Application filed March 23, 1911, Serial No. 616,525. Renewed February 18, 1912.

T 0 all whom it may concern:

Be it .known that 1, WILLIAM L. HAMIL- won, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Sheet-Delivery Mechanism for Printing-Presses and the Like, of which the following is a specification, and which is illustrated in the accompanying drawings, forming a part-thereof.

The invention relates tomechanisin for moving sheets of paper and the principal object. of the invention is to provide improved. means for effecting the discharge of printed sheets from printing press- In the accompanying drawings Figure 1 is a'vertical longitudinal sectional view of a rotary printing press having a sheet delivery mechanism embodying the invention associated with it, the supporting frame being omitted; Fig. 2 is a side elevation of the same, some of the parts being shown in section, and other parts being omitted; Fig. 3

is a perspective view illustrating a detail of delivery mechanism;

one end of the sheet of the sheet delivery Fig. 4 is a plan view mechanism, some of the parts being broken away; and Figs. 5, and 6, are diagrammatic views illustrating the operation of the sheet delivery mechanism.

Sheet delivery mechanism of a form provided by the; invention is illustrated in the drawings as being associated with a rotary prlnting press made the sub ect of Letters Patent on rotary printing presses, No.

This rotarv )rintin )I'QSS com )rises a Jair of oppositely turning cooperating cylinders with a printing or 10, 11, each provided D and with an impresplate surface as 14, 15,

Serial No. 749,274.

of the press sheets are delivered from the feed boards 18, 19, to the impression surfaces 16 17, of the cylinders 10, 11, respectively, 1n alternation, the sheets from the feed board 18 thereby receiving an impression from the printing surface 15 of the cylinder 11, and the sheets delivered from the feed board 19 receiving an impression from the plate surface 1% of the cylinder 10.

For effecting the relative turning of the two cylinders 10, 11', required for their cooperation in the manner just described, the two cylinders are equipped with intermeshing cam gears as 20, 21, Fig. 2. Each of these cam gears has circular portions 22, 23, equal in circumferential extentaiid having the same radius, respectively, as the printing and impression surfaces 14, 17, of the corresponding cylinder. The adjacent ends of the twocircular gear portions 22, 23, of each of the cam gears 20, 21, are connectedby oblique "ear portions, as 24, 25. If, therefore, one of the cylinders as 10 be continuously rotated at a uniform speed in the direction indicated by the arrow on Fig. 1, the other cylinder, as 11, will turn inthe opposite direction at a variable angular speed such that the surface speed of the impression surface 17 of the cylinder 11 will be uniform with that of the printing surface 15: of thecylinder 10during that part of each revolution when the surfaces 1a, 17, cooperate, and the surface speed of the printing surface 15 of the cylinder 11 will be uniform with that of the impression surface 16 of the cylinder 10, while these surfaces are cooperating.

For removing the printed sheets from the impression surfaces 16, 17, of the cylinders 10, 11, a pair of delivery cylinders 267- 7," .may beemployed. As shown,

one of these delivery cylinders cotiperates with each of and is rotated continuously with such cylinder, but in the opposite direction, as by the cngagement of a gear 28 mounted upon the spindle of the delivery cylinder with the corresponding cam gear 20 or 21. To provide for the movement of the delivery cylinders 26, 27, necessary for the engagement of the gears 28 with the several parts the corresponding cam-gear as 20, 21, each is journaled at its opposite ends in links as 29, 30, which are pivot-ally 15, and 16,

1 has longitudinal side framehung from a fixed support as at 31, 32. For swinging the links 29, 30,,eacl1 carries a cam roller 33, which rides upon a cam bearing surface 34, conforming in shape with the cylinders 10, 11, and gears 20, 21, and formed upon the rim of the corresponding cylinder 10, '11,=in accordance with the usual manner of providing the cylinders of printing presses with so-called bearers.

In carrying out the invention a reciprocable carriage 35 is provided for receiving the printed sheet-s discharged'by the deliv ery cylinders'26, 27. This carriage receives the sheets printed side up and retains them in that condition during the several movements of the sheets upon the' tables, here after described, and upon their discharge from the tables onto piles, as A and B, Fig. 1. The sheets which have received an im pression from the printing surface 14 of the cylinder 10, are deposited printed side up at A, and those that have received an impression from the printing surface 15 of the cylinder 11 are deposited printed side up at B.

As shown, the reciprocable carriage 35 members 36, 37, which are connected at intervals by a plurality of tie-rods 38. The side frame members 36, 37, each carry anti-friction rollers 39 and these rollers run upon suitable rails 40 fixed in the frame .(not shown) of the printing press. The carriage 35 is preferably given a complete movement in both directions during each revolution of the cylinders 10, 11. Any convenient mechanism may be employed for reciprocating the carriage. There is shown for this purpose a lever 41 which is pivoted intermediate its ends upon a fixed support, as at 42, and has its opposite ends connected, respectively, to a crank pin 44 turning with the cylinder 1.0, and to one of the side frame members.

. as 36, of the carriage 35, by links 43 and 45:

4.7, and 4s, 49,

Two sets of superimposed tape tables 46, are mounted in the carriage 35. Each of these tape tables is composed of a plurality of continuous tapes 50, which turn over rollslocated at the opposite ends of the table, the end rolls of the table 46 being designated 51, 52; those of the table 47 being designated 53, 54; and those of the tables 48 and 49 being designated, respectively, 55, 56, and 57, 58. Each of these rolls turns loosely upon a shaft,'as 59, 60, which extends between the side framemembers 36, 37, of the carriage 35. The tape tables'46, 47, 48 and 49, are thus longitudinally arranged in the carriage 35. The upper tables as 46, 48, and the lower tables as 47, 49, of the two sets, are preferably mounted at the same level and in longitudinal alinement. The adjacent or inner end rolls of the upper tables 46, 48, are spaced apart a. sufficient distance to permit the passage of tables 46 and 48.

pinion, as 64, 65, is also coaxially a sheet downwardly between them, whereas the tapes 50 of the two lower tables 47, 49, have a relative staggered arrangement, as is most clearly shown in Fig.4 of the drawings, and the inner end rolls 54, 57 of these two last mentioned tape tables are mounted upon a common shaft 60.

Provision is made for driving the tapes ing the movement of the carriage 35 in each direction, the tapes of the other tables then remaining stationary. Preferably the tapes of the upper table advance end of the carriage as it moves in each direction, are driven, and these tapes are so moved that the upper turns of the tapes travel backwardly in the carriage.

F or driving the tapes 50 a stationary gear rack 61 extends along one side of the machine preferably adjacent the corresponding supporting rail 40and a gear pinion as 62, 63, is coaxially mounted with one of the end rolls, as 51, 56, of each of the tape The gear pinions 62 and 63 turn loosely upon the shafts 59 and they mesh continuously with the gear rack 61 whereby they are reversely. rotated during the reciprocation of the carriage. A gear mounted with one of the end rolls as 53,58, of each of the tape tables 47 and 49. These-last mentioned gear pinions are preferably 'turne'dwith the gear pinions 62, 63, and in the same. direction. fected through the pinions 66, 67, each upon a stub shaft 68 secured to the side frame member 37 of the carriage 35, and meshes with one of the gear pinions 62, 63, and one of the gear pinions 64, 65. The gear pinions 62 and'65 turn the rolls 5l-and 58, respectively, during the movement of the carriage 35 in one direction, and the gear pinions 63 and 64 turn the rolls 56 and 53, respectively,

medium of two gear tion. For this purpose 62, 63, 64 and 65, and rolls 51, 56, 53 and 58, respectively,- wheels and pawls, as 69, 70, and 71, 72. A pawl is mounted upon the inside face As shown, this is'ef-.

of which is mounted 50 of the two upper tables 46, 48, and of the I two lower tables, 47, 49, alternately, the tapes of each lower table as 47, 49, ,being as 46, 48, adjacent the l duringthe movement of the carriage 35 in the other direc-- each of the gears I have cotiperatin'g ratchet,

of each of the gears 62 and'65, an oppositely facing'pawl 72 is similarly mounted upon each of the gears '63 and .64. The ratchet wheels; 69 and 71 are also oppositely formed. one of theratchet wheels 69 is mounted upon an end of each of the rolls 51 and 58 for cooperating with the pawl 70 mounted upon the adjacent gear 62 or 65, and one of the ratchet wheels 71 is mounted upon an end of each of the rolls 56 and for cooperating with the pawl '72 mounted upon the adjacent gear 63 or In the use of the sheet delivery"mechanism the reciprocation of the carriage is so timed with reference to the operation of the cylinders 10, 11, that a sheet as b or b Fig. 6 is deposited upon the tape table e6 by the delivery cylinder 26 h during each movement of the carriage 35=to the right, as viewed in Figs. 1 and 2, and a sheet as a or a Fig. 5 is deposited on the tape table 4:8 by the delivery cylinder 27 during each movement of the carriage 35 to the left. The movement of the tape of the tables is such that a sheet as Z) Fig. 6 will be passed from the table 46 downwardly through the space between the end rolls 52, 55, onto the tape table 49 during each movement of the carriage 35, to the left, and a sheet as a Fig. 5 will be passed from the upper table downwardly through the space between the rolls 52, 55, onto the lower table i7; during each movement of the carriage to the right. Similarly a sheet as a Fig. 5 will be passed from the table 4-7 to the pile A during each movement of the carriage to the right, and a sheet as b Fig. 6 will be passed from the table a9 onto the pile B during each movement of the carriage to the left. Each sheet delivered to one oi the lower tape tables as 47, 49, during the movement of the carriage 35 in one d'rection remains at. rest with its printed side up upon such table during the movement of the carriage 35 in the other dimotion and is not deposited upon the corresponding pile .A or 13 until the carriage again moves in the first mentioned direction. The delivery mechanism described thus pro vides time for the ink upon a printed sheetto set before it is disturbed by the deposit oi? another sheet upon it.

To insure the downward travel of the sheets through the space 52, 55, a i-shaped deflector 73, having curved sides, extends between .the side frame members 36 37, of the carriage 35 at about mid-position between the rolls 52, To

revent the sheets resting upon the tape tables 46, 4.8, from being disturbed by air currents duringthe reciprocation of the carriage 35 a stationary guard plate 7 '1 extends over the carriage between the delivery cyl inders 26, 27. i I p i Form rollers 75, Y6 ot-usual construction are provided for inking the plate surfaces 14 and 15, respectively. The sheets which are printed with ink supplied from the term rollers, 'i 5, are delivered upon pile A. The sheets printed with ink supplied from the term rollers '28 are delivered upon pile B.
