Abstract

12,411. Life Targets, Ltd., Harris, A. W., and Corbin, D. H. May 28. Kinematograph apparatus. - Relates to kinematograph shutters for target apparatus of the kind described in Specifications 24,329/09, 8241/10, 28,522/10, 29,083/11, 15,031/12, and 17,536/12, [all in Class 20(i), Buildings &c., Kinds &c. of]. The shutter is formed in two parts a, b; the part a is a sector of 120 degrees and is clamped on the driving-spindle c by a split sleeve c<1> and screws c<3>; the part b has two opposite sectors of about 60 degrees each, is mounted loosely on ball bearings, and is driven from the part a by ratchet teeth a<2> acting on taper-nosed spring plungers d so that it can overrun by its own momentum when the part a is stopped, thus allowing a longer time for arresting the film-operating mechanism. The large sector cuts off the light while the film is moved, and the small sector prevents flickering of the film.
