Improvements in Swivelling Sliding Doors.
I JOHN ARTHUR BRAND of Craigmillar Avenue Road Crouch End in the
County of Middlesex Architect do hereby declare the nature of this invention to be
as follows:
The door is pivoted in the centre at the top and bottom A. B. and opens on the
said pivots half the said door being inside and half outside the space enclosed by
the said door. The bottom pivot A. works in a groove C. C. the said groove being
the length of the opening of door. The bottom pivot A. consists of a wheel D
which is attached to a piece of metal E which revolves on a pin G which is fixed
to the said door. The top pivot B works in the groove H. H. also the length of
the opening of the door. The groove H. H. has a rebate I on each side leaving
the space which in the case of any but small doors is turned up at K making two
smaller grooves L on each side of large groove H. H. In the groove H. H. for
small doors runs the pivot B which is round being wide enough to let it run in
space between rebates I. I. after passing the rebates 1. I. it becomes a round
knob M which runs on the rebates I. I. and almost fills the groove H. H.
pivot B is fixed on to the door N. In the case of larger doors the pivot B. is as
follows.
The
In the grooves L. L. works the wheels 0. O. which are attached to the
metal P. P. which joins the pivot B which is similar to pivot E. and is fastened to
the door the same as G. The door opens on the pivots A. B. and then can be
pushed on the wheels either to the right or left so as to allow of entrance from the
opposite side to which it is pushed.
On each side of the door on the architrave one inside and one outside is fixed the
two beads Q to keep out any draught.

COMPLETE SPECIFICATION.
Improvements in Swivelling Sliding Doors.
I, JOHN ARTHUR BRAND of Craigmillar, Avenue Road, Crouch End, in the
County of Middlesex, Architect, 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 so construct sliding doors, that they may be
opened within a very limited space, such as may be required in yachts, or similar
small vessels. My invention is nevertheless applicable to all manner of sliding
doors, which may be necessary in buildings, and consists principally in pivotting a
sliding door in any convenient place at the top and bottom of the said door in such
a manner as it can be turned at right angles to its normal position when closed, and
that when it is turned in this position it is capable of being slid back against either
jam of the doorway on runners or wheels working within grooves both at the top
and at the bottom.
In order that my invention may be the more fully understood, I will now proceed
to describe the various figures on the seat of drawings, hereunto annexed. The
figures are marked as far as possible with like letters of reference throughout.
Fig. 1 is a part front elevation of my improved sliding door, showing the frame
around the same.
Fig. 2. is a cross section through the head when the door is a light one.

page_text: Fig. 3. is a cross section through the head of my improved sliding doors when
the said door is weighty and it is advisable to move the same upon wheels or
runners.
Fig. 4. is a cross section through the bottom of the door and frame, and
Fig. 5 is a part longitudinal section through the bottom of the door and frame,
showing the wheel or runner working along the groove.
In Fig. 1A & A respectively show the pivots or supports upon which the door
turns and is carried to either end of the frame of the doorway. Figs. 2. 34
& 5 are larger scale details of the working of these pivotted supports.
In Fig.
B is the door to which is secured the stud or pin C, having a head. C¹
and upon this head the whole can revolve within the channelled groove'C' which
is firmly secured to the frame of the door. In Fig. 3-B is the door and Ċ the
stud or pin which is now placed in such a manner as to suspend the door upon arms
which carry small friction wheels E which travel along the channel iron C. This
channel iron being as before mentioned firmly secured to the wooden framing.
An iron cap or plate is firmly screwed to the top of the door & pierced with a
circular hole to allow for the passage of the pin C-upon the head of which viz. C¹
the door revolves as before mentioned.
In Fig. 4-B is the door & F the metal casing carrying tlie friction wheel or
roller G travelling in the longitudinal groove H. Fig. 5 is a sectional' front eleva-
tion of Fig. 4 marked with like letters of reference.
When the door is closed, it will appear as in part elevation shewn in Fig. 1 and
may be secured at either end with ordinary door fastenings. When it is required
to open the door these fastenings are released & the door is turned on plan on the
pivots A and A' to the required angle, when the rollers or bearings upon which
these pivots work, can be shoved backwards against either of the ends of the door-
frame and thus the whole opening of the doorway is left exposed for use.
Although generally propose to pivot my sliding door in the centre, it is not
essential to my invention that this should be the case and in some cases it may
not be desirable.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
(1) An improved pivotted sliding door devised and constructed substantially as
herein before set forth in this Specification and illustrated by the accompanying
drawings.
(2) In pivotted sliding doors the arrangement illustrated if Figures 2 and 3
whereby the door itself may revolve upon a pin or socket in order to be puslied
back along grooves all as hereinbefore set forth.
(3) In pivotted sliding doors, the pivotting device as set forth in Figures 2 and 3
in combination with the channelled irons in head and cill of door frames for
allowing the passage of friction wheels or other bearings all as herein before-set forth
in this Specification and illustrated by the accompanying drawings.
