PAR p
I, GEORGE HAMILTON KENRICK of West Bromwich, Staffordshire, Ironfounder, 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:-
This my invention relates to a new and useful improvement in metal hinges
commonly used for doors, boxes and the like articles, and it consists in forming the
wings of said hinges of such a shape as will permit of their being easily, quickly, and
firmly adjusted in position in the wood forming part of a door, box or other similar
article.
When adjusting a hinge it is customary to recess the same into a cavity formed in
the wood for its reception. In order to accomplish this object it is necessary to use a
chisel and other tools, the manipulation of which requires time and a certain amount
of practice.
By my said invention, a hinge may be readily and neatly fitted in place by any
inexperienced person unaccustomed to the general use of tools.
I now proceed to describe my said invention and the manner in which it is applied,
reference being had to the accompanying drawings and the figures and letters of
reference marked thereon: similar letters indicating like parts throughout.
Fig. 1 is a front elevation of my improved hinge. Fig. 2 is an elevation of my
improved hinge showing the manner in which it is adjusted in the wood-work.
Said improved hinge consists essentially of two wings A, A', pinned together in the
ordinary way at a-working on a central wire at a ; but which have their edges formed
of a semi-circular configuration as indicated at a', the centres of said semi-circles being
perforated with countersunk apertures a² for the reception of screws. The edges of
said semi-circular discs are slightly bevelled as shown at a³ which ensures their better
fitting in the recesses made for their reception in the wood-work.
The manner in which my said hinge is adjusted and retained in the woodwork is as
follows: :-
A common and well known form of bit, such as that shown in Fig. 3 is employed in
combination with an ordinary brace for the purpose of making three (or more, accord-
ing to the size of the hinge) circular recesses B, in the wood, the centres having been

page_text: previously marked with a pencil or pointed instrument inserted through the screw-
holes a. It will be readily understood that the recesses B should be of a depth equal
to the thickness of each wing of the hinge, and furthermore that the bit or brad should
be the same size or slightly smaller than the semi-circular edges of the wings:-it
will then be found that owing to their bevelled edges they will make a perfectly clean
and flush joint with the surface of the wood when the screws are tightly screwed
home. The dotted lines in Fig. 2 indicate pieces of wood 6 which must necessarily be
cut away with any convenient and suitable tool. .
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed I declare that what I
claim is :-
A hinge having its wings or such parts as are usually recessed in the wood formed
of a series of semi-eireles, the outline of which is made up of a series of segments of a
circle and such parts bevelled at their edges, all substantially as and for the purposes
hereinbefore set forth and illustrated in the drawings hereunto annexed.

I now proceed to describe my said invention and the manner in which it is applied,
reference heing had to the accompanying drawings and the figures and letters of
reference marked thereon: similar letters indicating like parts throughout.
Fig. 1 is a front elevation of my improved hinge. Fig. 2 is an elevation of iny
improved binge showing the manner in which it is adjusted in the wood-work.
