Claim 3
Dependent Claim
45 words
Apparatus for selectively processing sheets as set forth in claim 1 in which, said pair of eccentric shafts are arranged to rotate in the same direction and provide a non-circular motion for the upper surface of the lower platen with both horizontal and vertical components.
Claim 4
Dependent Claim
76 words
Apparatus for selectively processing sheets as set forth in claim 1 which includes, gear means on both of said eccentric shafts, a drive shaft extending longitudinally beneath said lower platen, gear means on said drive shaft meshing with gears on said eccentric shafts so that rotation of said drive shaft rotates said eccentric shafts in the same direction and in timed relation to each other to provide a non-circular motion to said lower platen upper surface.
Claim 5
Dependent Claim
53 words
Apparatus for selectively processing sheets as set forth in claim 1 which includes, conveyor means to convey sheets between said upper and lower platens, conveyor drive means to maintain said sheets in motion while said lower platen moves vertically toward said upper platen and said upper platen moves horizontally with said lower platen.
Claim 6
Dependent Claim
59 words
Apparatus for selectively processing sheets as set forth in claim 4 which includes, pairs of sprockets positioned on opposite ends of said platens, endless chains reeved about said sprockets, transverse gripper bars connected to said endless chains, and gripper means on said gripper bars to engage the front edge of said sheet and convey said sheets between said platens.
Claim 7
Dependent Claim
44 words
Apparatus for selectively processing sheets as set forth in claim 4 which includes, means connecting said conveyor drive means and one of said first named eccentric shafts so that said conveyor drive means is driven in timed relation to the movement of said platens.
Claim 8
Dependent Claim
35 words
Apparatus for selectively processing sheets as set forth in claim 1 in which, said platens include means to cut and crease said sheet therebetween while said platens are moving and said sheet is moving therewith.
Claim 9
Dependent Claim
38 words
Apparatus for selectively processing sheets as set forth in claim 7 which includes, a stripper mechanism positioned adjacent to said platens, said stripper mechanism arranged to remove the cutout portions of said sheet while said sheet is moving.
Claim 10
Dependent Claim
126 words
Apparatus for selectively processing sheets as set forth in claim 8 in which, said stripper mechanism includes, an upper platen movably supported in said side frame members for horizontal reciprocatory motion relative to said frame members, a pair of eccentric shafts journaled in said frame members, a lower platen positioned below said upper platen and having depending shaft receiving portions, said eccentric shafts journaled in said lower platen shaft receiving portions, drive means to rotate said eccentric shafts and move said lower platen both horizontally and vertically toward and away from said upper platen, means connecting said upper platen to said lower platen so that said lower platen moves said upper platen horizontally therewith while said lower platen moves toward and away from said upper platen.
Claim 11
Dependent Claim
51 words
Apparatus for selectively processing sheets as set forth in claim 9 in which, said drive means to rotate said eccentric shafts includes connecting means connecting said drive means to one of said first named eccentric shafts so that said stripper mechanism platens move in timed relation to said first named platens.
Claim 12
Dependent Claim
44 words
Apparatus for selectively proCessing sheets as set forth in claim 4 which includes, a sheet transfer mechanism operable to engage the front edge of said sheet, accelerate said sheet to the speed of said conveyor means and transfer said sheet to said conveyor means.
Claim 13
Dependent Claim
66 words
Apparatus for selectively processing sheets as set forth in claim 11 in which said sheet transfer mechanism includes, a drive shaft, a gripper device operable to move reciprocally, lever means connected to said gripper device and operable upon rotation of said drive shaft to open and close said gripper device, reciprocate said gripper device to accelerate the sheet and transfer said sheet to said conveyor means.
Claim 14
Dependent Claim
45 words
Apparatus for selectively processing sheets as set forth in claim 12 which includes, means connecting said transfer mechanism drive shaft to one of said first named eccentric shafts so that said transfer mechanism reciprocates in timed relation to the movement of said first named platens.
Claim 15
Dependent Claim
76 words
Apparatus for selectively processing sheets as set forth in claim 1 in which, said means connecting said upper and lower platens includes, a bracket member connected to the side of one of said platens and extending vertically toward the other of said platens, a channel-shaped receiver on the other of said platens, said bracket member positioned in said channel-shaped receiver and operable to move vertically therein and transmit horizontal motion from one platen to the other.
