1 CHARLES BROTHERS of 15 Goodge Street London Builder & Decorator, do
bereby declare the nature of this invention to be as follows:
The object of my invention is to afford a ready simple effectual and inexpensive
means of obtaining ventilation in rooms or elsewhere.
This I effect by fitting a suitable plate hereafter termed a face plate of any
convenient dimensions and provided with any convenient number of openings or
apertures either on the stile or rail of a window sash or in any other convenient.
position. The stile or rail or other portion of the building whereon such face
plate is mounted serves as a foundation therefor and is provided with corresponding
openings or apertures to those formed in the face plate. Either series of openings or
apertures may be fitted with a screen of wire gauze. or other suitable material so as
to prevent dust.dirt and other impurities entering the room or apartinent when the
ventilator is open or partially so. I would here observe however that such screen can
be dispensed with if desired.
.
I also fit the foundation with pins or studs or other suitable equivalents which take
into suitable slots formed in the face plate therefor and so allow such face plate to
readily work to and fro. 1 fit the face plate with a knob ring hook or other
equivalent device for the purpose of operating the same to and fro in the manner
just described.
.
The operation of my invention is as follows. When desired to open or close the
ventilator it is only necessary to slide the face plate to or fro in the required.direction
by means of such knob hook ring or other equivalent device when the openings or
apertures are opened or closed or partially opened or partially closed as desired.
It is obvious from the foregoing description that my improved ventilator when
fitted in the manner above described is a single action ventilator but I would here
observe that whenever found desirable or advantageous to do so such improved
ventilator may be readily worked with a double action.

I CHARLES BROTHERS of 15 Goodge, Street London Builder and Decorator 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 afford a ready simple effectual and inexpensive
means of obtaining ventilation in rooms or elsewhere.
This effect by fitting a suitable plate hereafter termed a face plate of any
convenient dimensions and provided with any convenient number of openings or
apertures either on the stile or rail of a window sash or in any other convenient.
position: The stile or rail or other portion of the building whereon such face plate
is mounted serves as a foundation therefor and is provided with corresponding
openings or apertures to those formed in the face plate. Either series of openings
or apertures may be fitted with a perforated screen plate of wire gauze or other
suitable metal or material so as to prevent dust dirt and other impurities entering
the room or apartment when the ventilator is wholly or partially open. I. would
here observe however that such screen plate can be dispensed with if desired.
I also fit the foundation with pins or studs or other suitable equivalents which
take into suitable slots formed in the face plate therefor and so allow such face
plate to readily work to and fro when operated. I fit the face plate with a knob
ring hook or other equivalent device for the purpose of operating, the same to and
fro in the manner just described.
The operation of my invention is as follows-When desired to open or close the
ventilator it is only necessary to slide the face plate to or fro in the required direction
by means of such knob hook ring of other equivalent device when the openings or
apertures therein and also in the foundation are opened or closed or partially opened
or closed as desired.
It is obvious from the foregoing description that my improved ventilator when
fitted in the manner above described is a single action ventilator.
I would here observe that with regard to glass hit and miss ventilators I make no..
claim to that feature of my invention which consists in converting the window pane
into a foundation plate whereon to mount a movable face plate as this particular
detail of construction has long been well known in connection with glass hit and miss
ventilators when fitted in windows and elsewhere. :

fixed to the top rail of a sash. The dotted lines in this figure indicate one of the air
holes drilled in such top rail.
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.
.
1º. Forming a hit and miss ventilator by making suitable apertures in the stile
or rail of a window or other sash or any other suitable foundation and fitting the.
same with a slotted and perforated face plate working on screw pins or studs or
their equivalents and operated by a knob ring hook or other equivalent device all
substantially in the manner herein before described and shewn.
20. Fitting a hit and miss ventilator so constructed and arranged with a
perforated screen plate made of wire gauze or other suitable metal or material
substantially in the manner and for the purposes hereinbefore described and
shewn.
3°. In a glass hit and miss ventilator forming two or more slots in the face plate
of the ventilator and fitting the foundation plate with two or more pins, studs or
other suitable equivalents whereon the face plate when operated works to and fro all
substantially in the manner and for the purposes hereinbefore described and shewn.
