PROVISIONAL SPECIFICATION.
Improvements in Ventilation.
I, WILLIAM CARSON TOONE of the Wiltshire Foundry, Warminster in the
County of Wiltshire, Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to " Improvements in Ventilation" which improvements
may be applied to any part of the walls of a room or apartment, but is more
especially suitable for application to windows the sashes of which slide to open
and in different vertical planes. It consists in general either of a modified form of
one or both of the meeting-bars, or of an attachment thereto which forms an
opening or openings for the free admission of air to the interior of the room or
apartment to which it is applied, such openings being preferably formed by
'perforated metal, or reticulated wire, and in some cases covered with a plate or
plates forming a valve, generally of the "hit or miss" description, and the
operation of which is capable of being controlled conveniently from the interior of
the apartment. It will be understood that the principle remains the same whether
openings are formed in and constitute part of the meeting-bar or bars of the
window sash, or are separately manufactured and fitted so as to immediately cover
an opening or openings in the meeting-bar.
In the case of a window of the ordinary construction the sashes of which slide
in different vertical planes, the opening of such orifices would allow of the free
influx of a current of air from the the outside to replace the vitiated heated air
which is to be carried off in any convenient ordinary manner.
In the case of the ventilator being applied to the doors or any other part of the
walls of a room
or apartment than the window, the fitting would be of such
construction that the air entering would be deflected from a straight line."
An incidental advantage of this system is that the window may remain closed
and fastened while the ventilator is in operation.

COMPLETE SPECIFICATION.
Improvements in Ventilation.
I, WILLIAM CARSON TOONE, of the Wiltshire Foundry, Warminster, in the
County of Wiltshire, Engineer, 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 Ventilation which improvements may be
applied to any part of the walls of a room or apartment, but is more especially
suitable for application to windows, the sashes of which slide to open, and in
different vertical planes.
:
It consists in general of a modified form of one or both of the meeting-bars, or
of an attachment thereto which forms an opening or openings for the free admission
of air to the interior of the room or apartment to which it is applied, such openings

page_text: "
being preferably formed of perforated metal, or reticulated-wire, and in some cases
covered with a plate or plates forming a valve generally of the "hit or miss
description, and the operation of which is capable of being controlled conveniently
from the interior of the apartment.
It will be understood that the principle remains the same whether openings be
formed in and constitute part of the meeting-bar, or bars of the window sash, or
are separately manufactured and fitted so as to immediately cover an opening or
openings in the meeting-bar.
In the case of a window of the ordinary construction, the sashes of which slide
in vertical planes, the opening of such orifices would allow of the free influx of a
current of air from the outside to replace the vitiated heated air which is to be
carried off in any convenient and ordinary manner.
In the case of the ventilation being applied to the doors, or any part of the walls
of a room, or apartment other than the window, the fitting would be of such
construction that the air entering would be deflected from a straight line.
An incidental advantage of this system is that the window may remain closed
and fastened while the ventilator is in operation, even in cases where the ventilator
is combined with a fastener of any kind and both are operated by the same lever,
or its equivalent.
Where any part of the meeting-bar is occupied by a fastener as is generally the
case, I sometimes combine the ventilator with such fastener, so that the same lever,
or equivalent slide, may be used to fasten the window, and to operate the ventilator.
It is obvious that many different kinds of combined fastener and ventilator may
be used for carrying out the purpose of my invention, but I show only two typical
forms to illustrate the combination.
In the accompanying drawings, in which like letters refer to similar parts, or to
parts fulfilling the same functions:-
Fig. 1. is an elevation, as seen from the interior of an apartment, of a window
having two ventilators applied to the meeting-bar of the upper sash.
Fig. 2. is a plan,
:
Fig. 3. a longitudinal section, and
Fig. 4. a transverse section, all on an enlarged scale, of a simple form of
ventilator, according to my invention.
Fig. 5. is a plan,
Fig. 6. an elevation, and
Fig. 7. a transverse section of a combined fastener and ventilator.
Fig. 8. is a plan, and
Fig. 9. an elevation of a modified form of combined fastener and ventilator.
Fig. 10. is an elevation of a window, shewing a means of operating the fastener
and ventilator from the bottom of the window.
Fig. 11. is an elevation of a modified form of the device shewn in Fig. 10.
Fig. 12. is a plan,
Fig. 13. an elevation, and
Fig. 14. a transverse section of a ventilator, as applied to a door, wall, or other
vertical surface.
A designates the meeting-bar of the lower, and B the meeting-bar of the upper
sash, to which latter, the ventilator, or ventilators are shewn as fixed, or of which
they may form part. C is the ventilator and this may be made in many forms, but
is here shewn as consisting of a plate c let into and screwed or otherwise rigidly
fastened to the meeting-bar B. The plate c has a number of transverse slits c
formed in it as well as two longitudinal grooves e³, in which latter slides the valve
proper c. The valve c has slits c' similar to the slits c' in the plate c, and when
the valve is moved by pushing the knob c* into such a position that the slits c
are vertically above the slits c', each pair of coincident slits forms, an air passage
which allows of the free access of air from the outside atmosphere to the interior
of the apartment. On the other hand, when the valve c³ is moved to the other
position (as shewn in Figs. 2, 3, and 4) the access of air is entirely prevented.

page_text: are the screws for fixing the ventilator to the meeting-bar, and b is an opening to
allow free access of air to the under side of the ventilator. E are the glass plates
of the window sashes.
The ventilator is shewn as attached to the meeting-bar B of the upper sash, but
it may equally well be attached to the meeting-bar A of the lower sash, and in
either case the strength of that portion of the meeting-bar which is cut away to
form the air passage b may be made up by the use of an iron or other metallic
Lshaped piece to form the plate c of the ventilator.
Figs. 5, 6, and 7 shew a form of combined fastener and ventilator in which the
fastener G is of that kind which is most commonly used, consisting of a lever H,
moving in an arc of a circle on a pivot h, in such manner that when moved by the
knob g to one position it slides under the projecting catch g', and thus the window
sashes are securely fastened while if the lever H is moved to the other position,
(as shewn in Fig. 5) the lower sash may be moved upward without hindrance..
The lever fulfils a double function as it is utilized to operate the valve of the
ventilator, and this is effected by forming it with a projecting arm having a
slot h³, in which slot a pin c³ (forming part of the valve ³) takes in such manner that
the movement of the lever H, with its arm ', causes the pin c', and its attached
valve c³, to slide longitudinally to the extent required to open or close the ventilator
by causing the slits c¹ and c¹ to coincide, or otherwise. In this case for the proper
working of the combined ventilator and fastener three positions are necessary;
1st, when the lever H is in such a position that the window is free to open, (as
shewn in Fig. 5) the ventilator is closed; 2nd. when the lever H is moved half-way
of its arc of motion, the window is fastened, and the ventilator is opened; and
3rd. by moving the lever H the full extent possible, the window still remains
fastened, while the ventilator is closed. The 2nd. and 3rd. positions are shewn in
chain dotted lines in Fig. 5. It will be seen that in the combined fastener and
ventilator here shewn, the lever moves in a horizontal plane.
. But in Figs. 8 and 9 the lever H is shewn as pivoted at 1, and moving through
an arc of a circle in a vertical plane. It has a projection * which, in two out of
three possible positions of the lever H, takes under the projecting catch g', when
the window is fastened; while in the third position, (as shewn in the drawing) the
lower sash is free to slide upward, or the upper sash downward. The rocking of
the lever H on its pivot h moves a pin or a cam-shaped projection ', which in turn
operates a suitably shaped part c' of the valve c³, and causes it to occupy the three
different positions, in a similar manner to that described with reference to
Figs. 5, 6, and 7.
In some cases the meeting-bars of the sashes are at too great a height to be
conveniently reached, and Figs. 10 and 11 shew alternative methods of operating
the ventilator, or the combined ventilator and fastener from the bottom of the
window. It is necessary in these cases to fix the lever H, or its equivalent, upon
the meeting-bar of the bottom sash. In Fig. 10 the lever H and pivot his
operated by a rod I which extends downward, and is connected with a second
lever L pivoted at 1 on the window sash. The movement of the lever L gives a
corresponding movement of the lever H, and therefore of the ventilator, or
fastener.
In Fig. 11 the rod I and lever L are replaced by two cords, and tassels I, which
operate the lever H as before.
The valves hereinbefore shewn and described all slide parallel to the glass plates,
but they may equally well slide at any angle to these; in fact numerous
modifications of the ventilators and fasteners are possible without departing from
the essential features of my invention. The ventilators may extend the whole
length of the meeting-bar, or any part thereof.
Figs. 12, 13, and 14 shew a ventilator as applied to a door, wall, or partition M.
N is a metallic box having a vertical opening n, and a number of horizontally
disposed slits e¹ in the top c which forms the plate of the ventilator. The valve c
having slits slides upon the plate as before. The air enters by the vertical

page_text: opening n, is deflected upward and, when the ventilator is open, passes into the
room or apartment.

With reference to the combination of ventilator and fastener, any of the
numerous forms of window fasteners may be combined with a ventilator without
departing from my invention.
In general I apply a spring catch which indicates each of the positions of the
lever H, the spring dropping into a notch when either of these positions is reached,
but as these are not essential features of my invention, I have not shewn such in
the drawings.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is
1. A ventilator applied to either of the meeting-bars of a window sash.
2. The combination of a window fastener with a ventilator, substantially as
described.
3. The combined form of window fastener and ventilator operated by a lever or
its equivalent, moving in a horizontal plane.
4. The combined form of window fastener and ventilator, operated by a lever, or
its equivalent, moving in a vertical plane, or in an inclined plane.
5. The combination of a ventilator or fastener, or. both, with means for operating
the same from near the bottom of the window.
6. The ventilator as applied to a door or other vertical surface, substantially as
shewn and described with reference to Figs. 12, 13, and 14.
