Improvements in and connected with Ventilators.
I WILLIAM JAMES Fox of Ryefield Villas, Marple in the County of Chester,
Buyer, do hereby declare the nature of this invention to be as follows:-
My said invention relates to an improved ventilator or appliance for attaching
to window sashes or frames, which will allow the admission of air into any room
without creating an objectionable draught, at the same time it will disinfect or
purify the air so admitted and prevent the admission of dust, soot and other
impurities. Provision is also made for the exit of impure air from the rooms
in which my invention is applied.
My disinfecting ventilator is formed of a tube made either of a coarse open
textile material, or of perforated metal or cardboard or partially of the open
textile material in connection or combination with the perforated metal or card-
board. In the interior of the tube, I place cotton wool or other suitable filtering
material impregnated or charged with a disinfecting medium, such as potassic
permanganate, carbolic acid or other suitable disinfectant.
The ventilators can be so made that when charged with the disinfecting medium
they can either be suspended in front of the sashes top and bottom of the window,
by means of loops and suitable nails or hooks, or made to fit in between the top
and bottom of the sashes and window frames, by means of wood'or other suitable
blocks attached to their ends and placed within the grooves in which the sashes
run or slide, with suitable attachments to keep them in position. The tube or
ventilator for centre of window, will simply require to be placed on the meeting
rail of the sash and against the glass. For the purpose of attaching my
ventilators to any window, I propose to lower the top sash to such a distance
as may be required and either suspend my ventilator in front of the opening so
créated, or place it in such opening, as may be desirable. When attaching to the
bottom sash raise the sash and proceed as described for the top sash. My
improved disinfecting ventilator can be attached to any ordinary window, and by
mcans of suitable attachments can also be adapted to partially open casement
windows, or doors of rooms, and form also a means of keeping the door or casement
window open, whilst at the same time it will exclude draughts and act as a disin-
fecting medium, which is important if there is sickness in any other part of the
house. The appliance may be modified in. slight details, but, mainly I adhere to
the construction herein before set forth and described.

COMPLETE SPECIFICATION.
Improvements in and connected with Ventilators.
I WILLIAM JAMES Fox of Ryefield Villas Marple in the County of Chester,
Buyer do hereby declare the nature of this invention and in what manner: the:
0same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My said invention relates to improvements in and connected with ventilators for

page_text: attaching to window sashes or frames which allow of the admission of air into any
room without creating an objectionable draught, at the same time they disinfect or
purify the air so admitted and prevent the admission of dust soot and other
impurities. My invention also allows the exit of impure air from the rooms to
which the ventilators are applied.
My invention will be more readily understood by a reference to the annexed
sheet of drawings.
Figure I is an external view of an ordinary window with my improved
ventilators placed in position.
Figure 1 is the front elevation of one of the ventilators.
Figure 3 is an end view of same, and Figure 4 an alternative end elevation of
the ventilator used top and bottom of window, though I do not bind myself to these
two forms, but make the ventilators to any section found most convenient for each
individual case.
Figure 5 is the plan of the ventilator used for centre of window and is placed on
the meeting rail of the bottom sash and against the glass of the top sash, so as to
purify the air admitted at centre of window and keep out smuts and dirt. The
part marked B Figure 5 is the tube or box or ventilator, of which the portion
marked is recessed to fit against the bar of the top sash, and the parts marked c
are prepared to allow of the ends being placed within the grooves of the pulley
stiles of the sash frames. The forms shewn are general and would require adapting
to individual cases.
Figures 7 and 8 shew the method of adapting and fixing my improved ventilators
into windows specially prepared either in new or old buildings.
In Figures 1 and 2 A is a tube or box made either of a coarse open textile
material, or of perforated metal, wood, cardboard or other suitable material in
connection or partially of the open textile material in connection or combination
with the perforated metal, wood, cardboard or other suitable material. This tube
or box is formed round suitable blocks or ends made to the section or form required.
Upon these blocks or ends strips a of suitable material are fastened for the purpose
of attaching the tube or box to the frame of the window and when necessary stays
are placed within the tube at convenient distances from the ends to keep the
ventilators to their proper shape. In the interior of the tube A I place cotton
wool or other suitable filtering material, impregnated or charged with a disinfecting
medium such as potassic permanganate, carbolic acid or other suitable disinfectant.
For the purpose of attaching my improved ventilators to any window, I either
suspend them in front of the sashes top and bottom of the window by means of
suitable loups and hooks or nails, the said sashes being lowered and raised as
required or I place the ventilators in the openings made by lowering and raising
the sashes as shewn at A Figure 1. When placed between the sashes and the top
and bottom of the sash frames the upper and lower edges of the ventilators are
covered or partially covered with cotton wool, india rubber or the like yielding
material, so that when the sashes are pushed against the ventilators they will not
only be securely held in position but will also prevent the admission of air other
than through the filtering mediam of the ventilators and the ventilators are also
provided with suitable attachments to prevent them falling out when the sashes
are lowered or raised.
In
The tube or box or ventilator B, Figures 1 and 5 and D Figures 7 and 8 is
charged with a disinfecting or filtering medium in the same manner as A.
The
tube or box or ventilator B used for the centre of the window
padded on the side
next the glass and when used it is only necessary to place it on the meeting rail of
the bottom sash and against the glass in the top sash as shewn at B Figure 1.
new buildings or where it is desired to use my method of ventilation as a fixture
attachment to any windows; my tube or box made of suitable material, filled with
cotton wool or other filtering material and impregnated with a disinfectant or.
without can be fixed in at top or bottom or both top and. bottom of the window
thus preventing need of opening the window for ventilation as shewn in Figures 7

page_text: and 8 where D is the tube or box prepared in the form of a quadrant or other
portion of a circle and fixed to the sash or sash frame, E is a pane of glass framed
and working by means of binges on a cross bar of the sash so that the top edge
noves close to the underside of the ventilator D. By a suitable arrangement the
inoveable pane of glass can either be quite close or placed in any position required.
Figure 8 shews the pane of glass in position to admit the entrance or exit of air
through the ventilator D when opened to full extent. The ends of the arrangement
marked F can either be closed or made in the same manner as the top and so
provide an additional means of ventilation. My improved disinfecting ventilators
can by suitable attachments be adapted to partially open casement windows or
doors of rooms so as to allow of the door or casement window being kept open and
at the same time exclude draughts and act as a disinfector, which is important if
there is sickness in any part of a house. Figure 6 shews my improved ventilator
applied to doors or casement windows. The ventilator C is made sufficiently large
to cover the opening and is suspended in front of the same by means of a rod e or
other convenient method and kept in position by loops and hooks when required.
Where my ventilators are used in this manner, doors of sick rooms can be kept
open and the room not only supplied with pure air but any air passing from the sick
room to other parts of the house will be disinfected. It will be understood that
my invention may be applied to the walls of buildings as well as to the windows.
Having now particularly described and ascertained the nature of my said inven-
vention and in what manner the same is to be performed I declare that what I
claim is
1st. The combination of cotton wool or other filtering material placed inside, or
both inside and outside a tube or box so as to exclude dust, smut and excessive
draught when applied in the manner hereinbefore set forth and described.
2nd. The use of a disinfecting medium in combination with the cotton wool or
or other filtering material for the purpose of purifying the air admitted into or
issuing from the rooms to which my ventilators are applied whether to doors,
windows or walls, in the manner hereinbefore set forth and described.
Dated this 6th November 1895.
