DEVICE FOR SIDE REGISTERING SHEETS IN PRINTING OR SIMILAR MACHINES 2 Sheets-Sheet 2 .lm ewzan' WERNER KOC H By: 9- A Gf/v T6 DEVICE FOR SIDE REGISTERING SHEETS IN PRINTING. R SIMILAR MACHINES- Werner Koch, Offenbach: (Main), Hesse, Germany, assignor to Faber & Schleicher. Aktiengesellscliaft, Offenbach (Main), Germany, a firm Application January 4, 1951, SerialNo. 204,317 Claims priority, application Germany January; 10, 1950 4 Claims. (Cl. 271-59) My invention relates to devices for the side registering of sheets in printing or similar machines.

In printing machines the side registering of the sheets is operated by means of a so-called lateral stops or side gauges. A sufficient alinement or positioning will only be possible if the lateral mark. will be duly adjusted. This adjustment of the lateral mark essentially depends on the correct adjustment of, the so-called guide plate. On the one hand, the sheet of paper must not jamvbelow said guide plate andon the other hand, it has to be so guided during the feeding operation that even if consisting of thin paper any jamming between guide plate and stop or between stopand-feed plate will be avoided.

Prior-art devices of the said type are preferably provided with a guide plate screwed to the lateral stop in a position corresponding to the thickness of the paper, as the case may be. This operation, however, is inconvenient and troublesome in practice.

It is, therefore, an object of my invention to provide an improved device for sideways positioning of the sheets of paper which essentially facilitates the adjusting operation by swivably mounting the guide plate about an axis of rotation parallel with the feeding sense of the sheet path.

With this and other objects in view which will become apparent as the specification proceeds, my invention will be best understood by reference to the following specification and claims and the diagrammatic illustrations in the accompanying drawings, in which:

Figure 1 is a front view of the lateral mark or sideways positioning device;

Figure 2 is a side view of the same;

Figure 3 is an elevation of the guide plate and lateral stop; and

Figure 4 is a plan view of the same.

Similar letters refer to similar parts throughout the several views.

Referring now more specifically to the drawings, there is shown a housing 1 having a sheet feeding surface It: displaceably mounted upon both a traverse or cross bar 2 and a shaft 3. The lateral mark or sideways positioning device is adapted to be secured in any desired position by means of a set screw 4. A segment lever 5 is pivoted on a bolt 6. A spring 7 is adapted to advance a roller 8 to a drum cam 9 milled in a sleeve 10 which is driven by the shaft 3 by means of a sliding key 11. The sleeve 10 is at its sides fitted into the housing 1 so as to be driven by any lateral displacement of the mark. Moreover, there is fastened to the housing 1 a bolt 12 on which levers 13, 14 are pivoted. The lever 13 is a triple-cranked lever the lower arm I of which carries a roll 15 advancing to a drum cam 16 which is also milled into the sleeve 10. The lever arm II extending to the left according to Figure l carries a drop roller 17. The lever arm III extending to the upper side is connected to a spring 18 which can be put in tension by means of a threaded bushing 19 secured by a nut 20. After screwing out the bushing 19 the spring United States Patent" 0 2,730,362 Patented Jan. 10, 1956 18 isinterchangeable. The lever 14 is a double lever to the main part IV of which is fastened a block 21 being provided at its lower side with a guide plate 22 and a lateral stop or side gauge 23, adapted to penetrate into a slot 31 in the sheet feeding surface 1a of the machine housing, so that adjustments of the guide plate 22 in accordance with the thickness of the sheets will automatically also adjust the side gauge 23. A stop screw 24 located in the block 21 is adjustable with respect to the feed plate of the housing 1 and secured by a. lock nut 25. A spring 26 engaging the right arm V of the lever 14 urges the set screw 24 against said feed plate. The lateral fine adjusting is effected by means of adjusting nuts 29 which are screwed on a screw 27'. The traverse or screw 2 is secured in a holder 28 which is provided with the set screw 4. In Figures 3 and 4' the block 21 is illustrated once more, especially the arrangement of the stops 23 (Fig. 4).

The operation of the device for side registering sheets, described with reference to Figures 1 to 4, is as follows:

Under the action ofthe cam 16 the lever 13 is swivelled whilst the roll 17 is lifted. When the roll 17 has been disengaged from the segment lever 5 the arm II of lever 13 strikes against arm IV of the lever 14. and drives it upwardly against the tension of the spring 26 thereby causing the guide plate as well as the lateral stop to occupy the lifted position so that the sheet. of. paper can be ledinto the lateralmark or sideways positioning device. While the two levers 13 and 14 are thus rocked about their common shaft 12 the segment lever 5 moves to the left under the action of the cam 9. As soon as the sheet is duly positioned with respect to the front mark the roll 17, the guide plate 22, and the lateral stop 23 move downwardly to their working positions. Under the action of the spring 26 the lever 14 follows the lever 13 until the screw 24 strikes upon the feed plate of the housing 1. In this position the lever 14 and thence the guide plate and lateral stop are maintained by the tension of the spring 26. The lever 13 then continues to move under the action of the spring 18 until the roll will come into contact with the fed sheet. At this moment, the segment lever 5 begins to move to the right under the action of the cam 9, thus causing the sheet clamped intermediate roll and segment lever to be moved tothe right until its edge is stopped by the lateral stop 23. Then the segment slides away under the sheet until its motion ends. The pressing force of the roll 17 is conveniently controllable by adjusting the threaded bushing 19. As soon as sheets of another thickness are to be used the guide plate 22 is adjusted into its predetermined position by turning the stop screw 24. It is of no importance that in case of thicker sheets the front part of the guide plate will occupy a higher position than the part adjacent the lateral stop since thicker papers exert a sufficient resistance against jumping up. With thinner sheets of paper the guide plate extends in parallel to the feed plate.

The manner of using and applying the illustrative embodiment of my invention set forth above will be clear from the foregoing description. It is, of course, to be understood that my invention is not limited to the specific embodiment thereof here shown and described for purposes of illustration only.
