M invention relates to roofing, anld more specifically to an improvement in that type of roofing in which a plurality of exible pieces of roofing are.v interlocked with4 each other as they are laid.

Among the objects and advantages of the invention'may be enumerated an extensionL of the iield `of `use of rooting elements aci cording to my prior Patent No. 1,469,041=

lo September 23, 1923. f l,

In the accompanying drawings,

Figure 1 is a plan diagram of a strip of rooiing material indicating how it may be cut into shingles according to the invention 1: without any waste; i

i Figure 2 is a diagram indicating the laying of such shinglesto form a complete roof covering; and

Figure 3 is a perspective view of a single 'l0 shingle. f

In the embodiment -of the inventionaselected for illustration, I have departed from the relatively exact keystone shape of my prior patent to the extent of providing verl5 tical sides at 10 for a short distance at the lower portion of the shingle, and.y vertical sides at 12 for a short distance at the upper end of the shingle.l The intervening portion has to slope outwardl at 14 at a somewhat steeper angle than t at of the shingle considered as a whole, to compensatev for the use of the vertical portions 10 and 12.

At the bottom corners of the shingle, I provide locking tabs 16.l The provision of these tabs necessitates the formation of notches at 18 at the upper corners of the shingle.

At the bottom of the iaring central portion, I provide short shoulders 20, and the symmetry of the shingle requires the pres- 4o ence of corresponding shoulders 22- at the v top of the` flaring portion. In laying a complete roof covering made up of shingles accordingto the invention, the vertical por,-y

tions 12 of adjacent shingles in the same course are positioned in abutment as indicated at 24 in'Figure 2. `The tabs 16 of the shingles in the next course are ,then hooked under the shoulders 20 in the course already laid. The shingles in the thirdv course are then placed vertically above those inthe rst course, being interlocked with the shingles in the second course in precisely the same way. In the finished roof the exposed area of leach shingle' is a perfect rectangle,

as indicated by the dotted line 26 in Figure vertical space between said tabs andthe adp jacent shoulders determining the vertical 3.' By suitably proportioning the vertical` distance between the locking tabs 16 and the -shoulders'20, the complete roof covering may j be laid so that no'portion of the roof is protected by less than two thicknesses of material.

/ Witiout Ifurther elaboration, the foregoing will so full explain the gist of my 1nvention that ot ers may, by applying current knowledge, readily adapt the same for use -lunder variousv conditions of service. Moreover, it is not indispensable that all the features of the invention be employed lin conjunction, as they may advantageously. be embodied in various combinations and subcombinations.

What I claim is 1. A shingle having the genera'l shape of a keystone; andvhaving an upper portion with short vertical side edges, and a lower portion with short vertical slde edges; the middle portion between having diagonal side edges flared more than the taper of the -shingle as a whole, to compensate for the vertical portions; the contour of t-he shingle side above the center line being a reversed duplicate of that below, whereby the shingles can be cut from a continuous strip without any waste; notches in the extreme upper corners of the shingle and locking tabs at the extreme rlower corners, said notches leaving the necessary material to form said tabs; and horizontal shoulders joining said flared portion to said vertical portions; the

spacing between'successive rows of shin les on the completed roof, and being such t at no area of the finished roof will be covered by less than two thicknesses of material. 95 2. A shingle having the general shape of a keystone; and havmg an upper portion with short vertical side edges, and a lower portion with short vertical side edges; the middle portion between having diagonal sidel edges flared more than the taper of the shin le as a whole, to' compensate for the vertical portions; the contour of the shingle vside above the center line being a reversed duplicate of that below, whereby the shingles can be cut from a continuous strip without any waste; notches in the extreme upper corners of the 'shingle and locking tabs at the extreme lower corners, said notches leaving the' necessary material to no form said tabs; and horizontal: shoulders joining said flared portion to said vertical portions; the vertical ace between said tabs and the adjacent s oulders belng approximately one-third the height oi theeng tire shin le.

a keystone; and havmg an upper` portion with vertical side edges, and a lower portion with vertical side edges; the middle ortion between having dlagonal side e ges flared more than the taper of the shingle as a'whole, to compensate for the vertical portions; the contour of the shin le side above the center line being af reverse duplicate of that below, whereby the shingles can be cut from a continuous strip without any'waste; notches in the extreme u per corners of the shingle and locking ta s at the extreme lower corners, said notches leaving the necessary material to form said tabs;-

and horizontal shoulders joining said ared portion to said vertical portions; the vertical space between said tabs and the adjacent shoulders determining the verticlal spacing between successive rows o shingles on the completed root, and being substan- 3. As ingle having theggeneral shape of.

Kwhole, to compensate for the vertlcal tiallrt7 one-third of `a distance equal to the vertlcal dimension of the shingle minus the vertical dimension of said notches.

4.
