ZENT, OF TROY, NEW YORK SHEET-REGISTER DEVICE Application filed August 1, 1929. Serial No. 382,768.

My invention pertains to the registering of sheets of paper upon which a printing opcration is to be performed, and relates more particularly to automatic registering devices for use in connection with presses of what is known as the Gordon type.

Attempts have been made from time to time to provide an efficient automatic sheet register for platen presses but no device has as yet beenv produced which has satisfied all the requirements of the case and especially so in the registering range or throw to synchronize with the various size sheets which may he handled by a certain size platen press.

it is the object of my invention, therefore to provide a certain, etlicient, and easily 1nanipulated device for registering the various sizes of sheets of paper by means of a multiple register arm device to synchronize the range of the throw with the range of the sheet size by thus devising a set travel are of the register fork of the device.

I have embodied my invention in several devices, a preferred and modified form of which I have chosen as satisfactorily indicating the various features thereof. These embodiments are illustrated in the accommnying drawings, in which Fig. 1 is a top plan View of my invention in modified form as applied to platen of a Gordon type printing press.

Like reference characters refer to like parts throughout the specifications and the several. figures of the accompanying draw- 5 ings.

The device as illustrated is applied to the platen of a press of the Gordon type. The platen 1 is provided with ordinary tympan retaining bails 2 and end stops 3 against which the sheets of paper are adapted to be successively placed. A side stop 4 is also provided against which the side of the sheet engages when the sheet is in proper register. Pivoted to the platen by pivot 7 b is the ordinary gripper bar 5 which carries the gripper fingers 6 the function of which is to retain the sheet in place during the printing operation and prevent the sheet from adhering to the type when the platen recedes. The above are among the ordinary equipments of a Gordon press.

An ordinary registering apparatus 7 hav ing lateral adjustment is attached to the platen 1 and has drive engagement with the gripper bar 5. In application of the ordinary registering apparatus 7 a registering arm is used to pull the sheets first against the end stops 3 and then against the side stop l. This registering arm is inserted in a pivotally mounted arm 8 which swings or pivots from pivot with an undercut slideway 9 longitudinally slotted for the insertion of the registering arm with its operative length readily adjusted as desired, to suit the various sizes of paper used. Arm 8 through its clamping member 9 is attached to member 22 which swings with it. t can be readily seen that as the registering arm length of adjustment is increased its travel are is increased when the registering arm is pivoted by the action of the registering apparatus 7 and therefore a restriction to minimum size of sheet which can be registered without interference of the registering arm with the end stops 3 is established, this being based on the the established maximum depth of travel of the sheet delivery fingers 10, as fragmentarily shown in Fig. 3, upon the platen 1 to grasp a printed sheet when ready for delivery.

The object of my invention is effected by providing means for an approximately set travel of the register arm to greatly increase 7 the sheet size registering range without interference with the end stops 3 as well as increasing the range of the delivery fingers 10 to grasp a printed sheet 11, increasing the throw of the registering arm on the mum size sheet to be printed by increasing the throw of the pivot arm 8, and decreasing the throw of the registering arm by means of a plural drive, on the minimum size sheet to be printed. As shown in Fig. 1 (and the same is true also of Figs. 3 and 5) I provided plural holes 13a to receive the screw 13 whereby lateral adjustment of member 15 (or 15a) is made possible.

Referring particularly to Figs. 3, 4, 5, 14, 15, 16, 17, 18 and 19, in which my invention is shown in preferred form an under slotted bracket 12, which is of inverted U-shape, at tached to the registering apparatus 7 by a screw 13 and having an under cut slideway 14 for the frame 15 as shown in Figs. 3 and 4: with operative length adjustment by the clamp screw 16. A registering arm 17 terminating in a paper fork 18 is swivel mounted to the stud 19 with a washer 20 and cotter pin 21. A drive arm 22 has operative length adjustment in undercut slideway 9 on the pivot arm 8 by the set screw 23 and is slideably mounted between the frame 15 and the registering arm 17 with its driving stud 24 engaging through the longitudinal slot 25 and being slid'eably held thereto by the washer 26 and the cotter pin 27.

Referring particularly to Figs. 1, 2, 6, 7 8, 9, 10, 11, 12 and 13, in which my invention is shown in modified form a frame 15a is mounted to the registering apparatus 7 by a clamping screw 13a'through the longitudinal frame slot 28, providing length adjustment. A registering arm 17 a terminating in a paper fork18a is swivelmounted to the stud 19a with a washer 20a and cotter pin 2161. A drive arm 22a with a normal positioning upset flange 29 has operative length adjustment in undercut slideway 9 on the pivot arm 8 by the set screw 23 and is slideably mounted between the frame 15a and the registering arm 17 a with its driving stud 24a engaging with the rim of the registering arm 17 a and slideably contacted thereto by the spring 30, which also holds the registering arm 17 a against the upset flange 29 when in normal position as shown in Fig. 1.

As has been shown longitudinal adjust ment of the registering arm 17 and drive arm 22 provides operative conformation to various sizes of sheets and positions of the sheets upon the platen and to meet the maximum range of the delivery fingers 10 to grasp a printed sheet ll from the platen 1, extent of throw of the registering arm 17 being ob tained by longitudinal adjustment of the drive arm 22 if desired. Various longitudinal sizes of the frame 15, registering arm 17 and drive arm 22 are obviously evident to also accommodate various sheet sizes and press platen sizes.

The operation of this device is as follows: When a sheet of paper is fed to the platen against the end stops 3 its front edge will enter between the tines of the fork 18 on the registering arm 17 as shown in Figs. 1, 3 and 5, the sheet being shown in full lines representing correct position against the end and side stops and the dotted lines designating its final position, the grippers being in open position as shown. As the gripper bar 5 actuates the registering apparatus 7 its pivot arm 8 actuates the drive arm 22 which in turn actuates the register arm 17 with a swinging motion due to the pivotal mounting of the members as hereinbefore described to correctly position the sheet against the end stops 3 and side stop 4 for printing, the fork 18 now being cleared of the sheet 11, all of which actions are shown in dotted lines in the drawings, the solid lines representing normal or sheet'receiving position.

It is also shown that the directional movement of the registering arm 17 is opposed to the directional movement of the drive arm 22 and that either right or left side stops 4 can be used by a choice of right or left movement registering apparatus 7.

The object of my invention is effected by providing means to reduce the lateral throw of the register arm so it will not contact its paper fork with the end stop 3 when registering small size. sheets and thereby adding to the efliciency of the press by reducing the minimum sheet size limitations that may be automatically registered and by the means shown permit the sheet to have an adjustment of sidewise location as well as being located high enough on the platen 1 to be within the maximum grasping range'of the delbrery fingers 3, all of which is accomplished without direct attachment to the printing surface of the platen 1 and thereby preserving the full extentof the platen printing contact surface.

This d vice is simple and particularly certain in operation, as well as providing a greater range of sizes of sheets to be printed and with ready adjustment to same, and quick and easy attachment to a Gordon or similar type press.
