GAUGE FOR PAPER-CUTTING MACHINES Application filed February 1927. Serial No. Zl65,7'34ld My invention relates to means for gauging the successive cuts in paper cutting machines,

whereby a quick and accurate adjustment of the paper pile may be made in order that successive cuts may be at accurate right angles to each other.

vide a movable and accurately adjustable tion therewith, to provide a fixed side gauge for the next successive cut.

at accurate right angles to each other, when the front out has been made and the paper it so happens that the rear uncut edge of the pile thus turned is not at right angles to the first cut, it is necessary to jog the pile accurately against the slde gauge. To accomplish this takes considerable time and trouto the knife cut.

ble where the side gauge is fixed, and in addition the adjustment may not be accurate.

It is to remedy this difficulty that my invention is directed, and it consists of that certain novel construction and arrangement of parts whereby the side gauge may be movable and readily and easily adjusted against the paper pile to obtain the desired accurate right angle cut for the successive operations on the paper.

I have illustrated only so much of the paper cutting machine as may be necessary to explain the construction and operation of the side gauge.

In the drawings Figure 1 is a plan of one corner of the cutting table showing the position of the gauges. l Figure 2 is a side elevation of same.

The cutting table is indicated at 1 supportusual back gauge is indicated at 3, the front edge of which is set accurately parallel to the cutting knife indicated at 4. This back to gauge slides in the usual grooves in the table ters Patent is top, and is adjustablein the usual way by the indexed band wheel indicated at 5. y A

The side gauge is set .at accurate right angles to the knife and comprises a bar 6 which is mounted near. either end on studs 7,

4. In a paper cutting machine, the combination with a cutting table, cutting knife and an adjustable back gauge for the paper pile, of a side gauge set at right angles to the cutting knife, studs for holding the side gauge in its set position, gears threaded on said studs, and means for rotating said gears to reciprocate the side gauge in parallel.

5. In a paper cutting machine, the combination with a cutting table, cutting knife and an adjustable back gauge for the paper pile, of a side gauge set at right angles to the cutting knife, studs for holding the side gauge in its set position, a plate to guide the studs with gears threaded on the studs, and means for rotating the gears to reciprocate the side gauge in parallel lines.

6. In a paper cutting machine, the combination with a cutting table, cutting knife and an adjustable back gauge for the paper pile, of a side gauge set at'right angles to the cutting knife, studs for holding the side gauge in its set position arranged in pairs, a plate to guide the studs with gears threaded oppositely on said studs, and a rack bar simultaneously engaging said pairs of gears to drive said studs and to reciprocate the side gauge in parallel lines.

8. In a structure of the class described, the combination of a table, a gauge support mounted at the side of the table, a gauge bar slidably mounted on said support, adjusting screws for vsaid gauge bar, adjusting members having threaded engagement with said adjusting screws, means for simultaneously actuating said adjusting members, and a second gauge member adjustably mounted on said table at'right an les to said gauge bar.

9. In a structure of the class described, the combination of a table, agauge'bar, adjusting screws at each end of said gauge bar, disposed transversely thereto, means for simultaneously adjusting said screws whereby the bar is unlformly ad usted, and a second gauge disposed at right angles to said gauge bar.
