page_text: I, WILLIAM STEPHENS, of Old Ford, Wey Bridge, Hereford, Gentleman, do
hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in window ventilators, the object. being
to provide a simple method and means of ventilating rooms, passages and the like
through the window.
The method I employ is capable of being easily and cheaply applied to any
ordinary window, and allows the room, passage or the like to be sufficiently ven-
tilated without draught, while the ventilator may be opened or shut at any time as
required by lowering or raising the window sash, and I further provide a fastening
device for firmly securing the sash in either position, in such a manner as to
prevent rattling, at the same time rendering it practically impossible for the
window to be opened from the outside.
In carrying my invention into practical effect, I provide a light, preferably
metal, frame, of sufficient depth and of a length corresponding to the width of
the window sash, the thickness of such frame being equal to or less than that of
the parting bead, and I cut away from the top of each parting bead a part corre
sponding to the depth of the said frame, so as to allow of the latter being fitted
into the top of the window in such a manner that the sashes may freely pass
same, and this frame is filled with wire gauze or suitable open metal work for the
admission of air.
When it is required to ventilate the room, passage or the like, the top sash is
lowered for a sufficient distance which allows of the air passing through the ven-
tilating device without causing a draught, while upon closing the window sash the
ventilation is stopped.
In order to allow of the ventilating device being utilized when the window is
closed, the top rail of the window sash may be furnished or formed with a longi-
tudinal opening of sufficient size, normally covered by means of a suitable slide,
which can be drawn back for the purpose of admitting air into the room when
required.
To secure the window sashes for the purpose of locking the window in either
the open or closed position, I provide a fastening device comprising a metal screw
passing through a suitable screw threaded sleeve or body furnished with a base
plate or extension by means of which it may be secured to the lower window sash,
while I further provide a receiving plate designed to be screwed into position
upon the upper sash and furnished with two or more internally screw threaded
holes, perforations or sockets, into which the extremity of the aforesaid screw

hole, perforation or socket being approximately equal to the depth of the ven-
tilating device.

I, WILLIAM STEPHENS, of Old Ford, Wey Bridge, Hereford, 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;
..
My invention relates to improvements in window ventilators, the object being
to provide a simple method and means of ventilating rooms, passages and the like,
through the window.
The method I employ is capable of being easily and cheaply applied to any
ordinary window, and allows the room, passage or the like to be efficiently ven-
tilated without draught, while the ventilator may be opened or shut at any time as
required by lowering or raising the window sash, and I further provide a fastening
device for firmly securing the sash in either position, in such a manner as to
prevent rattling, at the same time rendering it practically impossible for the
window to be opened from the outside.
In carrying my invention into practical effect, I provide a light preferably
metal frame of sufficient depth and of a length corresponding to the width of
the window sash, the thickness of such frame being equal to or less than that of
the parting bead, and I cut away from the top of each parting bead a part corre
sponding to the depth of the said frame, so as to allow of the latter being fitted
into the top of the window in such a manner that the sashes may freely pass
same and this frame is filled with wire gauze or suitable open metal work for the
admission of air.
When it is required to ventilate the room, passage or the like, the top sash is
lowered for a sufficient distance which allows of the air passing through the ven-
tilating device without causing a draught, while upon closing the window sash the
ventilation is stopped.
In order to allow of the ventilating device being utilized when the window is
closed, the top rail of the window sash may be furnished or formed with a longi-
tudinal opening of sufficient size, normally covered by means of a suitable slide,
which can be drawn back for the purpose of admitting air into the room when
required.
To secure the window sashes for the purpose of locking the window in either
the open or closed position, I provide a fastening device comprising a suitable
metal screw passing through a screw threaded body or sleeve furnished with a base
plate and extension by means of which it may be secured to the lower window
sash, while I further provide a receiving plate designed to be screwed in position
upon the upper sash and furnished with two or more screw-threaded holes, or per-
forations or sockets into which the extremity of the aforesaid screw takes for
securely fastening the window, the distance between the top and bottom holes, per-

page_text: forations or sockets, being approximately equal to the depth of the ventilating
device.
In order that my invention may be more fully understood, I will now proceed
to describe same with reference to the accompanying drawings in which
Fig. 1 is an elevation of a window fitted with my improved ventilating device.
Figs. 2 and 3 are details illustrating the parts of the ventilating device which
may be brought into use when the upper sash is closed.
Fig. 4 is a side elevation of the fastening employed.
Fig. 5 being a similar view of the plate used in connection therewith.
According to this invention and as shown in the drawings, the ventilating frame
or screen a (Fig. 1) is arranged at the top of the window, the parting beads at
each side being cut away so as to accommodate same, the thickness of the said
frame being equal to or less than the thickness of the said parting beads.
In order to ventilate the room, passage or the like, it is only necessary to lower
the top sash for a sufficient distance as shown (Fig. 1) when the air can pass
through the ventilating screen a without causing a draught.
In order to allow of the ventilating device being employed when the window is
closed, the top rail g of the upper sash a may be furnished with a longitudinal
opening of sufficient size normally covered or closed by means of a suitable slide
that can be drawn back for the purpose of admitting air as hereinbefore described,
or as shown in Figs. 2 and 3, longitudinal plates c and d are secured to the inner
and outer surfaces of the top rail g of the sash b, while behind the front plate
a slide f is arranged. A series of holes or perforations h are bored through the
plates c and d and also through the substance of the to rail g, a similar number
of holes or perforations being formed in the slide f, so that upon bringing the
said slide from right to left the holes in the said slide may be brought to coincide
with those of the top rail of the sash.

The fastening device I prefer to employ in connection with windows fitted with
my improved ventilating device consists of a metal screw m passing through
suitable screw threaded body of sleeve extending from a base plate o formed
integrally with a right angled extension by means of which it may readily be
secured in position upon the top rail of the lower sash, while I further provide a
receiving plate designed to be screwed in position upon the side of the upper
sash and furnished with two or more screw-threaded holes, perforations or
sockets such as the top and bottom holes being arranged a distance apart corre-
sponding approximately to the width of the ventilating frame or screen a.
By means of this fastening device the window may be secured in either the
open or closed position the fastening device being arranged at one side, or, where
preferred, two fastening devices may be employed and fixed one at each side of the
window.
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. The arrangement of a ventilating frame or sereen such as a in the upper
part of a window frame substantially in the manner herein described and shown
with reference to the accompanying drawings and for the purposes specified.
2/. The combination with the specific arrangement of a ventilating frame or
screen such as above claimed, of a suitable slide such as arranged in the top
rail of the upper sash b and designed to normally close an opening or series of
openings or perforations in the said top rail, substantially as herein described and
shown with reference to Figs. 2 and 3 of the accompanying drawings, and for the
purposes specified.
37. The combination with the specific arrangement of a ventilating frame or
sereen such as above claimed, of a fastening device comprising a screw m passing
through screw threaded tubular body or sleeve such as n and furnished with a
base plate o and extension by means of which it may be secured in place; and a

page_text: plate such as furnished with two screw threaded holes, perforations or sockets
such as q' formed a distance apart corresponding approximately to the depth of the
ventilating frame or screen a, substantially as herein described and shown with
reference to the accompanying drawings, and for the purposes specified.
