PROVISIONAL SPECIFICATION.
Improvements in or applicable to Windows, Fanlights, and
Ventilators for Opening, Closing, Adjusting, and Fastening
the same.
EDWARD DREW 168, Hulton Street, Trafford Road Salford, in the County of
Lancaster, Foreman Joiner do hereby declare the nature of this invention to be as
follows: :-
For opening, closing, adjusting and securely fastening windows, fanlights and
ventilators, at any height, by a person standing on the floor. An endless cord
passing over a grooved pulley and worked by hand causes the pulley to travel on
screw quadrant carrying the sash along with it to the required distance and
remaining securely fastened in any position. On window being closed the screw
by having a joint, and only a thread on the top slides easily along and drops down
quite clear and out of way of window blind irrespective of the length of screw, by
the removal of two split pins the pulley can instantly be lifted clear of window for
cleaning or any other purpose.

I EDWARD DREW of 168 Hulton Street, Trafford Road Salford in the County
of Lancaster Foreman 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 or applicable to windows, fanlights,
and ventilators, for opening, closing adjusting, and fastening the same, such
windows, fanlights, and ventilators being fitted to swivel or swing in their frames.
The invention is illustrated by the accompanying drawings in which
Fig. 1. is a side view of the improved devices attached to a frame shewing the
same closed.
Figs. 2 & 3. are respectively a sectional view of the screwed quadrant, and a
front view of the improved devices detached.
The improved devices comprise a long screwed quadrant A which is fixed to the
framing B of the window in close proximity to the edge of the moveable sash C
and a grooved pulley D fitted to turn on the screwed quadrant as a nut.
Over the pulley Ď is passed a cord by means of which the grooved pulley D is
turned on the quadrant A.
The pulley D in turning travels along a screwed quadrant A drawing with it the
edge of the window frame to which it is secured, and thus opening the window to
any extent desired.
The screwed quadrant A is made in two parts and jointed at E near to where it
fastens on the window frame B so that when the window is closed the quadrant
drops down quite clear and out of the way of window blinds &c.

page_text: There are also two split pins at F which when withdrawn allow of the pulley.
and quadrant being lifted clear of window for cleaning or any other purpose.
There is also a small pulley at G over which the screwed quadrant travels, and
two small pulleys fixed close together at H between which the cord travels and
increases the grip upon the pulley D.
There is also a knob I on end of the screwed quadrant that can be taken off for
the purpose of passing pulley D over.
There is a hole at J through which the cord passes.
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. The arrangement of the screwed quadrant A in combination with the grooved
pulley D, the one being fixed to the window frame and the other to the moveable
sash, and the pulley being operated by an endless cord.
2. The screwed quadrant jointed at E to allow it to drop down quite clear of
window blinds on window being closed.
3. The pulley at G to allow the quadrant to run easily along when the window
is closed or opened.
4. The two small pulleys at H to increase the grip of the cord upon the
pulley D.
5. The arrangement of the two split pins at F allowing the pulley and quadrant
to be lifted out clear of window for cleaning or any other purpose.
6. The knob on end of arm capable of being screwed off for the purpose of
passing pulley D on to the quadrant.
Dated this Thirtieth day of November 1893.
