Year: 1896

page_text: We, CHARLES FITCHETT GRAY of 139 Pershore Road in the City of Birmingham,
Brassfounder, and HARRY WILSON of 94 Main Street, Birmingham aforesaid, Pattern
Maker, do hereby declare the nature of this invention to be as follows:-
We carry out our invention by having a screwed spindle working in bearings on a
plate attached to the fanlight frame. At the head of this spindle is a bevelled cog wheel
working into another bevelled cog wheel carried on a bracket which is attached to or
independent of the plate. This second cog wheel has attached to it in front a grooved
pulley over which the cords work for opening and closing the fanlight. A cranked
arm working on a screwed boss which travels on the screwed spindle connects the action
with the fanlight. We make this cranked arm detachable by the use of a loose screw-
pin at each of its two ends, and the other parts are made reversible or otherwise so
formed that after the detachment of the arm the parts can be placed onto fanlights
which are hinged or pivotted to open in various positions.

We, CHARLES FITCHETT GRAY of 139 Pershore Road in the City of Birmingham,
Brassfounder, and HARRY WILSON of 94 Main Street Birmingham, aforesaid, Pattern
Maker, 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:-
We carry out our invention by having a screwed spindle working in bearings on a
plate attached to the fanlight frame. At the head of this spindle is a bevelled cog
wheel working into another bevelled cog wheel carried onto a bracket which is
attached to or independent of the plate.
This second cog wheel has attached to it in front a grooved pully over which the
cords work for opening and closing the fanlight. A cranked arm working on a
screwed boss which travels on the screwed spindle connects the action with the
fanlight.
We make this cranked arm detachable by the use of a loose screw pin at each of
its two ends and the other parts are made reversible or otherwise so formed, that
after the detachment of the arm the parts can be placed onto fanlights which are

page_text: hinged or pivotted to open in various positions. A great advantage in this our con-
struction of fanlight openers is its compactness and slight projection from the face
of the fanlight and frame.
We will now more fully describe this our invention by the aid of the accompanying
sheet of drawings upon which similar letters of reference on the several figures
relate to similar parts.
Fig. 1 is a front view of one of our fanlight openers.
Fig. 2 is a side view shewing its position when the fanlight is closed, and
Fig. 3 is a view of the reverse side, showing its position when the fanlight is
partly open.
a
A is a screwed spindle working in bearings B on the plate C attached to the
fanlight frame D. At the head of the spindle A is a bevelled cog wheel E
working into a bevelled cog wheel F which is carried by and revolves on
pin or spindle passing through the hollow shaft G, the spindle thus acting as a
bracket off the top of the plate C, or from an independent plate. This cog wheel F
has attached to it the grooved pulley H over which the cord I, I, works to open and
close the fanlight, the cord is kept in position by passing it through an opening or
openings in the bottom plate J¹ of the pulley frame J. K is a travelling screwed boss
on the screwed spindle A with an arm 1. sliding on one or both sides of the steadying
rib M. Or instead of the rib a groove may be formed in the plate C for the arin L
to slide in.
The cranked arm N, N¹ is connected to the boss K at O and to the fanlight at P,
and thus connects the action with the fanlight.
Pulling the cord I Figs. 1 & 2 rotates the, screwed spindle A in the direction to
cause the travelling screwed boss K to travel downwards, thereby acting upon the
curved arm N and opening the fanlight (see Fig. 3). Pulling the cord I Fig. 3
gives the reverse action to the travelling boss K and closes the fanlight, as at Fig. 2.
In order to adapt the fanlight openers to the varying positions requisite to suit
various constructions of fanlights and the like, we make the curved arm N detach-
able by the use of screw pins at O, O', and the other part N' reversable.
Making the cranked arm N detachable also enables us to substitute other arms
of different lengths when required, without altering the parts attached to the
frame.
The travelling boss K has a stud R on it, on each side, to either of which the
cranked arm N may be attached, or a cranked arm may be connected on both sides,
so that the same opener may be used for a right hand or left hand fanlight or for
both together, or for a series of fanlights connected together in any convenient
manner.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed, we declare that what we claim is:
1. In fanlight openers, the combination of bevelled cog wheels E and F, pulley H,
and screwed spindle A, for the purpose of actuating a screwed boss K which is
connected by a cranked arm to a hinged or pivotted fanlight.
2. The steadying rib M for the purpose of steadying and keeping in its true position
the travelling boss K as applied to fanlight openers.
3. Making the cranked arm which connects fanlights to their openers detachable
so as to readily adjust the opener to the varying positions required in applying it to
various constructions of fanlights.
