I, CHRISTOPHER CAIL, of 2, Kidwell's Park, Maidenhead; in the County
of Berks, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN PAPER-CUTTING MACHINERY, WHICH IMPROVEMENTS ARE, ALSO
APPLICABLE TO MACHINERY FOR RECEIVING PRINTED SHEETS FROM PRINTING
PRESSES," to be as follows:-
-
This Invention has for its object improvements in paper cutting
machinery, which improvements are also applicable to machinery for
receiving printed sheets from printing presses.
In machinery for cutting paper a continuous length of paper coming
direct from a paper making machine, or a length or lengths from a roll
or rolls of paper previously made, is or are conducted through the
cutting machine, and if the lengths of paper have to be divided length-
wise into two or more strips they are cut by circular knives, and

page_text: afterwards are divided into lengths by a straight knife called the breast
knife placed transversely across the machine. The sheets thus cut off
are conducted to an inclined receiving board or table and are made into
piles thereon by boys, and such piles of cut sheets have subsequently to
be counted out into quires or half quires.
In order to avoid this subsequent counting out of the piles of cut
sheets I mount the receiving board or table upon guides or wheels in
such a manner that it can be slid horizontally to and fro, and after the
requisite number of sheets for forming a quire or half quire have been
collected in each of the piles upon the table. I cause the table to be
shogged sidewise so that the succeeding sheets in place of being piled
directly over the sheets already upon it are placed so as to project beyond
them either to one side or the other, and when another set of cut sheets
sufficient to form a quiro or half quire has thus been collected the table
is shogged back again, and so on continuously.
The sheets of paper as they are collected upon the receiving table are
thus antomatically divided into quires or half quires, or it might be into
piles containing other desired number of sheets; suitable stops or guides
are provided to assist the boys to place the sheets correctly on to the
table.
In order thus to shog the receiving board or table at the required.
times a crank pin on the shaft from which the breast knife is actuated
may by a connecting rod give a to-and-fro motion to a lever carrying a
pawl, and this pawl may be caused to drive a ratchet wheel on a shaft
upon which are two discs carrying arms, and these as the shaft revolves
act alternately upon opposite ends of a lever so as to rock the lever first
in one direction and then-back again in the opposite direction, and by
interposed mechanism I cause the rocking of this lever to shift the
-receiving board or table to and fro..
Motion may also be transmitted from the shaft carrying the ratchet
wheel to a counting apparatus, so that the number of quires and reams

page_text: The receiving board or table upon which printed sheets coming from
printing machines are collected, may similarly be caused to shog to and
fro automatically, so that the sheets as they are collected are divided into
separate piles each containing any desired number of sheets; or the
receiving table may be formed of an endless band to which a step-by-
step motion always in the same direction may be automatically imparted.
