IMPROVEMENT IN INKING-APIARA'IUS FOR. COLOR-PRINTING.

TO AIIL WHOM IT MAY OONCERN Be it known that I, GEORGE W. WOOD, of Richmond, in the county. of Wayne, and State of Indiana, have invented a new and useful Improvement in Inking-Apparatus for Printing in more than one Color; and I do hereby declare that the'following isa full, clear, and exact description of the saine, reference being had to the annexed drawings, making part of this specication, in which- Figure 1 is a perspective view ofthe frame and bed.

Figure 2 is a perspective view of the inking-rollers and frames attached.

'Figure 3 is a side elevation of the operating-mechanism, and

Figure 4 shows the tablets for receiving the ink from the distributing-rollers.

The same letters are employed in all the gures to indicate the same parts. u

This invention is intended for application especially to cylinderjoh-presses, but is also readily adapted to what is commonly known as the Adams book-press. v

A represents the frame ofthe press; B is the reciprocating bed, the form being placed on it at B.

1 On each side of the bed are placed the permanent ways C. The adjustable inking-tablets, D DI D, con= structcd as shown in g. 4, are also placed on the reciprocating bed, beingproperly adjusted in sets parallel with one another, corresponding with the number of colors to be printed, each set receiving one color, and they being respectively disposed, according to the colors intended to be printed, upon the lines of type with which they correspond.

The ink is received from the distributing inking-tables E El E2, also resting on the bed B. Instead of these tables, inking-fountainsmay be used, which would. be attached to the ways C.

F is the frame ofthe inking-rollers, supported on the Ways O. I-I, III, and H2 are the hard hiking-rollers, which, if fountains are used, would receive the ink. Gr Gr1 G2 are the distributing-rollers, which rest upon grooved pulleys on their shafts, running on the ways C.

The number of these parallel ways on each side corresponds with the number of distributing-rollers, so that each shall run on its own track. v

The shafts of these rollers pass through'eyes in the pulleys, allowing them longitudinal reciprocatingmovc p ments, received from the spirally-slotted cams K in the usual manner.

In order that each distributing-roller.shall receive its own appropriate color, depressions are formed in the ways, opposite the ends of the inking-tables E E1 E2, from which thcseveral rollers are respectively to receive their. color, so that in traversing the ways, each roller shall be brought into contact with the face of' its-'own table, and pass over the others without touching them. In the same manner, dcpressionsare formed in the ways opposite the inking-tablcts D D D'so that the roller intended to communicate its colorto the-set of tablets shall comeA in contact with their faces, and pass above the others without touchingthem. By this means each distributing-roller receives only its own color, and transfers it to its own set of tablets. The type-inking rollers L I1, attached also on the frame F, traverse the length of all the tablets twice, receiving from them the colors disposed on said rollers in bands correspon-ding with the lincsio't` type to which said colors are respectively transferred'. I

In the ordinary inking-apparatus of this class forprinting in one color, the inking-rollers are stationary, and the bed has a reciprocating motion over a space about twoand a half times the width of the form.. In order to make the traverse necessary for the increased length incidentfto this apparatus, it is necessaryy to commuuicate a reciprocating motion to the rollers at an accelerated speed. This is effected bythe following mechanism v The bedreceivingits reciprocating motion in the usual manner, a rack, M, attached to t he.side ofthe bed,

meshes intoa small pinion, N, formed on the hub ofthe larger pinion, N', which meshes into a rack, O, on the p side of the roller-frame'F, so that as the bed moves in one direction, it drives the roller-frame at an :accelerated speed in the opposite direction. Y

This compound pinion turns upon a spindle-upon the upright Z, secured firmly to the frame of tbe press.

It has no motion of its own, except that of revolution.

v This arrangement of mechanism saves most of the power which would be necessary to move tbe heavy bed with the form over a greatly-increased space.

The rollers H HYH2 have their bearings on the frame F,the rollersG GL Gr2 have theirs on the ways C, being connected with the shafts ofthe rollersH H1 H2 by oscillating-arms, through which the journals of both rollers pass, so as to allow the rollers G G1 G2 to accommodate themselvest-o the irregularities in the face of the ways.

A' rack may be attached to the ways C, to gear into pinions on' the shafts of the rollers H H' H2, to communicate a positive motion to the rollers.

What I claim as my invention, and desire to secure by Letters Patent, is 1. The combination of the Areciprocating bed B, ways C, adjustable tablets D Dl D2, and rollers Gr G1 G2, substantially as described. i 4

2. The'combination of the reciprocating bed B and roller-frame F, so connected by intermediate mechanism that the movement of the former shallV communicate motion to the latter in an opposite direction, substantially as and for the purpose sot forth.y Tn testimony whereof, I have signed my name to this speciication-in the presence of two subscribing witnesses.
