Specification of Letters Patent. Application filed Septemhetll, 1909.

To" all'wiwm it may concern:

Be it; known that I, Minimal. AI Dnorrcoon, of Chica o, in the county of Cook-and State of Illinois, have invented certain. 'nenand useful Improvements in Inking Appara tus for. Printing-Presses; and I'.l1ereby dcclare that the following is a full, clear, and reference being had to the accompanying drawings, which form part of this specification.

This invention is i'ng mechanism for oh cct is to regulate plied from the roll and duration of contact between the ductor roll and the fountain roll can bevaried, so be taken by the roll according to printing presses and its the amount of ink supducto'r from the fountain The. invention consists in"v.ery simple, ef-

ficient and novel means for accomplishing 'this object as hereinafter described. and a preferred .form "of mechanism embodying the invention is illustrated in the accompanying drawings in which:
