MACHINE PQR MANUFACTURE OF WIRE STIRIPS The Schedule referred to in these Lettere Patent and making part of the same.

To all whom 'it concern.-

Be it known that I, THADDEUs FowLER, of Seymour, in the county of N ew Haven, and State of Connecticut, have invented certain new and useful Improvemeuts in Machines for Preparing Strips of Metal for the Manufacture of Wire; and I do hereby declare the following to 'be -a full, clear, and exact description of the same, reference being had to the accompany `ing drawings, making a part of this specification, in

which Figure 1 represents a perspective view of the machine.

Figure 2 represents a vertical cross-section throughv the same.

Figures 3, 4, and 5, are illustrative ofthe diculty heretofore encountered in preparing and creasing strips for the manufacture of wire, and of the means essayed for avoiding that difficulty.

Similar letters of reference, where they occur in the y separate figures, denote like parts in all Aof the drawings.

In the manufacture of wire from strips, as practised by me, it was found that theoutside wires of the s trip,

I(always one on each side, and sometimes two on each side,) were so slack of metal as to be comparatively Worthless for round wire, and could only be used -where a perfect form of cross-section was ntinaterial, as, for instance, in telegraph-wires.

The object and purpose of my invention was to avoid this loss, or waste, ofthe outside wires, and I have accomplished` it, as will be hereinafter explained.

My `invention consists in combining, with a pair of creasing-rollers, a guiding-table and a pair of compressing-rollers, whose axes'are at right angles to the axes of he creasing-rollers, so-that, as the strip is fed up to,

or before Vitis fed up to the creasing-rollers, its edges shall be compressed, or fulled up, suficient to supply the deficiency of metal at the edges, when it has passed through between the creasing-rollers.

To enable others skilled in' the art to make and use my invention I will proceed to vdescribe the same with reference tothe drawings.

In or on the base, A, is placed a housing, or pillarblocks, B, in which a. p'air of creasing-rollers, G O, is hung, and rotated by any suitable power and mechanism.

The creases d a a, &c., in these` rollers, are semicircular, so as to form, where they pinch, or rll together, a series of circular grooves. Y

On the base, A, is also arranged a feeding-table, D, having aggroove, b, therein, wide enough to receivcand guide the strip of metal to be operated upon.

In or on the table D, there are arranged two compressing, or felling-rollers, E E, whose axes, c 0,.-are at right angles to the axes of the creasing-rollers() C;v

The perimeters of the compressing-rollers are slightly grcoved and rounded at e, and project slightly beyond the edges vor wallsof the groove b, in the table, and the compressidg-rollers E are, moreover, let down intothe table, so that their perimeters will bear or take against the edges of the strip of metal, as it is drawn orfed past or between them, and full, or thicken them up, while the gauge of the centralportion of the plate is not changed.

When the plate is not fulled up at the edges, the

wires made therefrom are slack, or flat at the edges, as seen at 1-2, while those, 3, in the central portion of the plate are perfectly round. rlhis attened condition is dueto the 'spread ofthe metal under the pressure of the rolls, and it must go to the edges, of I course.

By thickening up the edges ofthe strip, as shown at 4-4, iig. 5, and then creasing it into incipient wires, itag'aiu spreads out to its original width, asseeu, at5, same gure, and the wires made therefrom are all, even 1 tothe extreme outer ones,` perfectly round, as shown at Tghe compressing-rollers E, aer they have fulled up the edges of the plate, become, to a great extent, if not entirely, the directors of the plate, or strip, beyond that point, and up to where it enters between the creasingrollers.

The plate, or strip, as will be observed atv fig. 5, is

compressed and contracted, as at 4, but, after passing
