968, 099. Film scraper devices. H. NORDHOFF, and F. WINTZER. March 17, 1961 [March 24, 1960] No. 9927/61. Heading G2C. In a device for scraping the ends of film strips prior to splicing them together, the scraper means is reciprocable transversely to the film, and also movable as a whole under spring loading towards the film. In the form shown, the device comprises two parallel guide bars 3 (only one shown in Fig. 2) hinged at 2 to a base-plate 1. Between the bars 3 is mounted a carriage 10 carrying two scraper blades 13. The carriage slides between the guide bars, and is guided in its traverse by pins 11 which engage in slots 12 in the bars 3. The central part of the carriage 10 has a projection 10a extending upwardly into a recess 18 in the handle 19. A pin 20 in the handle passes through a vertical slot 15 in the part 10a, so that there is a limited amount of vertical play between carriage and handle. A curved blade spring 16 is also accommodated in the recess 18, its outer ends 17 bearing on the upper surface 10b of carriage 10. By pressing the handle downwards against the top of the guide bars 3 (from which it may be separated by a protecting plate 21), the only force transmitted to the carriage 10, and hence the scraper blades 13, is the uniform stress due to the spring 16. The handle is then slid forwards and backwards, so that the spring- urged scraper blades 13 engage against the ends of the film strips which are clamped between the pairs of plates 6, 7 and 8, 9.
