WEAR-RESISTING MEMBER.

To all whom it may concern:

Be itknown that I, ANDREW Barons, a citizen of the United States, and resident of Fairhaven, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in lVear- Resisting Members, of which the following is a specification.

This invention relates to metal wear-resisting members which are commonly driven into heels and soles.

The particular style of wear-resisting member to which the present invention relates is that consisting of a strip or plate of.

sheet metal which is driven edgewise into the leather.

The object of the invention is to form the wear-resisting member so that it will become interlocked in the leather when it is driven The invention consists in providing separate and distinct beveled portions on the edge which is driven foremost into the leather so that, by the action of the beveled faces on the leather, those portions will be deflected from their normal paths with relation to other portions of the plate. The deflection of the beveled portions causes the plate to change its shape while being driven so that it cannot work loose and become detached from the leather after having been driven. The initial shape of the plate when formed ready for insertion is capable of variation, but whatever shape is adopted should prevail uniformly throughout the length of the device so that the entrance which is made by the foremost edge when the device is driven into the leather will have precisely the same shape as the upper edge of the device.

Of the accompanying drawings which illustrateone form of a wear-resisting member embodying the present invention, Figure 1 represents a perspective vie-w. Fig. 2 represents in solid lines an elevation of the device in its original form, and in dotted lines a similar elevation of the device in the form which is the result of being driven. Fig. 3 represents an elevation of that edge of the device which is driven foremost into the work. Fig. a represents an edge elevation, looking in the Opposite Specification of Letters Patent.

direction, of thedevice in the shape which it assumes as the result of being driven.

The same reference characters indicate the same parts wherever they occur.

The wear-resisting member consists of a strip or plate 10 of suitable sheet metal made from a flat blank, and, in the example illustrated, bent between its ends so that it has top and bottom curved edges 11, 11, and side edges 12, 12, which are brought toward each other as the result of the bend between them.

The cross-sectional shape of the top edge prevails throughout the depth of the device, except at the bottom edge, and that is of the same shape except at its extremities which have beveled faces 13- When the device is to be driven, it is placed upon the work whose surface is indicated in F ig, 2 by the broken line a: so that the beveled edge 11 will'lie upon the surface of the work. Vhen the device is driven into the work, the portions which are beveled are deflected from their normal course by reason of the action of the beveled faces upon the work. The curved portion of the device, midway between the edges 12, 12, moves squarely into the work but the beveled portions become displaced with relation to the rest of the device so that the shape of the device changes to that repre sented by dotted lines in Fig. 2. The device thus becomes automatically interlocked in the work when driven.

In the example illustrated, the beveled faces 13, 13, are formed on the inner side of the device, the outer side being left in its original condition so that the beveled portions will diverge when the device is driven. The invention is not, however, limited to diverging relation of the beveled portions, nor to the shape in which the plate is shown.

The advantage of shaping the device as explained and shown, is that it does not mar the surface of the leather. The shape of the entrance made by the foremost edge is the same as the shape of the top edge, and the top edge may lie flush with the surface of the leather without being distorted.

I claim A wear-resisting member consisting of a sheet of metal of uniform thickness having parallel top and bottom edges, and having eled faces for deflecting the extremities a curve between its side edges whereby they when the member is driven. 10 are brought toward each other, said curve In testimony whereof I have affixed my extending uniformly from the top edge to signature, in presence of two witnesses.
