, tab de?ning slots 2i spaced from each other a
distance corresponding to the length of a com
mon brick. Although the dimensions of these
slots may vary within certain limits, it is pref
erable that their lengths correspond to the ap
proximate depth of an ordinary brick and their
width correspond to that of an ordinary vertical
mortar Joint of a brick wall. Spaced above the
top edges of this row of slots 2| a distance cor
10 responding to the depth of a horizontal mortar
joint of a common brick wall are a plurality of
slots 22. These slots 22 are located so that the
longitudinal median line of each of these slots is
approximately coincident with the transverse
15 median line of the area therebelow and between
the slots 2i. These slots also need not be of exact
dimensions, but for the purposes of this inven
tion it is preferred that their width be substan
tially the same as that of the slots 2! and their
20 length be equal to that of a slot 2| plus the depth
of a horizontal mortar joint of a brick wall. The
simulating area. The purpose of this particular
design is so that when the strips are laid in the
customary manner side by side in any one course,
the quarter brick simulation of one course will
be immediately adjacent the three-quarter brick
CW
simulation in the same course of another strip
immediately adjacent thereto and together will
form a full brick simulation.
Moreover, when
the covering is laid in the ordinary manner of
overlapping courses with the slots 2i of an over-
lapping course appropriately staggered with re
spect to the slots 22 of a subjacent course, the
line of juncture between adjacent strips of the
lapped portion of the subjacent course will not
be in line with the slots of the overlying course, 15
but will be covered by the brick simulating areas
of the overlapping course.
These strips are laid in the customary man
ner to provide a brick wall simulating siding by

The next strip of that course is laid by posi

scribed. The total upper face of the strip, name
and locating it so that its left hand edge is closely
ly that face to be exposed, has a coating of as
adjacent to the right hand edge of the previously
phalt or similar bitumen thereon. Preferably applied strip and its upper and lower edges are
the asphalt coating is of predetermined and equal
40 thickness on those areas of the strip extending
from the butt edge thereof to the tops of the cut
outs 2i and from the/bottoms ofthe cut-outs 22
to a distance slightly below the tops of the cut
outs 22, corresponding to the depth of a hori
45 zontal mortar joint of a brick wall. The asphalt
coating onthe remaining area of the strip com
.prising the areas between the upper and lower
limits of the lower and upper coatings respec
tively and between‘ the upper edge of the strip
50 and the upper limit of the upper coating, may
also be of predetermined thickness and prefer
ably of less thickness than that of the other
coated areas. In order that the rectangular
areas having the coating of greater thickness
55 thereon and de?ned by the butt edge of the strip,~_
the longitudinal edges of'the slots, and the upper
' and lower limits of the thicker coatings may sim
ulate bricks, the coating on these rectangular
areas has partially embedded therein a layer of
60 relatively coarse mineral granules such as com
mlnuted slate, slag or the like of any desired
brick color. The remaining or thinner coating
layers adjacent thereto and of a color' contrast
ing with that of the surfacing material need not
66 be surfaced, but I prefer to surface these areas
with. talc, mica or other relatively ?ne grits of
mior and
contrasting with that of the
brick surfaced areas.
Moreover, in order that these strips may pro
vlde an e?lcient weatherproof covering simulat
ing a brick wall, the strips are of such length
that the respective end brick simulating areas
30 and 3| on each end of ‘the strips are respec
tively less than and preferably about one quarter
75 and three quarters the length of a full brick
in substantial alignment with the corresponding
limits of the previously laid shingle. At this stage, 40
as before, it is to be fastened to the supporting
structure by nails driven therethrough and. into
the supporting structure. Thus, the first course
may be completed by a repetition of these simple
operations.
After the ?rst course has been properly laid,
the next succeeding or overlapping course is ap~
plied. In order to provide an e?icient weather
proof covering closely simulating a brick wall
and so that the line of juncture between the ad:
jacent strips of a subjacent course shall not coin
cide with either a slot in or the line of juncture
between adjacent strips of a succeeding or over
lapping course the initial strip of the next suc
ceeding or overlapping course is preferably not a
full or normal length strip but comprises a
shorter strip having its end brick simulating areas
corresponding to those on a full or normal length
strip. This shorter strip is laid with its left hand
edge coinciding with the corner of the building 60
and with the left" hand edge of the ?rst full or
normal length strip in the previously laid course,
and its butt edge coinciding with the tops of the
cut-outs 22, in the subjacent course. A plurality
of nails are then driven therethrough at that
portion of the strip above the tops of the cut“
cuts 22, and into the supporting structure. As
before, a full strip is laid with its left hand edge
coinciding with the right hand edge of the pre
viously laid strip and with the upper and lower 70
edges of the full strip being in line with respective
limits of the previously laid shorter strip, and
a plurality of nails driven therethrough at any
appropriate place. The course may be completed
