PROVISIONAL SPECIFICATION.
Improved Device for Setting at any Desired Angle Fanlights
and the like.
THOMAE PERCY GRAHAM, The Studios, Bedford, Photographer, do hereby declare
the nature of this invention to be as follows
My invention consists in a construction of a device for the purpose of setting at any
desired angle or position doors, fanlights, dressing table glasses, black boards and
the like, which are hung on their centres and which are required at various times to
be set at a particular angle, or in a certain position, and the same is carried out in.
the following manner.
I construct a suitable casing of any suitable metal within which I provide a suitable
spring and ratchet. The said ratchet is secured by a screw or pin and is retained in
the desired position by the pressure of the said spring acting upon the back of the
said ratchet.
This forms the principal part of the mechanism, and this said casing contains two
flanges or brackets for the purpose of securing it to the framework within which the
door, fanlight, dressing table glass or black board works.
I next provide a piece of metal which contains two pins at right angles thereto, ono
pin is shorter than the other and is inserted in a hole made in one of the flanges
of the said receptacle and forms the centre upon which the glass, fanlight, dressing
table glass, black board revolves, while the shorter pin drops inside the said casing and
acts upon the ratchet.
The ratchet is preferably constructed of a semi-circular shape so as will allow the
pin, which is attached to the metal piece fixed to the glass, to describe the angle as is
equivalent and needful to the swing or play of the glass, fanlight, dressing table glass,
black board and thereby enabling the same to be set at such an angle as desired.
This arrangement will overcome many existing inconveniences and the advantage
of being able to readily set a glass, fanlight, dressing table glass, or black board.

Improved Device for Setting at any Desired Angle Fanlights
and the like.
THOMAS PERCY GRAHAM 27 Martins Lane Cannon Street London E.C. Photo-
grapher do hereby declare the nature of this invention and in what manner the
same is to be perforined, to be particularly described and ascertained in and by the
following statement :-
This invention consists in the construction of a device for the purpose of setting at
any angle or desired position, doors, fanlights, dressing glasses, black boards and the
like, which are hung on their centres and which are required at various times to be
set at a particular angle, or in a certain position and the same is carried out in the
following manner. I construct a casing of any suitable metal within which I provide
a suitable spring and ratchet. This said ratchet is secured by a screw or pin and is
retained in position by the pressure of the said spring acting upon the back of the
said ratchet. This forms the principal part of the mechanism. This said casing
contains two or more holes or I may use flanges for the purpose of securing it to the
framework within the door fanlight, dressing table glass, black board, or the like. I
next provide a piece of metal which contains two pins at right angles thereto; one

flange of the said casing and forms the centre upon which, the glass fanlight or black
board revolves. The shorter pin drops inside the casing and acts upon the ratchet.
The ratchet is preferably constructed of a semi-circular shape so as it will allow the
pin which is attached to the piece of metal attached to the glass, or its equivalent, to
describe the angle needful to the swing or play of the glass, fanlight, dressing table
glass or blackboard and thereby enabling the same to be set at such an angle as may
be desired. This arrangement will overcome many existing, inconveniences and the
advantages of being able to readily set glass, fanlights, dressing table glass, or black-
board will be at once understood.
Refering to the accompanying drawing, Fig. 1. is a plan of casing a, showing
ratchet b, spring c, ratchet pivot b¹. d, hole for longest pin. Fig. 2. shows plan of
piece of metal with longest pine and shorter pin f. Fig. 3. shows in plan a
modification of my invention in which a is casing b, b¹ ratchets & piece of metal
revolving in casing a and engaging with ratchets b, b. c spring. 9 square hole in b².
Fig. 4 piece of metal h, with square pin for entering hole g as shown in Fig. 5 and
also in elevation along line 1. 2. (Fig. 5) in Fig. 6. 1ª.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
(1) In a device for setting doors, windows, fanlights, dressing table glasses, black
boards and the like the combination and arrangement of the ratchet b spring c and
pins e and for square pin h¹ substantially as described and for the purpose set forth.
