APPARATUS FOR THE DESTRUCTION OF FLIES AND OTHER INSECTS," to be as

Instead of the various prepared papers containing poisonous matters which
are dangerous in their use and application, I make a vase of glass or other

page_text: material in which I put a quantity of vinegar or other matter serving tho
purpose which will suffocate or intoxicate the insects. On the rim of the
vase I fix a flat metal ring, to distend a circular picce of white paper with a
-hole in the centre about the eighth of an inch in diameter. I paint around this
hole on the under surface of the paper resting within the vase to about the
circumference of a shilling, with honey or other matter agreable and attractive
to flies or insects, so that they will enter by the said hole, and in a very short
time will fall in the liquor under the influence of the smell thereof. Under
the vase I fix a strainer to separate the dead insects from the liquor whenever
necessary.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Walter Hart in the Great Scal Patent Office on

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN

agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use, -
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for. "AN
APPARATUS FOR THE DESTRUCTION OF FLIES AND OTHER INSECTS," a communication
from abroad by Frederick Barnett, residing at Paris, in the Empire of France,
upon the condition (amongst others, that I, the said John Walter Hart, my
executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office

page_text: within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John Walter Hart, do hereby declare
the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
Instead of the various prepared papers containing poisonous matters which
are dangerous in their use and application, I make a vase of glass or other
suitable material of any desired shape, in which I put a quantity of vinegar,
ale, or other matter which will suffocate or intoxicate the insects. On the
rim of the vase I place a ring having a ledge, on which is distended a piece of
paper or other suitable material with one or more holes of about the eighth of
an inch in diameter. Around the hole or holes on the under surface of the paper
or material I paint honey or other matter agreable and attractive to the flies
or insects, so that they may be induced to pass through the said hole or holes
into the interior of the vase, where in a short time they will become intoxicated
or suffocated and fall in the liquor. I furnish the vase holder with a
strainer for the purpose of separating the dead insects from the liquor when
necessary.
In order that the said Invention may be more clearly understood, I have
given reference to the accompanying Sheet of Drawings, in which Fig. 1 is an
external elevation of the improved apparatus; Fig. 2, a section of the same;
and Fig. 3, a plan of the ring and distended paper or material.
a represents the vase, into which is poured the ale, vinegar, or other liquor;
b, the ring, having an edge which fits easily on the rim of the vase, and also
a ledge on which is distended the paper or other material c, having holes or
perforations d, so that the insects may pass through them to the under side.
Or, instead of a ring to distend the material, I make the whole of the top or
lid of perforated metal. The vase is furnished with a foot e, which is placed
in a pedestal or holder f, the interior of which is funnel-shaped and fitted with
a strainer g, forming the base of the funnel when the pedestal is reversed,
thus affording the means of separating the insects from the liquor into which
they have fallen.
Having thus fully described the nature of the said Invention, as communi-
cated to me by the said Frederick Barnett, and the manner in which the
same is to be performed, I desire it to be distinctly understood that I do not
confine myself to precise details herein set forth, as such may be varied or
modified without departing from the principle thereof; but I claim the

page_text: arrangement and construction of an apparatus for destroying insects as herein
described and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said John Walter Hart, have hereunto set my
hand, and seal, this Sixteenth day of September, in the year of our
Lord One thousand eight hundred and fifty-nine.
Signed, sealed, and delivered, by the
within-named John Walter Hart,
in presence of
