' SPRING.

T 0 all whom itmcty concern:

Beit known that I, CHARLES EDGARMAN- NERS, a'subjectof His Majesty the King of Great Britain, residing: at Glenville Glen, Crafers. in the State of 1 South Australia, in the Commonwealth of Australia, have invented certain new and useful Improvements in and Connected With Springs, of which the following is a specification. v

My invention relates to improvements in and connected with springs and is intended to apply more particularly to what I are termed coil springs and half-coil springs for furniture and upholstery and for the cushions of motor cars and the'like.

Hitherto springs ofthis nature-have usually be'en held in positio-n'by strips of webbing to which they have been-stitchedor to a lining of Hessian or other fabric, and more recently cross wires have been introduced been attached by metal clips.

The special object of my invention is to construct the springs in such a manner that they contain means for attachment to; the wires of the frame as an integral portion of the spring, anauxiliary attachment being provided if so desired to assist in keeping the springs in their relative positions.

In carrying my invention. into efiect I form loops, recesses or hook-like structures in suitable positions by twisting or bending the spring substantially in the manner hereinafter' described and as illustrated in the accompanying drawings wherein Fig. 1 is a side elevation of a spring.

Fig. 2 is a plan of Fig. 1.

Fig. 3 is a plan of a spring showing different arrangement of the bent or looped portions for use with parallel frame wires.

Fig.4 is a plan of a spring with loops for cross wires also showing attachment to an adjacent spring.

Fig. 5 is a side elevation of a spring showing cross wires engaged in loops or kinks.

Fig. 6 is a side View of a spring showing cross wires engaged in hook-like formations whichare-bent upon inturned top and bottom ends of the spring wire.

Fig]? is a plan showing the upper por Specification of Letters Patent. Pate t ed F b 77, 1922 Application filed August 26,1920. Serial No. 406,099.

Fig. 9 illustrates the hook portion of inturned end after it has been finally bent and of reference are used to denote similar or corresponding parts wherever they occur. v

In the drawings the colls of the wire spring are indicated by the reference "letter a, the

spring being either of spiral construction as n F 1g. 1 or it may consist of rings of equal diameter as in Fig. 6.

In Figs. 1, 2 and 4 I have illustrated loops or eyelets 6 arranged at right angles round the periphery of the spring wire by merely bending the wire upon itself as clearly indicated, the loop thus formed being of justv fsuificient diameter to accommodate the cross wire 0. In Fig. 3 I have shown two similar loops'opposlte to each other, but the corresponding' loops which are'at right angles are twisted or deflected outwardly so thatif thev frame is built up of parallel wires they can readily be accommodated in the side loops as will be well understood.

It may not always be necessary or convenient to form complete loops or eyelets in the periphery of the wire and I have therefore provided for the accommodation of the cross wires in kinks or recesses correspondingly marked 6 in Fig. 5 and likewise arranged at right angles to each other. These are preferably bent alternately upwards and downwards, the arrangement being such that the cross wires in combination with the spring interlock each other and prevent displacement without'necessitating an :as shown in plan in Fig. 8. i The portion which forms the loop is then bent downwards at right angles to the part a and.

the free end marked a in Fig. 8 is also bent downwards parallel to the loop bend so as to form an arch. This structure provides for the accommodation of both cross wires in the centre of the spring as will be well understood upon reference to Fig. 9 of the drawings.

In Fig. 4 I have shown a small bridgepiece at d for keeping adjacent springs in their relative positions. This bridge-piece is not for attaching the springs to the cross wires but is to preventtheir displacement on their mountings as ithas been found in connection with some attachments that the springs sometimes work apart and in other cases they come together and cause rattle. The bridge-piece for this purpose may have slots or holes at each end to facilitate its attachment to the structure so that the cross wires will not form an impediment, but it is turned back upon itself so as to embrace the spring wires and can be cleated with the aid of pliers or other implement in order that it may firmly hold the spring wires and stood that this may be furnished with loops or hooks of the nature already described, or

a single or double loop or hook may be 7 formed thereon, and that the bent 'or looped end shown in Fig. 8 may be used to' support a supplemental attachment.-

Having now fully described and ascertained my said invention and the manner in which it is to (be performed, I declare that what I claim is A device of the character described including upper and lower crossed frame wires extending substantially at ri 'ht angles to each other, and coiled springs interposed between said upper and lower frame wires and having their axes substantially aligned with the intersecting points of said crossed frame wires, each of said springs being provided with an inwardly projecting end portion bent back upon itself to form a hook having an open end and a closed end, the closed end being substantially below the planerof said inwardly bent portion and an intermediate portion of said hook being arched upwardly to overlie one of said frame wires and at opposite sides of the other cross frame wire, said closed end of said hook being engaged under the last hamed. cross frame wire, whereby the hook and said crossed I frame wires are interlocked against lateral displacement.

In testimony whereof I affix mylsigna- 6O
