IMPROVEMENT IN BENDlNG-MACHINES.

Specification forming part of Letters Patent No. 144,109, dated October 28,1873; application filed September 13, 1873.

To all whom it may concern:

Be it known that I, SMITH W. KIMBLE, of Springfield, in the county of Sangamon and State of Illinois, have invented a new and ImprovedBending-Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part of this specification, in which- Figure 1 is a longitudinal vertical section in line 0c 00 of Fig. 2. Fig. 2 is a top view. Figs. 3 and 4 are detail views.

The invention relates to means whereby corn-planter runners may be cheaply, conveniently, and effectually bent and brought into the desired shape, as hereinafter fully described and pointed out in the claim.

A represents a base or platform, from which rises an upright frame, B. On the latter is located the former 0, having the gage-pins 0 near the inner end of the groove 0, in which the blank is entered, and a plain surface, 0 with side bevels-c 0 one on each side thereof. D is a bar projectmg over the former, and whose subjacent surface approaches gradually closer to the former, to allow the bending-roll E to bear upon the tapering blank, and, as it moves over, force it down to the former. F F are side rolls, which, as well as roll E, are placed in the slot of an arm, 9 of the segment G, pivoted at g to the frame. The roll E, how.- ever, is located in a frame, I, which has a friction-roll, e, at top, that bears against the bar D, side arms 6 0 that enable it to slide in guides e c and a cord, 0 which is looped over a spring, 6 H is a pivoted yoke, which is passed over one end of the blank to hold it down in the groove 0. The segment-arm G has a friction arc-surface, 9, against which works a friction-pinion, 9 on a rock-shaft, that is itself operated by two pulleys, one with a straight and the other with a crossed belt.

The shaft, however, may be rocked or vibrated by any suitable means, this forming no part of my invention.

The tapering runner-blank is inserted with the thinner end foremost, while the thicker against the bar D, causes the blank to take the exact bend of the former. When the segment is returned to its starting-point, the roll E is lifted by its spring from the blank, and allows the finished runner to be removed and another blank inserted.

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

A vibratory segment provided with slotted arms, between which are placed the side rolls F and reciprocating top roll E, combined, as described, with a curved convex former, C, and a superposed bar, D, the subjacent surface of the latter gradually approaching the top of the former from front to rear, as set forth.
