This invention has for its object the admission of fresh air into every description.
of buildings, also into carriages, steamers, or sailing vessels and other constructions,.
with the absence of draught, and, when required, at an increased temperature.
To attain the admission of air without draughts I form a glazed vertical chamber,
on the inside of the ordinary glazing, which chamber prefer to make, expanding
to a large area at the top or outlet so that the incoming air may spread as well as
ascend after leaving the ventilator; this chamber has a glazed sloping bottom, and
immediately above is an opening in the ordinary glazing for the admission of the
external air covered by an adjustable hinged glazed flap.
When applied to the exterior of the ordinary glazing instead of the interior, I
form the vertical chamber in a similar manner but in this case the bottom is left.
open, the top sloped or weathered and an adjustable hinged flap at the inside of
the top forms the expanded top or outlet. By hanging the central portion of the
ventilator upon hinges as doors it is converted into an ordinary casement for use
in very warm weather.
The warming of the incoming air is effected by a narrow vertical chamber at
each side of the ventilator against the window jambs, made of copper or other
material, each of these chambers contains one or more gas jets with proper
arrangements for lighting, supplying air for combustion, extracting the vitiated.
air and cleaning the chamber; these gas jets heat the sides of the chambers, and,
consequently, the ascending air coming into contact therewith; the remainder of
the ascending air is made to mix with this heated air by glass deflecting plates.
placed near the top of the ventilator so that the whole of the air leaves the
ventilator at an increased and uniform temperature. The heating chamber can also
be placed at the bottom of the ventilator heated by a row of gas jets, in this case
the deflecting plates at the top are dispensed with.

Surveyor IMPROVEMENTS IN WINDOW VENTILATORS
This invention has for its object the admission of the external air into every
description of building, also into carriages, steamers or sailing vessels and other
constructions, with the absence of draughts upon the occupants of the same and,
whero required at a higher temperature than the external air.
To attain the admission of the external air without draughts I form a glazed
vertical chamber on the inside of the plane of the ordinary glazing of the window,
consisting of two glazed frames; the top of the inner glazed frame is fitted with
a hinged adjustable glazed flap so as to regulate the admission of the air; the inner
glazed frame is connected to the outer one by a glazed sloping bottom and an
opening formed immediately opposite the same in the outer glazed frame which,
when desired, may be fitted with a hinged adjustable glazed flap.
When applied to the Exterior of the plane of the ordinary glazing, I form the
glazed vertical chamber in the same manner with the two glazed frames; in this
case the bottom of the chamber forms in itself the opening for the admission of
the external air and the outer glazed frame is connected with the inner one by a
sloping or weathered top, the hinged adjustable glazed flap is fitted to the top of
the inner glazed frame as before for regulating the admission of the air.
The glazed vertical chamber can be formed partially on each side of the plane
of the ordinary glazing, in which case there is the sloping bottom to the inner
glazed frame and the hinged flap at the top of the same and the sloping or
weathered top to the outer glazed frame as before described.
By fitting the outer and inner glazed frames with doors to be hung either at
the top, the sides or the bottom, the ventilator can be thrown entirely open to the
external air for use in very warm weather.
The warming of the entering air is effected by a narrow vertical chamber or box-
at each side of the ventilator against the window jambs, made of copper or other
material; Each of these heating chambers contains one or more gns jets with
arrangements for lighting, supplying air for combustion, extracting the vitiated air,
and cleaning the chamber; these gas jets heat the sides of the heating chamber,
and this consequently heats the ascending air coming into contact therewith; the
remainder of the ascending air is made to mix with this heated air by glass
deflecting plates placed near the top of the ventilator, so that the whole of the air.
leaves the ventilator at an incrensed and uniform temperature.
The heating
chamber can also be placed along the bottom or the top of the ventilator heated
by a row of gas jets; in those cases the deflecting plates are dispensed with.
The arrangement by which the henting chamber is placed along the bottom of
the ventilator 1 consider to be the one most likely to meet ordinary requirements,
and also to be the most efficient arrangement, and I have, therefore on the drawings
accompanying this specification illustrated the manner in which I propose to apply
it comprising a horizontal chamber fitted with a row of gas jets and projecting
gills" to add to the henting surface, the inlet to the same supplying the air
required for combustion which is taken from the apartment to be ventilated, tho
tubes for carrying off the vitiated air caused by combustion and the extractors for
delivering tlio same into the external air:

is the same as otherwise only omitting all parts relating to the warming of the air.
DESCRIPTION OF THE DRAWINGS

Having now described the nature of my invention and the manner in which
it may be carried into effect, in one of the dispositions of the same, as before
described but which may be varied according to circumstances and the details of
which therefore I do not confine myself to, I now proceed to state what I consider
novel in my said invention and therefore claim as secured to me by the Letters
Patent granted to me as follows, namely-
First In window ventilation the admission of an upward current of atmospheric
air, warmed or otherwise, in regulated quantity into a building or other structure
by means of a glazed vertical chamber formed on the inside of the plane of the
ordinary glazing of the window, or upon the outside of the same, or partially on
each side substantially as shewn and described.
Second In window ventilation by a vertical upward current of air, warmed or
otherwise, the application of an adjustable flap or outlet to regulate the quantity
and direction of the entering air substantially as shewn and described.
Third In window ventilation by a vertical upward current, the raising of the
temperature of the air before admission to a regulated extent by means of a
heating apparatus constructed and operating substantially as shewn and described.
Fourth. In conjunction with window ventilation by warmed atmospheric air, the
extraction and delivering into the external air of the vitiated air or products of
combustion, by means of the apparatus called an "Extractor" constructed and
operating substantially as shewn and described.
Fifth The combination of parts forming the window ventilator consisting of the
vertical chamber formed as described in first claim, with an adjustable flap or

page_text: outlet and with or without the apparatus for warming the entering air, also the
apparatus for extracting the vitiated air caused by combustion the whole
constructed and operating substantially as shown and described.
In witness whereof I the said Georgo Connell have hereunto set my hand and
