I, HORATIO KELSON BROMHEAD of 245 St. Vincent Street, Glasgow, Scotland,
Architect, do hereby declare the nature of this invention to be as follows:-
This invention is designed to effect the more convenient opening of skylights and
fanlights.
It consists of an endless cord working over a flanged wheel in such a way as to
turn the wheel in either direction.
This wheel is fixed upon a rod which forms a scrow on one side of the wheel.
This screw works in a screwed boss or nut placed on an arm or stay fixed to the
sash.
On the other side of the wheel, is a swivel or cup and ball joint, attached to the rod
on which the wheel is fixed.
The action of the endless cord in rotating the wheel, revolves the screw and thus
moves the screwed boss backwards or forwards thereby opening or closing the sash.

page_text: I, HORATIO KELSON BROMHEAD of 245 St. Vincent Street, in the City of Glasgow,
Scotland, Architect, 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 is designed to supply a simple effective opener for Skylights fan- {
lights and casements which are out of reach.
It can be operated a considerable distance from the sash and will not only open
but also fasten the sash in any required position whether open or closed.
It consists of a long revolving screw and travelling nut, operated by a cord or
chain, and pulley wheel. One end of the screw has a ball or button which works
behind a fixed plate attached to the frame or sill of the window or adjacent thereto.
This button and plate form a kind of universal joint, resembling a modified cup
and ball joint, the ball being flattened so as to occupy less space.
It allows the screw to revolve freely whether in a straight or deflected position.
At a short distance from the universal joint is a small pulley wheel firmly attached
to the screw. Over this pulley an endless cord or chain works, the lower end of
which runs on an adjustable rack-pulley.
When the cord or chain is pulled in either direction, the pulley and screw revolve,
and the nut is drawn nearer to, or driven further from the pulley wheel, and this
action opens or closes the sash. Attached to the nut by means of a pivot, swivel or
hinge, is a plate or arm which is fastened to the sash to be opened.
In the universal joint before mentioned, the plate which confines the ball or button,
can be made in two pieces with forked ends, which meet or overlap each other.
