To all whom it 'may concern:

Be it known that I, MAX IIODELL, a citi'- My invention relates to improvements in spring mattresses and particularly to imlprovements in the construction of the end ars thereof.

The main object of my invention is to strengthen the structure while at the same time reducing the weight thereof, and I attain this object by constructing the end bar of anj gle iron and providing a peculiar form of truss for that flange of the angle iron to which the spring fabric is secured.

A further object of my invention is to simplify the construction and reduce the cost of manufacture of the device, and to this end I connect the ends of the truss rod to the angle iron by passing them through holes in the angle iron and wrappin them laterally around one of the flanges. y this means I avoid the use of expensive attaching means while at the same time produce a strong and unyielding connection.

In order that my invention may be fully understood, I will lnow proceed to describe an embodiment thereof, having referenceto the accompanying drawings illustratin the same, and will then point out the nove feaj tures in claims.

In the drawings: Figure 1 is an under side view of the end portion of a spring mattress constituting an embodiment of my invention. Fig. 2 is a view in cross section kthereof upon the plane of the line 2,-2 of Fig. 1. i

Fig. 3 is a detail sectional view upon the line l 3-3 of the portion of mattress shown in Fig. 1.

The mattress frame comprises end bars 10 of which one is shown in the drawings, side rails 11 and corner blocks 12 having sockets 13 for receiving the ends of the side rails. The an le bars are secured to the corner blocks gy means of rivets 14fin the usual manner.

The angle iron 10 comprises two flanges.

15 and 19, one of which is dis osed 'horizontally, and the other, vertica y. A sring f fabric 16 is connected to the horizontal ange 15 by means of 1in-ks- 1s which engage the edge ofthe flange 15 and a marginal stri 17 with which' the spring fabric is provi ed.

By this means the spring fabric andthe flange 15 lie in substantial the same plane while the ,flange 19 is dependent therefrom at substantially an angle of ninety degrees. The construction so far described is common and well known in spring mattresses, except that the, angle iron 'is usually very Amuch heavier than that shown in the drawings.

This is because the tension of the spring fabric is very considerable even when there is no load carried thereby, and this strain is, of course, considerably greater when the mattress is in use. In order to enable a light angle iron to be used and to prevent deection in use, I have provided a truss member 21, here shown as in the form of a rod. This truss member lies flat against the under side of the flange 15 and is passed at its ends through holes 22 formed at substantially, the junction of the two flanges 15 and 19, the extremities 23 of the truss rod being wra ed laterally around the flange 19, all as wfllpbe well understood by reference to the drawin s. The flange 19 is provided at a point midway between its ends with a laterally projecting stop or stud 20 near its outer edge, the said truss rod being arran ed to engage the stud whereby it is held in t e proper position to constitute an effective reinforcement or truss for the angle iron. It will be noted that because of the fact that the rod lies close against the inner face of the flange 5 andis kept distended' by means of a laterally projecting stud or stop upon the said flange, the bracing is edected substantiallyv in the plane of tension and any tendency of the angle iron to spread, such as mi ht be apt to occur if the bracin were eifecte from the flange 19, is obviate What. I claim is:

1. yIn a spring mattress, the combination with a spring fabric, of an end bar comprisin 'an angle iron having horizontal and vertica flanges, the said spring fabric being connected to the said horizontal flange, and

lying substantially in the plane thereof, a .truss member secured at its o posite ends to the angle viron at substantial y the junction ofthe two said ilanges, and a stud rojecting l laterally from the said horizontal ange near lts outer edge, for engagement with the truss member intermediate its ends, the said truss member lying substantially lat a ainst the under face of the Said horizontal f ange. 2. In a spring mattress, the combination with a spring fabric, of an end bar comprisin an angle iron havin horizontal and vertida flanges, said spring abric being connected to the said horizontal an e, and lying substantially n the plane t ereof, a truss rod having its ends passed through holes at substantially the junction of the two said flanges and wrapped transversely around the vertical flange, and a stud projecting laterally from the said horizontal flange near its outer edge, for engagement with the truss member intermediate its ends, the said truss rod lying substantially flat against the under face of the said horizontal lange.
