Improved Sticky Fly Papers and New Methods of Closing the same.
I, DAVID DONALDSON BUCHAN of Gardyne Street Friockheim Forfarshire
Chemist and Druggist 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 a new method of manufacturing fly papers of a sticky
nature and the novelties consist of firstly, adding to a suitable sticky composition,
composed of colophonium, gum thus, linseed oil, glycerine and turpentine; flavouring
essential oils such as citronella, cassia, cloves, lemon or other odorous essential oils
which will make the papers more attractive to flies and other winged insects, then
spreading this perfumed sticky composition on stout stiff paper and secondly a new
method of closing the fly papers so as to prevent leakage of the perfumed sticky
composition by spreading round three sides of one half of the paper liquid gum or
glue and folding over on this the remaining half of the paper so that the edges of
the paper are held together by the gum or glue or alternatively, to fold the papers
across the centre and then gum or glue over the three open edges strips of paper and
double them over so as to adhere over both sides of the folded fly paper and
thereby prevent leakage of the perfumed sticky composition.
In order that my invention may be more clearly understood I will refer to the
accompanying drawings.
Fig. 1 represents a single paper the squares showing the perfumed sticky
composition, the margins A are covered with a coating of liquid gum or glue and
the other half of the paper, B, is folded over at the line C. D. and compressed
round the margins A or alternatively as on Fig. 2 to gum or glue strips of paper
represented at E, F and G, on to the outside of the fly paper leaving a projecting
margin then folding the fly paper at the line C. D, and doubling over the projecting
margins of the strips of paper and fastening them down to the fly paper with gum
or glue and thereby prevent leakage of the perfumed sticky composition.
Fig. 3 shows the section of a folded fly paper with the strips of paper E and G
folded over and fastened to the fly paper.
The perfumed sticky composition to be made as follows. Colophonium,
32 parts, (thirty two); gum thus, thirty two parts; linseed oil, forty eight parts;
glycerine, two parts; turpentine, eight parts; and a flavouring essential oil as
hereinbefore mentioned, one part. First boil thirty two parts of the linseed oil
until it becomes thick and stringy then add the colophonium, gum thus, glycerine,
turpentine and the remaining sixteen parts of the linseed oil and continue the heat
until all are melted, then withdraw from the source of heat and when beginning to
cool add one part of a flavouring essential oil to perfume as hereinbefore
mentioned.
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 fly paper spread with a perfumed sticky composition and closed by having the
three open edges of the folded paper gummed or glued together or alternatively to
gum or glue strips of paper over the three open edges and thereby prevent leakage
of the perfumed sticky composition.
