ROTARY PAPER-CUTTER FOR PRINTING-PRES SES.

Application filed July 899- Elerial N 722,485. (No model.)

To aZZ whom it may concern: its outer end with a larger drivingpinion G, Be it known that I, WINFIELD S. HUSON, of meshing into the cylinder-gear II, by which Derby, in the county of New Haven and State the cutters are driven. The upper cutter I, of Connecticut, have inventedanewImprovewhich is provided in the usual manner with a 5 ment in Rotary Paper-Cutters for Cylinder cutting edge 11, entering the cutting-groove a Printing-Presses; and Ido hereby declare the of the lower cutter A, is mounted upon. a following, when taken in connection with the shaft J, the ends of which are located in fixed accompanying drawings and the letters of open bearings K and K, respectively formed reference marked thereon, to be a full, clear, in the side pieces C and C.

This shaft is provided their normal positions, in which they are held at one end with a pinion D, meshing into an by the engagement of the pin L When,howintermediate pinion E, mounted upon the inever, it is desired not to remove the upper I00 50 nor end of a short shaft F, journaled in the cutter and its shaft bodily from the machine,

side piece C of the frame and provided at but simply to throw the said cutter out of action and temporarily retire it, the handle end J of the shaft J is seized and lifted vertically against the arm L, which, being rigidly mounted upon the rock-shaft M, turns the said shaft and simultaneously lifts the arm L against the under face of the opposite end of the shaft J, whereby both ends of the shaft are simultaneously lifted out of their bearings. The handle end J of the shaft is then pushed rearward, so as to cause the outer end of the shaft to drop into the shallow seat K at which time the opposite end of the shaft will ride up over the bevel K of the bearing K and rest upon the upper edge of the side piece 0 at the point K (Shown in Fig. 4:.) The shaft will rest in this position of retirement until it is desired to again bring the cutters into operation, when the handle end J of the shaft J is lifted and the shaft worked out of its shallow seat K, after which the ends of the shaft will gravitate back into the open bearings K and K. I am thus enabled very conveniently to remove the upper cutter bodily from the press either for sharpening it or for getting it out of the way altogether or to temporarily retire it-as, for instance, when the press has become fouled by a sheet of paper.

I wish particularly to call attention to the fact that although the bearings of the upper; shaft are open and permit the bodily removal; or retirement-of the shaft they are fixed bearings and prevent the shaft from getting out "of alinement when in its operating position, being in this respect superior to pivotal or otherwise movable bearings for the upper shaft.

I would have it understood that I do not limit myself to the exact details of construction herein shown and described, but hold myself at liberty to make such changes as fairly fall within the spirit and scope of my invention.

Having fullydesoribed my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a rotary cutter for cylinder printingpresses, the combination with a lower cutter, of an upper cutter, a shaft upon which the same is mounted, fixed open bearings for the upper shaft, whereby the same may be lifted out of the said bearings, and means coacting with the upper shaft for lifting it into a retired position in the press when it is desired not to remove it bodily therefrom, the said means comprising a rock-shaft and two arms rigidly secured to the respective ends thereof, one arm extending under one end of the upper-cutter shaft and the other arm extending-over the other end of the said upper-cutter-shaft.

2. In a rotary cutter for cylinder printingpresses, the combination with the lower cutter, of an upper cutter, a shaft therefor, fixed open bearings for the ends of the said shaft one end of which is extended to form a handle, a

rock-shaft, and two arms rigidly secured to the said rock-shaft at the ends thereof, one arm extending under one end of the uppercutter shaft, and the other arm extending over the other end of the upper-cutter shaft.

3. In a rotary cutter for cylinder printingpresses, the combination with the lower cut ter, of an upper cutter, a shaft therefor having its outer end extended to form a handle, fixed open bearings for the shaft, a rockshaft, an arm rigidly secured to the said rockshaft and extending over the handle end of upper-cutter shaft,and a corresponding arm secured to the inner end of the rock-shaft, and extending under the inner end of the upper-cutter shaft.

4. In a rotary cutter for cylinder printing presses, the combination with the lower cutter, of an upper cutter, a shaft therefor, fixed open bearings for the upper shaft, a seat formed adjacent to the hearing which receives the outer end of the said shaft for the reception of the said shaft when it is lifted iint'oits retired position in the press, and means coacting with the said upper-cutter shaft for lit-ting it into its said retired position, and comprising a rock-shaft and two arms 'locatedat the opposite ends thereof, and respectively extending under and over the opposite ends of the upper-cutter shaft.

5. In a rotarycutter forcylinder printing- .presses, the combination with the lower cutter, of an upper cutter, a shaft therefor, fixed open bearings for the ends of the said .shaft the outer bearing having a seat formed closely adjacent to its rear wall, and the rear wall of the inner bearing being beveled,:and meanscoacting with the said upper-cutter shaft for lifting it in to itssaid retiredposition, and comprising a rock-shaft and two arms located at the opposite ends thereof, and T6- spectively extending under and over the op posite ends of the upper-cutter shaft.

6. In a rotarycutter for cylinder printingpresses, the combination with a lower cutter, a shaft therefor, gearing between the said shaft and the cylinder-gear, an upper cutter, a shaft therefor, a pinion mounted upon the said shaft, and meshing into a pinion mounted upon the lower shaft from which it is driven, fixed open bearings for the endsof the shaft of the upper cutter, whereby the said shaft may be bodily removed from the press, and means coacting with the said upper-cutter shaft for lifting it into its said retired position, and comprising a rock-shaft and two arms located at the opposite ends thereof,'and respectively extending under and over the opposite ends of the upper-cutter shaft.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
