IMPROVEMENT 'IN INKING-APPARATUS FOR PRINTING-PRESSES.

TO ALL WHOM IT MAY CON CERN Beit known .that I, THOMAS L. BAYLIES, of the -city of Richmond, and State of Indiana, have invented al new and useful Improvement in Inking-Apparatus for Printing-Presses; and I do hereby declare that the followingis a fuILclear, and exact description thereof, reference being had to the accompanying drawings making a. part of .this specification, in which- Figure 1 is a perspective view,

Figure 2 is a side elevation, and

Figure 3 a transverse section.

The same letters in the diiierent gures relate to corresponding parts of the apparatus.

My invention relates to an inking-apparatus foriprinting in dierent colorss and consists in a novel arrangement of parts, whereby the supply-rollers attached t'o oscillating-bars may be moved so as to permit the proper intermediate inking-rollers to be brought into contact with their own peculiar supply-roller, each one receiving its own peculiar color, to be transferred to its own set ot' color-strips, from which the colors are takenin bands upon a type-inking roller, and transferred to a single form, from which theljob is printed at asingle impression.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A and A' represent the sides of the structure.

E representsithe form, and a' and b' are lines ot' type.

C is the type-roller, and B and D are inking-rollers.

a and 6 are color-strips.

The type-roller Cand inkingrollers B and D have their bearings in the slotted ends of the two sets of' arms, F and F', each set of which arms is connected together, and is secured on the ends ot roller V.

e represents rubber bands, by which the rollers O, I5, and D are held in their positions (in a flexible manner) in the slots of arms F and F'. l l i The hiking-rollers B and D receive their 'respective colors from rollers YB' and D', between which latter and the color-strips they are made to alternate, thus giving the inking-rollers B and D, and type-roller O, a simultaneous reciprocating motion on roller V, type-roller O, inthe operation, being made to alternate over color-strips a and b, and lines of type a' and b'. Thus the colors are transferred to the color-strips by rollers B and D, from which color-strips, typeoller O receives the colorsA in bands, and inks the lines of type, which latter correspond in position with color-strips 6F the saine color. l

The upright'bars N and N', in which rollers B and D have their bearings, arcpivoted at H and H', and are secured llexibly in a vertical position, resting against the apparatus., by rubber bands e'.

As the inliing-rollers and D are brought down in contact with their respective supply-rollers B' and D', roller D is prevented from-coini"ng in contaetwith roller B' by means of the tripping-collars I and I' striking projections Qt'nnd u, and thus forcing,r the bars N and N' and their rollers back until roller D has passed.

Roller D, in its operation, is lifted over color-strips a by means of the elevating-strips IJ, thus preventing the mixing of difierent-colored inks. The roller D, being reduced in din-meter opposite to strips JJ, is not affected in its motion by the latter. 4

A handle is situated at t, by which a convenient hold is afforded for operating the inking-1'olle1s.

Two colors only are shown in this example. A greater number may be used by further duplicating the mechanism.

The bed or table on which the color-strips are placed is permanently located in thel apparatus ofthe accompanying example, and is arched so that the position of the color-strips conforms, or nearly so, to the are described by the inking-rollers in their reciprocating movement.

.r and r are stops, for regulating the movemcnt'of the type-roller in a downward direction.

\ 2 l Y y .r

ollers B and D, for the purpos of lateral distriliution of inkhtnay be prvided with the nrdithem a reciprocating motion longitudinally.

The rollers B and D are supplied withink fronn fountains, or in any manner usually adoptecl.

Having th'us fully described my said invention, what I claim, and desire to secure by Letters Patent, is-- In c'ombination with the oscillating slottedarms F,.roller.s` B G D, springsra, and tripping-collars I I', the rollers B D', upright bars N, projections u, and springs', arranged in relation to ne anather, so as to operate substantially in themanner and for the purpose set forth.
