Abstract: An automatic document handler for supplying documents singly to the platen of a processing apparatus such as a copying machine. Following copying, each document is returned to the document supply where the used documents are kept separated from documents awaiting copying by means of a resettable bail bar. To position the documents properly for copying, the document handler includes a register against which the document trailing edge is abutted through reversal of the platen transport belt. To allow the document to be removed and the platen cleared for the next document, means are provided to remove the register and lower a document deflector into an intercept position, the deflector then serving to guide the document into a predetermined return path back to the document supply without interfering with movement of the next document forward.

Extending along the sheet path adjacent to the inlets of the bins are a pair of helical screw members which rotatably support and advance a carriage carrying deflector members which direct the copy sheets into the bins. The drive for rotating the helical screw members include a motor spring which drive a single revolution latching device to provide intermittent movement of the carriage past the inlets of each of the bins. A clutch which is connected to the drive of the sheet transport rewinds the motor spring after untensioning thereof after a sorting run.

Abstract: A sheet feeding device adapted to separate a single sheet from a stack of sheets and forward the separated sheet away from the stack for subsequent processing. The apparatus includes a feed belt disposed adjacent one edge of the stack for contact with the lead edge of the top sheet in the stack to separate the sheet therefrom. Gate means biased into engagement with the feed belt provide a forward stop for the sheet stack, actuation of the feed belt causing the top sheet in the stack to be forced between the low friction upper surface of the gate means and the feed belt to move the top sheet off from the stack, the biased gate means preventing passage of multiple sheets by the feed means.

Abstract: A plurality of transfer conveyors are arranged at right angles to and spaced along a main conveyor for transferring selected sheets from said main conveyor and either dropping them in a reject bin or stacking them in separate piles depending upon the size of the sheets. The transfer conveyors overlie the main conveyor and operate to pick up sheets from the main conveyor by Bernoulli's principle and permit them to slide by gravity to the reject bin while supported in non-contacting relation by the nozzles. The nozzles are selectively actuated in groups to achieve the pickup and reject functions. Sheets not rejected leave the lower end of the transfer conveyor and fly free to the stack receiver which is positioned in line with the conveyor and spaced outwardly therefrom.

Abstract: An arrangement for the stackwise depositing of individual sheets of equal lengths in a repository or file by means of a conveying arrangement which includes one or more vacuum conveyor rolls or webs, adapted to transport successive sheets which are introduced in a time sequence from an input to the repository at a definite conveying speed, and including a braking installation located preceding or ahead of the repository, which deflects the end of each sheet downwardly out of the plane of conveyance and reduces the conveying speed to a speed which provides for an undisturbed deposition, and wherein the aspirating effect of a vacuum conveying roll which is located in proximity to the braking installation is interrupted during actuation of the braking installation.

Abstract: A transport mechanism for sheets of X-ray film includes a pair of cooperating rollers, at least one of which is hollow, between which the top sheet of a stack of sheets in a loading cartridge is transported to a location within the associated X-ray machine, where it is exposed. The attachment of the sheet of film to the hollow roller is aided by reducing the air pressure therein, providing suction to the film through a slot or slots in the periphery of the hollow cylinder. The drive assembly for the rollers includes various switches and relays, actuated automatically by cams or manually, for controlling the transport of the film into the X-ray machine and for delivering the exposed film to a developing machine.
