WINDOW VENTILATOR
Charles A. Anderson, New Rochelle, N. Y., as
signor to The Gotham Pressed Steel Corpora
tion, New York, N. Y., a corporation of New
York
Application August 11,
'7 Claims.
My invention relates to window ventilators and
has particular reference to ventilating de?ectors
or shields placed in the lower portions of win
dow's.
Window ventilators of this type usually have
de?ectors made of glass plates held in place
by end brackets fastened to window frames.
When ?tting a ventilator to a window, the glass
plate must be therefore cut to the exact width
it) between the brackets, this width more or less
varying for different windows. Such an opera
tion is highly objectionable, however, rendering
the installation di?‘icult and requiring services of
an expert glass cutter. In order to avoid this
15 di?iculty, two glass plates are sometimes used,
telescopically sliding side by side. This ar
rangement is also objectionable, however, two
panes of glass being more expensive and requir
ing special adjustable braces or rods on top and
20 bottom of the plates, and being less satisfactory
from the standpoint of appearance than a single
covering the holders but also serving as clamps
to hold the sides of the holders together, the
holders being preferably made in the form of
.p-shaped pieces of sheet metal.
My invention is more fully described in the
accompanying speci?cation and drawing in
which—'

attached to an ordinary window.

I have found, however, that it is possible to
make horizontally adjustable ventilators, using
25 glass plates of a standardized length and provid
ing adjustment in the end brackets. Windows in
ordinary houses vary in width, as a rule, by a
few inches only, say between 36 and 40 inches.
By making the glass plates 38 inches long, for
30 instance, and the end brackets 3 or 4 inches
deep, I can provide a ventilator readily attach
able to any ordinary window. An object of my
invention is therefore to provide a ventilator of
a standardized construction which can be at
35 tached to any ordinary window by merely screw
ing or nailing the end brackets to the window
frame.
Another object of my invention is to provide
end brackets with detachable holders for the
By making the holders detachable
not only their manufacturing is simpli?ed, but
their handling for shipmentis facilitated, the
knocked down parts occupying much less space
than the assembled brackets.
Another object of my invention is to provide
means for retaining the glass plate in the end
holders in a ?xed position after the brackets have
been fastened to a window frame. For this pur
pose I provide adjustable blocks in the holders
resting against the ends of the glass plate, or
adjustable screws or plugs ?tted in slots or holes
in the holders.
Still another object of my invention is to pro
vide sliding caps for the upper portions of the

My window ventilator consists of end brackets 25
shown in- detail in Fig. 2 which may be formed
of two pieces i and 2 each pivoted together at 3
and telescopically adjustable to different angles
of opening as described'in my Patent No.2,016,764.
A lug 4 on one piece and a hook 5 on the other 30
prevent the pieces from becoming entirely sepa
rated.
The outer piece or sector 2 has a ?ange
6 with rectangular apertures ‘I, the inner piece
l having holes 8 for attaching the brackets, which
are right and left, to the inner sides of a window 35
frame 9 by screws H3. The apertures ‘l are en
gaged by resilient hooks ll formed in U-shaped
holders l2 for a glass plate l3. The holders are
made of sheet metal and the hooks l l are stamped
out to register with the apertures 1. Thus the 40
brackets and the holders can be easily assembled
together or taken apart to be packed for ship
ment. The sides of the holders are spaced apart
so as to provide room for the ends of the plate
[3, the width of the sides of the holders being 45
su?icient to allow for ordinary variations in the
width of the windows. I have found that holders
3 or 4 inches wide can be used with a large num
ber of windows, having usually from 36 to 40
inches in width, the glass plate being about 38 50
inches long. In order to prevent longitudinal
shifting of the plate after its assembly, I provide
spacing blocks M in the holders resting against
the ends of the plate [3. These blocks are pref
erably made of wood or similar material which 55
