PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Paper.
JAMES CRAIG, Lime Grove Terrace, Cheadle, Cheshire Agent do hereby declare
the nature of this invention to be as follows:-
In punching out suitable patterns or designs in the paper during manufacture,,
whereby the said suitable patterns or designs may be shewn in a duplex or triplex
paper in the manner hereinafter described-by passing the paper from the cylinders.
of a paper making machine between the punching rolls. A & B, which is then reeled
on to D. This. reel is afterwards placed at E or F, and either of them is used_in
making duplex paper by running it on the top or underneath the wet pulp. H. For
triplex. paper both reels. E & F being different colours, and different patterns or
designs if required, are used; and while the duplex or triplex paper is being made,
the punching roll B is, raised by means of C. to allow the paper to pass-or this
paper can be made, on another paper machine., G. G. are spare reels. H is the.
wet pulp.
COMPLETE SPECIFICATION.
Improvements in the Manufacture of Paper.
JAMES CRAIG, Lime Grove Terrace, Cheadle, Cheshire, Agent,, 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, references,
being given to the Drawings filed with my Provisional Specification as well as to, the,.
sheet of Drawings filed herewith :-
For improvements in the, manufacture, of paper in punching out. suitable patterns. .
or designs. in the paper during manufacture whereby the said suitable patterns, or
designs may be shewn in a duplex or triplex paper in the manner hereinafter.
described, by passing the paper from the cylinders of a paper making machine.
between the punching rolls A & B which is then reeled on to D. This. reel is.
afterwards placed at. E or F and either of them is used in making duplex paper by..
running it on the top or underneath the wet pulp H. For triplex paper both
reels E&F being different colours and different patterns or designs if required are
used and while, the duplex or triplex paper is being made the punching roll B. is
raised by means of C to allow the paper to pass or this paper can be made. on
another paper making machine., G. G. are spare rolls. H is the wet pulp.
The roll marked A Fig. 1 on the Drawing herewith may be made of cast iron,
steel, brass or other suitable material and may be composed of sections or made in
one piece.. These sections, or the one piece when used in connection with hollow
punches marked "C" on the roll B. Fig. 1 may be covered with paper wood
gutta percha or other suitable material in order to give a good cutting surface.
The said roll A in sections; or in one piece when used in connection with solid
punches marked "6" on Drawing herewith on said roll B will have the necessary
suitable holes marked "a" on the Drawing herewith as may be required for the
said punches to make the required pattern or design. The said roll B may also be.
made of cast iron, steel, brass, or other suitable, material and also may be composed
of sections of suitable sizes or made in one piece. The body of said roll B. as
marked "6" on the Drawing herewith may be about one inch in diameter less than
at each end, according to the length of the punches.. The punches marked “64 & 6²?
on said roll B will be made to project sufficient to punch through the necessary.
[Price 8d 1

page_text: thickness of paper. The said punches may be made of brass, steel, or other suitable
material in round, square, or other suitable shape and fixed in the said roll B by
being screwed into suitable holes therefor or may be fixed in suitable grooves cut
into the body of the said roll B. The said rolls A & B when made in sections are
mounted on round or square axles made of iron steel brass or other suitable material
and keyed or wedged up in the usual manner. When these said rolls A & B are
made in one piece the gudgeons thereof will form a solid part thereof or may have
steel or iron axles. The said axles are mounted in the usual manner in the frame-
work as shewn in the Drawing herewith. This framework may be attached to the
framework of the paper making machine in any manner as may be found most
suitable or may be separate from the paper making machine and used in another
suitable part of the building having suitable driving gear attached thereto so that
one or more thicknesses of paper may be punched at the same time. On the far
side (that is the side on which the driving power of the paper making machine is
placed) is mounted on the axle of roll A a suitable spur wheel marked "a" on the
Drawing herewith keyed thereto in the usual manner, and on a continuation of the
same axle outside of the said spur wheel is also mounted and keyed thereto in
the usual manner a suitable pulley to give the required motion and speed to roll A.
When working and attached to the paper making machine this pulley is driven in
the usual way by a suitable belt working another pulley from another part of the
paper making machine. On the far side of the said roll B is also mounted on the
axle thereof and keyed thereto in the usual manner a suitable spur wheel marked " 63"
on the Drawing herewith, working into and driven by the spur wheel on roll A.
These spur wheels may not be required as the friction of roll A may drive roll B.
Above the said roll B an axle marked C on the Drawing herewith is mounted in
suitable guides marked "C" on the Drawing herewith in the usual manner, on each
end of which is attached and keyed thereto are suitable cams marked "C1" on the
Drawing herewith. The said axle marked C working in said guides attached to the
top of the frame on the Drawing herewith. Over the said axle C is passed a suitable
strap marked "C" on the Drawing herewith made of iron brass steel or other
suitable material the ends of which are fixed by means of a screw-bolt passing
through the said straps and a projection on the brasses of the said roll B as shewn in
Figs. 4 & 5 on the Drawing herewith. By means of part of a revolution given to the
said axle C by means of a wheel marked "C" on the Drawing herewith the centre
of the said cams "C" and the said strap "C3" the roll B may be sufficiently raised
and the spur wheels "a2" & "63" be still in gearing to allow the paper to pass.
between the said rolls A & B without being punched as shown in Fig. 5 on the
Drawing herewith. The punched paper after passing between the rolls A & B is
then reeled up in the usual manner and marked D on the Provisional Drawing
lodged with the Provisional Specification. This reel of punched paper is then
mounted and secured in the usual manner at the most suitable place marked Ę in
the said Drawing with the Provisional Specification, and in conjunction with, and on
the top of the paper pulp marked H on the Drawing with the said Provisional
Specification forms the duplex paper, and shewing a pattern or design, another reel
of punched paper marked F. on the Drawing with the Provisional Specification is
also mounted and secured in the usual manner and in the most suitable place and
in conjunction with and underneath H & E in the Drawing with the Provisional
Specification forms the triplex paper, shewing the same or another pattern or design
in the same or another colour, the said duplex or triplex paper passes between the
said rolls A & B, the roll B being previously raised until again required for punching.
This punching machine may be made of any width to suit the paper making machine
with which it is to work, the rolls A & B may be of any diameter to suit the
required design or pattern to be punched.
Fig. 1 shews the rolls, frame, and cam axle complete or shews the punching
machine complete in elevation.
Fig. 2 shews plan of same.

page_text: Fig. 4 shews roll A in working position the cam being at rest.
Fig. 5 shews roll A raised up by cam to allow paper to pass through.
Figs. 4 & 5 also shew the strap attached to brass bearing.
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 I
claim is
1. Punching suitable patterns or designs in a web of paper during the process of
manufacture.
2. The manufacture of a duplex paper shewing one or more suitable patterns or
designs. Novelty is not claimed for a duplex paper which does not show a pattern
or design.
3. The manufacture of a triplex paper shewing one or more suitable patterns or
designs which may or may not have the same colour patterns or designs on each
side thereof.
