To all whom t may concern:

Be it known that I, EUGENE FULLER, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented Acertain new and useful Improvements in Bed- Bottoms, of which the following-is a speciiication.

My invention relates to bed bottoms or mattress frames and has for its essential objects a uniformY tension throughout the fabric; the facility of interaction of constituent units or -parts'of the fabric; adaptability to independent movement of various areas; flexibility and strength; inexpensiveness of construction; adaptability for assemblage and disassemblage; and absence from the exposed fabric surface of irregularities tending to tear or abrade clothing, cleaning cloths, or other material. To the above ends essentially my invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims. Y

In the accompanying drawings which form a part of this specification F igure 1 is a top plan view of mattress frame or bed bottom embodying my invention,

Figs. 2 and 3, side and end elevations respectively of the same,

Fig. 4, an enlarged bottom plan view of one of the fabric units showing portions of the connecting rods broken away,

Fig. 5, a section on line 5-5 of Fig. 4, and

Figs. 6 and 7, bottom plan views of the marginal and corner fabric units respectively.

Like reference characters indicate like parts throughout the views.

The mattress or stretcher frame in the present instance comprises end bars 10 including flanges 11 and connected by side rails 12. The bed bottom or fabric comprises longitudinally disposed rods 15 ar ranged in rows. As illustrated, these rows comprise marginal or lateral rows 17, and intermediate rows 18. The number of rows is optional. The ends of the rods have enlarged portions or heads 20, preferably of curved contour, and vin this instance spherical in shape. Similar rods 22, having like heads 23, are arranged in rows transversely of the frame and fabric, and comprise marginal or end rows 25, and intermediate rows 26.

At the points of intersection of the intermediate rows are connecting units or members represented in a general way by 28. In detail each unit comprises a flattened hollow body 29 andi-four radial tubu' lar arms 30 with retracted ends 31. The top wall'of each unit is closed, but the lower wall of the body is provided with a -central aperture or opening 34 sufficiently large to admit insertion therethrough of any head 20 or 23. Radiating from this aperture, in the arms 30, are slots 35 extending into the portions 31. The width of the slots 35 are throughout their lengths greater than the diameters of the rods 15 and'22.. Therefore in assembling each head is inserted into the opening 34 simultaneously `with the insertion of its rod throughrthe slot 35, andthe rodis then drawn radially until the head abuts against the seat or wall 31. The head is slidable in its tubular arm.

Upon the marginal rows 17 and 25, in-

termediate their ends are connecting units 37 similar to unit 28 except one radial arm 30 is omitted, as shown in Fig. 6. Y

Ait the intersections of the marginal rows are corner connecting units 39 substantially like units 28 except that two adjacent arms 3() are omitted, as shown in Fig. 7, leaving but two radial arms.

rlhe bodies of the units 37 and 39 upon the end rows 25 have each spaced perforations 42 and 43 respectively, and the flange portions 11 of the bars 10 have series of perforations 45 spaced from each other greater distance than are those of the units 37 and 39. Pairs of supporting helical springs 47 have hooks 48 on one end in perforations 43, and hooks 49 on their other ends in adjacent perforations 45. Pairs of helical springs 51 have one set of end hooks 52 in the perforations 42, and the set of end hooks 53 in perforations 45. 1t will be noted that each of the pairs of springs 47 and 51 diverge from each other, and that the pairs 51 divergel at an equal angle from the rows 18. This arrangement of springs distributes the tension more effectively than if the springs were in alinement with the rows.

It will be observed that smooth movement is permitted between the rods and units, and that the entire fabric may be manually and easily assembled and disassembled. The upper faces of the units are smooth and unbroken.

I claim z* l. ln a bed bottom, the combination with a frame, of a bed fabric comprising rods provided with enlargements upon their ends arranged in longitudinal rows, rods pro-V vided with enlargements on their ends arranged in transverse rows, and connecting members comprising radial sockets engaging the enlargements and provided with Vertical slots to loosely admit the rods, and means for connecting the fabric with the frame.

2. n a bed bottom, the combination with a frame, of a bed fabric comprising rods provided with enlargements upon their ends arranged in longitudinal rows, rods provided with enlargements upon their ends ar` ranged in transverse rows, and connecting members at the intersections of the rows comprising hollow bodies provided with central openings in their bottom portions of greater size than the enlargements, and radial sockets on the bodies provided with slots of greater width than the diameters of the rods extending from the openings longitudinally and transversely of the sockets, and means for connecting the fabric with the frame.

8. ln a bed bottom, the combination of a frame, of a bed fabric comprising rods provided with spherical enlargements on their ends and arranged in rows, rods provided Y with spherical enlargements upon their ends arranged in rows intersecting the first rows, members at the intersections of the rows comprising radial sockets adapted to receive the enlargements and provided with oblong slots adapted to receive the rods, and means for connecting the fabric with the frame.

4. In a bed bottom, the combination of a frame, a fabric bed body comprising rods provided with enlargements upon their ends and arranged in rows extending longitudinally of the body, rods provided with -enlargements upon their ends and arranged in rows extending transversely of the body, connecting members slidably engaging the enlargements at the intersection of the rows, and pairs of helical springs disposed at an angle to each other and to the rows having their inner ends engaging the connectingmembers at the ends of the longitudinal rows, and having their outer ends engaging the frame.

ln testimony whereof l have aHiXed my signature.

EUGENE FULLER.
