PROVISIONAL SPECIFICATION.
A New or Improved System of Hanging Sliding Windows to be
Opened from the Inside for Cleaning and other Purposes.
WILLIAM THOMAS HOOKER, Builder, of St. Martins Vale, Northend, Erith, in
the County of Kent, do hereby declare the nature of this invention to be as
follows:-
The window is hung by the means of hinges.
The hinge consists of a circular pin and cup to receive same, the centre from
which they work being for bottom sash about three eights from angle of inside
beed.
For the top sash, in centre of pulley stile covered by bottom sash when down.
The part or wing attached to centre pins or cups are 'brought round in bottom sash
to lining on frame, the other wing of hinge, or cup part, is brought to stile of
sash. The above centre pins, cups & arms are dovetailed into slotted and dove-
tailed plates to be let into stiles (left hand) of bottom and top sash on face of
same, and are removable. The pins are attached to frame & cups to the sashes,
and are placed in position so that the sashes can be drawn down on top of pins &
opened without removing any inside beed or parting slip on left hand side of sash
frame.
The hinge I may describe as pin and cup with arms dovetailed into slotted
plates. The plates remain fixed and arms renovable. The said arms will answer
for all the house built with same frames.
grip
I propose to keep up weights to top of frame, by a tapered and notched più to
the line and so fixed that the heavier the weight. the safer the grip on line.
propose to hang beed with hinges on right hand side and use a cup for knob of
line on right hand side of sash so that the line can be easily disengaged.
On left hand side the lines remain the same as when hung in the ordinary way,

COMPLETE SPECIFICATION.
A New or Improved System of Hanging Sliding Windows to be
Opened from the Inside for Cleaning and other Purposes.
WILLIAM THOMAS HOOKER Saint Martins Vale North End Erith, Builder
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 :-
My invention has for its object the hanging and opening of windows hung in the
usual way with cords, pullies and weights for the cleaning of and other purposes.
With this object
construct detachable hinges the wings of which are attached
to plates on sash frames, and sashes, and in order to do this I insert plates slotted
and dovetailed to receive the wings of hinges. The lower wings of hinges, being
connected to the plate on the frame and the upper wing being connected in a
similar manner to the style of sash.
To effect the connection the bottom sashes are raised a few inches above the sill
the object of raising the sash being to clear the sill and also to connect the upper
and lower wings of hinges of bottom sashes.
The bottom sash being then in position for opening after opening the sash bead
which may be hinged or otherwise.

page_text: I propose by means of hinged clips fixed above the pullies of gripping the cords
thereby suspending the weights. The lines or cords being now disengaged, the
bottom sash can be swung on its hinges.
Plates as before described are inserted into pulley styles to receive wings of
hinges for top sashes and brought to the same level as bottom sashes part of
parting bead being removed and the weights suspended as before described. Sash
can be swung.
I also insert hooked plates in the sides of the sashes so as to disengage the sash
cords quickly when gripped by the hinged clips.

claim is
The application of hinges in connection with frames and sashes, also hinged clips
for sliding sashes of windows, for the purpose of cleaning or otherwise.
