Hick at the Office of the Commissioners of Patents, with their Petition,

We, JAMES SALMON, of Manchester, in the County of Lancaster, Engineer,
and GEORGE WILLIAM HICK, of Leeds, in the County of York, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINES FOR RULING PAPER, PART OF WHICH IMPROVEMENTS IS ALSO APPLICABLE TO
GUIDING PAPER INTO PRINTING AND OTHER MACHINES," to be as follows:-
In the first place our improvements consist in arranging the machine in such
a manner that the paper may be ruled on both sides, although it is passed
only once through the machine, and we prefer to adopt the following method
of putting this part of our Invention into practice:-We use a machine
having a series of endless aprons passing over rollers. The machine is
furnished with two rows of pens, and the paper on being fed into the
machine passes under on of these rows of pens and is then passed along the
aprons or travelling sheets, which should be of sufficient length to allow the
lines to dry, and these aprons are so arranged that when the paper arrives
at a certain point in the machine it is turned over and carried under the
second row of pens, and thus ruled on the other side, after which it
passes
out of the machine. The paper is held down on to he aprons by bands
which pass over grooved rollers.

to raise the pens after the paper has passed from underneath them in order
to prevent them from inking the aprons. One mode of accomplishing this is
by means of a rod and an adjustable tappet connected to a crank on a revolving
shaft. The rod works through a swivel eye on a lever arm; this lever arm
when perfectly free raises the pens off the aprons by its own weight, but
when pressed back by means of the adjustable tappet on the rod it allows the
pens to fall and to press lightly upon the paper to be ruled.
In the next place our improvements consist in a novel arrangement for
guiding the paper into the machine. For this purpose we use a roller which
has a feather or projection running along its whole length; this roller is loaded
in such a manner that this feather shall be brought up into a certain definite
position whenever the roller is free to move; close to this roller a segment
roller revolves, the centres being sufficiently near one another that the segment
may press upon the roller. This apparatus is placed close to the feed board
of the machine, and its action as is follows:-A sheet of paper being pushed
forward comes in contact with the feather or projection on the roller and
thus adjusts itself to the proper position, the revolving segment then comes
upon it and carries it forward, the edge of the segment pushing the projection
on the roller out of the way as soon as the segment and paper has passed;
the roller being loaded immediately returns to its former position to be ready
for another sheet. This form of guide may also be applied to printing and
other machines.
