BARB BENDER AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 234,671, dated November 23, 1880.

Application filed J annary 17, 1880.

To all whom it may concern:

Be it known that I, JOHN S. HAYNE, of Marshalltown, in the countyof Marshall and State of Iowa, have invented a new and valuable Improvement in Barb Cutters and Benders; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side view of my improved barb cutter and bender. Fig. 2 is an end view thereof. Figs. 3, 4, and 5 are details. Fig. 6 is a perspective view of the hook-staple; and Figs. 7, 8, and 9 are details.

This invention has relation to improvements in machines for cutting, bending, and forming wire-fence barbs.

The object of the invention is to devise a machine that will out, form, and bend rapidly and etfectually the staple portion of that description of barb for which Letters Patent of the United States No. 200,783, dated February26, 1S7S,were granted to L. T. InWing.

The nature of the invention will be fully set forth hereinafter.

In the annexed drawings, the letter A designates a strong metallic bed, usually of the form of the letter and having at the angle of the wings a raised table, B. Upon this table, and at one end of the bed or platform, are pillow-blocks, A B, in which the main driving-shaft (J has its bearings. This shaft is operated by a suitable pulley, and is provided near post A with a bevel-gear, a, that engages a similar gear, 1), upon an obliquely-arranged crank-shaft, 0, having suitable bearings in the said post and bed. The shaft 0 actuates an endwise-lnovable slide, 0, working in guides c upon the bed through the medium of a pitman, G. This slide carries at its end next the table a tool, I), the object of which will be hereinafter explained. The drivingshaft carries in its end beyond cheelr block B a longitndinally-slotted cranlrarm, 0, having a wrist-pin, 0, adjustable to or from the shaft, and connected by means of a pitman, D, to a lever, D, upon one end of a crank-shaft, 1);, having its hearings in uprights (1 on the bed-plate. The crank d of this shaft is connected by a pivoted link, d, to a griping-dog, c, mounted between bearings 0 upon the end of a slide, E, reciprocating endwise through guides fupon the bedplate to and from the end of the guide-plate E. This is composed of two steel plates,g g, in the upper one of which is made a groove, 1', for the passage of the wire out of which the bent staple is made.

The wire is passed through a guide-hole, i, between the bearings 0 under the dog 0, and through the adjacentend of the groove 2', and is intermittently fed by the reciprocation of the slide in regular steps of equal length under the cutting knife or die j. This has an oblique cutting-edge, and is removably secured to an eccentricallypivoted holder, F, on the pillow-block or upright B. This holder is a triangular metallic plate pivoted by a suitable bolt to the said block at one angle, carrying at its front lower angle the die j and having at its apex at cam-notcl1,j. A'vibrating movement is imparted to this knife-holder, thus causing die j to be brought in contact with and raised from the bed-knife by means of a tappet. 70, upon the main shaft. The cuttingedge of the die jis oblique to the length of the guide-groove 27, and consequently cuts the wire obliquely, forming points on each end of the staple-blank. The wire is guided, as it is fed, by a finger, l, on the upper guideplate, g, across two parallel shoulder-flanges, l, upon the table B, the knife descends, severs the wire, and the tool b on the end of the slide 0 is advanced, strikes the blank, and, entering between the said flanges, bends the wire into the form of a staple across the shoulders of said flanges. The staple thus formed rests across a hole in the table between the flanges l, the said hole being usually rectangular in form, and a second bending-tool, H, then descends, the first being retracted, and bends thestaple over the edges of said hole transversely to its length, causing it to take the form shown in Fig. 6. This being accomplished, the bent staple is carried through the hole by the tool and dropped under the table. The tool H is vertically arranged, and has endwise movement through guides 75 in an upi right, J, erected on the table and derives motion from the slide 0. This upright has journaled in an overhanging portion, m, an angular vertically vibrating lever, K, the weight end of which is connected by a link, 6 to the shank of tool H, the power end of the said lever being connected to a vertical stud,n, on the slide by means of a link, 0.

It is evident that when the slide is reciprocated vertical vibration is imparted to the angular lever and endwise reciprocation to the tool H. The relative arrangement of the mechanical devices is such that the moment the staple-forming tool I) is retracted the sta ple-bending tool H descends, and when the former is advanced the bender is retracted. Consequently they never interfere.

A score, 8, is formed in the table between the flanges Z, in which the tool 1) works, thus striking the staple-blank with the middle of its bearing end, and never failing to carry the said blank between the shoulders of the flanges. Similar scores, 5, are in the contiguous faces of the flanges, to receive the bendingtool H, in order that it may fall accurately across the branches of the staple and bend it into the desired form.

It will be observed that the steps by which this bent staple is made are as follows, and in the order given: First, the wire is intermittently fed to the knife, then cut into lengths, the blanks bent into staples, and the staples bent transversely of their lengths to form the hooked part.

I do not wish to be understood as confining my invention to the devices specifically hereinbefore mentioned, there being many modifications thereof which might be used without going beyond the scope of my invention.

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

1. In a machine for forming hook-staples, the combination, with the parallel flanges l 1, an intermittently-actuated feed mechanism thrusting the wire across the interval between said flanges, a cutting device dividing it into lengths, and a reciprocating tool forcing the length between said flanges and bending it across their shoulders into staple form, of a tool operating vertically across the staple and forcing it through a hole in the machine, the whole constructed and arranged to operate substantially as shown. and described.

2. Thecombination, with the vertically-shouldered parallel bearing-flanges I, an opening in the bed between said flanges, and a feed mechanism and guide directing the wire across the interval between said flanges, of-thc horizontally-reciprocating tool b O, pitman G, crank-shaft G, the main shaft 0, geared thereto, the vertically-reciprocating tool H, the angular lever K, and the links l 0, uniting said lever respectively to the tool H and slide 0', substantially as specified.

3. The combination, with a bed, A B, having the spaced upright flanges l and an opening between said flanges, of the slide 0", carrying the tool I), the pitman G, crank-shaft 0, main shaft 0, geared thereto, the crank c, pitman D, double-crank lever D, the link d, horizontally-reciprocating slide E, having a grip ing-dog, e, and the grooy ed guide E, substantially as specified.

4:. The combination, with the feed device, the guide E, the staple-shaper 0 b, the staple-bender H, a driving-shaft, G, and mechanisms coupling said devices and shaft, of the 0s cillating die-holder F, having the die 9' and cam-notch j, and a tappet, 70, upon the main shaft engaging said notch, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN S. HAYNE.
