Claims o1; 5 201) This invention relates'to all rn'e'talbed springs.

The "conventional bedspring ofthis type consists of'apair of headersjone at each end,fwhich are separated and held inposition by side rails whicharerigidly connectedat each corner to the headers bymeans of a malleable iron casting. Thearrangement 'of. slats or cables and springs, hereinafter described as the spring fabric, 1s connected tothe headers and tends to drawthem towards each other. A disadvantage ofthis constrluotion is'that under present war conditions the malleableiron castings are no longeravailable; V1

The object of the present invention is to pro-- vide a connectionbetween the side rails and the headers which dispenseswith the conventional malleable castiron corner, while att'he same time permitting ready assembly and taking down" of the liiiits so that the side rails, the spring fabric and theheaders may be shipped as separate units thereby saving in shipping "and storage costs. fA bedspring according to the invention therefore comprises "essentiallya header at each end, a conventionalfspring fabric. connected to each header andfurg'ing' the two towards each other, "sideflrails and means connectingjthe side rails to "theliaderslat the four corners of the bedspring comprisinga connector member connected to the header near the end and extending "downwardly therefrom, this connector member having aj substantiall vertical slot formed therein adapted to receive the end of a side rail, each end lofeach rail being formed, at the sideremote from the spring fabric, to engage both sides of the *connector member at the bottom of the slot, and, aftersuch engagement'to engage the inside of the 1 connector memberat the top of the slot at the side 101" the rail closer to the spring fabric.

According to the preferred modification the side rails are tubular and are fiattened at the Lend to cooperate with a substantially rectangular ."slotvformdin the connector member. At the top corner of each fiat portion each of the side railsis cutbackto iorm a shoulder which engages the inside face of the connector member. At the 3 bottom each fiat portion is provided with a notch or a size corresponding roughly to the thickness of jthe, connector member and the distance between thebase of the notchand the foot of theshoulder ista. little lessthan the length of the slot. The {spring fabric holds; the connector members against the shoulders and lthevinotches together withthe shoulders limit movement of the headers gurgedm the pri g iabric towardseach Other.

According-to'the preferred modification the stabilizer member is bent at thelower end substantially at. right angles and extended laterally of the spring and substantially.=horizontally to forma corner'support adaptedto rest on a bed frame. According to-a further feature of the invention the wing of the connectormember riveted to the'headerison the inside andit is longer than theother win g so that-itextends down inside the part of the bed frame on which. the corner support-rests thereby preventing the spring from sliding 01f the bed; 1 A protective cover is provided secured at the top to theunderside of the header and at the bottomto the top side of the corner support. 1 v --The invention willnowbe-des'cribed with reference to the accompanyingdrawings in which protective cover; V A

The side rails 18 are of tubular steel and are fiattenedat the ends .(see Figure. l.) .to correspond approximatehr tofia rectangular slot: Iii-formed in the wing of the member l4 and arranged with its longitudinal axis running straight up and 7 down.

Referring to Figure 3 it will be seen fihaltithe top corner of the flattened end .of the side rail 18 is cut back to form a shoulder 2ll' an'd that thebdt tom of the flattened end of theaside nalil is'prd -i than the wing l5 of the member l4 so that the former extends down along the inside of the portion of a bed frame on which the extension 24 rests, and thereby prevents the bed spring from sliding oil the bed.

In order to improve the appearance of the corner and to prevent bed clothes and the like from being caught, a protective corner member 25 is welded at the bottom to the top face of the extension 24 and at the top to the bottom face of the horizontalfiwingnof header in,

It will be appreciated that the winglii of the .member [4 need not necessarly be straight as shown but may be formed into an S or similar vided with a notch 2| corresponding. approxi mately in width to the thickness of the angle member Ma; Thenlengthioithe SlQtwQ is slightly greater than: the; distance.between the. base: -.of SldOiZ'Qhiglf and ithe iioot of the shoulder 20 and theremainingto borheris rounded.
