IMFROVEMENT IN BOLT-CUTTERS.
Specification forming part of Letters Patent No. 141,265., dated July 29, 187 3; application filed December 5, 1872.
' for adjusting and operating the cutter, as will hereafter be more fully set forth.
Figure 1 is a side elevation of my invention. Fig. 2 is a section of the same; Fig. 3, detached views of the eccentric. Fig. 4 shows a bolt in position.
a represents the frame, which consists of a single piece,'bent or cast in the shape shown,
leaving the open space between its sides, and
having itsend secured in any suitable manner to the cross-piece -b. Moving up and down between these sides, and kept in position by the grooves in its edges, is the cutterframe 0, which is swiveled to the upper end of the handle 01 by means ofthe set-screw or other device 0. This handle has a screw-head out upon its upper end where it passes through the cross-piece b, so that by turning it in either direction the cutter-frame 0 can be adjusted up or down, as may be desired- Swiveled to this frame 0, by means of the pin "6, is the hand-lever h, the upper end of which forms the eccentric shown in Fig. 3, and which 0pcrates the cutter is. The end of this cutter passes through the cross-piece l, which serves as a guide to it, and which is constantly kept in position by means of the springs 0, which may be of rubber, or any other material.
It will be seen that the frame is beveled at the point r on a line with the edge of the cutter, as shown in Figs. 2 and 4. o
The frame reaches over and takes hold ot the nut, causing the nut to form an abutment while being out.
As the hand-lever is moved so as to force the cutter upward, the cutter moves with a rolling-like motion, so. as to gradually make the out; and by adjusting the cutter-frame upward by means of the handle from time to time great additional leverage is obtained.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is-- y .1. The springs 0,- placed upon each side of the cutter, substantially as specified.
'2. The combination of the frame, adjustinghand'le, cutter and cutter-frame, and camlever, when all combined to operate substantially as shown and described.
In testimony that we claim the foregoing as ourinvention we hereunto affix our signatures.
