SPECIFICATION formingpart of Letters Patent No. 516,660, dated March 20, 1894.

To all whom it may concern,.-

Be it known that I, EMIL SCHRTER, asubject of the Emperor of Germany, residing at The present invention relates to a folding-l 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. y

On the accompanying drawings, Figure l 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. Fig. 2 is a plan view 'of vone side of the bed, the slides being drawn out. Fig. 3 is a section of the slides. Fig. 4. shows one of the slides in the fixed position. Fig. 5 is a plan View of the lower-side of the slides, showing the recesses f. Fig. 6 shows the slide of Fig. 4 in the released position. Figs. 7 and 8 are perspective end-views of the slides.

The slides a. a2 a4, which form the sides of the bed-frame, are arranged at the lower part A of the wardrobe in such a way that slide a4 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 0.4, these slides are provided at their lower sidei with a rack e e2 e3 through which they are alternately caught by the cog-wheel b. The latter is fixed at the one end of the shaft b 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 a2 as remain in their place because the racks e e3 have above the cogwheel b a recess f (Fig. 7), which keeps the rack out of reach of the cog-wheel. The detent-bars o o2 prevent the other slides from being dragged out at the same time by friction. The detent-bars c c2 are pivoted to each slide at h and have at one end a notch k, which catches on the plate Zin the back of the wardrobe. In this position the detentlever is fixed by placing itself against the step 1o (Figs. 3 and et). However as soon as the slide o. is entirely drawn out (Flg. 4), lever cy follows the pressure of spring d, catching with its rightend 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 notchlc releases the slide a2. Immediately afterward the nose 0 (Fig. 8) of the slide a pushes against the adjoined piece m of the slide u.2 (Fig. 7) carrying along the latter until the rack of slide a2 is caught by cog-wheel b. In turning further, slide a gets out of reach of the cog-wheel b, but cannot remain Joack toward slide a2 because the bar c of the latter forces the slide a through catching into the recess g to join in the advance of slide a2. The passing of the cogwheel b from slide` a2 to slide a3 takes place in the same way as set forth.

The folding together of the bed or of the slides is eected by turning the cog-wheel?) l in the direction opposite to that of the arrow. The slide which is nearest to the backwall thus carries along the consecutive slides by means of the adjoined pieces o m. As soon as the front slide has sufficiently approached the back wall A, the inclined plane t of the lever c, which is in the position of Fig. 6, pushes against the plate Z, and through the sliding of the lever at the hole of the plate, the lever is brought into the dotted position of Fig. 1.1.. Consequently the right-hand lever-end is lifted out of the recess g. At the same time the slide for instance a2, which is pushed forward as far as the back-wall, gets, on account of the recess f, which has 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 0.2 therefore stops and slide a. slides with the adjoined piece p over lever c. The same process repeats with the following slides except the last which has no detent-lever.

What I claim is- In a folding bed the combination of the slides a 0.2 a3 a4 provided with the racks e' e2 e5 which have recesses f and gear one after the other into the cog wheel b, the noses 0 pushing against the blocks m, the oscillating detent bars c c2 having notches lo catching over the plate Z and inclined planes and the springs d acting upon the detent bars c c substantially as and for the purpose specified.
