Abstract

460,960. Kinematograph and like spool boxes. KOLB, O. K., and WENDER. E. J. June 4, 1935, Nos. 21275/35 and 32793/36. Divided out of 457,857, [Group XXXVIII]. [Class 97 (i)] A photographic sound - record film b is mounted on spools ea, eb within a casing f which is adapted to be clamped to the soundreproducing machine so that film driving spindles on the machine make driving engagement with the walls of conical apertures ga, gb in the spools. The film is led round rollers in the casing so that when a thickened portion near the ends of the film passes over a roller, a lever fe (or ff according to the direction of rotation) is actuated, breaking a circuit governing the film driving motor. The casing is positioned against a fixed abutment ha and clamped by an eccentric hb, which, in the locked position closes a switch s governing the operation of the reproducing machine. The film mav be held at its ends between adhesive tapes on the spools, the variation of thickness at the portions of the film held by the adhesive tapes being used to actuate the levers fe, ff. The casing may be removed and reversed or the levers fe, ff may actuate means for reversing the drive of the spools. Specification 457,857 is referred to in the second Provisional Specification.
