An Improved Wall Ventilator.
Mrs. ESTHER BALLARD 15 Russell Chambers Bury Street London W.C.
no occupation do hereby declare the nature of this invention to be as follows:-
For ball or public rooms, also dining drawing bedrooms, staircases or over doors,
is elegant, simple and easy to adjust, and is the most hygienic luxury extant; it is
composed of two sections of galvanized iron tube, the end of the lower one is per-
forated, and the upper one has a damper, and on the top is firmly arranged a
portable shelf of wood, also supplied with ample perforation this is draped with
elegant passmentrie or leather, so deep as completely to conceal the upper
section, which is inside the room, and it is studded with brass or gilt studds.
The latter is firmly secured to the wall by slight ironwork, while the lower
section is laid in the brickwork with cement; it can be made to any dimentions
of diameter, and will be found invaluable for over doors in bedrooms, where the
ventilating apparatus can be arranged by a cord on either side-one for open,
and one for shut, passing over a small pulley wheel at the top of the door frame
on each side, and fastened round a cleat hook. When fixed a reaching distance,
it is secured by fixed attachments. When not desired as a ventilator is capable of
supporting a massive ornament, or vase, and is altogether unique as an invention
of modern utility, and beauty.

COMPLETE SPECIFICATION.
An Improved Wall Ventilator.
1, ESTHER BALLARD, of 15 Russell Chambers, Bury Street, in the County
of London, Gentlewoman, 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 an improved wall ventilator for private or public
rooms, passages, staircases or over doors and the like.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1 is a front elevation of the ventilator with the bracket in section and broken
off for convenience ;
Fig. 2, is a view of the bracket with the ornamental hangings covering the
ventilator;
Fig. 3, is a plan of the top of the ventilator with a dotted line to denote the
inside wall line or face.
e,
This invention is composed of two sections of galvanized iron tube to form an
elbow the end of the lower section is provided with a perforated plate t and
the cover r connected by a chains as in Fig. 3. The upper part of the elbow e has
a damper p fixed to a rocking bar f with suitable stops and u, the aforesaid
damper p is kept closed by the action of a weight m attached to one of the of
the rocking bar f by an adjustable hook 1. On the other eye of the rocking
bar fI fix a cord n for the purpose of opening the damper p by pulling the said
cord n.
In the front as in Fig. 1 I erect two hinged doors with fastenings j
and behind these said doors h I fix perforated plates k as shewn on one side of
eyes

page_text: the elbow in dotted lines and circles. The aforesaid elbow may be fixed to any
part of a room by a curved bar y secured to hold fasts or in any other suitable
manner. On the top of the elbow e 1 fix two stud pins d d and on these said
stud pins I fit a bracket a with a circular opening c, this opening being covered
by a perforated metal plate b; the aforesaid bracket a may be of any convenient
shape and ornamented with hangings g of any degree of elaboration, so deep as to
completely conceal the upper section of the elbow e which is inside a room as in
Fig. 2. The lower section of the elbow e is laid in the brickwork with cement, or
in wood work by any suitable fastenings.
り
A cord may be arranged on either side of the rocking bar fone for to open, and
one to shut the damper p by passing the cords over pulleys fixed in any convenient
positions and fastened round a cleat hook. When fixed at a reaching distance
it may be secured by fixed attachments, and if it is desired the top or bracket a
is capable of supporting a massive ornament, figure or vase.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In a ventilator, the combination of the elbow e damper p rocking barf stops o
and u, with doors h perforated plates b, and k, set pins d with bracket a, cord n
book and weight; the said bracket being covered with hangings to conceal the
apparatus, substantially as herein described and according to the accompanying
drawing.
