page_text: We, SETH SAVILE, of 11 Weston Road, Ilkley, in the county of York, Printer's
Machinist, and PERCY LUND, of Eldermere, in Ilkley aforesaid, Printer and
Publisher do hereby declare the nature of the said invention for "AN IMPROVED
TAKING OFF APPARATUS FOR SINGLE CYLINDER PRINTING MACHINES" to be as
follows:-
Our invention relates to an improved flyer for single cylinder letter press
printing machines by means of which the machine can be conveniently manage 1
by one operator as by our improvements the printed sheets on leaving the cylinder
are conveyed over and deposited with the printed side upwards on the back table
of the machine.
To carry out our invention we fix on the side frames of the machine two
standards or uprights, one at each end of the cylinder and connected together at
the top by a cross stay from which cross stay is suspended a frame the full width
of and reaching down to the front of the cylinder. The bottom of the frame is
retained at the requisite distance from the cylinder by means of clips or catches
fixed to the standards and clasping the sides of the frame.
A light shaft is fitted across the bottom of the frame which shaft has a rocking
motion imparted to it by means of a cam fitted on the cylinder brake wheel
coming in contact with a lever placed on the end of such shaft. Near the ends of
the light shaft two short levers are fixed which levers bear against and actuate a
flat rod working in horizontal slots immediately above the light shaft. The flat
rod is thereby pressed towards the cylinder at each revolution of the cam on the
cylinder brake wheel. Suitable springs are fitted to the frame which springs
cause the flat rod and light shaft to recover their original position after being
actuated by the cam.
A long slot or slots is or are formed in the flat rod to which slot or slots are
fitted by means of adjustable screws a number of strips of curved steel or fingers
pointing towards the cylinder.
When a sheet is on the point of being released by the grippers on the cylinder
the cam on the brake wheel actuates the lever on the light shaft fitted across the
frame and the light shaft, by means of the short levers, presses the flat rod carrying

page_text: the fingers towards the cylinder which fingers guide the released sheet up between
suitable rollers and tapes fitted to the frame. The sheet is conveyed by the rollers
and tapes over the cylinder on to an ordinary wooden fyer which deposits the
sheet with its printed side upwards on the back table of the machine.
The rollers and tapes are driven from a small pulley placed on the main shaft.
When it is necessary to make ready a "fresh form" the clips or catches on the
standards clasping the sides of the frame are opened and the frame and apparatus
is swung over clear of the cylinder and placed at rest on projections springing from

COMPLETE SPECIFICATION.
An Improved Taking Off Apparatus for Single Cylinder Printing
Machines.
We SETH SAVILE, of 11 Weston Road, Ilkley, in the county of York, Printer's
Machinist and PERCY LUND, of Eldermere in Ilkley aforesaid Printer and
Publisher, do hereby declare the nature of the said invention for "AN IMPROVED
TAKING OFF APPARATUS FOR SINGLE CYLINDER PRINTING MACHINES" and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
'
Our invention relates to an improved flyer for single cylinder letter press
printing machines by means of which the machine can be conveniently managed
by one operator, as by our improvements the printed sheets on leaving the cylinder
are conveyed over and deposited with the printed side upwards on the back table
of the machine.
To carry out our invention we fix on the side frames of the machine two
standards or uprights one at each end of the cylinder, and connected together at
the top by a cross stay, from which cross stay is suspended a frame the full width
of and reaching down to the front of the cylinder. The bottom of the frame is
retained at the requisite distance from the cylinder by means of clips or catches
fixed to the standards and clasping the sides of the frame.
A light shaft is fitted across the bottom of the frame which shaft has a rocking
'motion imparted to it by means of a cam fitted on the cylinder brake wheel
coming in contact with a lever placed on the end of such shaft. Near the ends of
the light shaft two short levers are fixed, which levers bear against and actuate a
flat rod working in horizontal slots immediately above the light shaft. The flat

page_text: rod is thereby pressed towards the cylinder at each revolution of the cam on the
cylinder brake wheel-Suitable springs are fitted to the frame which springs cause
the flat rod and light shaft to recover their original position after being actuated
by the cam.
A long slot or slots is or are formed in the flat rod to which slot or slots are
fitted by means of adjustable screws a number of strips of curved steel or fingers
pointing towards the cylinder.
When a sheet is on the point of being released by the grippers on the cylinder,
the cam on the brake wheel actuates the lever on the light shaft fitted across the
frame, and the light shaft by means of the short levers, presses the flat rod
carrying the fingers towards the cylinder, which fingers guide the released sheet up
between suitable rollers and tapes fitted to the frame. The sheet is conveyed by
the rollers and tapes over the cylinder on to an ordinary wooden flyer which
deposits the sheet with its printed side upwards on the back table of the machine.
The rollers and tapes are driven from a small pulley placed on the main shaft.
When it is necessary to make ready a "fresh form" the clips or catches on the
standards clasping the sides of the frame are opened and the frame and apparatus
is swung over clear of the cylinder and placed at rest on projections springing
from the top of the frame.
In order to enable my invention to be fully understood I will proceed to
describe the same by reference to the accompanying drawing in which figure 1
represents a side elevation of the end of a single cylinder printing machine with
my improvements applied thereto; figure 2, represents a back elevation of the
same; figure 3, is an elevation showing the printing cylinder and taking off rollers
in section; figure 4, is an elevation partly in section showing the moveable frame-
work upon which my improved taking off motion is carried; figure 5, is a side
elevation of one of the pillars to which the framework is attached and which
serves to steady it when in operation, and figure 6 is a front elevation of one of
the sockets in which the pillars are fixed; figure 7, is a plan of the flat rod holding
the springs or fingers for taking off the sheet of paper from the cylinder and
guiding it to the taking off roller.
The standards upon which the printing cylinder and the taking off apparatus
are supported are represented at A and the printing cylinder at B; the latter is
carried by a shaft working in bearings fitted in vertical slots in the standards A,
The fly wheel C is controlled by a brake D acting upon its under side, and upon
one side of this wheel is fixed a cam or tappet E, for the purpose of actuating the
lever F, upon the end of which is the friction roller G.
When the printing cylinder B, and fly wheel C, make a revolution, the cam or
tappet E, comes in contact with, and presses back the friction roller G, attached to
the lever F, which lever is fixed on the end of the shaft H, which passes from side
to side across the machine, and is supported at each end in bearings in the movable
frame J. Near each end of the shaft H, levers K are fixed at, or nearly at, a right
angle to the lever F, and across from side to side of the machine; between and
attached to these two levers is a flat rod L, the ends of which pass through slots in
the moveable frame J. Upon the flat rod L, several fingers or flat springs M are
fixed, which point in the direction of the cylinder B, and each time the lever F, is
actuated by the cam or tappet these fingers are pressed close to the surface of the
cylinder and pass under the edge of the paper which is upon the cylinder, whereby
the paper is turned up and passes over the upper surface of the fingers M, and is
carried by tapes or strings partly round the cylinder N, whence it is discharged in
the direction shown by the arrows, and is caught by an ordinary flyer, and
deposited, with its printed side uppermost, upon the ordinary taking off board of
the machine or upon a board placed higher than the feeding board and in full view
of the operator.
The taking-off roller N, has grooves O, formed therein to admit the ends of the
laths of the flyer which can rest therein. After the fingers have been actuated by
the cam and have guided a sheet of paper on to the tapes, by which the sheet is

page_text: carried to the taking off roller, the rod L, carrying the fingers is pressed back into
its original position, and the fingers are removed from contact with the printing
cylinder B, by means of the springs P. The driving roller Q, is driven by a pulley
for the purpose of actuating the tapes which convey the printed paper to the
taking off roller N and these tapes also pass over, and are guided by the
rollers R.
The strong pillars T, are fixed in sockets U, attached to the standards A, the
said pillars serving to hold the moveable framework J, firmly in position when the
taking off apparatus is in operation; the pillars T, are connected with the frame-
work by short shafts V, which fit into holes in the framework and also into holes
in the heads of the pillars T, where they are held securely in position by means of
the set screws W.
The sockets U, are made with a sliding cover so that when it is desired to
disconnect the taking off apparatus, the pillars T; can be withdrawn from the
sockets (which are loosened for the purpose) and the whole framework can be
lifted over out of the way; until it rests in the position shown in dotted lines in
figure 4. .
The moveable framework J receives support also from the two ends of the shaft
which carries the driving roller Q, upon which shaft the framework can swing
hingewise when released from the standards A.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1. The construction and use of a taking off apparatus applied to single cylinder
printing machines operating substantially in the manner described for the purpose
of returning the printed sheet of paper to the operator at the table of the printing
machine or to the ordinary taking off board of such machine.
2. The construction and use of fingers or flat springs attached to a flat rod and
actuated in the manner described for the purpose of taking off the sheets of paper
from the cylinder of a printing machine and returning them to the operator
substantially as hereinbefore described and represented in the accompanying
drawing.
3. The combination of a cam upon the brake wheel with the fingers or flat
springs and taking off rollers and tapes substantially as and for the purpose herein
Bet forth.
