1935- A. G. EICHHORN SHOE CONSTRUCTION Filed April 8, 1952 Patented I 10, 1935 UNITED STATES PATENT OFFICE ,SHOE oous'rnuc'rion August G. Eichhorn, St. Louis, Mo., assignor, bymesne assignments, to PermaCorporatlon, Chicago, 111., a corporation of Illinois Application April 8, 1932, Serial No. 603,995 16 Claims. 36 24.

This invention relates to foot apparel manufacture and more particularly to 'the heel construction thereof.

Foot apparel, as now manufactured, has the 5 heel secured to the heel seat of the shoe by means of nails, by means of screws and even by bolts,

and in either instance the breakage of wooden heels, such as are used on womens shoes, is considerable, it slows up production and results in unnecessary expense to this operation in themanufacture of shoes. q

It is therefore one of the primary objects of this invention to providenovel means fixed to the heel seat of a shoe and provided with means receivable in recesses formed in the base of the vheel, and also, the provision of means carried by the heel and engaging the means receivable in the heel recesses for securely holding the heel to the heel seatof the shoe by drawing the baseof the heel seat intotight contact with the heel seat of the shoe and holding it there. 7

Another salient object of the invention is to' provide novel means for detachably securing a heel to the heel seat of a shoe.

A further object of the invention is to' provide the heel seat of foot apparel, such as shoes, with a plate by means of suitable fasteng ing devices and with portions of the plate extending into heel recesses formed in the base ofthe [3- heel where such plate portions are fastened by independent means for securely locking the. heel 'to the heel seat of the shoe.

A further object of the invention is generally to improve the heel construction of foot aprel. i A still further object ofthe invention isthe provision ofa heel construction for shoes, which possesses advantages in point of simplicity,- eliminatesbreakage of wooden heels in the application thereof to the heel seats of shoes, and, at the same time proves itself comparatively inexpensive in the cost of manufacture and especially so in the application of the heel to the shoe.

With the above and other objects in view,'the invention consists in the novel application of heels to shoes, construction, arrangements, combinations and formation of parts, as will be hereinafter more fully described, claimed and illusdo in the accompanying drawing, in which "drawing:

'- Fig'. 11s a view of the heel seat portion of a seat portion of a shoewith the heel attaching plate fixed thereto.

Fig. 3 is a view illustrating the manner 'of securing a heel to the heel seat of a shoe and em-. bodies the features of this invention. 5

Fig. 4 is a top plan view of a shoe heel illustrating the recesses formed in the base thereof.

Fig. 5 is a side elevation of the heel attaching plate.

Fig. 6 is a front elevation of the heel attach- 1o ing plate, with a portion thereof broken away.

While this invention relates generally to foot apparel, and particularly to an improved heel construction for shoes, the same has been illustrated as including a wooden heel for ladies l5 shoes, but it is to be understood that the same is applicable to men's children's shoes, as well.

-In the drawing, A designates a part of the heel portion of a shoe, and includes the outsole B, the insole C, and the heel seat. of the shoe which is 0 formed by the trimmed heel portion D ofthe outsole 3- to reduce its thickness and the turned under portions of the upper, the counter and the lining of the shoe, which is designated generally as E, and, which is like heel seats in the present 2 shoe construction, excepting that the heel portion of the outsole in this case fills the entire heel seat cavity of the shoe.

In carrying out the aim of the present inven--, tion, a suitable plate I is employed, preferably metallic. The plate I is applied to the trimmed heel portion D, of the outsole B and to the marginal edge of the turned under edge portion E of the heel seat of the shoe. The plate I has the general outline of the heel seat of the shoe and 35 shaped to the contour thereof by being longitudinally, and transversely curved, as shown in Figs.

5 and 6, and it is secured to the heel seat of the shoe by means of suitable fastening devices 2,

which fastening devices, as shown, are integral nated 3 and l are formed on the plate I and (ll-F rected downwardly therefrom at approximately a right angle thereto. The keepers orears I and I are spaced a. suitable distance apart from each other and each is provided with a lock pin opening l..'1'heapertur edkeepersorears3and4 The usual base or heel seat surface I of the heel 6 is provided with a plurality of transversely disposed narrow slotted relatively shallow recesses designated 8 and 9, and-these recesses enter the heel a distance equal, or better than the lengths of the keepers 3 and 4, respectively, of the plate I. The recesses 8 and 9 of the heel 8 are of such dimensions as to cause the keepers 3 and l to engage the walls thereof when the heel 6 is applied to the heel seat of the shoe, as clearly shown in Fig. 3.

The heel 8 is provided with a bore or opening of uniform dimension throughout its length II, which opening is directed into the heel from the breast ii thereof a short distance below the heel seat surface 1 thereof. The opening II is so positioned that when the heel is applied with the desired pressure to the heel seat of the shoe. that it will register with the openings I in the keepers or ears 3 and l, and at which time a suitable lock-pin I2 is forced into the heel opening ii so as to pass through and'fricticmally engage in the openings 5 of the plate ears I and 9 for holding the heel in a locked position on the heel seat of the shoe and against displacement thereon.

When the heeli is applied, in the manner shown, to the heel seat of the shoe, the heel is securely held to the'heel seat of the shoe. If desired, glue may also be employed when attaching the heel to the shoe heel seat. This is desirable when the heel is not to be detachable. When it is desired to have the heel readily detachable from the heel seat of the shoe, the breast ll of the heel S adjacent the outerend of the lock-pin opening I0 is enlarged, or recessed, as at ll so that the outer end of the lock-pin I! may be easily grasped by means of a suitable extracting tool, as is manifest, for withdrawing the lock-pin I! from the opening I. and the openings 5 of the keepers or ears I andl.

When the heel 6 has been applied, as described, to the heel seat of the shoe, the usual breast leaf M, which is a part split from the outsole B is applied to the breast Ii of the heel 6, in the usual manner, and it conceals the outer end of the lock-pin l2 and the breast recess l3 from view. If the shoe heel is tobe detached. for

any reason, the breast leaf I 4 will first have to be removed fromthe breast of the heel. as is manifest.

Due to the fact that the trimmed heel portion of-the outsole extends beyond the juncture of the shank therewith and fills the heel seat cavity within the edge of the turned under upper, counter and lining portions of the shoe, weakness at the juncture of the heel portion of the outsole with the shank portion thereof is obviated, and the improved shoe is greatly strengthened at this point where ladies shoes, in particular are generally rather weak, and, therefore the tendency of the outsoleto be broken at the front edge of the heel is eliminated. v The heel'6 can be applied to the heel seat of a shoe by hand, or it can be applied thereto by a machine, the latter where increased production aoaaevi is required and. at less cost than .by hand and less than applying wood heels to ladies shoes by the present method.

The many advantages of the hereindescribed invention will readily suggest themselves to those 5 skilled in the art to which it appertains.
