Abstract: Automatic film threading mechanism for use in motion picture projectors, comprising a driven endless elastic belt a portion of which is pivotable into engagement with the outermost convolution of film on the core of the supply reel to thereby rotate the reel in a direction to pay out the film. The belt is trained over a roller which rotates about a fixed axis, and such roller is surrounded by a stationary guide member or flanked by two guide rolls which prevent the film from engaging the belt in the region of the roller so that the belt can engage the film only when its aforementioned portion is pivoted into engagement with the outermost convolution.
Abstract translation: 用于电影放映机的自动胶片穿线机构，包括从动的无端弹性带，其一部分可枢转地与供应卷轴芯部上的最外面的卷卷接合，从而沿着方向转动卷轴以支付 电影。 皮带被训练在围绕固定轴线旋转的滚筒上，并且这样的滚筒被固定的引导构件包围，或者由两个引导辊包围，这两个引导辊防止胶片与滚筒的区域中的皮带接合，使得皮带能够接合 只有当其上述部分枢转成与最外圈卷合时，该胶片才可以。

Abstract: THE TOP WALL OF THE HOUSING IN THE MOTION PICTURE PROJECTOR IS FORMED WITH AN INWARDLY EXTENDING CHAMBER FOR RECEPTION OF SMALL, MEDIUM-SIZED OR LARGE CASSETTES FOR CONVOLUTED MOTION PICTURE FILM. THE CASSETTES ARE PROVIDED WITH EXTERNAL LOCATING MEANS WHICH FACILITATE STACKING OF CASSETTES DURING STORAGE OR IN TRANSPORT. A PLATELIKE DETENT MEMBER IS MOUNTED IN THE HOUSING ADJACENT TO ONE SIDE OF THE CHAMBER AND IS BIASED AGAINST A CASSETTE IN THE CHAMBER. THE DETENT MEMBER HAS RETAINING MEANS WHICH CAN ENGAGE WITH THE LOCATING MEANS OF THE INSERTED CASSETTE.

Abstract: A supply real for motion picture film has a socket which can receive the free end of the innermost convolution of film, and an integral retaining device which can be readily broken off and has a clamping portion insertable into the socket to clamp the free end of the innermost convolution against the reel. The retaining device is further provided with an additional portion which extends beyond the socket when the latter received the clamping portion to serve as a means for preventing improper insertion of the reel into certain types of cassettes. The additional portion can be broken away from the clamping portion so that the reel, with the clamping portion inserted into the socket and with the additional portion broken away, can be inserted into cassettes of another type which do not permit insertion of reels with the additional portions of retaining devices extending beyond the sockets.
Abstract translation: 用于电影胶卷的电源具有能够接收胶片最内圈的自由端的插座，以及能够容易地分离并具有可插入插座中的夹持部分的一体式保持装置，以夹紧胶片的自由端 内卷卷对卷。 保持装置还设置有附加部分，当附加部分接收到夹持部分时，该附加部分延伸超过插座，以用作防止卷轴错误地插入到某些类型的盒中的装置。 附加部分可以从夹紧部分断开，使得具有插入插座中的夹持部分和附加部分被分离的卷轴可以插入到另一种类型的盒中，该盒不允许将卷轴插入附加 保持装置的部分延伸超过插座。

Abstract: A FILM TRANSPORTING MECHANISM FOR USE IN A MOTION PICTURE PROJECTOR COMPRISES A SHAFT WHICH ROTATES THE SHUTTER AND FIRST AND SECOND AXIALLY MOVABLE ADVANCING CAMS WHICH RESPECTIVELY IMPART TO THE PULL-DOWN MOVEMENTS NECESSARY TO EFFECT FORWARD AND REARWARD TRANSPORT OF MOTION PICTURE FILM. THE CAMS ARE MOVABLE AXIALLY OF THE SHAFT BY A SHIFTER DEVICE SO THAT ONE THERE OF IMPARTS TO THE PULL DOWN MOVEMENT BY THE WAY OF A SUITABLE FOLLOWER. THE FACE OF THE SECOND CAM DIFFERS FROM THE FACE OF THE FIRST CAM TO THE EXTENT NECESSARY TO COMPENSATE FOR THE CLEARANCE WITH WHICH THE CLAW OF THE PULL-DOWN EXTENDS INTO THE PERFORATION OF MOTION PICTURE FILM. THIS INSURES THAT THE FRAMES OF SUCH FILM REGISTER ACCURATELY WITH THE GATE AND WITH THE OPTICAL SYSTEM NOT ONLY DURING FORWARD BUT ALSO DURING REARWARD TRANSPORT OF THE FILM.
