Year: 1872

page_text: LETTERS PATENT to James Morris, of Liverpool, in the County of
Lancaster, Printer, for the Invention of "IMPROVEMENTS IN AND
CONNECTED WITH MACHINES FOR FINISHING PRINTED SHEETS OF PAPER."
Scaled the 6th December 1872, and dated the 7th June 1872.
PROVISIONAL SPECIFICATION left by the said James Morris at the
Office of the Commissioners of Patents, with his Petition, on the
7th June 1872.
I, JAMES MORRIS, of Liverpool, in the County of Lancaster, Printer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN AND CONNECTED WITH MACHINES FOR FINISHING PRINTED SHEETS OF PAPER," to
be as follows:-
My Invention relates to improvements in and connected with the
-machines or apparatus for which Her Majesty's Letters Patent No. 1746
of the year 1868 were granted to me, that is to say, machines so
constructed that to facilitate finishing the printed sheets of paper are

page_text: passed through, between, and in direct contact with rotating smooth rolls
called "set-off rolls," and consists,—
First. As means for coating the ink "set-off" on the rolls uniformly
with whiting or other powdery matter, in giving a vibrating or joggle
motion to the container in such manner that the whiting or other matter
is caused to escape therefrom and reach the rolls in a shower. Tappets
fitted on a rotating shaft arranged to act on jointed levers carrying a
perforated container are well adapted for this purpose.
.
Second. As means for ensuring that only whiting or other powdery
matter of sufficient fineness reaches the rolls in the required quantity, 1
I enclose the said whiting or other powdery matter in a bag made of
textile fabric, and place the said bag in a perforated or openwork
container made to vibrate in accordance with the above first part of my
Invention.
Third. As means for effectually removing the ink "set-off" coated 1
with powdery matter from the rolls, I employ "take-off" buffing rolls
made to rotate in the opposite direction to the set-off rolls, or at a
greater surface speed. These take-off buffing rolls are constructed of a
large number of discs of calico or other woven fabric of about the
same diameter bound together on a spindle by end clamps.
Fourth. To keep the take-off buffing rolls constructed as above
described, or take-off rolls of any kind clean, I employ for each such
roll a cleaning brush made of bristles or strong fibres, such brush being
caused to rotate in contact with but in the opposite direction of the take-
off rolls.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Morris in the Great Seal Patent Office
'on the 7th December 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
MORRIS, of Liverpool, in the County of Lancaster, Printer, send 30
greeting.
WHEREAS Her most Excellent Majesty. Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of June, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-

page_text: fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said James Morris, Her special licence that
I; the said James Morris, my executors, administrators, and assigns, or
such others as I, the said James Morris, my executors, administrators,
and assigns, should 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 "IMPROVEMENTS IN AND CONNECTED WITH
MACHINES FOR FINISHING PRINTED SHEETS OF PAPER," upon the condition
(amongst others) that I, the said James Morris, my executors or admi-
nistrators, by an instrument in writing under my, 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 I, the said James Morris, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement :-
My Invention relates to improvements in and connected with the
machines or apparatus for which Her Majesty's Letters Patent No. 1746,
of the year 1868 were granted to me, that is to say, machines so con-
structed that to facilitate finishing the printed sheets of paper are passed
through, between, and in direct contact with rotating smooth rolls called
"set-off rolls," and consists,—
First. As means for coating the ink "set-off" on the rolls uniformly
with whiting or other powdery matter in giving a vibrating or joggle
motion to the container in such manner that the whiting or other matter
is caused to escape therefrom and reach the rolls in a shower. Tappets
fitted on a rotating shaft arranged to act on jointed levers carrying a
perforated container are well adapted for this purpose.
Second. As means for ensuring that only whiting or other powdery
matter of sufficient fineness reaches the rolls in the required quantity I
enclose the said whiting, or other powdery matter in a bag made of
textile fabric, and place the said bag in a perforated or openwork

page_text: container made to vibrate in accordance with the above first part of my
Invention.
Third. As means for effectually removing the ink "set-off" coated
with powdery matter from the rolls, I employ "take-off" buffing rolls
made to rotate in the opposite direction to the set-off rolls or at a greater
surface speed. These take-off buffing rolls are constructed of a large
number of discs of calico or other woven fabric of about the same
diameter bound together on a spindle by end clamps.
Fourth. To keep the take-off buffing rolls constructed as above
described, or take-off rolls of any kind clean, I employ for each such
roll a cleaning brush made of bristles or strong fibres, such brush being
caused to rotate in contact with but in the opposite direction to the
take-off rolls.
That my Invention may be more clearly understood I have appended
hereunto a Sheet of Drawings containing three views of a machine for
finishing printed sheets of paper in which my said several four improve-
ments are embodied.
Fig. 1 is an end view, one frame plate being removed.; Fig. 2, au end
elevation; and Fig. 3, an elevation of the delivery side. Like letters
denote the same parts in all the views.
1, framework; 2, smooth set-off rolls preferably made hollow and
heated by steam, say through the pipe 3; 4, weighted lever for regu-
lating the pressure of the top set-off-roll 2; 5, whiting or other .powdery
matter containers formed with perforations; vibrating motion is given to
the said containers by the gravity levers 6, the inner ends of which are
acted upon by the teeth of the wheels 7. Tappets can be employed for
made of woven fabric carried
giving motion to the containers. 8, bags
in the containers 5; 9, buffing rolls made of discs of calico or other
fabric bound closely together by the nut clamps 10, the said buffing
rolls rotating in the direction shown by the arrows. They may be made
to move differently, although I prefer the arrangements shown, the
object in all cases being to cause those rolls to move in the opposite
direction to the set-off rolls 2 at the surfaces of contact, or to cause
them to move at a higher surface speed. In all cases I prefer that the
surface speeds of 9 should be greater than the surface speeds of 2; 11
show intermediate wheels for giving motion to the buffing rolls 9 and
cleaning brushes 12. The cleaning brushes are made to move with a

page_text: greater surface speed at their circumference than the speed of the
surfaces of 9. They may rotate in cither direction relatively to the
buffing rolls 9, although I prefer that they should move in the opposite
direction. 13 are take-off rolls; they arc specially useful when highly
sized damp paper is being passed between or finished by the rolls 2; 14
are casings, with pipes 15 leading to an exhaust fan for drawing away
the dusty matter which otherwise would adhere to the surfaces of the
rolls 2 or pervade the atmosphere of the printing office; 16, feeding and
examining doors.
Having now described the nature of my said Invention, and particu-
larized the same in such manner that others will be enabled to carry my
improvements into effect, I claim,-
Under the first part, I. Coating the ink set-off on the rolls by whiting
or other powdery matter supplied in a shower, substantially as described
for the purpose set forth. II. The appliances under this head or their
equivalents, for the purpose set forth.
Under the second part,-Enclosing the whiting or other powdery
matter in a bag of textile fabric, and placing the same in a perforated
or openwork container made to vibrate, substantially as set forth and
delineated.
.
Under the third part,-I. The buffing rolls 9 for effectually removing
the ink set-off from the rolls 2, substantially as described. II. The end
nut clamps 10 for securing the discs of calico or other woven fabric on
their carrying shaft or spindle.
Under the fourth part,-The cleaning brushes 12, operating substan-
tially in the manner and for the purposes set forth.
In witness whereof, I, the said James Morris, have hereunto set
my hand and seal, this Sixth day of December, in the year of our
Lord One thousand eight hundred and seventy-two.
In the presence of
JAMES JOHNSON,
Clerk to J. T. King,
Liverpool.
