the bascule, attached to the bascule is a tigg or upright piece extending towards
the top of the trap movement of the bascule operates this piece, the entrance
to the trap is at one end and is supplied with a door preferably hanging from the
top and opening inwards this door on being raised catches in the tigg and is held
open by the weight of the outer end of the bascule the animal enters at the open
doorway passes the fulcrum of the bascule and by its weight depresses the inner
end this operates the tigg and releases the door which thereupon falls and encloses
the animal this door may be actuated by a spring or by its weight at the other end
of the trap a door is fitted to which bait can be attached in any convenient

COMPLETE SPECIFICATION.
Improvement in Traps for the Capture of Rats, Mice, and other
Animals.
We, WARREN THOMPSON, Gentleman of 46 Parchmore Road, and FRANCIS
BUCKLAND, Surveyor of 8 Beulah Road, both of Thornton Heath, Surrey, 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:-
Our invention relates to that class of trap which is automatically operated by
the weight of the animal to be captured, and the size of the trap will be
proportionate to the dimensions of the animal to be secured.
The body of the trap is made preferably of the tunnel or box form, and of
suitable material, preferably thin metal.
That our invention may be better understood we have attached hereto a sheet of
drawings in which Figs. 1 & 2 are a section and end elevation of one form of trap,
and Figs. 3 & 4 similar views of another.
Similar letters on all the figures refer to similar parts.

page_text: The body A. E. F. Figs. 1 & 2 may be perforated or plain, or made of open
work to suit the constructions and requirements. The bottom B. B' is arranged
as a bascule or platform hung on a wire C, or other suitable pivot, to act as a
fulcrum for said bascule B. A tigg D is attached to or formed on the bascule B,
preferably in an upright position extending towards the top of the trap, and any
movement of said bascule will therefore operate the tigg D. The entrance to the
trap is at one end E. the other end F being closed. The entrance is provided
with a door G, preferably hanging from the top A, and carried on a suitable
pivot H, so as to open inwards. This door is arranged so that the lower end of it
will rest on the tigg D; when opened, as shown by the dotted lines; and the outer
end B', of the bascule is made heavier than the inner portion B, to maintain the
bascule & door in their open position ready for the animal to enter. The bait
will be placedat.K as shown.
The action of the trap is as follows:-The animal enters at E and passés over
the bascule till its weight is greatest at the side B, when that end of said bascule
will be depressed, and move the tigg D from under the door G, which will
therefore fall and close the trap.
The door G may be actuated by a spring; or be made heavy, so as to close
quickly, while a suitable stop M and falling catch N engaging in a hole in the
bascule B will be provided to prevent the door from being moved when closed.
The bait K may be inserted through a suitable door in the end of the trap, and
will be held by any of the well known devices.
Instead of a door G, the arrangement shown in Figs. 3. & 4. may be used, the
upper part of the body of the trap-being-pivotted at Lso. that it may be lifted
and supported on the projection O resting on the tigg D as described with
reference to door G. The part E will then be solid or arranged to act as the door
when closed, as shown by the dotted lines.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is
1. In traps for capturing animals, the support or tigg, actuated by the bascule
as and for the purposes. herein described.
