Improvements in the Mounting of the Taking off Apparatus of
Printing Machines.
We THOMAS FURNIVAL of the Reddish Ironworks Reddish in the County of
Lancaster Engineer, EDWARD TUDOR Junior of the Reddish Ironworks Reddish in
the County of Lancaster, Cashier, CHRISTOPHER PRESTON of Devonport Green
Wilmslow in the County of Chester, Gentleman and WILLIAM BYWAY of 138 Princess
Street Manchester in the County of Lancaster Plumber do hereby declare the naturo
of this Invention and in what manner the same is to be performed to be parti-
cularly described and ascertained in and by the following statement and accompanying
drawings

--
Our Invention relates to the printing machines which are provided with impression
cylinders which receive and hold the paper and by their revolving or vibrating move-
ments bring the paper into printing contact with the form of type or with the stereo
plate or other printing medium and particularly to the cases wherein so termed
flyers" or taking off apparatus are employed to automatically remove or discharge
the printed sheet as in the machines commonly known as "Wharfedale" Machines.
At certain times it is necessary to obtain ready access to the impression cylinder as for
example when making ready" that is to say when adapting the surface of the cylinder
to the particular requirements of the work to be done as is well understood and at
such times the "taking off" apparatus is in the way. Previously to our Invention
the said apparatus has been mounted in a so termed flyer frame which has been hinged
so that one end could be raised thereby giving access to the impression cylinder from
one end of the machine but when it has been desirable to obtain access to the cylinder
from the other end of the machine it has been necessary to dismount certain parts of
the apparatus. In our Invention we mount the flyer frame on two sets of bearings so
arranged and adapted as that either set can become a fulcrum of movement of the
flyer frame. In order that our invention may be fully understood we will describe
the same with reference to the accompanying drawings wherein Fig. 1 represents a
side elevation of so much of a printing machine as is necessary to the illustration
of our invention. Figs. 2 and 3 representing the same parts but having the flyer
frame in different positions. In the said Figs. A is the impression cylinder B is

page_text: the flyer frame and c is the taking off cylinder which is mounted on and carried
by the said frame. As the clips and tapes are or may be formed and arranged in
the ordinary manner they are not included in the drawings. The flyer frame B
is provided with two sets of pivots d d' which rest in bearings or seatings e e¹ formed
in the fixed side piece f which forms part of the framing of the machine or is
secured thereto. It will be understood that there is a corresponding side piece
provided with corresponding bearings at the other side of the machine so that the
flyer frame rests in four bearings and that the pivots on the other side of the flyer
frame are exactly in line with those which appear in the drawings.
The
bearings e el are open at the top and are shaped so that either set of pivots can be
lifted out of the bearings the other set remaining in their bearings. In the example
the said bearings are provided with hinged caps g g₁ which when brought down over
the pivots and secured keep the same from rising out of the bearings. An enlarged
view of the bearing e' with its cap appears at Fig. 4. The said caps may be secured
by any suitable means. In the example a hole in the free end of the cap, co-incides
with a hole in the part so that when a pin is passed through the holes the cap is
firmly secured. Figs. 2 and 3 illustrate the two positions into which the flyer frame
can be turned. In the case of Fig. 2 the caps represented by gliave been unfastened
and turned over so as to release the swing frame which has then been raised by one
end the pivots forming the fulcrum of movement. The frame is fastened in its
elevated position by means of a prop or strut i or of two such props one on each side
of the machine. The said prop is hinged at k and is formed with a slot or notch
which when the flyer frame is raised into either of its two positions engages with a
stud or pin and thereby sustains the frame, a spring m tending to keep the prop
engaged with the stud. In the case of Fig. 3 the caps y have been unfastened and
turned over and the flyer frame has been turned upon the pivots d as will be clearly
seen the apparatus being placed in this position when it is not required to be used
during the printing operation. It will be apparent that the flyer frame with its
apparatus may be lifted into either position with similar readiness so that access can
be had to the impression cylinder from either end of the machine.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
(1.) In a printing machine of the class herein referred to mounting the frame
which carries the automatic taking off apparatus upon two sets of pivots in such a
manner as that the said frame may be turned upon either set in order to give access
to the impression cylinder from either end of the machine or side of the cylinder as
may be required substantially as set forth and indicated.
(2.) In a printing machine of the class herein referred to, the flyer frame, provided
with two sets of pivots d and d mounted in two sets of bearings or seatings e, e¹
which are provided with hinged or removable caps in order that either set of bearings
may be used as a fulerum of movement for the said flyer frame substantially as and
for the purpose set forth and indicated.
