CHARLES HOLLAND JAMES Bridgeman Street Walsall Ironfounder, do hereby
declare the nature of this invention to be as follows:-
An improved method of constructing iron hinges (known as cast iron butts)
having pivots unremovable & unseen.
I cast my two sides of the hinge, I then cut out clean with cutters the
intersecting joints, further I do not cast my "double" side of the hinge, on to the
single " side as is usual but I cast each side separately.
<<
In constructing the pivot arrangement of the hinge, I introduce this novel
method of joining the two sides of the hinge.
I cast or drill the pivot hole lengthwise of the hinge joint but not entirely
through the half of the hinge called the double side but through the half of the
hinge known as the single side, I cast or bore a hole right through after putting
my two sides together, I insert the pivot wire and push it right down to the bottom
of the stopped end; the length of my pivot is such that when inserted, it sinks for
an "of an inch within the mouth of the pivot hole.
I then plug this pivot hole with a plug or screw. By this means the pivot is
entirely hid, the cast up end protecting it at the bottom and the plug or screw at
the top.
The invention is intended to apply to all descriptions of cast iron hinges.
An Improvement in the Construction of Cast Iron Hinges.
1, CHARLES HOLLAND JAMES, of Bridgeman Street Works, Walsall in the
County of Staffordshire, Ironfounder, do hereby declare the nature of this inven-
tion 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 an improved method of constructing cast-iron hinges of
the kind known as ordinary cast-iron and malleable cast-iron "butts" or "Haps."
Its chief object is to cheapen the cost of production of, and at the same time to
improve the manufacture of, such hinges while providing means for removing the
pin or pivot, and also for the concealment of the same within the hinge.
Upon the accompanying sheet of drawings illustrating a hinge constructed in
accordance with my invention,
Figure 1 is an elevation of the hinge, the "Haps" or "butts" being shewn
open;
Figure 2 is an elevation, partly in section, of the "double" side of the

page_text: In carrying out my invention I cast the two sides A B of the hinge separately,
and mill or otherwise form therein recesses a b, these operations being performed
by any suitable methods.
I then drill the pivot hole C through the joints of the sides of the hinge
longitudinally as shewn on Figures 2 and 3, care being taken not to drill entirely
through the "double" side.
The sides are then placed together so that they may be connected by the
insertion of a suitable metal wire or other pin or pivot D, this pivot being pushed
right down so as to enter the recess in the end joint c of the "double" side, this
end joint acting as a stop for the pivot. The length of this pivot is such that after
being inserted in the sides of the hinge a space is left at the entrance to the pivot
hole, this latter being then plugged with a suitable screw or plug E by means of.
which the pivot is entirely concealed and secured within the hinge.
The plug may be formed of a "screw-plug" capable of being screwed into the
pivot hole eo that, if desired, it can easily be withdrawn by means of a slot formed
in its head. Any other form of plug may, however, be used.
The pivot and screw-plug may also be formed in one piece, whereby on
unscrewing and removing the pivot of the hinge of a door, for example, the door
may be taken down without detaching the hinge from the woodwork.
The hinge is then finished by squaring the ends and sides and polishing, as
required.
In lieu of drilling the pivot hole it may be formed in the sides of the hinge
during the casting of the same.
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. In the construction of cast-iron hinges or "butts," forming a pivot hole in the
sides of the hinge, said pivot hole extending entirely through the "single" side of
the hinge but not entirely through the "double" side, and securing a pivot within
said pivot holes by means of a plug, substantially as described.
2. In cast-iron hinges the use of a plug E for the purposes and as described with
reference to the accompanying drawings.
3. In cast-iron hinges the combination of a pivot D inserted in pivot hole C,
with a recessed end joint c and plug E acting as stops for the pivot, for the
and as described.
purposes
