PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Opening and
Closing the Outlet of Poultry Houses, Pigeon Lofts, and
the like.
1, FREDERICK GEORGE WALCH of Stoney Lane, Lightcliffe in the County of
York, Railway Employee do hereby declare the nature of this invention, to be as
follows:
:-
The object of my invention is to close the outlets of poultry and pigeon houses
so as to prevent dogs, cats, foxes, and the like from entering same, at the same time
keeping out all draughts, also to automatically open same when required.
I construct my apparatus with a suitable frame having an aperture in same by
which the poultry, pigeons and the like may enter the houses, behind this frame
and working within suitable slides is a door which may have a suitable glass panel,
this door is raised by means of a chain, rope or strap secured to the top of the door,
such chain passing over suitable guide pulleys is attached to a balance weight or
spring.
Attached to one side of this door is a catch which when the door is closed
engages with a pivotted catch attached to a suitable hinged landing, this landing or
platform being kept in position by means of a spiral or other spring.
When the fowls and the like wish to leave the roost they step upon this landing
or platform slightly depressing same thus releasing the catch before described, the
door is then (by means of balance weight or spring before described) immediately
raised.
Dated this Fifth day of December 1893.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Opening and
Closing the Outlet of Poultry Houses, Pigeon Lofts, and
the like.
I, FREDERICK GEORGE WALCH of Stoney Lane, Lightcliffe in the County of
York, Railway Employee, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described aud
ascertained in and by the following statement:-
The object of my invention is to close the outlets of poultry and pigeon houses,
so as to prevent dogs, cats, foxes and the like from entering same, at the same time
keeping out all draughts, also allowing the same to be automatically opened when
required

page_text: I construct my apparatus with a suitable frame A, having an aperture B in same,
by which the poultry, pigeons or the like may enter the houses, behind this frame
and working within suitable slides C is a door D, which may have a suitable glass
panel E for lighting purposes, or the door may slide upon suitable guide rods, this
door is raised by means of a chain, rope or strap F secured to the top of the door,
such chain (passing over suitable guide pulleys G) is attached to balance weights
or springs H suspended within the frame A.
Attached in any suitable position but preferably to one side of this door is a
catch or recess J, which when the door is closed, engages with a pivotted catch or
finger K, attached to a suitable hinged landing L.
When the fowls or the like wish to leave the roost, they step upon this landing or
platform, immediately depressing same as shown in dotted lines at Fig. 2. thus
releasing the catch before described; immediately this catch is released, the door
is raised by means of the springs or weights before described.
As the fowls step off this landing or platform, it is returned to its original
position by means of a suitable blade or other spring M.
When closing the roost at night, the door is pulled down by a suitable handle or
knob, until the catch or finger engages with the recess or catch in the door, which
secures the said door until released by the fowls as before described.
A cross piece P may be employed where required for preventing the landing
being depressed too far.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:―
1. In poultry houses, pigeon lofts and the like, the use and employment of
apparatus for closing and automatically opening the exits or outlets of same, by
depressing a hinged or pivotted landing in the manner substantially as described.
2. For automatically opening the exits or outlets of poultry houses, pigeon lofts
and the like, the use and employment of a suitable hinged landing or platform L,
spring M, catch or recess J, catch or finger K, sliding door D, chains or ropes F,
pulleys G, and weights or springs H, operated in the manner, substantially as shown
and described.
Dated this Thirty-first day of August 1894.
