PROVISIONAL SPECIFICATION.
An Improved Attachment for the Entrance of Pigeon Cotes.
We, PERCY MEE Gentleman and JOHN WILLIAM HAND Gentleman both of
Dowdeswell Street Chesterfield do hereby declare the nature of this invention to be
as follows:-
The object of our invention is to provide to the entrance of the pigeon cote a fixed
attachment so formed with a balancing board as to prevent the entering in to a
pigeon cote, of any bird or animal of a heavier weight than the ordinary pigeon and
our invention is, specially intended for the protection of pigeons in a cote from cats
and such like animals. In front of the entrance hole to the cote I attach an oblong
upright box open at the back and front and a little way up from the bottom we fix a
stout wire horizontally across the front and upon this wire we place a horizontal
board which we call a balancing board, and this board is pivotted upon this horizontal
wire. The board extends about the full depth of the oblong box and also projects
about half the said depth in front of the box. A small spring may be fixed from
the underneath side of the balancing board within the box to the floor of such box,
and the balance of the aforementioned balancing board is arranged so that a pigeon
may alight upon the outside and walk into the cote without disturbing the balance
ot such board, but should a cat or similar animal get on to the projecting outward
part of the board it would immediately weigh up the inner portion, which would
effectually block up the proper entrance to the cote, and the animal would also
slide off the leaning board. When the weight is taken off this outer portion, the
balancing board will return to its normal horizontal position. The entrance to the
cote itself may he provided with the usual bobwires, which are movable inwardly
when the bird prosses against them; and these wires work on a hinge fastened to
the head of the box where they can be put up and so be out of the way.
As our improvements are capable of some modification without departing from the
principle thereof, we do not restrict myself to materials or dimensions or the precise
placement of the various parts thereof.

COMPLETE SPECIFICATION.
An Improved Attachment for the Entrance of Pigeon Cotes.
We, PERCY MEE, Gentleman, and JOHN WILLIAM HAND, Gentleman, both of
Dowdeswell Street, Chesterfield, 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 pigeon's cotes and has for its object to
prevent the entrance therein of depredatory animals, heavier than a pigeon such as
cats and the like, and yet to allow free ingress to the inmates thereof. My invention
consists in fixing an entrance frame or casement in the opening of a pigeon's cote
and in pivoting a balance board at the lower part and between the two uprights of
the said frame. This balance board is furnished with a central slot extending to the
inner end of the same, and divided lengthwise in two parts by a bar.
This slot is covered on the upper as well as on the lower surface of the balance
box, and at its rear edge by a rectangular piece of metal or other suitable material,
thus forming a box, the two compartiments of which contain a number of leaden balls.
The balance board is so adjusted that a pigeon may alight on the front and projecting

page_text: end of this board, and freely enter in the cote, whereas a heavier animal such as a
cat would trip the same and cause its inner end to be raised against the frame afore-
said, and thus close the entrance to the cote.
In the accompanying drawings
Fig. 1 is a front view of my entrance frame or casement and balancing board,
Fig. 2 being a central vertical section of the same.
Fig. 3 is a plan of the balance board with the cover removed, and
Fig. 4 shows a pigeon cote, the openings of which are furnished with my improved
safety device.
The entrance frame or casement consists of a front or facia f, furnished with an opening.
and a cross bar b. This front is fixed to the upper part of the rectangular frame F,
leaving between the bar b, and the bottom bar 61, of the latter frame, an opening for the
passage of a balance board B furnished with two pivots p p¹, inserted and moving freely
in the eyes e e¹, the screw threaded ends of which are screwed in the front edge of the
frame F, so that the front part of this board projects a short distance outside the
opening o, and a somewhat longer distance within the cote. This board B is furnished
with a slot S, covered on the top underneath, and at its rear end with pieces a a¹ a²,
respectively of metal wood or other suitable material. A bar c divides the box thus
formed into two compartments, containing leaden balls d d . At the rear of the
facia, a doubly bent wire w, is carried at the top by a tubular support s, and is
capable of moving freely to and fro therein; its two pointed extremities rest against
the rectangular wire frame g, pivoted at its bent ends ii in the sides of the frame F.
The end, which is bent up to serve as a lever is curved so as to form an eye to
which is attached one end of a string n, the other end of which is pulled whenever it
is required to raise the two wire frames g and wand thus afford a free exit to the
pigeons in the cote, while on the contrary when the wire frame is in the position
shown in Fig. 2 and the string n, hangs loosely by the side of the frame F, the
animals can enter, but not come out again; m is a piece of leather arranged at
the bottom of the slot S, above the cover a¹ to deaden the noise of the balls when
rolling.
The balance board B, is so adjusted and weighted, that when a pigeon alights
on the front or rounded part thereof, it remains in the position shown in Fig. 2, but
should a heavier animal such as a cat for instance jump on the same part, the
board B would be tripped and assume the position shown in dotted lines in the same
figure, the leaden balls d d
rolling towards the front of the board, thus closing
the opening o, while the inclination of the front part of the said board, would cause
such animal to slip off the same, when the board resumes its former and normal
position, the balls rolling now backward.
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). The improvements in pigeon's cotes whereby the entrance thereto is freely
open to these birds, but is closed to heavier animals substantially as described and
shown in the drawings, and for the purpose set forth.
(2). In pigeon's cotes the combination of an entrance frame or casement with a
balancing board substantially as herein described and shown and for the purpose set
forth.
