COUCH SPRING CONSTRUCTION I Specification of Letters Patent. V Pate ted Feb, 22 1916 Application filed July 13, 1911. SeriaLNo. 638,324. 4

To all whom it may concern:

Be it known that I, JOHN HANCOCK, a citizen of; the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Couch Spring Construction, of which thefollowing is a specific'a tion.

This invention relates to spring constructions and particularly to couch spring constructio-ns.

The object of this invention is to provide novel means for securing the bottom of the various coiled springs in position and a further object is to form a meshed top in which the upper ends of the coiled springs are secured.

With these and other objects in view this invention is embodied in the novel construction, arrangement and combination of parts hereinafter described and as shown in the accompanying drawings, in which similar I reference characters indicate similar parts, and in which Figure 1 is a plan view of the couch springs, parts being broken away. Fig. 2 is a bottom view thereof, with parts broken away. Fig. 3 is a side elevation of a fragmental portion of the couch spring. Fig. at is a section on the line H of Fig. 3. Fig. 5 is a section on the line 55 of Fig. 3.

Referring specifically to the drawings, 6 designates a suitable wire frame and 15 designates the side beams of the couch. Flat cross bars 14 are secured to the beams 15, the said bars having their fiat faces arranged vertically and the extremity thereof being twisted to form an angular bracket 14: for securing the cross bars to the beams. spirally coiled springs 11 are arranged on the cross bars 14 and the lower volutions thereof are set in notches 16 in the upper edges of said cross bars. Longitudinal bars 13 are passed over the lower volutions of the intermediate rows of springs 11 and have a portion thereof dropped below the,

cross bars let as shown at 13 thus locking the corresponding springs in position. Longitudinal wire rods 12 pass over the lower volutions of the outer rows of springs 11 and pass through the apertures 15 in the cross bars and adjacent the upper edges thereof intermediate the notches 16 to lock the corresponding springs in position upon the cross bars. The ends of the bars 13 and wire rods 12 are bent downward to hook over the lower volution of the end spring as shown ati13 and 12 in Figs. 5 and 4, respectively. Y i

Strands of wire 10 and 9 extending lat= erally and longitudinally from the frame 6 pass diametrically below the upper volution-of the s rings 11. An accompanying wire strand and 8, respectively, at each side of the central strands 9 and 10, lie in a plane level below the upper volutions of the spring and each have portions 7 and 8 bent over the upper volutions of the springs and the intermediate portions pass underthe strands 9 and 10. The respective strands thus are woven together to form a meshed top for the springs in which the tops of the springs are rigidly secured. The ends of the various strands 7, S, 9, and 10 are all secured to the frame 6, the whole of which presents a suitable support for bedding or suitable covering.

The spring bed herein disclosed comprises the cross bar 14: provided with notches 16 in its upper edge and provided with an opening 150 lying entirely within the contour of the bar. The tie wire 12 is passed through the opening 150 and is held in its intermediate portion in the opening 150 against moving either upwardly or downwardly. In this regard the structure is of advantage over devices in which the tie wire is merely received in a kink or bend of another wire. The lower convolution of the spring 11 rests in thenotches 16 and is extended beneath the tie wire 12 upon opposite sides of the opening 150. The bottom of the opening 150 lies in approximate alinement with the bases of the notches 16, therefore, the friction between thespring 11 and the tie wire 12'is lessened and the spring may be rotated readily to cause its lower convolution to engage beneath the tie wire 12. However, as the spring 11 is rotated, (being of spiral form) it will bend the tie wire and cause a firm engagement between the spring and the tie wire. The feature above mentioned is of advantage since, in

the spring is made, whereby when the spring i is rotated, the lower a convolution thereof 15 i may distort the tie wire and form therein seats with Which the said lower nonvolutioln of the spring engages.

In testimony that I claim theforegoingas my own, I have heretoafiixed my signature 20 in the presence of two witnesses.
