To all-whom 'it may concern:

Be it known that I, JOHN E. CHATEM, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and.

useful Improvements in Wall-Beds, of which the following is a specification.

It is the objects of this invention to provide a wall-bed or the like, which can be raised and lowered with erfect ease and Without any danger or liabi ity of accidental folding up of the bed, and in which the force exerted for raising and lowering the same will be approx'imatel equal to that required for sustaining the ed throughout the entire movement in' either direction; to provide an improved bed-frame adapted to a Wall-bed, the same being superior in the matters of strength, rigidity, and lightness combined, so that the force necessary to manipulate the bed may be brought to a minimum; to provide for using such frame either as a wall bed or as a chamber bed to be moved about the room.

- The invention may be carried out in various forms, and l shall illustrate the saine in some of the forms in which l contemplate embodying the invention.

The accompanying drawings illustrate the lnvention.

Figure 1 is a fragmental perspective view of a Wall bed embodying my invention, with tension devices of various kinds applied to the same bed-frame. lt is to be understood that in ordinary practice, only one kind of tension device would usually be employed in any one bed, although all three devices might be-ein loyed if so desired. Fig. 2 is a fragmenta plan of the bed shown in Fig. 1. Fig. 3 is a fragmental detail of the bed with the post extensions in place to fit the frame for use for a portable bed. Fig. 4 is a fragmental detail showing the spring tension devices supported against the face of the wall.

Fi 5 is a fragmental, vertical, sectional de` tai showing the bed in lowered position withl the weight tension devices in use, together with s rihg tension devices. Fig. 6 is a fragmenta elevation from line Fig. 5, lookin left. Fi 7 is a fragmental detail of the coil tension evice. Fig. 8 is a fragmental detail of the facing and base, and the hinge which connects the same. Fig. 9 is a detail of one form of clip 6. i

1 designates a recessed Wall or other body in which the bed is to fold.

2 is a bed-frame.

3 is a facing hinged by hinge 4 to the base 5 of the wall or body 1 to close the wall recess.

The bed frame is preferablyconstructed of light steel bicycle tubing and ttings, for the purpose of combining great ri `dity and eX- treme lightness. The saine be described more in detail hereinafter. 6 designates clips by which said frame is'removably attached lto the facing 3, so that the facing and the frame may rise and lower together as the facing ismoved on its pivot 4.

7 is a standard or foot which projects from the facing 3 and serves to su port the free end of the framewhen the bed) is in lowered or horizontal position.

Cumulative tension devices are connected with an upright 8 at a point above the pivot 4, and are adapted to exert their force cumulatively to sustain the-bed against the force of gravity, as the saine is lowered to horizontal position, and to successively cease to exert lifting force onthe frame as the same rises to upright position. The tension means for exerting such force may be of different kinds.

In the drawings, springs 9, 10 and 11 take the weight successively in the order named as the bed-frame is lowered, and s rin 9 receives the strain of the lowering ed efore any such strain comes upon connection 13 which applies tension to spring 10, after which connection 14 acts on s ring 11.

In the drawings two sets o like springs are shown. In each set the three springs are connected with a single cross-head 12. rThe spring 9 being longest, is connected directly to said cross-head; the Spring 10 is connected by connection 13, which is of such length as to leave .a slack line, as indicated in Fig. 4,v

after the strain has been vapplied to spring 9 and spring V11 is connected with a cross-head by connection 14 having more slack than connection 13.

15 is a connection led under a (pulley 16 and yconnecting the cross-head 12 with the bed-frame above the ivot 4 thereof. Said connection 15 may a so be connected with the connections 17 which pass over pulleys 18 and are connected with cumulative Weights as 19, 20, 21 and 22.

Connections 17 may be in pairs, as shown in Fi 6, one of said connections being fastene to a weight 19 which in turn is fastened by connections 23 with another Weight 21, while the other connection 17 which iscon- 4be rst to take up nected with connection 15, may be connected with a weight 20 which in turn is connected by connectionsi 24 with weight 22. Connections 17 and 17 lare of such length that when ythe bed-frame is brought to upright position in the recessedbody 1, the weights 20, 21 and 22 will all be at rest, the gravity of weight 19 being sulicient to. hold the bed in its upright position; or in case Weights and springs are used, the combined force of the springs 9 and the weight 19 may' be used to serve the bed in place.

When the frame is lowered the 'effect will the slack of connection 17 until weight 20 1s lifted. At the same time the slack of connections 23 will be taken up so thatafter the weight 20 has been lifted the weight 21 will be acted upon to raise it from its support, as the floor 25. Further downward movement ol" the bed will take up the slack of the connections 24 until the Weight 22 is lifted from its support, as the floor 25.

Itis evident that the same movement may operate successively upon the springs 9, 10 and 11 the connections of which may be appropriately arranged to bring them successive y into action. On return movement of the bed the weights and springs Will come to rest in reverse order.

The tension device ma be in the' form of coil springs, as detailed 1n Fig. 7, in Which purpose of holding the spring 26 will be brought into action first ony lowering the bed, an spring 27 is of such 'tension asy to come into action later; said springs acting cumulatively after the same l manner as that described forthe weights and springs 9, 10 and 11.

In case it is desired to use the bed apart from the wall and the facing 3, the clips 6 may be loosened and the bed-frame 2 removed from the facing which may then be raised to close the openingv 28 in the wall, which o ening is normally closed by doors 29 held y springs 30 when the bed is down, the cords 31 serving to draw the doors rearwardly as the bed moves upward. When the frame 2 has been released, the post extensions 32 may be inserted into the sockets 33 in the bed-frame, whereupon said trame becomes an ordinary portable bedstead deyieidin tions 45, which pipe sections extend upwardly from the corner tees 40.

46 designates fittings at the tops of the niples or pi e sections 45, and'v47, 48, designate vbars held yttings 44 and 46 to form with the bars 43 the head and foot frames of the bedstead.

49 and 50 designate intermediate crossbars and rails connected b tees 51 With the side rails of the bed, and y braces 52 with the end bars 47 to which the bed-springs 53 for the mattress will be attached. Braces 54 are provided extending from cross bars y49 at the wall end of the bed to the top rail 48 at'such end.

55 represents uprights at saidwall end of the bed to support the top rail 48.

All of the parts of the frame are constructi ed of light steeltubing, and appropriate fittings therefor, and by this construction a su erior rigid frame is produced.

he braces 52 and 54 that are connected with the uprights and side-rails of the bed, are set aslant, as shown, to take the strain oi the tension devices and of the power a plied for pulling the frame down, and also t e ward the tension will diminish, and vice versa. 1n the act of lowering the bed, the strain of the tension devices on the upright 8 increases, and such strain continues to be exerted until the bed is again brought to upright position. Provision is made for resistino' the strain'b oonstructingthe frame of ligbht steel bicyc e-tubing with the braces 52 and 54.

It is to be understood that in practice, 0' means of determined strength will be employed to sustain the bed including the frame, the mattress, the bed clothing, and all the ap urtenances that are to be yraised with the be -frame for storing the same in the recess; and that the strength or power of the successive elements of the cumulative yielding bed-sustaining means will be normally such at each stage of movement as may be re uired at such stage to cause th process ofclowering or raising the bed to require only minimum manual power. By hinging the bed frame to the base board -5 which extends across in front at the lower end of the recess the bed is rigidly held in place in both the upright and the lowered position and the mounting is thus constructed at a minimum cost.
