Improvements in Opening and Closing Fan Lights and the like.
I, JOSEPH KAYE, of Bank House, Kirkstall, Leeds, in the County of York, Lock
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in the method of, and apparatus
for opening and closing Fan Lights, and has for its object the opening of such with
ease, and facility, without the use of strings, ropes, chains, or gearing such as worms,
and quadrants hitherto in use for such purpose.
I accomplish my object by securing to the side of the fan light frame, a rod
secured top and bottom, but at an angle, that is to say, the rod is secured nearer to
the frame at the binges of the fan light, and further away at the top of the same.
To one side of the frame work of the window, I secure a rod, surrounding this
rod, I have a tube moveable upon the same in a vertical direction; to the tube I
secure a bracket, to which is centred at right angles to the rod, a pin or small shaft,
free to move within a boss on the bracket, on to one end of which I mount a tube,
which tube embraces, and is free to slide, upon the inclined rod, secured as above
described, to the fan light.
When the fan light is closed, the small tube embracing the rod on the fan light is
at the top of such rod, and when it is desired to open the fan light, the tube
embracing the rod on the frame work of the window, is pulled down the rod, and
with it, the attached bracket and the centred tube travels down the inclined rod on
the fan light, and thus opens the fan light.
When it is desired to close the same, the tube on the rod, secured to the window
frame is pushed up.
The fan light can be fixed at any intermediary point between close shut, and
wide open, by securing the tube in the required position on the rod secured to the
frame work of the window.
Dated this 11th day of September 1888.

Improvements in Opening and Closing Fanlights and the like.
I, JOSEPH KAYE, of Bank House, Kirkstall, Leeds, in the County of York, Lock
Manufacturer, 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 certain improvements in the method of and apparatus for
opening and closing fanlights and the like, and has for its object, the opening of such
with ease and facility without the use of cords, ropes, chains, or gearing such as
worms and quadrants hitherto in use for such purpose: and consists in securing to
the fan light frame, a rod at an angle therewith, and embracing this rod is a collar
attached by an arm to a tube moyable in a vertical direction on two tubes attached to
the window or door casement: and enclosed within the first named tube and one of
the latter is a spiral spring and stay rod for preventing the fanlight if carelessly
opened falling too far and damaging the same, and also for assisting to close the fan
light when the retaining screw is liberated.
In the accompanying drawings Fig. 1. represents a front view of a portion of a
door frame and fan light with my improved opener attached thereto.
Fig. 2. is a side view of the same.
Fig. 3. a section through lines a. b. and
Fig. 4. is a view drawn to a reduced scale showing the fan light or window open.

page_text: The fan light A. is shown hinged at B. to the door casement or frame C. and
secured to the fanlight A. is a bar or rod D. at an angle thereto, the said rod being
nearest to the fanlight at the bottom end next the hinges B.
Upon this rod D. is a collar or sleeve E. free to slide thereon, and is mounted on
the arm F. attached to the tube G. which is free to slide on the tubes H. and H' both
of which are secured to the door or window casement C. the tube G. being held in
any desired position by the screw K.
Within the tubes G. and H¹ on stay or guide rod L. is a spiral spring S. compressed
between the bottom of tube HI' and a support M. secured in the interior of tube G.
which on the attendant liberating the tube G. by releasing the screw K. prevents the
fanlight turning or falling quickly on its hinges and damaging the former; and also
serves the purpose of assisting to raise the fanlight or window on closing the same.
It will be observed that by this arrangement the fanlight can be retained at any
intermediary point between wide open and closed, and when closed, the sliding
collar or sleeve E. is near the top of the inclined or angular bar D. at the opposite
side of the fanlight or window frame to that of the hinges B. by which, support is
given to the fan light or window when the same is closed.
A fanlight or window hinged at the top instead of the bottom as shown at B. may
be opened and closed by my apparatus, in which case the angle of the bar or rod D.
in relation to the fanlight or window is reversed, the greatest distance between the
bar or rod D. and fanlight being at the bottom instead of at the top as shown on
drawings so that on raising the tube G. on H¹ the window is opened outwards.
By attaching the top portion of the sliding tube G. to the upper half of a sliding
fanlight or window somewhat as shown by Fig. 5. and the bottom tube H to the
bottom portion of the window or to the casement of same, the fanlight or window
may be opened and retained in any position, the tube G. sliding on the tube H¹ and
secured thereon where required by tightening the screw K. so that the window
cannot he further opened or closed until the screw K. is released.
Fanlights or hinged windows may also be operated by the sliding tube G. in
conjunction with a lever L' arranged somewhat as shown by Fig. 6. in which case
the lever I having two arms is supported by a fulcrum pin M. passing through the
centre and attached to a bracket or in any convenient manner to suit the surroundings;
one arm of the said lever being connected to the window by link N. and the other
arm to the sliding tube G. so that on the latter being moved on the tubes H. and H¹
in the manner as before described, the lever is operated on its fulcrum pin M. and
the fanlight or window opened or closed according to the direction in which the
tube G. is operated.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
1. The hereinbefore described apparatus for opening fanlights or windows in which
are combined a rod D. sleeve E. tubes G. H. and locking screw K. and spiral
spring S. all arranged substantially as described.
2. The combination of rod D. sleeve E. tubes G. H. and H with the locking
screw K. or its equivalent and a fanlight or window substantially in the manner and
for the purpose described.
3. The tubes G. and H¹ and screw K. combined with a lever L' and fanlight or
window substantially in the manner and for the purpose hereinbefore set forth.
4. The tubes G. and H. and screw K. in conjunction or otherwise with the
spring S. combined with a sliding fanlight or window A. arranged substantially in
the manner shown and described.
