METHOD OF MAKING BARBED FENCING.

EPECIEICATION forming part of Letters Patent. No. 389,154, dated September 4, 1888.

Applicafi-m filed December 27, 1887. Serial No. 258,980. (No model.)

To all whom, it may concern.-

Be itknown that LEDMUND JORDAN, a citizen oftheUnited States,residing atBrooklyn,in the county of Kings and State of New York, have invented certain new and useful Improvements in the Method of Making Barbed Fencing; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention consists of an improved method of manufacturing thin flat barbed fencingstrips having the barbs formed on one edge by preparing blank strips of sufficient width for two barbed strips, cutting barbs along each edge ofsaid double blank strip, bending out said barbs into the required projecting form, and slitting the double blank strip along the middle to separate it and form the two barbed strips therefrom. In some cases I form the barbs close together along the edges of the strips without any waste material; but in other cases, when it is preferred to have them farther apart, I cut away short sections of said edges between the barb forming portions thereof, and I make the barbs in various different forms, as hereinafter fully described, reference being made to the accompanying drawings, in which- Figure 1 is aplan View of bed-dies and horizontal section of movable dies that may be employed for carrying out my invention, together with a portion of a blank strip, showing the method of converting it into two barbed strips. Fig. 2 represents the said dies and strip in side elevation. Fig. 3 represents the devices of Figs. 1 and 2 in end elevation, except the blank strip, which is in transverse section. Fig. 4 represents two short sections of barbed strips in plan view. Fig. 5 represents an edge view of a barbed strip on which the barbs are bent laterally. Fig. 6 is aplan view of a bed'die, horizontal section of movable dies, and plan view of aportion of a strip, representing other forms of dies that may be employed, together with dies represented in end elevation in Fig. 7 and a section of the blank strip for other means of carrying out my invention; and Fig. 8 is a plan View of a partlyconverted strip, representing a modified form of barbs that may be made by my improved method.

In the practical manufacture of blank strips for barbed fencing it is found that a strip of the proper width for two completed barbed strips is the size that may be rolled to the requisite thickness for such strips with the best results in respect of economy of labor and quantity of material, and it is also a means of economy in the subsequent processes of completing the barbstrips to make two barbstrips from one blank, and it is desirable to effect the barbing and slitting at one and the same operation of a single machine; but the barbing of the edges and separating of the strip may be done separately, if preferred. This has been done in various ways of separating the strips along the middle, so as to partly form the barbs by the operation of slitting the blank apart. In my present method the plan is to form the barbs in the outer edges of the double blank strip and separate the two barbed-edged portions along the middle by simply slitting them along a straight line, which may be done by different contrivances of dies, some of which I have represented, as follows: NVhen I prefer to make the barbs a close together along the strip, I will employ a beddie, I), having angular cutting-edges c d on opposite sides, together with a single punch or movable die, 6, or it may be two separate dies having corresponding angular edges adapted to slit the margins of the blankf along the lines 0 d, and thus separate the barbs from the strip so far as they are to be separated. Suitable feeding mechanism will be employed with said dies for shifting the strip along. A short distance from said dies and along the course in which the blank feeds I arrange a stationary bending-die, g, standing level with the top of bed-die b, and having bevel sides h, which converge in the direction of the dies b 6, so that the barbs a,which are bent downward by the dies 12 e, as represented in Fig. 2, will be forced against the bevel sides h by the feeding mech' anism, by which the barbs will be bent out ward to some extent, as shown at 'i, to open them sufliciently for subsequently allowing the points of Wedges j to enter between them and the notches formed in cutting them and complete the bending and shaping. A springlifter, a, is arranged in a socket of die b to lift up the strip and enable the depressed points of the barbs to pass over the top of die 12. \Vhen thus bent out a certain distance on the bevelfaces of the die 9, so that the most depressed portions of the barbs passthe edges of said die, the upward inclination of the barbs from the points backward allows them to pass over the upper end of said bending-die and permits the feeding of the strip along. At a suitable distance from said bending-die and along the same course I arrange the slitting-dies,con-

'sisting ofthe bed-die k and the movable die Z,

having the straight cutting-edges m, adapted to slit the strip apart in the middle, and on the upper die I arrange a former, a, for each edge of the bank,having the shape on the face 0 to the form of which it is desired to shape the barbs on the outer edge, which formers are adapted to project down past the said edges of the barbs and rest while the wedges which I have provided for completing the bending of the barbs rise against the inner convex edges of the barbs and force them out against the formers. These wedges are arranged in guide grooves or ways q, formed in the bed-die it, suitable for them to slide in. They may be operated by any approved contrivanee of means adapted for the purpose, which itis not necessary to represent; but, whileit is preferable to bend the barbs outward in the plane of the strips, as above described, in some cases the projection of the barbs laterally to said plane caused by the dies 1) e may be sufficient, provided said dies are adapted for bending them somewhat more, as in Fig. 5, which I propose to do when preferred, dispensing with the bender g, formers a, and wedges j.

When it is desired to cut away waste portions of the edges of the strip and locate the barbs farther apart, punches s and i may be employed for 'fi rst cutting notches u,and the slits 01' may be cut by other punches; or, if preferred, these slits may be cut simultaneously with the slitting of the blank strip apart by using dies 2) and w, with slitting dies x 1 as representedin Fig. 7; but in this case the barbs of one edge will be bent upward and the others downward. The bending of the barbs outward may be done by other means, as preferred in this case.

The method of cutting away waste portions ofthe edges may also be employed for making taper-barbs, as represented in Fig. 8, and in this case the barbs may be made close together, as in Fig 1, if preferred.

What I claim, and desire to secure by Letters Patent, is-

The method of making barbed fencing,consisting of cutting barbs ,in both edges of a double blank strip, bending said barbs into the required projecting form, and slitting the strip apart along the web between said barbed edges, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

EDMUND JORDAN.
