Improvements relating to the Pivotting of Lids, Doors, and
the like.
I, JAMES MCLAREN, of 156 Bedford Road, Bootle, Chartered Accountant, do
hereby declare the nature of this invention to be as follows:-
This invention relates to a method of pivotting lids of boxes, and doors, whereby
such lids or doors when opened may not be obstructive.
I provide the top and bottom of the door with pintles which may be of L form..
These pintles work in slots or grooves or guides in such a manner that when the
door is opened at right angles it may be pushed along said slots or guides so as to
lie against the wall adjacent to the doorway. To close the door it is pulled out-
wardly along the slots or guides and then revolved upon its pintles.
To illustrate the application of this invention to a box, I will describe a house--
maid's box. The box is divided by a horizontal division into upper and lower
stories. The upper story is open and is partitioned off for blacklead, paste, powder
and the like. The lower story forms a receptacle for brushes, cloths and the like;
and at one end has a door which is pivotted according to this invention.
Immediately under the horizontal division two horizontal slots are formed in the
sides of the box, which receive two L shaped pintles fixed in the ends of the
door. The door is thus vertical when closed, and has a horizontal axis. When
the door is revolved upon its axis until it lies horizontally, it may be pushed along:
the slots and thus lie underneath the horizontal division, ridge pieces being:
provided on the sides of the box to hold the door in such horizontal position. To..
close the door it is pulled outwardly along the slots and ridges and then revolved
downwardly.
Doors for ships cabins, hotel lifts, and other confined places, by being thus
pivotted in slots or guides which in most cases will run at right angles to the plane.
of the door when closed, may be thus opened at right angles and then be pushed
inwardly so as to lie against the wall or other surface adjacent to the doorway.
Dated this 24th day of February 1897.

page_text: Improvements relating to the Pivotting of Lids, Doors, and
the like.
I, JAMES MCLAREN, of 156 Bedford Road, Bootle, Chartered Accountant, 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 a method of pivotting lids of boxes, and doors, whereby
such lids or doors when opened may not be obstructive.
In the annexed drawings, Figures 1 and 2 illustrate my improved method of
pivotting doors or lids. Assuming the Figures to represent a lid or door the axes
or pivots of which are arranged vertically, Figure 1 is a plan and Figure is a
side view. The Figures are, however, equally illustrative of doors or lids which
rotate upon horizontally disposed pivots.
The lid or door a posseses two pintles or pivots b b, which enter grooves, c_c,
formed or provided in the walls, roof and floor, or other surface adjacent to the
door. Projecting from such surfaces are two abutment blocks, d, d.
After turning the door a through one quarter of a circle, upon its pivots, it
inay then be pushed inwardly, its pivots travelling along the grooves c. The
door then lies parallel with the surface e, which may represent either the wall
or the roof of an apartment or box. The inner end of the lid or door is then
supported by its pivots, whilst the outer end is supported by the blocks d. The
blocks d thus support the pivot side of the door when closed, and the outer side
of the door when opened.
Figure 3 shews the application of my invention to a housemaid's box. The
box is divided by a horizontal division into upper and lower stories. The upper
story is open and is partitioned off for blacklead, paste, powder and the like. The
lower story forms a receptacle for brushes, cloths, and the like, and at one end has
a door a, pivotted according to this invention. Immediately under the horizonatal
division the two grooves c are formed, in each side of the box, which receive the
pivots b fixed to the door. The door a is thus vertical when closed, and has a
horizontal axis. When the door is revolved upon its axis until it lies horizontally
it may be nushed along the grooves and thus lie underneath the horizontal
division, blocks d being provided on the sides of the box to support the door in
this position. To close the door it is pulled outwardly along the grooves and then
revolved downwardly.
+
Figure 4 shews e application of this invention to the door of a coalscuttle, the
action of which is identical with that above described in reference to Figure 3.
By thus pivotting the doors of ship's cabins, hotel lifts, cupboards, pantries,
and other confined places, in grooves which in most cases will run at right angles
to the plane of door when closed; they may be opened at right angls and then
be pushed inwardly so as to lie against the wall, roof or other surface adjacent to
the doorway. The doors thus offer no. obstruction and occupy less space than at
present. Fitted to boxes and other receptacles they may be pushed within the
box and thus do not project, and are not, liable to be wrenched from the hinges
as at present.
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:
A lid or door having nixots disposed in orooves formed in surfaces adiacent to

page_text: such lid or door, whereby the lid or door may, after partially rotating, be pushed
along said grooves; and ledges or abutments on said surfaces for supporting the
lid or door; arranged and operating substantially as described with reference to
the drawings hereto annexed.
