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 :—
This invention has reference to rolls or bundles of toilet or wrapping paper
having lines of incisions for facilitating the severance of pieces or lengths from the
said rolls, such lines of incisions being in the same plane; and to apparatus for
forming the said incisions,
In the accompanying drawings:
Figure 1 is an end view of a paper roll or bundle containing my improvement.
Figure 2 is a top view of the same.
.
Figures 8 to 14 are views showing different means for retaining the lines of
incisions in the same plane.
Figures 15 to 21 are views of the apparatus for forming the said lines of
incisions.
Endeavours have been made to provide paper rolls which have all the lines of
perforations, at which pieces or lengths are separated from the roll, in the same
plane. Such rolls, however, have been worthless because attempts were made to
perforate the paper in the ordinary manner. It is found, however, impracticable
to perforate the paper in such a manner that all the lines of perforations are in the
same plane.
According to the first part of this invention the paper is incised instead of being
perforated, that is to say all its lines of weakness are formed by a series of
incisions instead of the ordinary form of perforations. In this way a roll of
paper can be produced having all its lines of weakness, or of separation, in the
same plane.
In figures 1 and 2, a is the paper roll or bundle; b, b are the lines of incisions
across the paper. As shewn in Figure 1 from c to c, all of such lines of incisions
are in the same plane.

page_text: The second part of my invention has for its object to retain all the lines of
incision in the same plane during the operation of severing the sheets, so that the
sheets can be conveniently separated one at a time.
In the drawings several rolls or bundles are shewn containing perforations or
incisions made through the roll of paper in the same vertical plane, and provided
with means by which the paper can be suspended against a wall or other vertical
surface, so that as one sheet is severed the end of the unsevered sheets will drop
down into position to be again caught hold of in order to sever another sheet.
Thus but one sheet at a time is taken from the roll. By means of this part of my
invention the roll will be kept constantly in the same position relatively to the line
of perforations, so that the dropping down of the next sheet after a sheet has been
withdrawn therefrom will leave it in position to be readily severed at the next
pull on the roll. Should the roll not have some device connected therewith to
prevent the lines of perforations from shifting, the roll would soon cease to act in
the above mentioned manner. I therefore accomplish this result by keeping in a
fixed position all of the lines of perforations in the roll.
As shewn in Figures 3, 4 and 5 the lines of perforations are kept in a fixed
position by means of tapes passed down through one or more sets of the perforations
or incisions.
2
In figures 6 and 7 these perforations are shewn as secured in a fixed relation by
means of a nail or wire passed down through one set of such perforations.
In Figure 8 the lines of perforations are shewn as being fixed by means of a
strip of cloth or paper glued to the edges of the perforations at the end of the roll.
A little glue or other adhesive material inserted at some point between each sheet
would also accomplish the same object.
Figures 9 and 10 shew a separate suspending device which may be passed down
through the centre set of incisions, or down through two sets if more than two are
used; in the latter case a rod is passed through the eyes of the suspending devices
(see Figure 13).
In Figures 11 and 12 is shewn a bale or hook having spring ends and an eye at
the top, the spring ends being adapted to be passed down through the perforations
or incisions.
Figure 14 shews a top view of a roll without any device passed down through
the perforations, but having mucilage lightly applied at any one point between its
sheets or at the end of the roll.
:
Various other methods of retaining these series of perforations could be used to
the same end as in the examples I have above given.
The third part of my invention which relates to means for perforating toilet
paper in the roll consists in the use of perforators of a lancet like form, by means
of which the series of slits are punched in the roll of paper through its whole
thickness. In connection with these means for perforating paper I use a solid
former on which the roll of paper is first placed before it is submitted to the
operation of the perforating lancets.
In the drawings:
Figure 15 is a front elevation of a machine by means of which the roll of paper
is perforated from its external periphery.
Figure 16 is an end view of such a machine.
Figure 17 is an end elevation of a machine by means of which the paper is
perforated from its internal periphery.
Figure 18 is a front view of this last mentioned machine.
Figure 19 is a longitudinal vertical section taken in the line ∞ ∞ of figure 17..
Figure 19 is a view of one of the lancets.
...
Figures 20 and 21 represent a machine having a gang of lancets but no core for
the roll, thereby dispensing with one element. The machine will be understood
from the description of that shown in figures 15 to 19 the lettering on the drawings.
being the same.

page_text: In figures 15 and 16 a is the base of the machine; b bare two standards into
which is inserted a core o carrying the roll of paper d to be perforated. is a link
connected at its lower end f to the bed plate or base a and having attached at its
upper end a lever g. This lever carries at the point h a gang of lancets i i which
move in ways jj of the standards b b.
This being a hand machine the pressing down of the lever g by the handle k will
force the gang of lancets i i down through the body of the roll of paper d.
เ
is a longitudinal groove in the core a through which the lancets pass after
having perforated the paper. The position of this groove / relatively to the gang
of lancets is determined by the slot m passing over a projection n of the standard b,
which keeps the groove perfectly vertical and in line with the gang of lancets.
o is a stripper, bolted at p p to the standards 6 6¹ and containing openings through
which the lancets pass.
In the machine shown in figures 17, 18 and 19 the base a is solid. The roll of
paper d is inserted in the machine with its core c by removing the link g, which is
one of two links q and q¹ attached to the lever gatii, the link g being hooked
on to the cross head after the paper has been so inserted through the standard b..
The core c is constructed with a long vertical slot in which the cross head is per-
mitted to move up and down, thus carrying the gang of 'lancets i i down through
the perforatious of a stripping plate s into the body of the roll of paper d. A long
groove t is made in the bed of the machine upon which the paper rests and into
which the points of the lancets pass after having completely perforated and incised
the body of the paper.
The operation of both of these machines is evident from this description of their
parts and need not here be detailed. It will be perceived that these are hand
machines but with the proper gearing, power can be applied thereto.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
First. A roll or bundle of toilet or wrapping paper provided with lines of
incisions, all of said lines being in the same plane, substantially as described.
Second. A roll or bundle of toilet or wrapping paper having all of its lines of
perforations in the same plane, combined with means for retaining them in such
position prior and during the operation of severing the sheets from such roll,
substantially as described.
Third. In machinery for perforating toilet or wrapping paper, the combination
of a gang of lancets, with a central core for the purpose of perforating the several
concentric layers of a roll of paper at one and the same operation, substantially as
set forth.
Fourth. In machinery for perforating toilet or wrapping paper a gang of lancets
for the purpose of perforating a roll of paper, substantially as set forth.
Fifth. In machinery for perforating toilet or wrapping paper a gang of lancets
for the purpose of perforating the several concentric layers of a roll of paper at one
operation.
