as follows:-
The Invention consists, firstly, in the employment of a revolving shaft
at the rear of the cylinder, the shaft having collars or rings fitted upon
it which bear upon the paper sheet and pass it from the cylinder to
endless bands, hereafter described. The shaft has an independent lifting
motion given to it by the cylinder to clear the cylinder. Whilst the
latter revolves intermittently the shaft travels the reverse way, and
takes hold of and delivers the sheets with the printed face upwards
on to the endless bands to be conveyed to the taking-off board.
The Invention consists, secondly, in arranging the revolving shaft.
of the band mechanism to move in slots to suit various sizes of
paper.
The Invention also consists in an arrangement of endless bands to the
machines referred to in the title, for the purpose of receiving the
printed sheets and of conveying them from the cylinder to the taking-off
board.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Charles Coleman and Albert Holman in the
Great Seal Patent Office on the 19th June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
CHARLES COLEMAN, of 88, Brook Street, Kennington Road, London,
Engineer, and ALBERT HOLMAN, of 113, Drummond Street, Euston
Square, London, aforesaid, Lithographic Printer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of December, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said John Charles Coleman and
Albert Holman, Her special licence, that we, the said John Charles
Coleman and Albert Holman, our executors, administrators, and
assigns, or such others as we, the said John Charles Coleman and
Albert Holman, our executors, administrators, and assigns, should

page_text: at any time agree with, and no others, from time to time and at
all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVED APPLIANCES FOR THE TAKING-OFF AND
DELIVERY OF PRINTED SHEETS FROM STOP CYLINDER LITHOGRAPHIC AND STOP
CYLINDER LETTER-PRESS MACHINES," upon the condition (amongst others)
that we, the said John Charles Coleman and Albert Holman, or one
of us, our executors or administrators, by an instrument in writing
under our, or one of our, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said John Charles Coleman and
Albert Holman, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement thereof,
reference being had to the Drawings hereunto annexed, that is to
say:
-
The Invention consists, firstly, in the employment of a revolving shaft
at the rear of the cylinder, the shaft having collars or rings fitted upon
it which bear upon the paper sheet and pass it from the cylinder on to
endless bands, hereafter described. The shaft has an independent
lifting motion given to it by the cylinder to clear the cylinder. Whilst
the latter revolves intermittently the shaft travels the reverse way, and
takes hold of and delivers the sheets with the-printed face upwards on
to the endless bands to be conveyed to the taking-off board.
The Invention consists, secondly, in arranging the revolving shaft
of the band mechanism to move in slots to suit various sizes of
paper.
Our Invention will be clearly understood by the following description
and by the accompanying Sheet of Drawings, in which Figure 1
shows in perspective a printing machine with a reciprocating or stop
cylinder, as before referred to, and Figure 2 a perspective view of our
Invention detached.

page_text: a is a shaft capable of revolving under the action of a band or cord b
by a pulley or band wheel c upon an under shaft d. The shaft a has
a number of collars or rings e, e, preferably of rubber or some yielding
composition or compound, or wood, upon it to press upon the body of the
stop cylinder fat the rear, and to bear upon the sheets of printed paper
as they pass from the cylinder to a series of endless tapes 9, 9, by which
they are carried to what is termed a "taking-off board" h, this being at
the end of the printing machine, as shown at Figure 1. The shaft a is
capable of a slight lifting motion in the side frame or brackets j to
accommodate itself for the collars or rings to clear the cylinder while it
revolves for the printing operation, but to return and bear against it on
the reverse motion of the cylinder to take hold of the printed sheets
and deliver them printed face uppermost. The gut band or cord 6 by
which this shaft is driven always in the same direction passes over or
around pullies on a separate shaft k by which the endless tapes g, g, are
actuated, the tapes running in grooves in another shaft / to preserve
their parallel action.
We do not limit ourselves to the exact method shown of fitting a
shaft with collars or rings to a stop cylinder printing machine, nor to
the precise number of collars or rings thereon, as both the position of a
the shaft and the number and positions of the collars or rings thereon.
can be changed to suit the particular construction of printing machine
to which the shaft may be applied.
The Invention also consists in the arrangement of endless bands to
the machine, referred to in the title, for the purpose of receiving the
printed sheets and for conveying them from the cylinder to the taking-
off board, as shown.
And having now described the nature of our said Invention, and
in what manner the same is to be performed, we declare that we
claim,―
The employment of a shaft in proximity to the cylinder of a stop
cylinder lithographic or stop cylinder type printing machine, such shaft
having collars or rings to bear upon the cylinder to act as guides for
directing the sheets from the cylinder to a taking-off apparatus, as
described and substantially as shown in the Drawings.
Secondly. We claim fitting a sheet-receiving apparatus on or above
the level of the top side frames and between the cylinder and the taking-

page_text: off board of a stop lithographic or a stop type 'printing machine, as set
forth, such receiving apparatus being composed of endless bands upon
rotating, shafts, as described and shown.
Thirdly. We claim the combination of the taking-off shaft with
collars and the endless bands receiving or delivering apparatus working
in unison therewith, when applied or arranged with stop cylinder
lithographic or stop cylinder letter-press printing machines, as described.
In witness whereof, we, the said John Charles Coleman and
Albert Holman, have hereunto set our hands and seals, this
Eighteenth day of June, One thousand eight hundred and
seventy-five.
