HEEL

Filed DeC. 3, 1957 Patented June 13, 1939 HEEL Lewis J. Bazzoni, Swampscott, Mass., assignor to United Shoe Machinery Corporation, Paterson, N. .1., a corporation of New Jersey Application December 3, 1937, Serial No. 177,946

2 Claims.

This invention relates to the manufacture of shoes and is illustrated as embodied in a wood heel which may be quickly and effectively applied to a shoe of the type disclosed in United States 5 Letters Patent No. 2,125,328, granted August 2,

1938, on an application led in my name, of which the present application is a continuation in part.

The unattached sole of the shoe disclosed in said application is split by a saw to form a heelbreast covering ap and a heel-breast receiving shoulder which is of uniform height and extends from one side of the sole to the other. There is also disclosed in said application a Louis heel having a forwardly projecting lip the front end of which is approximately complementa] to the heel-breast receiving shoulder of the above sole attached to the shoe. The lip has excess length in order that the operator may grind from its forward end a suitable amount of material to insure that the lips of heels positioned up-on said shoes shall snugly engage said heel-b-reast receiving shoulders. It is desirable that the shape of the front end of the lip remain unchanged when material is removed from the same. Otherwise the operator would have to rasp` the forward end of the heel breast preparatory to laying the .ap in order to cause the covered breast of the heel to merge attractively with the shank portion of the sole of the shoe.

In order to provide for quickly and effectively attaching heels of the type above described to shoes, the front portion of the projecting lipof the heel, in accordance with a feature of this invention, is of uniform thickness throughout its width for a short distance rearward of its front end, the attaching face of the heel being provided with a recess shaped to receive the heel-seat tab of the attached sole of a shoe and the remaining and major portion of the attaching face of the heel lying approximately in the plane of the rim of the heel. When material is removed from the lip the forward end of which is of a thickness equal to the height of the heel-breast receiving shoulder of the above-mentioned sole, its front end remains complementa] to the heel-breast receiving shoulder and consequently a smooth joint over which the heel-breast covering flap may be laid is formed between the sole and the lip of the heel without having to rasp the forward end of the heel breast as above described.

The various features of the invention will be understood and appreciated from the following detailed description read in connection with the accompanying drawing, in which Fig. 1 is a perspective view of the rear end of a prefitted sole;

Fig. 2 is a perspective view of the rear end of a shoe to which the sole of Fig. 1 has been attached;

Fig. 3 is a plan View of the shoe of Fig. 2, the base portion of the flap of which has been broken away;

terial from said lip; and

Fig. 8 is a side view, partly in section, of the heel end of the finished shoe.

The illustrated heel 2Q to which a cover 2| has been applied is described with reference to its attachment to a shoe 22, the sole 24 (Fig. 1) of which is fitted for the reception of the heel prior to its attachment to the shoe upper.

The heel end of the un'attached sole 24 is split by the machine disclosed in United States Letters Patent 2 No. 2,107,281, granted February 8, 1938, on an application led in my name, to form a heelbreast covering flap 26 and a heel-breast receiving shoulder 28 of uniform height extending from one side of the sole to the other. After the heelseat portion 3B (Fig. 1) of the sole has been reduced to form a heel-seat tab 32, the sole is permanently attached to the shoe upper (Fig. 2)

In order to form between the projecting lip 34 of the attached heel 20 and the shank portion 36 (Fig. 8) of the sole of the shoe a smooth joint over which the flap 26 is laid, the front end 38 (Fig. 5) of the lip is substantially complemental to the heel-breast receiving shoulder 28 (Fig. 2) which is bowed rearward slightly (Fig. 3) due to the sole being eXed transversely in accordance with the curve of the last 39.

It is desirable that when the heel 20 is positioned upon the shoe 22 with its rear end 40 (Fig. 7) in alinement with the rear end 42 of the counter portion of the shoe, the lip 34 of the heel shall snugly engage the heel-breast receiving shoulder 28. Because of inaccuracies in sole laying and slight variations in the lengths of heels of the same size, it frequently happens that when the front end 33 of the lip of the heel 20 is in register with the heel-breast receiving shoulder y alined with the rear end 42 of the counter portion of the shoe upper.

To form upon the attached sole another heel-breast receiving shoulder which is located forward of theV existing shoulder in order that the heel may be moved forward to its proper position upon the shoe, is a time consuming operation. Furthermore, when the heel-breast receiving shoulder is located too far forward the lip of the heel positioned upon the shoe is not in engagement with Vsaid shoulder and consequently the gap between the shoulder andthe lip is Visible from opposite sides of the finished shoe and a slight depression is usually formed in the kportion ofthe flap overlying said gap.

yIn order to insure that the heel 2U may be correctly positioned Yupon the shoe with the front end 38 of its lip 34 in engagement with the heelbreast receiving shoulder 28, the lip 34 is of slightly excess length. When the heel has been placed upon the heel seat (Fig. 2) of the shoe with the front end 32 of its lip 34 in engagement with the heel-breast receiving shoulder'l28 the operator can tell ata glance the approximate amount of material that must be removed from the lip in order that the heel shall seat correctly v 48. An experienced operator can Ytell by the feel when the proper amount of material has been removedY from the lip 34. It is desirable thatthe Vfront end 38 of the projecting lip of thercovered heel shall remain.lv complemental to the heelbreastreceiving shoulder 28 as material is removed from the lip thereby insuring the formation of a smooth breast joint between the heel and the shank portion 36 of the sole of the shoe without having to rasp material from the upper end of the heel breast as above described.

With the above considerations in view the front portion of the lipV 34 of the heel is of uniform thickness throughout its width. for a short distance rearward of its front end 38. The front end 38 of the lip of the heel is curved transversely as shown in Fig. 5 in accordance with the transverse curvature of the heel-breast receiving shoulder 28 (Fig. 3) and may be described as having its upper and lower faces 50 (Fig. 5), 52

(Fig. 6), centered about a common axisV which lies in the central heightwise plane 53 (Fig. 5)

of the heel and which extends generally lengthwise of the heel and is arranged above the atsole (Fig. 3) after its attachment to the shoe, Y

the front end 38 of the lip 34 is correspondingly incurved as illustrated in Fig. 5.

The forward end of the attaching face of the heel is provided with a cavity 54 in which the heel-seat tab fits, the remaining and major portion 56 of the attaching face of the heel lying in the plane of the rim of said attaching face and engaging the substantially flat overlasted counter portion of the shoe upper.

After interposing a suitable adhesive between the heel-seat portion 44 (Fig. 2) ofthe shoe 22 and the heel 20, the heel is temporarily attached to the shoe and the iiap 2S is applied to the breast of the heel by the machine disclosed in United States Letters Patent No. 2,123,926, granted July 19, 1938, on an application filed in my name.

Having described the invention, what I- claim as new and desire to secure by Letters Patent of the United States is: K

l. A Louis heel the forward portion of the attaching face of which is provided with a recess shaped to receive aheel-seat tab of an attached sole of a shoe and the remaining and major portion ofthe attaching face of which lies approximately in the plane of the rim of said face, said heel having a forwardly projecting lipV the front end of which is of uniform thickness throughout its width for a short distance rearward of its front end.

2. A Louis heel having a forwardly projecting lip the front end of which is concave and is delined by parallel upper and lower edges, the forward end of the attaching face of the heel being provided with a recess which terminates at said upper edge and is shaped and arranged to receive a heel-seat tab of an attached sole of a Shoe, the remaining portion of said attaching face being arranged approximately in the plane of the rim of the attaching face of the heel.
