This invention relates to spring supporting frames for beds and the like and it comprises a spring supporting frame having opposite side and end members, the side memberssbeing provided with 'a'jseries of opposite slots, cross bars provided at opposite ends with lips arranged to engage the slots, said lips passing through the slots' and being so formed as to project downwardly and outwardly in order that the bottom face of a portion of the lip shall rest upon the top face of the side member and the top face of the end portion of the lip shall rest against the under face of the side member; all as more fully hereinafter set forth and as claimed.

In the manufacture of spring frames for beds and the like the frames are usually made of angle iron and the spring supporting bars are usually attached by riveting, welding or the like. This mode of manufacture is comparatively expensive and troublesome and it is one of the objects of this invention to simplify the manufacture and assembling of such spring supporting frames by eliminating the necessity of welding or riveting of the bars.

Another object of this invention is to provide a spring supporting frame which will accommodate springs of greater depth than ordinarily used and at the same time will not result in a finished bed spring the top of which will extend too high above the sides of the bed. This object is attained by shaping the transverse cross bars for supporting v the springs so that they extend a suflicient distance below the main frame,-

In the accompanying drawings, I have shown one form of a specific embodiment'of the invention.

Fig. 1 is a segmental detail perspective illustrating the method of assembling the cross bars with the frame.

Fig. 2 is a transverse section through the frame showing one of the spring bars in side elevation and showing the spiral spring and upper frame; and I Fig. 3 is a segmental enlarged perspective of one of the ,spring supporting bars.

The spring supporting frame comprises an an 1e iron member having horizontal face .1, an vertical face 2, the horizontal faces 7 being provided with a plurality of slots 3.

The spring supportingbars are particularly adapted for use with an angle iron frame such as described; The spring supporting bars are made of one piece of metal having horizontally disposed lowerportion 4 and upwardly extending sides or intermediate portions '5, the lower portion and the sides of each bar being twisted with respect to each other as is shown at 6' for purposes of reinforcement and also to dispose the wide faces the lower portion of the bar in a vertical plane. The ends 7 of the bar extend in a general horizontal plane with the ex treme ends bent downwardly as at 8 and forwardly as at 9. The length of the slots 3 of the frame corresponds to the width of the bars at the extreme end. The; lower portion of each bar is provided with a pluralityof holes 10 each of which is adapted for. the reception of one end of a coil spring 11 which is anchored to the frame 12 forming the upper portion of the bed spring. As made, each bar is provided at one end with a downwardly extending lug or lip in order that the bars may be easily and readily. assembled with the frame. To assemble a bar with the frame the end which-is provided. with the downwardly and. forwardly bent. portion (shown at the left, in the drawings) is inserted in a slot, the bar being held in substantially avertical position. The bar is then lowered so that the horizontal portion 4 is positioned below the frame and so that the upper face of the horizontally extending end 9 bears against the under face 1' of the main frame adjacent the slot and the under face of the end 7 rests on top of the face 1 of the main framev adjacent the slot. 'The.

downwardly extending lip at the other end of the bar is inserted in the oppositeslot of the main frame and advantageously the downwardly extending lip is then bent out wardly as is shown in Fig. 2 (to theright) so that it corresponds to the other end-"of the bar, resting above and below the hori- Cross bars such as described are particularly useful in connection with bed spring frames made of angle iron as described and when the bedframe is to be of a construction wherein the coil springs are supported at points below the bed frame, the shape of the ,end of. the bars facilitates assembl-ing the parts. The provision of'bars having horisite ends with lips arranged to engage the slotsg'the lips at one end-projecting downwardly and slightly outwardly longitudinally of the bar andthe lips at the other end projecting substantially downwardly whereby the downwardly and outwardly project-- ing lips may be inserted in one slot of the side member in downward direction and the bar then lowered so that the other lip may be inserted in the other slot, whereby the bar canbe permanently 'aflixed to the frame by a 'singlebending operation upon the downwardly turned lip.

In testimony whereof, I have hereun'to afiix'ed my signature.
