l Claim.
This invention appertains to building blocks
and tiles formed from cementitious or similar
material and more particularly to so-called “cin
der” blocks.
One of the primary objects of my invention is
to provide a block or tile which can be readily
broken by the builder on the job into various
sizes of complete blocks or tiles, so that a desired
of block or tile will be had to lit a particular
apart relative to one another and to the end walls
'l and 8, for a purpose which will be later set forth.
If desired, the lower end of the block or tile
can be closed by a bottom Wall to reinforce the
block or tile, and the bottom wall I2 is provided
with openings I3. All of the Walls are so shaped
as to facilitate the removal of the block from
the mold. It is tol be noted, however, that the
space between the pairs oi walls is left open from
the top of the block to the bottom.
Another salient object of my invention is to

A further important object of my invention is
The block is also adapted to be readily broken
to provide a block or tile, which is so constructed longitudinally so as to form building slabs and
that the same can be readily broken longitudinal
