VARIABLE $IZE-FLAT SHEET-DELIVERY MECHANISM.

T 0 all whom "it may concern.

Be it known that I, Howann M. Banana, a citizen of the. United States,and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Variable- Size Flat Sheet Delivery Mechanism, of which the following is a specification.

M y invention consists broadly in variable size fiat sheet delivery mechanism andmore particularly in mechanism arranged to deliver a collected roup of variable size sheets as they are fed from a suitable source such, for instance, asa rotary printing press, fiat on to a receiving board, utilizing sheet collecting and transfer cylinders,- a reciprocating carriage and endless feeding tapes.

The several parts of the mechanism to be hereinafter described are so arranged that they may be readily adjusted to operate upon sheets of variable sizes.

In the accompanying drawings I have represented a rotary printing press of the perfecting type, to which press variable size sheets are fed from a mechanism which will only be generally described herein as such mechanism forms the subject-matter of an application filed by me February 23, 1906, Serial No. 302,395 for variable size sheet cutting and feeding mechanism. I have also shown in connection with said printing press, a mechanism which is arranged to submit the variable size sheets as lhev are delivered-one by one from a suitable source such, for instance, as a rotary printing press, to a first fold and a second fold, then cutting the folded sheets into signatures and finally submitting each of the sections to a folding operation and delivering them in signatures to a. predetermined pointf Such mechanism will not be specifically described herein as .it forms the subject-matter of an application filed by meof even date herewith Serial No. 367,747, entitled Variable size sheet folding, cutting and delivering mechanism.

My present invention is devoted to the variable size flat sheet delivery mechanism as hercinbefore stated.

A practical embodiment ofvmy invention Specification of Letters Patent. Patented J 11118 Application filed April 12, 1907. Serial No. 367,748.

- The first plate cylinder is denoted by 1 'l he second plate cylinder is denoted by 3 and its impression cylinder bye. Variable size sheets are fed to the printing cylinders in the present instance by providing a ver tically adjust-able carriage 5 mounted in the 15} surface speeds through lobed gears 14, 15,

from the shaft 16 of the first impression cylinder. The second impression cylinder 1 is provided with two sets of grippers 18,,

19, which are arranged to transfer the advance edges of the sheets successively one at a time to the set of grippers 20 carried by the collecting cylinder 21' of myimproved flat sheet delivery mechanism. The shaft of this collecting cylinder 21 is denoted by 22 and it is mounted in suitable bearings in the side frames 6. The collecting cylinder 21 is provided with a tucking blade 23 which is arranged -to coact with a set of folding grippers2l on the transfer cylinder' 25 when the machine is used for folding, cutting and delivering variable size sheets. This folding mechanism is not used in connection with my present invention.

The box cam 26 which is used for floating the tucking blade 23 is rendered inoperative by removing the stud roller arm from its tucking blade. The cam 27 for controlling the outward movement of the tucking blade 23 is rendered inoperative by moving it out of the path of the stud roller 28 of said tucking blade as clearly shown in Fig. 15. The box cam 29 for controlling the floating of the tucking blade 241* on the transfer cylinder 25 is rendered inti perative by removing the truck roller arm fiiim its tuckingblade. The cam 29* for controlling the outward movenlent of the tucking blade 24* is rendered inoperative by moving it out of the plane of the stud roller 30 of said tucking hl adc as clearly shown in Fig. 16. The folding grippers 24 on the transfer cylinder 25 are opened by a stationary cam 24* but because of their cooperative tucking blade be ing inoperative, they 'are allowed to open and close without taking a sheet.

A set of grippers 31 is provided on the transfer cylinder 25, which grippers are arranged to receive a collected group of sheets from the grippers 20 on the collecting cylinder 21 and transfer the said collected group of sheets to the reciprocating sheet delivery carriage to be hereinafter described; The set of grippers 20 on the collecting cylinder 21 is rotatively adjustable by mounting the shaft 32 of said grippers in a rotativcly adjustable arm 33 mounted on the shaft 22 and provided with means 34 for clamping the grippers in the desired position to receive sheets of a predetermined length from the grippers 1S and 19 of the second impression cylinder 4-. The cam for opening these grippers 20 to receive sheets successively from the grippers 18 and 19 of the second iinpres sion cylinder 4, is denoted by 35, which cam is provided with an adjusting device 36 for bringing it into the desired position to engage the stud roller 37 and opening the grippers against the tension of the spring 38. A movable cam 38* is arranged in position to engage the stud roller 37 of the grippers 20 to open the grippers once in every predetermined number of revolutions of the collecting cylinder 21 for delivering a group of sheets from the collecting cylinder to the transfer cylinder The means which I have shown for throwing the movable cam into and out of operative position is constructed and arranged as follows The cam 38* is mounted to slide laterally on pins 39. A rock lever 40, 41 is pivoted at 42 and has its arm 40 connected to the cam 38* and its arm 41 engaged with a rod 43 bearing a stud roller 44 arranged to travel in the groove 45 of a box cam 46 mounted on'a rotary shaft 47 This rotary cam shaft 47 is driven from the shaft 22 of the collecting cylinder through a. train of gears .48, 48, 50, 51. A movable cam 52 is arranged in position to engage the truck roller 31* of the set of grippers 31 at the propentime to open the grippers to receive a collected group of sheets from the collecting cylinder 21 as follows. The cam' 52 is mounted'to slide laterally on pins 53, 54. A rock lever 55, 56, is pivoted at 57 and has its arm 55 connected to the cam 52 and its arm 56 engaged with a rod 58 having a stud roller 59 arranged to travel in the groove 60 of a box cam 61 fixed to rotate with the shaft l7. stationary cam 62 is arranged in position to engage the truck roller of the grippers fil at the proper time to open said grippers to permit the collected group of sheets to be transferred to the reciprocating delivery carriage. As the collected group of sheets is released from their grippers 31, it is delivered on toa plurality of stripping fingers 63 fixed to an adjustable shaft 64. Feeding pulleys 65 are mounted on a shaft 66 carried by arms 67 projecting from a shaft 68, which feeding pulleys 65 are held pressed against the periphery'of the transfer cylinder 25 by a spring 69. These feeding pulleys 65 insure the delivery of the advance edges of the collected group of sheets onto the stripping fingers 63. These stripping fingers 63 are raised out of position when the folding and cutting mechanism is not in use and lowered into position to receive the collected group of sheets from the transfer cylinder when the flat sheet delivery mechanism is in use, the means employed for such purpose being an arm 70 fixed to the shaft 6 1- and having a locking device 71 arranged to be brought into engagement with a socket; 72 on the side frame 6. l

The reciprocating delivery carriage for conveying the collected group of sheets from the transfer cylinder to the receiving board '73 comprises cross shafts 74, 75 and a lon itudinal spacing bar 76. These cross sha ts 74, 75, are provided with slides 77, 78, on

their ends arranged to travel on tracks 79, 80 fixed within said side frames. Sheet cari the transfer cylinder 25. This driving belt .82 leads forwardly from the pulley 83 and passes around a pulley92 on the cross shaft 75 of the carriage. From this point the belt leads rearwardly and passes around a pulley 93 supported by a bracket 94 depending from the slide 77 at one side of the carriage.

- From thence the belt 82 leads forwardly and around a driving clutch pulley 95 mounted on across shaft 96. After'passing around the pulley 95, the belt leads rearwardly and passes around the pulley 83 hereinbefore described. This arrangement of the driving belt permits the reciprocation of the carriage for bringing the collected group of sheets from the transfer cylinder to a point where the group of sheets maybe deposited upon the receivmggboard 73.

The reciprocation of the carriage and the intermittent movement of the belt 82 and the sheet carrying tapes 81 are imparted by mechanism such as that shown, described and claimed in United States Letters Patent No. 757,248 dated April 12, 1904 granted to me for improvements in sheet delivery mechanism for printing machines. A shortstate ment onl of the construction and operation of the said devices is therefore given herein.

The reciprocating movement of the fiat sheet delivery carriage is imparted through the following mechanism. The gear 48 on theshaft ofv t-he t-ransfer cylinder'meshes .with age'ar 98 onthe shaft 99 of the second folding cylinder not used herein. A pinion 100 onthe shaft 99 mesheswith a gear 101 on a cross shaft 102, which shaft passes,

through a stationary cam 103in which the truck roll 104 of a slide 105 is located, which slide 105 is fitted to reciprocate in an arm 106 fixed to rotate with the shaft 102. A rack 107'is mounted in a guide 108 fixed to the side frame 6, which rack isconnccted to bar 114 in position to engage the advance edges of the sheets as they are delivered on to the pile. -A longitudinally movable jogger 115 is provided with rearwardly ex- .tended rack bars 116 which are engaged 'with pinions 117 fast to a cross rock shaft 118. A rocking movement is imparted to the shaft 118 from the rotary shaft 102 by providing said shaft with a box cam 119 in which the truck roll 120 of a connecting rod 121 is located, this rod 121 havin its rear end supported on the shaft 102 an its front end connected to a crank 122'adjustably secured to the cross shaft 118 by a set screw 123. This crank 122 is shown in the present instance as a disk. The back jogger 115 may be adjusted to any desired position to accommodate it toVariable size sheets'by releasing the set screw 1% of the crank 122 and rotating the shaft 118 by hand to ad- Vance or withdraw the back jogger 115 until it is brought into the desired osition. The set screw 123 is then tightened to permit the cam 119 on the rotary shaft 102 to rock the same to impart a reciprocating movement to the back jogger.

The side joggers are denoted by 124 and are here shown as arranged in pairs. Pairs of parallel longitudinal bars 125, 126 form supports for the pairs of joggers and are themselves supported at their ends by car riages 127, 128 mounted on front and rear cross bars. 129, 130 supported by the side frames 6. Each of the pairs of side jogger-s are independently adjustable toward and away from the other pair by providing the front and rear carriages 1'27, 128 of each pair ofsaid side bars 125, 126 with gears 131, 132, carried by a hand shaft 133, the said gears meshing with racks 134, 135 in said front and rear cross bars 129, 130. These shafts133 are provided with suitable prank-handles 133*. The joggers 124 are -"a'djustable longitudinally of the machine along their supporting side bars 125, 126. Each of the joggers 124 is provided with a parallel movement by pivoting the shank 136 of the jogger to rocking arms 137, 138. Both of the side bars 126 have the arms 138 of the joggers fixed thereto so that when these bars are rocked the propcr movement is imparted to the joggers. These bars 126 are connected to rock together by providing the bar 126 at one side of the machine with a depending arm 139 and connecting it by a cross rod 140 with one of the arms 138 of the other bar. To permit the joggers to be adjusted toward and away from eachother, the cross rod 140 is provided with an elongated loop portion 141 and the arm 138 with Hvhich said rod 140 engages, is provided with a set screw 142 for clamping said arm to the rod 140 atany desired point along the loop portion 141. The rocking armi126 at one side of the machine has its movement imparted to it from the rock shaft 118 as follows. The said rock shaft 118 has a bevel gear 143 adjustably secured thereto by a set screw 144;, which bevel gear engages a bevel gear 145 on a stud shaft 146 supported in a bearing 147 carried by a bracket 148 secured to the side frame 6. This shaft 146 has fixed thereto a depending arm 149 which is connected to an arm 150 depending from the bar 1'26, through a.connecting rod 151. To permit the joggcrs to be adjusted laterally of the machine, the connecting rod 151 is provided with an elongated loop portion 152 and thearm 150 is provided with a set sired position along the loop portion 152. By loosening the said screw 144 of the bevel gear 143, the shaft 118 can be rotated by haiid to adjust the back jogger 115 without disturbing the adjustment of the side gers 124.

The flat sheet receiving board 73 is raised and lowered by hand and may be readily moved out ofposition when the required amount of sheets has been stacked thereon, by means of a truck.

The side frames of the receiving board 73 are denoted by 154 and the front and rear traction Wheels of the truck by 155. Transversepulley shafts 156, 157 are mounted in suitable hearings in the side frames 6 and the pulleys on the said shafts are denoted by 158, 159 respectively. Rear and front flexible connections 160, 161, are connected at their lower ends to the side frames 154 of the board and are arranged in position to be wound upon and unwound from the pulleys 158, 159. The pulley shafts 156, 157 are geared together through gears 162, 163, 164, 165. The means which I have shown for manually raising and lowering the receiving board comprises a gear 166 fast on the shaft 156, which gear meshes with a Worm 167.1ixed to a vertical hand shaft 168 supported in a bracket 169 secured to the side frame 6. This shaft 168 is provided with a suitable crank handle 170. i In operation, the rear and side joggers for the flat sheet receiving board are first adjusted to the proper positions for the particular sized sheets which are to be delivered flat on to the board. The stripping fingers 63 are then lowered into position to coact with the transfer cylinder The grippers on the collecting cylinder 21, the grippers 31 on the transfer cylinder and their cams are then adjusted with respect to each other for collecting and transferring sheets of a predetermined size from the second impression cylinder 4 to the flat sheet delivery carriage. The cams 27 and 29 are then moved out of position to operate the stud rolls 28 and 30 of the tucking blade and folding grippers on the cylinders 21 and 25, as these screw 153 for clamping the arm at any de- ,transfer cylinder '25. After the tour sheets have been delivered to the transfer cylinder, the grippers 31 are opened at the proper time to deliver the advance edges of the 001- I lccted group of four sheets on to the stripping fingers 63. The feeding pulleys 65 will,

by their coaction with the transfer cylinder 25, feed the collected group of four sheets on to the reciprocating flat sheet delivery carriage which at this time is at the limit of its rearward movement. The delivery car riagc tapes 81 which are driven at the same speed as the advancing collected group of sheets, willfeed the group of sheets along until it is delivered on to the carriage. The carriage will then be caused to move to the limit of its forward movement over the receiving board 73. reached, the carriage stops and reverses, the driving pulley 83 being at the same time thrown out of operation and the driving clutch pulley 95 is also held against reverse movement. This operation will allow the tapes to roll out from under the collectedgroup of sheets as the sheet delivery carriage returns to the limit of its rea ward movement, thus depositing the colle ed group of sheets on to the receiving board 73. The back and side joggers will bring the collected group of sheets into alinement with the previously deposited sheets on the sheet receiving board. Asthe pile of sheets increases in height on the receiving board, the board may be lowered nnt-iL'the required amount of sheets is stacked thereon. The board is lowered onto the truck and the flexible connections 160, 161, are then disconnected from the side frames 154, thus permitting the. truck with its load to be removed and a new board substituted. This new receiving board may be attached to the flexible connections 16 0, 161, and raised into position to receive the groups of sheets from the reciprocating delivery carriage.

\Vhat I claim is:

In a variable size flat sheet delivery mechanism, a collecting cylinder having a set of grippers thereon, a transfer cylinder having a set of grippers thereon, a recipro: eating flat sheet delivery carriage, cams arranged to operate the set of grippers on the collecting cylinder tocollect a plurality of sheets and deliver same to the transfer cylinder, cams arranged to operate the set of \Vhen this position is grippers on the transfer cylinder to receive as my invention,

the collected group of sheets from the collecting cylinder grippers and deliver said group to the delivery carriage, and means for adjusting the grippers and cums to suit variable size sheets.

In testimony, that I claim the foregoing I have signed my name in presence of two Witnesses, this 15th day of January 1907.
