IMPROVEMENT IN INKNG-APPARATUS FOR COLOR-PRINTm'G.

Be it known that we, THOMAS Moons. and PATRICK H DAY, of the city of Bloomington, in the county of McLean, and State of Illinois, have jointly invented a new and useful Machine for Improvement in the Art of Printing, said machine being a combined and variable ink-fount and distributing-table; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, referenc'e being had to the drawings, making a part of this speciiicatiomin which- Figure 1 is a perspective view of the table, marked A, distributing-strips, marked B, ink-fouuts, G, colorlifting springs, H, vsecured in place by the hinged catch'C, by the set-screws D, as arranged for work.

Figure 2 is a perspective sectional view of a separate strip, B, and the table A, with color-box G, and color-lifting spring, combined.

Figure 3 is a perspective view of a distributing-strip, B, detached from its color-box, spring, and seat in the table i Figure 4 'is a separate view of the color-box G, or receptacle for ink.

Figure 5 is a detached color-lifting spring, H, with its arch, h', semicircular iudentations, 1, 2 3, 4, and regulating-screw, i.

Figure 6 is a separate view of the hinged catch O and set-screws D, used to secure the strips in their seat in the table.

In the construction of this machine, the table A may be made of either wrought or cast-iron, of onef eighth or one-fourth of an inch in thickness, with ianges turned up at the sides, of a sufficient height (varying with the sizeof the machine) to secure rmly the strips. v

At the front end a iiange is also turned backward, to an acute angle, in order to lock firmly the grooved ends of the strips, when they are iitted over it, preparatory to being secured in their places, by the forward and downwardpressure of the catch C.

The strips B, iig. 3, may be made oi' Wrought or cas'eron, or type-metal, as the case may be, or as deemed preferable, the forward end rounded oii, to

afford easy passage to the inking-rollers, and having, near the rear end, a' recess, as seen at E, fig. 3, for the reception of the color-box G, and also at the extreme end, a threaded seat, for the screw t, seen in g. 5, and a notched recess, for the catch O.

These strips may be of variable lengths and heights, according to the size of press for which they are required, accurately squared and smoothed; but the face, or top B, must always be according to typestandard, varying from one line pica to as many lines pica required to suit the-letters in the formJ The color-box G, iig. `4, may be constructed of tin or zinc, preferably tin, of the size required to it'the stripsl and made movable, by having the bottom e2;- tended to itin grooves in the recess E, fig. A3,l or made immovable, and a part ofthe strip.

The color-lifting spring H, fig. 5, is made of steel, preferably, after the form shown in the drawing in which h is an arch, turned over the front end,

said arch having, in its rear side, one or two apertures, designated by the numeral 4, according to the color-boxes G are filled with ink, of any color desired,

placed in the strips B, and springs adjusted, as seen in the drawing, and then the form made up to correspond with the size of the letter in the type-form.

For division between the strips, quads or reglets either may be used.

Both forms being made up, the type-form is placed upon the press, in such position that the lines of letter are rolled lengthwise, the roller passing from the distributing-strips,,charged with in k, .directly over the lines of type.

A brief description of the operation ofthe machine, at work, is as follows:

The inking-roller passes lengthwise over the distribnting-strips, (see dotted lines, representing the roller,) and, striking the arches, forces the springs downward into the ink, which, `passing through the apertures 1, 2, 3, 4, is lifted up by the springs, and taken np by the roller, and distributed perfectly over the surface of the strips. They, in turn, impart the ink to the rollers which ink the type-form, distributing the color around their circumference, in parallel bands of color, thence to the type, in manifold colors, if desired.

By this method, as many vcolors as the fancy ofthe workman dictates can be limprinted, by one form and one impression, or one color onlymay be' used, with great saving over the common method, economy of labor, and improvement in the vart of chromo-printing.

This machine can also be used with a common handpress, and a great variety of card, job, and powerpresses.

Having thus described our machine and its operation what we claim as our invention, and desire to secure by Letters Patent, is

1. The construction of a-distributing-strip, cut to type-standard, a `lifting-spring, and color-box, as herein described.

- 2. Securing the strips in the table as herein spe'ci fied, by means of the clamp O and flange P.
