Description

UNITED STATES PATENT OEEIoE.
GEORGE H. SANBORN, OF NEW YORK, N. Y.
IMPROVEMENT IN PAPER-CUTTING MACHINES.
Specification forming part of Letters Patent No. 84,306, dated November 24, 1868.
To all whom t may concern:
Be it known that I, GEORGE H. SANBORN, of the city, county, and State of New York, have invented a new and useful Paper-Cutting Machine; and I do hereby decla-re the following to be a full and correct description of the same, reference being had to the accompanying drawings, in which- Figure l is a rear elevation of the machine.
The nature of the invention consists in han ging the knife-bar eccentrically to two gears, pivoted to the frame, and operated simultaneously by two worms on one shaft, by which arrangement a sliding or drawing motion is given to the knife while going down, and a short horizontal cut when it has reached the table, thus insuring the severing of the last sheet of paper, the whole machine being simple in construction and iirm and steady in its operation, all as hereinafter more particularly set forth.
In the accompanying drawing, A marks the `frame of the machine, which is strongly made of wood or iron. B is a winch on the end of the worm-shaft C, showing the point of application ofthe driving-power. D D' are wormwheels keyed onto shaft 0. E E' are sheaves turning loosely on shaft O, and receiving the end-thrust of the worms D D.
The worm-wheels D D' engage and drive the two gears F F', which turn on pivots b b', attached to brackets G G', projecting from the frame A. The knife-bar H is hung eccentrically upon the two gears F F' by the pivots c c'. K marks the table upon which the paper to be cut is placed while subjected to the operation of the knife.
It is obvious, from the construction, that as the gears F F' turn, the knife H is carried up and down with a lateral or "draw" motion, and that at the instant of reaching its lowest position, in contact with the table K, it has a short horizontal movement. The movements being all positive, firmness and certainty are given to the operation of the machine.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
The combination of the knife-bar H, gears F F', and worm-wheels D D', constructed and operating in the manner and for the purpose specified.
The above specification of my said invention signed and witnessed, at New York, this 16th day of October, A. D. 1868.
GEO. H. SANBORN.
