PROVISIONAL SPECIFICATION.
A Means of Dividing Paper as it is being Formed into a Continuous
Length on a Paper Making Machine into Two or More Narrow
Lengths.
I, WILLIAM PATRICK BRUCE of Kinlieth, in the County of Midlothian,
Paper Maker, do hereby declare the nature of this invention to he as follows:-
In the Specification of a Patent granted to me on the 7th day of April 1885,
No. 4300, I described a method of dividing or partially dividing finished lengths of
paper as they are being formed on paper making machines into two or more
narrower lengths by means of jets of water directed against their surface.
I have since discovered that this result can be obtained more advantageously by
the use of jets of fluid lighter than water such as jets of air, steam or like aeriform
fluid or by jets of air or like aeriform fluid carrying along with them a small
quantity of water or other liquid in the state of minutely divided spray.
Dated this 2nd day of December 1890.

COMPLETE SPECIFICATION.
A Means of Dividing Paper as it is being Formed into a Continuous
Length on a Paper Making Machine into Two or More Narrow
Lengths.
I, WILLIAM PATRICK BRUCE, of Kinlieth, in the County of Midlothian, Paper
Maker, 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 :-
In the Specification of a Patent granted to me on the 7th day of April 1885,
No. 4300, I described a method of dividing or partially dividing finished lengths
of paper as they are being formed on paper making machines into two or more
narrower lengths by means of jets of water directed against their surface.
I have since discovered that this result can be obtained more advantageously
by the use of jets of fluid lighter than water such as jets of air, steam or like
aeriform. fluid or by jets of air or like aeriform fluid carrying along with
them a small quantity of water or other liquid in the state of minutely divided
spray.
In carrying out my invention I prefer to form the jets as described in the
Specification of my former Patent of soft metal pipes about of an inch in
diameter tapered at the outlet end to reduce the outlet orifice to a size such as
would be made by an ordinary darning needle. The pipes are carried by a bar or
frame fixed across the machine above the wire web which carries the paper-the
outlet ends of the pipes being brought close down to the paper say to within
about inch more or less of its surface. Each pipe may be carried by a slide
capable of being moved along the bar or frame so that it may be set in any
required position.
Each pipe or nozzle is connected by an india rubber tube to a supply of air
or steam under pressure-preferably I use & pressure of about 8 to 10 lbs.
to the square inch when the jets are set at about inch from the surface of
the paper.
The jets may as described in the Specification of my former Patent be applied
in such a way as only partially to divide the paper and the division of the paper
Pine 11

page_text: be completed after the paper has passed the couch roll and before it comes to
the drying cylinders-this may be effected by causing the paper where it is
partially divided to be brought against a fixed cutter something in the form of a
paper knife.
.
When a jet of aeriform fluid carrying along with it a small quantity of liquid
in the state of minutely divided spray is to be used the jet of aeriform fluid just
as it issues from a nozzle may be made to pass across the end of a small nozzle
through which liquid is supplied and so to carry along with it a small quantity
of the liquid.
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 :-
--
•-
Dividing or partially dividing continuous lengths of paper as they are being
formed on paper making machines into two or more narrower lengths by means
of jets of air or steam or like aeriform fluid lighter than water or by jets of
aeriform fluid carrying along with them a small quantity of water or other liquid
in the state of minutely divided spray and directed against the surface substantially
as described.
Dated this 3rd day of August 1891.
