I, FREDERICK PAYNE of the firm of Payne and Sons of Otley, Yorkshire,
Machine Makers do hereby declare the nature of my invention for "IMPROVEMENTS
RELATING TO THE DELIVERY MECHANISM OF A CERTAIN CLASS OF CYLINDER
PRINTING MACHINE," to be as follows:-
This invention has reference to that class of cylinder printing machine commonly
called "large cylinder or one revolution perfecting machine" and my improvements
therein relate to the delivery of the sheets of paper after being printed, which have
hitherto been delivered onto a table at a point between the two cylinders,
consequently the cylinders have had to be set a wide distance apart, necessitating
driving wheels of large diameter and making the machine unnecessarily long.
My invention consists in delivering the paper at a point outside the second
impression cylinder, and this I.accomplish by carrying the sheet of paper after the
second impression is made, back again over the register drums and back to the top
of the second impression cylinder, when a set of fingers attached thereto open out,
and throw the paper off the cylinder onto a roller and carrying tapes which deliver
the paper to a flyer to be deposited onto a delivery board.
This arangement of delivery enables me to bring the cylinders close together,
consequently the driving wheels are reduced to about the same diameter as the
cylinder,, which is not only a great saving in the size of wheels, but I am
enabled to drive the usual register drums off one of the said wheels, consequently
one large wheel which was hitherto employed to drive the said register, drums is
now dispensed with.
To persons conversant with these machines great advantages will be seen in
reducing the diameter of the driving wheels which have hitherto been of such a
size as to practically cover up one whole side of the machine, rendering it almost
impossible to get to the internal parts without risk, whilst in addition to this the
space occupied by these machines will be considerably less which is sometimes a
desirable object to attain.

page_text: Improvements relating to the Delivery Mechanism of a Certain
Class of Cylinder Printing Machine.
I FREDERICK PAYNE, of the Firm of Payne and Sons, of Otley, Yorkshire,
Machine Makers do hereby declare the nature of my invention for "IMPROVEMENTS
RELATING TO THE DELIVERY MECHANISM OF A CERTAIN CLASS OF CYLINDER
PRINTING MACHINE," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This invention has reference to that class of cylinder printing machine commonly
.called "large cylinder or one revolution perfecting machine" and my improvements
therein relate to the delivery of the sheets of paper after being printed which have
hitherto been delivered onto a table at a point between the two cylinders
consequently the cylinder have had to be set a wide distance apart, necessitating
driving wheels of large diameter and making the machine unnecessarily long.
My invention consists in delivering the paper at a point outside the second
impression cylinder; and this I accomplish by carrying the sheet of paper after
the second impression is made back again over the register drums, and back to the
top of the second impression cylinder when a set of fingers attached thereto open
out, and throw the paper off the cylinder onto a roller and carrying tapes, whicți
deliver the paper to a flyer to be deposited onto a delivery board.
Such being the nature and object of my invention I will now proceed to describe
the same more fully and for that purpose make reference to the accompanying
sheet of drawings which is side elevation of a large cylinder or one revolution
perfecting machine having my improvements applied thereto, A is framing of
machine, B main driving shaft, C feed board, D the first impression cylinder, and E
the outer or second impression cylinder which it will be observed are brought close
together and driven by gear wheels, motion being imparted thereto by other gear
wheels F and G from the main shaft B.
:
By these means I am enabled to remove the delivery table (which has hitherto
been placed between the two cylinders D and E) to a position outside the second
impression cylinder E as shewn at H, consequently the driving wheel for each
cylinder is much reduced in diameter.
I and J are register drums the former of which is driven from the driving wheel
of the first impression cylinder, K are flyer tapes passing around the drum I
employed for taking the printed sheet of paper from the taking off drum L', and M
is the flyer employed for transferring the sheet of printed paper from the tape K
to the delivery table H.
:
The modus operandi is as follows: The sheets of paper are fed from the feed
board C and seized by grippers on the inner or first impression cylinder D, and
held thereby until printed when the grippers release their hold of the paper, after
which it is taken by the tapes a and b which at point c run double and take the
paper over the register drum I, and under register drum J, where it is seized by
grippers & on the second impression cylinder E which holds the sheet during the
second or perfecting impression, after which the sheet is released by the grippers

page_text: and passed to the double tapes at c which conduct the paper over and under the
register drums I and J until it gets to the studs e which are raised at this point by
the cam N fixed to the framing of the machine.
The studs at this point rise and lift the paper so that it is seized by the
grippers on the taking off drum L' passed over the drum L and from thence to
the tapes K, and finally transferred by flyer M to the delivery board H.
This arrangement of delivery enables me to bring the cylinders close together,
consequently the driving wheels are reduced to about the same diameter as the
cylinder, which is not only a great saving in the size of wheels, but I am enableḍ
to drive the usual register drums off one of the said wheels, consequently one
large wheel which was hitherto employed to drive the said register drums is now
dispensed with.
To persons conversant with these machines great advantages will be seen in
reducing the diameter of the driving wheels which have hitherto been of such a
size as to practically cover up one whole side of the machine, rendering it almost
impossible to get to the internal parts without risk, whilst in addition to this the
space occupied by these machines will be considerably less which is sometimes a
desirable object to attain.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim as my invention is
Firstly. Driving the first and second impression cylinders of large cylinder
perfecting machines by means of gear wheels of the same, or nearly the same
diameter as the cylinders, in manner and for purposes substantially as herein shewn
and described.
Secondly. The construction of large cylinder perfecting machines where. the
cylinders are driven by wheels of the same diameter, and the delivery board placed
at a position outside the second impression cylinder substantially as shewn.
Thirdly. The means herein shewn and described of driving the register drum I
direct from the first impression cylinder.
