IN KN G APPARATUS FOR FRlNTIllG IN COLRS.

T0 ALLMWHOM IT MAY (.lOIiTCHERhl': j

Be it known that we, GnoRenW. Woon and THOMAS L. Barinas, of Richmond, in vthe county of Wayne' and State of Indiana, haveinvented a new and useful improvement'in Inking Apparatus for Printing; 'and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making pnrt'of this specification, in which- Figure 1 is -aside elevation.

Figure 2 is a. vertical cross-section.

Figure 3 is a. side elevation of the inside of the frame.

Figure 4 is an elevationv of a. plate used in adjusting the rollers.

Figure 5 is an elevation of the inking sections.

Figure 6 is a perspective view of the adjustablejournal-boxes.

The same letters are employed in all the figures when indicating parts which are identical.

j'lhe followingsdescription will enable persons skilled in the art to construct and operate our improved inkf ing apparatus.l l A A'represents the frame of the'press, to which the inking apparatus is attached. M B B1B are thefuntain's. J have shown three; there may be more o r less. These are adjustab'ly attached to the frames "C, which aro'so attached to the frame that they may be removed if desired. The fountains are made adjustable, su that their relations to the oscillating s'oftrollers D may be regulated as required. E is an oscillating frame, so hinged thatait may be swung backward Aend-forwards automatically by familiar mechanism used 4in other inking apparatus fori-the purpose. To this frame the feed-rollers are attached, so as to turn freely on their journals. Metallic rollers Pmayv be so placed as to press against the soft feed-rollers D Dl D", an'dvserve to break the globulesfof ink taken by the feed-rollers from the rollers in front of the fountains, the latterbeing made to turn automatically by ordinary mechanism, so arranged as to turn them part of, a revolution when in contact y with the feed-rollers. This mechanism being in common use, is not shown. Other mechanism in common use, and thereforenot shown, is arranged to move the feed-rollers upon the oscillating frame E from the fountainsto and against the metallic distributors FFI F, which are rollers, the journals of which pass through'the-fratna G. vThe journal at one: end of the distributors has a thread cut upon it, working in a corresponding'female screw in the bearings, so thatby the reciprocating revolutionof distributors, they shallalso have a. longitudinal reciprocating motion, lfor the purpose of effecting a. more perfectdistribution of the ink. The bearings of the journals ofthe distributors are boxes ffl 2, `which are formed with double {hinges-upon .each side, fitting againstV p the sides lof the fra-me G, which is formed with slots, into which the bearingsffl are made to slide, being adjustably held in position, when in place, by set-screws passing throughthe plate G',Iwhich is lfastened by screws to the end of the frame G. `The ink is transferred from the-distributors to the transferring-rollers H. These rollers are made of wood and. covered with cloth. l Theirjournals turn in sliding-boxes,.constructed with iiahges on one side only, to rest against the inner faces o f frame G. Thesebearings, are slid-into the same slot (extended) which receives the bearings for the distributors. One end of thejournals of the transferring-rollers is extended beyond the frame to 'receive a driving-pulley.` These pulleys are shown at h twahe wooden p` transferring-rollers transfer the ink from the distributors to the adjustable nking-cylinders I, which are placed upon ,s shaft revolving in boxes, constructed like those of the transferring-rollers, and sliding in grooves out in the inner faces of the frame G in the extension of theline of the slots already mentioned. The width of these adjustnble'cylinders must be determined according to the breadth designed to be given to each color, and their positions on each shaft be xed accordingto the relative position of each color ou'the inishedjob. The spaces between' the inking-cylinders I I* I2 on the shaft are iilledradjustablyby the' collars z'z" l2which are of less diam,- eter than the inking-cylinders, made of various thickness, so that the inkingcylinders may be adjustably t arranged on each shaft, according 'to the requirements of the particular; job. Whenv they are all adjusted the fwhole roiler'is held in position by jam-nuts, turning on screws cut in the ends of the shafts. As eachset of inkng-cylinders I, ll, and I2 are intended to be applied to use in the transfer ofa distinct color, the will of course bo in such relative position that the cylinders of each set will come. between the planes of those of the., l other sets, and they should. project so far beyond the adjustable collars that the surface of the inlrinig-cylindeqh1
