Abstract
Abstract The washing roller of an offset printing machine is moved into circumferential engagement with the rotating blanket cylinder of the machine when the latter is to be washed, and a gear on the washing roller is thereby engaged with a gear rotated about a fixed axis on the machine frame for rotating the engaged portions of the roller and of the cylinder in opposite directions while they are also oscillated axially relative to each other and supplied with washing liquid.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
227 words
In an offset printing machine including a blanket cylinder having an axis; means for rotating said cylinder about said axis in a predetermined direction during operation of said machine; a washing roller having an axis substantially parallel to the axis of said cylinder; a frame supporting said cylinder and said roller; moving means for moving said roller toward and away from a position in which respective circumferential portions of said cylinder and of said roller are engaged in contact with each other; liquid supply means for applying a washing liquid to the circumference of said roller; the improvement which comprises: a. drive means for rotating said roller about said axis thereof in said predetermined direction, whereby said engaged circumferential portions move in opposite directions; and b. oscillating means responsive to the rotating of said roller by said drive means for oscillating said roller in the direction of said axis thereof, said drive means including 1. a first gear member secured to said roller for joint rotation, 2. a second gear member mounted on said frame for rotation about a fixed axis, and 3. actuating means for rotating said second gear member, said moving means moving said first gear member into and out of meshing engagement with said second gear member when said washing roller is moved into and out of said position thereof by said moving means.
Claim 2
Dependent Claim
227 words
In an offset printing machine including a blanket cylinder having an axis; means for rotating said cylinder about said axis in a predetermined direction during operation of said machine; a washing roller having an axis substantially parallel to the axis of said cylinder; a frame supporting said cylinder and said roller; moving means for moving said roller toward and away from a position in which respective circumferential portions of said cylinder and of said roller are engaged in contact with each other; liquid supply means for applying a washing liquid to the circumference of said roller; the improvement which comprises: a. drive means for rotating said roller about said axis thereof in said predetermined direction, whereby said engaged circumferential portions move in opposite directions; and b. oscillating means responsive to the rotating of said roller by said drive means for oscillating said roller in the direction of said axis thereof, said drive means including 1. a first gear member secured to said roller for joint rotation, 2. a second gear member mounted on said frame for rotation about a fixed axis, and 3. actuating means for rotating said second gear member, said moving means moving said first gear member into and out of meshing engagement with said second gear member when said washing roller is moved into and out of said position thereof by said moving means.
Claim 3
Dependent Claim
15 words
a second gear member mounted on said frame for rotation about a fixed axis, and
Claim 4
Dependent Claim
15 words
a second gear member mounted on said frame for rotation about a fixed axis, and
Claim 5
Dependent Claim
58 words
In a machine as set forth in claim 1, a rubber coating constituting said circumferential portion of said washing roller, said liquid supply means including a container and filling means for filling said container with washing liquid, said rubber coating dipping in said liquid when said container is filled with liquid and said rubber coating engages said cylinder.
Claim 6
Dependent Claim
44 words
actuating means for rotating said second gear member, said moving means moving said first gear member into and out of meshing engagement with said second gear member when said washing roller is moved into and out of said position thereof by said moving means.
Claim 7
Dependent Claim
44 words
actuating means for rotating said second gear member, said moving means moving said first gear member into and out of meshing engagement with said second gear member when said washing roller is moved into and out of said position thereof by said moving means.
Claim 8
Dependent Claim
25 words
In a machine as set forth in claim 1, said moving means including yieldably resilient means for urging said washing roller toward said blanket cylinder.
Claim 9
Dependent Claim
76 words
In a machine as set forth in claim 3, a hanger pivotally mounted on said frame, said roller being mounted on said hanger for rotation about said axis thereof, said yieldably resilient means engaging said hanger and urging the same to pivot in a direction to move said washing roller toward said blanket cylinder, said moving means further including cam operated motion transmitting means for pivoting said hanger against the urging of said yieldably resilient means.
Claim 10
Dependent Claim
212 words
In a machine as set forth in claim 4, said motion transmitting means including a cam member mounted on said frame for movement about an axis, said cam member having a substantially circularly arcuate face about the axis thereof and being formed with two communicating recesses of different radial depth in said face, a cam follower member mounted on saiD frame for movement along said face and into and out of said recesses when said cam member rotates about the axis thereof, means linking said cam follower member to said hanger for movement of said roller from a rest position remote from said cylinder, in which said first and second gear members are disengaged, to an idling position remote from said cylinder, in which said gear members are engaged for rotating said roller, when said cam follower member moves from said face in the recess of smaller radial depth, and for movement of said roller from said idling position into a working position when said cam follower member moves from said recess of smaller depth into the recess of greater radial depth, in said working position of the roller said gear members being engaged and said circumferential portions being engaged, and operating means for rotating said cam member about the axis thereof.
Claim 11
Dependent Claim
161 words
In a machine as set forth in claim 5, a guard member mounted on said frame for rotation about said axis of the cam member axially adjacent the cam member, said guard member having a substantially circularly arcuate face portion coaxial with said face of the cam member and of substantially the same radius, biasing means interposed between said cam member and said guard member for turning said guard member into an angular position in which said face portion and said face jointly form a substantially complete circle about the axis of the cam member and movement of said cam follower member into said recesses is prevented, and cooperating abutment means on said cam follower member and said guard member for moving said guard member away from said angular position thereof against the force of said biasing means when said cam member is turned in one direction and for thereby permitting sequential movement of said cam follower member into said recesses.
