SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 544,616, dated August 13, 1895.

7 Application filed December 6, 1894. Serial No. 530,987- (No model.)

To aZZ whom it may concern.-

Be it known that 1, PETER FRASER, of East Whitman, in the county of Plymouth, State of Massachusetts, have invented certain new and useful Improvements in Spring Bed-Bottoms; and I do hereby declare the following to be a full, clear, and, exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention relates to improvements in spring bed-bottoms, and is designed particularly to supply the need for a spring bed-bottom which will be capable of use in an ordinary iron bedstead having narrow side rails without raising the level of the bed above the normal elevation.

A further object of the invention is to provide a metallic structure which will not harbor vermin and which shall be capable of adjustment to fit beds of difierent size.

The invention consists in certain novel details of construction and combinations and arrangements of parts, all as will be now described, and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure 1 is a top plan view of a bed-bottom constructed in accordance with my present invention. Fig. 2 is a perspective view of one of the hangers. Fig. 3 is a detail of one end of one of the cross-pieces. cross-section on the line 4 4, Fig. 3. Fig. 5 is a similar section showing a modification.

Like letters of referencein the several figures indicate the same parts.

In carrying this invention into practice, cross-pieces or foundation-pieces A are provided, of angle-iron, to the upper sides of which the usual thin supporting-strips B, upon which the springs C are mounted, are

connected. The strips B and springs C are of usual construction and need not be further described, save that sufficient of both are pro: vided to form a bed-bottom of the proper size. The cross-pieces or slats proper of the bed bottom, before referred to as being made of angle-iron, are preferably sufficient in number to provide one slat or cross-piece beneath each transverse row of springs. Thus, the

Fig. 4. is asame fastening may be employed for uniting the springs and the longitudinal and transverse slatssuch, for instance, as a rivet or equivalent D. The slats proper or cross-pieces A are of such length as to pass readily within the narrowest bed in connection with which the spring is designed for use, and in the angle at each end of said cross-pieces or slats I form guides or sockets, as shown in Figs. 3 and 4, for instance, where the extreme end of the angle-iron is bent into a circular socket or sleeve E, and, at an intermediate, point slightly removed from the end, ears struck out of the angle-iron are bent into a second tubu lar socket or sleeve E. These sleeves or F guides, as they may be termed, are adapted for the reception of the horizontally-project ing ends F of the hooks or hangers, which take over the side rails of the bedstead. The

hooks or hangers are preferably formed from lengths of heavy Wire or rod metal with the ends F straightened out in horizontal position to enter the guides, as just mentioned, and the intermediate portion bent first into a double hook-like structure f at the top, the ends being carried thence downward at f and toward each other, where the approximate portions are unitedby a clip H, thence outward again and at right angles to form the portions F. The horizontal portions F are such dis. tances apart as to enter the ends of adjacent cross-pieces or slats, and, in effect, it may be said that the slats are arranged in pairs, which, together with the two hangers, one at each end, constitute what might be termed a foundation-piece for supporting the spring proper, although, as before stated, the longitudinal slats B are relied upon to unite the whole to form an integral structure.

The hangers are adjustable in the guides, from which it follows that the spring may be applied and will fit with equal facility beds of somewhat varying width.

In lieu of forming the guides or sleeves directly from the metal of the angle-iron crosspieces, I may form said guides or sleeves from an independent piece of sheet metal, as shown, for instance, in Fig. 5, wherein a tubular sleeve H is formed in the independent piece of sheet metal, and the ends it of said piece are extended out parallel with the inner sides of the angle-iron and united therewith by rivets or equivalent fastenings 7b. This structure has some advantages, in that it does not weaken the angle'irons or cross-pieces, but, on the contrary, provides a strengtheningtube, one at each end, which will assist in resisting the tendency to bend when Weight is placed upon the cross-pieces.

Having thus described my invention, what I claim as new is-- 1. The combination with the longitudinal slats carrying the springs, of the transverse slats connected with the longitudinal slats at their points of crossing to form an integral structure, and the upwardly extending hooks or hangers adapted to take over the side rails of the bedstead and having the horizontal portions united to the transverse slats by a sliding connection; substantially as described.

2. A bottom for beds consisting of a series of slats or cross pieces and a series of hangers consisting of upwardly extending hooks adapted to take over the side rails of a bedstead, each of said hooks or hangers having two horizontal portions connected respect ively with adjacent slats by sliding connections; substantially as described.

A foundation cross piece or slat for spring bed bottoms composed of strips of angle iron having the tubular sleeve guides at each end in the angles thereof and hangers having the parallel horizontal portions for entering the guides in adjacent slats, the uprightproximate-portions united by a metal clip and the hook portions adapted to take over the side rails of a bedstead; substantially as described.

4. Afoundation cross piece or slat for spring bed bottoms composed of an angle iron having the tubular guides or sleeves at each end formed by bending portions or ears of the angle iron inward and the upwardly extending hooks or hangers having the horizontal straight portion adapted to enter the guides or sleeves and the upwardly extending hooks adapted to take over the side rails of a bedstead; substantially as described.
