Improvements in Convertible Furniture.
1, LORENZ WOLZ, of 94, Hauptstrasse, Röllbach, Germany, Innkeeper, 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 present invention relates to a frame which owing to its special construction
and to the combination of its different parts, can be employed as a chair, stretcher,
operating table etc. etc.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters
and figures marked thereon.
Figs. 1, and 2, represent the frame arranged as a stretcher or litter.
Figs. 3, and 4, show the same frame so arranged as to be capable of serving
as a chair with its back.
Figs. 5, and 6, represent the frame so folded up as to be capable of being used
as an operating table.
Figs. 7, and 8, show it arranged as a sofa or couch.
Fig. 9, shows the frame folded up.
The frame is formed of two bars A located in the same plane and arranged
parallel, these bars being connected between themselves by two transverse or
cross pieces and two stirrup shaped pieces . The bars A consist of four
parts a, c, d, f, connected together and held by hinges e, in such a manner as to
be capable of being placed in accordance with the employment or use that it is
desired to make of the frame. The parts f and d carry the stirrup shaped pieces i
which are mounted thereon upon pivots h upon which they are capable of
turning and the lateral sides of these stirrup shaped pieces are provided with
studs, heads or projections riveted upon the said stirrups shaped pieces, and by
means of which these latter may be secured in any desired position by introducing
the said heads or projections in one of the holes formed in the supports which
latter are so mounted as to be free to rotate upon the parts a and c; the same
object being also attained by the metallic bands m which are free to rotate at .
upon the parts d and f. The surface (sail canvas, etc.), which is intended to
receive the body to be transported will be secured to the stirrup shaped pieces i.
The parts a and c are provided at convenient points with hinged or jointed sup-
ports o, which in case of necessity would be capable of serving as feet when the
frame has been so arranged as to form a stretcher or litter. Moreover, the
exterior parts a and c are jointed to the central part f and d in such a manner
that they can be arranged two by two, as is shown in the arrangements represented
in Figs. 3, 4, 5, 7, and S. The parts a, c, act as feet or legs in the latter
arrangements, and are provided, for that purpose, with openings or apertures v
formed at certain intervals apart through which a rod cr pin can be passed to
increase the strength and rigidity of the base.
In the case of the application of the frame to form a stretcher or litter as shown

page_text: in Figs. 1, and 2, the parts a, f, d, and c, each form separately a straight bar
which is connected by means of the cross pieces or transverse pieces 6 which are of
the same length, and by the stirrup shaped pieces i, to the other bar which is
placed parallel to the first, and which is situated in the same plane as this latter.
The stirrup shaped pieces are held by the pivots h upon the parts f and d and serve
to form a support for the head of the invalid who is placed upon the stretcher
or litter. The supports admit of the stirrup shaped pieces being adjusted into
any position that may be found suitable for the condition of the invalid. The
hinged supports serve in this case as feet. The other applications of the frame
are illustrated in Figs. 3, to 8, which will be easily understood without further
explanation.
This frame could be very advantageously employed, in case of war, as a litter
or stretcher, operating table, arm chair etc., as also as a couch or sofa, chair etc.,
etc. in any family.
!
By moving the feet or legs out to a greater or lesser extent (or such parts or
members of the frame which perform the office of feet or legs) in the different
arrangements hereinabove mentioned, all the positions suitable to resting the
body can be given to them.
Having now paricularly 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 frame characterized by two bars A parallel and situated in the same plane,
bars each of which is composed of four parts a, c, d, f, connected together by
hinges e, the said bars being connected together by means of transverse or cross
pieces and stirrup shaped pieces which are attached to the central parts f
and d by means of pivots the whole with the object of being able to utilize
the said frame, by altering the relative position of its different parts, as a stretcher
or litter, chair, table, etc., etc., substantially as hereinabove described and illus-
trated in the annexed drawing.
