PROVISIONAL SPECIFICATION.
Improvements in Fly Papers.
I, WALTER WRAY HOPKINSON, of 53 St. Sepulchre Gate, in the Township of
Doncaster in the County of York, Chemists' Assistant do hereby declare the
nature of this invention to be as follows:
My invention relates to the improved construction of papers for catching and
killing flies and other insects.
The objects of my invention are to coat these papers with a sticky substance,
which while being attractive is also of a poisonous nature to insects, and further to
fold and close the papers in such a manner that it is impossible for the sticky
substance to exude therefrom or to dry up before the papers are opened for use.
In the manufacture of my improved papers, I employ sheets of any suitable kind
of non-porous paper and coat the sheet on one side only with a sticky composition
of a nature that will attract insects and is at the same time poisonous to them, but
not to human beings or animals. The composition is not spread over the whole
surface, but a clear margin is left all round the edge so that the paper can be con-
veniently handled.
The said composition consists of the following ingredients mixed in about the
following proportions, viz.
2 lbs. of birdlime.
1 lb. of treacle.
oz: of quassia.
The poisonous nature of the composition shortens the struggles and sufferings of
the insects, which become attached to it.
After the paper is coated it is folded down the centre with the sticky sides of the
two halves coming together.
Two diagonal folds are then made in the doubled paper, one over the other so
that the completed shape is triangular, and all the free edges are brought together
on one side of the triangle. A folded gummed strip of paper is then fastened over
these edges, and the inside or coated part of the paper is thus hermetically sealed
from contact with the atmosphere, so that the composition cannot dry, nor can it
exude no matter in what position the papers may be placed or stored.
To open the paper it is only necessary to cut through the gummed strip aforesaid
when it can be readily unfolded.
Advertisements or other printed matter may be placed on the papers in any
lesired part.
I am aware that fly papers coated with a sticky composition have heretofore
been folded in various ways for storage and transport, but such papers have not
been hermetically closed, and the composition has been liable to dry and exude
herefrom, particularly when stored in certain positions and in warm weather.
Dated this 28th day of March 1892.

As under certain circumstances, the above composition has, a tendency, to become
hard by keeping, I sometimes add a proportion of castor, oil which enables it to keep
moist, for any length of time..
Fig. 1 represents a sheet of paper of the kind above described, the shaded portion

margin A'all round.

The paper is folded in two through the dotted line B.B, with the sticky surface
inside and represents, the appearance shewn in Fig. 2, it is then folded through the
diagonal line C C and represents the appearance shewn in Fig. 3.
The final fold is through the dotted, line, D D, leaving the paper of triangular
form, as shewn in Fig. 4, with all the four clear outside edges A of the paper
together on one side. A folded gummed strip of paper E, Fig. 5, is then fa
is then fastened
over the said edges, completing the, operation, as shewn in Fig. 6.
By this method of construction the inside, or coated surface of the paper is
hermetically, sealed from contact with the atmosphere, so, that the, composition
cannot dry, nor can it exude, no matter in what position the papers may be placed"
or stored.
To open the paper it is only necessary to cut through the folded edge F of the
gummed strip E when the said paper can be readily opened out.
Advertisements or other printed matter may be placed on the paper in any
desired part.
I am aware that fly papers coated with a sticky composition have heretofore been
folded in various ways for storage and transport, but such papers have not been
hermetically closed, and the composition has been liable to dry and exude there-
from, particularly when stored in certain positions, and in warm weather.

page_text: 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 :-
:-
1. In the construction of a fly paper, a sheet of suitable non-porous paper, coating
said paper on one said only with a sticky composition attractive and poisonous to
insects, said coating not extending to the edges of the paper but leaving a clear
margin all round, then folding said paper so that said composition is inside and all
said clear edges come together on one edge, and finally enclosing said edges by a
folded gummed strip of paper.
2. An improved fly paper, consisting of a sheet of suitable non-porous paper,
coated on one side only with a sticky composition, attractive and poisonous to
insects, said coating leaving a clear margin A all round, then folding said paper
successively along the lines B B, C C, and D D into a triangular form with all the
margins A on one side, and finally covering said margins with a folded gummed
strip E, substantially as described.
3. An improved fly paper, consisting of a sheet of suitable non-porous paper,
coated on one side only with a sticky composition attractive and poisonous to
insects, said composition formed of birdlime, treacle and quassia in the proportions
herein stated and said paper folded in the manner set forth.
