13 Claims.
This invention relates to a novel and improved
vcomposition‘material, and particularly pertains
to compressible and elastic material or material
which will expand upon release of a compressing
Cl
force.
,
The invention, generally described, comprises
an' envelope or casing which is ?exible and yield=
able, but su?iciently board-like to be self-sus

taining and retain its shape for handling and
transporting. Within this envelop or casing,
there is contained a strip of compressible and

solid rubber, yet being inherently compressible
and elastic to a degree approximating that of
sponge rubber. To give the strip a maximum de
gree of rigidity, numerous sponge rubber layers
are inserted and separated from each other by Ul
walls 4 integrally formed with the casing.
If the planking‘ be used for flooring, one face
may advantageously be coated with a paint layer
5 of any desired color.
The composite strip may be formed by associ
ating the inserted layers and easing togetherin

Referring to the drawing, numeral i designates
a ?oor planking or expansion Joint strip com
prising an envelope or casing 2 of rubber or the
like, having one or more sponged rubber layers
50 3 inserted therein.
The sponge layers contain
myriads of‘ cells ?lled with air which becomes en
. trapped within the casing upon insertion of the
layers-to make them sluggishly yieldable. As a
result, a more or less solid character is provided
55 throughout the strip, giving it the appearance of
There is disclosed in Figure 6 a rail ?ller l0, con
toured to ?ll the cavity of a rail H, which com
prises an envelope i2 having inserted strips 13
of sponge rubber. In Figure '7 a packing strip
comprises a. single core it of sponge rubber ma
terial enveloped with a rubber casing H5. The 30
beading it (Fig. 8) is of the same general struc
ture as the packing in (Fig. 'l) and di?ers only as
to the contour or shape in which it is molded.
_ Numeral i1 designates a chair seat (Fig. 9) which
may be of a construction as above described. 35
While I have shown and described several em
bodiments of- my invention, it will be understood
that these are for the purpose of illustration'and
not as a limitation, for various changes in con
struction may be made without departing from 40
the spirit of the invention.
