of the ears l2. In this manner the fastening 'plate 'll as well as the exchangeable heel part 10 In the drawing the heel permanently atare locked, see Figs. l and 7. ln order to attach the exchangeable heel securely to the heel 1 the tooth like edges of the locking device l are provided with indent-ations,- see Fig. 6 preferably produced by pressing so that thateeth next to the notches 14 of the locking device shall still be on the same level. with the latter but progress in the direction ofthe arrow see Fig. 5 whereby the heels are gradually forced together and the level of the teeth 15 meets the level of the locking device 4C at a certain angle. In

i this manner these teeth 15 during the turning of the locking device 4. draw the ears 12 forcibly into the heel 1. In the holding plate there are further produced holes 17 adapted to receive the semi-circular projec# tions or ends 18 of the fastening plate 11.

" l/Vhen the projections 1,8 are located in the l vice underneath same.

holes 17 their coperation prevents the turning of the exchangeable heell on the heel 1 and thus the ears 12 and the locking device et are subjected to less strain. Instead ofthe holes 17 indentations may be produced in thc'holding plate 2 which have the same edect. `Likewise the holes 17 may be produced in the fastening plat-e 11 and the projections 18 on theholding plate 2 which answers the same purpose.

The exchangeable heel 1() is applied to 'the heel 1 in substantially the following off by operations performed in reverse order. y

The fastening parts of the holding plate Q, the fastening 'plate 11- and the locking device 4 are of uniform shape which presents the great advantage that the exchangeable heels 10 are interchangeable on the same pair of shoes whereby the heels may locA worn off equally until completely used up.

I claim as my invention:

1. In combination with a boot or shoe, a holding plate secured to the heel having elongated slots radially arranged and a larger slot near its inner portion,l a locking Adevice rotatably mounted within the heel provided with marginal notches and a lateral projection extending through the large f slot of the holdin plate, in combination with an exchangeab e heel comprising a fastening plate, hook shaped ears formed integrally with said fastening plate and adapted to pass through theradial slots of the holding plate andthe notches of the lbcking device so that upon` turning the latter the exchangeable heel is iirmly attached.

2. ln combination with a boot or shoe, a

'holding plate secured to the heel having elongated slots radially arranged and a 4larger slot near its inner portion, a locking device rotatably mounted within the heel provided with marginal notches forming slightly inclined teeth and a lateral projection extending through the large slot of the holding plate, in combination with an exchangeable heel comprising a fastening plate, hook shaped ears formed integrally with said fastening p` te, and adapted to pass through the radial slots of the holding .plate and the notches of the locking device so that upon turning the latter its teeth like edges enter the notches of the hook shaped ears under a slight angle whereby the exchangeable heel is firmly attached.

3. In combination with a boot or shoe a.

holding plate secured to the Aheel having elongated slots radially arranged, small holes and a large slot near its inner portion, a locking device rotatably secured within the heel provided with marginal notches forming teeth like portions under a slight angle and having a lateral projection extending through the large slot of the holding plate, in combination'with an exchangeable heel comprising a fastening late withl hook shaped ears formed integrally therewith and having spherical projections corresponding in number and location to the holes of the holding plate of the heel,v so arranged that the ears may pass'through the radial slats of the holding plate and marginal notches of the locking device and upon turning the latter its teeth like portions engage the' notches of the ears and the spherical projections lodge in the holes of the holding plate of the heel.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. A y
