Abstract
Abstract Apparatus for mounting an ink roller so that it may be shifted into engagement or disengagement with a form cylinder roller in an offset press. The apparatus comprises a holder for journalling the ink roller on a supporting frame, the holder being mounted so as to be reciprocally movable on said frame along a path radial to the axis of the form cylinder and an ink distributing roller to which it engages. The holder and frame are provided with engaging bearing means. A rod slideably extends through the holder parallel to the radial path of movement and has stop means limiting the relative upward and downward movement of the rod through said holder. Means are provided for reciprocating the rod in response to the selected operation of the machine whereby said holder can be listed and swung to cause the ink roller to engage and disengage selectively with the form cylinder and the ink distributor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
165 words
Apparatus for mounting an inking roller with respect to a form cylinder mounted for rotation about its central axis and an ink distributing roller mounted parallel therewith comprising a supporting frame, a holder mounted for reciprocal movement on said frame along a path radial to the path of said form cylinder, said roller being journalled in said holder for rotation about its axis parallel to the axis to said cylindrical member, a surface inclined to the radial direction formed on the exterior of said holder, means mounted on said supporting frame and bearing against the inclined surface, an elongated guide rod slideably extending through said holder parallel to the radial path of said holder, stop means limiting the relative reciprocable movement of said guide rod through said holder, and means for reciprocating said guide rod in response to a selected operation whereby said holder is caused to selectively carry said roller into and out of engagement with said form cylinder and said ink distributing cylinder.
Claim 2
Dependent Claim
165 words
Apparatus for mounting an inking roller with respect to a form cylinder mounted for rotation about its central axis and an ink distributing roller mounted parallel therewith comprising a supporting frame, a holder mounted for reciprocal movement on said frame along a path radial to the path of said form cylinder, said roller being journalled in said holder for rotation about its axis parallel to the axis to said cylindrical member, a surface inclined to the radial direction formed on the exterior of said holder, means mounted on said supporting frame and bearing against the inclined surface, an elongated guide rod slideably extending through said holder parallel to the radial path of said holder, stop means limiting the relative reciprocable movement of said guide rod through said holder, and means for reciprocating said guide rod in response to a selected operation whereby said holder is caused to selectively carry said roller into and out of engagement with said form cylinder and said ink distributing cylinder.
Claim 3
Dependent Claim
57 words
The apparatus according to claim 1 wherein said means for reciprocating said rod comprises a cam moveable in response to the selected operation of said machine, a cam follower, resilient means urging said cam follower into contact with said cam, link means interposed between said cam follower and said rod for connecting said follower to said rod.
Claim 4
Dependent Claim
77 words
The apparatus according to claim 2 wherein said cam is provided with a contoured profile adapted to cause said guide rod to move said inking roller between a first position out of contact with said ink distributing roller and said form cylinder, an intermediate position whereby only said inking and ink distributor rollers are in contact and a second position where said inking roller is in contact with both said ink distributor roller and said form cylinder.
Claim 5
Dependent Claim
93 words
The apparatus according to claim 1 wherein said stop means comprises a collar secured to the end of said guide rod above said holder and a compression spring located below said holder normally urging said holder into resilient abutment with said collar, an adjustable screw extending through said collar and bearing against the end of said holder, a pin secured to the holder and extending transversely through a vertical slot in said frame and adjustable means for capping said pin through said slot thereby permitting reciprocal movement of said pin in said slot.
Claim 6
Dependent Claim
19 words
The apparatus according to claim 1, wherein said means bearing against said inclined surface comprises an adjustable screw member.
