PROVISIONAL SPECIFICATION.
Improvements in the Manufacture or Treatment of Paper.
I, ALGERNON YOCKNEY of Woodbine Cottage, Wilcove in the County of
Cornwall Fleet Paymaster, Royal Navy do hereby declare the nature of this
invention to be as follows:-
-
The object of my invention is to so prepare or treat paper that it will not become
deteriorated but will remain intact and undeteriorated even in the hottest and
dampest climates. According to my invention I employ in the manufacture or
treatment of paper boracic acid or a compound or derivative of boracic acid such
as boron or borax. The said boracic acid or compound or derivative of boracic
acid may be added to the paper pulp or half stuff at any convenient stage of the
manufacture for instance it may be added to the size or it may be added after the
paper has been made into a web or sheets by passing the web or sheets through a
vessel containing a solution of the boracic acid or derivative or compound thereof.

COMPLETE SPECIFICATION.
Improvements in the Manufacture or Treatment of Paper.
I, ALGERNON YOCKNEY of Woodbine Cottage, Wilcove, in the County of
Cornwall, Fleet Paymaster, Royal Navy 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 :-
The object of my invention is to so prepare or treat paper that it will not become.
deteriorated but, with ordinary care, will remain intact and undeteriorated even in
the hottest and dampest climates. According to my invention I employ in the
manufacture or treatment of paper boracic acid or a compound or derivative of
boron such as borax or a mixture of any of the compounds of boron with other
substances. The said boracic acid or compound or derivative of boron or the like as
above stated may be added to the paper pulp or half stuff at any convenient stage of
the manufacture for instance it may be added to the size or it may be added
after the paper has been made into a web or sheets by soaking the paper in, or
passing the web or sheets through a vessel containing a solution of the boracic acid
or derivate or compound of boron or the like as above stated.
I do not limit myself to any particular method of applying the solution of
boracic acid or derivative of boron or the like as above stated. I prefer to employ
an amount of acid or compound of boron or the like as above stated making a
solution not weaker than one part of acid in 120 parts or thereabouts of the
solution.
A sizing to be applied to the paper, or to be used in making the paper, may be
prepared by taking gelatine and adding to each ounce of gelatine a quart of water
and allowing the gelatine to soak therein for say about twenty four hours and then
boiling until the gelatine dissolves in the water, the receptacle should then be closed
by, say, a plug of cotton wool, and about 24 hours afterwards it may be boiled a
second time without removing the plug and after another twenty four hours or
thereabouts it may be similarly boiled again. To each ounce of the jelly thus

page_text: made add one ounce of a solution of boracic acid of 20 grains of acid to an ounce
of water, taking care that the acid is thoroughly mixed with the gelatine the
resulting mixture having of course 10 grains of boracic acid to the ounce.
mixture may however be made wenker or stronger if desired but generally I find
the above answers well.
The
The size when thus prepared with a solution of boracic acid (or compound or
derivative of boron as above stated) will remain good and free from mildew and
liquification for a very considerable period while size not so prepared deteriorates
in a very short period. With ordinary care size thus prepared will be practically
imperishable and most suited for the preparation of all kinds of glazed or sized
papers, drawing papers, account book or other papers and all kinds used for
records or wall papers. Paper thus prepared will be more especially valuable to
artists, architects, bankers and others in tropical climates where at present there is
the greatest difficulty or impossibility in keeping paper good and I believe no
paper hitherto in the market will stand a tropical climate.
With this preparation valuable old drawings or the like may be resized and
worked on and restored and also be rendered safe under all circumstances to be
taken to tropical climates or damp hot places, or near the sea.
In the preparation of the size the ingredients should be well boiled and distilled
water should preferably be used for any solution of the acid for use with or without
the size.
The boracic acid or the compound or derivative of boron as above stated will not
injure the most susceptible colors or injure the paper or render it unsuitable for any
purpose required.
The solution of boracic acid should preferably not be of a less strength than
above stated but a stronger solution may be used to allow for absorption by damp.
When sizing the paper the size should be kept and maintained well stirred and
mixed so as to insure perfect mixture.
I do not limit myself to any particular way of applying the boracic acid or
compound or derivative of boron or the like as above stated for instance it may be
mixed with the colouring or distempering used for wall papers or other papers.
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 :-
.
In the manufacture or treatment of paper the use of boracic acid or a compound-
or derivative of boron such as borax or a compound or mixture of any of the
compounds of boron with any other substance substantially as hereinbefore
described.
