Abstract
Abstract A conveyor system, particularly for riveting binders, having an endless conveyor comprised of rigid link members pivotably connected together and caused to intermittently move by fluid motor means having reciprocal members. Two such motor means are operated sequentially in a predetermined manner so that one motor means reciprocates to a position so that it no longer supports a link member. This permits the link member to rotate through an arc of approximately 90* . Then the other motor means moves the conveyor through a distance corresponding generally to the length of a link member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
81 words
A conveyor system comprising a frame supporting an endless conveyor having rigid link members pivotably connected thereto, intermittently operated fluid motor means having a reciprocal member for contacting a bottom run link member and moving the same, and intermittently operated motor means for supporting the terminal horizontally disposed top run link member and selectively permitting the same to pivot downwardly to provide slack in the conveyor to be taken up by movement of a link member by said fluid motor means.
Claim 2
Dependent Claim
81 words
A conveyor system comprising a frame supporting an endless conveyor having rigid link members pivotably connected thereto, intermittently operated fluid motor means having a reciprocal member for contacting a bottom run link member and moving the same, and intermittently operated motor means for supporting the terminal horizontally disposed top run link member and selectively permitting the same to pivot downwardly to provide slack in the conveyor to be taken up by movement of a link member by said fluid motor means.
Claim 3
Dependent Claim
51 words
A conveyor system in accordance with claim 1 wherein said fluid motor means includes a cylinder having a reciprocal piston rod, a pusher on one end of the piston rod, said pusher being adjacent the gap between adjacent link members when the piston rod is at one end of its stroke.
Claim 4
Dependent Claim
20 words
A conveyor system in accordance with claim 1 wherein said fluid motor means is pivotably supported adjacent one end thereof.
Claim 5
Dependent Claim
44 words
A conveyor system in accordance with claim 1 wherein said motor means for supporting the terminal link member includes a fluid motor having a reciprocal piston rod, and a supporting member connected to said piston rod for supporting the terminal link member from below.
Claim 6
Dependent Claim
35 words
A conveyor system in accordance with claim 1 including horizontally disposed tracks, wheels connected to said link members at the pivotable joint between adjacent link members, said wheels being adapted to ride on said tracks.
Claim 7
Dependent Claim
124 words
A conveyor system in accordance with claim 1 wherein said fluid motor means includes a piston rod having retracted and extended positions, said motor means for supporting the terminal link member including a piston rod having extended and retracted positions, a link member support on said last mentioned piston rod, and means for moving said link member support through a distance approximately equal to the length of the link members so as to permit the terminal link member to pivot downwardly and then cause the first mentioned piston rod to move from a retracted to an extended position so that it may push a link member on the lower run of the conveyor to a distance corresponding to the length of a link member.
Claim 8
Dependent Claim
46 words
A conveyor system in accordance with claim 1 wherein said fluid motor means is pivotably supported at one end and resiliently supported at its other end so as to be generally horizontally disposed and substantially parallel to and adjacent to the lower run of the conveyor.
Claim 9
Dependent Claim
45 words
A conveyor system in accordance with claim 1 including at least one rivet setting anvil on each link member, and a rivet setting machine above the upper run of the conveyor, the rivet setting machine including a drive assembly adapted to cooperate with the anvil.
