Improvements in or relating to Sliding and Swinging Window
Sashes.
I, WILLIAM NICHOLSON, of the Saw Mills, Shieldfield Lane, Newcastle-on-
Tyne, in the County of Northumberland, Foreman Joiner, do hereby declare the
nature of this invention to be as follows:-
This invention refers to sliding window sashes in which sashes may be swung
upon a horizontal axis so that the outside of the glass may be as easily cleaned as the
inside. While the sash is swung it is kept from sliding by means of a bolt engaging
in the pulley stile. This bolt is so arranged and placed that the sash cannot be
swung without first locking the sliding state of the sash to the pulley stile of the
frame. This bolt and its fittings are preferably applied on and in relation to the
top of the meeting rail of the bottom sash, and at one or both ends. On the top
sash it may be fixed to or in relation to the head rail or the meeting rail whichever
may be most convenient. Corresponding holes are made in the pulley stiles to suit
the position or positions of the sashes when required to be swung. The pivot by
which the sash is connected to the sliding stile consists of two plates connected
together by a centre bolt and fixed to the swinging and sliding stiles respectively.
The contact surfaces of these plates are perfectly flat and kept close together by
means of a spring between the bolt head and one of the plates thus tending to
make them draught proof and also self holding, that is, that, the window, when
slung, will stay in the position in which it is put.
The plates may be the full length of the surface and provided or not with weather
beading so that when the window is closed the joint is both weather and draught
proof. The pivot is not necessarily in the middle of the swinging stile. Stop
pieces may be provided on the pulley stile so that the top sash may only slide down
a certain distance sufficient for ventilation or for swinging.

Sashes.
I, WILLIAM NICHOLSON, of Saw Mills Shieldfield Lane Newcastle in the
County of Northumberland, Joiner do hereby declare the nature of this invention
077

page_text: and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:-
This invention refers to sliding window sashes, in which the sashes may be swung
upon a horizontal axis so that the outside of the glass may be as easily cleaned as
the inside. While the sash is swung it is kept from sliding by means of a bolt
engaging in the pulley stile. This bolt is so arranged & placed that the sash
cannot be swung without first locking the sliding stile of the sash to the pulley stile
of the frame. This bolt and its fittings are preferably applied on or in relation to
the top of the meeting rail of the bottom sash, and at one or both ends. On the
top sash, it may be fixed to or in relation to the top rail or the meeting rail which
ever may be most convenient: corresponding holes are made in the pulley stiles to
suit the position or positions of the sashes when required to be swung. The pivot
by which the sash is connected to the sliding stile consists of two plates connected
together by a centre bolt and fixed to the swinging and sliding stiles respectively.
The contact surfaces of these plates are perfectly flat and kept close together by
means of a spring between the bolt head or nut and one of the plates. The bolt
head is preferably of a conical or cup like form fitting into one of the plates,
preferably the plate on the swinging stile, while the other end of the bolt is fixed
or connected to the other plate. In cases where it is required to take out the
swinging sash without interfering with the staff or parting beads or, the pivot
plate fixed to the swinging stile is provided with a hinged piece pivoted at one end
to the plate, and the other end connected to the plate by a bolt which may be
provided with a spring. This bolt. by the action of the hinged piece on the cupped
or conical head of the connecting bolt will regulate the pressure on the contact
surfaces of the pivot plates. The pivot will be draught proof and self holding, that
as the window when swung will stay in the position in which it is put. The plates
may be the full length of the surface provided with weather beading, so that when
the window is closed the joint is both weather and draught proof. The pivot is
not necessarily in the middle of the swinging stile. Stop pieces may be provided
if necessary on the pulley stile so that the sashes may only slide a certain distance
sufficient for ventilation or for swinging.
In the annexed drawings
Fig. 1 is an elevation of the locking bolt suitable for top rail or meeting rail.
Fig. 2 is a plan of the same.
Figs. 3 and 4 are side and front elevations of the bolt arrangements suitable for
the meeting rail.
Figs. 5, 6, 7, 8 are elevations of the pivots.
Fig. 9 shows also an elevation of a pivot which is used for large windows where
it is considered necessary to increase the holding power of the pivot.
The dotted positions in Figs. 1 and 4 show the bolt in place & window free to
swing.
A represents the sliding stile. B the swinging stile, C is the bolt and Ca
projection on bolt C sliding in slot F. D is a plate or casting fixed to sliding
stile A and through which bolt C works. E is a guide slot for bolt C. F is a plate
or casting fixed to the rail, are surfaces of projections on plates D and F which
are in contact when window is shut, and, which are inclined obliquely to the front
of the meeting rail to draw the swinging & sliding stiles close together. G is a spring
on side of the bolt C. H is the pivot plate on the sliding stile. J is the pivot
plate on the swinging stile. K is a hinged piece hinged at L and held down by the
bolt M which may be provided with a spring. P is the bolt for connecting the
pivot plates H. J. together. Q is the cupped head of the bolt I fitting into
suitable recesses in plates J J and K. R is a tightening handle working against
an inclined surface S on plate K. V is a set screw for the bolt M. T is a flat
spring that may be used with the bolt P.
It will be obvious that by fixing the sliding stiles or adopting equivalent fixed
side supports, the invention is applicable to fixed frames.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
(1.) A window sash having pivoted to it two sliding stiles in combination wit
a bolt or bolts adapted to be moved to secure said stiles against sliding movement
in the window frame and to permit the sash to be swung on its pivots or conversely
adapted to be moved to another position in which the sliding stiles are free to move
but the sash is secured from swinging on its pivots.
(2.) A window sash having pivoted to it two sliding stiles in combination with
a bolt or bolts constructed and fitted substantially as herein described and intended
for obtaining either sliding or obtaining swinging movement but not both at the
same time.
