i uNITEnjs s P TENT OFFICE} GEORGE 1v. DAMON, or w rm; OHIO, 'nssreivon TO THE LonAINnUBBEn HEEL GOM- Pentagon Lonanmorno, A oonronnrron oronro;

To all'jwltomitmay concern) I Be it known that I, Gnonen N. DAMon, .a'citizen'of the;UnitedStates, residing at 360 VVashin'gton avenue, Lorain, in the county of Lorain and State of Ohio, liaveinvented'certain new and usefuhIm'provements in Rubber Heelsand Inserts Therefor, of which the following isa specification.

This invention relates' to resilient'heels for shoes or other articles "of footwear.

The object of-the invention is to provide an improved heel .jofjcushion form designed tosoften the blow of impact with the7'pavement and which is equippedwith an improved wear resisting member or element of simple form which can be mad'e'and embedded in the heeljby simple operations-and at low cost, and which member is firmly anchored and not liable to pull out of place and which greatly increases the life ofthe heel. A further .objectfof the invention is to provide a wear resisting member or ele-- ment of specialfform-and configuration for the purposes beforestated.

Further objects of the invention are in 7 part obvious and i11 partwillappear more present invention is in large measurean im-" in detail hereinafter.

The. invention comprises the construction parts hereinafter de and arrangement of scribed and clalmed.

' rubber or other suitable resilient material having a bottom tread portion 2 and an comprises the body portion 1 formed of upper portion 3 designed for application tothe shoe heel. This upper portion may be of any suitable form and is shown as provided with a raised beveled marginal sealing portion 4 whichis compressed when the heel is applied and seals the edge point. The heel is secured by nails or other securing i 5 Specification of Letters Patent.

extending pr ection or extension? of any f desired shape in'plan view above which is a generally similarly shaped recess orcavity 8 in'the upper portion of the heel. arrangement provides a sealed top chamber This between the rubber heel and the heel lift above it and formsa pneumatic cushion to soften'the blow of impact with the paveme'nt. Ordinarily this cushion would be subjected toan increased wearing effect due toits projection from the bottom of theheel but undue wear is prevented by a wear resisting element or member 9 of special form whichis embedded or inserted in the heel body during its manufacture. This member is'shown in'detail in Figs. 4 and 5. It

comprises a wear, receiving body portion '10 connectedby a short offset neck 11 to an anchor portion 12.. The body and anchor "portions, speaking generally, are both of oval or oblong form and may be'ofthesame size and general shape if desired. As illusportions are offset by the neck 11 so that they lie in different planes. When the inat 13, some or all ofwhichmay become filled with the resilient heel material to further anchorthe parts and prevent twisting. Two

*trated in Fig. 1 the body portion is slightly larger than the anchor portion and the two of these recesses in the body portion are utilized for locating the wear resisting memher in the mold while forming the heel, said recesses being caused to register with and receive small pins in the mold as is usual. These pins therefore leave the small holes 14: in the resilient material, the hole 15 being formed by a third pin which supports the.

anchor portion above the mold bottom so the rubber will flow beneath it.

The peculiar formof the wear resisting member-enables it to be cheaply manufactured and built into the heel. For example it may be made of metal and cut or punched i from a metal sheet. Fig. 6 illustrates one arrelation to avoid waste of metal. The possibility of thus cheaply forming this part makes it desirable in some cases to make the two portions of the wear resisting member of the same. size and shape. H

As shown in Fig. lithe anchor portion of the memberf) at each end extends beyond the boundaries of the projection from the heel bottom. This 'arrangementis not necessary as the member 9 will be made in several sizes tor di'lterent heels and may be: proportioned in any manner with regard to the, size or the heel recess and projection. For the same purpose, as shown in Fig. 2, the body portion of .the wear-resisting member 9 may e.\ tend radially outwardlytoward the edge of the heel beyond theouter edge of the recess or cavity 8, so that both'the body and the anchor portions of themetal insert. are in part backed by a solid part of the rubber above them. As a consequence the metal insert is not pushed upwardly whenthe heel strikes the ground but is held down to receive the wearing elteot. At the same time some cushioning eilec-t is retained; However when the latter arrangement is used a part of the'blow of impact is: imparted to the solid heel body which tends'to slightly reduce the cushioning efi'ectand to some extent increases the life of the heel.

with the objectionable click which metal a parts solidly embedded in; a heel produceon impact with the pavement, and the entire construction provides a durable heel at low What I claim is: l. .Aresilient heel having a body portion provided withanupper cushioning chamber and a wear resisting member embedded in said body portion below said chamber and provided with body and anchor portionslying in; difierent planes, said member extending horizontally beyond the edges of said chambenv v A resilient heel, comprising a body portion provided with a downwardly extendmg projection and above the same with a cushioning recess, and an 1 insert h in a body portion exposed atthe lower s rface r said projection and an anchor portion-above and to one side thereof, said insertbovdy porof said recess.
