PROVISIONAL SPECIFICATION.
Improved Manufacture of Hinges.
I, HENRY SCHLUND, of Aston Lane, Perry Barr, Birmingham, in the County
of Warwick, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the manufacture of hinges and particularly those known
as solid butt hinges. In the manufacture of hinges it has always been the object
to produce the metal in such suitable shape that the making and finishing of the
hinge can be effected with as little loss of waste material and time as possible and
that is the object I at present have in view; hitherto however success in this
direction has been attained only in a very limited degree.
The usual form of the plate or blank from which the hinge is to be made was
such that having considerably more metal on one side generally along one edge
than on the other it became very difficult to produce a long straight strip whether
by casting which is undesirable on account of blow-holes and irregularities or by
rolling or otherwise.
as a
In carrying out my invention I form the strip or blank for the hinges preferably
long strip which may be cast drawn rolled or pressed the strip being in the
form of a flat straight strip with a central ridge upon one side for forming both
leaves of the hinge out of one piece of metal.
The strip is afterwards cut up into the required pieces for the hinges.

COMPLETE SPECIFICATION.
Improved Manufacture of Hinges.
I, HENRY SCHLUND, of Aston Lane, Perry Barr, Birmingham, in the County
of Warwick, 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 :-
This invention relates to the manufacture of hinges and particularly those known
as solid butt hinges. In the manufacture of hinges it has always been the object
to produce the metal in such suitable shape that the making and finishing of the
hinge can be effected with as little loss of waste material and time as possible and
that is the object I at present have in view; hitherto however success in this
direction has been attained only in a very limited degree.
The usual form of the plate or blank from which the hinge is to be made was
such that having considerably more metal on one side generally along one edge
than on the other it became very difficult to produce a long straight strip whether
by casting which is undesirable on account of blow-holes and irregularities or by
rolling or otherwise.
In carrying out my invention I form the strip or blank for the hinges preferably
as a long strip which may be cast drawn rolled or pressed the strip being in the
form of a flat straight strip with a central ridge upon one side for forming both
leaves of the hinge out of one piece of metal.
The strip is afterwards cut up into the required pieces for the hinges.
In the accompanying drawings
Fig. 1 shows a section of the blank and

page_text: A represents the ridge and B are the leaves or flat portions of the hinge.
In Figure 1 the ridge A is shown projecting upon one side only of the leaf
portion B but it will be understood that if desired this may project also upon the
other or under side, of B; as a rule, however the form shown in the drawing is
what would be used. It will be readily observed that by my invention a strip of
uniform section is obtained the thick, portion A being in, the centre of the strip
and the leaves or thinner portions B balancing each other, one on each side of A.
By this means I am enabled to produce a strip or blank of substantially uniform
section throughout whether it be cast or rolled thus effecting a great improvement
upon the methods of hinge manufacture hitherto adopted.
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. A. hinge blank or strip having a central ridge such as A and a leaf or flat
portion on each side of it substantially as described and illustrated in the accom-
panying drawings.
2. The method of producing a straight hinge blank or strip which consists in
forming it with a central ridge and side leaf or flat portions substantially as
described and illustrated in the accompanying drawings.
