Improvements in a contou
I, CHARLES WILLIAM BARRON of 83 Would have Street, South Shields, in the
County of Durham, builder 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 relates to Improvements in and connected with Window Sashes, the
improvements consisting in an arrangement of compound sash whereby the present
dangerous system of cleaning the outsides of windows by the operator sitting on tho
window cill for this purpose is altogether abolished.
For the purposes of this description I will now refer to the accompanying drawings
illustrative of my invention, in which Fig. 1 represents a sectional plan through a
window sash framing constructed according to my invention, Fig. 2 shows an eleva-
tion of sash and slide with window lining removed and Fig. 3 a detail more
particularly hereinafter referred to.
A is the window lining, B the backing, C. C. are the pulley sash stiles, D D the
sash pullies and E E E E the sash weights. F is the sash frame hinged at F¹ to tho
sliding piece F to which the sash weight cord or chain is attached, the vertical
movements of the sash F and sliding picco F being thus rendered identical and con-
temporaneous. F is also a sliding picce and under ordinary conditions the window
sash F is connected to F3 by the slide bolt F. When the slide F³ is connected by
bolt F to sash F the two slides F2, F's and window sash F form -substantially one
piece and the sash weights which are connected to sliding pieces F, F' over pullies D
are designed to exactly balance the weight of the combined parts F, F, F³ with their
usual fittings and adjuncts. As just described the window appears to work under
similar conditions to ordinary windows, but when it is desirable to clean the outside
of the window the advantages of my invention become apparent. In order to effect
the latter purpose, the operator has only to withdraw the slide bolt F, the immediate
effect of which is to put the whole weight of sash weight E₁ onto slide F³ and
as the piece works in a suitable guide path, formed by the T-piece H, lining A
and pulley stile C it is immediately pulled up till its lower end is above the top of

page_text: the top window sash bar. The window can then be opened inwards as shown in
dotted lines in the drawings and its external surface can be cleaned at leisure without
risk to the operator.
The outer window sash is arranged to be worked in precisely the same way, its
slide being hinged to the sash frame F and its independent slide F³ is worked either
as part or independently of the sash F exactly as already described.
It will be seen that either the inner or outer window is when attached to its slides
in equilbrio through the medium of the sash weights and that the withdrawal of
bolt F at once permits slide F³ to fly upwards thus removing all obstructions or
hindrances from the free opening of the window inwards. Further I attach light
chains or cords F8 to the upper ends of the sliding pieces F3 which are for the purpose
of readily drawing down the slides against the force of the sash weights for connecting
the slides to the sashes F by bolt F4 after cleaning or for other purposes.
1 further provide means for preventing the window going to the bottom of its casing
when requiring to be opened, and I effect this object by having a bolt such as Fo
working in a suitable groove or bed contiguous to the pulley-stile bottom so that when
the window requires to be opened inwards it is only necessary to lift the window.a
little, then insert the bolt F, lower the window again, and as it rests on the bolt,
the bottom edge of window is clear of the beading F.
It will be seen that this arrangement is necessary for the purpose described as well
as for ensuring a weather-tight joint when the window is closed.
The several parts of my invention may be constructed of wood, iron, brass, or any
other known suitable material.
Having now. particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed I declare that what
1 claim is:
(1) The use in combination with the sashes of window frames of the sliding
pieces F, F, and bolt 1 or its equivalent all arranged and operating substantially
in the manner and for the purposes herein before described and illustrated in the
annexed drawings.
(2) The use in combination with the parts named and claimed in claim 1 of the
cords or chains F operating substantially as and for the purposes hereinbefore
described and illustrated.
