COMPLETE SPECIFICATION.
Improvements in Apparatus for Wall and Window Ventilators.
I EZRA HATTON Engineer 110 Sackville Street Manchester, 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:—
The object of my invention is to produce a ventilator which will intercept smuts
and dirt prevent draughts be self cleaning and is applicable to hopper ventilators
for windows or walls and for ordinary sashes and sliding frames.
My invention is carried into effect as follows. On the top of hopper shaped
ventilators a plain or corrugated wire gauze or perforated screen or cover is fixed
for diffusing the air, avoiding draughts and for preventing smuts from passing into
the room, this gauze is automatically cleaned by means of a brush which is kept in
contact with the gauze when opening or closing the ventilator and may be fixed
over or under the gauze, at the sides a flexible tube is fixed to prevent draughts
from passing between the stationary and working parts.
The gauze, brush and flexible tube may be applied to any kind of window
sashes or sliding frames.
Fig. 1. is a section as applied to hopper ventilators with stationary sides or
cheeks.
A is a gauze screen or cover fixed at the top of the ventilator through which
the air is admitted, B is a section of the front of ventilator hinged at the bottom,
C is a brush firmly secured into a metal groove or channel D, and fixed on the top
of the ventilator front B so that when the latter is moved to and fro to open or
close the ventilator the brush C is kept in contact with the gauze cover A, thus
automatically cleaning the gauze and also excluding smuts and draughts.
Fig. 2. is a section as applied to hopper ventilators with sides or cheeks which
are not stationary, but which move to and fro with the front of ventilator when
opening or closing.
A' is the gauze cover fastened to the top of ventilator B' is a section of the

page_text: front of ventilator and hinged at bottom C¹, is a section of the brush which is
fixed to the stationery or outer frame of ventilator so that when opening or closing
the latter the brush C is kept in contact with the top of the gauze A.
Fig. 3. is a section shewing how wind rain and dirt, are prevented from passing
between the sides of the working and stationary parts of the ventilator when open
closed or partially open.
E, is a flexible tube of cloth felt or other suitable material inserted into a metal
groove or channel F, which is firmly pressed together so as to securely hold the felt
without the aid of cement or glue, G, is a section of the stationary parts of the
ventilator, H, is a section of the working or moving parts.
Fig. 4 is a section of a sash or sliding frame.
A is a gauze screen.
(2 is a section of the brush secured into a metal flanged groove for fixing to the
top of sash or sliding frame.
B2 is a section of the top of a sash or sliding frame, the brush C2 moves
parallel and in contact with the gauze A when opening or closing the sash or
sliding frame.
Having now particularly described the object of my invention and shewn how the
same may be carried out I claim as my invention
First. The arrangement for attaching to any kind of hopper ventilators a
perforated or gauze cover or screen in connection with a brush for automatically
cleaning the dirt off the gauze and also for the exclusion and interception of smuts
and avoiding draughts the corrugation of the gauze materially assisting in accom-
plishing this object.
Second. The method of securing flexible tubing by means of a metal channel
or groove which is pressed tightly together to retain the flexible portion without
the aid of glue or cement, for the exclusion of draughts and dirt between the
stationary moving parts of ventilators.
Third. The application of the gauze and brush to sashes or sliding frames.
