Improvements in Convertible Window Sashes.
We, WILLIAM RICHARD MARTIN of 22 Ferncliffe Road, Dalston, Engineer,
HENRY HONYCHURCH of Seething House, 61 Great Tower Street, London,
Custom House Agent, and ALFRED SCRAFIELD MORLING Seething House
61 Great Tower Street, London, Custom House Agent, 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:-
This invention renders hanging window sashes capable of being turned inwards
so that cleaning or repairs can be done by a person standing within the room.
This is effected by the simple and inexpensive arrangement hereafter described,
which consists of (1) a mode of quickly removing the side beads (2) unhooking
the cord of the sashweight on one or both sides (3) sliding the sash up or down
as the case may be, to clear the head or sill beads, upon vertical bars or tubes
fixed for the purpose on one side of the sash; such bars passing through the sash
and (4) swinging the sash inwards by means of the hinge action derived from their
being pivotted on the vertical bars or tubes.
We will now describe our invention with reference to the accompanying
drawings in which
Fig. 1 shews an elevation of a pair of convertible hanging sashes.
Figure 2 shews a side elevation of the window race shewing the position of the
vertical bars, and their fastenings.
Fig. 3 shews a plan of the nuts for fixing the bars secured in position d, d, e, e.
a, a, are the two inner beads hinged, and shewn open. When closed they are
secured by sliding bolts at p, p.
b, b, are two iron bars or tubes fastened by means of screwed nuts at d, d, e, e,
and secured there. c, c, and f, f, are metal fittings at the top and bottom corners
of the sashes through which the bars pass, and thus form permanent hinges.
The rabbets in sash stiles having been deepened and fitted to receive the bars
and sash lines.
m, is a point at which in high windows a division in the parting bead could be
made if so desired, leaving the upper part of the bead in position, and the lower
part movable. 9, is a small plate through which passes a suitable pin across the
casing to support the balance weights when the cord is unhooked to enable the
sashes to be opened, thus leaving the hands free from any difficulty with the weights
while engaged in opening the sash. ', is a similar fitting to g, but will not be
required in the operation of opening the window, as the lines on that side remain
attached, but may be useful when required to remove the sashes entirely.
i, i, are hooks fitted to sash lines to take cross bars at k, k¹, similar hooks connect
the sash lines on the hinge side of the sashes.
The operation of opening the windows is as follows. Turn back the inner
beads a, a, raise the lower sash just out of the lower bead, insert pin at
g, a distance
to catch weight of this sash only, then draw the sash out at the side and unhook
the line at k. It will then be free to swing full open. Next draw down the upper
ash, then remove the parting beads, push the pin at g, right home to catch the
other weight, and proceed as in the case of the lower sash. It may be observed
hat in the operation above described no tools are required, and that there are no
crews to remove and replace, so that the operation can be performed by any
inskilled person.
In making new sashes it is recommended that a little extra scantling in sash
tiles be allowed, giving more accommodation in the rabbets for stout bars where
ecessary.

page_text: The vertical bars will of course vary in strength according to size and weight of
the sashes.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The method of constructing hanging window sashes so as to render them
convertible into hinged sashes and capable of being turned inwards by means of
permanent hinges formed by pivot bars and with the aid of detachable sash lines
and other appliances as herein described and set forth.
2. In a window with convertible sashes, the general arrangement, construction,
and combination of the several and respective parts together forming the
improvements substantially as herein described and set forth.
Dated this 1st day of May 1891.
