This invention relates to a method of applying
granular surfacing material to a face of a sheet
of roo?ng material or its equivalent.
_
it is an object of the invention to provide
means for facilitating the manufacture of roo?ng
elements such as strip shingles or individual shin
gles having areas of distinctive colors on the por
tion which is to be exposed to view when the ele
ment is laid with others in overlapping relation

It is an object of the present
invention to utilize in a convenient and econom
ical manner the commingled vari-colored granu
lar matter recovered from the surface of a sheet
of roo?ng material or the like. According to the
invention, this object may be attained by de
ployment of the surplus granular material which
positing on predetermined areas of a sheet of
sticky roo?ng grits of different colors for different
areas comprising portions of the face of the sheet,
recovering the excess non-adherent grit from
these areas and depositing the recovered grit of

In manufacturing roo?ng units such as strip previously covered.
For the protection of the outer face of a roo?ng
shingles, it is customary to saturate a sheet of
unit, such as a strip shingle or individual shingle, 15
lili roo?ng felt with asphalt of suitable character
istics. This saturated sheet is coated with an it is desirable that the entire outer face, i. e. the
adhesive waterproof material such as blown or face which is uppermost when the element lies
oxidized asphalt. While this coating layer is on a roof, be entirely covered with grit or equiva
lent granular matter. However, as far as color
stlclry, it is surfaced by the application of granu
lar material such as crushed slate, sufficient of effects are concerned, the only portion of the
the granular material being partially embedded outer faceof the roo?ng unit which matters is
that portion which is exposed to view when the
in the sticlry asphaltic layer to form a practical
ly continuous protective surface layer. In order roo?ng element is laid with others in overlapping
to ensure the formation of such a surface layer,
25 it is necessary to deposit on the coated face of
the sheet an excess amount of the granular ma
terial. Where the surfacing material used on the
sheet is of a single color, the excess grit which
falls to adhere to the asphaltic layer is subse
w uuently recovered and re-deposited upon the
sheet so that there is substantially no loss of grit.
Owing to a great demand for roofs of variegated
colors, considerable quantities of roo?ng ele
ments, such as strip shingles, are produced hav
lug on the exposed portions thereof areas of
different distinctive colors, so that, when such
roofing elements are laid upon a roof, the roof as
a whole presents a vari-colored appearance. It
is evident that, in order to produce areas of dif
Alli ferent distinctive colors on a roo?ng unit, it is
necessary to apply separately to each area gran
ular matter having the particular color desired
for such area. This can be done with little diffi
culty, but, inasmuch as there must be deposited
45 upon each such area more granular material
than will adhere to the sticky face of the area,
the problem of the ultimate disposition of the
excess non-adhering granular matter from dif
ferently colored areas arranged longitudinally of
50 the sheet has been a serious one since it is im
practical to recover separately from each colored
area the granular matter of the several colors.
That is, in recovering loose grit from the surface
of a sheet thus treated, the commingling of grits
55 of the various colors cannot, as a practical mat
courses on a roof.
Hence, according to the pres
ent invention, these portions of each roo?ng ele
ment may be treated differently from the portions
of the element which are covered and hidden
from view when laid. Thus the exposed portions
of the roo?ng element are surfaced in such a way
as to provide areas of distinctive colors, the com 30
rningled excess grit being employed to surface
the covered or hidden areas of the roo?ng unit
where the matter of color is of no importance.
Furthermore, if desired, some of the mixed grit
may be used on areas to be exposed to provide an 35
additional color for such areas.
For a more complete understanding of the in
vention, reference may be had to the detailed
description thereof which follows and to the dis

As indicated on the drawing, valves or equiva

spouts.
For convenience, the valves in the spouts
of each series are mounted on a common shaft '
40 so as to operate in unison. Each shaft 40 may
be rocked by suitable mechanism such as a lever
arm 4| which extends radially from the shaft 40
and is connected by a rod 42 to a cam follower 43
riding on a cam 44, there being a separate cam
for each of the shafts 40. The cams 44 may be
mounted on a common shaft 45 which is rotated

on the roof. 'Thus, if the sheet ID is to be cut
into multi~tab strip shingles of convenient shape,v
suitable slots E35 may be cut across each band 25
to form cut-outs in the finished strip shingle
which will define the shingle-simulating tabs
along the weather edge of the strip shingle. The
operation of the spouts 20, 2| and 22 can be
synchronized with the operation of the slot
cutting mechanism in such a manner that the
slots will coincide with the color boundaries be
tween successive color areas in each of the bands
25. In such case each tab of the strip shingle
will present a single solid color area. On the
other hand, the color areas may be formed with
out regard to the location of the slots which either
have been or are to be cut in the sheet, in which
case the resulting strip shingle may have some
such appearance as that indicated in Figure 5.
After the slotting operation, the sheet In may
be longitudinally slit, some of the slits 66 being
cut so as to intersect the rows of slots 65, other
in the corresponding hoppers to be deposited in
slits 6'! being cut on the medianlines of the bands
50 between successive bands 25. The strip shin
gles may then be severed from the sheet as by
transverse cuts 68. It is evident that the strip
shingles thus cut from the sheet will be substan
tially as illustrated in Figure 5, the exposed por
separate areas on the moving sheet, the areas of
tion of the strip shlngle having areas. of distinc
grit, formed by spouts which are alined in the
direction of movement of the sheet, being con
tiguous so as to form a. continuous grit band 25
on the surface of the sheet, as indicated in Figure
4. Thus each band 25 is composed of successive
tive colors thereon, the upper or covered portion
‘H being surfaced with grit in which the colors
are commingled. The particular shape of roo?ng
element illustrated in Figures 4 and 5 is by way
of illustration only, it being evident that the
contiguous areas of different colors, the several
