PAPER TRIMMING MACHINE.
(Application filed Oct. 17, 1898.)

PATENT OFFICE or DAYTON, OHIO.
SPECIFICATION forming part of Letters Patent No. 627,600, dated June 2'7, 1899.
. Application filed October 17, 1898. Serial No- 693,738. (No model.) 7
To all whom it may concern:
Be it known that I, CHARLES SEYBOLD, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented ce'rtainnew and useful Improvements in Paper-Trimmin g Machines, of which the following is a fullQclear, and exact description, reference being had to the accompanying drawing, forming part of this specification.
My invention relates to machines for trimming the edges of bundles of papersuch as books, pamphlets, circulars, and the likeand has special relation to that construction of machines in which a pair of cutting-knives are employed, acting automatically and simultaneously in planes parallel to each other, to trim two edges at a time. The general construction and operation of this class of machines I have fully shown and described in my Letters Patent No. 594,490, of November 30,1897, for a paper-trimming machine; and my present invention relates to a certain improvement in the means for stopping the knives in the proper position to make the necessary cuts, which will be hereinafter more boards, as called for in my above-mentioned patent, by reason of the fact that the guidebars are attached to the movable member of the clamp, they necessarily are affected by any tipping of the clamp due to variation in the height of the paper bundles to be trimmed. It is evident that should the heights of the bundles vary when the clamp-pressure is applied the movable member of the clamp will tip, and this tipping, be it ever so slight, will throw the guide-bars out of line slightly, so that the knives in descending will, on one side, fail to hug the pattern and on the other side may shave off a little of the patternboard. Itis to overcome this objection that my present invention is directed.
In the drawing the figure is a perspective View of the clamp-table and clamp-plate of the paper-trimming machine, showing the gage-bars'for ad justing'the lateral movement of the cutting-knives. I g
The details of the construction of my paper-trimming machine are fully set forth in my above-mentioned patent, and as the presen t invention relates solely to the'clamp mechanism I have not illustrated, nor will I here describe, the main features of the machine itself, but will merelyreferto said patent and Bolted to the under surface of the clampplate 0 by bolts 17 are the pattern-boards c c of the exact size of the bundles of paper to be trimmed, while E E are the cutting-boards on the table A, against which the cuttingknives act.
In the upper ends of the upright posts B B horizontal holes are drilled, within which are mounted the horizontal rods F F, secured therein by set-screws ff. The outer ends of these rods carry the blocks g g, secured by set-screws h h, and provided with a face I of indurated fiber or other suitable material. As described in my above-mentioned pendin g application, these rods B F form stops for the knife-carriers and knives, and they are so adjusted that they will correspond in V81 tical alinement with the edge of the patternblock 0, so as to hold the knives at exactly the position to descend along the sides of the pattern-boards. In my pending application these rods are mounted in slots or grooves cut in the upper surface of the clamp-plate,
shown) to raise and lower the clamp-plate.
so that should the clamp-plate tip under variation in height of the paperbundles secured by the clamp the rods will tip also, preventing the knife on one side hugging closely the pattern-board and allowing the other knife possibly to chip oif a portion of the pattern. With my present construction, however, the gage rods are a part of the clamp-table and are entirely disconnected from the movable member of the clamp, remaining at all times at perfect right angles, and the clamp-plate, with pattern-blocks attached,may tip in either direction to suit the uneven piles without affecting the distance of the knives from the pattern-blocks in the slightest degree.
and extending out horizontally to serve as stops for the cutting-knives, substantially as shown and described.
