PROVISIONAL SPECIFICATION.
Improvements in Sliding Doors.
I, JAMES CLEMINSON of Dashwood House, 9 New Broad Street, in the City of
London, County of Middlesex, Civil Engineer do hereby declare the nature of this
invention to be as follows :-.
This invention relates to a new & improved method of mounting & operating
sliding doors.
According to one arrangement, I mount upon the door, shoes or rollers which are
arranged to work in or upon guides. :
The shoes or rollers on one side of the door are pivoted and on the opposite
side they are carried in frames fastened to the door, and in which they are free to
move in any desired direction not parallel to the guide.
I also provide a rod which is fastened to the door. This rod is formed or provided
with a crank, eccentric lever, or any other such contrivance at each end.
The cranks etc. are connected in any suitable way with the shoes, which are carried
in frames at the top & bottom of the door.
The guide is so arranged that when the door is brought opposite the aperture which
it is intended to close; one-side of the door shall be carried into the recess so that that
side shall be flush with the adjoining wall.
By turning the rod on the door, that end of the door to which it is fixed is also
carried into the recess and the whole door is then flush with the surrounding wall.
According to another arrangement the beforementioned rod may be dispensed with.
It is evident that the pivoted shoes may instead of being pivoted, be fixed rigidly
to the door a sufficient amount of play being allowed between them and the guides,
to allow the door to move on the shoes radially.
JAS. CLEMINSON.
COMPLETE SPECIFICATION.
Improvements in Sliding Doors.
1, JAMES CLEMINSON of Dashwood House, 9 New Broad Street in the City of
London and County of Middlesex, Civil Engineer, 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 new and improved method of mounting and operating
sliding doors.
According to one arrangement 1 mount upon the door shoes or rollers "A"
and "A" which are arranged to work in or upon guides "B."
The shoes or rollers "A" Fig. 5 on one side of the door are pivoted and on the
opposite side "A" Fig. 1 they are carried in frames "C" fastened to the door and
in which they are free to move in any desired direction not parallel to the guido "B."
I also provide a rod "D" Fig. 1, which is fastened to the door, this rod "D" is
formed or provided with a crank, excentric, lever, or any other contrivance at each
end as shown at "E."
The cranks etc. "E" are connected in any suitable way with the shoes "A."
The guides "B" are so arranged that when the door is brought opposite the
aperture which it is intended to close, one side of the door, (that side on which the
pivoted shoes "A¹" are fixed) shall be moved into the recess or doorway so that that
side shall be flush with the adjoining wall,

page_text: By turning the rod “D”
on the door, that end of the door to which it is fixed is
also moved into the recess or doorway, thus the whole door becomes flush with the
surrounding wall or walls.
According to another arrangement the rod "D" and cranks "E" may be dispensed
with, in this case the door will be simply pushed into the recess or doorway flush
with the adjoining wall or walls.
It is evident that the pivoted shoes "A1" may be fixed rigidly to the door, a
sufficient amount of play being allowed between them and the guides "B" to allow
the door to move in the guides radially.
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,
1st. In sliding doors the combination of sliding shoes or rollers working in or upon
guides with the cranked rod and frames or carriers as herein described and shown on
the drawings.
2nd. The general arrangement of parts together comprising my improved door as
herein described and shown on the drawings.
