Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
169 words
In an apparatus for supplying documents to a reproduction machine, the machine including transport means for feeding documents to and returning documents from said reproduction machine, the combination of: means for supporting documents for use by said reproduction machine, said document supporting means including a tray for holding both documents to be fed to said machine and documents returned from said machine; said transport means including a primary transport adjacent the mouth of said tray adapted to feed documents forward singly from said tray to said machine; means interposable between documents returned to said tray and said primary transport to prevent unintended refeeding of returned documents by said primary transport, said interposing means being removable to permit refeeding of returned documents in said tray; and cover means adapted to overlay said tray, said cover means cooperating with said tray to reposition returning documents in said tray so that on removing of said document interposing means, said returned documents may be fed forward to said machine by said primary transport.

In an apparatus for supplying documents to a reproduction machine, the machine including transport means for feeding documents to and returning documents from said reproduction machine, the combination of: means for supporting documents for use by said reproduction machine, said document supporting means including a tray for holding both documents to be fed to said machine and documents returned from said machine; said transport means including a primary transport adjacent the mouth of said tray adapted to feed documents forward singly from said tray to said machine; means interposable between documents returned to said tray and said primary transport to prevent unintended refeeding of returned documents by said primary transport, said interposing means being removable to permit refeeding of returned documents in said tray; and cover means adapted to overlay said tray, said cover means cooperating with said tray to reposition returning documents in said tray so that on removing of said document interposing means, said returned documents may be fed forward to said machine by said primary transport.
Claim 3
Dependent Claim
69 words
The apparatus according to claim 1 in which said document supporting means includes an inclined base; means for supporting said cover means for swinging movement about the lower side of said base to enable said cover means to be swung outwardly and permit loading or unloading of documents in said tray; and means to limit opening movement of said cover means to a predetermined document loading and unloading position.
Claim 4
Dependent Claim
48 words
The apparatus according to claim 2 including means supporting said tray for swinging movement about an axis substantially coaxial with that of said cover means whereby said tray may be swung outwardly on opening of said cover means to facilitate loading or unloading of documents in said tray.
Claim 5
Dependent Claim
56 words
The apparatus according to claim 3 including lost motion drive means interconnecting said cover means with said tray operable following partial opening of said cover means to drivingly connect said tray with said cover means so that continued opening of said cover means to said pRedetermined document loading and unloading position swings said tray outwardly therewith.
Claim 6
Dependent Claim
46 words
The apparatus according to claim 4 including means biasing said tray in an inward closing direction whereby on closing of said cover means, said biasing means swings said cover inwardly toward said base to bring documents in said tray into operative relationship with said primary transport.
Claim 7
Dependent Claim
31 words
The apparatus according to claim 1 including means adapted on opening of said cover means to remove said document interposing means to facilitate loading or unloading of documents in said tray.
Claim 8
Dependent Claim
84 words
The apparatus according to claim 1 in which said tray is comprised of a pair of substantially identical shelflike members arranged in facing relationship to one another, the sides of said members adjacent the mouth of said tray being beveled outwardly to facilitate return of documents into said tray, said members being arranged for lateral movement toward and away from one another to enable the size of said tray to be adjusted; and detent means to releasably maintain said tray members in adjusted position.
Claim 9
Dependent Claim
27 words
The apparatus according to claim 1 including means to direct low pressure air against documents returning to said tray whereby to guide returning documents into said tray.
Claim 10
Dependent Claim
42 words
The apparatus according to claim 8 in which said cover means includes a plenum chamber forming a roof over documents returning to said tray when said cover means is closed; said pressure air directing means comprising openings in said plenum chamber roof.
Claim 11
Dependent Claim
19 words
The apparatus according to claim 1 including means adapted to electrically neutralize static electric charges on said returning documents.
