Abstract
Abstract A nonrotatable tumbler cam mechanism is positioned coaxially with the transfer cylinder on the operator''s side of the press and is movable axially thereto. A cam actuated device is provided on the transfer cylinder for tumbling the perfector and two color grippers inwardly to transfer the trailing edge of the sheet from the perfector grippers to the two color grippers. A cam follower on the cam actuated device is actuated by the tumbler cam mechanism. A pair of gripper actuating cams are coaxially and nonrotatably mounted relative to the transfer cylinder on the drive side of the press. One of the pair of cams, referred to as a two color cam, is arranged to open and close the two color grippers for two color printing and the other of the pair of cams is arranged to open and close the perfector grippers and the two color grippers for perfector printing. The pair of cams, i.e., the two color cam and perfector cam, are secured to each other and movable axially relative to the transfer cylinder. The perfector grippers and two color grippers have a cam follower associated therewith that is actuated by either the two color cam or the perfector cam. The two color and perfector cams are connected through a lever mechanism to an actuator device that is arranged to move the pair of cams axially relative to the transfer cylinder. The tumbler is also connected to the actuator device located on an exterior portion of the press so that the actuator device simultaneously moves the pair of gripper actuating cams and the tumbler cam to adjust the transfer cylinder for either the two color or perfector printing.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
289 words
A sheet fed rotary press comprising, a transfer cylinder having first sheet engaging means arranged to receive the leading edge of the sheet from an adjacent cylinder and a second sheet engaging means arranged to receive the trailing edge of the sheet from an adjacent cylinder, first operating means on said transfer cylinder to rotate said first and second sheet engaging means inwardly toward the axis of said transfer cylinder and outwardly away from the axis of said transfer cylinder, second operating means on said transfer cylinder to operate and first and second sheet engaging means, first actuating means mounted adjacent said transfer cylinder and arranged to periodically move said first operating means upon rotation of said transfer cylinder and rotate said first and second sheet engaging means, second actuating means mounted adjacent to said transfer cylinder and arranged to periodically move said second operating means upon rotation of said transfer cylinder and actuate said first sheet engaging means, third actuating means mounted adjacent to said transfer cylinder and arranged to periodically move said second operating means upon rotation of said transfer cylinder and actuate said first and second sheet engaging means, adjusting means connected to said first and third actuating means, said adjusting means arranged to move said first and third actuating means into and out of operative position with said first and second operating means to thereby control the operation of said first and second operating means during rotation of said transfer cylinder, and means connecting said second actuating means to said third actuating means in a manner that said second actuating means moves into operative position with said second operating means when said third actuating means moves out of operative position with said second operating means.
Claim 2
Dependent Claim
289 words
A sheet fed rotary press comprising, a transfer cylinder having first sheet engaging means arranged to receive the leading edge of the sheet from an adjacent cylinder and a second sheet engaging means arranged to receive the trailing edge of the sheet from an adjacent cylinder, first operating means on said transfer cylinder to rotate said first and second sheet engaging means inwardly toward the axis of said transfer cylinder and outwardly away from the axis of said transfer cylinder, second operating means on said transfer cylinder to operate and first and second sheet engaging means, first actuating means mounted adjacent said transfer cylinder and arranged to periodically move said first operating means upon rotation of said transfer cylinder and rotate said first and second sheet engaging means, second actuating means mounted adjacent to said transfer cylinder and arranged to periodically move said second operating means upon rotation of said transfer cylinder and actuate said first sheet engaging means, third actuating means mounted adjacent to said transfer cylinder and arranged to periodically move said second operating means upon rotation of said transfer cylinder and actuate said first and second sheet engaging means, adjusting means connected to said first and third actuating means, said adjusting means arranged to move said first and third actuating means into and out of operative position with said first and second operating means to thereby control the operation of said first and second operating means during rotation of said transfer cylinder, and means connecting said second actuating means to said third actuating means in a manner that said second actuating means moves into operative position with said second operating means when said third actuating means moves out of operative position with said second operating means.
Claim 3
Dependent Claim
60 words
A sheet fed rotary press as set forth in claim 1 which includes, a pair of spaced press frame members, said transfer cylinder rotatably journaled in said press frame members, said first actuating means mounted on one of said press frame members, said adjusting means including means to move said first actuating means toward and away from said transfer cylinder.
Claim 4
Dependent Claim
48 words
A sheet fed rotary press as set forth in claim 2 which includes, means mounting said second and third actuating means on the other of said press frames, said adjusting means including means to move said second and third actuating means toward and away from said transfer cylinder.
Claim 5
Dependent Claim
81 words
A sheet fed rotary press as set forth in claim 1 in which, said first actuating means includes a cam disc having a cam surface thereon, said cam disc positioned coaxially relative to said transfer cylinder, said first operating means including a cam roller arranged to abut said cam surface, said adjusting means including means to move said cam disc axially relative to said transfer cylinder to move said cam surface into and out of operative position with said cam roller.
Claim 6
Dependent Claim
126 words
A sheet fed rotary press as set forth in claim 1 in which said second actuating means includes, a cam disc having a cam surface thereon, said third actuating means includes a cam disc having a cam surface thereon, both of said cam discs positioned coaxially relative to said transfer cylinder, said second operating means including a cam roller arranged to abut said cam surface on said second actuating means cam disc or said cam surface on said third actuating means cam disc, said adjusting means including means to move said second actuating means cam disc and said third actuating means cam disc axially relative to said transfer cylinder to alternatively move said cam disc surfaces into and out of operative position with said cam roller.
Claim 7
Dependent Claim
69 words
A sheet fed rotary press as set forth in claim 2 in which said adjusting means includes, a shaft member extending through said press fraMe member in parallel spaced relation to said transfer cylinder, means connecting said shaft member to said first actuating means and said third actuating means so that axial movement of said shaft is transmitted to both said first actuating means and said third actuating means.
Claim 8
Dependent Claim
42 words
A sheet fed rotary press as set forth in claim 6 in which said means connecting said shaft member includes, means to move said first actuating means and said third actuating means in opposite directions upon axial movement of said shaft member.
Claim 9
Dependent Claim
