Abstract
Abstract In an electrographic copier, a buffer station for storing discrete sheets, adapted to have transferable images formed respectively thereon, and for distribution of such sheets into a track assembly where such sheets are transported into operative relation with electrographic process stations of such copier. The buffer station safely stores a plurality of sheets in spaced relation to prevent contact between adjacent sheets. The buffer station is indexable relative to the track assembly for alignment with such track assembly so as to receive a sheet from or distribute a sheet to the track assembly. The stored sheets are selectively released from the buffer station when respectively aligned with the track assembly.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
In an electrographic copier employing a plurality of discrete sheets adapted to have transferable images formed respectively thereon, said copier including a track assembly associated with electrographic process stations and having first and second remote portions where such discrete sheets respectively egress from and enter said track assembly, such sheets being transported about said track assembly into operative relation with such stations, a discrete sheet buffer station associated with said track assembly, said buffer station comprising: means for safely storing such discrete sheets, in spaced relation, and so as to substantially prevent contact of the respective surfaces of such sheets; means for indexing said storing means relative to said track assembly to align said storing means with said track assembly at a location adapted to selectively receive a sheet egressing from said first portion of said track assembly, and distribute a sheet to enter said second portion of said track assembly; and means operatively associated with said storing means for selectively releasing a stored sheet for distribution into said second portion of said track assembly.
Claim 2
Dependent Claim
175 words
In an electrographic copier employing a plurality of discrete sheets adapted to have transferable images formed respectively thereon, said copier including a track assembly associated with electrographic process stations and having first and second remote portions where such discrete sheets respectively egress from and enter said track assembly, such sheets being transported about said track assembly into operative relation with such stations, a discrete sheet buffer station associated with said track assembly, said buffer station comprising: means for safely storing such discrete sheets, in spaced relation, and so as to substantially prevent contact of the respective surfaces of such sheets; means for indexing said storing means relative to said track assembly to align said storing means with said track assembly at a location adapted to selectively receive a sheet egressing from said first portion of said track assembly, and distribute a sheet to enter said second portion of said track assembly; and means operatively associated with said storing means for selectively releasing a stored sheet for distribution into said second portion of said track assembly.
Claim 3
Dependent Claim
53 words
The invention of claim 1 wherein said storing means includes a housing having first and second spaced side walls adapted to respectively contact only opposed marginal edges of said sheets, a plurality of ribs connected to and extending perpendicularly from said side walls respectively to define a plurality of discrete sheet storing chambers.
Claim 4
Dependent Claim
42 words
The invention of claim 2 wherein said ribs extend from said respective side members a distance so as to engage only a minor portion of the surfaces of discrete sheets, received in said storing chambers, adjacent to such opposed marginal edges thereof.
Claim 5
Dependent Claim
92 words
The invention of claim 2 wherein said indexing means includes a reversible motor, means for coupling said motor to said housing so that when said motor is actuated said housing moves relative to said track assembly, and means for actuating and deactuating said motor to selectively align a storing chamber of said housing with said track assembly whereby a discrete sheet stored in such chamber is releasable into said second portion of said track assembly, and a discrete sheet from said first portion of said track assembly is receivable in such chamber.
Claim 6
Dependent Claim
58 words
The invention of claim 4 wherein said actuating/deactuating means includes a switch located relative to said track assembly for sensing the presence or absence of a sheet in a chamber aligned with said track assembly and producing signals respectively indicative thereof, and wherein said motor indexes said housing relative to said track assembly in response to such signals.
Claim 7
Dependent Claim
83 words
The invention of claim 1 further comprising means for supporting said storing means, said support means including means for enabling said storing means to move relative to said support means when indexed by said indexing means, and a member underlying said storing means to retain sheets therein, said member defining an opening aligned with said second portion of said track assembly and of a dimension to enable a sheet, upon release for distribution by said releasing means, to pass therethrough into said portion.
Claim 8
Dependent Claim
36 words
The invention of claim 6 where said releasing means includes a movable gate, and means for selectively moving said gate between a position for blocking said opening and a position remote from such opening blocking position.
