PROVISIONAL SPECIFICATION.
Improvements in and relating to Sliding Window Sashes.
I, HENRY GEORGE STRATFORD, of 32, Fanshawe Street, Newtown, Southampton,
Joiner, do hereby declare the nature of this invention to be as follows:-
This invention for improvements in and relating to sliding window sashes has
for its object an improved arrangement whereby the window sashes can be secured
in any position either partially open at the bottom or partially open at the top
or in a fully closed position and no ordinary sash fastener is required.
According to this invention within the frame of the window upon suitable pivots
at each side toothed wheels are fitted, two at each side and a chain barrel is formed
upon each of these wheels. In each case the chain is wound round one barrel and
passes through a sheave by which a balance weight is supported and is then
coiled round the barrel on the other wheel. A rack is formed on each of the
sashes at each side with which the toothed wheels gear.
As one of the sashes is moved the corresponding toothed wheels are rotated by
the rack and the chain wound or unwound raising or lowering the balance weight
In order to fasten the sashes in any position a pin is inserted so as to engage
between the teeth of the wheels, and it will be seen that their rotation is thus pre-
vented and consequently the sashes cannot be moved. The window can thus be
secured in either a partially open position or fully closed and until the pins are
removed cannot be moved.
The frames of the window are fitted with panels which when removed allow of
access to the mechanism above described.
Doted this 23rd dox of April 1898.

Improvements in and relating to shuin Dashes.
I, HENRY GEORGE STRATFORD, of 32, Fanshawe Street, Newtown, Southampton,
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 for improvements in window fastening and locking apparatus
has for its object an improved arrangement whereby the window sashes can be
secured in any position either partially open at the bottom or in a fully closed
position and no ordinary sash fastener is required.

page_text: In order to more clearly describe this invention reference is had to the accom-
panying sheet of illustrative drawings on which.
Fig. 1 is an elevation of a window fastening and locking apparatus constructed
according to this invention, and
Fig. 2 is a sectional side elevation of the same. In the drawings only one set
of apparatus is illustrated and it will be understood that the arrangement at the
other side is similar and the two sets work together.
Within the window frame, which is hollow at each side, upon pivots a, toothed
wheels b bare fitted, two at each side. The toothed wheels are provided with
chain barrels cel attached to or formed in one with them. A chain d is wound
round the barrel c and passes through a sheave e by which a balance weight f
is supported and is then coiled round the barrel c¹. Each of the window sashes gg¹
is provided with a rack h h¹ with which the teeth of the wheels bb engage.
As one of the sashes g g is moved the corresponding toothed wheels bor b
are rotated by means of the racks h or h¹ so that the chains d are wound or unwound,
raising or lowering the balance weight. The sashes will therefore remain in any
position in which they are placed.
In order to fasten the sashes g g¹ in any position a pin i is inserted so as to
engage between the teeth of the wheels bb, and it will be seen that their rotation
is thus prevented and consequently the sashes cannot be moved. The window
can thus he secured in either a partially open position or fully closed and until
the pins are removed cannot be moved.
The window frame is fitted at each side with panels j which when removed
allow of access to the mechanism. The pins are passed through openings j
formed in these panels and when not required for securing the window are drawn
forward sufficiently out of engagement with the wheels b b¹ or may be moved
altogether until required.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
I claim is —
(1) An improved window fastening and locking apparatus comprising toothed
wheels mounted in the window frame at each side and engaging by means of
racks with the sashes, barrels attached to or formed on said toothed wheels and
round which chains pass, the said chains serving to support a balance weight and
pins which can be inserted to engage between the teeth of the toothed wheels to
prevent their rotation and thus secure the sashes in either a partially open position
or fully closed substantially as described.
(2) In a window fastening and locking apparatus, toothed wheels b b¹ mounted
on pivots a, barrels el attached to or formed in one with said toothed wheels b b₁,
chain d, sheave e, balance weight f, racks h h on the sashes g gl and pins i all
arranged and operating substantially as described with reference to the drawings.
