PROVISIONAL SPECIFICATION.
An Improved Apparatus for the Adjustment of Fanlights and
the like.
I, GEORGE DEACON, of Lower Thrift Street, Northampton, in the County
of Northampton, Horticultural Builder, do hereby declare the nature of this
invention to be as follows:-
My invention relates to an improved apparatus for the adjustment of fanlights
and the like, which consists of a long straight bar pivoted to a plate, the said long
straight bar is cut with a male thread of any suitable length on the outside, this
said male screw operates in a female screw cut in a ball enclosed and working
loosely inside a cog wheel, the said cog wheel is in two halves and screwed or
rivetted together. The cog wheel is mounted in bearings on a suitable frame, and
the said wheel is operated by pins fixed on the face of a pulley wheel mounted on
a spindle which revolves in parts of the frame. The pulley wheel is driven by an
endless cord. The ball is provided with one or more projecting pins or rockers to
work in a seating cut in each half of the cog wheel hereinbefore described.
Dated this 15th day of May 1896.

COMPLETE SPECIFICATION.
An Improved Apparatus for the Adjustment of Fanlights and
the like.
I, GEORGE DEACON, of Lower Thrift Street, Northampton, in the County
of Northampton, Horticultural Builder, 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 invention relates to an improved apparatus for the adjustment of skylights
fanlights and the like, which consists of a long screwed bar pivoted to a plate, the
said long straight bar is cut with a male thread of any suitable length on the
outside, this said male screw operates in a female screw cut in a ball enclosed and
working loosely inside a cog or other wheel, the said cog or other wheel is in two
halves in centre part and screwed or rivetted together. If preferable the pulley
may be mounted in bearings on any suitable frame, and the said pulley may be
operated by cog teeth (known as a crown cog wheel) fixed on the face of a pulley
mounted on a spindle which revolves in parts of the frame. The ball is provided
with one or more projecting pins or rockers to work in a seating cut in each half
of the cog wheel herein before described.
And in order that my invention may be thoroughly understood, I now proceed

page_text: to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is an elevation of the pulley wheel and pivoted screwed bar; the long
screwed bar is shewn broken off.
Fig. 2, is the inner side of each halt of the pulley wheel.
Fig. 3, is a side view of the oscillatory ball.
Fig. 4, is a view of the apparatus complete drawn to a small scale.
In carrying my invention into practice I provide a pulley a a divided into two
halves and in the inner side of each half I provide a ball seating i and two centre
pin seatings j. Each of the seatings are constructed of sufficient size so as to
permit the oscillatory ball d to move in any direction required by the long straight
screwed bar f. The straight barf which is pivoted to a plate g is provided with a
quick male screw for operating in the female screw cut in the centre of the
oscillatory ball d. Each of the two parts of the pulley a a have on the outsides
bearings ee for the purpose of mounting the same in a suitable frame as in
Fig. 4.
The two parts of the pulley a a are fixed together rigidly by screws in the
holes h.
The oscillatory ball d as in Figs. 1, and 3, is constructed of such a shape with
two rocking or centre pins c and making a backward and forward movement in
the seatings j.
An endless cord 6 is used to work the apparatus which runs over the pulley a a.
To apply the apparatus to a skylight; I fix the pivoted plate 9 by countersunk
screws onto the hinged glazed sash, and the frame I fix also by screws onto the
sasb-frame of the skylight at any convenient position.
Having now particularly described and ascertained the nature of my said iuven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a fanlight or skylight apparatus, the combination of the pulley a a
bearings e ball seatings i centre pin seatings j and the oscillatory ball d centre
pins with the screwed bar and the pivoted plate g, substantially as herein
described and according to the accompanying drawing.
2. In an apparatus for the adjustment of fanlights and skylights, the combination
of the parts described in the above specification for the purpose specified.
Dated this 15th day of February 1897.
