I, HENRY HAWGOOD, 135, Monton Road, Eccles, near Manchester, Commercial
Traveller, do hereby declare the nature of this invention to be as follows:-
The hinge is intended to combine a spring or springs to enable the door to
automatically close itself or to remain stationary when open at right angles.
A plate of metal is screwed into or upon the post, and another upon the door.
One of the plates has a bolt (or piece of metal) which passes through the
centre at right angles encased in a spiral spring and socket which is sunk into
the post or door behind the plate and affixed to same, one end of bolt has a
hole (or eye) pierced through (or otherwise) which just shows itself through
the plate when same is fixed to work.
The other plate has a horizontal groove or bend across the centre, through
which from behind a pin passes perpendicularly close to the plate, this groove
or bend in the plate receives the end of bolt with pierced hole (or eye) attached
to the other plate and the pin passes through the hole (or eye) when drawn
from its spring socket, thus the two plates become connected as it were by a
kind of hook and eye.
The bolt passes through a spiral spring and the spring works between the
back of plate and head of bolt inside the socket, when the door is working
open either way, the bolt is forced partly out of its socket through the plate
and works like a piston in machinery and in itself performing duty as hinge
and door spring.
The door will remain stationary when closed, and also when open either way
at right angles, that portion of the bolt (or piston) which is lever'd by the action
of the pin plate from its socket, lays flush in the groove or bend of the pin
plate, and in this position the two plates sectionally form the letter T, the
hinge jamb remaining quite closed.
The advantages are, a combined spring hinge for hanging doors, simplicity
in manufacture, can be used on any door, casily fitted, the door will remain
stationary in three positions ciz. closed, or open outward or inward at right
angles, and the hinge may be used without the spring if necessary at lower
part of door.

Improvements in Hinges.
I, HENRY HAWGOOD, of 135, Monton Road, Eccles, near Manchester, in the
County of Lancaster, Commercial Traveller, do hereby declare the nature of
[Price Sd.]

page_text: 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 construction of hinges used for swing-doors and
the like and the object of the invention is so to combine a coiled spring or
springs with the hinge that the door will automatically close itself or will be 5
held open by the said spring or springs when opened to a right angle.
The invention will be readily understood on reference to the annexed sheet
of drawings and the following explanation thereof.
Fig. 1 is a vertical section of a portion of a door and doorpost showing the
application of my improved spring hinge thereto. Fig. 2 is a horizontal section 1
of the same showing the door in the closed position, and Fig. 3 is a similar
view showing the action of the spring hinge when the door is opened to a right
angle.
In these figs. is part of the door and part of the door post.
A plate of metal is affixed by screws to the door and another plate c* is
similarly attached to the door post.
The plate has attached to it or cast or formed in one piece therewith a
socket which is sunk into the post and in which fits the head or piston c*
of a bolte which passes out through the centre of the plate e, and inside the
socket is placed a spring f which is coiled round the bolt e and acts between
the head or pistone of the bolt and the inside of the plate c* so as to have
a strong tendency to keep the head e of the bolt in the position shown in
Figs. 1 and 2.
The other plate e is made with horizontal groove or bend across the centre
(see Fig. 1) between two curved or quadrant-shaped lugs g, through which lugs
and through a hole or eye in the bolt e is passed a pin in a perpendicular
position, which can easily be effected when the bolt e is drawn out a short
distance from its spring socket, and thus the two plates e and become
securely connected together.
The bolt e passes through the spiral spring f (as before mentioned) and
this spring works between the back of the plate and the head or piston e of
the bolt inside the socket and so long as the door a is closed the spring f is
fully expanded and keeps the door a in this position as shown at Fig. 2, but
as soon as the door is pulled or pushed open in either direction. the curved
lugs g acting against the plate will cause the bolt e to be drawn out of the
socket (as shown at Fig. 3) the piston or head compressing the spiral
spring f, and if the door is not thrown absolutely open to a right angle as
soon as it is released the re-action of this spring will cause the door to be closed
But if the door a
again, and the door will remain stationary when closed.
should be opened either way to a right angle (as shown at Fig. 3) then the
re-action of the spring f will keep it in the open position, that position of the
bolt which projects from the socket lies flush in the groove or bend of the
plate e above mentioned, the two plates c and being at right angles to each
other as shown.
The principal advantages of this improved hinge are that it forms an efficient
spring hinge for hanging doors combined with simplicity and economy of
manufacture, it can be used on any door, and it will keep the door stationary
in three different positions vist. either closed, or open outwards or inwards at
right angles.
It will be evident that in some cases only the upper hinge of the door may
be fitted with the improved spring arrangement, and that for heavy doors two
or more springs may be applied in a similar manner instead of one only as
shown on the drawings.
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:-
The combination of the plate e with its curved or quadrant shaped lugs g

page_text: and pin h, with the plate c³ socket d, bolt e with its head or piston e* and
spring constructed and acting substantially as herein before described and
represented on the drawings annexed.
