HEEL OF BOOTS AND SHOE'S,

' Application filed May 25,1923; Serial No. e41,4a7.

To all whom it may concern:

Be it known that I, J osnrrr EDWIN MARK- HAM GOOKE, a British subject, residing at Stafford, England, have invented certain 5 new and useful Improvements in Heels'of B 138 and Shoes, of which the followingis a specification.

" The present invention relates to heels for boots or shoes and more particularlyto. an

improved-type of heel which is capable of attachment either in' the manufacture or the repair of a boot or shoe. 1

The object of the present invention is to provide a boot-orshoe' heel which shall be superior to existing types of. heel from the standpoint of weight, wearing qualities, -fa-- cility ofattachment and cost of manufacw ture. This. object is attained through the employment of a heel body or core consisting of a series of ply-wood lifts built in the general shape of .a heel and completely surrounded about the sides andbottom or tread by an integral covering of rubber or'similar. vulcanizable material molded 'thereabout and adhering thereto. The upper face of the core is substantially coincident with the upper or attaching face of the finished heel 5 and in effect constitutesthe major portion ,of the attaching face of the heel. Under certain conditions of manufacture, the outer covering may be turned inwardly over the attaching face in the form of a relatively thin or skim coating of rubber or vulcanizable material. a

Thisform of heel is particularly adapted for use as a whole heel attached directly to the sole of av'boot or shoe in place of the usual heel consisting of leather, leatherboard or wooden lifts either with orwithout a tread lift of resilient materi'alfsuch as rubber. The present heel is lighter than whole heels made either entirely of rubber or of rubber and leather or leather substitutes and in addition has the very 'dis tinct advantage that'it is completedin the molding Operation and does not require any "substantial finishing operation after appli cation to the boot or shoe. I

. The heel maybe readily attached to the sole of a. boot or shoe by'mea'ns of.nails orfastenings driven into the wooden core or body of the heel, the latter serving to hold'the nails and prevent loosening of'the heel. In th illustrated embodiment 5f the invention, the nails are driven into the plywood body from the inside of the shoe, al-

. though it isevident that this method of attachment might be modified if so desired. The employment of the ply-Wood core of substantial area avoids the necessity of accurately locating the attaching nails or fas 'tenings either during the manufacture of thebootor shoeor its repair." Furthermore, the employment ofa built up core or body of ply-wood serves to hold the nails or fas- -'ten1ngs securely without liability of-cracking Or splitting the core through penetration of the nails.

In the accompanying drawingsillustrating the preferred form of the invention Fig. 1 is a transverse section of a heel consisting of a body built up of ply-wood lifts and provided with a resilient cover, the heel being shown as attached to a sole-by nails driven 'therethrough; Fi tion of the heel s own in Fig. 1 before attachment to a sole; Fig. 3 isa top plan view of the heel shown in Figs.- 1 and 2; and Fig. 4 is a detail showing a section of the heel 2 is a longitudinal secand illustrating the stepping of the lifts.'-

, The heel shown in the illustrated embodi-' *ment of the invention comprises a: wooden body or core A having approximately the contour of the finished heel with a concave upperor attaching face. The central core is formed of a series of ply-wood lifts a, having the ain crossed, which are secured 'to one anot being indicated for this purpose. The sepa-. rate ply-wood lifts may be stepped, as shown in Fig. .4, to obviate any possibility of the rubber or vulcanizahle cover becoming separated from the body of the heel. Stepping of the plies tends to. facilitate thepenetration of rubber thercbetween during the-vulcanizing operation and aidsin bonding the cover to core A is completely surrounded at the sides and bottom or tread face by a "casing or cover of riibber or other vulcanizable marteor in a suitable manner, nails e -theiwoodenbody. -Thebody or rial molded and vulcanized'to the body and forming the tread portion B of the heel.

h b ck an ide f he h portion of the area of the heel inside the K has the general contour of the heel and is concave convex in section. The finished heel is provided with a flat tread face, as indicated in Figs. 1 and 2 and the shape and location of the core within the finished heel is such that the tread portion is thicker throughout the area of greatest wear, as indicated at the rearportion h and about the outer edges of the heel. 7

When applied to a'boot or shoe, the upper face of the heel body or core is placed directly in contact with the attaching face of the shoe and secured thereto by nails or 'fastenings 0 passing through the core and 15- l ing heel body or core in direct contact with the shoe sole i'The. location of the unyieldthe attaching face of the shoe provides a 'method of firmly attaching the heel to the shoe and minimizes the liability of-the heel working loose after application. It should be"understood,in this connection that the presence of a relatively thin or skim coat- .ing of rubber or vulcanizable material extending inwardly over a portion of the atmaterially lighter t taching face of the wooden body, as shown in Fig. 4, will not interfere with the function or mode of operation of the heel body as described. I

According to the resent invention, a heel han other heels adapted for the same general purpose has beenproduced without impairing any of the desirable characteristics of the heel. Furthermore the heel is well adapted to existing methods of manufacture and permits dispensing with certain operations essential to the manufacture and attachment of other types of heel.

' It is obvious that the invention herein.

shown, described and claimed may be applied to various kinds of heels, either whole heels or half heels or heel lifts and where reference. is made in the specification and claims to heels, it is intended to include perils of various kinds, halfheels and heel The use of the term rubber. throughout the specification. and claims is intended to cover not only rubber and rubber compounds but the use of similar or equivalent vulcanizable gums andcompounds which may be molded and vulcanized in a similar manner to rubber and when so molded and vulcanized will have the same general characteristics of resiliency and wear.

Having thus described the iiwention, what is claimed is: i

1. A heel for boots or shoes having a body portion extending throughout the major margin and consisting of a plurality of 'plies of wood connected together, and anintegral covering of rubber completely surrounding the sides and bottom of the body portion, the cover being molded in the form of a heel and bonded to the ply-wood body portion and extending'partially across the top of the body portion, the cover being molded in the form of a heel and bonded to the ply-wood body during the vulcanizing operat1on.

3. A heel for boots and shoes having an outer rubber cover molded and vulcanized in the contour of a heel, and a relatively unyielding heel shaped core consisting of a plurality of connected thinplies of material unaffected by the vulcanizing operation embedded in the outercover and bonded thereto during the vulcanizing operation.

4. A heel for boots or shoes having a body portion consisting of a series of plies of wood with the grain crossed and united to one another to provide a heel shaped member with uneven side portions, and an outer covering ofrubber molded about the sides and bottom of the body and bonded thereto during the vulcanizing operation to fotm a finished heel. t I 5. A heel for boots or shoes havingan outer cover of rubber molded in the con-- tour of a heel, and a body of thin plies of wood embedded in the outer cover and bonded there-to during the vulcanizing oper ation.

6. A heel for boots or shoes having an outer molded cover of rubber with a flat tread face and the contour. of a heel, and

a bodyof thin plies of wood stepped with relation to one another and'embedded in the outer cover. and bonded thereto, the upper face of the body constit'utingaportion of the attaching face of the heel.

7. A heel for boots or shoes having an; outer molded cover of rubber with a flat tread face and the contour of a heel, and

abody of thin plies of wood stepped with relation toone another and embedded in the outer cover and bonded thereto.

In testimony whereof I- have aflixed my signature.
