PROVISIONAL SPECIFICATION.
Improvements in Ventilating Apparatus.
I, FERNAND DIETS, of 16 Rue Notre-Dame des Victoires, Paris, in the
Republic of France, Jeweller, do hereby declare the nature of this invention
to be as follows :—
My invention relates to ventilating apparatus particularly applicable to ventilating
rooms and apartments, and the chief object of my invention is to ventilate without
causing a draught, to purify the air entering by the ventilator, or to charge the air
with scent or any antiseptic.
In applying my improved ventilator to a window I propose to remove one pane of
glass and fix the ventilator to the outside of the window frame, or it might be to
the inside. A convenient arrangement consists of a casing composed of two end
frames preferably wider at the top than at the bottom and secured to the window
frame one at each end of the opening from which the pane of glass has been
removed. The end frames are about equal in depth to the opening and are
connected by say a sheet of glass.
In order to admit air to the ventilator I cover the upper part of the casing with
a sheet of glass or other suitable material held in a frame pivoted on brackets
carried by the end frames near the window opening at one end, and at the other by
adjustable rails carried also by the end frames and mounted in such manner that
the back portion of the glass can be readily raised by means of the rails so as to
admit more or less air as required.
In order to prevent impurities passing through the ventilator into the room I
propose to employ a sheet of wire gauze or other suitable fabric which is stretched
across the ventilator casing below the movable sheet of glass.
If it be desired to scent the air admitted, or to charge it with an antiseptic, a
convenient plan is to fix below the gauze a perforated pipe extending from end to
end of the ventilator casing and filling this with sponge or other suitable material
charged with scent etc., the perforated pipe being preferably made in two parts and
hinged together for this purpose.
This improved ventilator is readily cleaned, it offers but little obstruction to the
free admission of light, and when desired it can be applied in a similar manner to a
door or other convenient opening into a room or building.

Improvements in Ventilating Apparatus.

1 FERNAND DIETS, of 16 Rue Notre-Dame des Victoires, Paris, in the
Republic of France, Jeweller, 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 :-

page_text: In applying my improved ventilator to a window I propose to remove one pane
of glass and fix the ventilator to the outside of the window frame, or it might be to
the inside. A convenient arrangement consists of a casing composed of two end
frames preferably wider at the top than at the bottom and secured to the window
frame one at each end of the opening from which the pane of glass has been
removed. The end frames are about equal in depth to the opening and are
connected by say a sheet of glass.
In order to admit air to the ventilator I cover. the upper part of the casing with
a sheet of glass or other suitable material held in a frame pivoted on brackets
carried by the end frames near the window opening at one end, and at the other by
adjustable rails carried also by the end frames and mounted in such manner that
the back portion of the glass can be readily raised by means of the rails so as to
admit more or less air as required.
In order to prevent impurities passing through the ventilator into the room
I propose to employ a sheet of wire gauze or other suitable fabric which is
stretched across the ventilator casing below the movable sheet of glass.
If it be desired to scent the air admitted, or to charge it with an antiseptic, a
convenient plan is to fix below the gauze a perforated pipe extending from end to
end of the ventilator casing and filling this with sponge or other suitable material
charged with scent etc., the perforated pipe being preferably made in two parts and
hinged together for this purpose.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 represents the improved ventilator applied to one window in a window
frame.
Fig. 2 is an enlarged front elevation, Fig. 3 is an end view and Fig. 4 a
sectional end view on the line 4 4, Fig. 2, of a ventilator constructed according to
my invention.
In the drawings, A represents the body or frame of the ventilator which is
secured to the window frame by rails such as a, see Fig. 2; to the frame A is secured
a metal framing A' which supports a sheet of glass B which is set obliquely to the
plane m, n of the window, a second sheet of glass C is held in a frame which is
pivoted to the end frames on studs the front edge of the sheet C is supported
at one end by an arm D which is notched at d and d' the notch d being shown in
Fig. 3 resting upon one of the button headed pins E secured to one end of the
body A; the frame and the glass C is raised and lowered by a handle D'.
To studs carried by the body A is pivoted a sheet of fine wire gauze or other
suitable material F which extends the full length of the ventilator and rests when
closed upon a stud or pin h secured to a plate H which is, guided by a handle,
the stud end of which passes through a slot h of peculiar shape in one end plate A
and further by a pin which is secured to the end frame A and rests in a slot ³
cut in the plate H. When the handle is raised the plate H to which it is
secured raises the sheet of metal gauze F on its pivots fand it can be held there
by pushing the handle into the curved head of the slot . When in the
position shown in Fig. 4 the metal gauze F can be fastened by means of a catch or
bolt G.
If it be desired to introduce into the room or apartment to which the ventilator
is fitted air charged with an antiseptic or a perfume, I employ a suitable absorbent
material such as sponge, cotton wadding, wick, or the like, and impregnate. the same
with the antiseptic or perfume etc., and in order to apply the antiseptic material
conveniently I employ a perforated metal tube K preferably hinged along one side
into which the impregnated material is placed; this. tube is fixed about in the.
position shown in Fig. 4 so that the air passing through the ventilator will carry
forward some of the antiseptic.
.
The amount of air.to. be admitted to the room is regulated by opening, or closing
the top glass plate C by means of the handle D³.

page_text: This improved ventilator can be readily cleaned inside and outside, and it has
the advantage of offering but very slight obstruction to the passage of light into
the room. The ventilator can be readily applied to the outside of the window or
to the inside, or outside, of a door or other opening into a room or building.
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. A ventilator composed of a framework supporting a front plate of glass or
other suitable material, an adjustable upper plate pivoted so that its front edge
when closed rests upon the first plate, in combination with a pivoted or movable
sheet of gauze or equivalent, for preventing the admission of dirt into the ventilator
all substantially as and for the purposes described.
2. In combination with a ventilator as described the application of a tube formed
in two or more parts for the reception of an antiseptic perfume or other material
substantially as described.
3. The general construction combination and arrangement of parts forming the
improved ventilator substantially as described and as illustrated in the accom-
panying drawings.
