Abstract

218,737. Backhouse, H. T. April 10, 1923 Crank linkages.-The sheet-feeding bands of a printing-machine are driven by variable-speec gearing comprising two cranks or equivalent devices of unequal lengths rotatable about paralle axes, and coupled by a pin, stud, or other pro jection from the smaller crank in engagement with a radial, or substantially radial, slot or guide on the larger crank. In one form a crank-disc 1( is mounted on a shaft 12 in a gear-box 16, and is driven by bevel gearing from a shaft 22. A radial slot 18 in the disc 10 engages an anti friction roller 19 on a pin 17 mounted in a smalle: crank-disc 11 on a shaft 13 parallel to the shaft 12. The disc 11 is integral with a gear 23 which drives a shaft 28 connecting to the shaft for driving the feeding-bands &c. of the machine, which are given the required variable motion owing to the crank-drive. The slot 18 may be arranged to one side of the centre of disc 10, or it may be of curved form as shown in Fig. 5. The slot 18 may be replaced by upstanding ribs forming a guide of the same shape as the slot. The drive may be from the shaft 28 to the shaft 22.
