UNITED STATES FIIIGE,

PATENT IMPROVEMENT IN THE MEANS 0F ATTACHING THE SOLES T0 BOQTS AND SHOES.

Specification forming part of Letters Patent No. 106,0l0, dated August 2, 1870.

fdiameters, with the larger' diameters or prominent portions rounded.

The second feature of my invention relates to a form of nail or wire with a head on one end; and consists ina piece of wire, round, oval, triangular, quadrangulalgor any form in its cross-section, but longitudinally having a succession of larger and smaller diameters, with the larger diameters or prominent portions rounded, and having a head on one end.

Referring to` my drawing, Figure l shows two longitudinal sections of my staple-wire.

Fig. 2 shows a longitudinal section. representing a series of parallel wires connected to each other at one end. Fig. 3 shows the various forms in cross-section. Fig. 4 shows a new form of nail or wire, with a head on one end of it. Fig. 5 shows a piece of the round wire,

also a section with the indentations angular,

while the prominent portions are rounded. Fig. 6 represents longitudinal sections of my wire at right angles to that shown in Fig. 2.

a b a on the dotted line A, Fig. l, is a longitudinal section of my staple-wire, taken in the dotted line B, showing its whole length; and a on the dotted line B is a longitudinal section through one end of my staple-wire, taken in the dotted line A.

a, a a, Fig. 2, show the series of wires connected at one end by the metallic strip b b', and are longitudinal sections in the dotted line O or O', and may be pressed out of a sheet of metal having indentations on its sides, as shown in the crosssection of the sheet represented by a, Fig. 6; or the sides of the sheet may be plain, as represented in the crosssection at a', Fig. 6, which are longitudinal sections of the wire 4or fastening for the Soles of shoes or boots, after having been pressed from the sheet, taken in the dotted line D, Fig. 2. 1

a l 2 3 4 5 6, Fig. 3, show six of the crosssectional forms in which my wire may be made, though I do not limit myself to these, as the cross-sectional form may bevaried indefinitely, while, longitudinally, it has a succession of larger and smaller diameters, t-he larger diameters being rounded.

ct, Fig. 4, shows my new form of nail or wire, with a head, c, on one end, which is a longitudinal section of the same. This may be substituted, in some cases, for the staple-wire, or that shown at Fig. l.

bis the middle part of my staple-wire, which commonly rests upon the interior surface of the sole, or upon the interior surface of the vamp when said vamp rests upon the upper surface of the sole, and parallel to their surfaces at the parts where driven in, while the ends a a pass through the u'pper and into the sole.

b Z1', Fig. 2, holds a similar position as b, Fig. l, in resting upon the surface of the leather, while the wires a a a pass through the upper and into the sole. wire a, Fig. 4., occupies a similar position, and these three parts 12,12', and c perform a similar servicethat is, they secure the upper in certain cases to the sole more securely than the simple wire, as shown at a, Fig. 5; and all of these, 1;,11, and c, may be partially or entirely embedded in the leather which they secure to the sole.

I make `my wire by takin g the wire of commerce, iron, brass, or any suitable metal usually round in its crosssection; and if I wish to have it round when completed, I run it between a pair of rolls having semicircular grooves in their perimeters, and in these grooves'have successive indentations of suitable size and form to impress the proper form on the wire, as described, when it passes between a pair of these rolls, and if the wire is not vperfectly formed by passing through one pair, it may pass through a second pair at right angles to the first, which will complete it.

The oval wire is formed by having one pair of the rolls nearer to each other than the other pair.

The triangular wire is formed by having Also, the head c on the,

three rolls Work together, With their Workingsurfaces properly indented; and the quadrangular wire in like manner requires four rolls; and if it is desired to have the sides of the angular Wire convex, the Working-surfaces of these rolls are made concave.

The indentations in the sides of the Wire may be angular, as shown at u, Fig. 5; but the Wire is better and easier made with the smaller diameters rounded as well as the larger.

In preparing my staple-Wire for use it is taken from a reel, passed through rolls to give it the proper indentations, as shown at a, a, or a", Fig. 5. Y' It is then cut into suitable lengths and bent by machinery1 in an obvious manner, and it may have any form in its crosssection suitable for the purpose of fastening the soles on shoes and boots, as those shown in Fig. 3, or any other, provided that it is made into a staple form.

I make the wires, as shown in Figs. 2 and 6, by first rolling the proper ndentations into the sheet of metal, and then punching them out in the form shown in Fig. 2, and having a cross-section, as shown at 6, Fig. 8, showing a section in the dotted line at D, as at a., Fig. 6, having indentations on all sides; but if the indentations are only on tivo sides, then the section at D will appear as at a', Fig. 6that is, made of a plain sheet; but these Wires may be pressed into any form in their cross-section, and in their longitudinal formy their indentations and prominent portions maybe as a, a, or a, Fig. 5.

In the third part my invention-that is, the simple manufacture of Wire not bent into the staple form, not in connected series, nor having a head on one end-may have a longitudinal form, as a and a, Fig. 5, and a crosssectional form, as 3, 4, 5, and 6, Fig. 3, or any other which may be found useful for the purpose described, except round and oval, which have been previously patented.

The headed wire a, Fig. 4, may be made of wire of longitudinal form, as a, a, or a, Fig. 5, and as l, 2, 3, 4, 5, or 6, Fig. 3, or any other useful form in its cross-section. It is then taken from a reel and fed through an instrument which cuts it into proper lengths, at the same time striking a head on each piece.

These different kinds of Wire are suited to different kinds of work, and each may be said to have its peculiar advantages When used on the work for which it is specially adapted, and, in accordance with this, the staple-Wire and the headed Wire are best suited to those turnshoes where the Wire passes through the upper and into the edge of the sole, and nearly parallel to its surface.

The Wire shown at Fig. 2 is best suited to those turn-shoes which have the upper leather placed directly on the upper side of the sole, the wires passing through the upper and into the sole at right angles to its surface, and, in this case, a series of wires is taken, suficient to extend entirely around the sole near its edge, and are pressed through the upper and into the sole at one operation by means of a suitable press, so that the sole can be permanently attached to the vamp by this method, and with this form of Wire, in equal or less time than will bc required to last the shoe preparatory for the attachment ofthe sole by any other method in use.

The staple-Wire will answer very Well for the lastnamed shoe.

The simple straight Wire, having the longitudinal form of a or a, Fig. 5, and any of the forms i, 2, 3, 4, 5, or 6, Fig. 3, :in their crosssections, is better adapted to attach the soles to the uppers of those shoes and boots which are not turned after the sole is attached.

By the term turn shoe or boot,7 I mean those which have their soles attached to the vamps or uppers While wrong side out, after- Ward to be turned and finished.

My drawings are all on a large scale, some iive or six times the diameter required for use in ordinary shoe Work.

Some of the advantages of my manufacture of wires are as follows:

They can be made entirely by machinery, and bring the manufacture of shoes and boots more in the control of machinery than any system in use. With my wires an operative can do much more Work inthe same time, thereby reducing the cost. My Wires have a greater holding power than any others in use, on aci i i i i i count of all their prominent parts being' rounded, thereby enabling them to pass smoothly into the leather Without cutting, tearing, or mangling its fibers, as all Wires do which have sharp edges or angular points presented to the leather as they pass in, thus giving my Wires, When in their places, the advantage of having the unbroken bers of the leather contract close onto the Wires at their smaller diameters, in such manner that, when the leather becomes dry and rigid, and thus pressing closely into all the indentations of the wire, as Well as their prominent parts, will give them a greater holding power than any wire in use.

My staple-wire and the connected Wires, (shown at Fig. 2,) in addition to the rapidity and cheapness in which the Work can be done by their use, make it possible to attach the sole to the upper of a turn-shoe in which the upperis placed directly on the upper side ot' the sole, securing it in a firm and durable manner by means of the horizontal portions b and b', binding the upper in its place, making both a cheaper and better .turn-shoe than any hitherto made.

With this description of my invention, I claim- 1. As a new article of manufacture, a Wire for attaching the soles of shoes and boots to their vamps, having a succession of larger and smaller diameters With the larger portions rounded, substantially as shown at a a. af,

seotion, and having a head, o, on one end, as and for the purpose set forth.
