"dilated sty@- .States ISRAEL L. G RICE, OF CAMBRIDGE, MASSACHUSETTS.

Letters Patent No. 89,244,'datecl April 20, 1869.

The Schedule referred to in these Letters Patent and maldng part o! the Ilmo.

To all whom 'it may concern Be it known that I,IsRA EL L. G. Rien, of (lam` bridge, inthe county of Middlesex, State of Massachusetts, have invented a new and useful Machine for Distributing Printing-Inks of Various Colors on Lines of Printing-Types, so that several colors may be printed at one impression; and I do hereby declare that the following is a full and exact description thereof, reference being had-to the accompanying drawings, and to the letters of reference marked thereon, making a part of the specification. Y

The nature of my invention consists in providing distributing-rollers of various widths, with distributingdisks of corresponding diameters, placed at right angles and impinging upon them, by means of which I am enabled to put upon lines of printing-types, inks of any desired colors, and to print at one impression on the same sheet, several colors To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my distributing-rollers, as shown in the accompanying drawing, marked a. a a, of rubber or other suitable material, and of different widths, according to the different sizes of types, and through their centres, I make holes so that they may be placed on the shaft e.

On this shaft, I cut a screw-thread, and place a nut, b. 0n the other end, I place a collar, b".

The rollers are held in their proper position by divisional rollers c c c, of less diameter, and a variety of widths. These are pnt between the distributing-rollers to separate them, and between the rollers and the collars. b" The nutb is-then turned so they are pressed against the collar, and are made to turn with the shaft e.

The disks d d are made of metal, and their diameters are a little larger than the widths of the rollers, and are furnished with astem, or journal, f.

The object of these disks is to evenly distribute, vibrate, or spread the different colored inks, which are 'upon the distributing-rollers c a a. They accomplish their object by beingplaced at right angles with the distributing-rollers, and pressing against them, and revolving simultaneously with them. The face of the disk is smooth.

The carriage A is provided with two spring-catches, g g, to hold the shaft in its place. The carriage has also numerous 'holes through the upper part, which serve as bearers to the stems, or journals of the disks d d.

To turn these disks, an endless belt passing between the rollers w fw, which keep it in place, and the stems or journals ofthe disks, causes them to revolve.

Motion is given to the belt k, by means of the toothed rack a, which 'is secured to the frame B, and which moves backward and forward beneath the carriage A, working in the toothed wheel m, which, as it turns, moves the bevel-wheel o', it being secured to the same shaft.

The bevel o' turns the bevel-wheel o, which has a pulley, fr, attached to its shaft.

The frame B is made of metal, and is madeto correspond to a larger one, made for a Gordon Franklinpress. It is made to furnish a means to hold the inking-tables, and for the inki'ng and distributing-rollers to work on.

The two ends D D are fastened to that part ot the press directly above the bed of the press, over which the ink-rollers move. n

The frame B occupies the same position the ink-taf' ble does, when it is on the press. The carriage A is 'placed above the frame B, the two guides of the carriage resting in the grooves in the frame. The earriage is held in one position by two connecting-rods, or any other suitable means. The rods may be fastened to the printing-press. The ordinary mechanism of the press gives a reciprocating motion to the frame B. The toothed rack u, working in gear with the toothed wheel m, being secured to the frame B, gives thc required motion to revolve the disks.

The inking-table is made in sections, H H, of equal length but of different widths, to correspond with the distributing-rollers.

I place a clamp, F, furnished with thumb-screws, at each end of the inking-tables.

The inking-rollers are made similar to the distributing-rollers, with a hole through their centre, and of various widths, to agree with the distributing-rollers, and are slipped on a shaft. These rollers are on the printing-press, and are not shown. It is not absolutely necessary that the hiking-rollers be in sections. This is merely suggested. The inks of different colors may be applied directly to the distributing-rollers by means of a pallet-knife, in place of a fountain. They have also divisional rollers of smaller diameters, and the shafts have a collar and uut, like the distributing-rollers. A. fountain, having movable partitions to keep the several colored inks apart, is also used.

When the form is ready to be printed, I arrange my inking-rollers so that there will be one for each color, placing the divisional disks, washers, or rollers between, to keep them the properk distance apart on the shaft. I then place my ink-tables H H in relative positions to them. It may be advantageous to have divisional tables of less height, to arrange the inking-tables more rapidly. These tables may be made ofthe same width as the divisional washers, or disks, and thus the necessity of measuring the distances the ink-tables should be from one another may be avoided; as, in printing a form, the space between the inking and distributingrollers and the ink-tables, should be the same.. I then arrange my distributing-rollers c c, by means of the divisional rollers, so they are kept the/ir distance apart. The disks are then placed in the carriage A, their stems, or journals ff are put through the holes which serve them for boxes, or bearers, and under the belt k, and at right angles with the distributing-rollers, against which they press. These disks may be turned by means of gear-Wheels, placed on each stem, or journal, and the disks themselves be separate from the stein, or journal, but, by having them keyed, may be put on to the journals, and made to revolve.

A spring may be used, of spiral form, to keep each disk pressed gently against the distributing-rollers. The inks are then placed in the fountain, each color in its compartment relative to the distributing-roller which is to receive it. Y 'The sectional ink-fountain is placed above the distributing-rollers, and iu any suitable position so the distributing-rollers may come in contactwith it, so as to continually receive a supply of ink, or so as to take a little ink at each impression, as may be required.

The fountain, or rather the sectional roller inside the sectionalink-fountain; is given motion by mechanism connected with it and the printing-press.

By the above-described mechanism, as the disks revolve they distribute evenly the inks upon the distributing-rollers, the distributing-rollers distribute it upon the ink-tables, the hiking-rollers then put it upon the types, so that a great many colors may be printed at one impression on the same sheet.

The apparatus for distributinpr maybe applied to :any press, although rollers would, in some cases, take the place of the sectional tables, so that, perhaps iu some instances, the distributing-disk would be applied direct to the hiking-table, and the disks would be made of some other material than metal.

What l claim as my invention,and desire to secure by. Letters Patent, is-

The application of distributing-disks, placed at right angles with distributing-rollers, or hiking-rollers, or hiking-tables, substantially as and for the purpose set forth.
