Improvements in Fanlight and Skylight Openers.
We CHARLES FITCHETT GRAY of Exeter Street, Birmingham, Manufacturer,
and HARRY WILSON of 137 Ombersley Road, Birmingham, Pattern Maker, do
hereby declare the nature of this invention to be as follows:-
In this invention we obtain direct action between the stay bar and the spiral
cog on the pulley and require no further catch or check to hold the stay bar
firmly in position.
It is constructed as follows.
Upon the stay bar are teeth, cut slightly eccentric so that when coming in contact
with the spiral worm of the cog they will follow the line thereof and have an equal
bearing thereon.
The other portion consists of a bracket with two arms between which arms works
a combined pulley and spiral cog, immediately below which are piercings or openings
through the arms allowing of the toothed stay bar to travel so that the worm of
the spiral cog will work in the teeth of the stay bar with a steady bearing and will
securely hold or lock it at any desired point.
The two arms are connected by a bridge immediately below the point where the
stay bar travels, so that it may act as a further support thereto and it may be
formed with sides so as to assist in steadying the stay bar.
Upon the lower portion of the bracket, on each side projecting eyes may be
formed to act as guides to the cord.

Fig. 1. is a side view of one of our openers as applied to a faulight and Fig. 2 is
a pian of the same.
We will now describe more fully our invention.
Upon the stay bar a. are teeth d. d. cut slightly excentric so that when coming

page_text: in contact with the spiral worm 62 of the cog b they will follow the line thereof
and have an equal bearing thereon.
The bracket portion e has two arms f, f, between which arms f, f works the
spiral cog b, and combined with or rigidly attached to this spiral cog b is the
pulley, and immediately below the spiral cog are piercings or openings, through
the arms, allowing of the toothed stay bar a travelling so that the worm 6 of the
spiral cog b will work in the teeth d of the stay bar a with a steady bearing and
will securely hold or lock it at any desired point.
The two arms, are connected by a bridge g, immediately below the point
where the stay-bar a travels so that it may act as a further support thereto and it
may be formed with sides g¹ so as to assist in steadying the stay bar a.
Úpou the lower portion of the bracket e, on each side thereof, projecting eyes h
may be formed to act as guides to the cord k which passes over the pulley portion b
of the combined cog and pulley.
We wish it to be understood that we do not confine ourselves to the exact form
of the parts as illustrated as it will be obvious that slight variations therein will be
necessary to accomodate the openers to the various ways in which fanlights and
skylights are hung in their frames.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
1. In fanlight and skylight openers a spiral cog having a direct action upon the
toothed surface of the stay bar.
2. In fanlight and skylight openers a bridge, with or without sides, acting as a
support and guide to the stay bar.
