SPECIFICATION forming part of Letters Patent No. 516,386, dated March 13, 1894.

Application filed May 23,1893. Serial 110.475.287- (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY A. WISE WOOD, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvement in Printing-Machines,of which the following is a specification. I

The aim of this invention is to produce a new and improved delivery mechanism for [0 cyl nder printing presses, and especially one which shalldeliver the printed sheets printed side uppermost, always in full sight, without contact of the printed surface with any part, and without the use of grippers.

To this end, the invention consists of the devlce described and claimed in this specification, andillustrated in the accompanying drawings, in which Figure 1 is a side elevation of a printing press illustrating my invention, Fig. 2 is a View similar to Fig. 1, the traveling carriage belng in its opposite position. Fig. 3 is a plan of my improved delivery mechanism, and Figs. 4 to 7 inclusive are diagrammatic views 2 5 illustrating the different positions of the delivery mechanism while manipulating a sheet.

My invention, broadly speaking, consists of two sets of intermeshing tapes, one set of which is bodily stationary, and the other set of which is bodily moved so as to carry the sheet forward and deliver the same upon the delivery table or delivery device; and the set of bodily movable tapes is preferably what a lower speed than the speed of the statlonary tapes, for a purpose hereinafter described.

Referring to the drawings, and in detail, A Arepresent the usual side frames of the press, 1n which the parts are mounted in any of the 0 usual manners.

B B represent the usual frames, which carry the shaft 0 of the impression cylinder D, which frames B B are so operated that the impression cylinder will be in contact with 4 5 the bed on the printing movementof the same,

, guide-ways E, as shown, and moving on these guide-ways E is a suitable carriage F, which carries the set of bodily movable tapes.

Arranged at the end of the press is the delivery table, or box G, which is held by suitable supports g on the frames E, as shown, and at the end of this delivery table, I preferably arrange stops g, of any of the usual characters.

Arranged on the top of the traveling carriage F are a set of guides or shields H which are held in place by any suitable adjusting means, as h to shafts 48 secured between the frames of the carriage, as shown.

A set of the usual stripper-fingers I is arranged to operate in connection with the impression cylinder D, as shown, and the impression cylinder D is arranged to carry the usual set of gripper-fingers N, which manipulate the sheet on the cylinder.

Extending from the frames B are arms or hangers 10, in which hangers 10 is journaled 7o the shaft 11, as shown. This-shaft 11 may, be positively driven from the impression cyliuder by means of a gear 14 secured to the back end of the impression cylinder, as shown in Fig. 3, by means of a suitableintermediate 13, and a gear 12 secured upon the shaft 11. Arranged on this shaft 11 are suitable tapepulleys 15, as shown, around which run tapes.

0n the frames Act the press, are also arranged hangers 17, in which is journaled a a shaft 18, which carries tape-pulleys 1-9 opposite the tape-pulleys 15, and around which the tapes '16 pass. It will be seen that this set of tapes 16 is thus bodily stationary, and that the same is preferably so arranged that the tapes will travel at thesame speed as the peripheral speed of the impression cylinder D; and by means of the usual stripper-fingers I, which may be actuated in any of the usual manners, the sheet will run oif the im- 0 pression cylinder D onto these tapes.

J ournaled in the frames of the carriage F is a shaft 20, which carries tape-pulleys 21, and running around which tape-pulleys 21 are the tapes 22. These tapes 22 pass to tape pulleys 23 mounted on a shaft 24, which is journaled in extensions 25 from the carriage frames F. It will be seen that the tapes 16 and 22 are intermeshed so that the tapes 22 can be moved forward and backtoo ward without interfering with the tapes 16. Also it will be seen that the tapes 16 are set meshes.

on a slight incline, and that the tapes 22 are arranged in a horizontal position, whereby, when the bodily movable tapes 22 are moved up close to the impression cylinder, the head of the bodily movable tapes that is nearest to the impression cylinder will be below the tapes 16, as shown in Fig. 4.. These bodily movable tapes are preferably positively dr ven, but at a slower speed than the tapes 16, and one convenient way to drive these tapes is by means of a gear 26 fastened on the front end of the shaft 11, which meshes with and drives a gear 27 mounted on a stud secured in the front bearing 10.

. Journaled in a suitable hanger 28 projectmg from the front bracket 10, and in a hanger 29 projecting from the front bracket 17 is a shaft 30. This shaft 30 is driven from the gear 27 by means of the bevel gears 31 and 32, as shown. The shaft 30 is keyed or slotted, as at 34, as shown, and fitting on this shaft, so, as to nicely slide on the same, is the bevel gear 36, which has a collar 33, as shown, and fitting between the gear and the collar is a pro ecting yoke 35, extending out from the carriage F, as shown. The bevel gear 36 meshes with and drives a bevel gear 37 secured on the shaft 20, as shown. By this means, it will be seen that as the carriage moves back and forth, the bevel gear 36 will be slid back and forth on the shaft 30; but that by this means, the shaft 20 will be always positively turned at the same speed with the shaft 11, or slightly less, depending upon the reduction in the gearing, before described. The pulleys 21 and 23 are made smaller than the pulleys 15 and 19; and the whole is so arranged that the speed of the tapes 22 will be approximately about onehalf the speed of the tapes 16. A shaft 38 is mounted in bearings carried by the frames A, and carries two gears 39, which mesh into racks 40 secured to the under side of the carriage frames, as shown. Also secured on this shaft 38, on the front side thereof, is a pin- 1011 457 into which pinion 47, the segment 41 This segment 41 is pivoted as at 42.

43 represents a shaft, which is mounted in the framing of the machine in any desired manner, and is preferably driven by any suitable gearing, not necessary here to describe, so as to turn once for each two revolutions of the impression cylinder D, if my invention is applied to the ordinary two revolution cylinder printing press. This shaft 43 carries a disk 4st, which disk 44 has a crank-pin 45, which connects by pitmen 46 to a crank-pin 47, carried by the segment 41. By this means,

the carriage F will be reciprocated forward and backward.

The operation of my improved device can be followed from the diagrammatic figures.

In Fig. 4, the sheet S is shown as just being stripped off of the impression cylinder, In

and as running out on to the tapes 16.

this position of the parts, the carriage F is arranged so as to be approximately at ts right-hand position.

In Fig. 5, the impression cylinder is supposed to have made half a revolution, and the sheet S to be now entirely upon the tapes l6; and it will be noted that the tapes 22 have been moved forward so that the front end of the sheet will rest partially upon these tapes 22, as shown.

In Fig. 6, the impression cylinder is supposed to have made another half revolution, and to have taken a second sheet S down on the same, as shown, the first sheet S 1n the meantime having been carried forward on the tapes 22, which tapes 22 are also moving in a direction to force the sheet forward. This will cause the sheet S to run off of the tapes 22 around the tape pulleys 23 down on to the table G, as shown. Now, during the next half revolution of the impression cylinder, the carriage F will move backward, and the tapes 22 will be gradually peeled away from under the sheet S, and the sheet S will be allowed to drop on the delivery table, as shown. I preferably drive the carriage F by a crank, as before described, and this crank gives a very nice and appropriate action to the carriage, in that the same will start up gradually while the sheet first runs on to the tapes 22, and in that the same will start back gradually when the tapes commence to peel from under the sheet. This will keep the sheet S firmly against the stop g, and will nicely and correctly deliver the sheet printed side uppermost on the table G. Of course, any other suitable mechanism, as a cam could be used, if desired, to actuate the carriage F. The guard or shield II placed above the tapes 22, will prevent the sheet from being displaced, or from curling up during its forward motion.

By my improved device, the sheet will be delivered from the ordinary printing press, printed side up, without the use of grippers, and without the contact of the printing surface with any of the parts.

My invention, of course, is applicable to any form of cylinder printing press, whether the same is a single or multi-revolution press, or whether the same has one or more cylinders, or whether the cylinder oscillates.

The details of the invention herein shown and described, may be greatly varied by a skilled mechanic without departing from the scope of my invention as expressed in the claims.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination in a delivery mechanism of two sets of tapes, on to one set of which the sheet first passes, the second set intermeshing with the first set, and taking the sheet from the first set, and delivering-the same, the
