SPRING BED BOTTOM.

Specification of Letters Patent.

Patented Apr. 13, 1915.

To all whom it may concern Be it known that I, JACOB H. Hinscn, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented new and useful Improvements in Spring Bed-Bottoms, of which the followin is a specification.

This invention re ates to improvements in spring bed-bottoms and consists in certain peculiarities in the construction and arrangement of parts, and in certain novel combinations of elements substantially as hereinafter described and particularly point ed out in the subjoined claims.

More especially the invention relates to a fabric which is composed in part of helically coiled springs from which the resilience of the fabric is obtained and in part of a new combination of members of different though related shapes and not esentially of spring or resilient character, the said members being so constructed and combined or correlated that the'mesh will be composed of substantially diamond-shaped sections formed in a simple, practicable and economical way, with a view of producing a fabric which will readily yield to weight, will possess maximum strength, will retain its shape and may be economically manufactured, and one in which any strain imposed on any part thereof. will be transmitted throughout a maximum area.

In the accompanying drawings, wherein like characters of reference denote corresponding parts in the several views, I have illustrated the preferred embodiment of the present invention, but it should be understood that changes in the details .of conof one transverm frame member and the struction may be made without departing from the spirit of theinvention or the scope of the subjoincd claims.

In said drawings :-Figure 1 is a plan view of a link spring bed bottom constructed in accordance with the present invention, showing an end of the upper web or flange vertical partof said member in section to disclose a desirable way of connecting the corner riser or support thereto. Fig. 2 is :1 detail side elevation of one corner of the frame: and Fig. 3 is a vertical sectional Vlt'W of the latter.

The frame comprises two longitudinal side uwzubu-s. i, It, and transverse end members i3. 53'. the transverse members being supported from the longitudinal members in a plane higher than the latter by corner brackets or risers each of which is marked C. Each longitudinal framemember is preferably of tubular form and each transverse member is preferably of angle-form. Each corner riser or bracket has a suitable part, as the sleeve 10 for example, by which it is connected to or mounted upon the end of a longitudinal member A, and also has an outwardly and upwardly curved part 11 whose upper end is provided with a flange 12 against which the adjacent transverse member ll or B rests. Each corner bracket or riser further has an 7( outwardly projecting lateral lug 13. These lugs support the bed bottom from the side rails ot'the bed-stead, as is usual.

In order to prevent axial movement of the corner brackets or risers upon the i rounded surfaces of the longitudinal members A, A, the latter are formed with apertures 14 and the corner brackets or risers have inward projections 15 arranged to be seated in said apertures.

The transverse members B are secured to the flanges 12 of the corner brackets or risers by the lugs 16 projecting from the latter into apertures l7 formed in the transverse mcmbers,'said lugs being preferably of such nature that after they have been inserted in the apertures 17 their outer ends may readily be upset, by a hammer or other appropflate tool, to prevent separation oi the transverse members B therefrom.

The described construction of frame is one which I prefer but it will be understood that changes therein may be made without departing from the spirit of my invention, the features of the bed bottom with which my invention is particularly concerned being iii the fabric, including therewith, or as a part thereof, the means for connecting the same or the mesh part thereof with the frame.

The fabric comprises mesh portion which 100 is composed of a series of transverse members D. each of which extends continuously across the fabric: a transverse member E at one end thereof, this similarly extending continuously entirely across the fabric: a series 105 of ii-shaped members i at the other end of the fabric: and a series of lines of diagonally arranged links ii, some of which (G) con nect the transverse members I) with each other and others of which (i i) connect one transverse member D with the transverse member. E, the transverse members D being spaced apart along the length of the fabric and the one nearest themember E being spaced from the latter.

Each of the transverse members a D is formed of a wire of suitable character bent to form two outwardly extending arms 20, 20 at the ends thereof, a series of alternating arms 21 and arranged diag'onally-respectively extending toward the right and lcft-and lateral elements 23 and 24 arranged between the arms and connecting their-ends to each other, the elements23 being arranged in line with the outwardly-e25 tending ends 20 and the elements 24 being arranged at the opposite ends of the arms. The ends of each connecting element 23 and 24 at their junctions with the arms 21 and 22 are offset to form two seats 25 and 26 for a purpose which .will hereinafter appear. ()ther seats 27 are formed at the junctions of the outside arms 21 and 22 respectively with the ends 20. It will be noted that atransverse member D thus formed presents a series of spaced-apart sections each composed of arms '21 and 22 and a lateral connection 24, arranged alternately with a like series of. spaced apart sections, composed of the same arms 21 and 22 and a lateral connection 23. It will further be noted that the relative arrangement of the transverse members D is such that in the completed fabric the firstmentioned sections are arranged in lines with each other longitudinall of the fabricthere being a series of suc lines corresponding to the number of said sections in each transverse member, as is apparent-and that the second mentioned 8801310118, (e. 9. those formed of the side arms 21, 22 and the lateral elements 23) bear a like relation to each other.

The members D are connected to each other by the intermediate links G whose ends are of hooked formation and are arranged in the seats at the closed ends of the sections formed by the arms 21 and 22 and the lateral connecting elements 23 and 24. Each transversc'li'ne of said links is composed of a series of "links extending alternately toward the rightand left-those which extend toward the left being interposed between the arms'2lof two members D while those-which extend toward the right similarly are interposed betweenthe arms 22 of said members. The meshes thus formed of the members D and (l are of approximate diamond shape, as will be seen. y

The member 1'] forming one end-of. the fabricdiil ers from the membersD inthat each pair ofits alternating arms, marked 31 and converge to a point at one end, marked 34. These points,i which form apices of V'-.-.l-iaped section-s..take the place'of the lateral bcnds'iiin themembers D and serve I bottom-to sustain any; strain which is as means whereby the members E' may connected to ailine of helically coiled springs H by which one end of the fabric is yieldably supportedirom the contiguous transverse frame-member B. In otherrespects the member E is like each member D, its V-sha ed sections being connected to each other y lateral elements 33each of which is bent'to form seats 35 and 36 at the junctions of its ends with the arms 32 and 31 respectively of the V-shaped sections of the member, and said member also terminating at each end in an outwardly-extending arm 30 each having a bend 37, the said bends 37 forming seats at the junctions of the arms 30 with the adjacent side arms'31 and 32 respectively of the V-shaped sections at the endsof the member E. The member D atthis end of the fabric is connec'ted to the element E by a line of diagonally-arranged links G, the-said links extending alternately to the right and left as herembefore described. v 7

The members F, which are arranged at the other end of the fabric, are each separate from every other and each is approximately V-shaped,\being composed of two converging arms 41 and 42. Their closed'ends or apiws 43 are engaged by helically coiled springs H b which this end of thefabric is yieldably supported from the transverse ,frame member B. The

free ends of the outer arms 41.and 42, re-

spectively, of the outer members F are hooked into the seats 27 formed. by the bends at vthe junction of the outer laterally-extending ends 20- and adjacent ding-lnal arms of the adjacent member D. l

I the other arms of said members F are hooked over-the bends 25 and 26 at the junctions of the lateral elements 23-.and diagonal arms 21 and 22 of said member D. The diamondshape of the mesh is thus continued to, or retained at, this end as well as at the other end and throughout the body of the fabric.

- tures to receive the ends of the arms 20 and 30, the ends of the latter being preferably of hook-form. to retain them in engagement with the longitudinal members. These longitudinal members serve, as edging strips for the mesh portion of the=fabric, enabling the laced upon its edge without permanent de irmw, tion -thereof,- and they also prevent permanent deformation of the interior meshes of the fabric from use.-..-,
