Patent GB-916654-A (GB)
Title: Improvements in or relating to kinematiographic projectors or cameras
IPC: G03B1/56
Filed: 1960-10-14
Abstract: 916,654. Film threading. LEITZ G.m.b.H., ERNST. Oct. 14, 1960 [Oct. 17, 1959], No. 35264/60. Class 97 (1). A film guide for self-threading kinematographic apparatus comprises two portions, relatively adjustable in a direction generally perpendicular to the direction of film travel through the guide to have either of two separations, one of said portions having a concave part, first encountered by the film during its threading, and a convex part, the curvatures of these parts being such that in the more open condition of the guide, when previously-threaded film would be running in free unrestrained loops, an attempt to thread film would bring the leading end first into contact with the said concave part at an acute angle to deflect it on to the leading slope of the convex part whereby it is further deflected away from the film gate. As shown in Fig. 1, for the initial threading of the film through the projector, the guide elements 7a and 7b, pivotable on pins 7c (by manual control via the lever system shown dotted), are close together so that a narrow channel is formed between the elements 7a and 7b from which the film emerges in a direction towards the film gate, the pressure-plate 9 of which is retracted from its normal holding position to allow free passage, of the film. Similar guides 10a, 10b bring the film towards a lower feed sprocket 11. Once the film is threaded, the guide elements 7a, 7b, 10a, 10b are separated to allow the film to loop freely. If, in this separated position of the guide elements one attemps to thread film through the projector (Fig. 3) the leading end of the film will encounter first the concave part of the lower guide element 7b at an acute angle a, then the leading slope of the convex part and will thereby be deflected upwards away from the film gate towards a portion 8a which it meets at an acute angle # to be deflected upwards through an aperture 15. This aperture is closed in the " closed " (threading) condition of the guide elements.
