CUSHION -H EEL.

To all crhom z'tmay concern; a Be it known that we,Rom:nr SJQRAHAM and' Baritone l llloRsic, both citizens of the United States, the said GRAHAM residing in the city of New York, borough ofMan-- hattan, county and State of New York, and the said Morse residing inth'e city' of New York, borough of Brooklyn, county of and a soft or cushion material, thetwo inn-- terials beingso combined and related that the lower part of the heel is free to havea.

limited movementwith respect to the solid part and thecushion material...

The objects of the. invention are, to enable the heel-to be attached to the shoe ,by the ordianaryheeling machinery now'so extensively used'in shoe; factories; second,-

to minimizethe quant-iy of rubber, or other cushion materiahiconsistentwith the attain ment; of the purposes of; the invention; 4 third,toso securely attach the several parts reclude their accidental separation even siouldthe yieldable part of the heelas to become caught in thefact'ofwalking, and to provide for thefexpediti'ous andeconomr cal manufacture and attachment v article. i

The invention-'is' embodied in-ah eel onepart of which is composed of solid material so formed that'the top lift, or in reality such as rubber orrubber compound.

The umnufactnre of the heel, from a practical standpoint, an'd by existing machinery and in accordance with existing methods', involves the 'assen'il'ilage and attachment in:

-two sections and with a top lift, the latter consti'uiting a third section. The first section isattachrd-"as -ordinarily practised in the art; the second section isformed to carry out this invention, i. clby providin a 'bo'om layer composed. in part of soil material (leather) and in part. of rubber or cushion material, after which the 'c'omplete second section is attachedflhyfnailing Specification of Letters Patent. v "Application filed September 6, 1912". Serial No. 7 18398,

Patented May 6, 1913.

the solid part, including the half leather section, firmly to thefirstfsection, the nails being allowed to protrude, and 'finally the top lift (or bottom piece) is -positioned andattached by the protruding purts of the nails. v r

Inithe accompanying drawings, we havelllustrated different practical embodiments of the invention, but the Iconstruct-ions showh therein are to be understood .as illustrative, only, and not as defining the limits of the invention. c

Figure 1 is a bottom plan view of a heel constructed in accordance with this inventlon. Fig. 2 is avertical section taken longitudinal] through the heel illustrating one form oft e partlayer of cushionrnaterial.

Fig. 3 is a vertical longitudinalfsection illustrating another form of the layer of cushon material.

A designates a portion of ashoe" sole, and

BI-i'sf'the heel, This heel is composed of relatively hard material and, a, layer or sec- *tion of cushion material, The heel is at- -tached in. two or three sections, one of which is composed. of a; series] offlayerjs' 3 a." The- ,second section is composetho'f a part.'layer orlayers'of hardniaterial,ashb b and a part layer: of cushion ;material,; as; .0, and a lift id, whereas the third section .or top'lift'c'om As shown lnFig; :2, the second section embodies a'laver 'cofcushion material which is ,equali' in t ickness to t'wo layers 1) b ot leatheig the-two layers 1) b and the'rubber.

layer a being each equal in area to one half the area of the lift'a', althoughvthe relative proportions of the part a to the parts 6 7) composing-the .second section may be varied as desired. Furthermore, the rubber section c may be-' equal in thickness to a layer 6 so that only one layer 7) need be used, but i t-is preferred to, employ a cushion layers substantiallyequal in thickness to the two leather layers'b b. Inthe manufacture of the shoe, the first sectioncomposed ofthe layers ,a' a-are':fastened to-- gether and attached .tothe' sole at the heel portion-inthefordinary way and by existmg machineryq The second section consist-"- ing of the parts?) I) c (l are-assembled so that --a-'c11s h1on layer'o is imposed directly' againstthe'layerd and the pleces b are 1 positioned one upon the other and against a part of. the.layer d. The cushion layer 0 is attached in any suitable way as cement- I ing it to the layer (Z, whereas the layers]; 6 are attached to the layer 61 by nailing the parts together, the ends of the nails protruding in the usual method-of making heels by existing machinery.

It should be understood that the parts (I) b a d) composing the second section should be assemble as is the, second section of an ordinary heel. In the process of attaching the second section to the first section; said second section can he handled and applied with the same facility and advantage as the second sections, of ordinary heels.

The nails which fasten the first section of the shoe are indicated at e, and these-nails c are independent of the nails which attach the second section and the top-lift or bottom layer (1 to the first section.

In carryingthe present invention into practice, the second section and the top'liftare not nailed in the ordinary way, but on,

the contrary nails 7, g, 7). are employed, said nails being so positioned that the rear part of the layers d ll will be free or unattached.

I Nails are at the respect-ire sides ofthe heel, nails in are at the front edge thereof, whereas nails g are across thebreastof the heel, all the nails f, g, It being forwardly of the rear part of the heel which is to remain free and unattached. Nails h are driven through the first and second sections at the forward part thereof; nails f are at the respective sides of. the heel and are driventhrough the first and second sections, where as nails garedriven through the first and second sections forwardly of the rear part of the layers (2 (1, said nails 9 beingdriveltthrough the cushion layer 0, but in this connectionjt is to be noted that the nails f g 71 are not'driven home in attaching the second section to the first section the ends of the nails being allowed to protrude below layer Z so that the protruding ends of the nails are utilized in fastening the top lift or bottom layer (l to the heel.

It evident that the layers 1) b d of the second section will be attached solidly and firmly to the first sect-ion by the nails 7 g 71, but the rear part of lifts (Z at will be unatta'chcd so as to allow said rear parts of the two lifts to have a certain limited freedom of play, for the purpose of securing the desired cushion effect in connection with the layer c. The employment of a layer 0 which is equal to substantially one half the area of either of the lifts a d d provides for economy in the use of rubber required 'to produce composite heels of this invention,

Copies of this patent may be obtained for but at. the same time the important advanlarge is secured in the use of the sections Z) I) in connection with a half layer 0 of rubber. for the reason that the forward part of the heel may be nailed as firmly and solidly together as an ordinary leather heel, as a result of which the heel of this invention is capable of manufacture by existing heel machinery and in accordance with the well known methods, but at the same time the heel when attached is so secure and firm that it cannot become displaced accidentally, or. torn-off except by extremely rough usage.

In Fig. 2 the cushion layer has a straight forward edge and it is of uniform thickness so that the forward edge of the layer 0 abuts squarely against the straight reaiwcdges of layers 7) 7', but in the embodiment shown in Fig. 3 of the drawings, the cushion layer 0 is tapering, thus further reducing the quantity of'rubber required. Accordingly. the layers 6 if'are tapered at. their rezr edges in order that the tapering layer c may substantially overlap the tapering edges of the layers 1) 6*. Otherwise the heel is constructed and attaelwd in the manner aud" by the meanshereinbet'ure described f i In connection-with the'salieut features of economy of manufacture and security of attachmentof the heel,- it is desired to state that the rubber layer a or c 'is' fastened se curely in place at its forwardedge only by the row of nails 9' which are positionedat the breast of'the heel, and thus therubber layer cannot work loose or become detached from the heel. r v

Having thus fully described tlKillVtllilOll, what we claim as new, and desire to secure by Letters Patent is: i

A heel embodying an upper member composed of solid material, a layer composed partlyof non-yielding material audpart-ly of cushion mater'zl, both of said parts-being in the same horizontal plane. one or more lifts below the two part layer. and attaching means extending into the bottom lift or lifts andthe solid material of the two part lift andalso through the forward part of the cushion material, leaving free or mint- 3 tached that. part of the bottom lift or lifts below the cushion material.

In testimony-whereof we have signed our names to this specification in the presence of two subscribing witnesses.
