Year: 1873

page_text: LETTERS PATENT to the Louis Simon, of Wilford Road Works,
Nottingham, for the Invention of "IMPROVEMENTS IN ROTARY PRINTING
MACHINES."-A communication from abroad by the Bullock Printing
Machine Company of Philadelphia.
PROVISIONAL SPECIFICATION left by the said Louis Simon at the
Office of the Commissioners of Patents, with his Petition, on the
15th March 1873.
I, LOUIS SIMON, of Wilford Road Works, Nottingham, do hereby
3 declare the nature of the said Invention for "IMPROVEMENTS IN ROTARY
PRINTING MACHINES," (a communication to me from abroad by the
Bullock Printing Machine Company of Philadelphia) to be as follows:-
This Invention consists of improvements in or additions to the machine

page_text: known as the Bullock Printing Machine, and for which former Letters
Patent were granted dated the 15th day of June 1869, No. 1831.
The Bullock Printing Machine prints from a roll of paper by cutting
the sheets before or after printing by means of cutting cylinders, in con-
sequence of which the size of the paper depends upon the size of cutting
cylinders.
sequence of which the size of the paper depends upon the size of cutting
cylinders.
My improvements are,―
Firstly. That I print loose sheets also on both sides, or perfect, which
are laid on one feeding board by one feeder, or I can use 2 feeding
boards, or more if necessary, by which means I can print on every size of
paper to a certain limit.
Secondly. In order to avoid the setting-off of the ink on the side
printed first, and to obtain a better quality of printing, I use impression
cylinders which are double or three or four times the size in diameter
and circumference than the printing cylinders, which I call a multiple
impression cylinder, and I may use one or two of such multiple
cylinders.
Thirdly. An arrangement for regulating and facilitating the feeding
of the sheets in a more effective manner, also in the delivery of the
sheets at once from the last impression cylinder without additional
cylinder or tapes. These improvements are accomplished by raising and
lowering the feed boards alternately, the sheet being pushed against fixed
stops or plates above the feed boards, and then the feed boards sinking
below these stops or plates allow the grippers to lay hold of the sheets.
And the delivery is improved so far as to ensure the sheets as they move
down against the delivery belts being kept in close contact with the
second impression cylinder until arriving at the gripper belts. And this
is done by means of a revolving cylinder or brush placed so as to press
the sheet against the second impression cylinder, and thus prevent it
from flying off, which it is occasionally liable to do.
Fourthly. An improved arrangement of the various rods in the rollers
in the cylinders for fastening the blankets and calico sheets. This
consists in allowing the blankets and calico sheets to be removed and
replaced as speedily as possible, and is effected by means of a number of
hooks fixed on the interior surface of the first and second impression
cylinders, and flat loose bars with square holes corresponding with the

page_text: hooks being stitched on to the blankets and sheets and hooked altogether
on to the hooks, thus greatly facilitating the getting on and off of the
various blankets and sheets.
Fifthly. In the combination of the various type impression and inking
cylinders, which consists in having the feed cylinder at the top and the
first and second impression cylinders alternately below in a slanting
direction, and the two type and inking cylinders in front and at the back
of the machine and clear and out of the way of the printing cylinders.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said Louis
Simon in the Great Seal Patent Office on the 11th October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOUIS

that I, the said Louis Simon, my executors, or administrators, by an
instrument in writing under my, or their, or one of their hands and
