To all whom it may concern:

Be it known that 1, Joan H. SCHUSSLER, a citizen of the United States, residing at Chi, cago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Vibrating Distributing-Rollers for Plateau-Presses, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. I

My invention relates in eneral to printing presses, and more particuTarly to means for distributing the ink upon the inking rolls of a platen press. I

In order that the inking rolls of printing presses may apply ink to the printin surface evenly and uniformly, it is desira le that means should be provided for" distributing the ink smoothly over the rolls. By providing such ink distributing means a higher grade of work may be done and greater speed attained owing to the more uniform application of the ink to the printing surface.

The. primary object of my invention is to provide a platen printing press with a roll for uniformly ink upon the inking rolls during the entire movement of the inking rolls relatively to the inking disk and printing surface.

A further object vide an ink distributing roll for platen printwhich will be simple in construction, inexpensive in manufacture, and eflicient in use. My invention as hereiii disclosed may be generally described as comprising a shaft rigidly supported above and intermediate of a pair of inkin rolls of a platen printing press, an ink distributing roll mounted upon the shaft and engaging the surfaces of the pair of means for moving the dis tributing roll axiallywith relation to the inking rolls during their entire movement over the ink supplying disk and over the printing forms, and in which,-

B desi nates the inking roll carriage at one side of t e press which supports the inking rolls. The carriage Bis pivoted at b in the usual manner.

O & C indicate spring-supported rods carried by the frame B at each side of the press. The rods C support at their upper ends plates 0 in which are j-ournaled the ends ofa The upper ends pair of inking rolls D D of the rods C support the brackets in which arpl j lgurnaled the ends of an auxiliary inking ro The construction above described is well itself no part of my inknown and forrnsjin vention, but is merelyshown for convenience in order that the construction of my improvement may be fully disclosed. It is obvious that my invention may be applied to other forms of platen printing presses than the one illustrated.

Referringmore particularly to Figs. 2 and 3, reference character F indicates a shaft si-i ported above and intermediate of the pair of inkingrolls D 11?. The ends of the shaft F are surroundedb latter being 'mounted in bearings F E rigidly secured to the brackets c c. A clai'n screw f extends through the top wall of sec. of the beari s 1F into contact with the inclosed block The ends of the shaft Fare nonrotatably' secured within the respective blocks F by means of cotter ins f -WlllGh extend through re isteri-n ladies in t shaft.

mounted upon the shaft F. Secured within one end of the roll E is a ring E having an interior screw thread engaging the screw thread on a sleeve G. The sleeve G loosely surrounds the shaft F and eng es at one end a collar 9 fixed to the shaft; he end of the sleeve G within the roll E is provided with a disk G which serves as one member of a clutch. G indicates a disk which serves as the other member of the clutch and which is provided with a hub having slots therein istribu'ting roll indicates the printing surface and A the inkand operation boxes F W, the

'g. 3.- A radial pin g is carried by I the outer end thereof sleeve G adjacent while a second radial pin 9 is carried by the 10 sleeve G at the inner end of the screw thread thereon. v

The operation of the embodimentof my invention above described is as follows: When the inking rolls are in. the position shown in Fig. 1', the carriage B is oscillated in the usual mannerso that the rolls will pass over the inking disk A printing surface A. oscillated injaireverse direction which causes the inking rolls to travel upwardly over the and thence over the printing surfacethence over theinkingdisk to the position shown in Fig. 1 During such travel of the inking rolls they are rotated and throu h their engagement with the surface of the istributin roll the latter is a rotated about the shaft As the shaft F is fixed the roll E rotatesjrelatively thereto and owing to the enga ement between the screw-threaded sleeve shaft and the, interiorly screw-threaded rin E, fixed Within the roll, the latter is moved axially'with respectto theshaft coincidently with its rotation about the same:

inkin rolls are atthe op osite end'of their trave from the positions own in Fi 1, the 'distributin roll is in the position relative to the shaft shown in Fig. 3, thatis, thepin e engages at itsouter end with the radial pin 9'. As theinking rolls travel upwardly the -distributing roll willbe rotated relatively to the shaft in a reverse direction and hence will be moved axially towards the right in in e"en-. in'g Should t e pin e" Fig. 3 until the inner end of the gages the radial ip engage pin g be ore the inking rolls reach t e upper end of their travel and the dis- .tributing roll consequentl be further .ro-

tated with respect to the-s aft F, the sleeve G will move with the rolls and relatively to the, shaft, such movementbeing permitted by "'a' slippin G & G Wh position shown in Fi pin e is in contact with the in g and during the downward movement of left until the outer endof the i plin eengagesi the radial pin 9 whenany rther movement of the roll u on the shaft will move with-it the-sleevei such movement permitted by the clutch member vGslipping with respect to .clutch member G.- embodiment of my invention it ,will be observed that the two membersof the clutch may be held in contact with any desired H surrounds the sha t gets at each side thereof as clearly shownin- ,The carriage B is then clutched on the When the Letters Patent is: I

1. The combination with a platen printing between the clutch members en the inking rolls are in the. 1 the inner end of the press having an inking the inkin rolls the distributing roll will move towar s the being In this screws f serve to regulate the pressure wit which the distributing rollengages the surfaces of the inking rolls. Changes in temperature as well. as usage necessitate an-adjustment of the screws f in order that the contact between the distributing roll' and inkin'g'i'olls Will be such as to evenly distribute the ink. p

.It will benoticedthatthe inner ends of the boxes F are provided with flanges f 3 which over-lie the adjacent edges of F. By making the boxesaxially movable upon theshaft it is possible to employ closed brackets inasmuch as the boxes, may be moved along the shaft to positions within the brackets and there retained by reason of the flanges on the sides of the brackets and the cotterpins on I The cotterpinsl-lserve not only to retain the boxes withboxes engaging the inner the outer sides of the brackets.

in t e brackets, "but also to rigidly connect the ends of the shaft to the boxes.

From the foregoing description it will be observed that I have invented an improved form ofdistributingroll for platen printing presses in which the ink will be smoothly distributed upon the inking rolls owing to the continuous axial movement of the distributing roll relativel to the inking rolls during the entire traveof the latter relatively to the inking disk and printing surface.
