Be ,it-known that I, YVIIJ IAM' SfoHamTT a citizenozt' the' United States; and a nesident oi' thecityof' New York, borough (ifMtIii' hattan, in the county and State of New Yonk, have invented ni'new and lmp 'ox' ed G01wenti lole- @ha-ir; of which the foi'low-i ng is a, $1111, clean; and exact description."

The 1 c sii'dibiemmmem-ce the-sections lol i'gitl l enemy i elzitiveto eacifotherfthiei ribfandl groove -co11st-ruct1on' preventing any re'lntive vertical movement, and the plate and groove construction preventing any relative lateral movement. In other words, these sections can only move relatively to each other in a direction to expand or increase their total length or decrease said length. It is understood, of course, that the inner ends of the inner pair of sections are connected to one of the side frames 1 and 2, and the ends of the other pair of end sections are connected to the other side frame.

As shown in Figs. 7 and 8, it may be advisable where the expanded length of the chair is more than a certain amount to provide a cross strut, such as 13, which on its ends may be connected to the underside of a pair of the slidable sections such as 5 and j 5", as shown in Fig. 8.

The chair 1s provided with a back frame 1a which, as shown 1n Flgs. 1 and 5 particularly, is hinged to the section 3, and when the chair has been expanded to the position shown in Flg. 2 it can be folded down across the sections 3 and 3 into the position shown we in Fig. 3 to form a load engaging frame.

The chair is also provided with a load engaging frame such as 15 which isfastened in any suitable manner to the slidable sections 5 and 5, as shown in Figs. 3 and 4. The chair is also provided with a third load engaging front 16 which at its outer end is loosely connected, as shown in Fig. 4, to the side frame of the chair. This last engagement is effected by the provision of a pair of hook members such as 17 on the under end surface of the frame 16 which engages with a pair of bails such as 18 disposed on the side frame 1 of the chair. This last engagement holds the frame 16 to the side frame but permits it to be elevated.

As shown in Fig. 4, the chair has been expanded to its full length so that the frame 16 lies on top and across the slidable sections 7 and 7 and also partly across the sections 5 and 6 and 5" and 6. However, when the operation of contracting the chair takes place, the side frame 1 is forced inwardly toward the frame 2, and when this happens it will be noted that the frame 16 will ride up, as shown indotted lines in Fig. 4, on the frame 15 because the ends 19 and 20 of these frames are tapered to permit this action to take place. By reason of the fact that the other end of the frame 16 is loosely connected to permit it to be elevated as the further contraction of the chair takes place, the frame 16 will ultimately rest on top of the frame 15, as shown in Fig. 2, so that the frame 16 will directly contact with the load.

In the position of the parts shown in Fig. 2, therefore, the chair is expanded to form a sort of divan long enough to permit two or three people to sit on it. the back frame 14 is folded down across the In this case frame 3 and 3. By pulling the chair out further, to the position shown in Fig. 3, then the three load engaging frames 14, 15 and 16 each occupy a proper position across the slidable section adjacent each other to form a full-length bed. It will also be noted that the top edges of the frame 15 are provided with strips, such as 21, of any suitable material such as metal of a desired thickness, so that when the frame 16 meets the frame 15 the contact will be mainly between the edges of the frame, so that the upholstery or other fabric comprising the major portion of the surface of these frames will not bear and rub too strongly against each other, thus preventing wear.

It will thus be apparent that I have pro vided a simple, durable and compact apparatus which in its normal condition will act as an arm chair with a tiltable back which, by the usual adjusting means 22 shown in Fig. 1, can be disposed at any desired angle. It will also be apparent that this chair can be pulled out to any desired degree to form a divan or full-length bed and that the transformation of the chair into a bed can be efi'ected in a veryv simple manner and with very few operations. It is also apparent that the bed is capable ofsupport-ing the proper load without derangement even when fully extended.

What I claim is 1. A convertible chair and bed comprising a pair of side frames designed to constitute the sides of a chair in the chairforming position, of the parts and the head and foot of the bed in the bed-forming position of the parts, a plurality of front sections extending transversely between the side frames at the front, a plurality of back sections extending transversely between the side frames at the back, the front sections having interfitting means whereby the front sections are slidably inter-engaged with each other, certain of the front sections being connected with the side frames, the back sections having inter-fitting means whereb the back sections are slidably interfitted with each other, certain of the back sections being also connected to the side frames, the front sections and the back sections constituting the front and back of the chair when the parts are in chair-forming position and constituting the side rails of the bed when the parts are in bed-forming position, the front and back sections being located in the same plane and on the same level throughout their extent and being spaced at approximately the same distance throughout their extent and being symmetrically disposed with respect to the longitudinal axis of the bed to provide a bed of approximately uniform width, and load-engaging frames co-operable with the sections to complete the bed bottom in the bed-forming position and also co-operable with the sections to form the seat and back of the chair in the chair-forming position.

2. A convertible bed which comprises a pair of side frames connected by a plurality of slidably engageable sect1ons,'a load engaging frame fixed to a pair of said sections and slidable therewith, a load engaging frame loosely engageable With one of said side frames and adapted When the apparatus is in its contracted position to lie over said previously mentioned load engaging frame and adapted When the apparatus 1s expanded to form a bed to be disposed on the slidably engageable sections independently of said previously mentioned load entain of said slidably engageable sections to 20 form another load engaging frame.
