catches on the plate in the back of the wardrobe. In this position the detent-
lever is fixed by placing itself against the stepp (Figs. 3 & 4). However as soon

Improvements in Folding Beds.
I, EMIL SCHRÖTER of 45, Stephanstrasse, Berlin, Germany, Joiner 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 folding-bed which is arranged in the lower
part of a wardrobe, and, which can be drawn out very quickly and in a simple
manner through the turning of a shaft.
On the drawing accompanying my Provisional Specification
Fig. 1 is a section of the lower part of the wardrobe with the bed folded
together.
Fig. 2 is a section of the wardrobe with the bed drawn out, and
Fig. 3 to 8 are single parts.
The slides a₁ a, a, which form the sides of the bed-frame, are arranged at the
lower part A of the wardrobe in such a way that slide a is fastened to the side-wall
of the wardrobe and the slide a, to the front wall of the wardrobe-under-part.
With the exception of slide a these slides are provided at their lower side with
a rack ei es e, through which they are alternately caught by the cog-wheel b. The
latter is fixed at the one end of the shaft & which takes up the whole width of the
wardrobe, and which at its other end has a second cog-wheel for working the opposite
slides. By turning the crank in the direction of the arrow (Fig. 4), the slides are
drawn out one after the other in the following manner.
First the inner slide a is drawn forth, while the other slides a, a, remain in their
place because the racks e₁ es have above the cog-wheel b a recess f (Fig. 7), which
keeps the rack out of reach of the cog-wheel. The detent-bars c c prevent the
other slides from being dragged out at the same time by friction. The detent-
bars c₁c, are pivoted to cach slide at h and have at one end a notch & which catches
on the plate in the back of the wardrobe. In this position the detent-lever is fixed
by placing itself against the step p (Figs. 3 and 4). However as soon as the slide a₁
is entirely drawn out (Fig. 4), lever c₁ follows the pressure of spring d, catching
with its right end into the recess g which, in the meantime, has passed this lever-end,
so that the left lever-end assumes the position shown in Fig. 6 and notch k releases
the slide a,. Immediately afterwards the nose o (Fig. 8) of the slide a pushes
against the adjoined piece m of the slide as (Fig. 7) carrying along the latter
until the rack of slide as is caught by cog-wheel b. In turning further, slide an gets.
out of reach of the cog-wheel b, but cannot remain back towards slide a, because the
bar €1 of the latter forces the slide a₁ through catching into the recess a to join in
the advance of slide as. The passing of the cog-wheel b from slide as to slide a,
takes place in the same way as set forth.
The folding together of the bed or of the slides is effected by turning the cog-
wheel 6 in the direction opposite to that of the arrow. The slide which is nearest
to the back-wall thus carries along the consecutive slides by means of the adjoined
pieces 0 m. As soon as the front slide has sufficiently approached the back-wall A,
the inclined plane i of the lever c, which is in the position of Fig. 6, pushes against
the plate and through the sliding of the lever at the hole of the plate, the lever is
brought into the dotted position of Fig. 4. Consequently the right-hand lever-end
is lifted out of the recess g. At the same time the slide for instance as, which is
pushed forward as far as the back-wall, gets, on account of the recess f, which has

page_text: now got over the cog-wheel b, out of reach of the rack while the rack of the next
slide a, has in the meantime caught on the cog-wheel. Slide a, therefore stops and
slide a slides with the adjoined piece over lever c₁. The same process repeats
with the following slides except the last which has no detent-lever.
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 :
In a folding bed the combination of the slides a, a, a, a, provided with the
racks ee, e, which have recesses and gear one after the other into the cog-wheel b
the noses o pushing against the blocks m the oscillating detent-bars c₁ c, having
notches catching over the plate and inclined planes and the springs d acting
upon the detent-bars c c₁ substantially as and for the purpose specified.
