adjusted so that a considerable part of the coat- 25

mechanism is arranged to scrape off relatively
wide areas 8" in order to give the desired ulti

If desired, in making the imitation brick de
sign illustrated in Figures 2, 3, 4 and 5, a mat
or tapestry brick effect can be obtained by the
provision of a series of hoppers I 0 each carry 15
ing a different colored grit. By the provision of
suitable valves in these hoppers the ?ow of grit
from onejhopper can be so timed that it will '
occur only during an interval necessary to distribute grit of the desired color to an individual 20
brick-simulating space.
The discharge from
the other hoppers is cut off during this interval and is thereafter allowed to occur, one by one,‘
verse cuts 22 are thereafter made in order to

carrying the other colored grit is shut off. In
