It will be composed of :-
1º One typo cylinder and its inking rollers.
2º One special blanket cylinder if impossible to use one of the blanket cylinders
of the machine to which this addition will be brought.
8° One frame supporting the type-cylinder, inking rollers, and blanket-cylinders,
(if any); this frame affixed either wholly to the principal frame, or in part to it,
in part to the ground.
So by these transformations and additions, two impressions may be taken by
each side of paper, if the new type-cylinders are disposed for working upon the
recto and verso of the sheet. Let now each of the type-cylinders, working upon
the same side of the paper, be inked with a different colour and the polychromatic
impression will be obtained, and used not only for cues and advertisements but
in any way intended.
More than one auxiliary apparatus may be used and combined together in such
a manner as to obtain several impressions upon each side of the sheet.
The transformation of cutting rollers above described may be applicated to the
carrier and folding rollers; for that purpose, the first of two opposite carrier rollers
will be coated with a blanket, and so becomes an impression-cylinder. The second
roller will be disposed for receiving types: either moveable, or stereo-plates. The
surface of these types being supplied with a set of inking rollers. The paper
travelling between the two carrier-rollers so transformed will take one impression.
In the same fashion, a pair of opposite folding rollers may be transformed: one
being coated with a blanket, and the second having its surface disposed for
receiving types.

Impression.
I GABRIEL ARNAUD BÉDART doctor of medicine, of La Rochelle 8 rue des
Fonderies departement de la Charente Infèrieure in France do hereby declare the
nature of my invention for IMPROVEMENTS IN ROTARY PRINTING MACHINES FOR
POLYCHROMATIO IMPRESSION, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
My invention relates to the construction and arrangement of certain parts of
the rotary printing machines, in such a manner as to print in several colours the
different parts of newspapers, namely: advertisements, cues; or the different parts
of any publication printed with such machines.
Actually the newspapers are printed with the same colour, and then in order to
attract readers' attention among the other advertisements many very ingenious
means are used by the advertisers They employ letters of a large size, or the
repetition of the same word. Let the words forming one advertisement be printed
in red colour among the other advertisements printed with black ink, these red
words will no doubt attract readers' sight and consequently attention.
For that purpose I transform the cutting rollers of web rotary printing machines,
into a complete printing apparatus.
One of the cutting rollers, the one bearing the knife or perforator is coated with
a blanket and so becomes an impression-cylinder; the second cutting-roller has its
surface disposed for receiving moveable type or stereoplate. The type when
affixed to its surface shall keep uncovered the longitudinal cleft into which the.
knife or perforator works. The new type-cylinder will be supplied with a set of
inking rollers.
So, the printed sheet when passing between the transformed cutting rollers, will
be cut and will take a second impression. Let the two type-cylinders working
upon the same side of the sheet, be inked with inks of different colours, a poly-
chromatic printing will be obtained.
Having thus described the nature of my invention and in what manner the same
is to be performed I claim in respect of rotary web printing machines
The transformation of cutting rollers in such a manner that they cut and print
together, for the purpose of having a new type-cylinder printing upon the same
side of the sheet, yet printed before being cut, or having to be printed after having
been cut, as in a few rotary machines.
In witness thereof, I, the said Gabriel Arnaud Bédart have hereunto set my
hand this eight day of December eighteen hundred and eighty five.
