Improvements in Hinges.
I, ADAMSON GEORGE WILD, of 10, Caxton Road, in the City of Sheffield, Engineer,
do hereby declare the nature of my invention to be as follows;-
My invention has for its object to prevent the two parts of a hinge from being
separated except in a pre-arranged position or positions.
In carrying out my invention, as applied to a simple butt hinge of two parts,
the joint of which consists of two butts situated one over the other for example.
In one butt I secure the joint pin which I prefer to make of a tapering form,
and provided with a projecting catchpiece or pin located at a short distance from
the underside of the butt, say for example one eighth part of an inch.
In the other butt I make a hole to correspond with and to receive the pin before
described, and provided with an annular groove an eighth of an inch from the
face, with an entrance for the catch piece or pin before described to pass into the
annular groove.
Thus the faces of the two butts come together the upper one bearing upon the
lower one, and the catch piece moving freely within the annular groove, the two
parts being capable of separation only when the catchpiece is opposite the entrance
before mentioned.

I, ADAMSON GEORGE WILD, of 10, Caxton Road, in the City of Sheffield, Engineer,
do hereby declare the nature of this invention and in what manner the same has
to be performed, to be particularly described and ascertained in and by the following
statement:.
-
My invention has for its object to prevent the two parts of a hinge from being
separated, except in a prearranged position or positions.
A hinge suitable for railway carriage doors and for other like purposes is shown
in the annexed drawings, like letters refer to like parts in any of the figures;
Fig. 1, shows the two parts of the hinge put together.
Fig. 2, shows the part A separated from part B, and a plan of same.
Fig. 3, shows part B, and a plan of same.
In carrying out my invention, as applied to a simple butt hinge such as shown

page_text: in the drawings, for example, consisting of two parts A and B, the joint of which
consists of two butts placed one over the other.
In the butt A3, is secured the joint pin A3, which is preferably made of a taper-
ing form and is provided with a projecting catch piece or a pin C, located at a
short distance from the underside or face of the butt A2, say for example one eighth
part of an inch.

In the other butt B2, I make a hole or recess B³, to correspond with and to receive
the pin A3, of the other part A.
It is provided with an annular groove D, say an eighth of an inch from the face
of the butt B2, with an entrance opening E, through which the catchpiece C, can
be passed into the annular groove D.
When the two parts A and B, are placed together in position, the faces of the
butts A and B2, come together, the upper one bearing upon the lower one, and
the catchpiece C, is capable of turning freely within the annular groove D.
The two parts are only capable of separation when the catch-piece is opposite
the entrance E.
Two entrances may be provided if desired.
Having now particularly described and ascertained the nature of my invention,
and in what manner the same is to be performed, I declare that what I claim, is :-
1. A hinge constructed in the manner as herein before described and shown.
2. In a hinge, the pin of one part provided with a catchpiece C, and the pinhole
of the other part provided with an annular recess D, to engage with the said catch-
piece, and having an entrance E, as hereinbefore described.
