2 Claims. (CL 155-179)
The invention relates to improvements in spring and, furthermore, that in the event that said

A suitable embodiment of the invention is illus
means other than helicals, or the equivalents of
said helicals, may be employed to couple each
trated in the accompanying drawing, wherein
Fig. l is a plan view of a, spring assembly con
structed in accordance with this invention.
Fig. 2 is a side elevation of the same.
Fig. 3 is a fragmentary end elevation of the
same.
The structure of the present invention com
prises a series of parallel strips, each composed of
` 15 wire bent to zig-zag form to provide substantially
Vilat skeleton surfaces upon which padding mate
rial may be supported. n
Each of the said strips is composed, preferably,
of a single strand of wire of suitable type and is
20 bent to present substantially parallel upper and
`
strip with the next adjacent strip. f
While I have illustrated the strips as being
composed of a single strand of wire each bent
substantially as illustrated in Fig. 2, it will be
obvious, of course, that each strip may be com
posed of a plurality of parts and joined at the
points 8 in any suitable manner.
In bending the strips when composed of a single
strand of wire, as illustrated in Fig. 2, I prefer
to twist the laterals l at the ends of the upper
and lower portions l and 2 respectively about
their own axes, this twisting being accomplished,
, preferably, before the strips are hardened to
lower portions l and 2, respectively, presenting render them resilient or, if hardened strips are

and lower portions I and 2. 'I'he ends of the said
strands of zig-zag wire are similarly bent to pro

posed to the U-` or V-shaped formation 3 and pro
30 Jecting between the upper and lower portions i
and 2 in substantially the same manner. The op
posed extremities of the said strip or strand of
wire are suitably joined or coupled with each
, other by means of coupling sleeves 5 as shown in
35 Fig. 3, or in any other suitable manner.
A plurality of strips of the type illustrated in
Fig. 2 and hereinabove described, are disposed in
parallel relation to each other as shown in Fig. 1
and may be spaced from each other to any suit
able or selected extent. Preferably, the portions
of the strips or strands which extend substantially
transverselyto the lengths of the upper and lower
portions I and 2 or to the length of the strips, are
disposed in substantial alignment with each other
45 in contiguous strips and, preferably, said strips
are coupled with each other by means of wire
helicals 6 which embrace said aligned lateral por
tions of said strips "occurring at intervals in the
length thereof. The number of said helicals 6
50 employed is selective and depends upon the judg
ment of the manufacturer and the purposes for
which the spring assembly is to be employed, it be
y ing obvious. of course, that other connecting
means of a resilient nature well known in the
55 art may be employed in place of the helicals 6
tions 3 and 4 of said strips as will be obvious.
The said upper and lower portions l and 2, or
one of -them, of said strips of zig-zag wire may be
slightly bowed if desired and thus provide slightly
convex surfaces opposed to the padding subse
quently supplied in the production of finished
cushions.
_
It will be apparent also that the strips dis
posed in the middle portion of the assembly shown
and which are subjected to the greatest degree
of load, may be bowed to a greater extent than
the side strips so that the completed spring as
sembly may present substantially and approxi
mately sphero-convex skeleton surfaces.

1. An all-wire spring assembly. for incorpora

supporting surfaces in said spaced relation to
each other, the respective strips of the series be 50
