improvements in Insect Traps.
I JOHN DONATUS MCNALLY of Dale Street Liverpool in the County of
Lancaster, Accountant, do hereby declare the nature of this invention to be as
follows:-
The object is to provide a simple, efficient, and cheap trap for catching insects,
such as cockroaches, beetles, crickets, and the like, such traps having the advantages
of being easily emptied and kept clean.
A trap under my invention consists of a chamber having inclined walls and an
aperture or apertures for the entrance of the insects, such chamber being made in
two parts separable from each other. The rising walls are made rough externally
so as to form a foothold for the insects, whilst internally the walls are smooth
and overhanging.
A convenient construction of trap has the chamber in the form of a truncated
cone having an aperture above, the inside being smooth, whilst the outside is clothed
with sand or emery.
A sliding or hinged bottom or equivalent discharge door is provided.
I JOHN DONATUS MCNALLY of Dale Street Liverpool, in the County of
Lancaster, Accountant, 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 object is to provide a simple, efficient, and cheap trap for catching insects
such as cockroaches, beetles, crickets, and the like, such traps having the advantages
of being easily emptied and kept clean.
A trap under my invention consists of a chamber having inclined walls and an
aperture or apertures for the entrance of the insects, such chambers being made in
two parts separable from each other. The inclined rising walls are made rough
externally so as to form a foothold for the insects whilst internally the said walls
are smooth and overhanging.
Fig. 1 is a perspective view of a trap under my invention in the form of a
truncated cone. a are the inclined walls roughened externally and smooth
internally. b are apertures through which insects enter the chamber formed by the
inclined walls a and sliding bottom c. The walls a are formed with overhanging
lips d to facilitate entry of insects into the trap and prevent their escape there-
from. The bottom c is made with upturned edges e which grip the walls a and
hold the parts together. The trap may be made with the lateral apertures or the
central aperture only. The two parts may be each stamped out of one piece of
metal.

a walls. aperture. c bottom. d overhanging lips. e upturned edges.
In Fig. 1 the bottom is shown closed. In Fig. 2 the bottom is shown partly
withdrawn to allow of insects being removed from the trap.
A great advantage of traps constructed in accordance with my invention is that
when the parts are separate the top portions can be packed one within the other so
as to occupy small space and facilitate transport.
It will be obvious that the upper portions may be made hexagonal, octagonal,
or of other shape in plan instead of round or square as shown, and that catches may
be used to hold the bottoms in closed position.
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 :-
First. An insect trap constructed in two pieces substantially as set forth.
Second. The combination of walls a having an aperture or apertures b, and
overhanging lips d with a bottom c having upturned edges e.
