" IMPROVEMENT IN PAPER-CUTTING MACHINES.
Specification forming part of Letters Patent No. 124,690, dated March 19, 1872.
To all whom it may concern:
Be it known that we, J OHN hammers and PRns'roN VAN HORN, of Brooklyn, Kings county, New York, have invented, made, and applied to use certain Improvements in the Construction of Paper-Cutting Machines; and that the following is a full, clear, and correct description of the same, reference being had to the accompanying drawin g'makin g part of this specification, and to the letters of reference marked thereon, in which- Figure 1 is a view of our improved papercutter, the knife being thrown up. Fig. 2 is a view of the same, the knife being depressed.
In the drawing, (made one-half the size of the model,) like parts of the invention are designated by the same letters of reference.
The nature of the present invention consists in certain improvements in the construction of paper-cutting machines, as more fully hereinafter set forth; the object of the invention being more particularly to operate the knife of the machine readily and with the eX- penditure of as little power as possible.
To enable those skilled in the arts, to make and use our invention, we will proceed to describethc construction and operation of the same.
A shows the frame of the machine, provided with a cr0ss-head, B, and with a table, 0, up-
on which the paper to be out is placed. D show boxes inserted in the sides of the frame, which boxes I) are adjustable, and have pivoted within them the ends of the links I the opposite ends of which are attached to the knife-bar G, in the lower portion of which is held the knife E. H shows a connection, one end of which is pivoted within the knife-bar G' at the same point at which one of the links F is pivoted, while its opposite endis passed through the partially-slotted end of the curved leverI, a pin being passed through the lever and-the connection. I shows a curved lever, made of any desired length, the lower end of which is geared and partially slotted to receive one end of the connection H. J shows a link and counter-balance combined, the link receiving the geared end of the lever I, by which the machine is operated, and being pivoted so as to move freely, to the lower portion of a segment-rack, K, at a point which forms the center of the same. K shows a segmentrack secured to the frame A, with which rack'the geared endof the lever I engages as the lever is depressed and elevated. L shows a clamp secured in the side frame, employed to clamp the paper, and operated in the usual Way. M is a stop secured upon the face of the knifebar, which, when the knife is depressed, is
brought into contact with a set-screw, 19, se-
cured in the side frame.
Such being the construction, the operation is as follows: The paper to be cut is placed upon the table 0 of the machine, and is clamped in position by depressing the clamp L. The lever I is then depressed by the operator, its geared end engaging with the segment-rack, and, through the connection attached to the knife-bar, as shown, the same is drawn down, carrying the knife through the that'but little power is required to operate the machine, while the position of the geared end of the lever being adjustable at pleasure, so that it may engage with the segment-rack at any desired point, the operator, should he have a small quantity of paper to cut, may, by adjusting the lever to the rack, cut the same with a shorter movement of the lever.
Having now set forth our invention, What we claim as new is-- In the combination, consisting of the knifebar Gr, links F, connection H, lever I, link J, and segment-rack K, we claim the lever I, having a'toothed end operating in connection with the segment-rack, substantially as described.
