I, JOHN PULLAR, of 9 Meadow Entry, Dundee, in the County of Forfar, Window-
blind maker and bell hanger, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to simplify the construction of fanlight actuating gear,
and to securely lock the fanlight when closed.
I effect my objects in the following manner :-
To the frame of window is fixed a moveable joint to which a long rod of T section
is jointed, the other end of said rod being free.
To the moveable fanlight sash is attached a flat plate having an opening in it,
through which the said rod slides.
Underneath this opening is a fulcrum pin upon which moves a latch or lever which
is so made as to be capable of securing said rod in any desired position.
Said latch is bent at such an angle that when one end is lifted or lowered, the
end which engages with the rod is moved laterally, thus moving it backwards and
forwards.
I
The under side of the rod has a series of square notches cut out in it which are of
sufficient size to permit end of latch to pass through; the point of said latch always
pressing upon the side of rod, unless when it is lifted.
The metal between each notch is tapered in such a manner that the end of latch
gradually falls in, to a slight extent, thus making certain that latch will not pass more
than one notch at one time, unless the operator so desires.
The other end of latch has a hole in it; through which a pin fastened to the end of
a long rod is passed if it is desired to lift latch and open or close fanlight.

page_text: Said rod may be used to do so either by pushing or pulling or by turning same.
Instead of using a rod to lift latch, I may use a cord which may be passed over a
guide pulley if desired. The fanlight in that case will be opened or closed in the
ordinary fashion with another and separate cord.
Instead of making the rod of a T section 1 may make it of a tubular section, in
which case the point of latch will slide in slots cut out of the side, the point being
lifted past each complete part of tube.

page_text: I, JOHN PULLAR, of 9 Meadow Entry, Dundee, in the County of Forfar, Window-
blind maker, and bell hanger, 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 :-
The object of my invention is to simplify the construction of fanlight actuating gear,
and to securely lock the fanlight, when closed.
I effect my objects in the following manner :-
To the frame of window is fixed a moveable joint, to which a long rod of T section

is so made as to be capable of securing said rod in any desired position.
Said latch is bent at such an angle that when one end is lifted or lowered, the end
which engages with the rod is moved laterally, thus moving it backwards and

DESCRIPTION OF DRAWINGS.
In these drawings the same reference letters and numerals are used to mark the
same or like parts, wherever they are repeated.
Fig. 1 represents a side elevation showing the fanlight partially open. Figs. 2.
and 3. represent a plan and a front elevation respectively, of the hinge, fastened to
the window sash, to which the curved bar is attached. Figs. 4. and 5. represent a
front elevation and a plan respectively, of the locking apparatus, and Fig. 6. represents
a general view of the fanlight with its actuating gear.

page_text: To the frame of the window 1. is fixed a bracket 2. to which the curved bar 3. is
jointed.
To the moveable fanlight sash 4. is attached a bracket 5. through which the curved
bar 3. slides. Underneath this opening is a fulcrum pin 6. about which a latch 7.
may move when the part A. of the cord 8. is pulled. Said latch may move from the
position shown by the full to that shown by the dotted lines. When in the position
shown by the full lines, the point of the latch is in one of the notches cut out of the
curved bar and when in the position shown by the dotted lines its point is clear of
same and said curved bar may slide through the bracket 5.
Upon the end of the latch is a ball or weight for the purpose of keeping its point
against the side of the curved bar, so that it may more readily pass into a notch.
The metal between each notch is made tapered as shown at 10. so that the point of
the latch gradually falls in, thus making certain that it will not pass more than one
notch at one time, unless the operator pulls the cord at A.
When it is desired to close the fanlight the side of the cord at A. is pulled thus
lifting the point of the latch out of a notch, the side B. of the cord 8. is then pulled
and the fanlight is closed. One end of the cord 8. is fastened to the bracket 5. at 11.
it then passes up round the pulley 12. over the pulley 13. and hanging loose then
passes over the pulley 14. down through the bracket 5. and is then fastened to the
latch 7. at the point 15.
I may use two separate cords for effecting the beforementioned operations, although
I preferably use it as described.
16. is a stop to keep the latch 7. with its weight from falling too far. 17. is a
rubber buffer against which the bracket 5. may strike when the fanlight is allowed to
fall open to its full extent.
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 use of the jointed curved bar having notches cut in it as hereinbefore
described.
(2) The use of the latch as described.
(3) The use of the jointed curved bar in combination with the latch as described.
The use of the apparatus for opening, closing, and locking fanlights as
hereinbefore described.
