IMPROVEMENT IN MACHINES FOR BENDING BARS OE METALL titre Srigchule rifatta tu in tigrse'ftittrrs ntrnt :mh mating gaat nf tige time.

Bc it known that I, OBED LONG, of Joliet, in Will count-y, and State of Illinois, have invented a new and useful Machine for Bending or Forming Rods or Bars of Metal into I-Iooks, and also into Eyes, such as are commonly made at a shop withv hammer and anvil; 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 draw ings, making a part of this specification, in which- Figure 1 is a perspective view; and

Figures 2, 3, and 4 are views of sectional parts.

The nature of my invention consists ot` a device for bending and formingrods or bars of iron or other metal into the form cf hooks and also eyes.

In iig. 1, a represents the main frame, resting at either end upon a bench, and bearing the reciprocating head-blocks b sliding thereon, by means of the two connection-rods e e, attached to the cranks of the shaft CZ, operated by the foot of theoperator on the trip e, causing a reciprocating motion to the block b. Two connection-rods are used, as shown in' tig. 1, to give uniformity of motion te either end of the head-blocks b. f represents a weight attached to the crank g, for the purpose of sliding the head-block Z) back as soon as the operator lifts his foot from the trip. 7L represents an adjustable former held to its place by the thumb-serew z'. The bar of metal is placed between the head-block Z) and the fermer z, with the outer end touching the gauge j, which is set at any distance so as to regulate the length of the hook or eye. After the bar is so placed the head-block l is moved forward by the foot on the trip so as te press the rod or bar tightly against the former,

when the lever 7c is moved around with the friction-roller Z bearing against the rod or bar, and bends the same around the nipple m on the end of theformer, thusforming an eye. To form a hook, the former, shown in iig. 4, is used with a right-angle section at the end, around against which the rod or bar is bent, thus forming a hook. The section at the end may be of any angle, to ferm any shaped hook desired. The lever 7c is attached to the head-bleck 6 by means et' the slotted plates n, both on the upperand under side ofthe same, projecting7 as shown in tig. 1, to meet the lips 0i` the lever 7c, to which they are hinged. By means et' thumb-screws in the slot in the plates, they may be adjusted so as to place the lever-7c in the right position to bend any sized or length red or bar. Figs. 2 and 3 show the nipple and the former' detached. Anysized nipple may be placed in the former to make any sized eye. It is' designed te bend either het or cold metal.

The particular improvement in this invention consists in being able to dispense with the necessity of driving a mandrel in the eye. The nipple m is slightly tapered from the base tothe apex, thus making it easy to remove the eye after it is bent around the nipple.

' Olaz'ms.

What I claim as new in my invention, and desire toY secure by Letters Patent, is-

l. The lever k, with the friction-relier Z, combined with the slotted plates n oz, constructed as and for the purposes described. i

2. I claim the use of the trip c and the weightj' with the crankshaft (Z and the connecting-rods c e, constructed and arranged for the purpose of operating the head-block as'deseribed.

8. I claim the adjustable former 7i, in combination with the nipple m and the gauge j.

4. I claim a combination of all the parts described, substantially as and for the purposes set forth.
