PROVISIONAL SPECIFICATION.
A Safety Gas Bracket for Use in Lunatic Asylums, Prisons, or
other Public Buildings.
JAMES MILNE, Engineer, Milton House Works, Edinburgh, do hereby declare
the nature of this invention to be as follows:-.
The bracket is so designed that it has no projecting part on which a person could
hang himself or do himself bodily damage. The gas is turned on & off by means.
of a loose key, and the projecting arm is jointed so that when any weight is hung
upon it, it falls to a vertical position. This arm is made quite smooth and slightly
tapered, so that nothing can be easily attached to it, but will slip off by its own
weight when in a vertical position. The bracket is so constructed that when the
pulled down, the gas is shut off, and cannot be turned or again by elevating.

A Safety Gas Bracket for Use in Lunatic Asylums, Prisons, or
other Public Buildings.
I, JAMES MILNE, Milton House Works, Edinburgh, Engineer, 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 the construction of a gas bracket of such a form that the
gas can only be turned on by means of a key; the object of it being that a suicidally
disposed patient cannot make use of it to hang himself from, and that if in
endeavouring to do so he turns off the gas he cannot possibly turn it on again.
The stopcock is so constructed that upon the arm being pulled down it shuts off
the gas which thereupon remains shut off, no matter whether the arm is raised again.
or not, until the key is employed to turn it on again.
Figures 1 & 14 shew the bracket with the gas turned on. The arm A is in a
horizontal position. At the base of the arm close to the joint B, I form a small
projection C. Upon the key of the stopcock D I form another projection E.
Figures 2 & 24 shew the arm half pulled down. The projections C & E have.
come in contact and the stopcock has begun to close.
Figures 3 & 34 shew the arm fully pulled down and the stopcock entirely closed.
Figures 4 & 44 shew the arm again elevated to the horizontal position, but the
stopcock still closed and requiring the key to turn the gas on.
I form the head of the stopcock square, oval, D shaped, or any shape that cannot.
easily be turned without a key to fit.
The gas can only be turned on when the arm is in a horizontal position..
Figures 3 & 34 shew the stopcock locked by the arm when pulled down.
The form of the bracket is substantially as shewn. The joint and stopcock are
covered by a smooth rounded cover F having only sufficient openings for the arm.

from base to point.
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
The method whereby the gas is shut off when the arm of bracket is pulled
down and remains shut off until the necessary key is used to turn it on.
