SHEET-DELIVERY APPARATUS.

SPECIFICATION forming part of Letters Patent No. 345,222, dated July 6, 1.886.

Application filed September 3, 1885. Serial No.`176,084. (No model.)

T0 all whom it may concern: Be it known that I, GEORGE l. FENNER, citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented new and useful Improvements in Sheet-Delivery Apparatus, of which the following is a speciiication.

My invention relates to improvements in sheet-delivery apparatus for printing-presses, which improvements are especially adapted to stop-cylinder presses; and it consists, essentially, in a carrier-reel adapted to directly receive the printed sheet from the impressioncylinder and deliver the said sheet upon a receiving-table properly located to receive the same. The carrier-reel is operated by suitable levers and cams, which connect the same with the main shaft of the press.

The specific construction of the carrier-reel and the other operating parts is more fully pointed out in the following specification aud claims, and illustrated in the accompanying drawings, in which- Figure lis a side elevation of a printingpress provided with my improved sheet-delivery apparatus. of the same. Fig. 3 is a plan or top view of the mechanism for locking the carrier-reel and carriage.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the press-frame, constructed to support the impression-cylinder B and type-bed C in the proper relation to each other. At one end of the press-frame are bearings for the drivingshaft D, from which motion is transmitted by gear-wheels D' D2 to the main shaft E of the press, and from which shaft E motion is in turn transmitted by the usual crank, E', and connecting-rod E2, Fig. 1,to the traveling rackwheel E3, which meshes into a stationary rack, E, on the base of the press, and also engages a suitable rack, E5, which is pendent from the type-bed C, whereby a reciprocating motion is Fig. 2 is an end elevation cylinder is at rest during stated intervals. At a point back of this space in the wheel B the impression-cylinder carries a catch, F, which is adapted to be engaged by a catch-lever, F', which operates to check, hold, andstart the impression-cylinder under the impulse of adjusting mechanism of well-known construction. In the example shown in the drawings this catch-lever is pivoted at f to the pressframe,a'ud is vibrated by means of a cam, F2, which has a suitable way therein, and a rod, F3, connected at one end to the lever, which has on its other end a roller-stud` f', which engages with the way in the cam F2. The end of the rod F3, which carries the rollerstud f', is slotted or bifurcated, so as to clear the main shaft E, and in order to supportthe former a block is neatly tted into the slotted portion, through which block the shaft passes, the whole being arranged to allow the uninterrupted motion of the connecting-rod F3. The impression-cylinder is provided with suitable grippers, B2, for holding the sheet to be printed upon the cylinder, these grippers B2 being opened by stationary trip cams or posts B3 B4, arranged on the press-frame in their proper relative position, and closed by suitable springs, as usual, the whole constituting the main features of a stop-revolution press of Well-known construction. p

G G area pair or racks, secured to thepressframe A in a proper alignment with the impression-cylinder, which racksare arranged directly over the receiving-table II, which is also properly secured to the frame, and these racks G G are engaged by gear-Wheels I I, which gears I I and their shaft I support a carrier-reeLJ, which is constructed to receive the printed sheet from the impression-cylinder B,and transfer the same to the receivingtable H, previously mentioned. The gears I I and their shaft,I shall hereinafter call the reelcarriage. The gear-wheels I I, as before stated, are mounted 4upon a shaft', I', which extends through .a hollow spindle, K, Fig. 2, which spindle can rotate about the shaft I', and carries upon one end a gear-wheel, K', which isconstructed to engage at the proper time with a corresponding gear-wheel, K5, upon the impression-cylinder B, so that a rotary motion is imparted to the spindle K, while the inner shaft, l', and the gear-wheels I I upon IOO the said inner shaft remain stationary in the position shown by full lines in Fig. l until acted upon by mechanism which will be hereinafter described.

To receive the paper from the impressioncylinder, two disks, K2 K2, Fig. 2, are arranged upon the hollow spindle K, which disks can be adjusted toward or from each other and secured in such a position by suitable thumbscrews or the like. The adjustment of the disks is rendered necessary to adapt the sheetdelivery apparatus for varying widths of sheets. manently secured to the spindle K, the said disk K3, however, only acting as a base for the sheet-gripper@ which will be hereinafter more fully described.

It will be observed that, in order to properly deliver the sheet from the impression-cylinder B to the receiving-table H, the said operation must be accomplished while the cylinder is at astop, and that the carrier-reel-J must be retur-ned to its original position in time to receive'the next printed sheet. This motion at the proper interval is imparted to the carrierreel, as follows: To the main shaft E of the press is secured `a heart-cam, I, which rotates with the said shaft, and engages with a rollerstud, l, having bearings on the lower arm Aof a. lever, 1*, which is fulcrumed to the frame at li. This lever extends upward toward carrierreel J, and its upper arm is connected with a link, 15, which extends to and is in connection with the shaft I', carrying the gears I I. To continually keep the roller-stud I3 on the lower arm of lever I4 in close contact with the cam 12, I employ a rod, 16, which is connected to A third disk, K3, is arranged and perp the other arm of the lever 1*, and extends; through a socket, i, on the frame of the press, 1

`and which rod 1i has a collar, "2 thereon,l which is subjected to the `action of a spring, j

Il, coiled around the rod I, and abutting, re- 5 theaction of the spring being in the proper direction to produce the desired result. Howeve'r, other means which would suggest themselves to askilled mechanic could be employed to eiect the same result.

'spectively, against the socket i6 andcollar fk,

Thefmeans for removing the printed sheet;

from the impression-cylinder B, retainingthe saine on the carrier-reel J, and releasing the said sheet at the proper moment from the carrier, consists of a set of grippers, M, Fig. 2, mounted upon a gripper-shaft, M', the said shaft-having bearings in the gear-wheel K and disk K3, which are-mounted on the said shaft. These grippers M are operated by a lever, M2, fulcrumed to the disk K3, which is subjected to the action of a suitable spring in the-ordinary manner, and is adapted to be engaged by a trip-cam, M3, secured to the receiving-table H, and also by a suitable cam, M, and the ends of these grippers impinge upon the edge of a `radial web, K4, extending from the spindle'a'nd across the reel, so as to clamp the edge of the paper between the grippers and the web Ki. To allow the use of such an arm or partition, the disks must necessarily be slotted. As before stated, the disks K2 K2 and disk K can rotate independently of the shaft I and the gears I I thereon. In other words, the carrier-reel J can rotate independently of the carriage; but when the printed sheet iS ready for delivery to the receiving-table, and during the linear motion ofthe reel, it is necessary that the carrier-reel should not rotate independently, but participate in the rotation of the gears I -I. For this purpose some locking device must be employed, and in the example shown in the drawings I have made use of the following: Upon the main shaft E of the press is secured a bevel-gear. N, which meshes into a similar gear, N,v situated upon a counter-shaft, N2, aligned at right angles to the former shaft, E, and which shaft has suitable bearings in the press-frame. This counter-shaft N2 has thereon acam, N3, which engages a roller-stud, n3, secured to one end of a rod, N", which rod is suitably bifurcated to straddle the shaft at this point, and the upper end of this rod N4 is connected to a lever, N5, which is fulcru'med at n to the press-frame, while its other end is provided with an inwardly-extending projection, at, which eugages with a pin, ne, upon one arm of a lever, N6, pivoted at or near its center to the gearwheel I. The lever N3 is provided with this inwardly-extending projection n* in order that when the reel-carriage moves forward in its linear motion toward the receiving-carriage H the said lever N5 will not interfere with its motion. As the carrier-reel is thus drawn forward by the link`15, the pin n" clears the projection n* ofthe lever N5. The lever N is subjected to the act-ion of a spring, nl, which constantly tends to keep the same in contact with the lever Niwhen opposite thereto. The pin n extends through a slot, n, Figs. 1 and 3, in the gear-wheel I, to allow the lever to swing about its fulcrum, and engages at the proper intervals with a catch, n, on the gearwheel K, thereby'automatically locking the two gears, and producing the desired result. When the roller-stud n3 on the rod N* is not engaged by the cam, the gears and the reel are locked, but when the said rod is so engaged by the cam N the lever N6 is raised, and the pin n is thrown clear of the catch ng, whereby the same is released from the cam, and the-designated parts can again rotate independently of each other.

The operation ofthe press isnow as follows: In the drawings the working parts of the press are shown in the position they will be in when the press has finished printing the sheets and the impression-cylinder is in such a position that the grippers Bz'thereof are ready to grasp the next sheet and a sheet is under the grippers of the `paper-carrier reel. When the main-shaft E now continues its motion in the direction of arrow l, the type-bed C moves toward the impression-cylinder -B in the direction of arrow IOO 2 marked thereon, but does not rotate theimpression-cylinder,since the latter is not rotated by the catch-lever F so as to bring its teeth in contact with the rack C until the shaft E has made one-half of a complete revolution, which fact is due to the contour of the cam FZ, and consequently the cylinder remains stationary until the bed has reached its extreme position on the opposite side of the impression-cylinder. During the semi-revolution of the main shaft and the traverse of the bed the hollow portion of the heart-cam I2 is brought toward the roller-stud I3, on the lever I, and,owing to the action of the spring I7, the upper arm ofthe lever ILis pushed outward in the direction indicated by arrow 3, carrying with it the carrierreel J, the gears I I of which engage and travel along the racks G G. Just before the carrierreel starts in its linear motion, the pin a of the lever Nis released from the cam N3 on the shaft N2, whereby the gears and the gear and disks of the carrier-reel are locked. The lever I, being moved outward from the impressioncylinder, carries the the carrier-reel therewith, the disks now rotating with the gear-wheels I I until both have reached the position indicated by dottted lines in Fig. l. During this traverse the grippers IWI on the shaft Mare opened by the lever M2 coming into contact with the spur or cam M3' on the receiving-table, so e that the end of the sheet is released, the sheet then falling printed face upward upon the delivery-table. On the remaining semirevolution ofthe main shaft E the carrier- 'reel J is returned to remains in its normal position in contact with the impression-cylinder. The carrier-reel and the reel-carriage gears I I are again unlocked, in order to allow the reel to rotate with the said impression-cylinder, and the type-bed moves toward its original position, as shown in the drawings, but in so doing it engages with the cogwheel B of the impression-cylinder, which has been previously sufficiently turnedby the action of the lever F2, and when in the position shown in the drawings the grippers B2 are again in position to grasp the sheet delivered thereto from the feedtable. Since the carrierreel J participates in the rotation of the impression-cylinder, the forward edge of the sheet printed during the preceding operation is grasped by the grippers M of the carrierreel J, which draw the same upon the carrierreel,whence it is delivered,as before described. Since only two disks, K K2, are used in the construction of the sheet-carrier, only the edges of the paper come in contact with thel said reel, and consequently the printed face is delivered unsoiled from the said reel to the receiving-table. As before stated, the sheet is held to the carrier-reel only along one of its edges, the lower edge of thevsheet being free; but the entire sheet holds itself closely around the disks of the said carrier-reel during the operation of delivering the sheet to the receiving-table, and the free end of the sheet does not `release itself from the carrierreel until it arrives at the proper position to fall upon the table.
