Improvements in Apparatus for Regulating the Opening and
Closing of Fanlights, Casements, and other Windows.
I HENRY WHITELEY, of Middle Goat House, Rishworth near Halifax in the county
of York, Joiner do hereby declare the nature of this Invention to be as follows
My opener consists of a pivotted slotted bracket, attached to the fixed frame of the
casement or window, in the slot of this bracket is a runner attached to a bar or arm,
at the other end of the bar or arm is formed a toothed quadrant which is operated by
a worm, carried in suitable brackets, and attached to the casement or window to be
opened, or shut; the worm is operated by a pulley and cord or chain, the action is as
follows; when the window is closed, the bar lays close to the casement clear of the
window to be opened, on turning the worm one way, it opens the casement drawing
out the bar along the slot about five revolutions, opening the casement, on turning the
worm the opposite way, the bar is pushed back along the slot to its original position,
and at whatever position the casement is left, whether fully or partially opened or
closed, it is perfectly secure, it will open any kind of casement in any required
position.
Dated this Twenty ninth day of September 1886.

I HENRY WHITELEY, of Middle Goat House, Rishworth near Halifax in the County
of York 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 :-
My opener consists of a pivotted slotted bracket attached to the fixed frame of the
casement or window in the slot of this bracket is a runner attached to a har or arm,.
at the other end of the bar or arm is formed a toothed quadrant which is operated by
a worm, carried in suitable brackets and attached to the casement or window to be
opened or shut; the worm is operated by a pulley and cord or chain, the action is as
follow: When the window is closed the bar lays close to casement, clear of the window
to be opened on turning the worm one way it opens the casement by forcing out the
end of the bar upon which the runner is carried, the said runner passing along in the
slot of the pivotted bracket.
By reversing the revolution of the worm the end of the bar carrying the runner is
forced inwards and the window is thereby closed.
In whatever position the window is placed whether fully or partially open or
entirely closed it will remain in that position until the worm is caused to revolve;
and the same mechanism will open any kind of hinged or pivotted window or fanlight
in any position.
In order to enable my invention to be fully understood I will proceed to describe
the same with reference to the accompanying drawings in which
Fig. 1 represents a plan partly in section of a closed fanlight to which my improved
opener is attached and
Figure 2 represents a front elevation of the upper portion of the same.
Figure 3 represents a transverse sectional elevation of an opened fanlight to which
my opener is attached and
Figure 4 represents a plan of the same, the top bar of the casement being removed.
Similar letters refer to similar parts in all the drawings.
The fanlight or window is represented at A, to which is jointed or hinged the slotted
bracket B, in which travels the runner C, pivotted upon one end of the hinged bar D,
the hinge or joint of this bar being at E and the quadrant F. The worm represented
at G actuates the quadrant and is operated by means of the cord or chain and pulley H.
The worm and pulley are carried by the bracket J fixed to the top bar of the casement.
The side bars or frames of the casement are represented at K, and guards or guides
to prevent the chain or cord running off the pulley at L.
The bar D is hinged in order to allow it to follow the angle formed by the opening
of the fanlight.

page_text: Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is.
1. In mechanism for opening and closing fanlights or other windows the quadrant F
actuated by the worm G, the hinged arm B and the runner C operating in the slot of
the hinged or jointed bracket B. all substantially as and for the purpose described and
represented.
2. In mechanism for opening closing and securing fanlights or other adjustable
windows the combination of the pulley H operated by means of a cord or chain and
actuating the worm G the toothed quadrant F engaging with the worm G, the hinged
bar D carrying the grooved runner C. and the jointed and slotted bracket B acting as
a double guide rail to control the operation of the runner C. all substantially as and
for the purposes described, and represented in the accompanying drawings.
