PROVISIONAL SPECIFICATION.
Improvements in or relating to Window Sashes or Frames.
I, WILLIAM JACKSON, of 3, Cambrian Street, Holbeck, Leeds, in the County of
York, Joiner, do hereby declare the nature of this invention to be as follows:
This invention relates to improvements in window sashes. The object of this
invention is to provide simple and ready means for enabling a window to be turned
on a pivot for facilitating the cleaning thereof, without interfering with the con-
struction of the stile and linings and at the same time to provide means for securely
locking the sash in position for sliding up and down in its race.
According to this invention the upright or vertical sliding portions of the sash
are made, say, about half the thickness of the horizontal cross bars. To the vertical
portion of each sash is pivoted as hereafter described at or about its centre, a frame
(of or about the same thickness as the before mentioned vertical portions) in which
the window pane, or pames are fixed.
The pivot consists of a bearing or casting is fixed to the first named vertical
sliding portions of the sash, that is to say one bearing or casting on each side
thereof. Into each bearing or casting is screwed a pivot pin or screw, which passes
through the upright portion of the said frame in which the pane or panes of glass
is or are inserted. For the right hand side bearing or casting the pivot pin or
screw is preferably provided with a left hand thread and the left hand bearing or
casting with a pivot pin or screw with a right hand thread. By this means when
the outside of the window is turned on the pivot inwards for cleaning purposes
there will be greater freedom in turning. And when the frame is returned to its
normal position the pivot pins or screws aid in securely locking it in position.
On each side of the sash, and at a suitable distance from its lower edge is pro-
vided a spring hook, or sneck catch say of the mortice type, or its equivalent ier
securely holding and locking the frames firmly in position (whenever the frames
is closed) with the vertical sliding portions.
The spring hook or sneck catch is provided with a projection, which runs parallel
with the window pane or panes for facilitating the opening of the said hook or
sneck whenever the frame is required to be turned on its pivots.
The sill and top rails of the sashes may be respectively suitably grooved and
rebated for additional security.
When the frame is closed in position for sliding purposes, it has all the appear-
ance of an ordinary sliding window sash, and the upper and lower sashes of the
window may be secured together by fastenings of the usual and ordinary type.

I, WILLIAM JACKSON, of 3, Cambrian Street, Holbeck, Leeds, in the County of
York, Joiner, 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 window sashes. The object of this
invention is to provide simple and ready means for enabling a window to be turned
on a pivot for facilitating the cleaning thereof, without interfering with the con-
struction of the stile and linings and at the same time to provide means for securely
locking the sash in position for sliding up and down in its race, as well as pro-
viding a ready and simple means for obtaining access to the sash cords and weights
when it is required to repair or attend to the same.
In the drawings hereunto annexed:-
:-

Fig. 6 part elevations and top and bottom plans of the cord stile.
Fig. 7 part elevations and top and bottom plans of part of swinging stile.
Figs. 8 to 12 are respectively a sectional elevation, end elevations and a plan of
the sash catch or fastener and its retaining plate.
Figs. 13 and 14 a sectional elevation and an elevation of the pivot plate and its
nut.
Like parts in all the views are marked with the same letters of reference.
A A are the upper and lower sashes which are glazed in the ordinary manner,
it the sides thereof are constructed and made to slide and turn in the races of
the window frame as hereafter described.
The window frame is formed in a similar manner and presents, when the sashes
are closed in position for sliding up and down in the races 661, the appearance of
a window frame of ordinary construction. It consists of a window head B, shaped
as shown at Fig. 5, and has a recessed portion on its inner side, and a projection 12
to form a stop against which the upper portion of the sash head a of sash A abuts
when the latter is in a closed position. B¹ is the sill of the window frame and it
is provided with a projection 3 (which enters a recess in the sash rail a¹ of sash A¹)
on the raised portion between the staff bead B2 fixed to or on the inside lining B³,
and parting bead B. The window head B and sill B₁ are connected together by
the vertical portions hereafter termed the pulley stiles B5, having the races bb
provided for the sashes A A' to slide therein-respectively between the staff head 132
and parting bead B, and between the parting bead 13* and projecting or overlap-
ping portion of the outside lining 16 as shown at Fig. 2. B7 B8 are the sash
weights which work in the recesses or pockets of the window frames formed by the
division board B which also separates them. The sash weights are connected to
the sashes by cords B10 working over pulleys B let into the pulley stiles B5 in
the usual manner and are of ordinary construction.

page_text: Instead of forming the upright or vertical portions of the sashes A A',-which
pass into and slide in the races bb,-in the usual manner, I form the vertical sides
of each of the sashes in two portions termed respectively the cord stiles or runners C
and glass stiles a³. The cord stiles or runners Care made, say, about one half the
thickness of the horizontal cross bars of the sashes, and they are provided with
projections c, shown at Fig. 6, which fit into the recesses a¹ of the glass stiles a³
shown at Fig. 7. Each cord stile or runner is provided at the back with a
recess c¹ into which the cord 1310 passes, and its main portion is made rather thicker
than the distance that the outside lining 136 parting bead 134 and staff bead 132 on
inside lining 13 project from the faces of the pulley stiles 13. The cord stiles or
runners C are made to pass respectively into the races, that is to say, there is
a cord stile or runner Con each side of the sashes A and A¹.
and
The sashes A and A¹, which are formed of the two uprights or glass stiles
the top and bottom horizontal portions termed respectively the sash head a and
sash rail, and they are glazed at D in the ordinary manner.
The cord stiles or runners C and glass stiles a are pivoted together at or about
their centres as hereafter described respectively in the spaces between the pro-
jections c and recesses a, and the projecting portions on both the cord stiles or
runners C and glass stiles a serve the double purpose of preventing the sashes A A¹
swinging too far, and of making the sashes weather proof.
forms a
The pivot, shown at Figs. 13 and 14, consists, of a bearing or casting E which
nut and is fixed into the cord stile or runner C so as to
be level with its face. A bearing E is provided for each cord stile or
runner so that there is a bearing on each vertical side of the sashes A and A¹.
Into each bearing or casting E is screwed a pivot pin F in the form of
a screw without a head which passes through the upright portion of the
glass stile in which the pane or panes of glass D is or are inserted. For the
right hand side bearing or casting E the pivot pin F is preferably provided with
a left hand thread, and the left hand bearing or casting E, with a pivot pin F,
with a right hand thread. By this means when sash is turned on the pivot pins F
inwards as shown in dotted lines at Fig. 1, for the outside of the window to, say,
be cleaned, there will be greater freedom in turning. And when the sash is
returned to its normal position the pivot pins aid in securely locking it in position.
In order to turn either sash on its pivots Fit is necessary to respectively first
lower the sash A in its race b, or to raise the sash A' in its race 61 before commenc-
ing the turning operation so as to ensure of the sash head of sash A clearing
the projection, and the sash rail a¹ of sash A' clearing the projection b³.
On each side of the sash, and at a suitable distance from its lower edge is pro-
vided a spring hook, or sneck catch G say of the mortice type, and of a similar,
construction to that shown at Figs. 8 to 10 consisting of a hook G pivotted in a
box like casing which is let into the glass stile --so as to be capable of being
acted upon by a spring g'. The spring hook G is made to engage with a catch
plate G (see Figs. 11 and 12) fixed to the cord stile or runner C.
Or other equivalent means may be employed for securely holding and locking
the frame or sash proper firmly in position (whenever it is closed) with the vertical
sliding portions herein termed the cord stile or runner C.
The spring hook or sneck catch G is provided with a projection or heel g³, which
runs parallel with the window pane or panes D for facilitating the opening of the
said hook or sneck whenever the sash is required to be turned on its pivots F.
The bottom and top rails of the sashes may be respectively suitably grooved and
rebated for additional security.
When the sashes are closed and locked with their respective cord stiles or
runners C in position for sliding purposes, it has all the appearance of an ordinary
sliding window sash, and the upper and lower sashes of the window may be secured
together by fastenings of the usual and ordinary type.
By the herein described means it will be readily seen that when the spring
hooks G are released from their catches G¹ the upper or lower sash, after it has

page_text: been lowered or raised so as to be clear of the projections on the window frame, is
then free to be turned on its pivot pins F. Further free access may be had to the
sash cords B10 when they require repairing or for other purposes. To do this all
that is required is first to withdraw the pivot pins F from their nuts or bearings E
and then to remove the sash from between its cord stiles or runners C, leaving the
cords attached to the latter, when the cord stiles or runners are free to be withdrawn
from their respective races 6 or 61 without further disturbing or damaging the
window frame.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The improvements in window sashes and frames substantially as herein
described, consisting essentially of cord stiles or runners such as C arranged to
slide in races such as bb' of a window frame provided with projections such as b² 63
respectively on the window head and sill, and sashes, such as A A' arranged to be
pivotted to said cord stile or runners such as C by pivot pins such as F, working
in nuts, such as E, and to be secured to said cord stiles or runners by a spring
catch such as G and catch plate such as G', all arranged and combined sub-
stantially as.and for the purposes herein described and as illustrated in the accom-
panying drawings.
2. The combination with a window sash, such as A or A¹, of cord stiles or
runners, such as C, adapted to slide in the races such as 661 of a window frame,
and to be centrally pivoted to the said sash, and afterwards secured to the said
cord stiles for sliding up and down in the said frame, as and for the purposes
herein before described.
