BED-BOTTOM.

SPECIFICATION forming part oi Letters Patent No. 378,397. dated February 21, 1888,

Application filed February 24, 1855. Serial No. 156.716. (No model.)

links in position and in combination with parallel slats. Fig. 2 is a sectional edge view. Fig. 3 represents a bottom view of my improved bed with the slats closed; Fig. 4, section of cross-jointed slat-connection; Fig. 5,

lllOdlfiCiitlOll of Fig. 4, showing the links con nected separately to the sliding clip; Fig. 6, a modification in manner of attaching links to the slats.

My invention relates to that class of bedbottonis provided with slats and coiled springs adapted for lateral adjustment; and it consists in the combination and arrangement, with a series of slats and coiled springs, of aseries of double cross-jointed links and slides embracing the slats, and also of a combination, with a series of lower or supporting slats, of an upper or elevated side slat located upon each side of the said bed, sustained by an angular or bent arm connecting the upper and lower outer slats, as will be hereinafter more fully described.

The object of the first part of my invention is to insure a uniform parallel movement of the lower slats in unison when adjusted for 7 different widths of bed-frames by contrivances that leave the upper surface of the lower slats nearly bare, and therefore less liable to afford a hiding-place for vermin than those provided with joints above, and also to prevent undue endwise movement of the slats beyond the others by means of the peculiar link-connection solely.

The object of the second part of my invention is to insure possibility of the folding or closing of all the slats tightly and uniformly together side by side in packing without requiring other means than the cross-jointed links specified to insure the object specified.

In the drawings, A represents the slats arranged parallel in their relation to each other;

B, slats elevated above the others, A, at each side of the bottom, which not only serve to connect the row of springs thereunder,but also to prevent their tilting when such slats are connected with the lower ones by the angle of flexible brace, hereinafter specified.

D are flexible arms or connections, (more clearly shown in Fig. 2 of the drawings,) composed in the particular instance of a suitable strip of narrow springy metal bent at an angle, one end of which is secured to the top slat, B, and the other to the slat or slats A below.

E are links of metal jointed together substantially at three points, or as shown in Figs. 1 and 8 in the drawings, the object of this double-jointed arrangement of links being to connect the slats A in such manner as to prevent undue end motion of the said lower slats and at the same time insure a more firm support for the entire structure.

It will be observed that Fig. 1 of the draw ings shows the links E pivoted or jointed to the slats A at or near the extreme end of the latter. This is preferable, yet not essential, as will appear obvious to those skilled in the art, as the links E may be hinged to the slats A at the opposite point and the slide clip F operate between the end of the slat and the rivet or hinged point of connection, as shown in Fig. 6, representing such modification.

Fig. 4 represents the ends of two linksovering through them and the back of the clip by which they are hinged together, while Fig. 5 represents a connection of the same parts by two rivets or bolts without the overlap of the links, as in Fig. 4.

The slide is so formed as to clasp around or embrace the edges of the slats A, to which they are attached and upon which they are adapted to slide when operated, all of which will be readily understood by one skilled in the art to which the invention pertains. The parallel slats may be made of any suitable material, although I prefer, however, thin metal as being the most proper, owing to the peculiarity of the construction of the other parts. In this instance the cross-jointed links are represented as united by rivets, although it is obvious that screws, clips, or other means may be employed for uniting the parts. The

lapping each other, with a bolt or rivet passcoiled springs are of the kind and character Well known for such purposes, and are so: cured to the lower slats, A, in this instance by rivet. The upper part, excepting the row immediately under the top slats, B, is left free. The angle-brace, which is rigidly riveted to the outer, upper, and lower' rails, serves to properly support and retain the outer in position and prevent undue tilting, and by means of which the center rows of slats are maintained in their respective proper position. The cross-jointed links, which are riveted pivotally to the ends of the lower slats, as shown, prevent independent end movement of the slats, and the several parts are held as an entirety more firmly than when a connec tion of single connected links' is employed, and all undue lateral strain to the coiled springs is prevented by the suspended anglearm and slat, and the central springs are allowed to act freely and without the necessity of connecting them together at their tops, except as previously stated.

I do not wish to be understood as claiming, broadly, a bed-bottom or springmattress formed of slats, springs, and a support for an upper side rail or slat, as Iain aware that slats located parallel with each other supporting coiled springs are not new. I am also aware that with the combination of slats and coiled springs links for uniting said slats have been used for the most part single and not crossjointed nor secured to the slats, as shown in the drawings forming a part of myprcscnt application. Neither do I claim an arm or support, broadly, for sustaining side rails or slats above the base-slats, as I am aware that an arm of a similar character has been previously shown. My device differs materially from this in that the arm or supportin myinvention is, so to speak, of flat metal and in form halfelliptic, one end of which is firmly secured to the outer lower base-rail and the other to the upper side rail in a manner permitting the slats to close closely together side by side, and also to prevent the upper or side slat from undue end movement.

Having thus set forth my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, is-

1. In aspring bed-bottom, the combination, with a series of slats united together by double cross-jointed links, one end thereof attached to or near the end of said slats and the other to sliding devices or clips embracing said slats, adapted for simultaneous adjustment, and each held and supported in parallel relation to each other, of the two outer slats secured together, one of which is supported above the other by means of a bent springy arm of metal, in addition to the coiled springs, substantially as and for the purpose set forth.

2. A spring bed-bottom consisting of a series of parallel slats forming abase-support, the combined width of which is adapted for simultaneous expansion and contraction by means of double cross-jointed links and slid ing clips united together, said links extending across, connecting with, and sustaining each slat in a fixed parallel and endwise relation to each other, a series of coiled springs, and two elevated side slats connecting with and sup ported above the outer slats of the former, all arranged to operate as described.

3. 1n aspring bed-bottom, the combination, with a series of parallel base-slats united at or near their ends by double crossjointed Iconnecting-links, sliding clips, and coiled springs,

of one or more angular springs rigidly secured to and connecting the outer base-slats and the said elevated side slats, substantially as and for the purpose set forth.

4. In a spring bed-bottom, the combination of a series of parallel base-slats, each connected, supported, and adapted for lateral adjustment by means of double-jointed crosslinks, one end of which is pivotally connected to said slats and the other to sliding clips, coiled springs, elevated side slats, and flat angularly-arranged springs D, connecting and supporting the latter, as described.
