This feature makes it possible to lay the shingles

in a favorable competitive position with looking
shingles of the same general type which cannot
be so laid. Since the cost‘ of applying shingles is

roof, the design of the locking device of the pres

Hence, lia
bility of damage to the shingles and roof during
laying is minimized and the speed with which a
workman may lay the shingles is greatly in
creased. The short slits 23, 24 permit the inner
corners of locking slits 20, 2| to snugly engage the
inner corners of locking notches 33, 34 of under
cisions of the shingle to be laid in locking en
gagement with the notches of a pair of like un
derlying elements without buckling the portion
lying shingles without tearing the shingle bodies.
If the shingles A and B of the underlying course
are in proper alignment, it will be seen that when
the walls of slits 24 and 23 are brought snugly
20 against the apices of notches 33 and 34 respec
tively, the shingle C will be in its properly aligned
. position in the next overlying course.
In Fig. 4 there is shown a cutting diagram il
lustrating how the shingles may be out without
waste from a roo?ng sheet. As hereinabove
pointed out, the transverse edges of the shingles
may advantageously be complemental when they
shingles are reversed and laid end for end. In
cutting the shingles a saturated coated and sur
30 faced roo?ng base may be divided into two or
more strips by longitudinal cuts 31 and the strips
severed into individual shingles by broken,
staggered, transverse cuts 39. The slits 20, 2|,

operation by appropriately disposed knives on
the cutting cylinder or other cutting mechanism
employed. It will be noted that adjacent shingles

Accordingly, it will be seen that we have pro
vided a self-aligning shingle which may be rapidly
and easily laid with other similar shingles in wide
spaced, securely interlocked relation without dam

shingle body. The’ shingles may be out without
substantial waste and hence afford an economical
