Abstract
245,203. Palmer, A. S. Oct. 3, 1924. Reel and endless-web apparatus. - In apparatus in which changing colour effects appear on a picture, the colour screens are in the form of endless bands one or more of which moves transversely to the rest, and are semi-transparent, e.g. of silk, to allow light to pass through from a source L. Two bands are shown passing across one another at right angles behind the picture P<1>, P<2>, the horizontally moving band passing round the four sides of the casing on rollers B<1>, B<2>, and the vertically moving band passing round rollers A<1> - - A<4> so as itself to form behind the picture P<1>, P<2>, two contacting layers moving in opposite directions. The rollers B', B<2> may alternatively be arranged so that their band crosses the other between the rollers A<1> and A<2> and between the rollers A<3> and A<4>, thus giving two view faces. Further, the doubled band may pass round four sides of the casing. The bands may be driven continuously or intermittently by a motor, and may be synchronized, or be of different lengths or move at different speeds to delay repetition.
