Analogous Purposes.

page_text: Date of Application, 14th Feb., 1888
Complete Specification Left, 4th Sept., 1888
Complete Specification Accepted, 12th Oct., 1888
also to other Analogous Purposes.
I, FRANCIS JOSEPH JAMES GIBBONS, of Saint John's Works, Church Lane
Wolverhampton, in the County of Stafford, Lock Manufacturer do hereby declare
the nature of this invention to be as follows:-
Before describing the nature of my improvements I may first state that the
ordinary hanging centre-plates for Fanlights are plates having angular slots with
circular bottoms, therein, and which are screwed on either side the Fanlight Sash,
whilst on either side the Fanlight frame is screwed a plate having a centre-pin
thereon, and these centre-pins being placed in the angular slots, the weight of the
fanlight forces them to the bottom of the same, wherein they turn on the opening
of the fanlight.
It has however been found that when fanlights hung on the above principle have
been left open, a strong gust of wind causes them to rattle, and sometimes to lift
the centres out of the angular slots in the plates, and it is this defect which my
improvements are intended to remedy.
I therefore employ pieces of metal fitting into these angular slots and secured to
the front edge by means of screws. These pieces of metal are of a semi-circular
form at the ends and fit upon the centre pins, thereby remedying the defects referred
to above.
In lieu of the angular slots I may preferably employ horizontal slots with semi-
circular recesses at the bottom for the reception of the centre-pins, and in this case
should also employ pieces of metal fitting into the horizontal slots and secured thereto
as before described. I may also employ springs or any other convenient arrangement
for preventing the centre-pins from rattling or rising from their bearings, inasmuch
as the principle is open to various modifications.

Improvements in Hanging Centre Plates for Fanlights, Applicable
also to other Analogous Purposes.
I, FRANCIS JOSEPH JAMES GIBBONS of Saint John's Works Church Lane
Wolverhampton in the County of Stafford, Lock Manufacturer, 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 :-
Before describing the nature of my improvements I may first state that the ordinary
hanging centre plates for fanlights are plates having angular slots with circular
bottoms therein, and which are screwed on either side the fanlight sash, whilst on
either side the fanlight frame is screwed a plate with a centre pin thereon, and these
centre pins being placed in the angular slots, the weight of the fanlight forces them

It has however been found that when fanlights hung on the above principle have
been left open, a strong gust of wind causes them to rattle, and sometimes to lift the
centre pins out of the angular slots of the plates, and it is this defect which my
improvements are intended to remedy.
I therefore employ pieces of metal Fig. 2-fitting into horizontal slots or openings
and secured to the front edge by means of screws as shewn at Fig. 3-These pieces of
metal are semicircular in form at the ends-A-Fig. 2 and fit upon the centre pins,
thereby remedying the defect referred to.

Having now particularly described and ascertained the nature of my inven
tion, and in what manner the same is to be performed, I declare that what I
claim is
1-The construction of hanging centre plates for fanlights substantially as herein
described and illustrated by the accompanying drawings.
2-The insertion of pieces metal into slots or openings, the same fitting upon the
centre pins, and being secured in position by screws, also substantially as herein
described and illustrated by the accompanying drawings.
