This invention relates to new and. useful im

and has more particular reference to so-called in

Still further the invention proposes an 1111-,

materials.
I am aware of the fact that brick dust has been
used in connection with concrete to construct ar
ti?cial bricks. I am also aware that brick dust
has been used as a coloring material for plastic
materials from which various articles are molded.
However, the advantages gained by using brick
dust in an interior plaster or plaster board has
never been discovered before.
It is another object of this invention to use
the largest percentage possible of brick dust in a
plaster or plaster board, commensurate with the
production of a good interior plaster and plaster
board.
I believe that an interior plaster is generally
characterized by the use of hydrated lime, and
the dominating feature of my invention is the
use of brick dust with such plaster.
The improved plaster, in accordance with this
invention, may be used for all purposes for which
interior plasters ‘are now being used.

The plaster boards are made by mixing the
materials and working them in the usual ways.
While I have described the preferred embodi
ments of my invention, it is to be understood that
I do not limit myself to the precise formulas
herein‘ disclosed, and the right is reserved to all
changes and modi?cations coming within the
scope of the invention as defined in the append;
ed claim.
Having thus described my invention, what I
claim as new and desire to secure by United
States Letters Patent is:
An interior wall plaster, consisting of, a mix
ture of a Portland cement base, 100 lbs.; hydrated
lime, 10 lbs. ; brick dust, 20 lbs. ; sand and marble
dust, 10 lbs.; and water, 10 to 15 gals.
