Improvements in Rotary Printing Machines.
I, JULES MICHAUD, of 96, Rue d'Assas, Paris, France, Engineer, 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:-
-
The improvements forming the object of the present application for Patent consist
in a particular arrangement of the printing cylinders of rotary printing machines for
enabling the fixing on such cylinders in the parts which correspond to the margins
of the printed sheets, of printing plates, clichés or characters for printing in such
margins. This invention is more particularly applicable for printing the latest
news in journals in the margins thereof.
In the accompanying drawing
Fig. 1 is a side elevation of a printing cylinder on the left hand side of
which is shown a clamp for a cliché of latest news, at the place occupied by the
rule which ordinarily determines the blank or margin of the journal. On the right
hand side is shown, fixed on the cylinder, a box also occupying the place of the
rule which determines the blank and containing a form made of movable
characters.
Fig. 2 is a cross section of the cylinder with the cliché clamped thereto.
Fig. 3 is another Cross section of this cylinder with the box of movable
characters.
Fig. 4 on the left hand side shows a section of the supplementary cliché with its
clamps, and on the right the section and the mode of clamping the box containing
the movable characters.
The printing cylinder Fig. 1 on the left hand carries two clichés 1 and 2 clamped
in the ordinary manner employed by bearing against a fixed circle 3 and forced by
two clamps or portions of circles 4 and 5. In the space left empty between these
two clichés a clamp 6 moves, this clamp first serving to determine the position of
the two clichés 1 and 2 between which it is to pass. When the cliché 1 is ready
it is placed on the evlinder and is held there by the clamp 6 forcing it against
the fixed circle 3; the clamp is actuated by a screw 8 which is turned by
means of the square end 9 and which is mounted in a part 10 secured to the
cylinder.
When the latest news is to be composed in movable characters and not as a
cliché, I construct the cylinder as indicated on the right hand side of Fig. 1.
The characters 11 are contained in a box 12 which is placed in a recess formed
in the cylinder; the bottom of the box 12 is made in the form of an are of a
circle so that the letters will be arranged in the circle formed by the exterior of
the clichés 1 and 2; the letters are held in the box by means of a rule 13 against
which acts a screw 14.
The two extremities of the box 12 are inclined as will be seen in Fig. 4 so that
when once placed on the cylinder and pressed upon by the movable circle 15 which
is actuated by means of the nut 16, it cannot escape.
I may of course construct the cylinders either to receive supplementary clichés,
or to receive matter formed of movable characters.

page_text: 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-
In rotary printing machines
1. The combination with the printing cylinders of clamps permitting of the fixing
of printing plates er clichés in the parts left ordinarily empty and corresponding
to the margins or blanks of the printed sheets.
2. The combination with the printing cylinders of boxes containing matter
formed of movable characters and of means employed for fixing these boxes on
the printing cylinders in the parts which correspond to the margins or blanks of
the printed sheets.
3. The employment of the two arrangements described either separately or in
combination.
4. The combination of the printing plates or clichés and of clamps serving to
secure the necessary space between the printing plates or clichés.
