One-Shot Oiling System insures positive lubrication to all bearings as required, eliminating possibility of failure, as on previous models. Oil is filtered, thus insuring a clean supply in sufficient quantity at all times. wm Intermittent Oil System prevents leakage on operating side. Excess oil overflows on drive side. Reservoir can be refilled from either side. Oil cushion under pressure between leant ring and star wheel permits closer tolerance and shock absorptimn, insuring longer wear, vibration reduction and increased steadiness. Automatic Fire Shutter Safety Trip provides positive protection against aperture fire by automatically cutting off the light from the film by releasing the fire shutter when film remains stationary before aperture plate. Film G, nil, stantly removed, assuring easier accessibility for cleaning and adjustment. Contrast this construction with previous models. See close-ups of gate and trap; also, see removal of trap. Ovottlno Drive dear* revolving on fixed studs insure longer life and simplify maintenance. This type gear places pressure of operation where it Cantos least wear.

Gate wobble has been eliminated, regardless of length of service, by interaction of four parallel opposing surfaces. The gate is controlled by a flat-sided guide stud, with adjustments for wear.

Newly designed contraction of blade and curved vein draw the air acktcard from aperture and pass it around oute of mechanism, insuring much cooler film path than was possible heretofore. Improved Film Gate. The increased length of the Pressure Pad combination, together with the Spiral Spring and Adjustable Tension devices, insures that the film wilt be held in the proper position against the Film Trap with the least amount of tension necessary for the various types of film that may be supplied: namely, oil and shrunk film, unprocessed film and new film. The film is also controlled accurately from the Intermittent Sprocket to a point far above the Aperture, insuring a far steadier projected image. I\ew Type Film Trap construe* tion. To further insure the utmost steadiness of the projected picture, the Film Trap design includes, in addition \o the regular Guide Rollers heretofore used to control side sway, replaceable guides spaced with absolute atcuracy. These guides art in conjunction with the guide rollers aforementioned and prevent side sway of the film such as was possible on all earlier models.
