COMPLETE SPECIFICATION.
Improvements in Door, Gate, and Flap Hinges.
I ALFRED DOMAN, of Terry Street, Kates Hill, Dudley, in the County of
Worcestershire, Agent, 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 :-
The purpose of my invention is to supply hinges for doors, gates or flaps, to
revolve upon a loose pin, which is secured and held in position by metal mountings,
instead of fixing the strap of the hinge on to a projecting hook to revolve upon.
Fig. 1. are two metal mountings A and B, to hold the loose pin C in an upright
position, upon which the strap of the hinge D revolves; the metal mounting B,
acts as a socket or cup to receive the bottom end of the loose pin C; and the other
metal mounting A, acts as a cap or socket to retain the loose pin C in an upright
position, whilst it revolves in the metal mountings A and B, the pin C, being thus
secured at the top and bottom by the metal mountings A and B, cannot give way
to the strain put upon the hinge whilst in use, so that the door or gate cannot
drag.
The metal mountings A and B, can be fastened on to the door or gate post by
screws, nails, bolts or rivets.
Fig. 2. is a side section of the loose pin and metal mountings as in Fig. 1.
Fig. 3. The metal mountings A and B, instead of being in two separate parts, as
in Fig. 1, are combined in one solid piece of metal; the top mounting A being
hollowed through to allow the loose pin C to drop through into the lower
mounting B, after passing through the eye or loop of the hinge strap D, as in
Fig. 1. The hole marked E passes through the front of the mounting A to
receive a screw, which when screwed through the front of the mounting and into
the groove F, of the pin, prevents the pin being withdrawn from its place, except
for the purpose of lubrication or fixing.
Fig. 4. is a side section of the loose pin and metal mountings A and B, as in
Fig. 3. and shows the loose pin C with a groove F, and the position of the screw H,
when screwed through the hole in the front of the metal mounting A, to keep the
pin C from being removed from its place, unless for lubrication or fixing.
All the parts of the hinge including the strap, mountings and pin, can be made
iu any kind of metal, either wrought, malleable or cast.
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 use of a loose pin C, as in Fig. 1, 2, 3 and 4, for the strap of the hinge
to revolve upon.
2. The use of a top and bottom metal mounting A and B, as in Fig. 1, and 3,
either made separately as in Fig. 1 and 2, or made in one solid piece of metal as
in Fig. 3 and 4, to hold the loose pin C in position, so as to equalize the strain
upon the whole of the pin C, and prevent it from giving way to the strain that may
be put upon the pin whilst in use, being so arranged to operate substantially, as
shown in Fig. 1, 2, 3 and 4.
Dated this Twelfth day of December 1895.
ALFRED DOMAN.
