I, FREDERICK PAYNE of the firm of Payne and Sons of Otley, Yorkshire,
Machine Makers do hereby declare the nature of my invention for "IMPROVE-
MENTS RELATING TO THE FEEDING MECHANISM OF A CERTAIN CLASS OF CYLINDER
PRINTING MACHINE," to be as follows:-
:-
This invention has reference to that class of printing machine technically called
'large cylinder" or one revolution perfecting machine" and my improvements
relate to the feed mechanism which has hitherto been effected by complicated
mechanism, consisting of a feed drum placed at a position near the top of the first
impression cylinder, necessitating that the person who fed the machine should
stand on a platform in an elevated position which was not only inconvenient but
injurious to health in consequence of the temperature of a room always being
much higher near the ceiling than below, especially is this apparent when gas
is used.
My invention consists in dispensing with the feed drum, and in arranging
mechanism so as to feed direct onto the first impression cylinder near the under-
side thereof, making the feed at a point where the person attending the machine
can stand upon the ground.
"
To carry out my invention in this class of machine I attach to the first
impression cylinder a set of "grippers" which during a certain part of a revolution
of the said cylinder the "grippers" are caused to open and seize hold of a sheet of
paper and carry it forward to be impressed-when this is done the "grippers'
release their old and the paper is carried by a double tape over the ordinary
register drums, which convey the said paper to the second impression cylinder
which is also provided with "grippers" for seizing hold of the paper to be again
impressed.
By the employment of mechanism such as is herein set forth, I am enabled to
dispense with the ordinary feed drum and parts connected therewith, also avoid
the necessity of having the feeding board above the machine, and I also dispense
with one carrying tape of each cylinder.

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 "IMPROVE-
MENTS RELATING TO THE FEEDING 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 printing machine technicially called
"large cylinder or one revolution perfecting machine" and my improvements
relate to the feed mechanism which has hitherto been effected by complicated
mechanism consisting of a feed drum placed at a position near the top of the first
impression cylinder, necessitating that the person who fed the machine should
stand on a platform in an elevated position which was not only inconvenient but
injurious to health, in consequence of the temperature of a room always being
much higher near the ceiling than below, especially is this apparent when gas
is used.
My invention consists in dispencing with the feed drum, and in arranging
mechanism so as to feed direct into the first impression cylinder near the outside
thereof, making the feed at a point where the person attending the machine can
stand upon the ground.
To carry out my invention in this class of machine I attach to the first
impression cylinder a set of "grippers" which during a certain part of a revolution
of the said cylinder the "grippers" are caused to open and seize hold of a sheet
of paper and carry it forward to be impressed when this is done, the "grippers'
release their hold, and the paper is carried by a double tape over the ordinary
register drums, which convey the said paper to the second impression cylinder,
which is always provided with "grippers" for seizing hold of the paper to be again
impressed.
In order that my invention may be better understood I herein make reference
to the accompanying sheet of drawings which is side elevation of a large cylinder
or one revolution perfecting machine. A is framing of machine, B driving shaft,
C the the inner or first impression cylinder, D the outer or second impression
cylinder, and E and F are the register drums. As previously stated the object of
this invention is to dispense with the ordinary feed drum usually placed near the
top of the first impression cylinder C and to feed the sheets of paper direct to the
said cylinder, and this I effect by placing the feed board G in the position shewn
in the drawings or such other suitable position as the paper can be received by and
carried under the first impression cylinder C, which is provided with grippers a for
seizing hold of the paper. Single tapes b and c are employed which partially pass
around each impression cylinder and around the register drums, but the two tapes
meet at point d¹ and run together until they reach the grippers e on the second

page_text: impression cylinder when the tapes separate and the said grippers seize hold of
the paper, and carry it forward for a second or perfectly impression.
The action of the machine is as follows;
The sheets of paper are placed upon the feed board G and are fed one by one
to the grippers a which seize hold of the paper and hold it until printed, and when
the paper arrives at the point d, the grippers release their hold of the paper but
the double tapes carry it over the register drum E, and under the register drum F,
when the grippers e on the second impression cylinder seize hold of the paper and
carry it forward, for the second or perfecting impression.
After this operation the grippers take the paper for ward to thedouble tapes
at d' and on releasing their hold of the paper it is again taken by the tapes over
and under the register drums E and F where studs are raised (by means of
stationary cam H) sufficient as to raise and present the paper to the grippers g on
the taking off drum I, which gripper g receives the paper and passes it forward
over the drum J, down the flyer tapes h, on to the flyer K, when it is deposited
upon the receiving board L
Although I have shewn and described my improved system of feeding as applied
to a machine having reduced wheels, and delivering the paper beyond the second
impression cylinder as set forth in my Specification of Patent No 10,591, of 1885,
it must be understood that the method of feeding a large cylinder or one revolution
perfecting machine may be applied to machines made on the old system, when the
delivery takes place at a point between the first and second impression cylinders.
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 In a large cylinder or one revolution perfecting machine the employ-
ment of " "grippers on both the first and second impression cylinders, in the
manner and for the purpose set forth.
Secondly-In combination with grippers on the first Impression cylinder the
employment of a feed board below the centre of the first impression cylinder
thereby I am enabled to feed the sheets of paper direct to the grippers on said
cylinder and so dispense with the feed drum hitherto placed near the top of the
first Impression cylinder.
