A NEW OR IMPROVED MEANS FOR CATCHING BEETLES, COCKROACHES, AND OTHER INSECTS."
Year: 1880

page_text: LETTERS PATENT to Alfred Nash, of Canterbury, in the County of Kent, for
an Invention of "A NEW OR IMPROVED MEANS FOR CATCHING BEETLES,
COCKROACHES, AND OTHER INSECTS."
PROVISIONAL SPECIFICATION left by the said Alfred Nash at the Offic
of the Commissioners of Patents on the 8th December 1880.
ALFRED NASH, of Canterbury, in the County of Kent. "A NEW OR IMPROVED
MEANS FOR CATCHING BEETLES, COCKROACHES, AND OTHER INSECTS."
My Invention has for its object the catching or securing of beetles, cockroaches,
and other domestic insect pests in a more effectual manner than has hitherto been
attainable, and consists essentially in the construction and use of a trap coated with
the composition, all as hereinafter described.
I make a base plate of square, circular, oval, or other convenient shape, and of
wood or other suitable material, such base plate being by preference bevelled or
chamfered at its outer upper edges, and provided at its upper side with two, three,
or more strips or pieces of wood, in order that when the traps are packed for
transmission the composition hereinafter mentioned may remain free from contact
with other surfaces, and therefore uninjured.
I coat the upper surface of the plate, with the exception of the strips herein-
before mentioned, with a composition of oil or oils and resin or resinous substances
in or about the following proportions, namely:-Three parts of resin and one of
the oil or oils. By preference I use linseed oil and sweet oils in equal quantities,
and they are mixed or worked up with the resin so as to form a paste or coating,
which attracts the insects, and to which they adhere until they die or are
destroyed.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Alfred Nash in the Great Seal Patent Office on the 7th June
1881.
ALFRED NASH, of Canterbury, in the County of Kent.
"A NEW OR IMPROVED
MEANS FOR CATCHING BEETLES, COCKROACHES, AND OTHER INSECTS."
I. My Invention has for its object the catching or securing of beetles, cock-
roaches, and domestic insect pests in a more effectual manner than has hitherto

with the composition, all as hereinafter described.
II. I make a base plate of square, circular, oval, or other convenient shape, and
of wood or other suitable material, such base plate being by preference rabbeted, or
bevelled, or chamfered at its outer upper edges, and provided at its upper side with
two, three, or more strips or pieces of wood, in order that when the traps are packed
for transmission the composition hereinafter mentioned may remain free from contact
with other surfaces, and therefore uninjured.
III. I coat the upper surface of the plate, with the exception of the strips herein-
before mentioned, with a composition of oil or oils and resin or resinous substances
in or about the following proportions, namely:-Three parts of resin and one of
the oil or oils. By preference I use linseed oil and sweet oil in equal quantities,
and they are mixed or worked up with the resin so as to form a paste or coating,
which attracts the insects, and to which they adhere until destroyed.
IV. Although I do not confine myself to the exact shape of the base plates for
carrying the coating of composition on their upper surface, I find it convenient in
practice to make them of the form of a parallelogram, and of thin wood, and I
rabbet these parallelograms at their edges in such manner that they resemble
an upper parallelogram superimposed upon a lower one. The composition is
contained within a vessel, and kept heated by a gas, oil, spirit, or other stove
placed beneath the said vessel.
A distributing plate of metal or other material within the said vessel is operated
or moved upwards and downwards by a lever, so that it can be brought to the
surface with the requisite quantity of the composition. The parallelogram is then
placed thereupon and receives the composition on its upper surface (inverted for
that purpose), and the rabbeted edge prevents the smearing or running over of the
composition, and ensures cleanliness for packing. The distributing plate is returned
to its original position by a counterweight attached to the lever. The strips or
pieces for preventing contact between the traps when packed (by preference squares
of about one eighth of an inch) are then placed upon the coated surface, say, one at
each corner of the parallelogram, and one centrally, and the traps are ready for
packing.
Having now particularly described the nature of my said Invention, and the
manner in which the same is to be carried into effect, I wish it to be distinctly
understood that what I claim and desire to secure by the hereinbefore in part
recited Letters Patent is,-
Firstly. The adhesive composition.
Secondly. The base plate for receiving same.
Thirdly. The rabbeted, or bevelled, or chamfered edges of base plate.
Fourthly. The strips, squares, or pieces, all as and for the purposes described in
this Specification, and also the combination of the whole of the features, so as to
form an effective trap convenient for packing and transportation.
In witness whereof, I, the said Alfred Nash, have hereunto set my hand
and seal, this First day of June, in the year of our Lord One thousand
eight hundred and eighty one.
