page_text: with the legs folded up; and Figure 30 a diagram shewing the different positions of
the stretcher. To set up the bedstead, the stretcher m, which lies beneath the side
bar, is turned about its pivot n, in the direction indicated by the arrow in Figure 30,
so as to engage the bracket 1 in the catch 2 (Figures 26 and 29) attached to the
undersido of the opposite side bar in a line with pivot n. The legs are then turned
down on their pivots (as indicated by the arrows in Figures 28 and 29) so as to
bring their ends o between the points g (Figure 4) in which position the legs abut
against the stretcher m and are then rigidly secured by means of locking bolts s¹² on
said legs, passing through holes in the ends of the stretcher and received in
staples t,, . The head piece of the bedstend is constituted by two side members u v
jointed at and to the side bars of the bedstead and braced together by a cross-
bar y similar to d. Upon the framework of the bedstend is stretched a canvas
covering attached to the frame by its edges. In order to pack up this bedstead, it is
folded by unfastening the stretchers m which are laid alongside the side bars as well as
the legs kh and the cross-bars dy. The part A is then folded on B and part C on A,
after which it is only necessary to roll up the bed in the transverse direction and to
secure it.
The above described construction may be applied to all kinds of portable bods,
whether made of wood or of angle iron. As shewn in Figure 11, the folding stretcher
is made of two parts a jointed together by struts c¹ d'. The folding stretcher is
maintained in the extended form by forcing the locking picces e' in the direction of
the arrow and turning it a quarter round from position 1 to position 2 (as shown
in the side view) whereby the two members a' 6' are held rigidly in the same plane.
Figure 12 shews a stretcher made in one piece. The two members of the stretcher
shown in Figure 13 are fitted to slide the one on the other and are retained in the
extended position by the studs a¹ abutting against the ends of the members c². In
order to dismount and collapse the stretcher, the studs a' are drawn out until their
ends 12 are in the same plane with the inner faces 34 of the part 1 thus permitting
of the latter sliding on the parts c¹ thereby diminishing the breadth of the stretcher
by about one half. Figure 14 shows a compact form of stretcher having the leg a
jointed thereto at band capable of being folded alongside the side member thereof
and of being secured in that position by turning the locking stud e¹ a quarter round
after engaging it in the slot c¹ of the leg.
Figure 16 shows a bedstead adapted to fold into a square form and specially suited
for use on ship-board for which purpose it is provided with side rails . The
arrangement shown in Figure 17 may be adapted for use as an ambulance stretcher
by inserting locking pins in the joints of the side bars and applying fixed or
removable handles at to the legs at the head and foot of the bedstead. Figure 18
shews a bedstead having straps whereby the inclination of the head piece may be
adjusted at will. To this bedstead, which is adapted to be rolled up, cross-stretchers
may be applied in the same way as to the one shewn in Figure 16.
Figure 19 shows the bedstead provided with a bed-bottom or mattress (shown
separately in Figure 20) which may be removed and applied to bedsteads of different
kinds, for which purpose it is composed of three frames jointed together. It may
also be made in two parts only and used without the bedstead, the head piece being
in that case supported at the proper inclination, as shown in Figure 25, or in one of
the ways already indicated. Figure 21 shews one of the frames of the mattress with
its mortises for the passage of the slats or laths and in which may be mounted friction
rollers (Figure 22) to facilitate the play of the sluts, which may either be of flat or
curved form, as shown in Figures 23 and 24, and made either of iron or steel or of
wood and metal. Upon the slats or laths may be stretched a covering of canvas,
leather, or other flexible material, or the longitudinal slats may be merely connected
together by cross-bands.

Improvements in Folding Bedsteads.
I, PIERRE TREMOULIÈRE, of 19 Rue de Maucaillou, of Bordeaux, France, Merchant
o hereby declare the nature of this invention and in what manner the same is to
e performed, to be particularly described and ascertained in and by the following
tatement:-
This invention relates to an improved folding bedstead capable of being packed
nto a travelling valise or of being converted into a reclining chair or a stool, as
may be required, and is specially adapted for use under all circumstances where
he reduction of weight and bulk to a minimum is desirable.
Reference is to be had to the drawings, accompanying my Provisional Specification,
vherein

page_text: side bar, is turned about its pivot n, in the direction indicated by the arrow in
Figure 30, so as to engage the bracket 1 in the catch 2 (Figures 26 and 29) attached
to the underside of the opposite side bar in a line with pivot n. The legs karo
then turned down on their pivots (as indicated by the arrows in Figures 28
and 29) so as to bring their ends o hetween the points p 9 (Figure 4) in which
position the legs abut against the stretcher m and are then rigidly securel by means
of locking bolts s¹s on said legs, passing through holes in the ends of the stretcher
and received in staples t, t, 3. The head piece of the bedstead is constituted
by two side members uv jointed at wo and to the side bars of the bedstead and
braced together by a cross-bar y similar to d. Upon the framework of the bedstead
is stretched a canvas covering attached to the frame by its edges. In order to pack
up this bedstead, it is folded by unfastening the stretchers m which are laid alongside
the side bars as well as tho legs kh and the cross-bars dy. The part A is then
folded on B and part C on A, after which it is only necessary to roll up the bed in
the transverse direction and to secure it.
The above described construction may be applied to all kinds of portablo beds,
whether made of wood or of angle iron. As shewn in Figure 11, the folding
stretcher is made of two parts a jointed together by struts cd. The folding
stretcher is maintained in the extended form by forcing the locking pieces el in
the direction of the arrow f' and turning it a quarter round from position 1 to
position 2 (as shown in the side view) whereby the two members a 6' are held
rigidly in the same plane.
Figure 12 shews a stretcher made in one piece. The two members of the stretcher
shown in Figure 13 are fitted to slide the one on the other and are retained in the
extended position by the studs a' abutting against the ends d' of the members c¹. In
order to dismount and collapse the stretcher, the studs a' are drawn out until their
ends 1, 2 are in the same plane with the inner faces 3, 4 of the part 6', thus per-
mitting of the latter sliding on the part o', thereby diminishing the breadth of the
stretcher by about one half. Figure 14 shews a compact form of stretcher having the
leg a jointed thereto at ¹ and capable of being folded alongside the side member
thereof and of being secured in that position by turning the locking stud e³ a quarter
round after engaging it in the slot e' of the log.
Figure 16 shews a bedstead adapted to fold into a square form and specially suited
for use on ship-board, for which purpose it is provided with side rails . The
arrangement shewn in Figure 17 may be adapted for use as an ambulance stretcher
by inserting locking pins in the joints of the side bars and applying fixed or
removable handles at ¹¹ to the legs at the head and foot of the boilstead. Figure 18
shews a bedstead having straps k¹ whereby the inclination of the head piece may be
adjusted at will. To this bedstead, which is adapted to be rolled up, cross-stretchers
may be applied in the same way as to the one shewn in Figuro 16.
Figure 19 shews the bedstead provided with a bed-bottom or mattress (shewn
separately in Figure 20) which may be removed and applied to bedsteads of different
kinds, for which purpose it is composed of three frames jointed together. It may
also be made in two parts only and used without the bedstead, the head piece being
in that case supported at the proper inclination, as shewn in Figure 25, or in one
of the ways already indicated. Figure 21 shews one of the frames of the mattress
with its mortises for the passage of the slats or laths, and in which may be mounted
friction rollers (Figure 22) to facilitate the play of the slats, which may either be of
flat or curved form, as shewn in Figures 23 and 24, and made either of iron or steel
or of wood and metal. Upon the slats or laths may be stretched a covering of
canvas, leather, or other flexible material, or the longitudinal slats may be merely
connected together by cross-bands.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is;
The herein described construction of folding bedstead formed of members so

page_text: jointed together that it may either be rolled up or folded into a small space and
may either be converted into a reclining chair, stool, or ambulance bed, sub-
stantially as specified.
