2 Claims.
(Cl. 10S-’1)
This invention relates to roofing shingles and
more particularly to shingles made from composi
. tion roofing material.
An object of the invention is to provide a
roofing shingle oi simple construction which can
be laid in successive courses to give the appear
ance of shingles laid according to what,is known
as the American method, with the adjacent
shingles of each course interlockíngly interñtted
10 with another, and so secured in place as to in
sure against any tendency of the exposed portions
of the shingles being lifted under the action of
wind.
.
-
Another object is'toV provide a shingle of the
type described in which the interlockingly inter
ñtting portions are formed >in such a way as to
permit the shingles to be laid with the butt
edges of the shingles of each course extending in
substantially continuous unbroken lines parallel
to the cave line of the roof.
Another object is to provide a shingle, as set`
forth, which can be cut from a sheet without
20
waste and be laid up very rapidly without requir
ing special skill on the part of the workman to
interñt the adjacent shingles properly.
2
Still another object is to provide a shingle re
quiring a minimum quantity of material to cover
a. given area of surface consistent with adequate
protection, and to proportion the shingles and
30 their interlocking parts so as to permit covering
a given area with fewer shingles than ordinarily
the shingles. One of the lower corners of the
shingle is cut away "'töprovide a right angular
notch or recess I I, one edge I2 of which is paral
lel to the upper edge 'I3 and butt-edge I4 of the
shingle, the other edge I5 of the recess being
parallel to the lateral edges I6, I1 of the shingle.
The edge I5 of the notch is spaced inwardly of
the edge I6 a distance corresponding to the
amount of overlap between adjacent shingles in
each course. Preferably, the edge I5 of the notch 10
is one-half the length of the edge I2. Atl the
end of the shingle opposite the notch I l, there is
a rectangular tab or projection I8, extending
laterally beyond the edge I1 of the shingle. This
tab has an upper edge I9, equal in length to the
edge I2 of the notch> I i, and extending at a right
angle to the side edges of the shingle and in
alignment with the edge I2 of the notch. The
terminal edge 20 of the tab extends at a right
angle to the edge I9. and is parallel with the
edge I5 of the notch and the side edges I6, I'l “
of the shingle. Since the opposite ends of the
shingle are thus mutually complemental, the
shingles may be cutl from a sheet of prepared
rooñng without waste, except for a negligible
quantity at the end of the sheet.
'
In order to derive the maximum economy of
which shingles constructed as described, are sus
ceptible, I prefer that the major horizontal axis
of the shingle, namely, the distance between the
edges I6 and I'I, be about one and one-half times
the distance between the upper and lower edges of
the shingle, so that when laid upon a roof in ‘suc
cessive courses, as shown in Figure l, each shingle
may safely be exposed for a distance as much as 35
two-thirds the height of the shingle. The ad
Figure 2 is a cross-section 'through several of - jacent shingles of each course will be interfltted
the adjacent shingles in a course, taken along in such manner that the projection I8 of each
required.
In the drawing,
Figure 1 is a plan View showing several courses
35 of the shingles as they appear when laid,
' line 2-2 of Figure 1,
Figure 3 is a. cross-section taken along linev
40 3--3 Of Figure 1,
Figure 4 is a view in perspective of one of the
shingles.
_The shingles constructed according to the in
45
vention are preferably made from prepared as-phalt roofing consisting of a felted fibrous base.
impregnated with water-resistant material, such
as asphalt, and coated on one or both of its sur
faces with blown asphalt or equivalent weather
proof substance in which crushed slate or other
50 comminuted wear-resistant mineral may be par
tially embedded to provide a iinìsh surface as
customary in this type of roofing.
According to -the invention the shingles are
of rectangular shape with the major axis thereof
extending in the direction of the butt-edge of
55
shingle, extends beneath the edge I5 of the ad
jacent shingle, the latter being overlaid by the
first named shingle, so that the edge Il of each
shingle is in substantially vertical alignment
with the edge I5 of its adjacent shingle. In
order to secure the shingles properly, a nail or
other fastening device is driven through each 45
shingle, at a point indicated at 2|, located ap
proximately at the center of the tab or projection
I8, and another nail is driven through the
shingle near Vthe upper edge thereof and adja
cent the edge Il at a point indicated by the
numeral 22. With two nails thus driven through
a shingle, every shingle will be penetrated by
four nails, two being those driven through the
1shingle at the points mentioned, another being
the nail driven through the point corresponding 55
2
2,117,624
to the point 22 of the adjacent shingle in the
same course, and the fourth nail being the nail
driven through the adjacent shingle in the over
lying course at the point corresponding to 2I.
In this way, the shingles are held firmly in place,
each of the shingles being nailed adjacent one
end of the butt edge thereof, while the other end
of butt edge is held securely in a flat position
by the interlocking arrangement with its adja
upper horizontal edge of the notch and of the flap
of each shingle being parallel to the butt end of
the shingle, the flap of each shingle being integral
with the body over the full depth of the ñap, one
of said shingles having a nail through said flap,
and the next horizontally adjacent shingle having
permit each shingle to accommodate itself to
the expansion and contraction of the roof boards
without buckling.
its vertical edge above said notch inserted under
the vertical edge of the ñrst shingle down to said
ñap and having the notch in the second shingle
placed around the upper juncture of the flap with
the ñrst shingle to permit -the butt end of the
second shingle to be aligned in, the same line
including the butt end of the ñrst shingle, and
The shingles, as thus laid, present an attractive
appearance of what is known as the American
shingle, and succeeding >shingles similarly assem
cent shingle in the same course in a manner to
method of laying with the exposed butt edges of
each course in continuous unbroken lines.
In order to facilitate the work of laying the
shingles, I prefer to form a notch 24 in the edge
I‘I of each shingle, to indicate to the Workman
the extent of overlap of successive courses, and
a similar notch 25 in the upper edge I3 of each
shingle in vertical alignment with the edge I5 of
the notch II, so as to ensure every shingle being
laid true.
To illustrate specifically an economical propor
tioning of a shingle constructed according to the
invention, the shingles may be eighteen inches
long, between edges I6 and I'I and twelve inches
30 in height, with the projection I8 measuring four
inches in length and two inches in height. With
shingles dimensioned as indicated, each course
may be exposed eight inches with ample security
against leakage of the roof.
35
It will be understood, of course, that the shingle
elements constructed according to the invention
may be used for covering the side wall of build
ings as well as for roof surfaces.
I claim as my invention:
1. A roof comprising a plurality of composition
40
shingles, each of said shingles being substantially
rectangular in shape having a nail flap extending
laterally from the lower corner at one side of the
shingle, and a notch cut-out of the lower corner
at the opposite side of the shingle, the notch and
flap each having a straight horizontal upper edge
extending the full length thereof and the said
having a. nail through the flap of the second
bled one with the other to form a continuous row
across the roof, and a second row of shinglesl
overlapping the ñrst row from above.
2. A roof comprising a plurality of composition
shingles, each of said shingles being substantially
rectangular in shape having a nail flap extending 20
laterally from the lowercorner at one side of the
shingle, and having a notch cut-out of the lower
corner at the opposite side of the shingle, the
notch and ñap each having a straight horizontal 25
upper edge extending the full length thereof and
the said upper horizontal edge of the notch and
of the flap of each shingle being in longitudinal
alignment and substantially parallel to the butt
end of the shingle, the flap of each shingle being 30
integral with the body over the full depth of the
flap,.one of said shingles having a nail through
said flap, and the next horizontally adjacent
shingle having its vertical edge above said notch
inserted under the vertical edge of the ñrst
shingle down to said ilap and having the notch
in the second shingle placed around the upper
juncture of the flap with the ñrst shingle to per
mit the butt end of the second shingle to be
aligned in the same line including the butt end
of the first shingle, and having a nail through 40
the flap of the second shingle, and succeeding
shingles similarly assembled one with the other
to form a continuous row across the roof, and
a second row of shingles overlapping the first
row from above.
