To all whom zit may concern.-

Be it known that I, FRANCIS MEISEL, a citizen of the United States, residing at Boston, in the'county of Suffolk and State of Massachusetts, have invented certain Improvements in Machines for Cutting Paper and other Materials into Sheets and Delivering and Piling the Same, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,.making part of this specification, in which Figure 1 is a plan of my improved machine for cutting paper and other materials into sheets and delivering and piling the same.

My invention has for its object toimprove 5 the construction of machines for cutting paper and other materials into sheets and delivering and piling the same, whereby the sheets are delivered singly without interfering with each other and so piled on the table that one I sheet will lie directly over the other; and to this end my invention consists in certain novel features of construction and combinations of parts, as hereinafter described, and set forth in the claims.

In the said drawings, A represents the framework of the machine in suitable bearings, in which are journaled two parallel shafts b c, on which are fixed two wide sprocket Wheels 01' cylinders B C, which support an endless carrier-chain D, the rods (1, which connect the links of said chain, engaging the longitudinal grooves e of the cylinders, whereby the chain is caused to travel with a positive motion in the desired direction.

E is the driving-shaft, which carries a gear f, which through a train of intermediate gears (shown dotted in Fig. 2) drives a gear on the shaft 19, motion being thereby transmitted from the driving-shaft E to the endless chain D.

The upper and lower horizontal portions of the chain between the cylinders B C are supported and prevented from sagging, -in case they should become slack from wear or other cause, by horizontal guides 25, Fig. 13, formed on opposite sides of the framework, on which rest antifriction-rolls g, mounted on the ends of the rods cl, by which the links of the chain D are pivoted together. The journal-boxes of the shaft 0 are fitted to slide in horizontal 8o guideways h in the framework, as shown in Fig. 2, and are made adjustable therein by screws 4;, so that the cylinder C can be adjusted to take up any slack of the chain which may be produced by wear or other cause, and thus keep it tightly stretched as desired.

The web 70, of paper or other material to be cut into sheets, delivered, and piled, is drawn from a roll G, which is mounted on a shaft 26, the journals of which rest in suitable bear- 9o ings in the framework, said web being unwound from the roll by a pair of feed-rolls m n, the shaft of the roll m carrying a gear 19, which is driven by a train of intermediate gears from the gear f on the driving-shaft E.

q is a stationary cutter-blade or knife inclined at an angle, as shown in Fig. 1, and extending transversely above the chain D, said cutter-blade being made adjustable in a stock orsupport 33 by means of a screw q, 10:)

Fig. 11, and r is a rotary cutter-blade or knife "cooperating with the stationary blade (1 and secured to a cylinder H, the axis of which is parallel with the edge of the stationary blade g.

In order to produce a shearing cut, the rotary cutter-blade r is inclined to the axis of the cylinder II, and the inclination of both of the cutter-blades, as described, causes the web while in motion to be cut at right angles to the direction of its length. The cylinder H is also provided with longitudinal lags 31, arranged around its circumference, said cylinder being rotated by a gear 35 on its shaft 65, which meshes with and is driven by one of the train of gears connected with the driving-shaft.

As the paper is drawn into the machineby the feed-rolls m a it passes between the stationary cutter-blade q and the rotating cylinder II, the lags 34E of which by their frictional contact with the paper serve to carry it forward and deposit it upon the rods (1 of the chain D between tapes sand s,which assist in carrying it along until seized by one of the several sets of grippers K with which said chain is provided. The lower tapes .9 are secured to the rods (Z of the chain D, each tape ext-ending from a rod in front of one set of grippers to a rod immediately in the rear of the next set of grippers. The upper tapes-9 run over pulleys 17 18, the pulleys 17 being mounted on levers 10, secured to a stationary shaft 20, and the pulleys 18 being mounted on a shaft 21, which carries a gear 22, meshing with and rotated by an intermediategear 27, meshing with the gear f on the drivingshaft. If preferred, the upper tapes 3 may be dispensed with and stationary rods substituted therefor.

The speed of the chain D is greater than that of the paper as itis fed forward, and the grippers K are so arranged and operated, as will be presently explained, that they will overtake and seize the front end of the sheet the instant before or after it has been severed from the web by the cutters, the severed sheet being then carried around with the chain and deposited upon a table L beneath the same, as shown in Fig. 2, and as the chain travels faster than the web of paper entering the machine a separation of the sheets is effected as they are carried around by the grippers, which produces the required space or interval between each sheet and the following one to enable them to be properly deposited upon the table L without interfering with each other, it being necessary that one sheet should drop onto the table before the other overlaps it, which prevents the sheets from fouling each other and causes them to lie fiat on the table. The table L is intended to be provided with suitable well-known means (not shown) for lowering it automatically in proportion as the pile of sheets increases in thickness.

I will now describe the construction of the grippers and the manner in which each set is operated to seize the front end of the sevcred sheet and afterward release the same to permit it to drop onto the pile on the table L, reference being had particularly to Figs. 2, 5, 6, 7, 8, and 9. Between two opposite links t if of the chain D is secured a frame M, Figs. 5, (3, and 7, the bar 36 of which forms the gripper edge, which is provided with a covering of rubber or othcrsuitable elastic substance. The grippers K are secured upon a rock-shaft 37, which is supported in the end pieces of the frame M and carries a pinion 38, with which meshes a toothed sector 39, pivoted on a stud 40 and carrying two antifriction-rolls 41 42, Figs. 8 and 10, which are so placed as to contact, respectively, with inclined cams 43 4-4, projecting from the inner side of the framework A into the path of said rolls. The grippers being open as shown in Fig. 7, and the chain traveling in the direction of the arrow, it will be seen that when the roll i1 is brought into contact with the cam 43 the sector 3!) will be raised, thus partially rotating the shaft 37 and closing the grippers, as shown in Figs. 8 and 10, to seize the front end of the sheet severed by the cutters, the grippers being held in this position by a friction retailiingspring 45, which bears against a cam-shaped wheel 46 on the gripper-shaft, the end of the spring resting in a notch or depression 47 when the grippers are open, as shown in Fig. 7, and against the flat side of the wheel 4b when the grippers are closed, as shown in Fig. (5. The sheet is now held by the grippers and carried around with the chain until it reaches a position directly over the table L, when the roll 42 is brought into contact with the lower cam 44, which then moves the sector 3.) in the opposite direction, thus opening the grippers and releasing the sheet, which then drops onto the table beneath. In the machine here represented the chain is provided with three sets of grippers K, arranged at equal distances apart; but any suitable number of sets may be employed to meet the requirements of the case.

The cam 44 turns the gripper-shaft 37 nearly one-half a revolution, which carries the edges of the grippers when open out of the way of the paper, so that they will not scrape the printed surface.

In order that the sheet may be carried down onto the pile on the table L as quickly as possible after being released by the grippers, I employ in connection with each set of grippers a series of fingers 50, having their outer ends bent at a right angle, as shown. The several fingers of each set are secured to a rock-shaft 51, to one end of which is secured an arm 52, carrying a roll 53, which is brought into contact with a stationary inclined cam 51, Figs. 2 and 9, on the frame A, the instant after the sheet has been released by the grippers, whereby the arm 52 is depressed against the stress of a spring 55, and the bent ends of the fingers carried down with a quick impulse or movement, thus instantly pushing down the paper, I preferably employ an auxiliary device consisting of an air-pipe P, pro-- vided on its under side with suitable perforations or apertures, through which an airblast is directed onto the paper to depress the same, the pipe P being connected with a suitable pipe containing air under pressure.

This pipe P, which extends longitudinally" over the center of the table L, is provided at its outer end with a distributer composed of a transverse piece 56, having three branches 57 each perforated on the under side, as shown in Fig. 4-, whereby the force of the airblast at this point is increased to insure the rear end of the sheet being quickly forced down onto the pile on the table L. The airblast from the centrallyarranged pipe P serves to depress the sheet of paper along the center of its length, which. permits the air thereunder to escape at the side, so that it will drop quicklyonto the top of the pile on the table L. The branches 57 of the air-pipe P are each open at the outer end, which causes the air discharged therefrom to act on the advancing sheet to retard the same and prevent it from being carried forward beyond its proper position.

The table L is provided on all four sides with sheet-jogging fingers 'R, which are secured to rock- shafts 60, 61, 62, and 63, and project upward above the level of the table, as shown in Fig. 2. These fingers R are sinultaneously swung inward after each sheet is dropped, and serve by their contact with the edges of the sheets to even up the pile and keep the sheets in position one directly over the other. The fingers R are operated in thefollowing manner: To the shaft of the cutter-cylinder H is secured a cam-wheel S, Fig. 12, having a cam-groove 66, with which engages a cam-roll 67 at the endof a connecting-rod 68, (shown dotted in Fig. 2,) which is pivoted at its lower end to an arm 69, secured to the outer end of a horizontal shaft 70, Fig. 3, to which is secured an arm7l, connected by a link 72 with an arm 73 on the shaft 60, which is provided at its opposite ends with bevel-gears 75, which mesh with bevel-gears 76, secured to the roclnshafts 61 and 62, the latter having at its opposite end another bevel-gear 78, which meshes with a bevel-gear 7 9 on the rock-shaft 63, and in this manner as the rod 68' is reciprocated by the cam-wheel S the shafts 60, 61, 62, and 63 are simultaneously rocked to effect the desired inward and outward movements of the jogging-fingers, as previously described, while the table L is at the same time being automatically lowered in proportion to the increase in the height of the pileof sheets thereupon.
