Arthur J. Abrams, New York, N. Y. Application July 2, 1936, Serial No. 88,564 ‘_1 Claim. (CI. 88-17) Fig. 1 is a front edge view of a ?lm magazine This invention relates to improvements in ?lm magazines adapted for use in’ motion picture as at present contemplated. ,. Heretofore, magazines of this type were pro zine cover removed. for winding or unwinding the film within the be driven by the camera mechanism as the ?lm 1 _ - . ' ' Fig. 4 is a plan view of a ?lm reellernploy'ed I in saidmagazine. The film magazine comprises a casing 5 formed with a back wall 6, top and bottom walls ‘I, a front 10 wall 8_ and a rear wall 8. The cover it thereof is advanced past the exposure aperture of the magazine. In addition to the above means, a claw ‘or sprocket or the like is employed ifor also forms the front wall and is provided with‘ > - a peripheral ?ange II for tight engagement The above type of magazine is necessarily _ quite complicated and relatively expensive, and considerable skill is needed for introducing such with the front edges of the walls ‘I, 8 and '9. in the present instance. the front wall a is provided with an exposure aperture i2 and with an elongated opening l3 so ?lm advancing a magazine into a camera. The present invention therefore, seeks to pro vide an improved form‘of magazine, which is not only of simple and very inexpensive construc vrz'ieans, such as a claw or the like, may engage the sprocket hoies h of the ?lm F in the maga aine. If desired, another hole Ito may be pro 20 vided to be employed for setting a sprocket hole 72 in proper relation to the film advancing means and thus making certain that said means would 20 tion. but is also readily introduced into’ a cam era even by unskilled persons. 5 of magazine. magazine,'and these means were arranged to ' ' - ‘Fig. 3 is a similar view of a modi?ed form 5 vided with means in the form of reels or spools advancing the film. ~‘ Fig. 2 is a side view thereof with the maga cameras. Hence it is an object of the invention to providea ?lm maga zine in which all spools and reels are emitted and in which a roll of ?lm, provided with an N) CH initial "set" or curl, is placed in one ?lm com-l surely engage the sprocket holes exposed by the opening l8. . ‘ exposure aperture to a position in another film The mentioned curl oi the dim suitable material. ‘This insert shown at E4, is larger diameter and without the aid of any take~ somewhat larger similar opening It. This open ing forms film compartments, the compartment compartment. 25 The magazine is provided with an insert (Fig. 2i which may be of wood, Bakelite, or other partment' to be intermittently moved past the provided at its upper end with a substantially ~ causessaid ?lm to reform into a roli commen 30 surate with its initial 'torm, but of somewhat ' circular opening it and at its lower end with a up mechanism. v - A further object is the provision of a ?lm magazine adapted for the housing of a film roll without the aid or spools'or reels, and one which requires no take-up mechanism-one which re quires no coupling or connection of any kind with any moving part of the camera other than the association of the clawor equivalent ?lm advancing means, with the sprocket holes of the ?lm. - ~ ~ The invention also seeks to provide simple means for applying a drag to the ?lm as it is i5 serving to accommodate a ?lm roll R and the compartment I5 serving similarly for the ex 35 posed ?lm which forms the roll R1. ‘Between the two compartments, the insert it is provided with a central portion terminating in a wall El adjacent to the magazine wall 8 and spaced therefrom a distance somewhat greater than the ?lm thickness. The upper and 40 lower portions oi the insert are arranged with Walt portions l8 designed to abut the wall 8 and to therefore insure the mentioned spacing be being moved from one compartment to the other 7 tween. the walls 8 and II. . In. the above‘ manner,‘ the ?lm may freely pass 45 to obviate promiscous unwinding of the ?lm roll. Another contemplated feature of the invention resides in the novel gmanner of attaining the from the compartment ii to the compartment I6, yet being maintained in a flat ‘condition espe cially when passing by the exposure aperture l2. However, the speed at which the ?lm is ad With the above and other numerous features, vanced, although intermittent, ‘may cause pro objects and advantages in mind, the invention . miscous unwinding of the ?lm roll R. and thus resides in the embodiment thereof as‘ illustrated destroy the registration position of the sprocket in the accompanying drawing and as described holes h exposed by the opening M. It is, there in the following speci?cation. ' ' ~.tore, desired to retard the movement of the ?lm 'pre-set ?lm roll. 66 In the drawlnl: ‘ - > excqt when politivei'y moved by the film ad 2 2,137,601 vancing means to prevent overrunning of the film. A simple manner of accomplishing this is to apply a drag on the film as by forming a kink or bend’therein such as shown at I! as the film passes through the throat 20 of the com partment i5. Said throat is formed by an upper lip 2i set inwardly in relation to a lower lip 22 on the insert it. This form of throat also serves to wipe the ?lm clean of dust or other foreign 10 matter which may be on said film. The throat ‘23 of the compartment (6. is ar ranged so the film may freely pass into said compartu out after passing the opening i8. It will be noted that, as the ?lm enters the compartment til, it immediately starts to re curl and it is essential that it do otherwise the film may form divers serpel' re loops which would fill the compartment ant " 1.4' resistance to oncoming film therelnto. roll it is given an initial “e” tially the following ma The ?lm is ’“ son, the i enlist-am suhstantially as J. or the like is Wound condi tion. The roll is then subjected to a tempera~ ture in excess of any temperatiu'e it may en. counter in ordinary usage. This will cause the emulsion, which is on one surface of the ?lm, to soften and reset itself on, the ?lm so that said 39 ?lm is given an inherent tendency to curl under normal handling and storing temperatures. The roll is then rewound, with its outer couvolutions innermost so that the exaggerated curvature of the innermost convolutions (now outermost) seek to maintain the roll in a close wound condi~ tion at all times thereafter. Now, when a roll is placed in th, compartment it of a magazine and its outer convolutions are strung past the magazine apertures to pass into the compartment 68, this end of the ?lm will immediately seel: a, curled condition as shown. Another'forni film magazine is shown in Figure 3 wherein, instead of the ?xed insert it, a freely hung plate 2! is designed to lightly press against the film F. This plate is provided with an angulated portion 28 at each end which rides on an angled portion 21 formed on a bracket 28. It can be seen that the plate 25 is dragged down wardly by its light frictional engagement with the ?lm and because of the angular engagement at 28 and 2!, said plate is forced outwardly to wards the front wall 8 of the magazine. If desired, as shown, the plate 25 may be ‘ formed with reentrantly bent portions 29 to form compartments l5“ and I6“ commensurate re~ spectively to compartments l5 and I6 previously described. From the foregoing it can be seen that a film magazine, in its preferred forms, has been pro~ vided and that a film roll peculiarly adapted for use in such a magazine has also been provided. While this disclosure is at present preferred, it is obvious that skilled persons may employ the - principles here set forthin various ways. Hence interpretation oi’ the invention as claimed should rather be based on the prior art than on the instant disclosure. I claim: A ?lm magazine having in combination a cas— lag having an apertured wall, a bracket ?xed wit n the casing, said bracket having extending arms substantially parallel with the apertured wall of the casing, the end of one of said arms 30 being angled in a direction away from said aper tured wall, the end of the other of said arms be~ ing angled in a direction toward said apertured wall, a member freely hung over said bracket and arms, said member having angled portions corre 35 sponding to the angled portions of the arms, passage space for a film strip between the aper tureo. wall and said member, said member and said arm ends cooperating to urge the film strip into light frictional contact with the apertured well during movement of said film in one 40 direction.
