In the art to which the invention particularl' relates prepared roong consisting, gene l eral of a strip of suitable paper known as wool-felt paper, which'is impregnated and .coated with an asphaltic com ound andis i covered on one face with granu ated stone. of

uniform color, known as grit, is given the appearance of a shingle or tile roof by applying to the grit coated surface a pattern imita-L tive of the appearance of shingle or tile roofs,

the .pattern being usually composed of heavy stripes ofbla'ck to contrast'sharply with the light colored grit. A later development consists in cutting a patterned strip of this roofing a medial variated line to produce two 2.5 stri s which are laid in relatively overlapped f position with the variated edges in staggered relation to better produce the impression or better imitate a tile roof. p so Heretofore attempts have been'made to cut variated pattern line in order that the variated edges of the resulting pair of strips may be bordered by an appreciable black edging but these attempts have failed by reason of the difficulty involved in passing this coarse and fairlyinexible material through a cutting machine withaccuracy, the usual result of such attempts having been that the line of severance at one end of the .roofing stri was wholly out of register with the variated pattern stripe lat at least one end y ortion of the strip. To produce marketale strips having variated edges bordered by such a black line from a patterned strip having a medial variated pattern stripe, the line "of severance lmust be midway between the side edges of said stripe.

The present practice is to impregnate and coat the paper strip with asphaltic compound such lpatterned strips by machines -along a.

and While the coating is still very plastic tol apply the grit and then allowv the material to cool and set, then apply the pattern stripes and thereupon pass the strip through the cutting machine, these operations bemg in many instances successive and continuous andv being followed by rolling up and cuttin the strip into iven lengths, the cutting mac ineiserving on y to deeply score but-netto com-v I pletely sever the strlp in order that the same may be rolled up. l

Manufactures of this type of roofing use various methods of rendering 1 thepaper weather-proof. A In many instances the paper is first passed through a vat of-an oilysubstance which easily penetrates, is then vcov-A ered with an asphaltic compound on. 'one or both faces and thereafter .goes lthrough 4the remaining steps above described. In such treatment the-asphaltic coating is mainly relied upon to impart the requisite 'weatherproof characteristics. In severing this typeof strip the exposed variated edges-not only lack the deep black color` of the asphaltic coating but subject the less weather-proof'body more directly to the action of the elements with the result that the life of the roofing is shortened.

Inl other instances,- the manufacturer impregnates the rooting .paperby boiling the same in anasphaltic compound, which, if it completely-penetrates the paper, renders the same deep black throughout and more thoroughly weather-proof but such complete penetration is not always effected so 4that upon exposing va severed edge of such roofing the unimpregnated portion-'will absorb moisture and rapidly deteriorate.

. Fig. .9 is a viewsimil'ar'v to Fig. 6 showing a diierent pattern.

Fig. 1() is a fragmentary detail section of a printing roller constructed to produce roofing strips ofthe present invention.

'the same to the grit-coated undersurface of a roofing strip-passing vbetween said roller 1 and a roller 2 disposed above the same and which .bears firmly upon saidstrip. Disposed in advance of the

rollers

1 and 2 are rollers d and 5. which serve to guide the roofing. The

rollers

1 and 2 are preferably driven'and geared to rotate in unison in respectively opposite directions by suitable gearing. l

The roller 1 has a pattern face adapted to apply or print'upon the grit face of the roofing strip a pattern in relatively broad stripes, said pattern, in the instance illustrated, being the conventional one shown in Fig. 6 which includes the zig-zag' or variated medialv stripe 6. The said pattern face consists of ribs 7 which are suitably equipped midway between their side ed es with cutting or scoring blades 8, said bla es, in the instance illustrated, being confined 'to that ,portion of the roller 1 which imprints upon or applies to the roofing the medial variated stripe 6. The

bladeor blades 8 is of a height somewhatA less than the thickness of said strip so as to deepl score without severing the latter so .that 1t may be rolled up and/subsequently severed without the use of tools by merely pulling upon opposite side edge portions of the strip.

The blades 8 serve further to collect upon their faces a. coating and in the corners formed by the same and the ribs'6, fillets of the liquid. This liquid penetrates into the edges of the strip after severance.

cnt or scoring ofthe and coats in whole or 1n part the opposed walls of the cut or scoring respectively which forms the exposed Thus the resulting product dilfers from the strip orshingles heretofore cut from a strip in.

that the exposed edges ofthe product are coated with the. weather-proof material 9 usedfor lproducing the pattern stripe and also in that the said edges are bordered by pattern stripes of uniform width.

In the patterns shown in Figs. 6 and 8,

Astraight stripes extend in staggered relation from the apexes of the medial variated stripe toward the side edges of the strip and while, in 4the instance illustrated, the blades 8 are 4not mountedin the ribs for producing said straightstripes, they may obviously be provided to extend to the side edges of the strip if it be desired to score the same so that it may be readily severed to provide shingles.

For clarity of illustration, the pattern stripes of Figs. 6 and 8 are not shown in the solid black of Fig. 7 in order that thel severance line 10 may clearly show, the roong vstrip of Fig. 6 being shown as partly severed at the left hand end portion.

In some instances the variated stripe 6 is omitted and the staggered stripes 11 only are with the knife blade or blades 8 but the rib 7 will be omitted.

It will be readily appreciated that the illustration and description of the machine used in producing the roofing strips of this invention is resorted to as constituting the best manner in which to present a clear description of the product of this invention without limitation of the latter to any particular machine or method of producing the same.

l claim as my invention:

1. As an article of manufacture, a strip of prepared roofing bearing an overlaid pattern composed of stripes of a coagulated liquid weather proof material and scored along at least some of the pattern lines in register with the latter for permitting easy severance of said strip to provide therefrom roofing elements,th e overlaid material substantially filling the scorings and providing coatings for the edges of the elements resulting from severance of the strips along the scorings.

2. As an article of manufacture, a strip of prepared roofing bearing an overlaid pattern composed of stripes of a coagulated liquid' weather proof material and scored along at least some of the pattern lines and midway of the side edges of the latter for permitting severance of the strip into roofing elements, the overlaid material substantially filling the scorings and providing coatings for the edges of the elements resulting from severance of ,3 the strip along the scorings, said edges bordared by overlaid stripes of uniform Width.
