IMPROVEMENT IN INKlNG APPARATUS FOR PRINTING-PRESSES.

Specification forming part of Letters Patent No. 185,1 91, dated December 12, 1876; application filed April 22, 1876.

To all 'whom it may concern:

Be it known that I, ISRAEL L. G. RICE, of fCambridge, in the county of Middlesex and State ot' Massachusetts, have invented certain new and useful Improvements in Inking Apparatuses for PrintingPresses, which improvements are fully set forth in the following specification, reference being had to the accompauying drawings.

The object of the invention is to provide a printingpress with an inking apparatus for printing several colors from a sin gle form at one impression.

The invention consists in that system or mode of distribution of inks by placing` small disks into a sectional ink-table, the surfaces ot' the disks and table being level with one another; then, after these tables have been arranged to correspond with the lines ot' type to be printed, the press is started; and at'ter the'rollers pass over the tables, a turn is given l to the disks by seltacting mechanism, so that they present a different position to the rollers as they pass over them the next time.

A is the frame of the printing-press. B is the typebed. C C are sectional ink-tables. D D are disks. E E are shafts that are set in the frame of the printing-press, and on which are placed the belts F F to revolve the disks. H1 and H2 are ratchets on these shafts, and are acted upon by means ot' the bell-crank levers and pawls 1112, the action being as follows: When the swinging carriage J, that has the hiking-rollers, passes by the lever l1, it comes in contact with the end marked i', and strikes it and moves it along as it goes, and causes the ratchet to turn one tooth. This causes the shafts to turn a little, and the rubber belts upon them that pass in contact with the stems of the disks causes them to revolve a little. The action ot l2 is similar. It is best to have the movement take place when the rollers are not in contact with any of the disks; and it is also best to have the disks turn when the rollers are over the type-bed, and again when they have passed over the disks and are farthest from the platen. By doing this each disk will present a fresh portion of the surface to the rollers each time that they pass up and back. The hiking-rollers that pass over the form are shown at K K. L is the distributing-roller. This roller is in the roller-carriage M. This carriage is pivoted to the roller-frame J. A spring, N, connects the two together. This spring is fastened to J. Now, as J is moved so that the rollers pass over the type-bed, the spring N pushes the carriage M along, and allows the roller L to move up in the guidei'rame O until it strikes against the sectional tol'intain-rollers P P. The spring It now pushes the roller L oi the fountain-rollers, the rollers K K having moved ou so as to 'place the spring N in such a position that it does not hold the roller L against the fountain-rollers. The roller L is thrown by the spring R against the rapidly-revolving distributer S, this distributer being kept in motion by a belt from the main shaft ot' the machine passing over the pulley T. The sectional ink-fountains P l are placed in such a position that the operator may readily adjust the fountain knives or Scrapers pp by means of the rcgulationscrews without stopping the pressor leaving his position in front ot' it.

These movements and parts are clearly shown in the plan view, Fig. l, the sectional view, Fig. 2, and the carriage J, that holds the inking-rollcrs, and the carriage M, that holds the distributer, together with the connecting-spring N, that moves it backward and forward over the inking-tables, are clearly shown in Fig. 3.

I claim as my inventionl. The movable, interchangeable, sectional inktables ot' various widths, having disks inserted in them, substantially as in the manner and for the purpose herein set t'orth.

2. The combination ot'movablc, interchangeable, sectional ink-tables, provided with disks with movable, interchangeable, sectional inkfountains, substantially as in the manner and for the purpose herein set forth.
