PROVISIONAL SPECIFICATION.
Improved Apparatus for Hanging Doors and Gates.
I, JAMES RUMGAY, of Tasman Street, in the City of Wellington, in the
Colony of New Zealand, Joiner, do hereby declare the nature of this invention to
be as follows:-
The objects of my invention are to hang doors and gates hereinafter called doors
in a firm and substantial manner and so that they may swing in a semicircle in order
to open inwards or outwards but may always have a tendency to return to a closed
position by the action of the weight of the door itself.
To perform these objects I prefer to dispense with the ordinary hinges and hang
the door on top and bottom pivots projecting beyond the upper and lower edges of
the door.
In order to place these pivots in their sockets I make the upper one in the form
of a sliding bolt so that it may be fixed flush with the upper edge of the door but
when in its place it can be pushed or slided into its socket and prevented from
returning by a pin or bolt. The bottom pivot I cast on a grooved shaped casting
(by preference) so as to fit upon and grasp the bottom edge of the door. This
pivot fits into a socket formed in a casting which is firmly fastened to the floor or
foundation and has cast upon it inclined planes upon which a roller revolving on the
pivot casting rolls upward and downward so that on opening the door in either
direction the said door is lifted upwards but when in its normal or closed position
it is at the bottom of the two inclined planes. Notches or recesses are formed on
the inclined planes in which the rollers may rest and thus retain the door in any
desired position.
As the door rises in opening it is necessary that it should not quite reach the
frame at the top but when desired I fix an elastic substance or elastic tube to the
top of the door so that the slight gap may be filled and draught prevented.

COMPLETE SPECIFICATION.
Improved Apparatus for Hanging Doors and Gates.
I, JAMES RUMGAY, of Tasman Street, in the City of Wellington, in the
Colony of New Zealand, Joiner, 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 object of my invention is to provide a method and apparatus by which doors
and gates (hereinafter called doors) can be hung in position in a firm and substantial
manner, and so that they may swing freely in order to open outwards or inwards,
but will always have a tendency to return automatically to a closed position by the
action of the weight of the door itself.
My invention is illustrated on the accompanying sheets of drawings on which,
Figure 1 is a side elevation of the upper and lower portions of a swinging door
as fixed in position.

Figure 2 is an end view of the same.
Figure 3 is a plan of the bottom step or pivot together with the bottom door
bracket.
Figure 4 is a plan of an upper hinge when the door is fitted to a partition, or
where a top frame is not required.
Figure 5 is a side view of the same.
Figure 6 is a side view of an arrangement of hinge when the door has to be
secured to the outside of a post or framing.
Figure 7 is a plan of the bottom step or pivot.
Figure 8 is a side view of the same.
Figure 9 is a front view of the same.
Figure 10 is a section through the line B. C.
Figure 11 is a plan of the bracket or socket fastened to the lower edge of the
door.
Figure 12 is a side view of the same.
Figure 13 is an end view of the same.
Figure 14 is a front view of the travelling roller.
Figure 15 is an end view of the same.
Figure 16 is a side view of the upper bracket which is fastened to the door by
means of screws.
Figure 17 is a plan of the same.
Figure 18 is an end view of the same.
Figure 19 is a side view of the sliding pivot.
Figure 20 is an end view of the same.
Similar letters indicate like parts in all the figures.
(a) is the bottom step firmly fixed to the floor or foundation, and carrying a
pivot (a¹) on which the door (A) turns either way in opening and shutting, and on
which the door is able to move slightly upwards and downwards.
(b) is a bracket fixed to the bottom of the door (A) by means of screws, and
having a socket (61) which fits the pivot (a¹) and turns upon the same. This
bracket (b) is fitted with a roller (62) which takes the weight of the door, and rolls
upon and up or down the inclined planes (63) according as the door is opened or
shut in either direction. (64) is a recess in which the roller (62) rests when the
door is closed, and which recess can be provided with rubber so as to receive the
weight of the door quietly and without shock. (6) are two recesses one on either
side of the door (A) in which the roller (62) rests after ascending the inclined
planes (63) and when the door is fully opened in either direction.
The back part of the bracket (6) is rounded underneath at (66) for about half
its length, and this convex surface fits into a corresponding concave surface in the
bottom step (a).
(c) is a bracket fastened firmly to the upper angle of the door (A) by means of
screws, and (by preference) let into the same so as to be flush with the edges of the
said door.
(d) is a bracket which carries the upper pivot (d²) of the door (A). This
bracket (d) fits snugly into the inner angle of the bracket (c) and is secured by a
screw (d2) when in its fixed position so that the pivot (d') may turn freely in the
socket (e) formed on a plate (e), which is itself firmly fastened to the frame of the
door by screws (e²).
In the bracket (c) is formed a slot (c¹) so as to allow of the pivot bracket (d)
being lowered so as to release the pin (¹) from the socket (¹) when desired, and
enable the door to be readily removed. Moreover this arrangement of sliding
bracket is of great service when placing the door in position as it can be lowered
and then raised like an ordinary bolt into the socket (e), and be firmly fixed by the
countersunk screw (d2).
(f) is a bracket carrying a pin (d'); to which it can be hung to a bracket (¹)
fixed to a partition, leaving space between for the rise and fall of the door when my
improved apparatus is made use of.

page_text: (g) is a bracket which can be fastened to the top of a door and hung to the
bracket (9) fixed to the outside of a post or frame allowing the foot of the door to
be fitted as hereinbefore described.
It will be seen that in hanging doors on my principle a space is obliged to be
left near to the upper hinge, and for a few inches in length, to allow for the rise of
the door; but such space being small will not prove much inconvenience and can
be stopped by an elastic tube or elastic material fixed on the side of the door or
frame if desired. Moreover it will be further evident that doors may be made to
move in a complete circle if desired, and be hung in a vertical line drawn through
the center of the door; in which case four inclined planes instead of two as shewn
in the drawing may be formed on the step (a), and the door be made to revolve
as on a turnstile, but always returning to a closed position by the weight of the
door itself. The shoe or bracket (b) being in that case fitted with two rollers such
as (6) one on each side of the circle, and which will rest in recesses similar to (68)
when the door is closed.
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. In an apparatus for hanging doors, a bottom step (a) having inclined
planes (63) combined with a bracket (6) fitted with a roller or rollers (62), as and
for the purposes substantially as described herein and illustrated.
2. In an apparatus for hanging doors, a bottom step (a) having pivot (a¹)
inclined planes (6³) recesses (64) & (6) combined with a bracket (b) having
socket (6) and roller (62), as and for the purposes substantially as described herein
and illustrated.
3. In an apparatus for hanging doors, a bottom step (a) having a concave
surface to receive the convex surface (66) of a bracket (b) substantially as described
herein and illustrated.
4. In an apparatus for hanging doors, a top bracket (c) fitted with a sliding
bracket (d) having a pivot (d') combined with plate (e) and socket (e¹), substantially
as described herein and illustrated.
5. The whole combination and arrangement of parts constituting my improved
apparatus for hanging doors substantially as described herein and illustrated in the
accompanying drawings.
