Specification of Letters Patent.

Patented Feb. 10,1920.

Application filed. July 26, 1919. Serial No. 313,630.

To all whom it may concern:

Be it known that 1, PAUL SKWARKO, a citizen of Ukrania, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Collapsible Beds, of which the following is a specification.

This invention relates to collapsible beds, and has for its principal object the provision of a bed which may be collapsed laterally so as to be used. either as a single or a double bed, the operation of changing from the former to the latter, and vice versa, being easily performed, in either case a comfort able bed being provided.

The above and other objects will lie attained by the novel construction and combi nation of parts below described, and as illustrated in the accompanying drawings, in which characters of reference refer to likenamed parts in the description.

Referring briefly to the drawings, Figure 1 is a top plan view showing a bed made in accordance with the invention, the same being in a partly collapsed or folded position.

Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a perspective view showing in detail the engaging mattress features.

Fig. 4 is an enlarged fragmentary transverse sectional view taken on the line H of Fig. 1.

Referring now in detail to the drawings, the numerals 10 and 11 represent the side posts of one section of the bed frame, and 12 and 13 the side posts used in supporting the inner or collapsing element, the posts 10 and 11 being connected by suitable crossrails 14 having interiorly overhanging elements in which are recesses 15, receptive of tenon-like rails 16 connecting the inner eX- tension frame section at the .top of the posts. Similar laterally extending, longitudinally disposed tenons 17 enter into corresponding grooves 18 near the lower portion of the ends of the main bed frame.

A side rail 19 is engaged between the rear posts 10 so as to hold the main frame structure in proper rigid position. The posts are connected by a pair of rails 20 on the open extensible side of the bed, upon which rails rests the lower plate 21 of a U-shaped metallic frame having a parallel plate 22 which is engaged with the lower plate 21 by a vertical plate 23 forming a rectangular structure open on its inner side, these elements being held apart by rails 2st so as to form a substantial, rectangular structure.

A plurality of openings 25 are formed in spaced relation through the plate 22 in which are secured rings 26, the latter engaging hook elements 27 which support the mattresses 28 and 29 the lower mattress 29 having connecting elements 30 engaged in rings 31. The latter are secured in openings 32 formed in plates 33 having diagonal inner edges and being formed with vertical elements 3% extending up from plates 35 slidable on plates 21 laterally of the structure so that the mattresses may be disposed one Over the other, as is best illustrated in Fig. 2.

In order to prevent complete separation of the major and minor bed frame elements, openings 36 are sheared in the upper plates 22, the material being turned down to form projections 87 adapted to make contact with upturned lugs 38. Said lugs are formed on the ends of joint plates 39 which are bent at right angles to extend under the plates 35, and formed with upturned sides 40 looped around upstanding elements 41. The latter are formed with plates 35 and held in position by the inwardly turned ends 42 0f the plate sides 40, thus permitting lateral extension of the bed elements in an obvious manner, but preventing their complete separation.

It is thus apparent that the frames may be separated or moved together without confliction of the engaging parts.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:

In combination with a four-posted structure having relatively wide ralls extending between upper ends of the foot and head posts, and walls therebetween, a second fourposted structure, tenons formed with said second structure adapted to enter longitudinal grooves formed in the rails and walls of the first-named structure, a mattress attached to each of said structures, one above the other, and means adapted to guide the relative sliding motion between said structures comprising a frame of the shape of a U lying on its side attached to one of said structures, a substantially S shaped frame attached to the other of said structures and having one of the tongues of the S slidably engaging one of the legs of the U between the legs thereof, and means for preventing the complete disengagement of said strucsuffieiently far separated, so as to prevent tures relative to each other comprising a further relative motion. vertical tongue out out of the upper leg of Signed at Pittsburgh in the county of Al 10 the U shaped frame, and a vertical lip exlegheny and State of Pennsylvania this 12th 5 tending from the end of the S shaped frame, day of July A. D. 1919.

the last-named tongue and said lip adapted to mutually engage when the structures are PAUL SKl/VARKO.
