FEEDING, CUTTING, AND PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 580,985, dated April 20, 1897.

Application filed May 15, 1896. Serial No. 691,680. (No model) To aZZ whom it may concern: framework of the machine, in suitable bear- Be it known that I, FRANCIS MEIsEL, acitiings in which runs the driving-shaft B, carzen of theUnited States, residing at Boston, in rying at one end, outside the framework, a the county of Suffolk and State of Massachudriving-pulley C, Fig. 1, and a pinion, shown setts, have invented certain Improvements in dotted, which meshes with the gear a on the 5 5 Feeding, Cutting, and Printing Machines, of shaft of one of the plate-cylinders, from which which the following is a full, clear, and exact gear a motion is communicated through the description, reference being had to the accommedium of suitable gears to various other panying drawings, making part of this specificylinders, rolls, and moving parts of the malo cation, in which chine, to be hereinafter described.

Fig. 6 is an elevadrawn from a roll I, which is mounted on a tion of one end of the first impression-cylinshaft 15, the journals of which rest in suitable der, showing the stationary gripper-cam and hearings in a carriage F, sliding on horizontal the annular support to which it is secured. ways at the end of the framework and operz 5 Fig. 7 is a vertical section of the gripper-cam ated by a rack and pinion 16 17, as shown in and its annular support, taken on the line 7 7 Figs. 1 and 3, said web I) being unwound from of Fig. 4.

As the web of paper is drawn into the machine by the feed-rolls e d it passes between the stationary cutter-blade c and the rotating cylinder K, the lags 28 of which, by their frictional or rubbing contact with the paper, serve to carry it forward and deposit it upon the lower tapes g, which run over pulleys h at the same surface speed as the impression-cylinder and cooperate with the upper tapes 6, running over pulleys k, and as soon as the sheet is severed from the web by the cutters it is carried forward between said tapes g 2' over a table L, which is provided with a series of upwardly-projecting pins or projections in and is made movable vertically and also in a forward and lateral direction by mechanism to be presently described. As soon as the sheet has been carried into a position over the table L and just before it reaches the front gages n the said table is slightly raised, which causes its pins m to lift the sheet clear of the lower tapes g, as shown clearly in Fig. 3, but not sufiiciently high to come into contact with the upper tapes i, which merely prevent the sheet from being raised by the air,immediately after which the table is moved forward and simultaneously swung to one side, the said combined forward and lateral movements of the table causing the sheet supported on the pins m to be brought with absolute certainty squarely and evenlyagain st the front and side gages n 1) before it is seized by the grippers q of the first impression-cylLnder G, whereby if the sheet should be afterward fed in by hand to the same or another machine for a second impression on the same or upon the opposite side perfect register would be insured, which would not be the case if the tapes were relied upon to bring the sheet up to the gages.

The mechanism by which the various movements are given to the table L will now be described, reference being had particularly to Figs. 8, 9, l0, and ll. Near each of the four corners of the table L, on the under side, is a boss or projection 33, provided with a vertieal stud 34, Fig. 11, which enters a hole in a link 35, which is pivoted to swing on the upper end of a short bar 30, which is fitted to slide vertically in a bearing in a lug 37, projecting from the inside of the framework. The supporting-bar 3G is provided with a pin 38, which projects out therefrom through a slot in the lug 37 and carries at its outer end an antifrietion-roll 39, fitting within a camslot in a lever 40, fulcrumed atstl, the two levers on the same side of the table being connected by a rod 42, and one of said levers having pivoted to it a short rod 43, jointed to a link ll, pivoted to the framework, and 011 the pin which connects the rod 43 with the link all is a cam-roll which is acted upon bya cam 4C5 on a shaft it, connected by gears with the driving-shaft, whereby as said cam i5 is retated the levers 40 are rocked to raise and lower the table L at the proper times. The two levers it) on the opposite side of the table L are actuated by similar mechanism receivin g motion from another cam 45 at the opposite end of the shaft l6, as shown in Fig. 2. To an arm l7, projecting outward from one of the links 35, as shown in Fig. 2, is jointed a rod 48, which is pivoted at its opposite end to a lever 40, carrying a cam-roll which is acted upon by a grooved cam Z1 secured to the shaft 46, whereby as soon as the table L has been slightly raised to lift the sheet off the tapes 1 it is swung in a horizontal plane on its four pivoted links 35, which gives it a forward and lateral movement, thus bringing the sheet resting 011 the pins m squarely and evenly against both of the front gages n n and the adj ustable side gage p, as before described, the table being returned to its normal position after the sheet has been seized and carried forward by the cylinder-grippers q,which are opened and closed by mechanism hereinafter described. The front gages H are mounted, as usual, upon a rock-shaft 50,which is actuated to lift the gages at the proper time by a rod 51, operated by suitable cam and lever connections. (Shown dotted in Fig. 3.)

The length of the sheet severed from the web by the cutters can be varied by changing the surface velocity of the feed-rolls with relation to that of the rotary cutter-cylinder K. This is effected by the employment of a change-wheel M, Figs. 2 and 3, which is removably secured to the shaft 46, which also carries a gem-52, which gives motion through two intermediate gears 54: to the gear 31 on the shaft of the cutter-cylinder K.

The change-wheel M meshes with an intermediate gear 56, rotating on a stud 57, mounted upon a supporting-arm 58, swinging 011 a shaft 5!) and held in place when adjusted by a clamping-screw 60, passing through a slot 01, said gear 56 transmitting motion through intermediate gears (52 G3 to the gear 18 on the shaft of the lower feed-roll b, and thus by removing the change-wheel M and substituting another having a different number of teeth the speed of the feed-rolls with relation to that of the cutter-cylinder can be varied, as desired, to change the length of the sheet cut from the web.

As soon as the sheet is seized by the grippers q of the firstimpression-cylinder G, said grippers having been opened and closed for this purpose by mechanism hereinafter dcscribed, it is carried between the cylinder G and the first form-cylinder D, receiving an impression therefrom, after which, if it is not to receive a second or perfecting impression on the opposite side, it is carried around past a wedge-shaped guide N and between tapes 12 and the cylinder G to the first accumulatingcylinder P, which is provided with a fly (36, which deposits the sheets upon a table R, Fig. 1, the grippers q being operated to release the sheet at the instant that it is seized by the grippers 67, Fig. 5, of the accumlating-cylinder P. The guide N is formed by the angular points of a series of bands 1", which partially encircle the cylinder H and are secured to suitable supports. (Not shown.)

The cylinder P, which accumulates a certain predetermined number of sheets to be removed by a single operation of the fly 66, is of the ordinary well-known construction, which forms no part of my present invention and will not be further described.

The grippers q of the first impression-cylinder G are mounted on a rock-shaft 70, to one end of which is secured a pinion 71, which meshes with a sector-gear 72 at the end of a lever 73, pivoted at 74, Figs. 4 and 5, to the end of the cylinder G, said lever carrying a roll 68, which is acted upon by a cam Q, having two removable portions secured to a stationary ring-shaped support 75, attached to the frame A and located opposite and close to the end of the cylinder G, as shown in Fig. 6. As the cylinder G revolves the roll 68 is brought into contact with the cam Q, thereby moving the lever 73 to open the grippers to receive the sheets against the resistance of a spiral spring 76, encircling a rod 78, which is pivoted to the lever 7 3, its opposite end passing through a guide lug or projection 80, said spring serving to close the grippers on the sheets as they are fed against the front gages n by reason of the roll 68 passing out of contact with the cam Q at about the point Q Figs. 4 and 5. When the sheet is to be carried around by the cylinder G and delivered to the accumulating-cylinder P, the central portion 81 of the cam Q, is removed and the inclined portion 82 moved into the position shown in Fig. 5, so that the roll 68 will not come into contact with the cam until the end of the sheet is in a position to be seized by the grippers 67 of the accuinulating-cylinder P, but when the machine is to be used as a perfecting-press and it is desired to have the sheet pass under the guide N and around between the second or perfecting pair of cylinders E H the entire length of the cam Q is used, as shown in Fig. 4, which causes the roll 68 to be brought into contact with the point of the cam Q to open the grippers q just before the sheet reaches the angular points of the bands 1", which form the guide N, the front or leading end of the sheet being then pushed out from the surface of the cylinder G to cause it to pass under the guide N by an out ward thrust of a series of pins 83, Fig. 4, commonly called shoo-fiy pins, which are operated in a well-known manner by mechanism not shown. These shoo-fly pins are intended to be thrown out of action when the sheet is not to be delivered to the perfecting impression-cylinder H. The grippers q can thus be arranged to open at different points by changing the cam Q so that the sheet can be released at the proper place to allow it to be seized by the grippers of the first accumulating-cylinder P when a sheet is to be printed on one side only, or so that the sheet can be released at a different place when the paper is to be printed upon both sides.

The guide-bands 7', which lie close to the cylinder H, leaving a space for the passage of the sheet, are arranged to come opposite to the margins or spaces between the several printed forms, and each of these bands is provided with a series of apertures 84, as shown in Fig. 8, through each of which projects a guide-roll 85. The guide-rolls 85 are secured to shafts 86, extending across the machine parallel with the axis of the cylinder H and supported in bearings in lugs 87, projecting from the bands 1*, each shaft carrying at one end a small gear, (not shown,) which meshes with a large gear (not shown) inside the framework, whereby the rolls are rotated with the same surface velocity as the cylinder H and caused to carry the sheet by their friction thereon around said cylinder H to the platecylinder E, from which it receives a second impression upon the side opposite to that first printed, after which it is carried by the rolls 85 to the second accumulating-cylinder S, Fig. 1, similar to the cylinder P, first described, and provided with grippers 88, operated at the proper time to seize the sheet, said cylinder S being provided with a cooperative fly 89, which serves to remove the sheets after the required number have been collected on the cylinder and deposit them upon a suitable table similar to the table R. (Shown at the lefthand side of Fig. 1.)

The rolls 85 are employed to carry the sheet to the second plate-cylinder, and thence to the accumulating-cylinder S beyond for the reason that it is impossible to provide the second impression-cylinder H with grippers, as they would intefere with the offset-web T, which is operated in the usual manner by being unwound from one roll and simultaneously wound up on another, as shown in Fig. 1. The offset-web T passes over a transverse guide-bar w, Figs. 1 and 4, preferably of triangular shape in cross-section, as shown, and located between the accumulating-cylinder S and the perfecting impression -cylinder H, whereby a narrow throat is left for the passage of the web, which then passes from the upper right-hand edge of said bar u; up around the guide a, preferably of roller form, located above and to the left-hand side of the guidebar w, whereby the direction in which the offset-web travels is abruptly changed at an angle to permit the sheet to be seized by the grippers 88, which are ready to seize it as soon as its front edge is brought above the upper edge of the guide-bar to at the point where the offset-web passes off at an angle to the guide a, said web after leaving the guide a passing directly to the roll 90, upon which it is wound up.

When it is desired to feed in by hand for a second impression on the opposite side sheets that have been previously printed on one side only, a board can be placed over the table L upon suitable supports, in which case the sliding carriage F, which supports the web, feedrolls, cutters, &c., is moved back out of the way, so as not to interfere with the operation of feeding in the sheets by hand.

It is obvious that any number of pairs of form and impression cylinders with grippers can be added bet-ween the first and last pairs of cylinders and that accumulating-cylinders can be attached to any or all of the pairs to take the sheet away from the impression-cylinder.

From the foregoing it will be seen that the above-described machine can be very advantageously used for very high-class work and also for that of a lower grade. For very fine work the sheets can be taken from the web and rapidly printed on one side only, as the machine can be run at a high speed, the sheets being afterward fed into the same or an other machine by hand for a second or perfecting impression, while if ordinary work is required the machine can be used as a perfecting-press and also run at a high speed, advantages not combined in any one machine with which I am acquainted.
