Theinvention relates to the type of spring as
semblies for upholstery, wherein each of the com
ponent springs is maintainedout of contact. with
the next adjacent spring or springs by interpos
ing fabric walls between contiguous ‘springs and
wherein said fabric walls cooperate with top and
bottom walls, to which they are secured,‘ to pro
vide rows of cells, each vof which may besaid
to be individual as to eachspring.
.Spring assemblies of the type referredtoare

The object of the present invention is to pro
the terminal coils of contiguous. springs of: the;
vide means which will act to prevent thecom
assembly, thus to avoid. havingthe: said“ springs
ponent springs of a springassembly of'the types
mentioned from crowding together and: becom
ing overlapped under the in?uence of lateral pres
sure exerted against the ends of thepspring as
sembly as invcrowding the same into a cushion
cover, or the like, by means of a conventional
mattress stu?ing machine.
A further object, of the invention is to proe
vide means for the purpose-set forth which‘ are
flat and very resilient and will overlap‘ the ter
minal coils of contiguous rows of springsof an
30 assembly for affording additionalv support for the
padding disposed between the cushion cover and
the top and bottom surfaces of the assembly.
A suitable embodiment of the invention is illus-,
trated in the accompanying drawing. wherein

cased spring assembly equipped with devices made
in accordance with the present invention.

device of the present invention secured in place

Fig. 3 is a view similar to Fig. 2 showing the
device of my invention secured in place by means
of hog-nose rings or equivalent devices.
In the instance illustrated, the spring assem
45 bly I is substantially of the type illustrated in
the L. A. Suekoff Patent No. 1,411,227, wherein a
casing comprising top, bottom and peripheral
walls, is equipped with partition walls extending
laterally and longitudinally of the casing and
which are secured to said top and bottom walls
by means of stitch chains 2 and 3, respectively.
The casing is thus equipped with individual cells
into which the springs 4 are introduced as par
ticularly illustrated and described in said letters

come‘noticeableto the occupant of va-seat cush-~ 20
ion containing the spring assembly; The said"
wider: portions of the strips 5lserveralso to afford‘
a?rm support for padding and relieve the fabric
top walls’ of, ,the. casings of some of the stress
due to theirasupport of said padding and load
upon the latter.
The lengthof each strip 515' substantially:
equal toIthe length'of a» row of~springs14 of the:
assembly; less one 'of- they springs of said row.
Thus, in the'yinstance illustrated, the springs:
41 are arranged inlp‘arallel rows' and each rowv
contains: six- of said'lsprings.disposed-practical;
ly side by side. _ In theinstance illustrated,- there-‘,
fore, the length of each strip 5\will be substan-tially equal to ?ve times the diameter-of one of ,
the-componentsprings of theassembly and will
overlaplthe: terminal springs of the two: con
tiguous rows at the points at which the springs
of said rows are most closely contiguous to-each
other. Between their terminals said strips 5 will gs
overlap the remaining springs of said two rows
Preferably, only one of said strips 5 is used
for each two rows of springs of the assembly.
In the instance illustrated, there are six rows of
springs 4 and, therefore, three of said strips 5 45
are shown to be mounted upon the assembly. 7
Also, preferably, as shown in Fig. 2,’ the ter
minal ends of each of the strips 5 are secured to
the terminal springs of the two rows of the
latter overlapped by said strip by means of the
hog nose rings 6 or any other suitable means.
Between their ends" said strips 5 are secured, pref
erably, to each pair of opposed springs of the
contiguous rows thereof overlapped by said strip 55
5 by means of stitching ‘I which engages one of
the strips 5 at a point substantially midway be
tween its side edges and at a point where a
lateral portion of the strip 5 overlaps or rests
upon the most closely contiguous opposed por
tions of aypair of springs, as at the point 8
where the stitch cord is knotted to said strip 5
and the portions of the springs next adjacent
thereto. From said point 8 the stitching is passed
10 or looped consecutively about the succeeding
pairs of springs and the portions of the strip
lying nearest adjacent thereto, as indicated at the
several points 9, said cord being‘then passed over
to the next succeeding strip 5 and attached simi
15 larly to the succeeding points 9 in the opposite
springs at points in the latter contiguous to said
ring formation successively to points therein
overlying points in the terminals of pairs of con
?ned springs, around the latter and said stay
formation, thence to the other terminal ring for
mation, through and about the latter and ter
minals of a pair of springs contiguous to said
last-named ring formation, thence across the
space between said last-named ring formation
of one stay formation to the nearest adjacent 10
ring formation of the next adjacent stay forma
tion and thence successively attaching said second
stay formation to said fabric and con?ned springs
as in the ?rst-named stay formation, said stitch-v
ing being continued as above set forth to ter 15
direction from the stitching of the ?rst-men- ' minate in the last in line of the ring formations
