INK DISTRIBUTION FOR PRINTING-PRESSES.

Specification of Letters Patent.

Patented Jan. 18, 1916.

Application filed April 22, 1914. Serial No. 833,579. 1

for Printing-Presses, of"'which'='the following is a specification.

The principal objects of the invention are the provision of an improved system of ink distribution under which the ink is more uniformly applied to the cylinder at the points of contact therewith of the form rolls, and the mounting of the form and rider rolls in such manner as to be readily brought into accessible position for cleaning, adjustmentand the like.

Other advantageous features of construction and operation will be made apparent to those skilled in the art from a reading of the subjoined detailed description taken in connection with the accompanying drawin upon which the description'is predicate and in which. for purposes of illustration only, is set forth in side elevation a preferred embodiment of the invention.

, In that form of construction chosen as an example the numeral 11 designates the plate or form cylinder upon the axle 12 of which is loosely mounted the collar 13 forming an integral part of aframe designated generally at 14. This frame is in the form of a segment and has sultably journaled upon its periphery a plurality of trains of rolls, one train comprising the form rolls 15 and 16 and, the rider rolls 17,' 18 and 19, While the other train comprises form rolls 20, 21 and 22 and rider rolls 23, 24, 2'5, and 26. The form rolls of the two trains are driven from the cylinder gear 27 at a peripheral speed corresponding to that of the cylinder by means of

pinions

28, 29, 30 and 3l.suitably geared to the form rolls.

In order to effect a supply of ink in proper degree to both trains of rolls the final ink drum 32 of the ductor train has mounted upon its axis 33 the bearing yoke 34 of a ductor roll 35 which latter is caused in any suitable manner to oscillate upon the axis of the drum with the ductor roll and ink drum in continual peripheral contact, the periphery of the ductor roll contacting alternately with the periphery of the

first rider rolls

19 and 26 of each of the distributing trains respectively wherebythe ink from the drum is supplied independently to the two trains instead of indirectly to one of the trains through the other, as has been common.

In order to provide for the simultaneous adJustment of the rolls of each train in their relation to the form-cylinder and to throw all of the rolls simultaneously out of operative engagement with the said cylinder the frame 14 is provided with an eccentric 36 suitably mounted upon an axis 37 and arranged to bear upon the fixed wear block 38. The eccentric has connected thereto the lever arm 39 which in turn is connected by a link- 40 with a lever 41 fulcrumed at 42. By throwing the lever 41 to the right the frame together with the trains of rolls are lifted bodily out of contact with the form cylinder and with the driving pinions out of mesh with the cylinder gear.

In order to bring the distributing train of rolls into a position readily'accessible for cleaning, adjustment, or for other purposes provision is made to rotate the frame and trains of rolls bodily about the cylinder, the frame being provided for this purpose with a segment rack 43 in mesh with a pinion 44 which latter is adapted to be manually rotated by any suitable means, as for instance a crank engaging the squared end 45 of its shaft. By the rotating of the pinion 4-1 the frame and the trains of rolls will be caused to describe an arc to the right, as viewed in the drawing, s as to bring the rolls clear of the printing press frame into a position of readv accessibility. I
