Improvements in the Manufacture of Toilet-paper.
I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:-
My invention relates to toilet-paper and comprises the improvements hereinafter
specified.
An important feature of my said invention is the manufacture of toilet-paper having
an irregular or roughened surface, that is to say, toilet-paper having indentations or
impressions formed in the surface of the paper by reason of which the said toilet-paper
may be made of a superior quality, or from the best stock and will nevertheless be free
froin the objectionable features of the hotter grades of toilet-papers viz. :-those of
excessive smoothness and the difficulty experienced in separating single sheets from a
pack or bundle of the same on account of the separate sheets.adhering to each other.
My improved toilet-paper moreover possesses other advantages hereinafter specified.
In manufacturing toilet-paper according to my said invention I find the following
method of procedure convenient and advantageous. After the said paper has been
made as heretofore and before leaving the machine, it is passed between a roll covered
with wire cloth, or a roll provided with projections on its outer surface, and another
roll covered with felt. The wire cloth or the projections on the said roll enter the
surface of the paper and form the afore-mentioned impressions or indentations. Toilet-
paper so treated is rendered softer and more agreeable to use and furthermore, on
account of the depressions, water will act on it to better advantage to dissolve or break
or separate it into fragments than if it had an oven or smooth surface. Consequently
the said paper is less liable to clog drain pipes than those papers of the thicker and
cheaper grades or than those of the better qualities having smooth surfaces. Further-
more, by stretching or drawing the fibres of the said paper in the act of forming the
said indentations or impressions a large proportion of the chemicals, used in the
treatment of the stock, that have been retained by the paper, and which are injurious,
are removed or forced out.
In making my improved toilet paper it is necessary to use the best stock or materials
in order to produce a paper that will be sufficiently tough to receive and retain the
indentations or impressions without rupturing the fibres; the paper being therefore of
necessity much stronger than that made from inferior stock or materials and it is more
economical in use.

Improvements in the Manufacture of Toilet-paper.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex, 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:--
My invention relates to toilet paper and comprises the improvements hereinafter set
forth

page_text: S
Toilet-paper has heretofore been usually made from the cheaper or poorer qualities
of paper stock, and it has been the practice not to calender it, for the reason that the
surface of the paper would thereby be rendered, too smooth. Such paper, therefore,
retains even in its finished state more or less of the chemicals used in its manufacture,
and this is especially the case with the poorer qualities of paper by reason of the thick-
ness thereof as compared with paper made from the best stock. The use of such paper
is thus rendered harmful for the purpose for which it is intended. Moreover, toilet-
paper made from the better qualities of stock is objectionable on account of its extreme
smoothness and because of the difficulty experienced in separating single sheets.from
a pack or bundle of the same, by reason of the adherence or clinging of the sheets to
each other.
By my invention, I overcome these difficulties and produce toilet-paper made from
the better kinds of stock, possessing qualities which make it especially advantageous
for the purpose for which it is chiefly intended.
According to my said invention I manufacture toilet-paper having an irregular or
roughened surface, that is to say, having indentations or depressions formed in its
surface so that the said toilet-paper, although made of the best quality of stock, will
nevertheless be free from the defects above named. My improved toilet-paper,
moreover, possesses other advantages hereinafter specified.
In the accompanying drawing
Figure 1 is a face view, drawn to an enlarged scale, of a piece of my improved
toilet-paper, and
Figure 2 is a section, also drawn to an enlarged scale, through one line of
indentations.
A is the paper; B, B, indicate the indentations or depressions which are formed in
it's surface during the process of manufacture and which impart the required roughness
to the paper.
In manufacturing my improved toilet-paper, I find the following method of
procedure convenient and advantageous, that is to say:-After the paper has been.
manufactured in the ordinary manner and before it leaves the machine, it is passed
between two rolls one of which is covered with felt or similar yielding substance, and
the other with wire-cloth, or the second roller is provided with projections on its
surface in lieu of the wire-cloth covering.
By subjecting the paper to this treatment, the fibres thereof are drawn or stretched,
and the toilet-paper produced with the desired indentations or depressions, which will
render it less smooth. The paper is, moreover, softened so that it is more agreeable
to use; furthermore the injurious chemicals employed in the preparation. or treatment
of the stock and which have been retained by the paper, are to a great extent squeezed
out by the rolls in the process of forming the said indentations.
•
It is necessary, in making my improved toilet-paper, to use the best stock or stock
of very superior quality in order to produce a paper that will be sufficiently tough to
receive and retain the indentations or depressions without rupture of the fibres.
Inferior qualities of paper would not be strong enough to be successfully treated in
this manner. The paper being, therefore, of necessity much stronger than that made
from inferior stock or materials, one sheet will answer the purpose of several of the
ordinary toilet-paper, and economy in use will thus be secured. The indented surface
of the paper also enables the sheets to be readily detached or removed from a pack or
bundle of the same singly one by one.
A furtlier advantage arising from the indented surface is that water will much more
easily dissolve and break or separate the paper into fragments than if the latter had
an even or smooth surface. Consequently the said paper is less liable.to.clog-drain-
pipes than papers of-the-thicker and cheaper qualities or than papers of the better
qualities having smooth surfaces.
The advantages of my improved toilet-paper may be enumerated as follows: The
paper is.softer and more agreeable to use than other toilet-papers, and retains to a
much less extent the harmful chemicals employed in the treatment of the stock.
Being produced in a manner which of necessity requires a strong class of paper-to

page_text: avoid rupture, it is therefore much stronger and more, economical in use; and the
indented surface enables the sheets to be readily separated singly from the pack or
bundle. Moreover owing to the indentations or depressions in the surface, water will
act upon it to better advantage to dissolve and break or separate it into fragments
than if its surface were smooth and even.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me by
my foreign correspondent I wish it understood that I claim :-
First. Toilet-paper provided with indentations or depressions substantially as
herein before described and for the purposes specified.
Second. The above described method of manufacturing my improved toilet-paper
by passing it between rolls one of which is provided with a covering of felt or similar
material and the other with a covering of wire-cloth or with projections, for the
purpose specified..
