SOLE-FASTENER.

SPECIFICATION forming part of Letters Patent No. 331,926, dated December 8, 1885.

Application filed April 3, 1885. Serial No. 161,139. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT VAN WAGEN- EN, of Boston, county of Suffolk, State of lvlassachusettshave invented an Improvement in Sole-Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The object of my invention is the production of a novel solefastener.

My improved sole-iastencr is composed of a strip or ribbon ofsheet metal corrugated or indented and folded about a wire core, the projections or corrugations of the strip engaging the leather or other material into which'the fastener is driven.

Figure 1 represents on an enlarged scale an indented strip or ribbon of sheet metal with central wire core therein, part of thestrip being shown asinfolded within the strip to make solefastening material inaccordance with my invention; Fig. 2, a cross-section of Fig. l in the dotted line as m. Fig. 3 shows a sole-fastener detached, and Figs. 4 and 5 modified forms of strips.

A thin metal strip or ribbon, A, indented or corrugated in any desired manner, so as to present projections or an uneven surface at its outer side, has a wire, B, laid against it, and the strip or ribbon by the action of a suitable die, and by methods well known to those conversant with metal-working, the said strip or ribbon is bent closely about the said wire core, as shown at the left of Fig. l in the section Fig. 2. As the sole-fastening material is severed, the cutter used will sever the matcrial in usual manner, so as to leave a point, as at the left of Figs. 1 and 3. The projections at the outside of the fastener engage the leather and act to retain the fastener in place.

The fastening material made as described may be out into lengths suitable for fasteners in a nailing-machine for boot and shoe Work, or be cut and made into nails to be fed into a machine separately.

In another application, Serial N 0. 161,138,

filed concurrently herewith, I have shown and claimed a solefastener composed of a corrugated or indented strip bent to form a cylindrical body.

If desired, the cylindrical body representing the wire-like material to be cut into short lengths for the production of fasteners may be subjected to a galvanizing-process, to fill any spaces left as the result of bringing the strip of sheet-iron into cylindrical form.

I am aware that nails for solefastenings are commonly indented or serrated. I am also aware that shoe sole fastenings have been made of smooth or plain strips ofmetal folded about a fibrous core, and also that a tubular or tube-like fastener with open center and side has also been used, the fastening separating as it is driven into the leather.

In accordance with my invention, the strip from which the fastener is made is first corrugated or indented, and being done before the metal is put into nailshape, the cost of manufacture is decreased, and there is actually no waste of stock, and the indentations, added to the sheet-metal nail, make that class of nail or fastener operative and valuable. The addition of the metallic core greatly stili'ens the fastener, and the indentations of the strip act in a measure to aid in holding the core in place.

I claim- The herein described sole fastening material, composed of a wire core enveloped by an indented or corrugated metallic strip, all substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

B. J. N oYns, F. CUTTER.
