GUSHION-HEEL To all 'whom t may concern.'

and has particular reference to steel rein.

forcement molded in on elastic heels such as rubber cushion heels and .the like. The object of the invention is to overcome difficulties heretofore experienced in the various attempts to metalshoe th-at portion of the cushion heel which is battered down in advance of wear on remaining portions, and.

the invention consists in the improved metal shod cushion heel, in an improved heel plate molded in with its lugs or fasteners embedded so close to the surface of the rubber, that the resiliency of cushion heel is not lessened perceptibly, and in the combination.,

construction and arrangement of parts, all

as hereinafter more particularly pointed out in detail description and in the appended claims.

In the drawing- Figure 1 is a perspective bottom view of a cushion heel fortified with the present improvement. i

Fig. 2 is ran enlarged edge and top perspective view of they heel, partly broken away and partly in section to disclose the incorporation of the plate parts as substantially an integral part of'the body of the heel.

Fig. 3 is a perspective view of the heel plate itself.

Fig. 4 is a section taken substantially on line 4-4 of Fig. 2.

Fig. 5 is an enlarged section taken substantially on line 5*-5 of Fig. 1.

Fig. 6 is a section taken substantially on v Specication of Letters IatenNt.

tute substantially inte ral portions thereof. flhe usual method of 1s to employ screws or nails, which act as rigld posts interposed against resiliency movements in the shod portions, or integral spurs which work loose and cause wearers a great deal of annoyance. Hence while to the uninitiated the problem of fastening these plates to rubber heels, has appeared easy of astening such a platesolution, a large variety of forms ofA devices have failed to operate successfully 'or acceptablfy owing to the exceptional strains imposed upon that portion or corner of the heel which receives nearly all of the blows of violen't first impact against road or pavement.

In the present improvement the plate 4 and its holding means are cast or molded into the heel7 orincorporated as a part of the body material. To this end the plate is provided with integral end lugs in the form `of an upwardly bent portion 5 and a horizontally bent portion 6 extending over the body of the plate 4 at one end, and similar vertical and horizontal portions 7 and 8, respectively, at the opposite end. rAt the middle of the plate, but arranged at right an les to the-lugs named is a similar elbow ug composed of parts 9 and 10, as shown very plainly in Figs. 2 and 3. These figures also show that the holding lugs are arranged on and near the rear edge of the plate 4, which rear edge is designated by the numeral 11, while the front, or exposed, edge is designatedas 12.. As the latter edge receives the most violent part of the blows of impact it is relieved of fastening means which would tend to work loose, and by being removed to the rearedge the fastening lugs will be so embedded in the body of the rubber, or other material used for the heel, that the tearing away of the shod portion of the heel is oblviated. The lug portion 9 interposes a broad face surface agalnst movement of the plate rearwardly with respect to the shoe or heel, or toward what has been'termed the front edge 12 while the broad faces oppose move-v ment at right angles to the facing of lug 9. The portions 5V and 7 project beyond the ends of the body portion 4 and present their edges,I removed, as shown, a substantial dis-v tance from the vertical outer surface of the heel. This construction also enables meto employ heel plate metal of the necessary degree of temper, it being' well known that the wearjon the metal of an, ordinary heel platel end of the plate and the consequent .loss of its holdin lug.

On rub r heels metal plates also serve. to produce a slight click, suicient to give another warning of the approach of a pedestrian from the rear 4to obviate the unpleasant surprises that wearers of rubber heels often innocently occasion. The deflection from parallelism with the plate 4,1of the holding portions 6, lO-and 8, is illustrated in connec# the direction of strains tendin to release the plate 4 fromthe heel makes t em powerfully effective even if lmade so thin or weak that they would be useless if arrangedl parallel to sa1d direction, or at right angles to the plate 4 in accordance with usual constructions.

i I {aving thus described my invention, I claim as new and desire to secure by LettersPatent e 1. The combination with a heel, of a plate extendmg to a fractional rtion of the outer edge of said heel, said" plate having integral angle lugs.' that roject u wardly tion with the. part. 10 in Fig. 7, the free end\\ from and then horizontal y over t e body of which is slightly bent downward in obedience to the compression and expansion movements in the body of the heel 3, which movements, of course .aref greatest at the extreme rear o f the heel. It will be seen that at this point the chief Work of the heel asa so'ck absorber is accomplished, and that in t e resent inventionl the fastening means for t e plate 4 interpose no resistance whatever to `the compression of the cushion. However since the plate is molded in close l to the tread or wear surface of the heel the resilienc is not materially interfered with f even if t e horizontal lugs are comparatively bf the plate from an inneredge thereof and arl'etpaced away from the outer edge of said p a 2. The combination with a rubber heel, of a plate of metal embedded in the outer corner of the heel and having holding means which are molded into the heel and consist of integral angle lugs which project upwardly from the inner face of saidplate and then project horizontally over, parallel to and spaced apart from said face and'from the outer edge of heel and plates In testimony whereof I have hereunto signed my name.
