JOHN M. JONES, OF PALMYRA, NEIV YORK.
PAPER-CUTTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 234,409, dated November 16, 1880.
Application filed July 14, 1880.
To all whom it may concern Be it known that I, JOHN M. JONES, of Palmyra, in the county of Wayne and State of New York, have invented an Improvement in Paper-Cutting Machines, of which the following is a specification, reference being had to the annexed drawings, in which Figure 1 is a side elevation of my improved paper-cutter. Fig. 2 is a plan view of the same. Fig.3 is an end view of the same. Fig. 4 is a detached view, showing the curved rack and spur-pinion.
My invention relates to paper-cutting machines; and it consists in the peculiar construction and arrangement of parts hereinafter described, whereby the adjustment of the paper and operation of the machine by the workman without change of position are permitted, the operating-lever being for this purpose located at or near one end of the machine and connected by gearing with the knife or blade, as hereinafter explained.
My improvement in operating the knife-bar of a paper-cutting machine is represented in the accompanying drawings, in which A A is the frame of the machine T, the table; S S, the standards; 0, the cross-bar; B, the knifebar; a, the knife; G G, the bevel-gears, and H the hand-lever.
My improved machine is constructed in the manner customary with hand-power papercutters, and is provided with a suitable frame, A A, tableT, suitable slotted standards S S arising therefrom and connected at their upper ends by the cross-bar O.
The knife-bar B is supported on dlagonal links I l, pivoted to the crossbar O, and has the usual diagonal cutting movement within slots in the standards S S. A spring, 8, attached at its upper end to the cross-bar and at its lower end to the knife-bar, holds the knife-bar up when not in operation and counterbalances the weight of the lever H.
The knife-bar B is provided at one end with a curved rack, It, having teeth on its lower curved side for engagement with the teeth of the spur-pinion P, as represented in Fig. 4. The rack is of a curved form suitable to keep (No model.)
its teeth all the time in mesh with the teeth of the pinion P as the knife-bar descends with a diagonal motion imparted to it by the pivoted links I Z.
The spur-pinion P is connected with the bevel-gear G, and they rotate on a shaft, 6, Fig. 1, which is supported by means of suitable curved brackets (1 cl, fastened to the standard S, or cast in one piece therewith.
The bevel-gear G, to which the hand-lever H is attached, is carried by a suitable stud fastened to the frame of the machine. The gear G meshes with the gear G, and transmits the motion of the hand-lever to it, from which, by means of the pinion P and the rack R, the knife-bar and knife are operated.
The directions of the motions of the various parts are indicated by the arrows in Figs. 1 and 3, and the positions of the knife-bar and hand-lever at the lower end of their motion are represented by the dotted lines It and H, Figs. 1 and 3, respectively.
As the gears make but a part of a revolution, it is unnecessary to provide them with teeth on their entire circumference. The gear G and pinion P may be attached to the shaft '0, which is arranged to rotatein suitable bearings in the brackets dd in this case.
My improved paper-cutter is provided with a paper-clamp operated by the hand-wheel D in the usual manner, and it may also have one or more paper-gages on the table.
The bevel-gear G is provided with a socket, f, into which the end of the hand-lever is inserted and held by a set-screw.
I am aware that it has been proposed to arrange the operating mechanism of a papercutter at right angles to the knife-bar, and I make no claim thereto, broadly; but with the arrangement and construction of the parts shown and described I am enabled to greatly facilitate the operation of the cutter.
Having thus described my invention, what I claim is 1. In a papencutting machine, the combination of the knife-bar suspended by links and provided with the rack It, the pinion P, meshing with said rack, hand-lever H, and bevelpinions G'G,'adapted and arranged to transthe hand-lever and pini0n,the whole arranged mit power and motion from the lever to the and operating as described, whereby the op- 10 pinion P, as set forth. erator is enabled to adjust the paper and oper- 2. The herein-described paper-cutter, conate the knife without changing his position. 5 sisting of a table, a swinging knife-barjpro- JOHN M. JONES.
