they are Delivered from a Printing Machine.
I, THOMAS CHADWICK, of Albert Street, Parsonage, Manchester, in the County
of Lancaster, Letterpress Printer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to apparatus for adjusting or laying evenly the sheets
of paper as they are delivered from the flyer of a printing machine and is designed
to provide apparatus which will permit of the raising of the flyer or taking off
board without any disconnecting or uncoupling of the parts.
It consists essentially in the combination and arrangement with the taking off
board of a printing machine of two reciprocating side gauges mounted on
reciprocating bar operated by a cam on the flyer rod which adjust the paper end-
wise and a reciprocating back gauge moving at right angles there-with fixed
stops or fences at one or both ends of the board and at one side thereof.
In carrying out the invention I provide a sliding bar or plate to move longi-
tudinally across the taking off board and a second sliding bar to move trans-
versely and at right angles thereto, one passing under the other. These bars
are connected by a bell-crank lever by which when the longitudinal bar is moved
the transverse bar is also moved. The bars are placed below the level of the
table and the bell crank lever is covered by a plate of sheet metal or other suit-
able material.
The longitudinal bar is placed so as to engage at one end with a wedge shaped
cam or its equivalent attached to the reciprocating flyer rod by which it is moved
in one direction, a spring moving it back. The one cam thus moves the two
rods backwards and forwards.
To the longitudinal rod are fitted two gauges one at or near either end which are
capable of adjustment to different sizes of sheets of paper. One of these gauges
only operates at a time, they being so arranged or disposed that they can be
At the right and
worked according to the side the machine is being fed from.
left ends of the taking off board are also fitted two adjustable stationary gauges.
To the transverse sliding bar is fitted a back gauge which moves to and fro
with the bar also capable of adjustment. This gauge is made with a number of
fingers or projecting pieces between which the fingers of the flyer fall without
striking the gauge.
There is no fastening or attachment to the flyer shaft or any part of the printing
machine other than the taking off board, hence the flyer or taking of board can
be raised or moved without any detaching or uncoupling of parts.

I, THOMAS CHADWICK, of Albert Street, Parsonage, Manchester, in the County
of Lancaster, Letterpress Printer, 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;
This invention relates to apparatus for adjusting or laying evenly the sheets
of paper as they are delivered from the flyer of a printing machine and is designed
to provide apparatus which will permit of the raising of the flyer or taking off
board without any disconnecting or uncoupling of the parts.
It consists essentially in the combination and arrangement with the taking off
board of a printing machine of two sliding reciprocating bars carrying side gauges
and a third sliding reciprocating bar at right angles thereto carrying a back
gauge the two side bars being connected together and to the back bar by two bell
crank levers pivoted to the board and operated together in one direction by a cam
on the flyer rod and in the opposite direction by a spring.
The invention will be fully described with reference to the accompanying draw-
ings:-
-
Fig. 1. Plan of the apparatus applied to the taking off board of a printing
machine.
Fig. 2. Sectional elevation on line - Fig. 1.
Fig. 3. Side elevation with the side gauges removed to show the actuating lever.
In the face of the taking off board A is formed a rectangular groove a running
across from side to side, and a second similar groove a¹ running centrally down
the board at right angles to the groove a.
Two reciprocating side bars B, C are placed to slide in the groove a and a
third reciprocating back bar D slides in the groove a at right angles to the
bars B and C. The grooves a, a¹ are of such a depth that the top of the sliding
bars B, C and D are level with the surface of the taking-off board A. Longi-
tudinal slots 13¹, C, D¹ are cut out of the bars B, C and D respectively to allow
of the side gauges b and c and the back gauge d being secured thereto by a bolt
and their positions being adjusted to different sizes of paper.
The side gauges care of any suitable construction and are attached to the
reciprocating bars B and C respectively by means of bolts b, c, passing through
the slots B1 (and secured above by wing nuts 62. By loosening the nuts 62
the position of the gauges bc on the bars B, C may be altered.
The back gauge is preferably in the form of a bar of wood or metal at right
angles to the sliding bar I), having a number of fingers or projections between
which the fingers of the flyer fall without striking the gauge, and is attached to
the reciprocating bar D by means of the bolt and wing nut . Projections
at the ends of the gauge slide in V shaped grooves in the taking off board A.
At the edge of the taking-off board opposite to the back gauge is a fixed fence
or stop E against which the back gauge pushes the sheets of paper.
To the table are pivoted two bell crank levers K and K¹ pivoted on the pins kk
One end of the lever K engages a pin on the side bar B and one end of the lever K
a pin on the end of the side bar C and the free ends of both these levers engage
a pin on the end of the back bar D thereby connecting the three sliding bars so
that they all move at the same time.
Above one outer end of the reciprocating side bar B and at right angles thereto
is a shaft F fitted to the taking off board A by means of the journals G in which

page_text: it oscillates. To one end of the shaft F is fixed an arm or lever F¹ carrying a
runner f which works against the wedge-shaped cam H on the flyer rod H' and on
the shaft F immediately above the sliding bar B is fixed a lever F preferably
opposite to the arm F engaging a pin ffixed to the bar B.
The sliding bar B is thus moved in one direction by the cam H, a spring moving
it back, so that the bar B is given a reciprocating motion.
The motion of the bar B is communicated to the bars C and D by means of
the bell-crank levers K, K¹, pivoted at k k to a metal plate M sunk in the taking-
off board A. Both levers K and K' are below the sliding bars B, C and D. The
bell crank levers are covered by a metal plate not shown in the drawings.
A spring S attached to the sliding bar D at s and to the metal plate M at s¹
moves back the sliding bars D, B and C when they have been moved forward by
the cam H thus giving a reciprocating motion to the bars.
Preferably one of these gauges only operates at a time, they being so arranged
or disposed that they can be worked according to the side the machine is being
fed from. At the right and left ends of the taking-off board are also fitted two
adjustable stationary gauges or fences N.
In operation after each sheet of paper has been deposited on the taking-off board
by the Hyer the cam H on the flyer rod H moves the three bars B, C and D
and the three gauges b c and d inwards, thus placing the sheet evenly on the
pile, as the flyer is coming down again on the taking-off board, the spring S
moves the gauges outwards ready to receive the next sheet of paper.
There is no fastening or attachment to the flyer shaft or any part of the print-
ing machine other than the taking-off board, hence the flyer or taking-off board
can be raised or moved without any detaching or uncoupling of parts.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I claim
is:-
1. The combination with the taking-off board of a printing machine of
apparatus for laying the sheets of paper evenly in a pile comprising two reciprocat-
ing side bars carrying gauges and a reciprocating back bar at right angles thereto
carrying a back gauge connected together at their inner ends by bell crank
levers to as to move together operated by cam on the flyer rod in one direction
and by a spring in the opposite direction and one or more stops or fences against
which the gauges may push the sheets of paper substantially as described.
2. The combination with the taking off board of a printing machine of apparatus
for laying the sheets of paper evenly in a pile, having the several parts con-
structed and arranged substantially as and for the purpose described and shown in
the accompanying drawings.
