Description
UNITED STATES' PATENT (DEEIGE JAMES LINDSAY, or NEW YORK, N. Y.
IMPROVEMENT IN CUTTING-NIPPERS, 62C.v
VSpecification forming part of Letters Patent No. 147,850, datecl'February 24, 1874-; application. tiled September 8, 1873.
Tol all whom it may concern:
Be it known that I, JAMES LINDSAY, oI" the city, county, and State of New York, have invented an Improvement in Implements for Cutting, Griping, &c., of which the following is a specification:
This invention relates to that class of mechanism used for cutting, punching, Stamping, and griping metals in the various operations of metalworking, and it is designed to provide an implement in which much greater power may be given to the jaw or jaws of the implement than has been possible with other devices, for the same or similar purposes, commonly in use; and'it consists in a novel combination of parts whereby the desired object is secured as concerns a tool to be operated in or by the hand without a fixed support or one to be attached, when in use, to such support.
Figure l is a side view of a cutting implement made according to my invention, show ing the same in a closed position. Fig. 2 is a side view of the same, showing it in an open position and indicating` the manner in which, when desired, it may be attached to a fixed support. Fig. 3 is a side view of a modication ot' my invention as applied to punching, Src.
A is that portion of the implement towhich the others are attached, and, as represented in Figs. 1 and 2, comprises a jaw, a, and handle, b. Pivoted to this part A, at c, is a movable jaw, B, the shank c of which extends backward coincident with the adjacent part of A. C isa lever arranged in the same plane with the handle b, and attached, by a pivot, d, to fthe shank c of the jaw B, and by another pivot, e, to the upper end of a link, D, the
lower end of which link works on a pivot, f,
suitably provided in the part A. It will be seen that the portion of the lever between the pivots d e constitutes the short arm of the said lever, and, in conjunction with the link I), provides a toggle -joint, which, by the approach oi' the lever to the handle, is straightened to bring the movable jaw toward the jaw c of the part A.
Vhen it is desired to actuate the'tool with a degree of power greater than that conveniently obtainable'by grasping the lever and handle together by the hand the part A may be bolted or otherwise secured upon a bench or other fixed support, as indicated in Fig. 2,-
and operated by depressing the lever.
When the work required is of a heavy description the part A may comprise a bed-plate, as represented in Fig. 3, formed of cast-iron, and furnished either with a punch and die, as shown at a b in the said ligure, or with suitable devices for cutting, stampin g, swaging, or otherwise treating metal in mechanically manipulating or shaping the same.
It will be seen that by depressing the lever or bringing it toward the part A the jaws are brought nearer each other for cutting, griping, or other purposes, their power increasing in proportion as the pivots d e f are brought nearer in line with each other, the reverse movement of the lever, of course, opening the jaws. rlhe jaws may be of any form adapted to the special work--cutting, griping, stamping, Snc-for which the implement may, in any given case, be designed.
That I claim as my invention isr.lhe stationary jaw A, in combination with the pivoted jaw B, lever C, and link D, arranged to operate substantially in the manner described.
JAMES LIND SAY.
