This invention relates generally to cushions .and
refers more particularly to seat cushions of the
type wherein resiliency is secured by a series of
coil springs.

In accordance with conventional

tion to reduce the cost of manufacture, render
trated in -Figure 1. The bottom marginal frame
is equipped with a plurality of transversely ex
tending bars i3 and the lower convolutions I4 of
each coil spring are suitably rigidly secured to the
bars i3 between the latter. As stated, the con
struction brieily outlined above may be varied

and this construction should vnot be construed as

In accordance with this invention, the upper
ends of the coil springs l2 are covered'with a
composed of a plurality of separate strips having
the adjacent edges secured together with the
edge portion of one strip folded over the bottom
surface of the strip and secured to the latter

row of coil springs. Upon reference to Figures
2 to 4, inclusive, it will be noted that each strip
i6 is folded at one longitudinal edge to provide a

folded edge of each strip overlaps the adjacent
free edge portion i8 of the next adjacent strip in
the covering sheet through the adjacent edges
such a manner as to provide three thicknesses
of the strips cooperating to form this sheet.
In addition to the foregoing, the present in

of a relatively 'few simple parts capable of being
expediently assembled and providing an inex

The flaps l'l have a width approximating the
diameter of the upper convolutions 20 of the
coil springs and the convolutions 2€? of the coils
in each transverse row of springs l2 extend beu
tween the flaps I'l of each strip I5 and the under~
side of this strip. The flaps il are secured to the
strips lil by transverse `lines ofstitching 2l located
between adjacent convolutions 2li and forming
individual pockets 22 for the convolutions
The
pockets 22 thus formed are closed on three sides
and the upper convolution of each coil spring may
be readily inserted into each pocket 22 through
the remaining open side of the latter.
As a

the coil springs are secured in assembled rela
result, the upper ends of the coil springs are eff .

and the objectionable noise resulting from metal 50
to metal contact is eliminated.
In the present instance, the upper convolutions
20 of the coil springs are secured in their re
spective- pockets by means of hog rings 23. The
50 cushion may vary in design in accordance with
the specific specifications required. However, for
the purpose of illustration, the seat cushion is
shown in the several figures as having top and
bottom marginal frames le and lâ, respectively,
suitably reinforced to impart the required rigidity

tions 20 of the coil springs and are passed
through the three thicknesses of material in the
manner clearly shown in Figure 4. Thus, the
hog rings not only secure the upper ends of the
coil springs in their respective pockets 22, but
also assist the stitching I9 in securing the adja
cent longitudinal edges of the strips I6 together
to form the cover I5. By securing the upper ends
of the coil springs in the pockets 22 in the above
manner, the top surface of the cushion is main
tained substantially flat and a comfortable seat

results.
In Figure 5, I have shown the manner in which
the upper ends of the coil springs at the mar
15 ginal edges of the seat are secured in their
dividual pockets for the end convolutions of the
springs, and tie members extending through the
lapping edge portions of the strips and around
said end convolutions of the springs to secure the
latter in their respective pockets.
3. In a spring cushion, a plurality of coil springs
supported in spaced relation to each other and
arranged in rows, a strip of fabric extending over
one row of springs and having one edge folded
back upon the strip to form a ñap cooperating 10
with the inner side of the strip to substantially
receive therebetween an end convolution of each
spring in s_aid row, a line of stitching located
between adjacent springs in said row and se
curing the flaps to the outer portion of the strip 15
to form individual pockets for the end convo
lution of each of the springs in said row, a second
the top convolutions of the coil springs in the rstrip extending over the next adjacent row of
springs and having one edge lapping the folded
pockets 22 and are also extended around the
edge of the first strip providing three thicknesses 20

out that the coils 2U are effectively insulated tending through the three thicknesses of material
to secure the adjacent edges of the strips together,
from metallic contact with the frame by the ma
terial 26 at the ends of the pockets and by the and means for securing an end convolution of

From the foregoing, it will be noted that I have ing a tie member projecting through the three

wherein the upper convolutions of the coil springs pocket around the convolution of the spring.

are disposed in individual pockets formed by the
covering for the seat. It will also be apparent supported in spaced relation to each other, a 30

figure, suitable hog rings 25 are passed around

the cushion is maintained substantially flat. In
addition, it will be apparent that I have secured
the above advantages with a construction capable
40 of being inexpensively manufactured and readily
assembled.
What I claim as my invention is:

supported in spaced relation to each other, a
f covering sheet for the springs comprising a plu

50 the inner side of the strip and cooperating with
the inner side to receive the end- convolutions of
one series of springs therebetween, means secur

edge of the next adjacent strip to form a con
tinuous covering sheet, means securing the flaps
of each strip to said inner side to form individual

and means cooperating with the lapping portions
of said strips for securing an end convolution of
each spring in its respective pocket.
