GEAR-LEVER DWELL-TYPE PAPER FEEDING MECHANISM

From crank 1, mounted on the main shaft of the stacker, motion is transmitted to connecting rod 2 which has slot d sliding along pin C of link 3. At the extreme positions of link 2, when the ends of slot d run up against pin C, rocker arm 3 is oscillated. This motion is transmitted through tie-rod 4 and link 5 with a pawl to ratchet wheel 6. Ratchet wheel 6 is mounted on the same shaft with gear 7 to which it is rigidly attached. From gear 7 motion is transmitted to upper conveyer a and to lower conveyer b. Connected to rocker arm 3 is ratchet-tooth rack 8 whose movement to the left can be stopped by latch 9. This latch is operated by the lowering of the friction rolls (not shown) when paper feed must be stopped. Spring 10 provides the return stroke of rocker arm 3.
