punched through it before the metal has reached an inconvenient length and a wire
inserted and the metal drawn or rolled down onto the wire by universal collapsing

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Hinges.
1, 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:—
In carrying out this invention I prefer to form the strip or blank for the hinges
preferably as a long strip which may be cast drawn or rolled the strip being in the
shape of a flat straight strip with a central ridge upon one side.
The metal may be cast into a convenient form with a hole in it or it may be
drawn rolled or pressed into a convenient form and a hole subsequently drilled or
punched through it before the metal has reached an inconvenient length and a
wire inserted and the metal drawn or rolled down onto the wire by universal
collapsing dies or other suitable means.
The strip is afterwards cut up into required pieces for the hinges.
In the accompanying drawings
Fig. 1 is a section of the blank showing the hole without the wire.
Fig. 2 is a similar view showing the wire in position and
Fig. 3 is a plan or face view of a portion of the blank showing the wire projecting
at one end.
A is the central ridge in or through which the hole D is formed in any suitable
manner as during the casting if the strip be cast, or during the rolling or pressing;
or the hole may be subsequently drilled or punched before the strip has become too
long to be so dealt with. B represents the wire which may be inserted during any
desired part of the process of manufacture and C are the leaf or flat portions of the
blank or strip. After the wire is inserted the metal may be drawn down on to the
wire by universal collapsing dies or other suitable tools such as those moving
parallel to the axis of the wire.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. A hinge blank or strip having the hinge axis or wire cast rolled pressed or
otherwise produced in it during the manufacture of the said blank substantially as
described and illustrated in the accompanying drawings.
2. The method of manufacturing hinge blanks or strips which consists in the
insertion of the axis or wire during the formation of the said blank or strip.
