I, MARIAN CHArlotte Pincoffs, of The Cottage, Minehead, in the County
of Somerset, Spinster, do hereby declare the nature of this invention to be as
follows:-
"
My invention refers to means or apparatus as hereafter described for ventilating
rooms and other places, and the invention is particularly applicable for use in sick-
rooms, hospitals, board schools, and the like, where fresh air is required, or it is
very advisable it should be admitted without a draught or current being produced.
I will describe my invention as applied to such casements or windows as are

hinged to the frames, commonly known as "French casements.'
to my invention I provide a framing extending out at the vertical side of the sash
frame opposite to the hinges from the said sash frame, and on the outside of same,
say from two to six inches, and at the top and bottom of this frame I connect
triangular frames extending from the aforesaid vertical frame to the hinge side of
the sash frame.
In this framework, which is a skeleton frame, I insert perforated tin, wire
gauze, or fabric, or any other porous weather-proof material; thus when the
window is opened in the ordinary way towards the outside, to the extent of the
outer vertical frame, it will be evident that air is free to travel and pass through
the gauze or fabric into the room while the window frame fitting the framework
before described prevents air entering except through such gauze or fabric.
Sometimes the aforesaid skeleton frame may be made separate from the window
frame and fitted thereto when it is required to be used as a ventilator, being then

either case may be regulated by a sliding shutter or the like, put on, or taken off
at will, in the frame which is not fixed, and in the one to be permanently fixed to
the outside of the window, some arrangement of the same kind may be adopted.
The amount of air admitted to the room may also be regulated by a blind which
can be raised or lowered so as to cover or expose the perforations according to the
amount of air to be admitted. This blind may be a roller blind worked by spring
arrangement or otherwise as most convenient.

COMPLETE SPECIFICATION.
Improvements in Ventilating Appliances for Windows and
the like.
I, MARIAN CHARLOTTE PINCOFFS, of The Cottage, Minehead in the County
of Somerset, Spinster 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 refers to means or apparatus as hereafter described for ventilating
rooms and other places, and the invention is particularly applicable for use in sick
rooms, hospitals, board schools, and the like, where fresh air is required, or it is
very advisable it should be admitted without a draught, or current being produced.
I will describe my invention as applied to such casements or windows as are

page_text: hinged to the frames, commonly known as "French casements," and my said
invention will be readily understood by reference to the accompanying drawing,
Figs. 1 and 2 thereon being perspective views of the apparatus, shewn detached
from the caseinents, and
Fig. 3 is a horizontal section of a casement with my apparatus applied thereto.
Similar letters of reference indicate like parts in the several figures.
According to my invention I provide a framing A, projecting vertically at the
side of the window frame B, opposite to the hinges C', of the window C, the said
frame A extending outwards or inwards according to the direction in which the
window opens say from two to six inches. At the top and bottom of this frame A,
I connect triangular frames D E, extending from the aforesaid vertical frame A, to
the hinge side of the sash frame B.
In this framework A D E, which is a skeleton frame, as shewn, I insert perforated
tin, wire gauze, or fabric, or any other porous weather-proof material F; thus
when the window is opened in the ordinary way say as shewn at Fig. 3, to the
extent of the vertical frame A, it will be evident that air is free to travel and pass
through the gauze or fabric F, into the room, while the window frame C fitting
against the framework A D E before described, prevents air entering except
through such gauze or fabric F, a suitable packing J, to act as a draught
preventer, being fixed on the edge of the frame A, to interpose between the
window C and the frame A.
The aforesaid skeleton frame may be made separate from the window casement
and adjusted thereto, when it is required to be used as a ventilator, it being put in
and taken out from the inside of the room. The amount of ventilation, in either
case, may be regulated by a sliding shutter G or the like, and such a shutter G is
clearly shown at Fig. 2, it being carried in upper and lower guides G¹ G² on the
frame A. This shutter G may be readily moved or adjusted into desired position
by a person standing in the room, and be utilized for entirely closing, opening, or
partially opening the ventilating device at will.
In some cases the frame may be a fixture, especially in newly constructed window
frames, but otherwise is preferably constructed and fitted as described.
The amount of air admitted to the room may also be regulated by a blind H
(see Fig. 1) which can be raised or lowered so as to cover or expose the perforations
according to the amount of air to be admitted. This blind may be a roller blind
worked by spring arrangement or otherwise as most convenient and may also be
fitted in combination with the shutter G.
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:
First. In ventilating appliances for windows and the like, a vertical frame A
with horizontal triangular top and bottom parts DE, having apertures therein
covered with porons material F for ventilation, the aforesaid frame being adapted
to adjustably take between the opened sash of a hinged window and its casement
all substantially as and for the purposes herein before described.
Second. The general arrangement and combination of parts forming my improve-
ments in ventilating appliances for windows and the like, composed of a
framework A D E, having ventilating spaces covered with porous material F,
and adapted to take between the hinged window sash and its casement, the said
frame A D E, being provided with suitable draught packing J and connections
and fittings, and with a sliding shutter G or a blind H or both in combination, to
regulate the admittance of air all constructed and acting substantially as and for
the purposes described and illustrated with reference to the accompanying drawings.
Dated this 11th day of December 1893.
