stood by reference to the following specification
To provide for adequate support of inner spring
and accompanying drawing, wherein there is and other mattresses, a top structure embodying
illustrated a. bed spring embodying a selected
f form of the invention.
In the drawing:
Fig. 1 is a plan; and
Figs. 2 and 3 are sections on the lines 2-2 and
3--3 respectively of Fig. 1.
The bed spring illustrated in the drawing in
cludes a top border frame 5 preferably made of
angle iron, a bottom border frame 6 also prefer
ably made of angle iron, spring supports such as
indicated at 'I and axially vertical coil springs the
L outermost of which are designated 8 and the in
termediate of which are designated 9.
4The lower border frame 6 is preferably ar
ranged with its vertical flange depending from
the inner edge of the horizontal flange and the
2 spring supports l are suitably secured to the
vertical flange of the lower border frame by rivet
ing or otherwise as indicated.
The supports ‘I
preferably extend transversely of the bed- spring
and the coil springs 8 and 9 have their lower
40 ends seated on and suitably tied to the respective
supports.
As shown, especially in Fig.y l, ythe springs 8
thin, flexible, metallic straps is provided.
In this instance, the top structure includes a
plurality of relatively short straps each of which
is designated I4, said straps being arranged in
rows overlying diagonally extending spring rows.
Preferably the straps are each of such length that
they extend approximately from center to center
of the springs in each row. Hence the straps are
arranged in rows overlying spring rows and, as
clearly illustrated, the short straps are arranged
substantially in longitudinal alignment. The
rows of spring straps also intersect one another in
accordance with the similar arrangement of the
spring rows and the arrangement is preferably
such that the intersection of rows of straps is
located approximately centrally over the coil
springs. It is also preferably such that there is
an intersection over each of the coil springs, es
pecially in reference to they inner springs 9.
Where the strap rows intersect over springs,
the adjacent strap ends are preferably pivotally
connected together. Such connection is in this 40
instance effected through the agency of a metal
which extend under the horizontal ñang‘e of the
upper border frame 5, and rivets designated II
which extend through the border frame and
through said spring loops serve to securely an
lic plate I5 which has portions overlying each of
the adjacent strap ends and pivoted thereto as
indicated at I6. As clearly shown in Fig. 3, the
pivot connection I6 between the plate and each
strap I4 is formed by punching the metal of the
plate I5 downwardly through an appropriate
>opening I‘I provided in the strap I4 and swaging
the punched down metal outwardly as indicated
at I8 to form an eyelet connection between the
respective plate portions and the strap ends.
-At the periphery of the top strap structure, it
is connected to the border frame by means of
resilient helical coil spring connectors E9. At

It will be seen that the described top strap con
struction is not only îlexible in a vertical direc
tion so as to follow the compression of the axially
vertical coil springs, but that the rows of straps
are flexible laterally owing to the pivoted con
nection of the respective short strap lengths
which form the rows. By reason »of the lateral
?lexibility, said strap rows may flex in localized
areas when required without transmitting lateral
movement over the entire length of the strap
rows. This is an advantage »in that it tends to
reduce side sway and to confine it to localized
zones where it may be incident to» compression
of the vertical springs and sidewise movement
imparted thereto. The straps I4 provide ade
quate supporting area for a mattress to prevent
the same from sagging between the straps and
such supporting area is of course augmented by
the connecting helicals I2 and I3 and by the
top coils of the vertical springs 8 and 9. In one
embodiment, the straps may be about % of an
inch in width and in theY neighborhood of nine
inches in length. Of courseA the length will be
55 dependent upon the spacing of the springs in
the rows, where it is desired that pivoted con
nections should be effected over each spring and
. upon other considerations incident to the par
ticular 'construction ofthe bed spring in which
60 the top structure is incorporated.

anchored at a few places to top coils of a few of
the axially vertical springs. Such anchoring may
