To aZZ whom it may concern;

Be it known that I, SAMUELJ. liIURRAY, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Machines for Cutting Printed Sheets of Card- Board or Pasteboard into Strips, of which improvement the following is a specification.

My invention is particularly designed for machines employed for separating into single columns of prints (preparatory to punching) a sheet of pasteboard or card-board imprinted with a congerics of designs or pictures-such,

for example, as go to make up a pack or deck of playing-cards. in machines of this class commonly employed the sheet is fed directly in between the feed-rollers, and accuracy of cutting is made to depend on two causes, both variable and imperfectto wit, first, an extremely skillful manipulation, and, sccondl y, strict rectangularity and uniform thickness of the advancing sheet-edge to the lines of demarkation between. the rows or columns of prints to be separated from one another. The difficulty of securing these pre- 3 requisites causes many sheets to be spoiled in the act of cutting by the running of the cuts over the printed matter, or so near to it as to destroy merchantable syn'nnetry of the finished cards. I overcome this difficulty by a provision by which the act of the operator which slips the drive-belt onto the loose pulley is made effective to simultaneously elevate the pressure-roller, thus enabling the attendant to arrange the sheet in strict alignment with the gage while its forward portion is well advanced under said roller, so that on starting the machine the roller closes automatically down upon the sheet at right angles to the demarkations, with the result of feeding the sheet in strict parallelism thereto, no matter how much out of truth the front edge may be. In the accompanying drawings, Figure 1 is a perspective view of a machine embodying my improvement-s, (portions of the pulleys being broken away,) the belt occupying the loose pulley and the upper feed-roller being consequently elevated. Figs. 2 and 3 are ver tical sections of the feeding, cutting, and delivery members in their inoperatlve and operative conditions, respectively. Fig. at shows (No model.)

the geared connections of the rotating members. Fig. 5 shows the conneetinggears of the treadle and the belt-shifter detached.

A may represent any suitable frame, to which are firmly attached the feed board or platform B, the delivery-chute C, and the guides or tracks Cr. Journaled in bearings in the frame are the delivery-rollers D E and the feed-roller F. Journaled in one vertical plane are the shafts H and I of two coacting gangs of rotary cutters, J K. The shaft H carries fast and loose pulleys L L, which operate in customary manner with a driving-belt, M, provided with a belt-shifter, N. The shaft H is connected by gearing O to the feeding-rod ers, the cutter-shafts, and the lower delivcryroller, respectively. The belt-shifter N is connected by rack P with a pinion, Q, upon the shaft R of a treadle, t5, whose normal or inactive position (see Fig. 1) is secured by a spring, T. This position of the treadle corresponds to a position of the shifter N, which holds the belt upon the loose or inactive pul- 18y L.

To the above-described parts, which may be 7 5 substantially similar to parts of like functions on machines heretofore in use, I add, for the purpose of securing absolute accuracy of cuts, the following devices: Apressureu'oller, U, is so journaled in brackets V, secured by hinges o to the platform, as in its lower position (see Fig. 3) to rest upon the feed-roller F. hen the treadle mechanism is in the condition it assumes if left at liberty, (in which the belt shifter is held in the vicinity of the loose pulley, and in which the machine is consequently I at rest,) the said pressure-roller U is elevated Figs. 1 and 2, and so as, in the depressed con- 3 dition of the treadle, to forcibly depress the said pressureroller a little in advance of resumption of its rotation, as shown in Fi 3.

To enable the attendant to place the sheet accurately upon the platform, I provide two gage-fingers, of which finger 1 is attached by set-screw 2 to a stretcher, 3, of the frame near the rear of the platform, and of which the other finger, 4, is attached by set-screw 5 to a shaft, 6, which is journaled in bearings 7 near the front of the platform, and is provided with a handle, 8. These two fingers, having been accurately adjusted in alignment with a central cutter, are fixed to such adjustment by tightening of the sct-screws 2 and 5. Vhile the machine is at rest, the attendant, taking the sheet in one hand, with the other hand momentarily elevates the nearer finger 4 by means of handle 8, and so arranges the sheet upon the platform as to bring the printed guide-mark upon the sheet coincident with the fingers, and its forward portion underneath the elevated pressure-roller. De-

pression, now, of the treadle operates first to bring the pressure-roller forcibly down upon the sheet, and while said roller continues thus depressed to rotate all the revolving mem bers, as indicated in Figs. 3 and t, causing the sheet to be fed forward, cut, and delivered in the condition of narrow strips.

a rotary gang of cutters, and a feed-roller, of

a belt-shifter and a pressure-roller, which are so geared, substantially as described, to said treadleshaft as for said pressure-roller to rise and fall with changes in elevation of the treadle, as and for the purpose set forth.

In testimony of which invention I hereunto set my hand.
