page_text: Improvements relating to Pivotted Window Sashes.
I, JOSEPH MAKINSON, of 20, Cowley Hill Lane, St. Helens, Lancashire, Builder,
do hereby declare the nature of this invention to be as follows:-
This invention relates to means whereby windows may be readily opened or
removed for the purposes of ventilation or cleaning.
I so construct and arrange a window sash that it may be revolved upon a vertical
axis running centrally through the sash from top to bottom. To the top and
bottom bars of the sash I attach pintles or trunnions which rest in sockets provided
at the top and at the bottom of the frame. Such sockets by preference consist of
a bracket provided with a hinged cleat, which is secured by a screwed stud and
when opened allows of the window being readily removed from its frame. The
vertical bars of the sash and frame are rebated so as to make a weather tight joint,
and to make the top and bottom sash bars weather tight I may provide projecting
weather boards. By preference, however, I make the lower bar weather tight by
means of a removeable lath which rests in a groove in the lower bar of the frame,
within the window, and which is removed when it is desired to open the window, the
upper bar only being protected by a weather board which projects from the frame.
As a means of keeping the window open at any desired angle, I attach to the
lower bar of the frame a perforated quadrant, into which drops a hook or catch
carried by the sash; and as a means of securing the window when closed, I provide
each side of the sash with a pivotted catch which enters an aperture in the frame.
It will be seen that the window above described may be readily turned outside-in
for cleaning purposes, or taken out of the frame.

statement:-
This invention relates to means whereby windows may be readily opened or
removed for the purposes of ventilation or cleaning.
In the drawing hereto annexed Figure 1 is a vertical section and Figure 2 is a
horizontal section, illustrating my improved means of pivotting window sashes.
Figure 3 is a front elevation of the lower sash-bar.
The window sash illustrated in the drawing is arranged to revolve upon a vertical
axis which consists of upper and lower pintles or trunions a and b. The upper
trunion a is screwed to the upper bare of the sash, and revolves in a socket d
screwed to the window frame. The lower trunion b is screwed to the lower bar
of the window frame, and works in a hinged socket fixed in the lower sash bar e.
Such socket consists of a bracket f and a hinged cleat g. The cleat g is secured
by a screwed stud h and when opened allows of the window sash being readily
removed from its frame. Thus by removing the single screw the cleat may be
turned back and the sash released. The vertical bars i and k of the sash are rebated
and abut against ribs and m attached to the window frame, so as to make a
weather tight joint. To render the upper and lower sash bars weather tight,
I provide them with sliding laths n and o, which enter grooves in the window frame
and which are removed from their grooves by the finger rings p, when it is desired
to open the window. The lower bar e also possesses a weathering q.
The upper
bar may be further protected by weathering the window frame.

As a means of keeping the window open at any desired angle, I attach to the
window frame a perforated sector r, into which drops a catch s, hinged to the
cleat g; and as a means of securing the sash when closed, I provide one or both
side-bars thereof with a latch t, which enters an aperture in the frame.
It will be seen that a window sash pivotted in the manner herein described
is very easily opened and closed, or turned outside-in for cleaning purposes, or may
be removed bodily from the frame.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The improved means of pivotting window sashes, whereby they may be readily
opened and closed, turned outside-in or removed from their frames, substantially
as herein described and illustrated in the accompanying drawing.
2. The improved socket for a pivotted window sash trunion, consisting of a fixed
portion f and a hinged cleat g, whereby the sash may be readily unshipped as
described.
3. The combination with the bracket f and hinged cleat g, of a hooked catch s,
arranged to enter a perforated sector r for the purpose of securing the sash at any
desired angle.
4. The employment, upon pivotted window sashes, of sliding laths such as n
and o, entering grooves in the window frame, for the purpose of rendering such
sashes weathertight, substantially as described.
