Improvements in Apparatus for Regulating Fanlights.
I, ROBERT LEGGOTT, of the Firm of W. & R. Leggott, Limited, Silens Works,
in the City of Bradford, Brass Founder and Finisher, do hereby declare the
nature of this invention to be as follows:-
This invention has for its object the construction of a simple and effective
apparatus, by which fanlights and the like may be operated from the floor level,
by arranging the apparatus in such a manner that, when the fanlight is closed
or opened to various degrees the same is automatically locked in the desired
position.
In carrying out my invention, I mount a rod of suitable length in a manner
that it will slide in bearings, and connect the rod by one or more links to a
fanlight or the like hinged in the usual manner, and to the opposite end of the
before mentioned rod is connected a lever, on the operation of which, the rod
is caused to slide in the bearings and actuate the link or links and through them
the fanlight.
The fanlight may be automatically secured by combining with the operating
lever a catch pawl made to engage with a notch when the lever and bar are
moved into position for the fanlight to be closed; and in the rod connecting the
before mentioned lever with the fanlight are formed a series of perforations, and
within one of the bearings supporting the said rod is a spindle with which is com-
bined a compressed spring so arranged as to cause the outer end of the spindle
to be in contact with the rod, and when the rod is moved longitudinally in the
bearings on a perforation in the rod appearing opposite the pointed end of the
before mentioned spindle, the end of the spindle engages therein, thus auto-
matically locking the rod and fanlight which may be further or more permanently
secured on tightening a screw in the said bracket.

I, ROBERT LEGGOTT, of the Firm of W. & R. Leggott Limited, Silens Works,
n the City of Bradford, Brass Founder and Finisher, do hereby declare the
[Price 8d.1

page_text: 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 has for its object, the construction of a simple and effective
apparatus, by which fanlights and the like may be operated from the floor level,
by arranging the apparatus in such a manner that, when the fanlight is closed,
or opened to various degrees of inclination, the said fanlight is automatically
retained or locked in the desired position.
In describing my invention in detail reference is made to the accompanying
sheet of drawings, in which,
Fig. 1, represents the side elevation of my improved apparatus connected to a
fanlight frame, a portion of which is broken off at each end.
Fig. 2, is an elevation of the lever by which the sliding rod is operated, and
the catch lever by which the fanlight frame may be secured when closed.
Fig. 3, is a lever for operating the sliding rod without the catch lever and,
Figs. 4 and 5 are detached details in elevation and section respectively, drawn
to an enlarged scale showing the arrangement by which the sliding rod and
fanlight are automatically secured and held in the position required.
In carrying out my invention, I mount a rod A, of suitable length in a manner
that it will slide in bearings B and B and connect the rod A by a link C to a
bracket D secured to a fanlight frame E hinged in the usual manner.
The bottom end of the rod A, terminates at a convenient distance from the floor
and is coupled by a link F to a lever G mounted to bracket H by a pin J, the
lever G is recessed and fitted with a lever K, at one end of which is a catch K'
arranged so as to engage with a fixed catch bracket K2 when the lever G is moved
to the position shown by Fig. 2, and the fanlight E closed. A spiral spring L
is mounted on a bar and compressed between the lever K and a portion of lever G
in a manner for keeping the lever K in position for the catch end K¹ to engage
with the bracket K³, when the fanlight is closed.
The fanlight frame E may be automatically secured in a closed position by the
catch K engaging with the catch bracket K² as before described, and when the
fanlight frame E is opened to an inclination somewhat as shown by Fig. 1, the
rod A, connected to the lever G and bracket D in the manner as hereinbefore
described has one or more indents M cut therein, so that on the said rod sliding
through a bearing bracket B on an indent M in sliding rod A passing over the
end of pointed spindle N, the pointed end of said spindle engages with the indent
on the liberation of the spiral spring P, compressed between a shoulder on said
spindle and the bottom of recess of bearing bracket B in a manner so as to force
the said spindle outwards and thereby automatically engage with the indent,
thus locking the rod A and therefore the fanlight frame E in the position required;
which may be more definitely secured on tightening screws S at the top of the
bracket bearing B, by which the sliding rod A, is rigidly held in the said bearing
bracket.
The fanlight frame E, may be secured in a closed position and there held by
the spindle N, without the application of the catch lever K and fixed catch
bracket K3, by arranging an indent M, in the sliding rod A, and placing a bearing
bracket B in the position when the fanlight is closed that the spindle N of said
bracket engages with the indent in the sliding rod A, the fanlight frame E, is
thus automatically secured on the closing of same, by the end of spindle N
engaging with an indentation of rod A, cut in the required position.
By forming the end of spindle N, conical and the indentations M, curved
somewhat as shown, on operating the lever G, the side of an indentation on
pressing against the conical end of the spindle N, forces the said spindle within
the bearing bracket B, a distance until the end of spindle is clear of the indent,
and in contact with the straight surface of the sliding rod A, which may then be
further operated by the lever G, for bringing the fanlight frame E into another

page_text: position where it is again automatically retained by the conical end of spindle N,
engaging with another indent M cut in the sliding rod A.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is:
A lever G with or without the lever K, a sliding rod A having indentations M
cut therein, combined with a spindle N arranged and operated substantially in the
manner as shown and described and for the purpose as hereinbefore set forth.
