London S.E., Publishers' Clerk, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
An improved rotary colour printing machine for printing any number of colours
at one operation.
Consisting of a series of cylinders radiating from a centre as set forth in the
accompanying diagram representing an eight colour machine viz. :—
(A.) Printing cylinders about one half of the circumference of which, form
inking tables and the other half, beds on which are fastened suitable curved
plates from which the impressions are to be made.
These cylinders are driven by a central cog wheel revolving on the axle C.
B. Pressure cylinders revolving by friction with the printing cylinders over
which the paper travels, guided by tapes, receiving as it passes between the cylinders,
an impression from the plates on each of the cylinders A in rotation.
C. The driving axle.
D. Ink ducts, with troughs T.
I Inking and distributing rollers

page_text: 1. Ink trougns.
E. Feeding table from which the paper passes into the machine.
G. Delivery table on which the finished pictures are received.
H. Tapes.
Each printing cylinder is capable of adjustment for exact registration, and the
inking rollers can all be readily removed to allow for cleaning and room for fixing
the plates on the bed of the printing rollers.
The paper may be supplied either from a roll in a continuous web, or in separate
sheets.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
A Patent for the particular arrangements of the various parts of the machine as
here described, and set forth.
Dated this Eighth day of December 1891.
