Motography (Apr-Dec 1911)

118 MOTOGRAPHY Vol. VI, No. 3. through the rear open end of the casing, coiled springs attached at one end of the projecting ends of the shaft of the friction roll and at their opposite ends to the shaft of the inking roll, said springs operating to hold both rolls in yielding contact with the printing roll when the inking roll is in normal position and to hold the inking roll with its shaft in engagement with said notches when the same is moved into engagement therewith, and simultaneously force the friction roll toward the printing roll to grip a strip of paper between them and feed it out through the discharge slot in the front of the casing when said rolls are turned. No. 992,098. Film Handling Devices for Moving Picture Machines. Edwin R. Yanch, Galveston, Tex. In this improved "automatic rewinding" machine, which is "automatic" in rewinding because rewinding is not required, the film is reeled up upon the inside, the completed reel thus having the head end of the film, or the "leader," upon the outside. In the illustrations, the larger figure shows both feed and take-up reels, with the film passing down 992,098. ward from the one to the other. The smaller figure at the left shows the manner of handling the film at the take-up reel, the film strip B being brought down beside an open drum or winding barrel, I, and being carried into it in diagonal direction. By revolving the barrel the film is wound upon the inside, being pressed upon the inner surface of the barrel by the rollers 24. carried by spring arms. The claim is : In film winding mechanisms, a revoluble reel composed of separate sections, and a barrel adapted for receiving the film from the reel and adapted to wind the same within the barrel so that the front end of the film will be disposed outwardly of the innermost wound portion, and interchangeable film laying means carried by the barrel and reel respectively. No. 993,337. Film Rewinder. Percy L. Blasser, York, Pa. Next in value to a projecting machine which does not require rewinding at all, is a rewinding machine which will rewind the film with the least attention from the operator and with the least danger of injuring the film itself. In the invention for which this patent has been issued, Mr. Blasser accomplishes the results of automatic rewinding with safety for the film. The inventor's preliminary description, the description of operation, and one of the six claims are quoted from the patent : This invention relates to machines for rewinding motion picture films, and one of the principal objects of the invention is to provide a machine of simple construction for rewinding films on the primary reel for another exhibition of the pictures. Owing to the fragile character of these films a machine which will properly rewind said film must be delicately adjusted as to the amount of friction required to prevent the breaking of the films and to, at the same time, prevent the too free running of the film from the secondary to the primary reel. Too great friction would break or separate the film, while too little friction would let the film run off too rapidly to properly rewind it upon the primary reel. One of the principal objects of my invention is to provide a machine in which the friction shall be automatically regulated to properly rewind the films without danger of breaking and without feeding the film too rapidly to the primary reel.
