To all 'whom ttmay concern.

Be it known that I, JAMES F. MCCLATCHEY, of Kenosha, AWisconsin, have invented a Bed-Bottom, of which the following is a l to sag bylong use, and theseveral elements of which yield mde endently of one another,

whereby a personying or resting on,v one side of the bed, or falling thereon suddenly, will not tend to displace, raise or otherwise disturb a person resting on the other side of the bed.

I also aim, as further objects, to produce a bottom which will have a substantially smooth surface, and which shall be absoluteliy free from any kinks or cavities giving a lo gment or hidin -place for vermin.

I also aim to pr uce such a bottom at a moderate cost, cheaper in fact than other forms of bed-bottoms not having these advantages. y n

With these objects in View the invention consists ofthe constructions Aand combinations `hereinafter more particularly described and set forth in the claims, reference being had to the accompanying drawings, which show a bed-bottom constructedaccording to my invention.

In these drawings, Figure I is a plan view of the bed-bottpmf. Fig. 2 is a side elevation thereof. -Figw is a plan View 0f one corner thereof on alarg'er scale. Fig. 4 is a transverse section through the same, substantially on the line of one of the longitudinal wires; and Fig. 5 is a schematic cross-section to illustrate the mode of construction. Figs. 6, 7 and 8 are substantially lateral edge views of a portion of the fabric used in my bed-bottom showing the successive steps of bending the unselvaged end edge ofthe fabric over to fasten the same.

`In these drawings every reference character refers always to the same part.

The bottom shown in the drawing is a rigid one, such as -is used in an ordinary bed, and it will be understood that for furniture such as davenports, couches etc. requiring foldin bottoms, the bottom will. be made in hinge sections, folding upon one another as will hereinafter appear. As shown, the

frame .comprises four angle-bars a a and b b, constituting the sides and ends thereof, united at the corners by screw-bolts c and maintained in rectangular shape by diagonal braces d. The mattress-support consists of longitudinal wires spaced at regular intervals from side to side of the bed, these being provided at their ends with hooks or eyes f (see Fig. 3), which engage with a serlesv of coiled springs g provided with hooks g', g2, at each end thereof, the ends g engaging with the eyes f, and the ends g engaging in holes b formed in the upstanding ianges b2 of the end-bars b of the frame. I'prefer to provide a spring g at each end of each wire e to connect it with the frame;

but it is obvious that the device will work, l

consistently with my invention, if the springs at one end are omitted, the wires e bein connected 'directly to the frame orby rigi links. u

AS thus far described the bed-bottom is sufficient to support the mattress; but it would have the defect that the wires would be la t to spread at the oint supporting the .wei t upon` the bed a owing t e mattress to fouble'up between the wires and fall between them. To prevent this and hold the l wires properly spaced I provide a helical wire-fabric 71., consisting of rows of helically wound interlinked longitudinal wires,

through the coils of some of which' the wires e are made to pass, thus holding them at the proper spacing and preventing them from separating beyond a ven distance.

It isto be observe that the wire-fabric 71. in my.+bedbottom, contrary yto the disposition of `similar fabrics of other forms of bed-bottoms, is not stretched elastically and does not perform the function .of a support,

but merely cfa flexible spacing medium for.

tening here shown...isv a novel one which.

poesses the advantages over previous methods., both of' greater cheapness and also of being formed entirely of wire, whereby no hiding places are left for vermin. This method of fastening consists in providing the portion h3 of the fabric opposite the lap being likewise flattened out to some extent as may be necessary or deslrable.

The curling ends of the lap h interlock and engage with the wires of the laps h2 and h3, which'effectively holds the wires and prevents them from coming loose. In addition the ends of the Wires e underlie the laps la and 11,2 and the wires i and prevent them from unbending. Further security against this effect is obtained by forming upon the ends of the wires i eyes z" which engage the Shanks of the outside wires e, and are themselves engaged between the coils ofthe series of helical wires c which form the selvage of the fabric. The endsof the wires j are likewise vpreferably formed with eyes j', which are best arranged to underlie the eyes f of the outside wires e. I may form this fastening more simply, b withdrawing the cross-wires z' altogether a ter the fastenin is otherwise set up, but it makes a betterjob to leave them in place. A further advantageous improvement on this construction consists in passing the wires i and 'j through the meshes of the fabric-instead of under the latter, after which the laps h', h2 are bent i between the wires thereof before thewire is bent over; Fig. 7 shows the same fabric after the rst lap h has been folded around lthe wire i; and Fig. 8 shows the same after the wire z' and lap h2' have been folded around the wire j. To avoid confusion,- only two adjacent wires of the fabric are shown in these figures. v

As the wire-fabric h is not stretched (it is of course sufficiently pulled out to hold it smooth and level), and is perfectly flexible, the lateral elements of the bed-bottom will be substantially independent of one another, more especially if the wires in the fabric are set closer together laterally than the diameter of the coils, so as to allowv a certain slight amount of spreadin or separation of the wires e,such as wouId result from a depression of some of them due to the weight of a person on that side of the bed, without y drawing over or affecting in any way the w1res on the other side ofthe bed. As moreover the support is entirely from the and linked together by eyes atthe folding points of the frame.

As previously stated, all the improved features as herein-described are not essential to the substance of my invention, but such variations may be made within the scope thereof as will be indicated by my claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: p

' 1. In combination with a helical wirefabric, a pair of Wires transverse to the wiresv constituting said fabric and parallel at a short distance from each other, the uuselvaged ends of said fabric being turned first over one wire and then over the other forming'three interengaging laps, the wire ends in the intermediate lap engaging between the wires of the vtwo outer laps.

2. In ai bed-bottom and the like, a fastening for the unselvaged end of the wire-v fabric comprising a transverse wire over which a lap of the unselvaged edge is turned, and a plurality of longitudinal Wires underlying said lap and holding it in position.

3. In a bed-bottom and the like, a fastening for 'the unselvaged edge of a wire-fabric comprising a transverse wire over which a lap of the unselvaged edge is turned, a second transverse wire over which said lap, said first wire, and also a second lap ofthe edge are turned, and a plurality of longitudinal Wires underlying bothsaid turned laps and holding them in position.

4. In a bed-bottom and the like, a fastening for the unselvaged edge of a wire-fabric comprising a transverse wire over which a lap of the unselvaged edge is turned a second transverse wire over which said lap, said first wire, and also a second lap of the edge are turned, and a plurality of longitudinal wires underlying both said turned laps and holding them in position, the ends of said first transverse wlre having hooks engaging around the outside longitudinal wires whereby said transverse wire and elastic fabric engaged thereby are held in position.

5. In a bed-bottom, a frame comprising longitudinal bars and transverse angle bars having each an upstanding flange on the llO outside edge thereof, a. plurality of coiled of springs at opposite ends of the bed, a helical Wire-fabric havingA longitudinal interlinked helically Wound Wires through the coils of some of which said longitudinal wires pass, and a pair of transverse Wires crossing the ends of said longitudinal Wires Iand engaged by said springs, the unselvaged edge of said helical Wire-fabric being engaged with and heldby said transverse Wires.

6. In a bed-bottom and the'like, afastening .for the unselvaged edge -of a helical Wire-fabric comprising a transverse Wire interlaced With the meshes of said fabric parallel to said end edge and at a short distance therefrom, the portion of said endedge beyond said transverse wire being then folded over upon the fabric `itself.

7. In a bed-bottom vand the like, afastening for the unselvaged edge of a helical Wire-fabric comprising a transverse Wire interlaced with the meshes of said fabric parallel to said end edge and at a short distance therefrom, the portion ,of said endedge beyond said transverse'wire being then foldedover upon the fabric itself; and a second transverse wire likewise interlaced with the meshes of said. fabric parallel to 'the first and a short distance farther from the edges than the latter, the portion of the fabric beyond said second wire including said fold around" the first Wire being then folded back upon the fabric itself.

8. In a bed-bottom and the like, a fastening for the unselvagd edge of a helical Wire-fabric comprising a transverse Wire interlaced With the meshes of said fabric parallel to said end edge and at a short distance therefrom, the portion of said end-edge beyond said transverse Wire being then folded over upon the fabric itself, a second transverse Wire likewise interlaced With the meshes ofsaid fabric parallel to the first and a short distance farther from the edges than the latter, theportion of the fabric beyond said second Wire including said fold around the first Wire being then folded back upon the fabricitself; and a plurality of lon itudinal Wires interlaced longitudinally wit the meshes of said fabric up to a point near said end fastening and from there passing under the folded overlaps of said unselvaged end, in conjunction with means for holding said longitudinal Wires and said second transverse Wires together at the point Where the longitudinal Wires meet the transverse wires, whereby to hold the end folds in place and prevent them from unfolding. In Witness whereof, I have hereunto set my hand this fourteenth day of October,

JAMES F. MGCLATCHEY. Witnesses:
