PROVISIONAL SPECIFICATION.
An Improved Trap for Catching Cockroaches or Blackbeetles and.
other Vermin.
I, JAMES RICHARDS of 154 Bradshaw Gate, Bolton in the County of Lancaster,
Wire Worker, do hereby declare the nature of my said invention to be as follows:-
This invention relates to an improved trap for catching cockroaches or blackbeetles
and other vermin, and consists of a circular or other metallic case or box having
circular or inclined sides, and a straight or a dished top with a circular or other shaped
opening formed in the upper part to receive a pivoted or balanced platform or inverted
dish with inclined or other sides, and a receptacle for "bait." The platform or
inverted dish is provided on the underside with an inclined chamber or cavity, and is
balanced upon a central spindle or pivot secured in any convenient manner to the
metallic case or box forming the trap. This allows the said platform or inverted dish
to oscillate or swing when operated upon by the weight of a cockroach or other vermin.
When vermin are attracted by the "bait" in the receptacle on the swinging platform or
inverted dish they climb the outer body of the trap and endeavour to reach the "bait."
The sides of the body of the trap are roughened or coated with any suitable substance
that will afford foothold, the inside being perfectly smooth to prevent the possibility
of climbing therefrom. Immediately vermin reaches the outer rim or edge of the
platform or inverted dish they are of their own weight precipitated into the interior of
the trap body, where they remain until emptied. The "bait" receptacle can be
constructed to receive "bait" of a liquid, semi-liquid, or paste like form.

COMPLETE SPECIFICATION.
An Improved Trap for Catching Cockroaches or Blackbeetles and
other Vermin.
I, JAMES RICHARDS of 154 Bradshaw Gate, Bolton in the County of Lancaster, Wire
Worker, do hereby declare the nature of my said invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-

Fig. 1 is a sectional elevation of a modification of my improved trap with a straight
top for catching cockroaches or black beetles and other vermin.
Fig. 2 is an outside elevation of Fig. 1.
Fig. 3 is a plan of Fig. 1.
Fig. 4 is a modification of my improved trap with a dished top.
Fig. 5 is a plan of Fig. 4.
Fig. 6 is a sectional elevation of the dished top or removable ring.
Fig. 7 is a plan of underside of Fig. 6 showing spring pieces.
Fig. 8 is a plan of a square trap made on my improved principle, and
Fig. 9 is a sectional elevation showing how the inverted dish or cone is canted
when operated by cockroaches or blackbeetles and other vermin in their attempt to
reach the "bait.”
In all the figures the same letters are employed to indicate corresponding parts.
A is the circular or other metallic case or box with the inclined or corrugated
sides B; Cis the straight top; D the bottom; E is a ferrule soldered to the bottom D;
Gis a vertical spindle or pivot loosely mounted in the ferrule E; F is an inverted
dish or cone, and H the receptacle for "bait" of a liquid, semi-liquid, or paste like
form. The case or box A is constructed by soldering or otherwise joining the
bottom D, top C, and the sides B together, leaving the opening I on its upper side.
To the bottom D is secured in any convenient manner the ferrule E to receive the
central vertical spindle or pivot G. The latter is loosely mounted in the ferrule E to
allow of removal when cleaning the case or box A and thus prevent injury to the
operator's hands.
Upon the spindle or pivot G is mounted the balanced inverted dish or cone F, with
the "bait" receptacle H. The underside of the "bait" receptacle H on the balanced
inverted dish or cone F is provided with the inclined chamber or cavity J to sit on
apex of the spindle G to allow of the inverted dish or cone F oscillating as in Fig. 9,
when operated upon by the weight of a cockroach or other vermin. The inverted dish
or cone F is slightly smaller than the opening I in the case or box A.
To facilitate emptying or cleaning the case or box A I can construct it, as shown in
Fig. 4, with a loose dished top K provided with the spring pieces L to secure it in
the opening I on the upper end of the case or box A. The dished top K with the
spring pieces L are shown more clearly in Figs. 6 and 7. If desired I dispense with
the ferrule E and secure the spindle or pivot G to the bottom of the case or box A by
soldering as shown in Fig. 4. The case or box A and the inverted dish or cone F can
be made square as shown in Fig. 8.
When cockroaches or black beetles and other vermin are attracted by the "bait" in
the receptacle H on the inverted dish or cone they climb the outer body of the case
or box A of the trap and endeavour to reach the "bait." Immediately vermin reach
or touch the outer rim or edge M of the inverted dish or cone F, the latter gives way
under their weight as shown in Fig. 9, by which they are precipitated into the interior
of the case or box A of the trap, where they will remain until emptied. The sides
of the case or box A are roughened by corrugations as shown in Figs. 1, 2, and 3, or
left plain as in Figs. 4, 5, 8, and 9 and coated with dull or distempered paint or any
other suitable substance that will afford or give them foothold. The inside of the case
or, box A is perfectly smooth to prevent the vermin climbing or returning from the
trap when once arrested.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is-
و"
1. In a vermin trap the use of the inverted dish or cone F and the "bait
receptacle H mounted loosely on the vertical spindle or pivot G, in combination
with the case or box A forming the body of the trap, substantially as described.
2. Roughening the sides B of the case or box A forming the body of the trap by

page_text: means of corrugations to give vermin foothold when climbing the outer inclined sides,
substantially as described.
3. The respective combinations and arrangements of parts forming my improved
trap for catching cockroaches or blackbeetles and other vermin, substantially as
described and as shown on the drawings.
