Inking roller assembly

Claim 2

In a printing machine: a shaft; an inking roller carried by said shaft; means for rotably supporting said shaft including a holder having a pair of spaced side walls and an end wall between said side walls; said holder being formed with a detent lug and at least one stop lug on said end wall; and a bracket having a pair of spaced bearing arms which are adapted to receive and support the respective ends of said shaft so that said inking roller is disposed between said arms and an end wall between said bearing arms; said bracket being formed with a detent tongue on said end wall that is adapted to yieldably cooperate with said detent lug and with a stop edge that is adapted to cooperate with said stop lug whereby said holder and inking roller may be detachably mounted on said bracket.

Claim 3

Apparatus as defined by claim 1 wherein said bracket is provided with open slots into which said end portions of said shaft are inserted prior to the pivoting of the holder to a final assembled position on said bracket.

Claim 4

Apparatus as defined by claim 1 wherein said shaft and said opposed spaced walls are formed to accommodate bodily movement of said shaft into assembled position on said holder with said roller between said walls, and the ends of said shaft beyond said walls shaped to enter slots formed in said bracket.

Claim 5

An inking roller assembly adapted to be used in a printing machine having a rotatable printing drum, and a bracket secured to said printing machine, said bracket having detent means and a stop means thereon: comprising an inking roller; an inking roller holder including opposed spaced side walls between and on which said roller is received for rotation; said bracket having parts adapted to releasably engage said inking roller holder; detent means on said inking roller holder adapted to coact with the said detent means on said bracket; a stop on said inking roller holder and adapted to coact with the said stop means on said bracket when said inking roller holder is in its assembled position on said bracket, in which position the periphery of said inking roller is positioned to contact the printing surface of said rotary printing drum; said inking roller holder including a shaft on which said inking roller is rotatably mounted; and said parts of said bracket being adapted to releasably engage inking roller holder including means engaging said shaft for allowing said roller holder to pivot about the axis of said shaft relative to parts of said bracket when said bracket is in releasable engagement with said inking roller holder.

Claim 6

An inking roller assembly adapted to be used in a printing machine having a rotatable printing drum, and a bracket secured to said printing machine, said bracket having detent means and a stop means thereon: comprising an inking roller; an inking roller holder including opposed spaced side walls between and on which said roller is received for rotation; said bracket having parts adapted to releasably engage said inking roller holder; detent means on said inking roller holder adapted to coact with the said detent means on said bracket; a stop on said inking roller holder and adapted to coact with the said stop means on said bracket when said inking roller holder is in its assembled position on said bracket, in which position the periphery of said inking roller is positioned to contact the printing surface of said rotary printing drum; said inking roller holder including a shaft on which said inking roller is rotatably mounted; and said parts of said bracket being adapted to releasably engage inking roller holder including means engaging said shaft for allowing said roller holder to pivot about the axis of said shaft relative to parts of said bracket when said bracket is in releasable engagement with said inking roller holder.

Claim 7

The machine of claim 4 wherein said holder detent means resist the force exerted by said rotary printing drum which tends to rotatively force the inking roller holder out of operative engagement with said bracket.

Claim 8

The machine of claim 5 wherein said inking roller holder includes a finger piece extending in the direction away from said printing drum, thereby permitting pressure to be exerted on the inking roller holder in such a manner as to overcome the coaction Of said holder detent means and said bracket detent means.
