Abstract
470. Horak, J. Jan. 8, -1912, [Convention date]. Retouching.-Apparatus is described for automatically drawing the fine circular lines for retouching photographic negatives. The negative j is held in a box b between adjustable clamping-bars k in a holder g supported by four pins f by means of which the holder is given a continuous circular motion, while the pencil is held at any part of the negative. The holder g is held against the pins by springs h. The pins are eccentrically supported on disks d which are rotated by pedal or like driven gear including an endless moving chain, which directly drives the disks d. The box b is hinged to the base-plate, and is fitted with a shade i and a diffusing screen m.
