As herein illustrated, the corner stiffening or tensioning plates are substantially flat when theV heel is allowed to assume its natural shape, becoming somewhat curved when the heel is flattened under the attaching pressure and thereby producing a substantial amount of tensionv which causes the corners and breast edge of the rubber heel to press tightly against the base and permanently maintains .a close oint.

While the attached drawings show a rubber halt` heel, it shouldbe understood that the invention is equally applicable to whole heels and top liitts; and it should further be understood thatfwhereverthe term l rubber is used to refer to the heel it is to be construed to cover any rubber or other composition suitable forinakiiig cushion or resilient heels. f

Further fea-tures and advantages ot the invention. will; be better understood tro'm reading the following detailed description ot one embodiment thereof, in connection with the accompanying drawings, in which Fig. 1 is a view Vofthe tread tace of a rubber heel embodying the invention, a portion of the material being broken away to reveal lil Y ing machine; and

Vivi) Fig.V 5 is a. sectional view on the same line as Fig. 2 showin@ the heel attached to a shoe. y Y

ReferringA now to the drawings in detail,

` indicates the heel which may be vmade of rubber or any of the usual compositions employed in making cushion heels. Holes 12,`

through which theY attaching nails are to be driven, may beinolded in the tread face of the heel, certain oiithese holes beingsurrounded. by washers 14- and others left blank to permit the practice of the improved inethodof attaching a rubber heel and a base aV single nailing, which vis described f and claimed in my copending application, Serial blo. 487,314 tiled July25, 1921.V

Embedded in the breast corners of the heel are two separated, symmetrically varranged plates 16, arranged cross'wise of the heel approximately parallel to its breast edge andr 'having angularly disposed points 18 which project into the breast corners ot the heel. 'lhese plates may be made otany suitable material such, for example, as flexible spring steel and, as shown.,are` flat, although this is Vnot essential. Eachot'the plates l16 is provided with two holes 20, ofnsutlicient size to permit the passage ot the shank of a heel ported upon the pins in the same manner as washers while the heel is being made. is shown in Fig. 2, the tread tace of the heel is convex around the edge at 22 and the inner face is correspondingly concave, as shown atV 24:, when the heel is in its normal shape.

Fig. 5 shows the heel attached to a shoe 26; 28 indicating the heel'seat portion of the shoe sole and 36v indicating a base/section, such as is commonly employed with rubber halt heels.l Then thus attached the heel is flattened out and secured by headed nails 32 which are clinched on the inside of the shoe. As an incident to the tlattening out ot the heel the points 18 of the plates 16 are curved outwardly, as shown c'learly in Fig. 5 and, in this condition exert a constant tension, tending to press the cornersot the rubber heel tightly against the base. Although it is not essential tor the purposesv ot the invention that the attaching nails pass through the plates 16, l believe that the most eliective and permanent result is secured by passing the nails through the plates, as illustrated.

lnasinuch as the location ot the plates'l is Confined to the breast portion only oit the heel where resiliency is of small importance, it is not essential that the plates be separate but, in the higher development of the invention, it is preferable that they be separate and independent in order to minimize any tendency toward rigidity in the heel.

A cushion heel having nail head engagimr Vwashers at certain nailing locations and stiilening members of larger area andy a; shape different from that of the ywashers at ly herein but is claimed in my PatentNo. 1,586,556, granteddune 1, 1926 upon an application, Serial No. 607,077, tiled December 15, 1922, as a continuationof the present ap'- plication` as to all subject-matter whchis common to both applications.

` Having described the invention,what is claimed as new and desired to be secured by vLetters Patent is the rear or" the heel.

2. A cushion heel having a'pair oit narrow,

separated tensioning members theV body poi'- A tions of which lie aproXimately parallel to the breast edge of the heel, each of said Vother nailing locations is not claimed broadmembers having a projection shorter thany the body portion extending angularly therefrom into a breast corner'of the heel and be- 'ing devoid of any projections extending tovvard the rear of the heel.

3. A cushion heel ofnormally concavo-l convex cross section transversely, having embedded in the `concave-convexl part a transversely disposed normally flat, iiexiblc plate. f Y 4g A cushion heel of normally concavoconvex cross section transversely,` having embedded in the concavo-convex part a transversely disposed normally lflat;v Avrresilient plate. f

5. A cushion heel having across its breast portion only a plurality of separate and ine y the heel'. Y y
