1 Claim.
(Cl. 72-37)
My invention relates to bricks and is particu
larly directed to corner brick used with facing
brick in building construction and the like.
This invention is especially intended for use
5 with face brick of the type shovm in my copend
ing application Serial No. 550,336 ?led July 13,
The extended commercial adoption and use of
face brick in place of the old full size brick for
10 building purposes created a problem in connec
tion with the use of brick for corners which would
conform to, in point of space occupied, and ap
pearance, the face brick used in the flat wall sur
faces. To use a full size brick at the corners of
15 a structure where facing brick was used for the
wall surfaces in order to secure the proper full
width appearance at such corners, meant the pro
jection inwardly from the rear surface of the
corner of approximately half of the width of
20 the brick. This was objectionable because fre
quently face brick are used to cover over an old
structure, perhaps of wood construction, and the
shown in Figure 3, namely, in the position and
condition in which it passes through the die in
strip form.
Figure 6 is a detail perspective view illustrating
the use of corner face brick under actual con-
ditions of construction.
The reference character I refers to a suitable
container for the plastic brick material supplied
by any suitable apparatus for mixing and forcing
the plastic material therethrough. One end of m
the container I is ?anged as at 2 and removably
secured to the ?ange as by the bolts 3 is the ?ange
4 of an expressing die 5 provided at its front end
with a ?anged plate 6. The die 5 is provided with
a passage 1 therethrough which at the plate 6 1
de?nes the approximate size and shape of the
brick to be formed, by the opening 8. This pas
sage ‘! is wider at the rear end of the die 5, the
side walls of the opening diverging rearwardly as
at 9 so that at the point of communication with
the discharge end of the receptacle 1, such pas
sage is relatively large and then tapers down to
the size of the opening 8.

To meet this problem I have provided a corner passage 1 therethrough and adjacent the point of

My invention embodies not only the corner
face brick itself but the method and apparatus
for making the same.
Various objects and advantages in details will
be apparent as the description proceeds, refer

panying drawing forming a part of this applica
tion and wherein like reference numerals in

A ribbon of plastic brick material I3 is forced .5
by any suitable means through the die 5 and out
wardly through the opening 8 in the front end
thereof on to a moving belt 14 preferably of an
endless character, trained over a pulley wheel 15

of the ends of the opening 8 whereby to trim off
the extreme ends of the ribbon of plastic mate

and on to the conveyor belt 14. These trimming
wires perform the twofold function of trimming
the ends of the plastic material to exact size and
also of providing the sides of the plastic material

mat finish desirable in bricks of this type.
