PROVISIONAL SPECIFICATION.
An Improved Fly Paper.
I, CHARLES GLEN of 799 Garscube Road, Glasgow, Lanarkshire, Manu-
facturing Chemist do hereby declare the nature of this invention to be as
follows:-
This, my invention relates to a new and improved fly paper of a sticky nature
and the novelty of the said invention consists in the manner of sealing and binding
the said fly papers in order that they may be conveniently packed for transmission,
export etc., and further that they may be conveniently handled without sticking to
the hands.
Hitherto, when sticky fly papers have been packed closely together, the sticky
material, of which the fly papers are partly composed, exuded from the edges
thereof and coming in contact with the other papers immediately above and below
made the whole a sticky mass objectional to handle and awkward to unpack and
separate.
Or the sticky fly papers have been folded in the centre and also folded at
each or any of the remaining three sides, which causes the paper in the centre
to be liable to crack and the consequent exudation of the sticky substance, making
them objectional to handle; the folds on the remaining three sides being a laborious
and expensive operation.
Now by the use of my invention the above referred to objections are entirely
overcome in a neat, simple, and efficacious manner, hereinafter described reference
being had to the accompanying drawings and the figures and letters marked
thereon.
Fig. 1 represents the fly paper open.
Fig. 2 shows the fly paper closed, and ready for packing.
Fig. 3 is an end view of the fly paper closed and shewing the two side binders.
Fig. 4 represents two sheets of paper used in the manufacture.
Fig. 5 represents one of the binders.
Fig. 6 is an end view of one of the binders.
In the manufacture of my improved fly papers, two sheets of paper are used, as
shown in Fig. 4, which are oiled or otherwise made waterproof or greaseproof.
These two sheets are sealed or pasted together at the point A, as shown in Fig. 1,
so as to make one large fly paper to open in book form.
This fly paper is coated on the one side with a sticky or tacky material B in
the usual way. This said sticky material, however, is not coated to the extreme
edges but to within a small margin thereof, allowing the said sticky mass to spread
to the edges of its own accord.
It is not desirable, however, that the sticky substance should go to the edges of
the fly paper, and to prevent its getting there, pressure is brought to bear on the
three sides C, as shown in Fig. 2, by means of binders, hereinafter described, and,
if desirable, also on the top of the join A, thereby checking the progress of the
sticky material and causing it to remain in the centre of the closed fly paper. No
folds whatever appear in this fly paper.
Fig. 5 represents one of the binders which may be made in several forms, but
by preference I use a piece of tin-plate about two inches broad and of a suitable
length. This is bent longitudinally to the required form.
These binders are placed on the sides C, as shewn in Fig. 2, and compressed
thereon in order to give the required pressure.
The economy of this expedient consists in the application of the binders to any

An Improved Fly Paper.
1, CHARLES GLEN of 799 Garscube Road, Glasgow, Lanarkshire N.B., Manu-
facturing Chemist 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, my invention relates to a new and improved fly paper of a sticky nature,
and the novelty of the said invention consists in the manner of sealing and binding
the said fly papers in order that they may be conveniently packed for transmission,
export &c.; and further that they may be conveniently handled without sticking to
the hands.
Hitherto, when sticky fly papers have been packed closely together, the sticky
material of which the fly papers are partly composed exuded from the edges
thereof and coming in contact with the other papers immediately above and below;
made the whole a sticky mass objectional to handle and awkward to unpack and
separate.
Or, the sticky fly papers have been folded in the centre and also folded at each
or any of the remaining three sides, which causes the paper in the centre to be
liable to crack and the consequent exudation of the sticky substance making them
objectional to handle; the folds on the remaining three sides being a laborious &
expensive operation.
Now, by the use of my invention the above referred to objections are entirely
overcome, in a neat, simple and efficacious manner, hereinafter described, reference
being had to the drawings left with the Provisional Specification and the figures
and letters marked thereon.
Figure 1 represents the fly paper open ready for use.
Figure 2 shows the fly paper closed, ready for packing.
Figure 3 is an end view of the fly paper closed and shewing the two side
binders.
In the manufacture of my improved fly papers, two sheets of paper are used
which are oiled or otherwise made waterproof or greaseproof.
Fig. 4 represents the two sheets.
These two sheets are sealed or pasted together at the point A as shewn in Fig. 1,
so as to make one fly paper to open in book form. This fly paper is coated on the
one side with a sticky or tacky material B, in the usual way. This said sticky
material, however, is not coated to the very edges of the paper, but to within a
small margin thereof, allowing the said sticky mass to spread to the edges of its
own gravity. It is not desirable, however, that the sticky substance should go to
the edges, & to prevent its getting there, pressure is brought to bear on the three
sides C, by means of binders, hereinafter described, as shewn in Fig. 2, and if
desirable also on the join A, thereby checking the progress of the sticky material
and causing it to remain in the centre of the paper.
Fig. 5, represents one of the binders, which may be made in several forms, but
by preference I use a piece of tin plate bent to a suitable form. These are placed
on the sides C, and compressed thereon in order to give the required pressure.
The economy of this expedient consists in the application of the binders to a
number of fly papers at one time instead of treating each fly paper separately
thereby saving considerable expense. My fly paper may also, if so desired be
sealed on each or any of the sides C & the binders placed above these to form
double security & protection.

page_text: Having now particularly described my said invention and in what manner the
same is to be performed I declare that what I claim is
Sealing each or any of the sides of the fly paper & binding the same, substantially
as & for the purposes hereinbefore set forth.
Dated this 25th day of Anril 1892.
