PROVISIONAL SPECIFICATION.
Certain Improvements in Vermin Traps and other Animal Traps.
I, WILLIAM HENRY TILDESLEY, of 88, Walsall Street, Willenhall, in the County
of Stafford, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to those vermin traps and other animal traps in
which a pair of spring jaws are used to close together by the action of a spring or
springs when one of the jaws has been released by the depression of the treadle.
When the trap is set a tongue which is hinged to the trap frame lies over one of the
jaws and engages with a catch on the treadle so as to hold down the jaw.
This invention has reference to the construction of the treadle and the cross har of
the trap frame to which the treadle is hinged, my object being to simplify the
construction of these parts and reduce the cost of their manufacture.
In carrying out my invention I make the treadle in a piece with the catch thereof
and at the sides of the catch part I form projecting ears which are bent down and
hinged to an upwardly projecting ear or ears formed in a piece with the cross piece
of the trap frame. The hinging of the said ears of the treadle to the ear or ears on
the cross piece of the trap frame may be effected in various ways, as by a rivet or
eyelet passing through the ears, or by the ears having projecting pips formed on
them which are bent inwardly to engage in the hole in the ear or ears of the cross
piece; or the ears of the treadle may be punched inwardly to engage in the hole
in the ears of the cross piece of the frame. The said cross piece may either be
formed with one or two ears for the treadle to be hinged to; the said ear or ears of
the cross piece consist of one or more projecting parts which are bent upwardly at
right angles thereto; or the ear or ears may be pierced and raised out of the body
of the cross piece. The treadle is by preference corrugated or otherwise raised with
the ribs or projecting parts to strengthen the same.

Certain Improvements in Vermin Traps and other Animal Traps.
I, WILLIAM HENRY TILDESLEY, of 88, Walsall Street, Willenhall, in the County
of Stafford, Manufacturer, 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 has reference to those vermin traps and other animal traps in
which a pair of spring jaws are used to close together by the action of a spring or
springs when one of the jaws has been released by the depression of the treadle.
When the trap is set a tongue which is hinged to the trap frame lies over one of
the jaws and engages with a catch on the treadle so as to hold down the jaw.
.

page_text: This invention consists of the improved construction of the 'treadle and the cross
bar of the trap frame to which the treadle is hinged, my object being to simplify
the construction of these parts and reduce the cost of their manufacture.
I will describe my invention by referring to the accompanying drawings in
which
Fig. 1 is a side elevation and Fig. 2 is a plan of an animal trap constructed
according to this invention;
Fig. 3 is a separate view of the treadle or bait plate of the trap, and Fig. 4 is a
separate view of the cross bar or bridge of the same ;
Fig. 5 shews another method of constructing the treadle and cross bar in
accordance with this invention ;
Fig. 6 shews how the blanks for forming the cross bar Fig. 5 can be cut out of a
strip without waste ;
Fig. 7 shews another arrangement of the cross bar with my improved treadle; and
Fig. 8 shews my improved treadle applied to a cross bar which is made in the
ordinary way.
The same letters of reference indicate the same or corresponding parts in all the
figs. of the drawings.
'A' A² are the two spring jaws of the trap jointed to the trap frame B¹ B²; C is
the spring which causes the jaws to close when one of them has been released by
the treadle D; E is the tongue hinged to the cross bar B2 of the trap frame and
which lies over the jaw A2 when the trap is set so as to engage with the catch a on
the treadle D to hold down the jaw.
In carrying out this invention I make the treadle D from a sheet metal blank in
a piece with the catch d' thereof and with the ears d³ which are bent down as
shewn in Fig. 3 and near their lower ends are jointed to the cross bar B2 of the
trap preferably by the cross bar B2 being bent upwardly at as shewn in Fig. 4 this
upwardly bent part having projecting pips or pegs 263 projecting from its sides
which engage in the holes 1f2 formed in the ears d² ds of the treadle D. By
making the treadle D in a piece with its catch d' and said ears d² d³ as above
described and shewn in Figs. 1 2 and 3 (and as shewn in Figs. 5, 7 and 8 herein
after described) the cost of manufacture is reduced and the trap is improved as
there is no possibility of the ears or catch becoming detached from the treadle as is
sometimes the case when the ears and catch are made separate from and riveted to
the treadle in the usual way.
.
In order to strengthen the treadle D I may form a projecting rib d' round the
edge of the saine as shewn.
My improved combined treadle and catch made as above described may be hinged
or jointed to trap frame cross pieces which are formed in other ways than that
shewn by Fig. 4. The said cross bar may for instance as shewn in Fig. 5 be made
with a projection b at one side which is turned up as shewn in Fig. 5 to form an ear
to which the ears d² d³ of the treadle D are jointed by a pin or rivet 9 passing
through the same. This cross bar formed with its ear 6 in a piece therewith as
shewn forms one feature. of this invention. By cutting the blanks for the cross
bar B2 of Fig. 5 in a zig-zag form as shewn by Fig. 6 to make the ears 6 there is,
as will be seen by an examination of this fig., no waste of metal as the part for
forming the ear 6 of one cross bar fits into a corresponding depression in the
next.
Fig. 7 shews my improved combined treadle and catch applied to a cross bar B
(which latter however forms no part of this invention) which is made in another
way namely from the usual straight strip of metal from the end of which a T-shaped
bit H is cut leaving the hole 65 for the tongue E and this bit H is riveted to the
cross bar B2 so that the upper part of the T will form the two pins on which the
ears d d of the treadle are jointed.
Fig. 8 shews my improved combined treadle and catch applied to a trap which
has its cross bar B made in the usual way with two separate ears
thereto to which the ears d² d³ are jointed by the cross rivet or pin g.
rivetted

tion and in what manner the same is to be performed I declare that what I
claim is :-

2. In vermin traps and other animal traps of the kind herein referred to, making
the cross bar B2 of the frame with a side projection which is turned upwardly and

before described with reference to Fig. 5 of the accompanying drawings.
5. In a vermin trap or other animal trap of the kind herein referred to, the
combination, with the trap frame the jaws hinged to the frame and the spring for
closing the jaws, of the cross bar B2 made with the T-bit H and the bait plate or

to the cross piece B' to engage under the catch d¹ of the treadle, the whole forming
a trap constructed substantially as hereinbefore described with reference to Fig. 7 of
the accompanying drawings.
