SPECIFICATION forming part of Letters Patent No. 274,741, dated March 27, 1883, 4 Application filed September 30,1882. (Model.)

'm` make and use the same, refereneebeing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specilication.

This invention has relation to improvements 15 in clip-benders.

It consists in the construction, combination, and arrangement of the several parts, as will be hereinafter fully described, and specifically pointed out in the claims.

zo In thedrawings, Figure lis a plan view, and

Fig. 3 is a side View, part in section, of a machine constructed according to my invention. Fig. 2,is a sectional view, showing a modification in the clamping-block; and Fig. 4 is a de- 25 tail view, as will be described. A represents the bed-plate. It is provided with a groove, a, extended from one end, and formed with inclined sides to correspond to the inclined sides of the slide, as shown in Fig.

3o l and hereinafter described.

b is a rail, mountedon bed-plate c near the end opposite the slot a', and extending transversely from side to side over the bed-plate, as shown. The sides o'f this rail are beveled in- 3 5 wardly from top to bottom, as shown.

B is the shaping-head, which may be made a solid block under certain circumstances, which I will hereinafter describe. I prefer, however, to construct it of two bars, Z1 b2, pro- 4o vided in their edges with mortises made to fit and slide snugly on the rail b. The bar b is provided with an opening, which is tapped with afemale thread corresponding to the righthand thread on the adjusting-screw c, herein- 4 5 after described. The bar b2 is provided with an opening in line with lthe opening through` bar b', and this opening is formed with a iemale thread corresponding to the left-hand thread on screw c. i

5o o is the adjustingscrew. It is mounted in lugo and provided at its outer end with an angular shank, so it may be turned. It is cut with aright-hand thread on its outer end, which works in the opening through bar b', and with a lefthand thread on its inner end, or end next 5 5 the lug c', and this portion works in the opening through bar b2, as shown. Thusl by turning 1 this screw the bars b b2 may be brought close together, as shown in Fig. l, or may be set any suitable distance apart, thus regulating 6o the size of the clip in the operation of the device, as will be described.

cl is the clamping-block, arranged immediately in front of the inner ends of' barsb b2, and of a width equal to these bars when closed, 65 as shown in Fig. 1. In Fig. 2, I show this block provided with an elongated slot, through which is passed the bolt d2, by which it is secured to the bed-plate by means of a nut screwed on said bolt and bearin g on either side of the slot, 7o as shown.` This block, it will be seen, can be adjusted forward and backward to accommodate the machine to the various thicknesses of the iron desired to be bent, and also permit the easy removal of the bent clip. I regard 75 this construction as a modification of my invention, and prefer the construction shown in Figs.i1,3, and 4, and hereinafter described.

In these figures, d is the clamping-block, bent from a metallic plate, and having the lower 8o edges of its side portions bent to enter grooves in the sides of a guide-plate, d', as 'shown in Fig. 4. This guide-plateis securedvto the bedplate by bolt d2, and is extended to provide support for thejaws d3 d3, in which the clamp` 85 block-operating lever is pivoted. dlrepresentsarod extending across between and connecting the side bars of the clampblock at a point near its upper rear end.

'erepresents the clamp-block lever. Its for- 9o ward end is bifurcated to provide the bars e e', and it is pivoted on the lugs d3, as shown.

e2 are curved slots cut through the bars e' e', and arranged in line with each other, and eccentrically with reference to the pivotal point 95 of the lever, as shown.

The forward end ofthe levercrests between the side plates ofthe clamping-block, with the bars e' close to the plates d3, as shown in Fig.

1. The rod d* passes through the slot e2, and 10o e emga-11 the clamping-block d and its operating-lever e are thus connected, as shown.

f is a slide constructed to t and placed and sliding in the groove c', formed in the bedplate a, as shown. j

f is a rail similar in shape to rail b, and secured on the slide f.

f2f3 are bars provided in their lower edges with mortises, cut to fit on the rail j" as the bars b bdo on rail b. These bars are provided with threaded sockets, in which works the right-and-left-hand adjusting-screw g, which is mounted on lug g', and operates substantially like the adjusting-screw c, as has been described. The ends of the bars b bzare rounded on their inner face, as a better action is thus secured on the iron being bent.

f4 is a loop secured on the slide fnear its end.

f5 is a lever pivoted to the bed-plate a on one side of the slide f. It passes through the loop f4, and is extended on the opposite side to provide a handle and give proper leverage in the operation of the machine.

fifs are supports for the iron being bent. They are secured to the sides of bars fzff, and extend forward therefrom, as shown. I prefer to secure these supports to the bars by screws passed through elongated openings,'so they may be adjusted up or down, as may be h represents the iron being bent.

In the operation of my invention the iron It is placed between the clamping-block and the ends of bars b b2, the said block being in the positionshown in Figs. l and 3, and the slide f being in the position shown in dotted lines. Iheleverf5 is then carried, with the slide f and bars fzf, into the position shown in full lines, bending the iron h, the operation being clearly illustrated in Fig. 1. It will be seen that by turning the adjusting-screws c and g the bars b b2 andfzf3 may be set so as to bend clips of any desired width. When the iron is placed between the clamp-block and the bars b b2, and the barsf]03 are forced up, bending the clip, and withdrawn, the iron is often wedged in tightly between the bars b'bzand the clampblock; and to obviate this difficulty I have provided the lever e, connected with and operating the clamp-block.

It will be seen that when the clamp-block vand the lever are in the position shown in Fig. l the block is held firmly in position for the iron to be placed between it and the bars b bz to be bent. When the iron has been bent, the end of the lever e is thrown up, drawing the clamp-block back away from the iron, which may then be easily removed.

It will be understood that the sliding clampblock could be adjusted back. and forth by other means than the lever with curved eccentric-slots. For instance, a lever might be secured to it and arranged to engage teeth of a ratchet-bar arranged alongside. I prefer, however, the construction shown and hereinbefore described.

. The utility of my machine is not conned to the bending of clips; but it is of advantage in the manufacture ot' seathooks, stake-irons, double-tree irons-in fact, all irons requiring a square bend-and by changing the form of the ends of bars b b2, around which'the iron is bent, a round or oval bend may be made.

Instead o f using the bed-plate, the parts mounted thereon can be secured on the floor of the work-shop, though I prefer its use, as the machine is thus rendered portable.

When the clips to be bent are of a uniform size and the iron is of the same thickness', it will be understoodthat the shaping-head B could be constructed of a solid block, and that the bars fzf need no lateral adjustment.

It will also be seen that when the inner size of the desired clips is uniform and the thickness of iron Varies the shaping-head may be made ofa single block; but it is necessary to make the bars f 2 f3 adjustable laterally, so they may be conformed to the varying thickness of the iron; and when clips ot' different size are .required it is necessary to make both the shaping-head, which I then construct of two bars, and the barsfzf3 so that they may be adjusted laterally to the size of clips desired.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

In a machine for bending iron, the combination, with the shaping-head B and the clamp-block d, arranged in line with and close to the end of the shaping-head B, of the clamping or bending bars fzf, placed on opposite sides of and sliding longitudinally close to the shaping-head and clamp-block d, and means for operating the clam ping-bars f2 f3, substantially as and for the purposes set forth.
