Patented Feb. 21 1933 UNITED STATES PATENT OFFICE NORMAN P. HARSHBERGER, OF CHICAGO, ILLINOIS, ASSIGNOR TO BAIELITE BUILDING PRODUCTS COMPANY, INC., OF NEW YORK, N. Y., A CORPORATION OF DELAWARE STRIP OF ROOFING MATERIAL Application filed may 12,

so as to provide a pleasing appearance for the roof. One object of the invention is to Y provide suitable means for locking down the exposed portions of the shingles and for looking the adjacent shingles together. Another ob ect is to provide for variegated figures on the roof when the shingles are laid and to accomplish this without inconvenience when laying the shingles.

Of the accompanying drawings, Fig. 1 is a plan view of shingles which embody the features of my invention, showing how the shingles may be cut from sheets of shingle material; Fig. 2 is a plan view of one of the strip shingles; Fig. 3 is a plan view of a number of the shingles as they appear when assembled on the roof; Figs. 4,5 and 6 are corresponding views of a modified form of shingle; Figs. 7 and 8 are plan views of further modified shingles; and Fig. 9 is a plan view showing how a further modification may be cut from strips of shingle material.

In making these shingles, the method pursued is to take sheets of suitable shingle material, such as ordinary felt and produce on one surface bands of various colors running across the sheets, preferably running longitudinally of the sheets. These bands may be formed by the use of granulated minerals of different colors, or by applying coats of coloring matter to the sheets after the mineral substance, such as slate, has been applied. The strip is then cut up in a suitable manner into individual strips or shingles so formed that, in applying the shingles to the roof, the adjacent shingles in the same row will be reversed with reference to the way they were when out from the sheet of single material.

In this instance, I prefer to cut a strip into individual shingles 10, each shingle having a slit or slot or recess 11 in one side and at an adjacent corner a lug 12. When theshingles are assembled, the lug 12 is passed through the slot 11 of the adjacent shingle and the lug passes down under the shingle so 1928. Serial No. 277,157.

that the two shingles are locked together. By having the lug inclined upwardly, as indicated, the lug cannot readily be pulled out of the slot 11. By keeping the lower edges of the shingles in line, the shingles will be properly positioned with reference to each other and a united row of shingles will be formed, which may be lapped upon the adjacent lower row as much as may be desired; prefierably, this lapping is the width of one When the rows of shingles are so formed, if the marking of the shingle is proper, the bands will be broken up so that, in no instance, will similar bands on different shingles register with each other, thus each row of bands along the roof is discontinuous so far as the color or light effects are concerned.

The method which I pursue to accomplish this is to provide an even number of bands on the shingles. When the shingles are assembled, as stated, they are reversed with reference to their original position in the sheet and, as a consequence, if there was an odd number of bands, the central band of one shingle would register with the central band of the adjacent shingles and, hence, there would be no break in the appearance of this band on the roof. But,-with an even number of bands, this does not occur. The number of bands otherwise is not very material, provided only that each band is unlike each of the other bands.

Hence, my method, in general, consists in providing an even number of bands on the portion of the sheet which is to form the shingles, and in cutting the shingles so that each .may be reversed with reference to the adjacent shingles when assembled. In this way, no further attention need be given to the positioning. of the various shingles or the bands thereon when the shingles are cut or packed for transportation or when they are being laid .on the roof. When being assem bled, the operator need pay noattention to the bands on the shingles as they automatically will be positioned so as not to register with similar bands of the adjacent shingles.

However, if desired, an odd number of bands may be provided and, in this way, a

continuous band will be formed across the roof in the central portion of each row of shingles and, between these continuous bands, will be one or more of the discontinuous or broken bands. This method of forming the shingles is indicated in Fig. 9. When reversed and assembled, the roof will have alternating continuous and discontinuous bands.

I Eprefer to form the shingles as indicated by ig. 2 so that the longer diagonal is at an acute angle with the lower and upper edges of the shingle, with one edge 13 substantially straight, and with the other edge having serrations or steps therein. These steps I prefer to have right-angled and of the width of the bands so as to provide the rectangular shaped figures illustrated in Fig. 3. When the shingles are assembled, as indicated, the entire roof will be covered withfigures similar in shape but varying in light appearance. The edge 13, as it is entirely covered by the adjacent shingle. may be as indicated or may be straight and continuous entirely across the shingle, if desired.

The length of the figures is determined by the width of the shingle strips and the amount of lap, and the lap is determined b r the position of the slot 11 in the edge. An the width of the figures is determined by the width of the bands. So that the dimensions of the fi res may be easily controlled. Also, the width of the different bands may vary if desired.

Figs. 4 to 6 illustrate a modified form of shingle in which the sides 15 of the steps are made curved and the angles 16 and 17 are obtuse. As a consequence of this arrangement, :1 wave line is produced at the end of each of the rectangular color sections, thus producing a novel and pleasing appearance on the roof which is materially unlike that of the shingles of Figs. 1 to 3. The method of producing the shingles 14 is substantially the game as the method of producing the shingles Figs. 7 and 8 show further modified shingles which may be produced in substantially the same manner and which provide figures on the roof which are very similar to the figures provided by the other types.

Fig. 9 shows a further modification and a method of cutting the shingles from the strips without waste. This also illustrates the shingle strip with an odd number of bands which would produce, when laid on a roof, a continuous band of one light effect alternatin with broken bands of various other light e ects. This general effect may be produced by (providing shingles with five or seven bands an in such cases, there will be two or three discontinuous bands alternating with one continuous band efiect.

Other modifications might be made in the details of the shingles without. departing from the spirit of my invention as disclosed by the following claims. A particular feature of my invention, however, is the provision of shingles which produce the figures without causing the ends thereof to register with the figures in the adjacent bands, so that each figure is distinctly emphasized by being in dependent of each of the other figures.

In order to more definitely define the bands and particularly the figures, when the shingles are assembled, definite stripes may be formed on the shingles after cutting or on the shingle material sheets before cutting between the bands, such as the stripes 20 of Fig. 7. Referring to Fig. 3 it will be seen that the rectangular figures are more clearly defined by the edges 21 of the shingles than by the lines of demarcation 22 between the bands. But, by applying stripes 20 between the bands, the figures are clearly defined on all sides.

Particular attention is called to the fact that in each of these modifications the lines of demarcation lie in an extension of one ot the shingle edges. Thus, Fig. 2, the lines 25 are continuations of the respective edges 26; so that the figures have certain straight sides. each formed by a line and edge, one lying in the extension of the other.

I claim asmy invention:

1. A method of making shingles consisting in formin on a sheet of shingle material bands of unlil re color-efiects, in formlng on one pair of opposite edges of the sheet lugs and slots, and in cutting across said sheets so as to form strip shingles, each'having a lug on one end adapted to interlock with a slot on the other end of an adjacent shingle of the parent sheet when assembled on the roof to cause registration of unlike bands with one another.

2. -A method of making shingles consisting in forming on a strip of shingle material longitudinal bands of unlike light effects, in forming on the side edges of the strip lugs and slits which are adapted to coact respectively with similar slits and lugs and in cutting the strip across so as to form individual. shingle strips, each with :1 lug and a slit on one end, and in making the alternate cuts across the strip along zigzag lines.

3. A method of making shingles consisting in forming on a strip of shingle material lonitudinal bands of unlike light effects, in fiorming on the side edges of the strip lugs and slits which are adapted to coact respectively with similar slits and lugs, in cutting the strip across so as to form individual shingle strips, each with a lug and a slit on one end, and in making the alternate cuts across the strip along zigzag lines, the zi ag lines comprising straight sections, the a ter' nate sections being parallel with said bands and the others at right angles thereto, the said lugs and slits being so positioned with relation to one another as to cause registration of the bands of one shingle with the bands of an adjacent shingle when interlocked in assembly.

4. A plurality of shingles assembled on a roof in courses each shingle having the general shape of an oblong, oblique-angled parallelogram, but having steps in one of the long edges, a lug projecting outwardly into the first step ad acent one short edge, and a slot in said short edge coacting with a lug of the adjacent shingle in the same course, each shingle having an even number of bands of unlike light effects on one surface substantially parallel with one short edge, the bands of some of the shingles being unlike the registering bands of the adjacent shingles.

5. A method of making shingles consisting of forming on a sheet of shingle material bands of unlike colornefl'ects, in forming on one pair of opposite edges of the sheet locking portions and in cutting across said sheet so as to form strip shingles, each having locking portions on one end adapted to interlock with looking portions on the other end of an adjacent shingle of the parent sheet when assembled on the roof to cause registration of unlike bands with one another.

6. A method of making shingles consisting of forming on both edges of a sheet of shingle material alternating lugs and slots, and in cutting across said sheet so as to form strip shingles each having a lug and slot in connection therewith, the lug and slot of one strip being on the opposite edge of the parent sheet from the lug and slot of an adjacent strip so that half of the strips cut from the sheet must be reversed when they are laid on a roof to cause registration of unlike bands with one another.

7. A plurality of shingles assembled ona roof in rows, each shingle having a plurality of bands of unlike light effects which are adapted to be exposed on one surface thereof, the bands of some of the shingles being unlike the registeringbands of adjacent shingles,and

locking means in connection with each of the shingles engaging locking means of an adj acent shingle said locking means being so positioned as to cause registration of unlike bands with one another.

8. A plurality of shingle-s assembled on a roof in courses, each shingle having one side edge formed with steps, a lug projecting outwardly from the first step adjacent the lower edge, and a slot in said lower edge spaced from the lug, said slot coacting with the lug of an adjacent shingle in the same course, each shingle having a plurality of bands of unlike light effects substantially parallel with the lower edge, the band's being substantially equal in width to the steps and the bands of some of the shingles registering with unlike bands of adjacent shingles to create a varied, ofl'set' brick-like effect.

9. A plurality of shingles assembled on roof in courses, each shingle having one side edge formed with steps, each shingle having a plurality of bands of unlike light efi'ect formed thereon substantially parallel with the lower edge, the bands being substantially equal in width to the steps, and locking means on one shingle cooperable with complementary locking means of an adjacent shingle to cause registration of certain bands of one shingle with unlike bands of an adjacent shingle to create a varied, offset brick-like arrangement.

10. The method of producing a shingle strip comprising forming on a web of shingle material longitudinal bands of unlike light effects, cutting said web along transverse lines which extend in stepped formation across the web, each step of said transverse lines being equal in length to the width of one of the longitudinal bands of the web or multiple thereof, and cutting the web on other transverse lines of other configuration positioned between pairs of said first mentioned lines so as to produce similarly shaped shingles with reversed complementary color patterns.

11. A plurality of shingles assembled on a roof in courses, each shingle having one side edge formed with steps and having a plurality of bands of unlike light effects substantially parallel with the lower edge,.said steps being equal in width to a band or multiple thereof, alternate shingles having bands of complementary light effects and being positioned with their complementary bands in reverse position to create a varied offset brick- 12. Shingles having bands extending longitudinally thereon of contrasting color efi'ects, said shingles having transverse edges with stepped portions therein, one ofsaid steps having a width at least as great as a multiple of one of the other steps, and being located adjacent the uppermost longitudinal edge, each step having within its transverse extremities a band or multiple thereof.

13. A pair of shingles adapted to be laid in alternate relationship on a roof, each shingle having its unexposed edge complementary to the unexposed edge of the other shingle and having stepped exposed edges, the steps being coincident with horizontal unlike bands of color, said bands being complementarily reversed in alternate shingles whereby a varied offset brick like effect is created in an assembly of such shingles.

In testimony whereof, I hereuntoset my hand.
