Certain Improvements in Cylinder Printing Machines.
I, FREDERICK PAYNE, of the firm of Payne and Sons, of Atlas Works, Otley,
Yorkshire, Machine Makers, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to that class of cylinder printing machines commonly
termed "large cylinder or one revolution perfecting machines." In this class of
machine it has hitherto been customary to employ a single or double set of tapes for
guiding or holding the paper in position around the impression cylinders and register
drums employed, but to the use of tapes and register drums there are many objections,
and the object of my present invention is to dispense with such tapes and register
drums and employ instead thereof a second set of grippers on second impression
cylinder, and a detaining cylinder also fitted into a set of grippers which receive
the sheets of paper to be printed upon at given times and release their hold of the
said paper to be afterwards received by other grippers.
In carrying out my invention the first impression cylinder is provided with a set
of grippers which receive a sheet of paper from the ordinary feeding board of the
machine, and which grippers hold the paper until the cylinder has passed the paper
over the type, where the paper receives its first impression, and when the front edge
of the paper has arrived in a horizontal line to the axis of the said cylinder, or at
any other convenient point, the said paper is taken hold of by the second set of
grippers connected to the outer or second impression cylinder, immediately after
which the grippers of the first impression cylinder release their hold of the paper,
when the said paper is carried around by the second set of grippers on the second
impression cylinder to be taken hold of by grippers attached to a detaining cylinder,
which receives and holds the paper until the first set of grippers on the second
impression cylinder come into position to receive the said paper from the detaining
cylinder, when the said paper is carried down by the first set of grippers and passes
over the type to receive the second impression, the said grippers retaining their
hold upon the paper until it arrives at the flyer drum, which receives the paper by

page_text: grippers, when the paper is next received by an ordinary flyer and transferred onto
the delivery table of the machine, or instead of the paper being received by a
flyer it may be received by an inclined delivery board. The grippers on the second
impression cylinder are, by means of cams or other equivalent devices, caused to
advance from the depressed part of cylinder to receive the paper from the first
impression cylinder.
By dispensing with the ordinary tapes and register drums employed in this class
of machinery, the inconveniences caused by the stretching of the tapes are avoided,
and the machine simplified.

Certain Improvements in Cylinder Printing Machines.
I, FREDERICK PAYNE, of the firm of Payne and Sons, of Atlas Works, Otley,
Yorkshire, Machine Makers, 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 has reference to that class of cylinder printing machines commonly
called "large cylinder or one revolution perfecting machines." In this class of
machine it has hitherto been customary to employ a single or double set of tapes for
guiding or holding the paper in position around the impression cylinders and register
drums employed, but to the use of tapes and register drums there are many objections,
and the object of my present invention is to dispense with such tapes and register
drums and employ instead thereof a second set of grippers on second impression
cylinder, and a detaining cylinder also fitted with a set of grippers which receive
the paper to be printed upon at given times and release their hold of the said paper
to be afterwards received by other grippers.
ог
In order that my invention may be better understood, I will now proceed to
describe the same more fully, and for that purpose make reference to the annexed
sheets of drawings illustrative thereof, wherein Fig. 1 represents a large cylinder
one revolution perfecting printing machine with my improvements applied
thereto. A is the framework of the machine, B the type or formes, the first
impression cylinder, D the second impression cylinder, E the flyer drum, and F an
additional roller which I choose to term a detaining cylinder. The paper to be
printed upon is placed onto the feed board G from whence it is removed by
grippers a connected to the first impression cylinder which revolves in the direction
of the arrow, whereby the paper is rolled upon the type to receive the first
impression, and by the time the grippers a on. the first impression cylinder arrive
at the position shewn in the drawings, the said paper is taken hold of by an additional
or second set of grippers 6 connected to the second impression cylinder D, which
second grippers carry the paper to the detaining cylinder F when a set of grippers c
thereon takes the paper from grippers which it detains by revolving with the paper
until the grippers d on the second impression cylinder come around for the purpose
of taking-hold of the paper and rolling the unprinted side thereof on the type or
forme, by which means the second impression is given to the paper, which is after-
wards carried to the flyer drum E when the grippers e thereon receive the paper and
carry it to the ordinary flyer H which transfers it to the delivery table I.
The several sets of grippers are opened and closed in the ordinary manner,
but those marked b on the second impression cylinder are raised above the depressed
surface of the second impression cylinder by means of stationary cams J and K. The
grippers are carried on the end of a rod or arm carrying a bowl g at its lower
extremity, which bowl rides upon the said arms J and K at the time the grippers
are required to be in use, the spiral spring being employed to draw the grippers

page_text: back after the bowl on the bottom of the rod has left the cams.
When the grippers b
have carried the paper to the detaining drum F, the said grippers are operated
by the cam L so as to give the paper to the grippers c on the said detaining
drum, but the grippers d are operated by the cam M for giving the paper to the
flyer drum E.
Instead of the paper being received by the flyer H, it may be received by an
inclined delivery board N as shewn at Fig. 2 where E is the flyer drum and I are
endless bands between which the paper is carried for the purpose of being deposited
on the delivery board N.
By the application of grippers to the first and second impression cylinders as herein
shewn and described, paper is received from the feed board and printed upon both its
sides and carried to the flyer drum without the use of tapes, which has not hitherto
been accomplished in this class of machine; which prevents the inconveniences caused
by the stretching of tapes.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is
Firstly. In one revolution perfecting machines, the peculiar arrangement of
grippers on the printing cylinders whereby the paper is printed upon both its sides
without the employment of tapes, all arranged substantially as described and shewn in
the drawings.
Secondly. The employment of a detaining drum such as F in combination with the
second impression cylinder having two sets of grippers, arranged substantially as
shewn and described.
