Title: Apparatus for applying liquid intermittently to plane surfaces
IPC: G03D15/00
Filed: 1930-06-06
Abstract: 354,906. Coating cinematograph films &c. RODDE, A., 6, Rue Philippe de GÚrard, Paris. June 6, 1930, No. 17570. Convention date, June 8, 1929. [Class 140.] A film 1 or other material is moved step by step in the direction of< >the arrow, Fig. 2, and is tinted or coated with liquid by a drawing pen 11 which moves transversely to the film. The pen moves to and fro along a rocking lever 13 so that on the return stroke, with the lever 13 in the position shown in full lines in Fig. 3, the pen is out of contact with the film and is dipped at the end of the stroke into the supply well 12. The motions are derived from crank discs 4 by connecting rods 5 and crosshead 6. The pen is moved along the lever 3 by a link 9 connected with the crosshead 6. The lever 3 is rocked in one direction by a spring 14 and in the other by an arm 18 on the crosshead engaging alternately with the ends of a slot 15<1> in a rod 15 so as to bring the cam-shaped end 15<11> of the rod into or out of contact with a roller 19. If three colours are required the film may be fed so that the pen tints every third picture, the film being passed through three machines, or three times through the same machine, or the machine may comprise more than one tinting device. The pen is loaded by a movable weight 20 to prevent jumping. The film is wiped after each operation of the pen by a pad 21 on an arm 22 of the crosshead 6, and the wiping pad is itself wiped against a rotary pad 23 which is turned through a small angle at each stroke by a pawl on a second arm 25.
