Abstract
Abstract A rod forming mechanism comprises a frame including suitably joined and reinforced vertical, parallelly disposed walls being open at one of their vertical ends; a rod securing guide being mounted to the frame, the guide providing means for retaining a selected length of rod in a vertical position distally adjacent the open vertical edge of the frame; and a rod forming assembly including a forming lever pivotally mounted at its center to the frame adjacent the open end, a roller mounted at the lower end of the forming lever, means for applying force rotating the forming lever at its pivot provided at the end of the forming lever opposite the roller, a return bend shoe being disposed between the frame walls with the lowermost terminal end of the shoe being in substantial alignment with the pivot of the forming lever, and a stationary forming roller being disposed rearwardly of the lever, between the frame walls.

Claim 1
Independent Claim
202 words
A rod forming mechanism, comprising: a frame including suitably joined and reinforced vertical, parallelly disposed walls being open at one of their vertical ends; a rod securing guide being mounted to said frame, said guide providing means for retaining a selected length of rod in a vertical position distally adjacent said open vertical edge of said frame; and a rod forming assembly including a forming lever pivotally mounted at its center to said frame adjacent said open end, a roller mounted at the lower end of said forming lever provided at the end of said forming lever opposite said roller and means for applying force rotating said formed lever at its pivot, a return bend shoe being disposed between said frame walls with the lowermost terminal end of said shoe being in substantial alignment with said pivot of said forming lever, and a stationary forming roller being disposed rearwardly of said lever, between said frame walls, the distance between said actuating lever pivot and the center of said stationary roller being sufficient to accommodate said roller carried on said lever and thicknesses of rod when said roller carried on said lever is disposed between said return bend shoe and said stationary roller.
Claim 2
Dependent Claim
202 words
A rod forming mechanism, comprising: a frame including suitably joined and reinforced vertical, parallelly disposed walls being open at one of their vertical ends; a rod securing guide being mounted to said frame, said guide providing means for retaining a selected length of rod in a vertical position distally adjacent said open vertical edge of said frame; and a rod forming assembly including a forming lever pivotally mounted at its center to said frame adjacent said open end, a roller mounted at the lower end of said forming lever provided at the end of said forming lever opposite said roller and means for applying force rotating said formed lever at its pivot, a return bend shoe being disposed between said frame walls with the lowermost terminal end of said shoe being in substantial alignment with said pivot of said forming lever, and a stationary forming roller being disposed rearwardly of said lever, between said frame walls, the distance between said actuating lever pivot and the center of said stationary roller being sufficient to accommodate said roller carried on said lever and thicknesses of rod when said roller carried on said lever is disposed between said return bend shoe and said stationary roller.
Claim 3
Dependent Claim
34 words

Claim 4
Dependent Claim
26 words
The apparatus of claim 2 wherein said stop is provided with means for adjusting the vertical position of said stop with respect to said frame walls.
Claim 5
Dependent Claim
25 words
The apparatus of claim 1 wherein said guide is provided with means adjusting the interior dimension of said guide to accommodate various sizes of rod.
Claim 6
Dependent Claim
22 words
The apparatus of claim 1 wherein said lever pivot and the center of said stationary forming roller positions are in horizontal alignment.
Claim 7
Dependent Claim
22 words
The apparatus of claim 1 wherein said center of said stationary forming roller is vertically below the pivot of said forming lever.
