PROVISIONAL SPECIFICATION.
Improvements in Wrappers for Transmitting Periodicals or the like.
I, PERCY JOIN OGLE, of 4 Bishopsgate Street Within the City of London,
Engineer do hereby declare the nature of my invention to be as follows:-
My invention relates to wrappers used to contain periodicals, newspapers, music
sheets, and the like for transmission through the post or by other means, and has
for its object the provision of means whereby the inconvenience of the present
system of wrappers is entirely avoided.
The usual method of preparing periodicals, newspapers etc. for transmission by
post, or otherwise, is to roll the paper or pamphlett into a cylindrical form, roll and
tightly surround it by an embracing wrapper which is usually fastened by being
gummed to itself. The paper or periodical uncoils itself until restrained by the
wrapper, and the parcel thus formed is securely held intact, but great difficulty is
experienced in stripping the wrapper from the matter that it contains, as it cannot
be torn right across from side to side owing to the tightness with which the wrapper
embraces the roll, and also by reason of the curved shape of the wrapper, the
tendency of two lines of fracture which may be started parallel to one another would
be to converge together until they merge into a single line of fracture; further, that
the periodical or other matter enclosed is often torn in stripping the enclosing
wrapper from it.
My invention entirely overcomes these difficulties and consists in providing the
wrapper with two or more lines of perforations, cuts, slits, or other means by which
the material can be locally weakened in the manner hereinafter described. The
lines of weakness run from one side of the wrapper to the other, in any direction or
course which may be thought desirable.
1 may form a tab at one end of the strip between the lines of weakness
with which the strip may be pulled to detach the strip from the rest of the
wrapper.
When this tab or the end of the strip is pulled with sufficient force the
wrapper is torn or fractured through the lines of weakness and the continuity
of the wrapper in its circular or embracing form is destroyed and the contents are
released.
As the tendency of the two or more lines of fracture is to converge towards
each other in the particular circumstance set forth I use a certain form and
disposition of perforations, cuts, or slits which is as follows:-
The perforations are formed by simply cutting slits in the material of the wrapper.
These slits are disposed in two lines preferably parallel to one another, and the slits
of each line are disposed parallel to one another and at an angle to the direction of
the line, the slits preferably over-lapping one another in a line at right-angles to the
line of the slits. The slits of each line are disposed at the opposite angle of the
slits of the other line, and the end from which the strip is first torn is that end
towards which the angular slits on each side converge.
When now the strip is torn from the wrapper, the outward direction of the slits
on each side counteracts the inward tendency of the fracture through the
imperforated material, is as much as such inward direction is stopped by the
fracture, running into the next slit which points outwards, and thus the lines
of separation are of a zigzag form.

I PERCY JOHN OGLE of 4 Bishopsgate Street Within, in the City of London
Engineer, 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 has for its object to provide a wrapper more especially intended
for transmitting purposes for enclosing for instance periodicals or the like which it
is desired shall be rolled for transmission through the post or otherwise. It has
hitherto been the practice to roll the periodical or the like (which I will refer to
as the enclosure) into a cylindrical form and encircle it by the wrapper which is
then secured by gum at its edge. The tendency of the enclosure being to unroll
itself the wrapper and enclosure are securely held together but great difficulty is
experienced in removing the wrapper, as owing to the tightness with which the
wrapper embraces the roll and owing to the cylindrical shape thereof if it be
attempted to tear the wrapper from end to end thereof the two lines of fracture
which are made at the commencement in such an attempt converge and meet and
the result is that only a comparatively small wedge shaped piece of the wrapper is
removed. These lines which so converge I will call the lines of irregular fracture.
The attempt to remove the ordinary wrapper moreover frequently results in the
tearing of the enclosure. The object of my invention is to overcome these difficulties
and consists in perforating or penetrating or locally weakening that part of the
wrapper which comes outermost when it is rolled around its enclosure with
preferably two lines of cuts, slits, slots or their equivalents (I will refer to them as
slits) so arranged that a narrow strip is constituted which can be readily removed
by tearing from end to end of the wrapper thus opening it. The slits are so
disposed relatively to each other that the aforesaid lines of irregular fracture
which occur after the ends of the respective slits are reached in tearing will run
into the next of the slits and so on throughout the length of the series of slits.
Figure 1 of the accompanying drawing represents a wrapper provided with lines
of slits according to my invention.
The slits a of each line are shewn at the angles and disposition relatively to each
other that I find best in practice. By the dotted lines at b in Figure 1 I have
indicated the lines of irregular fracture tending in each case inwards when the
wrapper is wound round the roll which it encloses and the strip is torn away. The
arrow represents the direction in which the strip is to be torn. It will be seen that
when the end of each slit is reached the severance is in the said lines of irregular
fracture until they run into the next slits and so on throughout the length of the
strip the disposition of the slits constantly counteracting the inward tendency of
the lines of irregular fracture.
Figure 2 shews an enclosure with a wrapper around it and the strip in course of
being torn off.
When the wrapper is around a cylinder or roll the tendency of the lines of
irregular fracture is always inwards. If it be desired to provide a wrapper which
will also be suitable for flat packages or folded articles I may duplicate the slits
of each series as shown in Figure 3 one member (a) pointing outwards, and the
other (a) inwards, as with a flat wrapper the lines of irregular fracture may tend
to take either an inward or an outward course. The slits a counteract the inward
tendency of the lines of irregular fracture whilst the slits a² counteract the outward
tendency of the lines of irregular fracture. I have shewn in each case at the end
from which the severance is to be comnienced a tab d made by two slits or cut away
parts at d² d² by which the severance can be properly started.

page_text: I do not limit myself to the shape of slits shewn as they may be of other form
for instance holes of any shape provided that the lines of irregular fracture are
intercepted by the slits holes or their equivalents as described.
As it is generally not allowable to place advertisements outside postal wrappers
and as in separating the strip the back thereof is exposed I may utilize the back
of this strip to print advertisements upon.
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 :-
:-
A wrapper having slits cuts perforations slots or the like disposed substantially
as hereinbefore described and illustrated for the purpose of enabling a strip to be
removed therefrom by tearing in unfastening or removing the said wrapper.
