PROVISIONAL SPECIFICATION.
Improvements in the Hanging of Doors.
I, EDWIN HAPPER KERTLAND, of 9, Chlorine Gardens, Malone Road, Belfast,
Ireland, Damask Linen Factory Manager, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the hanging or hinging of doors in such manner as to
ensure the automatic closing of the door without the use of springs, weights,
pneumatic cylinders, and other devices heretofore used as a means of closing
the door. The improved means hereinafter described also dispenses with neces-
sity for use of draft excluders, as the door will move over inequalities of floor
and return to its correct position as a closed door.
According to this invention I mount the lower portion of the door upon a pivot
which serves as the hinge to the lower portion of the door. The upper part of
the door is mounted upon a corresponding pivot hinge, but the latter occupies
a. position at some distance greater than the first pin from what as ordinarily
is the hinge edge of the door, so that when the door is opened its movement is
not parallel to the floor, but it makes a canting movement, and soon as released
naturally through gravitation returns to its original position.
The same arrangement of hanging applies to double doors or a door divided
down the centre, these will afford free access in either inlet or outlet directions
by simply pressing them open, and as soon as contact is removed from them they
automatically close, no fasteners, catches, or hand manipulation of door or doors
so hung being requisite.
Improvements in the Hanging of Doors.
I, EDWIN HAPPER KERTLAND, of 9, Chlorine Gardens, Malone Road, Belfast,
Ireland, Damask Linen Factory Manager, 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 the hanging or hinging of doors in such a manner
as to ensure the automatic closing of the door without the use of springs, weights,
pneumatic cylinders, or other devices heretofore used. The improved means here-
inafter described also dispenses with the necessity for use of draft excluders as
the door will move over inequalities of the floor and return to its correct position

page_text: as a closed door leaving very little space between the edges of the door and the
floor or door posts or frame. The invention is applicable to single or double or
folding doors.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the annexed drawings, in
which:-
―
Fig. 1 is a front elevation of a pair of folding doors hinged or hung according
to this invention, and closed.
Fig. 2 is a similar view to Fig. 1 but the doors are shewn open.
Fig. 3 is a sectional end view of the pivot hinge.
According to this invention I mount the lower portion of the door 1 upon a
pivot 2 which serves as the hinge to the lower portion of the door 1. The
upper part of the door 1 is mounted upon a corresponding pivot hinge 3, but the
latter occupies a position at some distance greater than the first pin 2 from what
as ordinarily is the hinge edge of the door 1 so that when the door is opened its
movement is not parallel to the floor, but it makes a canting upward movement,
and as soon as the door is released, naturally through gravitation returns to its
original and closed position.
The same arrangement of hanging applies to single doors or to double doors or
a door divided down the centre, and such doors will afford free access in either
inlet or outlet directions by simply pressing them open, and as soon as contact
is removed from them they automatically close, no fasteners, catches, or hand
manipulation of door or doors so hung being requisite.
Each pivot hinge 2, 3 is simply a single pin (see Fig. 3) cast to or forming
part of a clamp 4 which clips the edge of the door I and is fixed thereto by bolts
or set screws such as 5, 5, and the pin is received and works in a metal footstep
or socket 6.
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 improved method of hanging or hinging doors as and for the purpose
herein described and substantially as illustrated by the accompanying drawings.
