Improvements in the Manufacture of Hinges.
We HENRY HUNT BRAND of Wolverhampton, Galvanized iron Manufacturer, and
WILLIAM HENERY HARPER, of Green Lanes Wolverhampton, Oliversmith, both in the
county of Stafford do hereby declare the nature of this invention to be as follows :-
This invention relates to the manufacture of wrought iron or steel hinges, and has
for its object their manufacture from wrought iron or steel tubes. In many manu-
factures where such tubes are used there is a large quantity of waste ends for which
there seems to be no good use and which consequently have to be re-worked up.
These pieces in particular however we take, and by suitable tools, such as rolls, dies,
cutting, shearing, drilling, and other finishing tools, we reduce or transform the
tubular sectional form into the (half) hinge sectional form, and then by suitable
operations, form, and unite together the (halves) or parts forming the complete
hinges.
The operations necessary to thus manufacture the hinges out of wrought iron or
steel tubes, may be accomplished either while the tube is heated, or when cold,
according to the nature and requirement of such operation, or, the quality of the
material.

We HENRY HUNT BRAND of Wolverhampton, Galvanizing Iron Manufacturer, and
WILLIAM HENERY HARPER, of Green Lanos Wolverhampton, Oliversmith both in the
county of Stafford 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 wrought iron or steel hinges, and has
for its object their manufacture from wrought iron or steel tubes in the manner
hereinafter described, and by which method we are enabled to manufacture them from
short lengths or scraps of tubos. In many manufactures where such tubes are used
there is a large quantity of waste ends, for which there seems to be little or no good
use, and which consequently have to be re-worked up. By our invention however we
aro enabled by the method of manipulation or operations herein explained to transform
the tubular form of section, into the (half) hinge sectional form, and further to
complete therefrom the manufacture of hinges.

The operations necessary to thus manufacture the hinges from wrought iron or steel 1
tubes may be accomplished either while the tube is heated, or, when cold, according
to the nature and requirement of such operation, or the quality of the material.
In order to explain more clearly in what manner this our invention is to be per-
formed, we have appended hereunto an illustrative sheet of drawings upon which are
figures and lotters of reference, like letters referring throughout the several views to
the same thing or part.
Fig. 1 shows a length of tube cut off to form the one half of the hinge.
Fig. 2 shows a section of "oliver" or press tools by which at one operation the
piece a may be made into the hinge section.
Fig. 3 shows the tools in position having formed the piece into the hinge section.
Fig. 4 shows two halves or parts formed ready to complete the hinge.
Fig. 5 shews a plan of the hinge complete.
We first cut the tubes a to the same length that the hinge is required to be. This
piece a is then heated in order to increase its malleability, and then placed in a bottom
tool b, similar as seen in Fig. 2. A top tool is brought down with a sharp blow,
which forces the piece a, into the sectional shape as seen in Fig. 3. These tools
would be used in what is commonly known as an "oliver" or similar sudden
action press.
The sectional form as produced by the operation shewn in Fig. 3, would then be
further treated in the ordinary manner of manufacture, that is, such portions of the
tubular part at d, d, being cut away in order to form pairs, also the rivetting up or
securing of the joint pin, and the providing of holes e, e, e, or other processes of
filing, grinding &c. in order to complete their manufacture, similar as seen in
Figs. 4 & 5.

We are aware that hinges have already been formed from tubes, by the "drawing"
process, that is, drawing, reducing or compressing the tube by pulling it through a
drawing die into the required sectional form, and afterwards cutting the lengths off,
whorewith to make the hinge. In order to produce iron or steel hinges this method
would be impracticable and inconvenient, and require also that the tubes should be of
some considerable length, but by this our method of manufacture the class of tools
required and their wear and tear are of a nuch cheaper character than by the drawing
process, and further by reason of their being cut to length before heating and forging,
short scrap ends of tubes may be ntilized.
We may in some instances heat the pieces a before forging into the final sectional
shape as shewn in Fig. 3, to a welding heat, so that when subjected to the final
shaping they may be welded more or less; in such cases we may adopt if necessary
two operations to produce such results.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed we declare that what we
claim is
The improvements in the manufacture of iron or steel hinges as herein described
and illustrated upon the drawings Figs. 1, 2, & 3, that is to say the forming of hinge
halves or parts, from cut lengths of iron or steel tubes, by the forging process or
processes, with tools b & c, or such similar tools, as and for the purposes specified.
