To all whom it may concern: from time to time as the roller is revolved- Be it known that I, VALTER CHIPPER- The raised portion or portions D of the FIELD, engineer, a subject of the King of roller B, (that is those segments which Great Britain, residing at Kmkora, have a greater radius than the normal diam- Woodlands avenue, Great Nelmes, Horneter of the roller) extend only in the dichurch, Romford, Essex, England, have iurection of the axis of the roller, while the vented certain new and useful Improvepressure roller G which had a continuous ments in Kinematograph Cameras and Pro' surface both in the direction of its axis and 'jecting Apparatus, and of'which the followin the direction of its periphery was carried in is a specification. below the lower end of a gate, and with such his invention relates to kinematograph an arrangement it has been found that the cameras and projectin apparatus, in which film has been liable to curl either around a film passes over 'a wa l of a stationary ms the feed or pressure roller, instead of keep,- ing or frame of the operating mechanism mg to the desired ipath when the film i5 and between said wall and a yielding gate first inserted in the ceding mechanism.
