Abstract

1317556 Expanding pulley gears; securing pulleys on shafts MOLINS MACHINE CO Ltd 24 June 1970 [24 June 1969] 31794/69 Headings F2D and F2U An expanding pulley for variably driving the garniture tape of a cigarette or filter rod making machine comprises belt-engaging segments 18 slidable along radial slots in an annular body 16 and having pegs 28 engaging spiral slots 26 of a cam disc 24 turned to effect radial adjustment of the segments 18 in the slots, the assembly being clamped in any required setting by bolts 38. The cam disc 24 is adjustably turned by rotating a pinion 30, on a shaft 32, meshing on internal ring gears 34 formed in the cam disc 24, the shaft 32 having a square ended spanner engaging portion 36. The cam disc 24 has two sets of cam slots 26 alternately engaging alternate segments 18. The expanding pulley assembly is freely mounted on a driving shaft 10 and is connectible or disconnectible thereto by a coupling comprising a sleeve 41 slidably splined on the shaft 10 and having a disengageable toothed engagement 43 with the sleeve 44 bolted fast at 46 to the pulley body 16, the sleeve 41 being axially located on the shaft by a spring loaded ball detent 48 which may be locked in either the inner engaged or outer disengaged position of the sleeve 41 on the shaft by partial rotary movement of a surrounding ring formed with a shallow (locking) and a deep (releasing) detent recesses. The pulley may be manually rotated for test purposes by a wheel 64 fast with the pulley.
