I, WILLIAM ALEXANDER MCKAY, of 54, Lambton Quay, Wellington, in the Colony
of New Zealand, Photographer, 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 doors and the like and its object is to provide means
whereby doors and the like and more particularly sliding doors may be more easily
opened and closed.
It is well known that sliding doors as at present constructed when being opened
or shut frequently become jammed or do not run smoothly, and that there is difficulty
in moving the same when they are of considerable weight.
In carrying out my invention I make the doors of any ordinary shape and size and
hang the same upon carriers hereinafter designated sectors which I prefer to have a
radius equal to the height of the door or nearly so. Means are provided to overcome
the tendency of the doors to settle with the sectors in a vertical position, that is, so
that a vertical line will cut the centre of the sector and bisect the arc of the same,
in which position the door would be partially closed.
In order that the invention may be readily understood I have illustrated the same
upon the accompanying drawings, which represent some of the forms in which the
invention may be used. All the illustrations shew elevations of the door viewed from
the inside of a building or structure.
Figure 1 is a view of a door open and hung upon two sectors of equal and large
size.
Figure 2 is a view of the same closed.
Figure 3 is a view of a door open and shewing sectors of small size.
Figure 4 is a view of a door closed and situated in a position where sectors may
extend beyond one side only of the doorway.
Figure 5 is a similar view with small sectors to effect the same purpose.
Figure 6 is a similar view but with the sectors inverted.
Figure 7 is a similar view, but operated with large sectors.
Figure 8 is a view of a sector co-operating with a roller.
Similar letters of reference indicate corresponding parts throughout the views.
Referring to the drawings and in the first place more particularly to Figures 1
and 2, the door (a) has a bar (a¹) to which is pivoted on the inside the sector (6) and
at the other end on the outside the sector (61), by their respective pivots (62 & 6³).
By thus hanging the door with one sector inside and the other outside the door is
more evenly balanced and prevented from rubbing detrimentally upon the wall of
the building or its guard plates (c). The door closes the door way (a²) when moved
in the direction shewn by the arrow Figure 1, when the bar (d), which is pivoted in
any convenient manner at (d) to the wall or floor of the building and slotted at (d²)
to engage the extension of pivot (6"), will swing with the sector (6) and its weight
[Price 8d.]

page_text: come the tendency of the sectors to settle in a vertical position as hereinbefore
mentioned.
In Figure 2, which shews the same door closed, the bar (d) is dispensed with and
flat faces (d³) are left at the extremities of the arcs of the sectors whereon they may
be at rest.
Figure 3 shews an arrangement of sectors used in positions where large sectors
cannot be introduced or would be inconvenient, as for example upon the doors of
tramcars, carriage doors and the like. In this case the sectors run upon rails (f &ƒ³)
fixed to the side of the structure or upon rails supported upon pillars fixed in any
convenient manner to the floor.
In Figure 4 the sector (6¹) is pivoted at (68) and runs upon the floor (g) as in
Figures 1 and 2, but the sector (b) is pivoted to the door at (6º) and is L shaped and
has its foot (b) running in a pit (g¹) below the floor (g), so that, when the door is
opened in the direction of the arrow, the doorway is left unobstructed.
In this case
a door may be hung upon the sectors and close against the corner of a building, the
bar (a) of Figures 1, 2, and 3 being dispensed with.
Figure 5 iliustrates another arrangement for effecting the same purpose, the door
being provided with a bar (a) which is extended beyond the door to carry a sector
(b), the sector (6') being pivoted to the door in the ordinary manner.
The sectors
run upon the rail (f) which is fixed to the wall of the structure. The stops (6)
prevent the sector (b) falling out of gear with its rail in case the door is accidentally
lifted.
Figure 6 shews a method of inverting the sectors illustrated in Figure 5, when the
nature of the structure requires such ◊ modification. In this case the bar (a) is
fixed at or near the middle of the door and the rail (^^) is fixed to the door above the
sector (6) and both sectors are pivoted to the rail (a³).
It will be obvious that the forms of sectors shewn in the other figures may be
inverted by simple modifications similar to those described in reference to Figure 6,
and that where the door overhangs as in Figures 5, 6, and 7 the overhanging weight
of the door must be sufficient. to keep the sector to its work upon the rail (f).
Figure 7 shews another arrangement where large sectors are introduced to hang
a door closing against the corner of a building or other position where sectors can be
used on one side only of the door. The sector (b) is pivoted at (68) to the side of the
structure and runs upon the bar (a³) fixed to and extending from the door. The
sector (6) runs upon the floor of the structure and is pivoted to the door at (6³). I
prefer to make the sector (6¹) double and unite the part on the inside of the door
with that on the outside by a bridge (66) to ensure their operating together.
sector (6) may then enter between the two parts as shewn in the figure.
The
Figure 8 shews an arrangement for combining a sector with an ordinary roller, the
sector (b) being pivoted at (62) to the door and running upon the floor of the
structure. The bar (a¹) is fixed to the door and carries a roller (h) pivoted at (h¹) to
the bar. The rail (h) is fixed to the wall of the structure and sustains the roller (h)
and its load, or the roller may be fixed in the ordinary manner as shewn by dotted
lines and run on the usual bar (c).
The sectors may be constructed in any ordinary manner and of any suitable
material and on the drawings are illustrated as made of angle iron though other
sections of iron bars may be used or wood may in many cases be used or
a combination of wood and iron. The arc of the sector will correspond in length to
the distance the door must traverse or approximately so, and in all cases the sectors
may be made double if desired similar to sector (6¹) in Figure 7 to hang the
door in a well balanced manner.
I wish it to be understood that I have not exhausted the various modifications to
which the invention lends itself; but that I have shewn the more useful forms, being
aware that a skilled person may modify the invention in many ways without
departing from the spirit and scope of the invention, as for example the arc of the.
sector may be carried upon a single arm at its bisection instead of two arms as shewn
on the drawings at its extremities.

tion and in what manner the same is to be performed, I declare that what I
