COMPLETE SPECIFICATION.
Improved Chair, Convertible into a Couch or Bed.
We, WILLIAM PENN, of 3, Highbury Park Buildings, and FREDERICK PENN,
of 26, Lucerne Road, Highbury Park, both in the County of London, Cabinet
Makers, 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 :-
Our invention relates to an improved chair adapted to be extended so that it may
serve either as a combined chair and leg-rest or as a couch or bed.
In carrying out our invention we fix under the frame of the chair two frames
sliding one upon the other and adapted to be extended by telescopic screws.
These
frames when extended serve to support the cushions for forming the leg-rest or
couch. When the chair is being used as a chair the cushions are placed in a
compartment under the seat thereof.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a sectional elevation of a convertible chair constructed according to
our invention, the sliding frames being shewn in their closed up position; and,
Figure 2 is a section on the line xx, Figure 1.
Figure 3 is a view similar to Figure 1 but shewing the frames extended; and,
Figure 4 is an underside view of the same.
a indicates the ordinary framing of the chair, and b, c the extensible frames; the
former of which works upon guides 61, 6¹ on the side pieces of the frame a and the
latter on guides c', c' on the inside of the frame b. The front bar 62 of the frame b
is, as shewn in the drawings, provided with a single supporting leg d having a caster
and the front bar c² of the frame c is provided with two legs e, e having casters and
is also caused to project above the level of the frames, as shewn most clearly in
Figure 3, so that the spare cushions can be clamped between it and the front of
the chair and that when the frames are folded beneath the chair the said front bar
will form a finish to the front of the chair.
ff are the cushions which when the frame is extended are placed upon the same,
as indicated by dotted lines in Figure 3 and full lines in Figure 4, and which when
the frames are folded up are placed in the space beneath the seat of the chair, as
indicated by the dotted lines in Figures 1 and 2.
9, 9' are the telescopic screws by means of which the frames are extended, the
screw g being held against longitudinal movement in the chair-framing a and
D071

page_text: the hollow screw g' against longitudinal movement in the frame ; the thread of
the screwg engages with a thread on the interior of the screw g¹ and the thread
on the exterior of the screw y' engages with a nut on a bar c³ at the rear of the
frame c in such a manner that, when a crank-handle is applied to the end of the
screw g behind the chair, the rotation of the screw g will cause the frames b, c to
be moved out simultaneously to carry one cushion and that, when the frame b has
reached the limit of its movement, the continued rotation of the crank-handle will
cause the screw g' to rotate, whereby the frame c will be extended beyond the
frames 6 into the position shewn in Figures 3 and 4 in order to carry the second
cushion.
Although we have described our chair as being provided with two extensible
frames it is to be understood that we may in some cases use a single frame only.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A chair provided with a sliding frame or frames adapted to be extended to
support a cushion or cushions for converting the chair into a couch or bed, or
providing it with a leg-rest, substantially in the manner described.
2. The combination with a chair of extensible frames sliding one within the other
and in the framing of the chair and adapted to be extended by telescoping screws,
substantially as, and for the purpose, described.
3. The manufacture and use of the improved extensible or convertible chair
hereinbefore described and illustrated in the accompanying drawings.
