SPECIFICATION forming part of Letters Patent No. 491,080, dated February 7, 1893.

Application filed December 3, 1890A. Serial No. 373,906. (Nor model.)

To all whom it may concern.-

Beit known that LALBERTFORBES CONANT, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Convertible Beds, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claims.

Io In Said drawings-Figure 1, is a front elevation showing my invention as with the convertible bed arranged for use as a lounge. Fig. 2, is a vertical transverse section through Fig. 1; and with the parts as there arranged.

I 5 Fig. 3, is a section similar to Fig. 2, but with the bed as arranged for use as Such. Fig. 4, is a view similar to Fig. 1, but with the valance 7, and removable cover 9,0mitted. Fig. 5, is a detached sectional elevation as on line W, Fig. 3, viewed as from the right therein.

Fig. 6, is a detached vertical section taken as on line X, Fig. 5, and viewed as from the left therein. Fig. 7, is a detached perspective view Showing the hinge and part of the back,

in enlarged scale.

The obj ect of my invention is to provide, at low cost, and with simplicity of construction, a bed that may be quickly converted into either a lounge or bed as desired, and which 3o may be made up in the morning and then used during the day without disarranging the bed-clothes. And it consists in certain features of novelty and the combinations thereof,as will be hereinafter fully described and 3 5 clearly claimed.

Referring again to the drawings; A, represents a book case or cabinet, which may be made with any desired degree of ornamentation, and which possesses the essential fea- 4o tures of ends ct, a., united by a back b; the

shelf-like top c, the book supporting shelf d, secured in ends a, below c; to which may be added an ornamental metal rail f, supported in short standards g, g, secured to top c, and

serving as a guard for the articles of ornament 5o holstery is shown at m, and as resting upon springs Z, which latter may or not be' employed as preferred. This bed is made of suitably upholstered as at t, and of a width to extend from shelf d, down to and somewhat into upholstery m, to slightly compress the same, is secured in place by the link like hinges u, one end of which is pivoted to plate '0, secured upon the back q, by clamp 2,-while the opposite end is pivoted to plate w, that is secured to bar that slides upon bar y, secured beneath the shelf d. One of the bars y, is thus secured near each end of the bookcase, while bar @@extends the lengthl thereof, and a hinge is Secured to said bar @and back q, near each end, as is shown at one end in Fig. 5, and as shown by dotted lines in Fig. 4.

The pivot plates o, to which hinges ware pivoted, slide freely in clamps 2, and to their lower ends is secured a helical spring 4,which vof at its lower end is attached to stud 5, secured A in the back.

At the ends of the book-case I arrange the head and foot boards e, pivoted at n, to ends a, and having a supporting stud z, that passes through the curved slot 6, whereof n, is the radius point. When the bed is used as such,

back q, is arranged at the back of the bookcase, as in Fig. 3, and thehead and foot boards are turned down as there shown. ranged as a sofa or lounge, the boards e, are turned up within the book-case, as shown in Fig. 2, and back q, is brought forward and po- When ar- .v

sitioned as there shown, its lower edge resting upon cushion m, while it is supported in rear by studs 3, of the head and foot boards, projections 8, on the back catching beneath the upper studs 3, and thereby holding the back in place. To allow back q, to pass between Studs 3, when in the position shown in Fig. 3, the back is forced downward, thereby extending spring 4, when the upper edge of the back is moved to the front, thereby moving the sliding bar forward, when the back may be moved outward between studs 3, as indicated by dotted lines in Fig. 2, after which itis positioned as indicated in said figure. To return the back to the rear of the book-case, the reverse movement occurs, the

Spring yielding to pressure allowing the back but sustaining the back, when the downward pressure occurs, in the position shown in Fig. 3, and always aiding in holding the back suspended, forits easy manipulation as specified.

As the bed remains always level, it may with the exception of the pillow be made in the morninofread 'for the next niffhts occu )anc D y D 9 as the use as a lounge does not disturb the bed clothes. And further it may, in a few moments, by merely moving the back uponits pivotal and sliding supports, be without dif-- culty or material labor changed to either conl dition as desired.

A removable cover shown at 9, and corresponding in material with covering t, of theback, is provided to be placed upon the bed during the day, and is removed at night when the bed .is to be occupied as such.

It will be obvious that various changes in details may be made without departing from the essential nature of my invention, which consists in a bed provided with an adjustable back, which can be moved out of the waywh en the bed is usedas such, and when used as a sofa or lounge, the back is adjusted tovserve not only as a back, but to partition off and requisite space between its ends a, d and below shelf d, bed B formed to be in part arranged in the space in the cabinet as shown; the sliding bar arranged beneath said shelf and thereto secured with adaptation for a forward and back sliding motion, and adjustable back q, pivotally attached to said bar, substantially as specified.

2. The combination with back q of bar ac arranged beneath shelf d to slide forward and back, hinge u secured to back q, the pivot plates o, connected with hinge u and secured to back q, the guiding clamp 2 and spring 4E attached to the plate and back, substantially as specified.

3. The combinationswith cabinetB, and the bed, of the head and Vfoot boards, pivotally attached to the :ends of the cabinet and arranged to beturned Vup and down, substantially as specified.

4. The-combination with cabinet A,ot' bar x, arranged therein to slide from fronttorear; the adjustable back q, and the hinges capivotally attached to said bar and back, substantially as specified.

5. In a convertible bed, the combination of the inclosing case, thc-foldinghead and foot boardsprovided with the studs 3, and the back hinged to the case and provided with projections 8, arranged to en gage-beneath/said4 studs when the back is therebyfsupported, substantially as specified.
