Improvements in the Delivery Apparatus of Printing Machines.
I, JOHN KELLEY, of Albion Works, Otley, in the County of York, Printers' Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in the method of and apparatus for
mounting, lifting and connecting the cylindrical flyer apparatus of printing machines,
and arranging the parts in such a manner as to give greater facilities of access to the
type and cylinder than hitherto.

In carrying out my invention, instead of the usual framework, I fix on cach
cylinder stand, a perpendicular pillar of small diameter or section, in such a position
The two sido
as to cause no obstruction to the operator when "making ready.'
pieces which contain the flyer apparatus are prepared with long bosses which embrace
the pillars and effectually guide the apparatus when moved up and down.
Across the top of the pillars 1 mount in suitable bearings a shaft, on which is fixed
a hand wheel, and two pullies of equal size, and a third pulley by preference somewhat
larger in diameter. To the peripheries of the first named pullies are attached chains
or the like, the opposite ends of which are connected to the flyer apparatus, and to the
periphery of the other pulley is attached a chain and weight which acting in con-
junction with the other pullies on the wheel and axle principle, facilitate the lifting of
the flyer.
By means of the hand wheel, the shaft is turned on its axis, and the flyer apparatus
lifted to the desired position, where it is retained by a pawl and catch provided for the
purpose.
In the class of printing machines known as "Wharfedale" the cam bar which gives
motion to the flyer has been located under or in close proximity to the flyer shaft, in
which position it has been found in practice to be a great obstruction to the operator
when working at the forme on the machine.
This part of my invention consists in locating and arranging the cam bar in such
position that it is away from the flyer and out of the way of the operator, which is
accomplished by means of an intermediate bar of suitable length with a toothed rack
attached thereto in such position as to gear with a toothed wheel on the flyer shaft.
The intermediate bar may be placed in a horizontal or inclined position supported by
rollers or other suitable bearings on which is free to move backwards and forwards,
and to be lifted at the opposite end to that of the rack.
The free end of the said bar is so arranged as to be automatically engaged with and
disengaged from the cam bar, and when in operation, the cam bar imparts motion to
the flyer through the intermediate bar; and when the flyer is lifted, the type table
and cylinder are free from the obstructions caused by the flyer apparatus when
mounted and arranged in the usual manner.

COMPLETE SPECIFICATION.
Improvements in the Delivery Apparatus of Printing Machines.
I, JOHN KELLEY, of Albion Works, Otley, in the County of York, Printers' Engineer,
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 certain improvements in the method of and apparatus for
mounting lifting and connecting the operating mechanism of the cylinder flyer

page_text: apparatus of printing machines, and the arrangement of the parts in such a manner
as to give greater facilities of access to the type and cylinder than hitherto, and
consists in fixing pillars of small section in such position as to cause no obstruction to
the operator when "making ready" and on which are mounted the side plates of the
flyer apparatus so arranged as to effectually guide the same when moved up clear of
the impression cylinder or down in gear therewith for the removal of the sheets.
Across the machine supported by the pillars is a shaft on which are secured a hand
wheel and some grooved pullies two of which are of equal diameter and connected by
chains to the flyer apparatus, a third pulley is by preference of larger diameter and
has a chain and weight attached thereto for counterbalancing the flyer apparatus
so that on turning the shaft the apparatus is easily moved up or down the pillars.
In the class of printing machines known as the " Wharfedale" the cam bar for
operating the flyer is so located that it is clear of the operator, the connection between
the cam bar and flyer being accomplished by an interinediate bar being so arranged
that it may be easily engaged with or disengaged from the cam bar whenever required.
In describing my invention more in detail reference is made to the accompanying
drawings, in which
Fig. 1. represents such portions of the side elevation of a printing machine as are
required to show my invention.
Fig. 2. is a part plan of my improved apparatus somewhat enlarged, and
Fig. 3. is a part elevation of the same.
I fix on each cylinder stand A. a perpendicular pillar B. of small diameter or
section in such position as to cause no obstruction to the operator when "making
ready." The side plates C. of the flyer apparatus are prepared with long bossas D.
which embrace the pillars B. and effectually guide the apparatus when moved up
and down the pillars.
To the
Across the top of the said pillars is mounted a shaft E. on which is fixed a hand
wheel or spiked lever F. also two grooved pullies G. G. of equal diameter, and a third
pulley H. by preference somewhat larger in diameter in order to reduce the size of
the weight L. attached thereto in the manner as hereinafter described.
peripheries of the respective pullies G. G. are attached chains J. or their equivalents,
the lower ends of which are connected to the side plates O. of the flyer apparatus, and
to the periphery of the other and by preference larger pulley H. a chain K. having a
weight L. attached thereto is secured, which acting in conjunction with the other
pullies G. G. on the wheel and axle principle balance and facilitate the lifting of the
flyer frame C.
By means of a hand wheel or spiked lever F. the shaft E. is turned on its axis, and
the flyer apparatus placed in the desired position where it is retained by the weight L.
and in order to further secure it in an elevated position a catch wheel M. may be
secured on shaft E. and a pawl arranged to engage with the teeth of the wheel.
In the class of printing machines known as the "Wharfedale" as hitherto con-
structed the cam bar N. for giving motion to the flyer shaft and bars O, has been
located under or in close proximity to the said shaft, in which position it has
been found in practice to be of great obstruction to the operator when working at the
forme on the machine.
In carrying out this part of my invention the upright cam bar N. is mounted on a
stud placed near the cylinder away from the flyer shaft and out of the way of the
operator motion is imparted to the said bar by a rotating cam P. acting on a small
pulley mounted on the end of connecting rod Q. which is supported by a rocking
lever R. or other suitable means.
The top end of upright cam bar N. is reduced in section and engages with a slot
hole S. cut in the intermediate bar T. one portion of which is provided with a toothed
rack U. gearing with a toothed pinion V. secured on end of flyer shaft, so that on the
intermediate bar T. reciprocating on the supporting grooved pulley W. the flyer shaft
and bars O. attached thereto are operated for removing the sheets from the small
cylinder X. which is operated in the usual manner.
On lowering the flyer apparatus to the position shown by full lines, the inter-

page_text: mediate bar T. automatically engages with the end of cam bar N. by the reduced
end of the latter engaging in a slot holo S. so that the flyer bars O. are always
operated at the proper time for raising the sheets from the rotating tapes Z. operated
in the ordinary manner.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
1. The arrangement and combination of parts whereby a sheet delivery apparatus
may be moved towards or from the impression cylinder of a printing machine
substantially in the manner as herein before described, and illustrated by the accom-
panying drawings.
2. The combination of shaft E. pullies G and H. weight I. with the delivery
apparatus of a printing machine for the purpose herein before set forth.
3. The combination of the upright cam bar N. with the reciprocating rack bar T.
and toothed pinion V. arranged substantially in the manner and for the purpose herein-
before set forth.
