The mechanism comprises a hydraulic circuit having a power driven pump; a reservoir for hydraulic fluid, and a motor for each wheel or two or more coaxial wheels of the carriage. The motor has a movable driven member therein and ports for the infeed and outfeed of fluid therethrough. There are connecting means between the pump, the reservoir and the ports whereby the fluid can be circulated through the motor to drive the driven member thereof. There is also a connection between the driven member of the motor and the corresponding wheel or wheels whereby the motion of one is directly transmitted to the other and vice versa, depending on which is being driven at faster speed. In addition, there are means in the hydraulic circuit for varying the speed of the driven member, and means whereby the vehicle operator can control the speed varying means to adjust the rotational speed of the respective wheel or wheels of the carriage in relation to the speed of the vehicle.

Combined drive and brake mechanism for a wheeled vehicle carriage

A device for unloading exposed film from a cassette, discarding a backing strip which is wound with the film, discharging the cassette body and conveying the film to a light-free storage box. The cassette is initially loaded into the device through a shutter-closable aperture and received by a downwardly inclined cradle. Upon initiation of the loading cycle, the loading aperture shutter closes and a pneumatic ram lifts the cradle to place the cassette against the inlet of a film guide. A motor raises a violator probe after the cassette is in place to guide the backing paper between a pair of powered rollers which draw the backing strip from the cartridge thereby carrying the film into the film guide. The backing strip is discharged through a series of ducts to be discharged outside the machine. Film entering the guide is directed past the storage box by a pair of pivotally mounted guide doors which open when the leading edge of the film reaches a downstream optical sensor to allow film to enter the storage box. After all of the film has been removed from the cassette and processed by downstream splicer mechanisms, the cassette cradle is lowered and the cassette is discharged through a series of ducts outside the machine. The loading aperture shutter then opens to receive a new cassette. If the backing strip fails to draw the film from the cassette, the film is automatically rewound into the cassette, the cradle is lowered and the cartridge is routed into a light-free bag instead of the discharge receptacle.
