Abstract

351,776. Paper - folding machines. GOSS PRINTING PRESS CO., 1535, South Paulina Street, Chicago, U.S.A.-(Assignees of Crafts, C. S. ; 645, North Lombard Avenue, Oak Park, Illinois, U.S.A.) July 23, 1930, No. 22234. Convention date, April 8. [Class 100 (ii).] In paper-folding apparatus more particularly for use with rotary printing-presses and of the kind in which tucker-blades carried by a cylinder 10 fold the sheets between a pair of rollers 17, 18, Fig. 1, one of the rollers has an eccentric mounting so that its distance from the other roller may be finely adjusted. Also, the means holding the rollers in their normal folding position is adapted to release the rollers if they become choked. The rollers 17, 18 are carried by arms 20, 21 pivoted at 23, 24 respectively to the main frame 16. Bolts 46 engaging slots 45 limit the extreme movements of the arms which are held with the rollers in operative position by pins 50 inserted in bushings in the arms and the frame 16. The pins 50 have parts of reduced diameter which are sheared when the rollers 17, 18 become choked and allow the arms 20, 21 to drop. A catch 53 engages a groove in each pin 50 to hold it in place and allow of its removal if the choke is insufficient to cause shearing. Each end of the roller 18 is eccentrically mounted in a bushing 30 rotatable in the arm 21 and each bushing has an operating arm 31 with a pointer 36 moving over a scale 37 so that the distance of the roller 18 from the roller 17 may be finely adjusted and also so that the rollers may be arranged out of parallel if desired. The roller 17 is resiliently mounted in the arms 20 and can be adjusted by means of screw-operated wedges 26 engaging the ends of the roller-carrying plungers 29. A gear wheel 60 on the cylinder 10 drives the roller 17 directly through a gear wheel 62, and the roller 18 indirectly through gear wheels 66 on a stub-shaft 64 engaging a gear wheel 67 on the roller. This drive always remains operative in spite of the movement of the rollers during the folding operation. Guides 40, Fig. 5, secured to the spindles 23, 24 by set-screws 41 are provided to ensure that large groups of sheets are retained on the folding- cylinder.
