Improvements in Spring and other Wire Hinges.
I, SAMUEL SIDNEY BROMHEAD of 97 Newgate Street, London, E.C. Patent Agent,
do hereby declare the nature of this invention and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement :-
My improved Skeleton hinges are constructed of steel wire or partly of steel wire,
and partly of other metal, and preferably of round, or half round, or flat section.
Portions of the wire may be flattened, drawn out thin, or punched with screwholes.
Like all other hinges they consist of two parts, the pin with its supports, and the
knuckle or eye.
The pin may be prolonged, so as to support itself, or may be held by, or attached to,
supports added to it.
The knuckle of my hinges is formed by turning a wire round the pin, one or more
times, but so as to work freely thereon.
This wire is then extended so as to form the flap or strap which supports the
knuckle.
My steel Skeleton hinges may be made in various shapes, strengths, or sizes, and
be straight or cranked, plain or ornamental.
may
They may also be oxydised, nickel plated, coated with brass, bronzed or otherwise
externally finished.
My Skeleton hinges can be easily constructed to work with a spring action, so as to
form, a combined spring and hinge. To effect this, the wire coiled round the hinge
pin may be extended and tapered or drawn out to the size required to form a spring,
and placed at right angles, to the aforesaid hinge pin or in some other convenient
position, so that when the hinge is fixed on a door, the spring will exert a steady
resistance to the opening of the door.
If preferred, screw holes can be dispensed with in forming these hinges, and they
can be fixed, by means of staples to drive or to screw on.
These hinges can be easily and cheaply made, and will be from the nature and shape
of the material employed, exceedingly strong at the joint, which is the weak part of
most hinges. They are also especially suited for out door use.

D. D. are screwholes punched in the solid wire.
E. E. are extensions of the steel wire, tempered to form springs and tapered to give
the force required.
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. The employment of steel wire alone, or in combination with other metal in the
manufacture of hinges, and of hooks for the same, substantially as herein explained
and set forth.
2. The combination of wire hinges, and steel springs, so as to form spring hinges;
as herein explained and set forth.
