DELIVERY MECHANISM FOR PRlNTlNG- PRESSES.

SFECIFICATION forming part of Letters Patent No. 643,178, dated February 13, 1900. Application filed May 15,1893. Renewed June 30, 1898. Serial No. 684,798. (No model.)

To all whom it may concern.-

Be it known that I, HENRY A. WIsE W001), a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and use ful Improvement in Delivery Mechanism for Printing-Presses, of which the following is a specification.

The aim of this invention is to produce a new and improved delivery mechanism for cylinder printing-presses which shall deliver 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 device described and claimed in this specification and illustrated in the accompanying four sheets of drawings, in which- Figure 1 is a side elevation of enough of a printing-press to illustrate the application of my invention. Fig. 2 is a plan of the same. Figs. 3 to 6, inclusive, are diagrammatic sectional views illustrating diiferent positions of the delivery mechanism while manipulating a sheet; and Fig. 7 is a detail of the gearing used to drive the tapes.

Referring to the drawings and in detail, 10 and 11 represent the usual side frames of a printing-machine, and in these frames the usual parts of the printing-press may be mounted, and these parts consist of the impression-cylinder 12, the reciprocating typebed 13, and the ink-table 14.

An inking device, as F, is arranged at the end of the press to give ink to the ink-table 14, and the ink from the ink-table 14 is carried to the form-rollers F, and the form is thereby inked.

The impression-cylinder 12 has two gears, as 16 and 17, mounted on the end thereof, the gear 17 meshing with an intermediate 18, and this latter with the gear 19, fastened upon the driving-shaft 20, which may have any of the usual driving means-as, for example, tight and loose pulleys R and R. Also fas tened on this driving-shaft 20 is a pinion 200, which meshes with and engages a gear 220, which gear 220 is formed on the periphery of a disk 22, which disk is mounted upon a shaft 221, which may be suitably mounted in the framing. Secured on this crank-disk 22 is a crank-pin 23, to which the pitman 24 is connected. This pitman or link 24 connects to a pivoted segment 25, which has gear-teeth, as 26, and which is mounted upon a shaft 27, and the connection between the pitman 24 and the segment 25 is made adjustable, as at 28. The shaft 27 is preferably carried across the press and two toothed sectors 25 are used. These two toothed sectors mesh with racks 29,which are formed or secured upon the lower ends of a reciprocating carriage 30, which is mounted so as to be capable of a reciprocating motion, preferably substantially parallel to the motion of the bed, upon suitable ways 15, formed on or secured to the main frames 10 and 11, as shown.

Upon one of the tie-rods, as 40, which connect the side frames 30, are mounted a number of arms 500, which carry small shafts or studs 31, which studs 31 carry tape-pulleys 32, around which tapes 33 run, and means, as suitable screws or pins, are provided whereby these arms are secured to the shaft 40, whereby by turning or setting the shaft in the frames or by turning and setting the arms 500 on the shaft the tension of the tapes 33 can be regulated. A shaft 34 is journaled in the right-hand ends of. the carriage-frames 30 and carries tape-pulleys 35, around which the endless tapes 33 are passed. The shaft 34 is preferably arranged lower than the studs 31, so that the tapes 33 will. stand upon an in-' cline.

Meshing with the gear 16 is a small pinion 42, which is mounted upon a shaft 420,which is journaled in the main frames 10 and 11, as shown, and mounted on this shaft 420 is a small gear or pinion 90, which meshes with a gear 92, secured upon a stud fastened in the frame 10, and also turning with this gear 92 is a bevel-gear 43, which engages with and drives a bevel-gear 44, secured upon a shaft 49, which shaft 49 is journaled in a bearing 491, projecting from the frame 10, and in a bearing46, projecting from one of the sliding carriage-frames, as shown. This shaft 49 is slotted, as at 490, and lies in a suitable trough or partial journal 50, extending from one of the frames 30 of the carriage, whereby the same will be steadied and nicely carried. Fit

ting upon this shaft 49 is a bevel-gear 47, which has a projecting hub 45, which is carried through the bearing 46 and which has secured upon the other end thereof a collar 470, which collar 470 may be fastened to the hub 45 by a suitable set-screw, as 471. The bevel-gear carries a suitable key 472, which fits in the slot 490 of the shaft 49. It will be seen that by this construction as the carriage moves forward and backward the bevel-gear 47 will travel forward and backward therewith, but still will be driven from the shaft 49, the shoulder 450 and the collar 470 keeping the bevel-gear fixed relatively to the bracket or hearing 46.

The bevel-gear 47 meshes with and drives a bevel-gear 48, which is mounted upon a short shaft which is mounted in a small bracket 480, carried by the frame 30, and on the inner end of this shaft is mounted a pulley 36, which is setin line with a pulley 38, fastened upon the shaft 34, and between which pulleys a belt 37 is arranged. By this means it will be seen that the shaft 34 is positively driven and that thereby the tapes 33 are driven and are moving at all times, no matter what the position or what the speed of the carriage 30 is.

Thetwo frames 30 of the reciprocating carriage are tied together by the shafts or braces 39, 40, and 41.

A suitable receiving-table K is arranged on the front of the press, as shown, and has suitable pivoted stops L and rear stops M, and the sheets S will be ultimately laid upon this table.

The impression-cylinder 12 carries a set of grippers G, which manipulate the sheet in the usual manner, and coacting with these grippers to deliver the sheet from the cylinder onto the set of moving tapes are the stripperfingers 51, which are mounted upon the shaft 511 and which have extending strippers 510, which are adapted to project between the tape-pulleys 32.

The gearing between the impression-cylinder and the crank-disk 22 is so proportioned that the crank-disk 22 will turn once for each two revolutions of the impression-cylinder, the particular device under consideration being the ordinary two revolution cylinderpress, the operation of which is well understood, the impression-cylinder making one revolution in contact with the type-bed on its forward movement and being raised so as to make the next movement clear of the type-.

bed as the latter makes its retrograde or return movement. By this means the reciprocating carriage will make one complete forward-and-backward reciprocation for each two revolutions of the impression-cylinder. Also it will be seen that the reciprocating carriage is driven through a crank mechanism whereby its movement will be at each reversal gradually retarded, stopped, and accelerated in the opposite direction, which is useful in connection with the device, as hereinafter described.

Referring now to the diagrams, the operation of my improved delivery mechanism will be described. In Fig. 3 a sheet S is shown as just being taken by the grippers G onto the impression-cylinder. In Fig. 4 the impression-cylinder is shown as having made a half-turn and the head of the sheet brought into printing contact with the form upon the bed. In Fig. 5 the impression-cylinder is shown as having made another half-revolution and the grippers G as just open and the strippers 51 acting to strip the sheet from the impression-cylinder and guide the same under the running tapes 33. In this position of the parts the carriage 30 has not quite reached its extreme left-hand position, but is still moving to the left and is being gradually brought to a state of rest. Now during the next half-revolution of the impression-cylinder 12 the sheet S will be stripped from the impression-cylinder and will be guided by the

strippers

51 and 510 down onto the continuously-running'tapes 33 and the sheet will be nicely fed onto these tapes while the carriage is reversing and starting again to the right, so that the sheet S will be largely upon the tapes 33 when the carriage 30 has moved partially to the right, as shown in Fig. 6. Now during the next half-revolution of the impression-cylinder the carriage will move to the right, the sheet S all the time advancing on the running tapes, and the sheet will commenceto be delivered, as shown in Fig. 3, by the sheet S upon the running tapes. The sheet will be delivered by the action of the running tapes 33 and by the action of the carriage, which in its left-hand movement will withdraw the tapes from under the sheet. It will also be noted that as the carriage is moved forward with the sheet upon the same the sheet will be gradually forced forward toward the forward end of the tapes and will come slightly beyond the pulleys 35 when the carriage reaches its right-hand position, so that the delivery of the sheet onto the receiving-table can accurately and easily commence. It will be seen that -both the sets of tape-pulleys which carry the tapes, being nicely guided from the impression-cylinder onto the set of running tapes. Thus this set of bodily-moving continuously-running tapes driven forward and backward by a crank mechanism constitutes a very nice, simple,

and efficient mechanism for delivering the sheet printed side up without grippers and without contact of the printed surface of the sheet with any part.

It is an important point to make the set of continuously-running tapes inclined downward relatively to the forward movement of the sheet, whereby as the carriage moves forward with the sheet thereupon the pressure of the air will tend to keep the sheet on the tapes, but whereby when the carriage moves back the air-pressure will tend to help the sheet move off of the tapes.

Of course this delivery mechanism can be used in connection with any cylinder printing-press, no matter whether the same is a single or multi revolution press or Whether the same is a single or double cylinder. It will also be noted that the sheet is delivered in full sightwithout the use of grippers and lies printed side uppermost when finally delivered.

The details of the invention herein 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 myinvention, what I claim, and desire to secure by Letters Patent, is

1. The combination of the impression-cylinder and reciprocating form-bed, a set of tapes onto which the sheet passes from the impression-cylinder, means for continuously driving the tapes, and means for reciprocating the set of tapes bodily forward and backward relatively to the impression-cylinder and parallel to the bed to deliver the sheet, substantially as described.

2. The combination in a printing-press of the impression-cylinder, a carriage fitted to slide in ways on the printing-press frame, a

set of tapes mounted in said carriage, means for continuously driving said tapes, means for reciprocating said carriage to deliver the sheet, and means for directing the sheet from the impression-cylinder onto the tapes, sub stantially as described.

3. In a delivery apparatus, the combination of a set of strippers, a series of tapes adapted in one position to intermesh with said set of strippers, means for reciprocating said series of tapes bodily to and from said strippers, and means for actuating said tapes so that the same will deliver the sheet, substantially as described.

4. The combination of the impression-cylinder, a reciprocating carriagecarrying two sets of tape-pulleys, a set of tapes carried around said pulleys, means for driving said tapes continuously in one direction, means for directing the sheet from the impressioncylinder onto the tapes, and a mechanism for reciprocating the carriage so that the tapes will be bodily moved forward and backward relatively to the impression-cylinder to deliver the sheet, substantially as described.

5. The combination of the impression-cylinder, stripper-fingers coacting therewith to strip the printed sheet therefrom, a reciprocating carriage, a set of continuously-driven tapes arranged entirely within said carriage, and a crank mechanism for reciprocating said carriage, substantially as described.

6. The combination of the impression-cylinder, a reciprocating carriage having a set of continuously-driven tapes arranged therein, means for directing a sheet from the impression-cylinder onto these tapes, and means for continuously driving these tapes, consisting of a keyed shaft mounted parallel with the movement of the reciprocating carriage, gearing for rotating this shaft, a bevel-gear carried by the carriage engaging this shaft by means of a suitable key, and connections whereby this bevel-gear will continuously drive the tapes, substantially as described.

'7. In a delivery mechanism for cylinder printing-presses, the combination of a reciprocating carriage, a set of continuously-driven tapes mounted completely within said carriage, and guides for directing the sheet from the impression-cylinder onto the set of running tapes, the set of tapes being inclined downward relatively to the forward movement of the sheet, substantially as described.
