To aZZ whom it may concern:

Be it known that I, EDWARD S. SMITH, of

.Waterbury, in the county of New Haven and State of Connecticut, have invented a newIrnproveinent in HeelProtectors; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification, and represent, in Figure 1, a perspective view of the protector complete; Fig. 2, the blank from which theprotector is formed; Fig. 8, avertical central section through'the protector; Fig. 4, an under side View of the face of the heel; Fig. 5, a sectionot' theheel cutting through the several studs, and showing the connecting-bar; Figs. 6 and 7, modifications.

This invention relates to an improvement in the metallic device to be introduced in the heels ofindia-rubbcr boots, or heels made from any composition which is molded into theheel formed in aplastic state, so that the protector may be introduced in the process of molding,

particularly to that class of protectors which nected by a bar.

consistof several metal studs connected by a bar, the bar being embedded in the heel,while the studs project to the outer surface. Heretofore this class of protectors have been made from east rheiaheonsisting of several studs conln molding the heel great pressure is necessarily brought upon the composition, and this pressure brings irregular strain upon the bar andst-uds, and because of the non-elastic or non-yielding character of the metal the bars frequently break, causing a displacement of the studs, and consequently destroying the heels, so that a great-loss occurs in the employment of'such protectors.

The object of my invention is to construct a protector from wrought or sheet metal, as

in Fig. 2. Distant from each end of the strip equal to the circumference of the stud to be produced I cut-a slit 0r notch, a, from the outer edge-of the strip toward the opposite edge halfway across, inore or less, and from the bottom of each of these notches longitudinally, and preferably in the same line, I cut slits I), (see Fig. 2,) the two slits extending nearly to the center, but so as to leave the central portion, E, connected to the bar D, the part E being substantially halt'theividthot' the strip, more or less, while the two end portiors, F F, are of the full width of the strip. I now bend each end F into tubular form, as seen in Figs. 1 and 3, and preferably of larger diameter at the bar end than-at the opposite end, 'as indicated in Fig. 3. The central portion, E, I

bend from each end into tubular form, as also indicated in Figs. 1 and Thus bending the parts of the strip forms the tubular stud A at one end of the bar and the tubular stud C at the other end of the bar in full length, while the intermediate stud, B, is as much shorter than the studs A C as the depth of the bar D.

Prel'erablythe intermediate stud, B, is made of flLlStUlll-OfCOIlQ shape, as shown. The axis of the several'studs should be substantially parallel with the plane of the bar. a

The protector is introduced in the process of molding the heel, so that the composition of the heel surrounds the bar D and li.ls the respective studs, as seen in Fig. 5. The enlbedding of the bar within the heel, leaving the ends of the studs exposed upon the face of the that I do not claim, broadly, a metal heel-pro- 1. Theherein-describe'dheel protectormade I tubular studs will project beyond the edge of the bar, the intermediate studs, also bent into tubular shape, but shorter than the studs at the ends of the bar, the axis of the several studs being at substantially rightangles to the I5 bar, substantially as specified.

EDWARD S. SMITH.
