IMPROVEMENT IN INKING ATTACHMENTS FOR CHROMATIC PRINTING.

Specification forming part of Letters Patent No. 139,155, dated May 20, 1873 application filed April 1, 1873.

To all whom it may concern:

Be it known that I, E. A. Howrrr, of White- Water, in the county of Walworth and State of Wisconsin, haveinvented certain Improvements in Inking Devices for Chromatic Print- .ing, of which the following is a specification:

This invention relates to an ink-distributing device for chromatic printing, as is more fully hereinafter set forth.

In the drawing Figure 1. is a top "iew, and Fig. 2 a longitudinal vertical section.

A represents the oscillating ink-distributing I table of a common Gordon or Liberty press,

. simple set-screw at its rear end, bearing against the frame as best seen in Fig. 2; or it may be moved laterally thereon when a blendin g of its color with that of the next one is desired. The fountains are removable from the straps so that the color of a given strap may be changed without removing it from the frame. They may be secured by simple screws, or by dovetailed or similar holders. The fountains partially encircle the fountain-roller, so that, when their straps are moved, they may preserve close contact with said roller. Upon the end of the fountain-roller I provide a cam which bears upon a suitable projection fixed to the stationary frame of the press, whichis actuated in the present instance, by a ratchet and paw], deriving movement from the workin g parts of the press, by which the roller is intermittently rotated to supplyink, and the frame intermittently reciprocated to present a constantly changing ink-distributing surface for the type-rollers.

It is obvious that any other arrangement of the devices for reciprocratin g the frame may be employed without departing from the spirit of my invention, which is to accomplish a reciprocating movement of the ink-distributin g straps at each reciprocation of the typerollers over them.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A chromatic inking device, consisting of a series of ink-distributin g straps, fountains, and ink roller, so combined with a printing press as to have a lateral reciprocating movement, as described.

2. In combination with the series of inkdistributing straps, the series of detachable ink-fountains, as described.

3. The ink-distributing straps and fountains, so constructed as to be independently adjustable, laterally, upon the frame, as described.

E. A. HOWITT.
