Abstract
Abstract A collator which utilizes sheet momentum to operate sheet diverting vanes includes over-center weight elements in the vanes. The vanes are rockably positioned to block and open a sheet conveyance path, and force exerted on the vane by the sheet and the over-center weight element as a sheet moves into a collection compartment tips the vane from a sheet diverting, path blocking position to a path freeing position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
359 words
A collator comprising: a housing adapted to be associated with a source of sheets to be collated, said housing having a plurality of compartments therein for receiving collated sheets, an access means for permitting access to said compartments, an entranceway defining means for diverting sheets from a source of sheets into said housing, and a sheet chute defining means positioned in said housing to receive sheets from said entranceway; a plurality of sheet diverter vanes each associated with one of said housing compartments and located to divert sheets from said chute into said associated compartment, each of said sheet diverter vanes having a base portion, a leading arm and a trailing arm each connected to said base portion, a rocker means on said base portion between said arms and rockably connecting each sheet diverter vane to said housing, a diverter vane rocking means movably mounted in said sheet diverter vane adjacent said rocking means, said diverter vane rocking means including a keeper chamber defined in said diverter vane and a weight located in said keeper chamber to be movable from a first position on the trailing arm side of said rocker means across a rocking axis defined by said rocker means to a second position located on the leading arm side of said rocker means, said diverter vanes being positioned adjacent said chute so that said vane leading arms block said sheet chute when said vane rocking means is in said second position and unblock said chute when said vane rocking means is in said first position, said vane rocking means of each diverter vane being moved from said second position to said first position by action of a sheet passing over said each vane from said chute into said associated compartment so that each vane is moved from a chute blocking sheet diverting orientation to a chute clearing orientation after diverting a sheet into an associated compartment so that a plurality of successive sheets are each successively diverted into successive compartments after bypassing the compartment into which a preceding sheet has been diverted; and a reset means for moving said diverter vanes into position to occlude said chute.

A collator comprising: a housing adapted to be associated with a source of sheets to be collated, said housing having a plurality of compartments therein for receiving collated sheets, an access means for permitting access to said compartments, an entranceway defining means for diverting sheets from a source of sheets into said housing, and a sheet chute defining means positioned in said housing to receive sheets from said entranceway; a plurality of sheet diverter vanes each associated with one of said housing compartments and located to divert sheets from said chute into said associated compartment, each of said sheet diverter vanes having a base portion, a leading arm and a trailing arm each connected to said base portion, a rocker means on said base portion between said arms and rockably connecting each sheet diverter vane to said housing, a diverter vane rocking means movably mounted in said sheet diverter vane adjacent said rocking means, said diverter vane rocking means including a keeper chamber defined in said diverter vane and a weight located in said keeper chamber to be movable from a first position on the trailing arm side of said rocker means across a rocking axis defined by said rocker means to a second position located on the leading arm side of said rocker means, said diverter vanes being positioned adjacent said chute so that said vane leading arms block said sheet chute when said vane rocking means is in said second position and unblock said chute when said vane rocking means is in said first position, said vane rocking means of each diverter vane being moved from said second position to said first position by action of a sheet passing over said each vane from said chute into said associated compartment so that each vane is moved from a chute blocking sheet diverting orientation to a chute clearing orientation after diverting a sheet into an associated compartment so that a plurality of successive sheets are each successively diverted into successive compartments after bypassing the compartment into which a preceding sheet has been diverted; and a reset means for moving said diverter vanes into position to occlude said chute.
Claim 3
Dependent Claim
21 words
The collator defined in claim 1 wherein said sheet diverter vanes are V-shaped with an apex portion forming said base portion.
Claim 4
Dependent Claim
