Patented Feb. 13, 1934 UNITED STATES PATENT OFFICE REENFORCED HEEL LIFT AND ATTACHING MEANS THEREFOR Application May 4, 1932. Serial No. 609,211

8 Claims.

This application pertains generally to the same subject matter as my U. S. application Serial No. 526,079, filed March 28, 1931 and issued May 31, 1932 as Patent 1,861,118.

One object of the invention is to provide anew and improved reenforced heel lift which may be quickly and easily attached to the heel, will remain securely in place, and may be easily removed when a new lift is to be substituted.

Another object of the invention is to provide a novel dowel pin for reenforcing the heel and receiving the lift-attaching fastenensaid dowel pin being provided with a downwardly projecting stud which is receivable in an opening in the lift reenforcement to assist in holding the lift in place.

Yet another aim is to provide a construction which readily permits attachment of alift of one size to a heel having a smaller lower end, even if the lift must project rearwardly from the heel to be cut or trimmed off.

.A further aim is to provide a dowel pin to receive the lift-attaching fastener, provided with a nail-receiving split in its lower end, and to snugly surround this split pin end by a sleeve, said sleeve serving to hold said split end of the dowel pin against expansion when the nail is driven, so that the nail will tightly engage the side walls of the split and there is no danger of so expanding the split end of the pin, as to split the wooden heel.

Yet another aim is to provide a construction which may be easily and inexpensively .manufactured and marketed and hence sold at small cost.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Fig. 1 is a vertical sectional view through a wooden heel, a lift of proper size for said heel, and the improved attaching means securing heel and lift together. I

Fig.2 is a view similar to Fig. 1 but showing the lift applied to a relatively smaller heel so that said lift must project rearwardlyfrom the heel to be trimmed off.

Fig. 3 is a view similar to Fig. 2 but showing the lift applied to a smaller heel in a position from which it must be moved rearwardly so that the upwardly projecting flange of the lift-reenforcing plate will abut the breast of the heel. Then, the projecting stud of the dowel pin should fit into the second hole of the lift and reenforcing plate and the nail should be driven into the third hole.

Fig. 4 is a perspective view of the dowel pin shown in Figs. 1, 2 and 3.

Fig. 5 is a perspective view of the lift reenforcement shown in Figs. 1, 2 and 3, the lift being shown in dotted lines.

Fig. 6 is a perspective view showing a different lift reenforcement, the lift being here again shown in dotted lines.

Fig. 7 is a perspective view showing a still different reenforced lift.

Fig. 8 is a perspective view of a reenforcement used in the lift of Fig. 7.

Fig. 9 is a perspective View partly in section, showing one of the split dowel pins and the sleeve which holds its split end against expansion.

Fig. 10 is a perspective view illustrating a split of difierent shape than that shown in Fig. 9.

Fig. 11 is a detail vertical sectional view showing a reenforced lift attached by means of a flat nail and a dowel "pin similar to those shown in Figs. 9 and 10, but provided also with a downwardly projecting stud similar to the one shown in Figs. 1 to 4.

Fig. 12 is a horizontal sectional view on line l2--12 of Fig. 11.

Fig. 13 is aplan view showing a reenforcement slightly different from that shown in Fig. 12.

Fig. 14 is a perspective View showing a still different reenforcement.

Fig. 15 is a perspective view of the in Figs..11 and 12.

Figs. 16 and 17 are perspective views of tools usedfor driving the dowel pins into the heels without danger of injuring the projecting studs of said dowel pins.

The construction shown in Figs. 1 to 5 will first be described. In these views, 20 denotes a conventional wooden heel which is reenforced by a metal dowel pin 21 snugly driven into a bore of said heel, said dowel pin being provided with a longitudinal opening 22 extending upwardly from its lower end and being provided on said lower end with a downwardly projecting stud 23. Preferably, the pin 21 is provided with sharp ridges 24 which bite into the heel 20 and hold said pin against accidental rotation.

25 denotes a lift preferably formed from rubber or suitable composition. Imbedded in this lift between its upper and lower sides but rather close to the former, is a reenforcing plate 26 which is preferably of the cross shape shown, said plate being provided with a forwardly projecting neck 2'7 having an upstanding transverse flange 28 to abut the breast of the heel 20, when the lower end of this heel is of proper size for the lift 25. On upwardly converging lines 29, the

nail shown flange 28 is weakened, so that its corner portions may be readily broken off or cut off, should it be required that the flange be of semi-circular shape, required for some heels.

The plate 26 is formed with three openings 30, 31 and 32, these openings, the stud 23, and the opening 22, being all of the same diameter. The lift is provided with openings 30, 31' and 32' in alinement with the openings 30, 31 and 32. When the heel and lift are of proper relative sizes, as seen in Fig. 1, the stud 23 is received in the rearmost opening 30 and the attaching nail 33 is driven through the openings 31' and 31, into the opening 22. When the lower end of the heel 20 is relatively smaller and the lift 25 must project rearwardly therefrom to be trimmed off as seen in Fig. 2, the stud 23 is received in the opening 31, and the nail 33 is driven through the openings 32 and 32, into the opening 22. The nail always frictionally engages the wall of the opening 22 to tightly hold the lift in place, and the stud 23 and its receiving opening co-act to hold said lift against any tendency to rotate about said nail, also holding the lift against pounding forwardly under the action of walking.

In Fig. 6, a different reenforcing plate 34 is provided, imbedded primarily in the upper face of the lift 35. The three lateral wings 36 of this plate are of dove-tail form and are provided with dove-tail extensions 3'7 projecting upwardly and imbedded in the lift 35. A similar extension 38 is formed on the rear end of the plate 34, and the neck 39 at the front end of this plate is provided with a flange 40 having the same function as the flange 28. The openings 41 through the plate and lift perform the same functions as the openings 30, 31 and 32, above described.

In Figs. 7 and 8, the lift 42 is provided with a reenforcing plate 43 similar to the plate 26, but instead of forming this plate with three entirely separate openings such as 30, 31 and 32, it is formed with three openings 44, 45 and 46 which communicate with each other and register with a similarly shaped slot 47 in the lift 42. This construction allows attachment of the lift in the same manner as above described, but also allows a flat nail to be used if desired, instead of a round nail. When the flat nail is used, a dowel pin such as 48 of Figs. 9 and 10, is employed. The lower end of this dowel pin is formed with a split 49 having a reduced inner end 50, and to prevent said split end of the dowel pin from expanding when the nail is driven, a metal sleeve 51 snugly surrounds the lower end portion of said dowel pin, said sleeve being provided with a flange 52 to lie upon the bottom of the shoe heel. The flat attaching nail is of course of such size that while it will enter rather freely into the large lower end of the split 49, it must be forcibly driven into the reduced end 50, such tenacious anchoring of the nail being thus effected, as to securely anchor the lift to the heel. Such spreading or expansion of the dowel pin as to decrease the friction between the pin and the nail, is prevented by the sleeve 51. Moreover, this sleeve prevents such expansion of the split dowel pin end, as to split the wooden heel.

In Figs. 11 and 12, a dowel pin 52 is shown similar to the pin 48 and surrounded by a sleeve 53, the lower end of said pin however being provided with a downwardly projecting stud 54 similar to the stud 23. The lift 55 is provided with a reenforcing plate 56 having a transverse slot 57 to receive the flat attaching nail 58, and said plate is also formed with a small opening 59 to receive the stud 54. The head 60 of the nail 58 is countersunk into the lift 55 and is of such size as to cover and protect the stud 54.

In Fig. 13, a plate 61 is shown which may be used instead of the plate 56, said plate 61 having a T-shaped slot 62 which takes the place of the slot 57 and the opening 59. The nail 53 is of course receivable in the wide front end of the slot 62 and the stud 54 is receivable in the narrow rear end of said slot 62. The configuration of this slot is also such that should the dowel pin be turned in the heel, the stud 54 may be received in an extremity of the wide front end of the slot 62, the formation of the slot then permitting driving of the nail 58 partly in the narrow rear end of the slot and partly in the wide front end thereof.

Fig. 14 discloses a reenforcing plate 63 which may be employed if desired, said plate having a straight-walled slot 64 to receive a flat attaching nail and being provided with a flange 65 on the front end of the neck 66.

The tool 6'7 in Fig. 16 is used for driving a dowel pin such as 21 into the heel. The pin 68 is receivable in the nail hole 22 and the socket 68 receives the stud 23, allowing the dowel pin to be driven without danger of injuring said stud or so battering the metal as to partly close said opening. The tool 67 of Fig. 17, with its fiat projection 68 and socket 69 is used in the same manner as the tool 67, but for driving a dowel pin such as 52, or even 48.

It will be seen that any form of construction is rather simple and inexpensive, may be therefore manufactured and marketed at small cost, and that any of the lifts may be quickly and easily applied, or removed when a new lift is to be substituted.

I claim:--

1. In a means for attaching a lift to a heel, a metal dowel pin embedded in the heel, said pin having a nail-receiving opening in its lower end and being provided on said end with a downwardly projecting stud, and a reenforcement embedded in the lift and apertured to receive said stud, said reenforcement being also apertured to receive an attaching nail to be driven into said nail-receiving opening.
