9 Claims. (Cl. 20--1)
This invention relates t0 »framework formed of
relatively light planks of wood or other material,
and the primary object of the invention is to pro
vide frameworks of this character of larger size
and greater strength than have heretofore been
available, by associating the planks in a novel
manner under tension.
`
`
Other important objects and advantages of the
invention will be apparent in the following de
scription and the accompanying drawings, where
in for purposes of illustration only, preferred em
bodiments of the invention are set forth.
In the drawings:

the planks I0 and II stresses these planks and
hence the entire framework, and thereby the
framework’has rigidity and resistance to distor
