Abstract: A threading device is provided for use with a motion picture projector of the type adapted to receive a roll of film upon a rotatable spindle which may be inside a cartridge. The threading device includes a support member that is adapted to be moved into contact with a received cartridge to align and firmly hold the cartridge in position. The threading device further includes a member having a hook portion that is adapted to be moved through an opening in the wall of the cartridge and into close proximity with the roll where it engages an opening in the leading end portion of the rotating roll of film. After the film is engaged by the hook member, the hook extracts the leading end of the film from the cartridge and delivers it to transport means of the projector. The hook is then disengaged from the film and moved to a retracted position to avoid interfering with the normal operation of the projector.

Abstract: There is disclosed herein a capstan and pinch roller assembly for use in moving material in strip form, such as for moving motion picture film in a cartridge-loaded motion picture projector. The pinch roller is pivotally mounted and normally remains in a rest position for allowing entry of a film cartridge or the like into the machine. Insertion of the cartridge into the machine engages a member of the pinch roller assembly to move the roller into a second position, from which it is then moved to a final, capstan-engaging, position by means of an electromagnet. The electromagnet thus serves to finally position the roller, and to properly bias the pinch roller against the capstan. A suitable sound pick-up, such as an optical or magnetic pick-up, also may be positioned by movement of the pinch roller assembly. This invention relates to apparatus for moving webs of strips of material and more particularly to an improved pivotally mounted pinch roller assembly for use with cartridge loaded motion picture projectors and the like.

Abstract: A motion picture projector wherein the top wall of the housing supports a detachable upright duct for a stack of horizontal film-containing cassettes. The lowermost cassette of the stack dwells in a projection position in which the film can be automatically withdrawn from such cassette to be threaded through the projector and attached to the core of the takeup reel. An automatic rewinding unit rewinds the film onto the supply reel in the cassette occupying the projection position, and such cassette is thereupon expelled from projection position by a pusher to enter a detachable collecting receptacle. The lowermost cassette of the stack in the duct descends by gravity and occupies the projection position when the pusher returns to its retracted position. The guide means wherein the film passes from the supply reel in the cassette occupying the projection position to the takeup reel in the housing of the projector has a channel which twists the film through 90*.

Abstract: A cassette for use in cassette-loaded motion picture projectors has a pair of sections one of which carries a separable retaining member which can be used to secure the inner end of convoluted motion picture film to the hub of a supply reel. The retaining member is glued to or integral with the respective section and can be broken off by the user to be inserted into a socket of the supply reel in order to clamp the inner end of the film against the inner side of the hub. The position of the retaining member on the one section can be such that a supply reel can be inserted into the housing only when the retaining member is detached. The retaining member does not interfere with insertion of an empty supply reel.

Abstract: THE HOUSING OF A MOTION PICTURE PROJECTOR IS FORMED WITH A CHANNEL FOR A SET OF CLOSELY ADJACENT CASSETTES EACH OF WHICH CONTAINS A SUPPLY REEL FOR CONVOLUTED MOTION PICTURE FILM. THE CASSETTES ARE MOVABLE STEPWISE BY AN ADVANCING MECHANISM SERVING TO PLACE SUCCESSIVE CASSETTES INTO A PROJECTION POSITION IN WHICH THE FILM IS AUTOMATICALLY DRAWN FROM THE RESPECTIVE SUPPLY REEL, THE IMAGES OF ITS FRAMES PROJECTED ONTO A SCREEN, AND THEREUPON RETURNED INTO THE CASSETTE, EITHER WHILE THE CASSETTE DWELLS IN THE PROJECTION POSITION OR WHILE THE CASSETTE DWELLS A REWINDING POSITION IMMEDIATELY DOWNSTREAM OF THE PROJECTION POSITION. THE MOTOR FOR THE ADVANCING MECHANISM IS STARTED IN RESPONSE TO TENSIONING OF FILM DURING THE LAST STAGE OF WITHDRAWAL FROM THE CASSETTE OCCUPYING THE PROJECTION POSITION, AND THE MOTOR IS ARRESTED BY A PORTION OF THE ADVANCING MECHANISM WHEN THE TRANSPORT OF CASSETTES BY A STEP IS COMPLETED.

Abstract: A reel-over-reel tape cartridge having a pair of axially aligned tape hubs and improved means for mounting the hubs for rotation independently of each other within a cartridge housing. One hub has a tubular extension permitting it to be rotatably mounted on one wall member of the housing and the other hub has an extension and a tubular body to permit it to be rotatably mounted on the one hub and on a second wall member of the cartridge housing. The hubs are formed to permit a rotatable drive member to be alternately coupled thereto to cause rotation thereof in the same direction to avoid the need for a reversible drive means for the hubs. The cartridge can be provided with a removable reel having a tape which mates with a tape leader attached to a rotatable hub in the cartridge for receiving the tape of the removable reel. The removable reel feature can also be used with a cartridge having the reels side by side with each other.

Abstract: A leader on a web coacts with a hook which projects into a reel chamber in a case to limit web recoil into, and interfere with initiation of web removal from, the case. The leader also coacts with a reel on which the web is wound to prevent web ravel. The leader has an aperture and is fashioned with a pair of sloping shoulders which are wider than the spacing of the reel flanges such that upon web recoil the shoulders engage the flanges causing the leader to bend and displace the aperture toward engagement with the hook and to tension the reel to cause its frictional retention.
