Iron Manufacturers 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 improvements in or relating to the manufacture of hinge
bands and the like and has for its object the production of the manufactured article of
relatively superior workmanship and at considerably less cost than has hitherto been
found to be practicable.
In the manufacture of binge bands and the like the practice hitherto adopted by
the Engineering industries has been to forge the hinge brackets and bands out of
plate or bar iron the pin or gudgeon holes being either formed on a mandril or
machine holed and except in special cases where careful forging with its consequent
expense for time and labour bus been necessary the article produced by such forging
process has been of a very rough and unfinished character. But according to our
invention we discontinue the forging process by manufacturing special rolls in which
we roll by the ordinary process bars of iron or steel or other equivalent material of
any required length of the particular section or sections required to form the hinge
brackets or bands adopted for use by engineers, shipbuilders and others.
Having thus produced the rolled bars of the section required we saw or shear such
bars to the length or depth required to adapt such sections for the purpose herein-
before specified. The several pieces thus sawn or sheared off the bar having been
punched or drilled out as found desirable and as hereinafter shown the manufactured
article produced by our invention as above set forth is then ready for use.
In further explanation of our invention we will now refer to the accompanying
drawings in which Fig. 1. represents a front elevation of a rolled steel or iron bar of
the section shown in the same figure. Fig. 2 shows in plan the application of this
rolled section as a hinge band say for a fire or other door the door with its stanchion

page_text: being shown in this Figure in sectional plan and Figs. 3 and 4 show in plan and
elevation a further application of our new or improved article of manufacture but it is
obvious that there are other ways or modifications in which our improved rolled
section may be applied either fixed as an eye-bracket or swinging as a hinge band and
throughout the following description similar letters in the specification and in the
drawings designate corresponding parts. Referring to Fig. 2 a is the rolled hinge
band mounted on the upturned end of the bolt & passing through a rebated stanchion c
and may represent a fire or other door rivetted to the hinge band a in the ordinary
way. Of course after having been rolled and sawn or sheared to the required depth
the hinge band or bracket prepared according to our invention must be holed by
machine punch or drill or otherwise to render it applicable for its designed purpose as
shown in Figs. 2 3 and 4.
In Figs. 3 and 4 the rolled band a may be arranged to swing on the rolled band a³
fixed or a may swing on a fixed or both may swing on a common pin their applica-
tions in any case remaining substantially as hereinbefore specified.
We may in certain cases utilise the rolled section shown in Fig. 1. as a girder for
constructive purposes as a strengthening mould in shipbuilding or other structures
and as louvres in certain cases but the section is not specially designed or adapted for
such purposes.
Having new 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 :-
(1) The improved method or process for the manufacture of hinge bands by the
operations of sawing cutting or shearing the same from a rolled iron or steel bar of
the requisite (Fig. 1) section substantially as and for the purposes hereinbefore
particularly set forth.
