Specification of 'Lettei's Patent. Opt,

Application filed septmber s, 1915. "Serial No. 50,316.

To all whom it may concern:

Be it known that I, WILLIAM W. NoL'r1nG, a citizen of the 'United States, residing at" Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Bed- Springs; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to bed springs, and has for its object to provide an improved bed spring which will have all of the resilience due to the customary woven wire fabric or other mattress supporting cushion, and in addition thereto, will have a further and independent resilience or yielding action. This latter noted resilience or yield ing action I accomplish by supporting the entire spring frame with auxiliary suspending springs. These auxiliary suspending springs are preferably applied as a yielding connection between the spring frame proper, or upper frame, and a lower or sub-frame,

which latter will be supported on the bed frame.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Figure '1 is a view partly in end elevation and partly in transverse section, showing my improved spring structure'applied to an ordinary iron bed; and

Fig. 2 is a vertical section taken through the spring structure, from front to rear, on the line a m ofFig. 1.

The numeral 1 indicates the end members and the numeral 2 the rails of an ordinary iron bed.

So far as this invention is concerned, the rectangular frame of the bed spring proper may take various forms, but as shown, it is made up of angle iron end bars 3 and tubu lar metallic side bars 4. Also, the spring cushion supporting the mattress may take various forms, but as shown, is in the form of a wire fabric 5 anchored to the end bars 3 in the customary or any suitable way. The end bars 3 are provided with rigidly secured depending arms 6, the lower ends of which are connected by cross rods 7 The lower or subframe of the spring structure, as shown,

is made up of angle iron bars, to-wit, of

longitudinal bars 8 and transverse end bars 9, the latter of which project'at their-ends 'and rest upon the bed rails 2. The upper or main frame is supported from the subframe by a multiplicity of springs.

springs are preferably coiled springs l0,'the,

The

lower ends of which are suitably anchored to the cross rods 7 of the upper frame structure, and the upperends of which springs are detachably anchored to hanger brackets 11, bolted, or otherwise, rigidly secured to the end rails 9. The depending arms 6 work quite close to the said cross rails 9, and hence, prevent endwise swinging movements of the floating upper frame of the spring structure. At the same time, the said springs 10 yieldingly support the entire upper spring frame and give the same a resilience that is additional to and independent of that which is given to the mattress by the netting or cushion 5. More or less of the springs 10 may be applied, in the manner above illustrated, so that the upper spring frame may be supported with greater or less resilience, and this distribution of the said springs 10 may beequal on both sides of the spring, or it may be unequal,

when desired. c

The depending arms 6 and cross, rods 7 constitute end brackets carried, by the upper frame and depend to points, below the lower frame so that the said upper frame maybe suspended from the lower frame by coiled hanger springs, or the like. i

.My improved spring mechanism herein described is especially adapted for use as a bed spring, but is capable of other uses, such, for example, as a spring cushion for sofas, and similar articles of furniture.

What I claim-is:

L'A mattress support comprising upper and lower frames, the former having a mattress supporting surface that is in itself resilient, and the latter having parts adapting it to detachably rest on the rails of a bed, said upper frame having depending brackets that extend below the ends of said lower frame, hanger brackets secured to and projecting from the said lower frame, and

a multiplicity of coil tension springs anchored at their upper ends to said hanger brackets and attached .at their lower ends to the depending brackets of said upper frame. I

2. A mattresssupport comprising upper and lower frames, the former having a mat tress supporting surface that is inqitself to said upper frame and depending there-'- from past the ends of sald lower frame, andf' sa d cross rods connecting the lower ends of" said arms han 'er brackets secured to and a a i i n prqectmg from the ends 0i said lower frame, and a multipllcity of co led tension Gopiesof this patent may be obtained for springs anchored at their upper ends to said hanger brackets and attached at their lower endsto said cross rods.

In testimony whereof I alfix my signature in presence of two Witnesses.
