Improvements in Ventilating Sashes.
I, WILLIAM ANDERSON of the firm of John Anderson and Son, 154 Bothwell Street,
in the City of Glasgow, Blacksmiths, do hereby declare the nature of this invention to
be as follows:-
In ventilating sashes as heretofore made an objection pertains that in opening and
closing, the sash by coming in contact with the glass in the side quadrants is liable to
fracture it and one of the objects of the invention is to overcome this objection.
In carrying out the invention the side quadrants between which the sash works are
made of iron and so arranged that the web of the T is between the side of the sash
and the glass which is fixed in the quadrant on the other side of the web by putty or
any other usual mode.
On the upper side of the sash a bracket is secured carrying in an upwardly projecting
arm or eye a pulley or block and on the sash framing another similar bracket is fixed
also carrying a pulley or block, the sash being locked to the framing when the window
is closed by a spring bolt which is carried in a sleeve on the bracket on the sash and
which has a sneck or projecting end entering a hole in the bracket on the frame or
other equivalent means of locking may be adopted.
The operating cord is knotted or has a knob at one end and it is passed through an
eye or hole in the bracket on the sash thence under and round the pulley on the sash
frame and over the pulley on the sash itself from whence the cord hangs downward
in a long loop the other end of it being connected to an eye or ring on the spring
bolt.
When it is desired to open the sash for purposes of ventilation, the end of the cord
connected to the spring bolt is pulled so as to free the bolt from the slot in the bracket
on the sash frame and the sash then swings open of its own accord.

I, WILLIAM ANDERSON of the firm of John Anderson and Son, 154 Bothwell Street,
in the City of Glasgow, Blacksmiths, 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 :-
In ventilating sashes as heretofore constructed an objection pertains that in opening
and closing, the sash-by coming in contact with the glass in the side quadrants-is
liable to fracture it and one of the objects of the Invention is to overcome this
objection.
On the accompanying drawings-figure 1 is a front elevation and figure 2 a vertical
section at right angles to figure 1 of a ventilating sash constructed in accordance with
my said Invention.
In carrying out the Invention the side quadrants a between which the sash b works
are, as more particularly indicated at figure 3 which is a cross section on the line X, 20
figure 2, made of T iron and so arranged that the web of the T is between the sides
or ends of the sash and the glass, the latter being fixed in the quadrant on the other
side of the web by putty or any other usual mode.
At the upper end of the sash a bracket c is secured carrying in an uptwardly
projecting arm or eye d a pulley or block e and on the sash framing f another similar
bracket g is fixed also carrying a pulley or block h, the sash being locked to the framing
when the window is closed by a bolt which is carried in a sleeve on the bracket on
the sash b. The bolt has a sneck or projecting end which enters a hole j in the bracket,
on the frame f. In conjunction with the bolt a weight is provided the weight being
centred on the bracket c and so connected to the bolt that its tendency is to shoot the
sneck end of it outwards, or instead of the weight the bolt may have a spring in
connection with it or other equivalent means of locking may be adopted.
The operating cord is knotted or has a knob at one end and it is passed through an
eye or hole in the bracket c thence under and round the pulley h and over the pulley e
from whence the cord hangs downward in a long loop the other end of it being connected
to an eye or ring on the bolt i.
When it is desired to open the sash for purposes of ventilation, the end of the cord
connected to the bolt is pulled so as to free the bolt from the slot j in the bracket g and
the sash then swings open of its own accord.
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 :
1. As an improvement in ventilating sashes so constructing the side quadrants that

page_text: a web is interposed between the glass in the quadrants and the sides or ends of the
sash substantially as and for the purpose set forth with reference to the drawings
annexed.
2. The general arrangement and combination of parts constituting the improved
ventilating sash hereinbefore described and shewn on the accompanying drawings.
Dated this Fourth day of February 1888.
