PROVISIONAL SPECIFICATION.
A New or Improved Insect or Vermin Trap.
I, CHARLES CAMPBELL, of 225, Prince Regents Lane, Custom House, London,
Gentleman, do hereby declare the nature of this invention to be as follows:
-
My invention relates to a new or improved insect or vermin trap, the object
being to provide a trap of extremely simple construction which shall, efficiently
fulfil the object in view, while it can be readily taken to pieces for cleaning pur-
Loses, emptying etc., and is suitable for trapping insects and vermin of various
kinds, such for instance as cockroaches, flies, wasps and the like.
In carrying my invention into practical effect, I provide a suitable receptacle
preferably rectangular in shape and furnished with a readily removable
glass lid or cover, the said receptacle having suitable openings at the sides com-
prising inwardly leading passages the sides of which converge and are furnished
at their extreme end with a small and light V-shaped flap which may be made of
tale, or other suitable material, so as to be readily raised by the beetle or insect
and thus allow of its entrance into the trap, at the same time preventing its exit
therefrom.
The aforesaid. inwardly leading passages may be formed of perforated zinc or
other suitable material while the floor of same may be roughened or constructed
of wood or other suitable material so as to form a foothold for the insects entering
same.

I, CHARLES CAMPBELL, of 225, Prince Regents Lane, Custom House, London,
Gentleman, 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 or improved insect or vermin trap, the object
being to provide a trap of extremely simple construction that shall efficiently.
fulfil all the requirements of such a trap, while it can be readily taken to pieces;
for cleaning purposes, emptying, etc., and is suitable for trapping insects and
veimun of various kinds, such for instance as cockroaches, flies, wasps, and the like.

page_text: In carrying my invention into practical effect, I provide a suitable receptacle
preferably rectangular in shape and furnished with a readily removable glass lid
or cover, the said receptacle having suitable openings at the sides or ends com-
prising inwardly leading passages the sides of which converge and are furnished
at their extreme ends with small light flaps which may be made of talc, celluloid,
or of aluminium, or of other suitable metal or material, arranged in such a manner
as to be readily raised by the beetle or other insect and thus allow of its entering
the tap, at the same time preventing its exit therefrom.
The aforesaid inwardly leading passages may be formed of perforated zinc or
other suitable material, while the floor of same may be roughened or constructed
of wood or other suitable material so as to form a foothold for the insects entering
same.
In order that my invention may be more fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which Fig. 1 is
a plan of my improved insect or vermin trap and Fig. 2 a cross section of same.
Fig. 3 is a plan of a slightly modified form of trap, and Fig. 4 a cross section of
same.
My improved insect or vermin trap comprises a suitable receptacle a preferably
rectangular in shape the edges of which are bene over as at b to support the glass
cover or lid c (Fig. 2), the parts d being bent over the top of the glass to secure
it at that end and to prevent it being pushed off, while at the other end I arrange a
wire catch d¹ for further retaining it in position, and a wire handle f is provided
to enable the trap to be easily lifted about.
At each end of the trap suitable openings and inwardly leading covered passages
P, P, are formed, the sides of which converge as shown Figs. 1 and 2, the ex-
treme end of each passage being covered with a light flap y as shown and in such
a manner as to allow of its being readily raised by the beetle or insect when entering
same, while it prevents its exit therefrom.
As a modified form of my invention I may instead of furnishing the ends of the
inwardly converging passages with a flap such as g (Figs. 1 and 2), continue the
sides of such passages until they meet or approximately meet at a point, the sides
or a portion of the sides h (Figs. 3 and 4) being in this case formed of thin flexible
material, in such a manner as to be readily displaced by the insect or the like
when entering the trap and to automatically close together after the insect or the
like has passed through. In this case the sides of the passage may be formed of
a height to correspond with that of the trap and a cover to the said passage is
therefore unnecessary.
In addition to the use of my improved trap for catching ordinary insects or
vermin, the modified form illustrated in Figs. 3 and 4 is also suitable for the
trapping of water insects, fish, and the like, in which case any suitable bait may
be placed within the trap and the trap immersed in the water of a stream, pond,
or the like, the trap in this case operating in a similar manner as when employed
for trapping insects vermin and the like.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The new or improved insect or vermin trap, comprising a preferably rect-
angular case or frame such as a, formed with inwardly leading and converging
passages such as p, p, each furnished at its extremity with a light flap or valve g,
substantially as herein described and shown with reference to Figs. 1 and 2 of the
accompanying drawings and for the purposes specified.
2. The modified form of insect or vermin trap comprising a preferably rect-
angular case such as a having an inwardly leading and converging passage P
the sides or a part of the sides h, h, of which are formed of thin, springy material
and meet or approximately meet at a point, substantially as herein described and

page_text: shown with reference to Figs. 3 and 4 of the accompanying drawings and for
the purposes specified.
3. The improvements in vermin or insect traps, substantially as herein described
and shown, and for the purposes specified.
Dated this 6th day of December, 1897.
