High speed duplicator with stapler and staple loading arrangement

Claim 2

In a stapling apparatus having a clamping/stapling position whereat a plurality of sheets to be stapled are clamped preparatory to the application of a staple thereat, a magazine for holding one or more sticks of staples, and a staple follower within the magazine for contacting the end of a stick, the improvement comprising: drive means engageable with the follower and adapted when in its release mode to provide a force thereon in a direction to force the staples toward the clamping/stapling position, means for retracting the follower out of the magazine for permitting loading thereof with sticks of staples, said means for retracting the follower being operatively connected to said drive means for conditioning the same to its release mode, and means for selectively controlling said drive means between its non-release mode and its release mode.

Claim 3

In a stapling apparatus having a clamping/stapling position whereat a plurality of sheets to be stapled are clamped preparatory to the application of a staple thereat, a magazine for holding one or more sticks of staples, and a staple follower within the magazine for contacting the end of a stack, the improvement comprising: spring means engageable with the follower and adapted when unwinding to provide a force thereon in a direction to force the staples toward the clamping/stapling position, means for retracting the follower out of the magazine for permitting loading thereof with sticks of staples, said means for retracting the follower being operatively connected to said spring means for winding the same during retracting of the follower, and means for selectively releasing said spring means to effect unwinding thereof and thereby provide a force on the sticks of staples toward the clamping/stapling position.

Claim 4

In a stapling apparatus having a clamping/stapling position whereat a plurality of sheets to be stapled are clamped preparatory to the application of a staple thereat, a magazine for holding one or more sticks of staples, and a staple follower within the magazine for contacting the end of a stack, the improvement comprising: spring means engageable with the follower and adapted when unwinding to provide a force thereon in a direction to force the staples toward the clamping/stapling position, means for retracting the follower out of the magazine for permitting loading thereof with sticks of staples, said means for retracting the follower being operatively connected to said spring means for winding the same during retracting of the follower, and means for selectively releasing said spring means to effect unwinding thereof and thereby provide a force on the sticks of staples toward the clamping/stapling position.

Claim 5

In a stapling apparatus having a clamping/stapling position whereat a plurality of sheets to be stapled are clamped preparatory to the application of a staple thereat, a magazine for holding one or more sticks of staples, and a staple follower within the magazine for contacting the end of a stick, the improvement comprising: means associated with the follower and adapted to provide a force thereon in a direction to force the staples toward the clamping/stapling position when in one condition of operation, means for retracting the follower out of the magazine for permitting loading thereof with sticks of staples, said means for retracting the staple follower being operatively connected to said force providing means for placing the same in said one condition of operation, and means for maintaining said force providing means inoperative relative to providing a force upon the staple follower, and for selectively releasing the force.

Claim 6

In a stapling apparatus having a clamping/stapling position whereat a plurality of sheets to be stapled are clamped preparatory to the application of a staple thereat, a magazine for holding one or more sticks of staples, and a staple follower within the magazine for contacting the end of a stick, the improvement comprising: means associated with the follower and adapted to provide a force thereon in a direction to force the staples toward the clamping/stapling position when in one condition of operation, means for retracting the follower out of the magazine for permitting loading thereof with sticks of staples, said means for retracting the staple follower being operatively connected to said force providing means for placing the same in said one condition of operation, and means for maintaining said force providing means inoperative relative to providing a force upon the staple follower, and for selectively releasing the force.

Claim 7

In a copier having a document handling apparatus adapted to circulate a set of document sheets, copy sheet processor and a collator arranged to receive processed copy sheets representative of the set of document sheets, the improvement comprising: stapling apparatus having a clamping/stapling position whereat a collated set of copy sheets indicative of the set of document sheets are clamped preparatory to the application of a staple thereat, a magazine for holding one or more sticks of staples, and a staple follower within the magazine for contacting the end of a stick, the improvement comprising: drive means engageable with the follower and adapted when in its release mode to provide a force thereon in a direction to force the staples toward the clamping/stapling position, means for retracting the follower out of the magazine for permitting loading thereof with sticks of staples, said means for retracting the follower being operatively connected to said drive means for conditioning the same to its release mode, and means for selectively controlling said drive means between its non-release mode and its release mode.

Claim 8

In a copier having a document handling apparatus adapted to circulate a set of document sheets, copy sheet processor and a collator arranged to receive processed copy sheets representative of the set of document sheets, the improvement comprising: stapling apparatus having a clamping/stapling position whereat a collated set of copy sheets indicative of the set of document sheets are clamped preparatory to the application of a staple thereat, a magazine for holding one or more sticks of staples, and a staple follower within the magazine for contacting the end of a stick, the improvement comprising: drive means engageable with the follower and adapted when in its release mode to provide a force thereon in a direction to force the staples toward the clamping/stapling position, means for retracting the follower out of the magazine for permitting loading thereof with sticks of staples, said means for retracting the follower being operatively connected to said drive means for conditioning the same to its release mode, and means for selectively controlling said drive means between its non-release mode and its release mode.
