Abstract
Abstract This disclosure relates to a can body transfer mechanism particularly adapted for use as part of an automatic coating and printing machine wherein can bodies and like tubular members are automatically positioned on mandrels and thereafter serially presented to coating and printing blankets. The transfer apparatus includes a vertically disposed feed screw which spaces can bodies and transfers them to a feed turret which, in turn, transfers the can bodies to a transfer turret. The transfer turret has generally horizontally disposed pockets axially aligned with mandrels carried by an endless chain and there is associated with the transfer turret a pusher turret having a plurality of pusher members thereon axially aligned with the turret pockets and the mandrels and automatically operable by a fixed cam in response to the rotation of the pusher turret to push can bodies from the transfer turret pockets onto the mandrels.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
55 words
An apparatus for placing can bodies on mandrels carried by a moving endless chain, said apparatus comprising a turret having pockets for receiving and supporting can bodies, said pockets moving in alignment with said mandrels for a portion of the mandrel travel, and pushers for pushing can bodies from said turret pockets onto said mandrels.
Claim 2
Independent Claim
55 words
An apparatus for placing can bodies on mandrels carried by a moving endless chain, said apparatus comprising a turret having pockets for receiving and supporting can bodies, said pockets moving in alignment with said mandrels for a portion of the mandrel travel, and pushers for pushing can bodies from said turret pockets onto said mandrels.
Claim 3
Dependent Claim
48 words
The apparatus of claim 1 together with an upright feed screw disposed adjacent to and at one side of said turret for positioning can bodies in vertically spaced relation for reception in said turret, and drive means for driving said feed screw and said turret in timed relation.
Claim 4
Dependent Claim
99 words
A transfer apparatus for can bodies comprising a transfer turret having generally horizontal extending and radially opening pockets for can bodies, a sprocket having an endless chain entrained thereon, mandrels carried by said endless chain at a spacing corresponding to the spacing of said endless chain at a spacing corresponding to the spacing of said turret pockets, means mounting said sprocket and said transfer turret for rotation in unison about a generally horizontal axis with said mandrels being in axial alignment with said turret pockets, and pusher means for pushing can bodies from said turret pockets onto said mandrels.
Claim 5
Dependent Claim
99 words
A transfer apparatus for can bodies comprising a transfer turret having generally horizontal extending and radially opening pockets for can bodies, a sprocket having an endless chain entrained thereon, mandrels carried by said endless chain at a spacing corresponding to the spacing of said endless chain at a spacing corresponding to the spacing of said turret pockets, means mounting said sprocket and said transfer turret for rotation in unison about a generally horizontal axis with said mandrels being in axial alignment with said turret pockets, and pusher means for pushing can bodies from said turret pockets onto said mandrels.
Claim 6
Dependent Claim
50 words
The transfer apparatus of claim 3 wherein said pusher means includes a pusher turret mounted for rotation about said axis in unison with said transfer turret and said mandrels, and a plurality of pusher members carried by said pusher turret in axial alignment with said turret pockets and said mandrels.
Claim 7
Dependent Claim
75 words
The transfer apparatus of claim 3 wherein said pusher means includes a pusher turret mounted for rotation about said axis in unison with said transfer turret and said mandrels, and a plurality of pusher members carried by said pusher turret in axial alignment with said turret pockets and said mandrels, and fixed cam means cooperable with said pusher members for cooperation therewith during the rotation thereof with said pusher turret to axially reciprocate said pusher
Claim 8
Dependent Claim
57 words
The apparatus of claim 3 together with an upright feed screw disposed adjacent to and at one side of said transfer turret for vertically spacing can bodies in accordance with the spacing of said turret pockets for transfer to said transfer turret, and drive means for driving said feed screw and said transfer turret in timed relation.
Claim 9
Dependent Claim
52 words
The apparatus of claim 6 together with a feed turret positioned between said feed screw and said transfer turret for feeding can bodies from said feed screw to said transfer turret, and means for driving said feed turret in timed relation to the driving of said feed screw and said transfer turret.
Claim 10
Dependent Claim
84 words
The apparatus of claim 3 together with an upright feed screw for vertically spacing can bodies in accordance with the spacing of said turret pockets for transfer to said transfer turret, a feed turret positioned between said feed screw and said transfer turret for feeding can bodies from said feed screw to said transfer turret, and drive means for driving said feed screw, said feed turret, said transfer turret, said sprocket and said pusher turret in unison, said drive means including said endless chain.
