PROVISIONAL SPECIFICATION.
Improvements in and Apparatus for the Admission of Pure or Filtered
Air to Rooms and other places, or Apartments, and for Prevent-
ing the Admission of Dust and Dirt.
I, VERNON BUTTERWORTH RADCLIFFE, of 105 Westbourne Terrace, Hyde Park,
in the County of London, Gentleman, do hereby declare the nature of this
invention to be as follows:-
The object of my invention is to provide simple and effective means for the
admission of pure filtered air to rooms, and other places, while preventing the
admission of smuts, dust, and dirt of all kinds without having to change the
structural equipment of the rooms or other places to which my invention may be
applied.
According to my invention I provide a case or frame which may conveniently
assume the form of a long box, being in length the width or about the width
of the window sash, and in depth say about four inches, more or less; this casing
or box should be hinged on one side lengthwise, and on the other or opposite
lengthwise side be fitted with fastenings, say hooks and eyes, to hold the case
together when required.
The case before referred to has perforated sides, which may be conveniently
made of perforated zinc, or wire gauze, and in such manner that atmospheric
air may freely pass through same into the interior and out through the corres-
ponding perforated sheets on the opposite side. In the case and between the
perforations I place cotton wool, medicated or not as may be desired.
A case constructed and prepared as before described to be called "The Cliffe
Patent Ventilator," is for the purposes of my invention placed on the lower
window sill, and the sash frame brought down to rest on the end thereof; by
these means pure and filtered air is admitted to the apartment, to which the
apparatus is applied, while the wool arrests the admission to the apartment of
dust, dirt, or other extraneous matter or substance.
A cushion or pad should be fitted to the edge on which the window frame rests,
to obtain a tight joint.

Air to Rooms and other places, or Apartments, and for Preventing
the Admission of Dust and Dirt.
I, VERNON BUTTERWORTHI RADCLIFFE of 105 Westbourne Terrace, Hyde Park
in the County of London, Gentleman, 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:-
The object of my invention is to provide simple and effective means for the
admission of pure and filtered air to rooms, and other places, while preventing the
admission of smuts, dust, and dirt of all kinds without having to change the
structural equipment of the rooms or other places to which my invention may be
applied.
My invention will be readily understood by the following description having
reference to the accompanying drawings whereon Fig. 1 is a perspective view
of my improved apparatus for the admission of pure filtered air to rooms and other
places. Fig. 2 shews in elevation part of the interior of a sash frame window
with my apparatus applied thereto, the same being drawn to a smaller scale than
the previous figure. Fig. 3 is a cross section of the parts shewn at Fig. 2.
Similar letters of reference refer to like parts in the several Figures of the
drawings.
According to my invention I provide a case or frame which may conveniently
assume the form of a long box, being in length the width or about the width
of the window sash, and in depth say about four inches, more or less, this casing
or frame should be formed in two parts A and A¹ Fig. 1, and hinged at Bon
one side lengthwise, and on the other or opposite lengthwise side be fitted
with fastenings, say hooks and eyes such as C to hold the two parts A and A'
of the frame together when required.
The frame, A A' before referred to are provided with perforated sides D D
which may be conveniently made of perforated zinc, or wire gauze, and in such
manner that atmospheric air may freely pass through same into the. interior
and out through the corresponding perforated sheet on the opposite side. In
the frames A A and between the perforated sides D D, I place cotton wool. E,
Fig. 3, medicated or not, as may be desired.
A case constructed and prepared as before described to be called "The Cliffe
Patent Ventilator," is for the purposes of my invention placed on the lower
window sill F, see Figs. 2 and 3, and the sash frame G is brought down to rest
on the end thereof; by these means pure and filtered air is admitted to the apart-
ment to which the apparatus is applied while the wool E arrests the admission
to the apartment of dust, dirt, or other extraneous matter or substance.
A suitable cushion or pad H should be fitted to the edge on which the window
Frame G rests, to obtain a tight joint.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is:-
1. In supplying pure or filtered air to rooms and other places or apartments,
causing such air supply to pass through a case having perforated sides, and
through cotton wool (medicated or not) contained within the said case and between
the perforated sides thereof, the case being adapted to be placed between the
raised window sash, and the sill or sash frame, substantially as described.
2. The apparatus for the admission of pure or filtered air to rooms and other

page_text: places or apartments, composed of two rectangular frames, hinged together at
one edge, provided with fastening devices at the opposite edge, perforated zinc
or wire gauze within each frame, cotton wool, medicated or not, contained between
the hinged frames and between the perforated diaphragm contained thereby,
and a packing joint piece on the edge or edges of the same frames, the apparatus
being adapted to be placed between a raised window sash and the sill or sash
frame substantially as described and illustrated with reference to the accom-
panying drawings.
