Complete Specification Accepted, 7th Dec., 1888
I, CHARLES WARREN, of 13, Fore Street, Ipswich, in the County of Suffolk,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in that class of vermin trap in which a
spring flap is used, such flap being held open by a loose catch the lower end of which
carries the bait. When the bait of the trap is pulled or moved by an animal in the
trap the catch is released from its engagement with the flap and the spring brings
'down the flap and closes the trap.
This arrangement presents several objections amongst which may be mentioned
that the spring acting against the catch an animal can frequently eat or carry away
the bait without releasing the catch; and further the spring in time becomes weak
and the animal is enabled to raise the flap against the spring and escape from the
trap.
According to my invention I obviate these defects by employing no spring to the
flap, and by applying to the trap a suitable catch or stop arrangement which falls with
the flap and holds it in its closed position until released.

page_text: I, CHARLES WARREN, of 13, Fore Street, Ipswich, in the County of Suffolk,
Engineer, 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 improvements in that class of vermin trap in which a
spring flap is used, the said flap 'being adapted to be held open by a loose catch
carrying a bait at its lower end, in such a manner that, when the said bait is pulled
or moved by an animal in the trap, the catch is released from its engagement with the
flap so that the spring brings down the flap and closes the trap.
This arrangement presents several objections amongst which may be mentioned
that, the spring acting against the catch, an animal can frequently eat or carry away
the bait without releasing the catch; and further the spring in time becomes weak
and the animal is enabled to raise the flap against the spring and escape from the
trap.
According to my invention I obviate these defects by employing no spring to the
flap, and by applying to the trap a suitable catch or stop arrangement which falls with
the flap and holds it in its closed position until released.
To enable my invention to be fully understood, I will describe the same with
reference to the accompanying drawing, in which
Figure 1 is a plan of a vermin trap having my improvements applied thereto, the flap
being shown in its raised or open position, and
Figure 2 is a section of the same on the line x, x.
וי
Figure 3 is a view similar to figure 2, but showing the flap in its closed position.
a is the body of the trap and bis the flap which is hinged on the wire c and
provided with the arm d.
e is the catch which engages with the arm d to hold the flap open, and which at
its lower end is adapted to carry the bait.
fis the stop which holds the flap in its closed position. This stop is pivotted in
the walls of the trap, as shown most clearly in figure 1, and during the time that
the flap is open it lies upon the top of the flap, as in figures 1 and 2. When,
however, the flap is released, the said stop falls with the flap to the position shown
in figure 3, so that the said flap is securely locked.
is a
pin which prevents the stop from moving too far.
wish it understood that I do not limit my invention to the form of stop
shown, as it is obvious that the same can be considerably modified without departing
from the nature of my invention.

page_text: 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 :-
(1.) In a vermin trap, the combination with the hinged or pivotted flap, of a
stop adapted to fall with the said flap, and to lock the same in its closed position,
substantially in the manner, and for the purpose, described.
(2.) The manufacture and use of the improved vermin trap hereinbefore described
and illustrated in the accompanying drawing.
