Improvements in Insect Traps.
A communication from EDUARD KAVALIER, of Neu-Sazava, Bohemia, in the
Empire of Austria, Glass manufacturer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. do hereby declare the nature of this invention to be as follows
The object of the present invention is an insect trap mostly made of glass, con-
sisting in the main-
1. Of a partially or entirely rough ascending part over which the insect can easily
climb, and secondly, directly connected with this rough climbing surface, one or more
smooth sliding surfaces inclined towards the interior of the vessel, giving the insect
no hold, so that it falls into the interior of the apparatus, out of which it cannot
escape. The sliding surface is funnel-shaped and has smooth surfaces inclining
inwards and downwards. This sliding surface is either suspended loosely in the
apparatus and can be easily removed and changed or it may be in one piece, as part
of the apparatus. In one construction the insect trap is made all of one piece in the
form of a cone-shaped vessel, the upper rim of which is bent conically inwards in the
form of a funnel. The surface of this funnel is smooth and serves as a slide or shoot
for the insect attracted from without, after it has travelled over the outer surface of
the cone-shaped body. The insect slides or drops into the interior of vessel in which
is placed some bait mostly consisting of some substance or solution for which
particular insects have a predilection.
The roughening of the outer surface of the cone-shaped body can be effected by
coating or covering it with some material that presents a rough surface or in any other
convenient manner.
Any number of funnel-shaped sliding surfaces leading into the interior of the.
vessel may be provided in the inclined surface of the said vessel. In some of the
traps constructed according to this invention there are merely openings (without
inclined shoots) on the outer surface of the vessel which under such arrangement is
constructed so as to present a portion of the interior surface of the body as the
sliding surface or so as not to present any surface between the openings and floor of
the vessel.
In another arrangement the trap is formed with a smooth inclined sided trough with
holes through which the insects fall after they have slipped over the smooth surfaces of
the trough.
For purposes of cleaning or emptying these insect traps an opening may be
provided or a somewhat wide slit can be cut out in the funnel which will allow of the
vessel being emptied. Some of the arrangements open above as in the case of bottles
into a neck and through this the vessels can be emptied. If desired this neck can be
closed with a plug. Traps with the beforementioned loose funnel can be emptied
simply by lifting up the funnel and turning out the contents of vessel.
These traps are preferably blown round, oval, or square and made of glass smooth
or pressed.

Improvements in Insect Traps.
A communication from Eḍuard KAVALIER, of Neu Sazava, Bohemia, in the
Empire of Austria, Glass manufacturer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.
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:
The present invention relates to insect traps préferably made of glass and
comprising ;
1. an entirely rough, entirely transparent or partially rough and partially
transparent surface over which the insect can easily ascend and
2. in this surface or adjoining it one or more shoots or funnels through which
the insect falls into the interior of the trap from whence it cannot escape.
If funnels are used, the walls of these funnels are perfectly smooth so as to offer
no hold to the falling insect and they are either made with the whole apparatus in one
piece or are merely suspended in suitable openings,
.
In the accompanying drawings:
-
Fig. 1 represents an insect trap in which A is the body of glass with partially.
transparent surface a and an opening o.
Fig. 2 represents a similar trap with suspended funnel t.
Fig. 3 represents another form of trap in which the openings o (four being shown)
are in the inclined sides of the apparatus. The neck c of the apparatus through.|
which the contents of the latter can be emptied is closed with a stopper S.
Fig. represents a similar apparatus with funnels the whole being made in one
piece.
Fig. 5 represents an insect trap with vertical sides in which are formed the
openings which the insects reach by ascending bars s which are placed against the
openings o.
It is preferable to construct the traps with a partially transparent surface as it has
been found in practice that the trap is more effective when the insect not only can
smell but also see the liquid contained therein.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent I declare that what I claim is.;-
1. An insect trap such as A made of wholly or partially transparent material (preferably
glass) having a partially roughened surface over which the insects ascend to an
opening o situated at the top of the trap and through which the insects fall into the
interior of the trap substantially as described and illustrated in figure 1 of the
accompanying drawings.
2. In an insect trap as claimed in the foregoing clause the arrangement of a smooth
walled shoot or funnel such as t suspended in the opening o substantially as described
and illustrated in figure 2 of the accompanying drawings.
3. The arrangement of one or more openings formed in the inclined sides of
the conical apparatus substantially as described and illustrated in figure 3 of the
accompanying drawings.
4. The arrangement of smooth walled shoots or funnels such as b instead of the
simple openings, o in the sides of the conical apparatus substantially as described and
illustrated in figure 4 of the accompanying drawings.
5. Au insect trap with steep or vertical sides formed with openings o at or near
the top of these sides substantially as described and illustrated in figure 5 of the
accompanying drawings.

page_text: 6. In an insect trap the combination of rough and transparent surfaces the former
for the purpose of facilitating the ascent of the insects the latter for permitting the
insects to see the fluid contained in the trap. -
