IMPROVEMENT IN woon-BENDING MACHINES.

Specification forming part of Letters Patent No. l 12,5753, dated March 14, 1871.

f- Toa/ZZ whom) it may concern/Q- Beitknown that I, E. A. CONNER, of Metropolis, in the county of Massac and State of Illinois, have invented a new and useful Improvement in `Machines for Bending Plow` Handles; and `I do hereby declare thatthe following is a full, clear, and exact descripp tion thereof,whichwill enable others skilled in the art-to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure Irepresents a side elevation of my `improved apparatus, with a handle. ready to be bent.` "Fig`.`2 represents a side' elevation,

The nature of my invention relates to imp provements in machines for bending plow and other similar handles, the object of which is to provide a more effective machine than those nowin use. I

` fIt consists infan arrangement of vmeans 1 wherebyT the handleto be bent may be laid on a bench in a suitable position, and the end to be bent grasped between a former bendinglever and a :binding-strap, and be bent up to the desired form by amovement of the lever,

. as will bemore fully described on reference to the `accompanying drawings.

A representsa bench, to which is hinged a right-angled foot-lever, B, and which is also provided with a .block, C, having a sliding plunger, c, ttedtherein. The long arm of the lever B is provided with a notched connecting-rod, which passes up through a slot in the bench, and serves asa handle for raising the leverand acatch for holding it up.

E represents a bending-lever, provided with lugs a, and hinged to a right-angled bracket, to whichlatter is secured the end of a exible s I represents another fiexiblemetal strap,

provided with a metal bracket at one end, and at the other with a link.

e represents a hooked rod, which hooks into the bracket of the strap I at one end, and at the other in an eye in the said strap near the link d under the said strap, the bench being recessed to provide room, as shown. K represents a former having a curved face corresponding to the curvature which it is desired to give to the handle, which face is also grooved, into which groove the rounded portion of the handle is bent in -the act of bending. The former K is provided with lugs a a', corresponding with those on the lever-handle E, as before described. When a handle is to be bent, it is slipped through the Fig. 1, and the former placed on it in the po` sition shown in the same figure, the strap I being laid upon the strap G. rIhe foot-lever B is then unlatched and the handle forced lengthwise by the pressure of the foot on the lever B against the brackets on the end of the straps. The lever'is then turned down into the position shown in Fig. 2, and the bending is accomplished, when the hook e may be hooked into the bracket and the eye on the under side ofthe strap I, which holds the handle in the bent position, which may be taken out of the machine and laid away to set the weight.

L prevents the longitudinal pressure on the handle, caused by the foot-treadle, from doubling up the joint between the handle and the bracket F when -in the position shown in Fig. 2. Having thus described my invention, I claim las new and desire to secure by Letters Patent- Witnesses:
