SHEET-DELIVERY APPARATUS FOR PRINTING-MACHINES.

SPECIPICATIONforming part of Letters Patent No. 404,350, dated May 28, 1889.

Application filed September 20, 1888. Serial No. 285,880. (No model.) i

To all whom it may concern;

Be it known that I, GEORGE P. FENNER, a 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 for Printing-Machines, of which the following is a specification.

This invention relates to an improvement type-bed or type-cylinder, and B an impres.

sion-cylinder. A sheet being fed from the feed-board C is taken by the gripper D and carried between the cylinders A B. After being thus printed the sheet passes to the delivery traveler or tapes F. A stripping finger or fingers, E, actuated by an arm, I, and cam K, strip the printed sheet from the impression cylinder and cause said sheet to pass to the traveler F. Gears L are shown adapted to actuate the cam K. The traveler or tapes F are carried by rollers G H. The roller G is provided with a gear, 2', engaging the gear h, on the shaft of which is loosely mounted the gear m, carrying the pawl l. WVhen said wheel 0% moves in one direction, the pawl Z glides over the teeth of the wheel is without engaging said teeth or moving said wheel 7;. Said wheel 7: is fixed to the wheel h, or to its shaft, and when the wheel on moves in the opposite direction said pawl Z engages the teeth of the wheel and rotates said wheel is, and the gears 7L 2' are then rotated so as to turn the roller G and move the traveler F in the direction of arrow 1. A clutch-connection is thus formed for causing the traveler F to move at times and allowing said traVelerF to be at rest at other times. The gear at is oscillated by the rack-bar n, actuated by a crank-pin, e, or equivalent device, receiving motion from a suitable part of the machine as, for example, from the type-bed A or its gear-wheel c, Fig. 2. An arm or pin, 0, keeps the rack-bar in gear with the gear m. The actuation of the traveler F is so timegl that when said traveler is to deliver a printed sheet to the carriage M said traveler is moved in the direction of arrow 1; but when a sheet has been delivered by the traveler F to the carriage M said traveler remains for a time at rest.

The carriage M has rollers N O, supporting a traveler or tapes, P. On the shaftof the roller 0 is loosely mounted a gear-wheel, Q. A toothed wheel, R, is firmly secured to the shaft of the roller 0, and a pawl, S, is secured to the gear-wheel Q, so that a clutch-connection is formed between the gear-wheel Q and the roller 0. WVhen the gear-wheel rotates in one direction, the pawl S glides over the teeth of the wheel R without turning said wheel R or the roller 0; but when the gear-wheel rotates in the opposite direction the pawl S engages the teeth of the wheel R and rotates said wheel and the roller 0 and imparts motion to the traveler or tapes P.

A rack, T, is applied or fixed to the apparatus so as to engage the gear-wheel Q. The carriage M has a rack, U, engaging the gearwheel V. Two gear-wheels, V, Fig. 2, are shown zfdapted to engage two rack sone at each side of the carriage M; but one gearwheel, V, and one rack, U, might be made to answer. The gear-wheels V are oscillated by a gear-wheel, W, and rack-bar X, jointed or connected at Z to a crank, Y, or equivalent mechanism, such as a cam. The crank Y imparts an oscillating or reciprocating motion to the rack-bar, and a pin or arm, a, fixed to the press or machine holds the rack-bar in gear with the wheel WV.

The operation of the device is as follows: A sheet having been printed, said sheet is passed from the cylinder B to the traveler or tapes F, which are actuated at the proper time by the clutch-connection to carry said sheet, toward the carriage M and deposit said sheet on said carriage. The motion of the carriage is such that it is under the traveler or tapes and about to begin its forward movement at the time the head of the sheet passes off the traveler or tapes. Said carriage M, moving in the same direction as the sheet, receives the sheet from the traveler or tapes and conveys it over the receiving-table. The carriage M then moves backward or toward the cylinder B, and during this motion of the carriage the clutch-connection rotates the roller 0, so as to impart a progressive movement to the traveler or tapes P-that is, to move that portion of the carriage-tapes which carries the sheet toward the receivin g-table b. The sheet resting on the tapes P is by this progressive movement of the tapes caused to move off the carriage M to the receiving-table 1). During the forward motion of the carriage M away from the cylinder B the clutch-connection allows the roller 0 and traveler P to remain at rest.

Suitable gears, e (Z, Fig. 2, convey motion between the cylinders A 13. The carriage M is supported by ways f and rollers g, Fig. 2, so that said carriage can be readily reciprocated by the rack-bar X.

I do not herein broadly claim the combi nation, with an impression-cylinder, a delivery apparatus, and a receiving-table, of a reciprocating carriage positively moved in both directions and provided with a traveler or tapes having a progressive movement during the return movement of the carriage, as such constitutes the subject-matter of my application for Letters Patent filed September 20, 1888, Serial No. 285,878; nor do I herein broadly claim the combination, with an impression-cylinder and a receiving-table, of a continuously moving delivery traveler or tapes and a reciprocating carriage on which the printed sheet is deposited by the delivery-tapes, as such constitutes the subject-matter of my application for Letters Patent filed September 20, 1888, Serial No. 285,879.

That I claim as new, and desire to secure by Letters Patent, is-

' 1. The combination, with an impressioncylinder and a receiving-table, of an intermittently-moving delivery traveler or tapes, and

a a reciprocating carriage on which the printed sheet is deposited by the delivery-tapes, subf. stantially as described.

2. The combination, with an impressioncylinder, a receiving-table, and delivery traveler or tapes, of a reciprocating carriage on which the printed sheet is deposited by the delivery-tapes, and a rack and clutch connection for imparting an intermittent motion to the delivery traveler, substantially as described.

3. The combination, with an impressioncylinder, a receiving-table, and a reciprocating carriage, of a delivery traveler or tapes for delivering the printed sheet to the carriage, said delivery-traveler being actuated while a sheet is being delivered to the carriage, but being motionless when a sheet has been dolivered to the carriage, substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence of two sub scribing witnesses.

GEORGE P. FENNER. [L.S.]
