An Improved Bait Trap for Mice, Rats, and the like.
I, JAMES HENRY ATKINSON, of Hunslet Road, in the City of Leeds," Model
Maker, do hereby declare the nature of this invention' to be as follows:-
This invention refers to traps for catching and killing mice, rats and the
go off" by a pull at the bait; and has
like, in which the trap is caused to
more especially for its object to obtain ease and facility in setting, and certainty
of action with the minimum risk of the trap going off" prematurely whilst
being set and handled; and constitutes such a modification of the invention
referred in the Specnfication of Letters Patent No. 27488 of 1898 as to transform
a trap constructed according to said specification from a treadle trap to a bait trap.
A bait trap constructed according to my present invention, retains the com-
pound spring and trapping frame and catch lever as referred to in my said
the treadle however is dispensed with, and
Specification No. 27488 of 1898;
corresponding thereto the base board is neither cut nor recessed, but consists of
a plane piece of board of any suitable shape, but most conveniently rectangular
in plan and both side and end elevations.
In place of the treadle and catch lever staple referred to in the above men-
tioned Specification No. 27488 of 1898, 1 provide a bait hook staple, which forms
both a catch to hold the catch lever and thereby the trapping frame set, and a
hook to which the bait is attached. In its cheapest and most convenient con-
struction, the bait hook staple consists of a short piece of coppered wire, formed
with a loop at its lower end, by which it is hinged to a plain staple driven into
the base board, and a similar loop at its upper end; the wire on completing the
upper loop being bent in a forward direction (i.e. in a plane at right angles to
the plane of the loop) in the form of a hook. Both loops are preferably and
5 most conveniently formed in the same plane.

COMPLETE SPECIFICATION.
An Improved Bait Trap for Mice, Rats, and the like.
I, JAMES HENRY ATKINSON, of Hunslet Road, in the City of Leeds, Model
Maker, 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:
This invention refers to traps for catching and killing mice, rats and the

"

page_text: more especially for its object to obtain ease and facility in setting, and certainty
of action with the minimum risk of the trap "going off" prematurely whilst
being set and handled; and constitutes such a modification of the invention
referred in the Specification of Letters Patent No. 27488 of 1898 as to transform
a trap constructed according to said specification from a treadle trap to a bait trap.
A bait trap constructed according to my present invention, retains the com-
pound spring and trapping frame and catch lever as referred to in my said
Specification No. 27488 of 1898; the treadle however is dispensed with, and
corresponding thereto the base board is neither cut nor recessed; but consists of
a plain piece of board of any suitable shape, most conveniently rectangular
in plan and both side and end elevations.
In place of the treadle and catch lever staple referred to in the above men-
tioned Specification No. 27488 of 1898, I provide a bait hook staple; which forms
both a catch to hold the catch lever and thereby the trapping frame set, and a
hook to which the bait is attached. In its cheapest and most convenient con-
struction, the bait hook staple consists of a short piece of coppered wire, formed
with a loop at its lower end, by which it is hinged to a plain staple driven into
the base board, and a similar loop at its upper end; the wire on completing the
upper loop being bent in a forward direction (i.e. in a plane at right angles to
the plane of the loop) in the form of a hook. Both loops are preferably and
most conveniently formed in the same plane.
And in order that my invention and the manner in which the same is to be
performed may be more readily and clearly understood, I have annexed hereto
the accompanying drawing of a trap constructed in accordance with my inven-
tion, in which the trap is shewn as set; the dotted lines however shewing the
position of the trapping frame after the trap has gone off.
a indicates the base board of the trap, which as shewn consists of a plain
rectangular slab of wood.
bc is the compound spring trapping frame, & indicating the spring portion,
and the trapping frame.
d is the catch lever, hinged or looped to a plain staple e driven in the base
board near the back edge; and which serves to hold down the trapping frame c
when set.
fi is the catch lever staple or bait staple, hinged on looped to a plain staple g,
driven into the middle of the base board a, immediately in front of the spring b;
and bent so as to form a lower loop f engaging with the staple g; and an
upper loop formed at right angles to, so as to receive the free end of the catch
lever d, and to hold it and consequently the trapping frame set. The end of
the wire is turned up in a vertical plane parallel to the catch lever d, so as to
form a bait hook i; so that a pull by the animal at the bait tends to draw the
bait staple off the end of the catch lever d, releasing the trapping frame c, and
allowing the trap to go off.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. In a bait trap the combination of a plain slab of wood a compound spring
trapping frame a hinged catch lever and a bait hook staple substantially as herein
set forth and illustrated by the accompanying drawing.
2. The construction of a bait hook staple substantially as and for the purposes
herein set forth.
