PROVISIONAL SPECIFICATION.
An Improved Animal Trap.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, (a communication to me from abroad by Homer Jefferson
Barry, of Fargo, Michigan, U.S.A., Inventor,) do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improved animal trap more particularly adapted for
catching mice. The invention comprises a preferably rectangular box, having its
sides somewhat higher than its ends. At the top of this box, on a level with its
ends, are two sliding doors, which extend across the box only a short distance; the
remaining space being closed by two trap-doors, which are pivoted from side to side
of the box. The two upwardly extending sides are connected by a cross piece, and
the channel thus formed between this cross piece and the trap doors below it, is
divided by a glass partition. At one end of the box is an entrance, the inner side
of which entrance is protected by an inwardly extending perforated piece of metal,
which projects over an inwardly opening gate constructed of pegs, secured to a
horizontal bar pivoted across the entrance. Near the other end of the case is a
division which forms a compartment divided off from the rest of the box, and in
which is placed the bate. The entrance from the larger compartment into the bate
compartment is provided with a door which opens into the bate compartment, and
will only open one way. The operation is as follows-The mouse or other animal
can either enter the channel at the top of the trap, towards the glass partition, and
in treading upon one of the trap doors is precipitated into the larger compartment,
from whence it enters through the door leading to the bate compartment, from
whence it cannot escape.
The mouse or other animal can also enter the entrance
at the end of the box, from whence it enters the bate chamber.

COMPLETE SPECIFICATION.
An Improved Animal Trap.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from abroad by Homer Jefferson Barry, of Fargo, Michigan,
U.S.A. Inventor,) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to animal traps, and most particularly to that class which
are self-set and ever set.
The object of this invention is to provide a trap that will be simple and efficient,
and which will tempt the animal and ensnare him before he is fully aware of the
dangers that beset him. The bait-box is arranged upon either or both sides of the
entrance, and is closed on the side adjacent the said entrance by a perforated wall,
the perforations being of such size as to permit the animal to nearly reach the bait,
thereby luring him into the trap. The trap is provided at one end, the end
opposite the entrance, with a receiving-compartment, into which the animals collect
and from which they are removed through a glass door.

page_text: The improvement consists of the novel features, which hereinafter will be more
fully described and claimed, and which are shown in the accompanying drawings,
in which-
Figure 1 is a vertical central longitudinal section of a trap embodying my
invention, showing the operation of the trap-doors by dotted lines.
Fig. 2 is a top plan view, parts being broken away, showing the bait-box at the
entrance end of the trap and the guard at the entrance to the receiving-
compartment.
Fig. 3 is a detail view of the guard in the receiving-compartment.
Fig. 4 is a front view, parts being broken away, of the trap.
The case comprises sides A, ends B and B' and bottom C. The sides A project
some distance above the tops of the ends B and B' and are closed on the top by the
cover D. The two trap-doors E and E', arranged about on a level with the tops
of the ends B and B', extend between the sides A, and their inner ends meet about
midway between the ends of the trap. The glass partition b, arranged in line with
the meeting ends of the trap doors E and E', prevents an animal from running
through the space between the cover D and the trap-doors E and E. The trap-
doors are journalled at their edges in the sides A, and are heavier at their outer
ends to close after the animal has depressed their inner ends and been precipitated
into the trap. The sliding doors F and F close the space between the ends B
and B and the journals of the doors E and E', respectively, so that when the inner
ends of said doors are depressed no space will be provided for the escape of the
entrapped animals. The end B is provided with opening G. On each side of this
opening are arranged perforated walls g, which extend back into the trap some
distance. A series of downwardly-inclined needles H are arranged over the space
between these two perforated walls, being pivotally supported at their upper ends
on the rod at the top of the said opening G, and limited in their downward
movement by passing through slots i in the top plate I, depending from the plate P,
which extends over the space between the said walls g g and is supported thereon.
The bait-boxes J are placed upon either side of the opening G, and the perforated
walls form one side thereof. The perforated walls g 9, projecting in from the sides
of the opening G, form a passage between them through which the animal passes
to gain entrance into the trap. The needles H ride over the. animal as he enters
the trap through the said passage and prod him if he attempts to escape, thereby
preventing his escape. The animal sniffs the bait through the openings in the
walls 9 g, and is thus lured on until trapped.
The vertical partition K divides the trap into two compartments, the entrance
and the receiving compartments, the latter retaining the animal until a disposition
is to be made thereof. The opening k in this partition K is protected by the wire
guard J' and the inclined needles L, the latter being limited in their downward
movement and spaced apart by the wire stop M, which is bent in a series of return
folds m.
The end B' is provided with an opening n, which is closed by the glass door N.
This opening n is opposite the opening & in the partition K, and the animal in the
entrance-chamber seeing the light in the receiving-compartments enters the same,
and is held captive therein until disposed of.
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 1
claim is :
1. In an animal-trap, the combination, with the case having an entrance-opening,
of perforated walls on each side of the said opening, and the bait-receptacle on the
inner side of the said perforated walls, substantially as described.
2. In an animal trap, the combination, with bait-boxes on each side of the
entrance-opening, of perforated walls on each side of the said opening forming a
side of the said bait-boxes, substantially as described.
3. In an animal-trap, the combination, with the case having cover D, of the two

page_text: trap-doors placed below the cover, and the glass partition arranged in line with the
meeting ends of the said doors, substantially as and for the purpose described.
4. In an animal-trap, the combination, with the case and the two trap doors, of
the sliding doors F and F¹, closing the space between the front ends of the case
and the front portions of the said trap-doors, substantially as and for the purpose
described.
5. In an animal-trap, the combination, with a wall having an entrance, as k, and
a guard projecting from the sides of the said entrance, of the needles L, pivotally
supported at the upper end of the said entrance k and inclining downwardly, and
the stop M, bent in a series of return folds and adapted to limit the downward
movement of the said needles, substantially as set forth.
6. The herein-specified trap, composed of the case having its sides higher than
the ends and closed by cover D, the trap-doors E and E', about on a level with the
tops of the ends and placed some distance below cover D, glass partition b in line
with the inner ends of doors E and E', sliding doors F below the front portions of
doors E and E', the perforated walls on each side of the entrance-opening, the bait-
boxes on each side of said perforated walls and the needles between them, the
partition K, the guard and needles protecting the opening in partition K, and the
glass door closing an opening in the end B¹ of the case, substantially as specified.
