ROVISIONAL SITUT
Improved Means for Adjusting Sheets as they are Delivered from
Printing Machines.
I, WILLIAM HENRY CLEGG of 135, Brunshaw Road, Burnley, in the County
of Lancaster, Mechanic, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved sheet adjuster for printing machines,
whereby the printed sheets of paper, after leaving the flyer, fall on to the table of
the machine and are automatically adjusted.
In carrying my invention into effect, I fit to the table of the machine, an
additional board or platform, and in this platform I form four grooves, running at
right angles to each other. The four adjusting plates, which are for keeping the
sheets of paper in order, are provided with small sliding brackets or holders, by
which they are adjustably secured by a set screw to four bars placed within the
aforesaid grooves diverging at right angles to each other.
Two of the said bars, which carry the adjusting plates are movable, and
mounted to be capable of sliding within the grooves, while the remaining two are
stationary.
One of the said movable or sliding bars has a pin or stud, which works in a
radial slot in a cam plate, in such a manner, that when the cam plate is recipro-
cated, it transmits a to and fro movement to the movable bar and consequently to
the sheet adjusting plate fixed to it. The movable bar carrying the adjacent
sheet adjusting plate is likewise moved to and fro by being connected to the
cam-plate by a lever or link pivoted at its centre. The cam-plate may be
reciprocated by an eccentric or crank from any convenient source, but preferably
from the flyer shaft of the printing machine.
In this way the two adjacent sides or adjusting plates are moved backwards and
forwards by the cam-plate, and continually push the sheets of paper as they leave
the fiyer and fall on the table against the stationary adjusting plates, whereby the
sheets of paper are kept in even layers.

Printing Machines.
I, WILLIAM HENRY CLEGG of 135, Brunshaw Road, Burnley, in the County
of Lancaster, Mechanic, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to an improved sheet adjuster for printing machines,
whereby the printed sheets of paper after leaving the flyer, fall on to the tabl
of the machine and are automatically adjusted.
In carrying my invention into effect I fit to the table of the machine, an
additional board or platform, and in this platform I form four grooves, running at
right angles to each other.
The four adjusting plates, which are for keeping the sheets of paper in order,
are provided with small sliding brackets or holders, by which they are adjustably
secured by a thumb screw to four bars placed within the aforesaid grooves
diverging at right angles to each other. Two of the said bars, which carry the
adjusting plates are movable and mounted to be capable of sliding within the
grooves, while the remaining two are stationary.
One of the said movable or sliding bars has a pin or stud which works in a
radial slot in a cam plate, in such a manner that when the cam plate is recipro-
rated it transmits a to and fro movement to the movable bar, and consequently to
the sheet-adjusting plate fixed to it. The movable bar carrying the adjacent
sheet adjusting plate is likewise moved to and fro by being connected to the
cam-plate by a lever or link pivotted at its centre. The cam-plate may be
reciprocated by an eccentric or crank from any convenient source, but preferably
from the flyer shaft of the printing machine.
In this way the two adjacent sides or adjusting plates are moved backwards and
forwards by the cam-plate, and continually push the sheets of paper as they leave
the flyer and fall on to the table against the stationary adjusting plates, whereby
the sheets of paper are kept in even layers.
My invention will be fully understood by reference to the accompanying sheet
of drawings, in which A is the table of the printing machine, having the additional
board or platform B, B, B, B, which may have four grooves C, C, C, C,
formed in it running at right angles to each other, or there may be four separate
boards, of such size and dimensions, and placed at such distance apart as to leave
the said grooves running between them. To keep the sheets of paper in order
and to adjust them as they fall from the flyer D) of the printing machine, I employ
four adjusting plates E. F. G. H. These adjusting plates are secured by clips J
or the like to four small sliding brackets or holders K, which slide on three bars
or guide rods L. M. N and are adjustable upon the same by thumb screws not
shewn, and fixed to clips J by thumb screws P, or any other means of fastening
may be adopted. The said guide rods or bars L. M. N. are placed within the
grooves formed in the additional board mounted on the table of the machine, and
two of them L. M. are fixed stationary. It will be noticed that the fourth guide
rod described in my Provisional Specification is dispensed with, the guide rod M
extending across both grooves. The rod N is movable, but it will be noticed that
instead of the bracket O. carrying movable adjusting plates H being adjustably
fixed to the guide rod M the said bracket O. is arranged to slide on guide rod M
through the medium of link V in the manner hereinafter described. Or the guide
rod M may be shortened and an additional and movable guide rod employed
arranged to slide similar to the movable rod N.

page_text: The two adjusting plates G H, are intended to push the sheets of paper as they
fall from the flyer D and adjust them by knocking them against the stationary
plates. This is effected by mounting the bar N and the bracket O so as to be
capable of sliding within the grooves, whilst the remaining two are stationary as
before stated.
The said movable or sliding bar N has a pin or stud (not shewn on the
drawings) which slides in the radial or similar slot Q shewn in dotted lines on the
underside of cam-plate R, which slides on the slide rest X.
The cam-plate carries a small bracket R', formed with a recess, into which
drops stud $ of connecting rod T operated by crank U preferably from the flyer
shaft of the machine, but it may be actuated from any other convenient source.
The other movable or sliding bar N is actuated by link V centred at VI, and
connected at its other extremity to rod W, which receives the reciprocating
movement of the cam plate.
By the simple and novel arrangement of mechanism described, the, to and fro
movement of the crank has not only the effect of so imparting motion to the cam
plate R that it will move the adjusting plates G H so as to knock the sheets of
paper in position, but it will be observed that the plate G (by its being operated
through the medium of sliding bar N, which receives its motion by the stud
working in the radial or V groove of the cam plate It) has the effect of giving a
second or extra jog to the sheets of 'paper for every single knock given by the
adjusting plate H.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I am aware that pushers
for evening-up sheets as they are delivered from printing machines have previously
been operated by links connected to arms on the flyer shaft, and I make no general
claim to such construction, but I declare that what I claim is:-
1. The improved arrangement and combination of mechanism for adjusting the
sheets of paper as they leave the flyer of the printing machine, substantially as
described and illustrated.
2. The cam plate R formed with slot Q, into which slides the stud of the sliding
bar N, carrying adjusting plate G, for giving a second or extra knock to the
sheets of paper as they leave the flyer D, also the combination of the same with
the rod W, and link V for transmitting motion to the sliding bracket 0 or the
ike carrying adjusting plate H, substantially as and for the purpose specified.
2. Operating both adjusting plates GH from connecting rod T or like
mechanical equivalent, substantially as described and set forth.
