Abstract
Abstract A system for producing sets of copies from documents that are copied in repeated cycles. A transport delivers copies to an intermediate tray which collects them in a set and then separates each set from a previous set in offset fashion. A control logic provides for different modes of operation in which there is a book mode of operation and a normal copying operation and also provides appropriate signals for the offsetting of the sets as well as ejection of the sets into an output tray.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
159 words
In a copying machine in which documents are advanced from a supply source to a platen and then returned to the supply source in repeated cycles, apparatus for producing identifiable collated sets of copies comprising gate means including a displaceable member for receiving copy sheets advanced along a predetermined path and movable from a first position in the sheet path to a second position out of the sheet path in response to discrete electrical signals, set separation means disposed adjacent to said gate means operative to move laterally to the sheet path in response to discrete electrical signals, set eject means associated with said gate means operative to pinch a set of sheets and advance them to a receiving tray in synchronization with the movement of said gate means, and logic means to supply discrete signals to said gate means, set separation means, and set eject means at predetermined intervals to effect staggered sets of sheets in the tray.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
38 words
Apparatus according to claim 1 wherein said gate means, set separation means, and set eject means is drivingly connected with a common drive mechanism including at least one electrical clutch mechanism which remains energized for a predetermined interval.
Claim 4
Dependent Claim
35 words
Apparatus according to claim 2 wherein said drive mechanism is rotatable in a path to actuate signal means operative to deenergize said electrical clutch mechanism and means to reposition said drive mechanism for subsequent cycles.
Claim 5
Dependent Claim
37 words
Apparatus according to claim 3 wherein said set separation means and said set eject means each have an electrical clutch mechanism associated therewith and the former is energized every other time of which the latter is energized.
Claim 6
Dependent Claim
17 words
Apparatus according to claim 1 including jogging means positioned in the sheet path before said gate means.
Claim 7
Dependent Claim
35 words
Apparatus according to claim 5 wherein said jogging means comprises a plurality of paddle members mounted on a hub rotated on a shaft inclined at an acute angle to the plane of the sheet path.
Claim 8
Independent Claim
96 words
A method of producing collated sets of copy sheets printed in a copying machine from precollated documents copied in repeated cycles comprising the steps of feeding documents to an exposure station of a copying machine for copying thereof and then returning the documents to their original position in seriatim, collecting copies in a stack in an intermediate tray corresponding to the documents being copied, ejecting the stack to a final output tray, and separating each stack from a previous stack by imparting lateral movement to every other stack collected in the intermediate tray before ejection thereof.
