Abstract

190,813. Schoenenberg, W. Sept. 30, 1921. Web feeding and cutting arrangements; paper-shelves. - In apparatus supported on the papercarriage and comprising web feeding and cutting devices operated by moving a hand-lever in opposite directions, the hand-lever is arranged, after operating the cutting-device, to rock a frame for transferring the cut sheet to a pile supported by a shelf. In the apparatus shown, the hand-lever 20 on being moved forward operates a web-feeding roller 6, and on being moved rearward operates a vertically movable knife 54 and then operates a rocking frame 10 for transferring the sheet to a shelf 12. The web is folded and is supported by a tray detachably mounted on brackets 9 on the framework 1 of the apparatus. The web passes over a guide-roller 16 to the platen roller, and thence is lead over the feed-roller 6 and over a support 61 which is arranged underneath the knife, pressure-rollers 19 being arranged in contact with the feedroller. The hand-lever has a one-way connection with a pinion 32 gearing with a pinion 36 on the feed-roller. The connection consists of a ratchetwheel which engages a pawl on the pinion 32 and is provided on the hub with a pin engaging the front of a projection on the hub of the hand-lever, a returning-spring being arranged between the two hubs. The forward movement of the handlever is limited by an adjustable arm 26, in the path of a stop-screw 38 on the hand-lever. The arm is mounted on the spindle 22 of the handlever and is secured by passing a pin through one of a number of holes 41 in the arm. The knife is secured at the ends to blocks 54 sliding in guides 7 and connected by links 53 to arms 52 on a rock-shaft 51. An arm 50 on the rockshaft is provided with a pin 49 co-operating with a shoulder 63 formed in a slotted link 47 which is connected to a rocking arm 44 on the spindle 22 and is supported by a spring 64. On moving the hand-lever rearward, an arm 42 thereon engages an abutment 45 on the arm 44 and causes the link 47 to be drawn forward, the knife being thereby depressed. When the stroke of the knife is complete a screw 66 on one of the links 53 engages and depresses the link 47, thereby releasing the pin 49 and permitting springs 60 to return the knife to the normal position. The knife is provided at the front and back with vertically-movable web-clamping plates which are pressed downward by springs and normally depend below the edge of the knife. The plates press the web into contact with the support 61 when the knife descends, and the plates yield when the knife passes into a slot in the support. The frame 10 is secured to a rock-shaft 11 geared to a shaft 71 which is provided with an abutment 69 in the path of an arm 68 on the hand lever, the arm engaging the abutment at the end of the rearward movement of the hand-lever. The shaft 71 is provided with a returning-spring.
