Claim 1
Independent Claim
191 words
In a document transport system having means for holding a stack of documents to be transported, processed and returned, and means for separating returned documents from those in the stack yet to be processed; the improvement of a drive linkage for said separating means comprising a rotary drive crank, a link pivotally connected to said crank, said separating means being connected to said link at a point remote from said crank, a pivot arm having one end pivotally connected to a fixed point and its other end pivotally connected to said link at a point intermediate said crank connection and said separating means connection, said intermediate point being offset from a line between said pivotal connection of said link crank and said point remote from said crank pivotal means connecting said separating means to said link at said point remote from said crank, and means biasing the last-mentioned pivotal means in one pivotal direction whereby rotation of said drive crank one revolution causes said separating means to traverse a circumambient path out from under a stack of documents in said holding means and then over said stack to the top thereof.
Claim 2
Dependent Claim

In a document transport system having means for holding a stack of documents to be transported, processed and returned, and means for separating returned documents from those in the stack yet to be processed; the improvement of a drive linkage for said separating means comprising a rotary drive crank, a link pivotally connected to said crank, said separating means being connected to said link at a point remote from said crank, a pivot arm having one end pivotally connected to a fixed point and its other end pivotally connected to said link at a point intermediate said crank connection and said separating means connection, said intermediate point being offset from a line between said pivotal connection of said link crank and said point remote from said crank pivotal means connecting said separating means to said link at said point remote from said crank, and means biasing the last-mentioned pivotal means in one pivotal direction whereby rotation of said drive crank one revolution causes said separating means to traverse a circumambient path out from under a stack of documents in said holding means and then over said stack to the top thereof.
Claim 3
Dependent Claim
168 words
In a document transport system having means for holding a stack of documents to be tranported, processed and returned, and means for separating returned documents from those in the stack yet to be processed; the improvement of a drive linkage for said separating means, comprising a rotary drive crank, a link pivotally connected to said crank, said separating means being connected to said link at a point remote from said crank, a pivot arm having one end pivotally connected to a fixed point and its other end pivotally connected to said link at a point intermediate said crank connection and said separating means connection, pivotal means connecting said separating means to said link at said point remote from said crank, and means biasing the last-mentioned pivotal means in one pivotal direction whereby rotation of said drive crank one revolution causes said separating means to traverse a circumambient path out from under a stack of documents in said holding means and then over said stack to the top thereof.
Claim 4
Dependent Claim
