page_text: 1, SAMUEL BASTOW, of New Dock Saw Mills, Chadwick Street, Leeds, in the
County of York, Timber Merchant, do hereby declare the nature of this invention
to be as follows:-
-
The object of my invention is to construct pivotted windows so as to be weather-
proof, as well as to facilitate cleaning from inside, and to be able to lock the
same when open or partially open.
On the frames of the sashes at each side around the pivot I fix a wood or other
disc, which discs fit into corresponding recesses in the pulley stiles of the window
so as to break the joint, the cut away part on inner side of the stile being filled
in with a separate piece of wood. A double rebate is fixed on the frames for the
window to bed against at the top halves, and upon the sash stiles at the bottom
halves.
By unscrewing the centre pivots the windows may be taken out from the inside
when required.
On the discs may be thumb screws to engage with striking plates on the stiles
to secure the windows when open at any required angle.

I, SAMUEL BASTOW, of New Dock Saw Mills, Chadwick Street, Leeds, in the
County of York, Timber Merchant, 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;-
:-
The object of my invention is to construct pivotted windows, having either
'single or double sashes, in such a manner as to be weatherproof and easily cleaned

page_text: required position, either open, partially open, or closed.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation of a double sash window with my improvements
applied.
Fig. 2 is an end elevation of same in section.
Fig. 3 is an enlarged cross section at a a of one side of the window.
Fig. 4 is a cross section of same at b b.
Fig. 5 is a cross section of same at c c.
In carrying out my invention I employ at each side of the sash a wood or other
disc A, which fits loosely into a circular recess in the pulley stile (or pivot stile) D,
so as to revolve therein as the sash is opened.
The sash is preferably rebated into the said discs A, so keeping them in position
in the recesses in the pulley stiles D; or screws C may also be employed to fix the
sash stile B to the disc.
The said disc A being recessed into the pulley stile D breaks the side joint
between sash and frame at the middle of the sash. The side joints at the top and
bottom of the sash are broken by means of double rebates E F fixed to the pulley
stile D for the sash to bed against, the rebate E for the part of the sash above
the disc being outside the sash, and the rebate F for the part below the disc A
being inside the sash. The vertical joints of the window are thus made con-
pletely weatherproof.
False rebates G G are fixed to the sash stile B opposite the said rebates E F,
to give a symmetrical appearance to the sash.
The double rebate E outside the sash is carried at H (Fig. 2) across the head of
the frame; the frame sill K and meeting rails L L are also double rebated, so
as to ensure entirely weather-proof horizontal joints.
The rebates E F and the false rebates G are preferably tapered or cut away at
the ends adjacent to the discs A, so as not to restrict the opening of the sash to
a convenient angle for cleaning from inside.
The disc A may have a central metal pivot M (as shown in the upper sash in
Figs. 1 and 2, and in Fig. 4), or may itself serve as a pivot (as shown in the lower
sash in Figs. 1 and 2).
By unscrewing the centre pivots M M (if such be employed) and detaching the
false rebates G from the sashes, the sashes can be easily withdrawn from the discs
when required by a person within the building.
The sash may be secured at any required angle by means of a thumb screw N
fixed at an angle on the pulley stile D, the said thumb screw N engaging with a
metal striking plate or ring P on the disc A. Or if preferred I may employ,
for the lower sash or for single sash windows, the stay R, which may have an extra
horizontal hinge S and vertical hinge or pivot T, thus having four separate motions,
so as to allow the said stay to take the positions shown respectively in Figs. 1 and 2.
The upper sash is preferably provided with a spring catch V, of any suitable
form.
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. In a pivotted window the employment of discs fixed to the sash and revolving
within recesses in the frame, and either with or without a central metal pivot,
substantially as shown and described.
2. In a pivotted window the employment, in combination with the aforesaid discs,
of double rebates of the section shown fixed to the frame, the upper and lower
halves of the said rebates being on opposite sides of the sash, substantially as, and
for the purposes, shown and described.
3. In a pivotted window the combination, with the sash and frame, of the

page_text: discs A, A, double rebates E, F, H, false rebates G, G, pivots M, M, thumb screw N,
striking plate P, and spring catch V, all arranged substantially as, and for the
purposes, shown and described.
