Abstract
415,471. Kinematograph apparatus. SHIRLOW, A. E., Flower Street, Caulfield, near Melbourne, and McDIARMID, T. B., 21, Burns Lane, Melbourne, Australia. Feb. 27, 1933, No. 5892. Convention date, March 3, 1932. [Class 97 (i).] Film-winding means comprises a flanged disc 3 supporting radially-arranged conical rollers 8 inclined upwards towards the centre of the disc, the spindles 7 of the rollers being provided with bevel pinions 10 meshing with a central bevel gear 11 driven from a prime mover ; the flange 4 of the disc has a slot through which the film passes over a sprocket to form a loop for projection, and the film returns to the rollers over a sprocket 29 at the centre of the disc, being turned on edge by them and wound against the inside of the film roll. The rollers 8 are surfaced with rubber or other resilient or yielding material, or are wholly made of such material. The spindles 7 are mounted in bearings 9, 6, respectively carried by the flange 4 and by a ring 5, and the spindle 12 of the bevel gear is carried by a bearing 13 within the ring 5 and is driven by a worm wheel 14 and worm on a spindle 16. The sprockets may be driven in unison with the rollers, each by means of a pinion on one of the spindles 7.
