Patented Oct. 3, 1933 MACHINE AND METHOD FOR PRODUCING ROOFING Robert B. Levis, Chicago, Ill., assignor to Bird & Son, Inc., East Walpole, Mass., a corporation of Massachusetts Original application January 3, 1928, Serial No'.

Divided and this application August 3, 1929. Serial No. 383,250 I 14 Claims. (Cl. 91-67.9)

This application is a division of my application for patent, Serial No. 244,331, filed January This invention relates to the art of prepared roofing and more particularly to that class of roong whichis of the shingle type and bears a pattern having for its purpose to cause such rooiing to have an appearance similar to tile roong.

The present invention has for its objects, rst, to provide a novel method of producing roofing per se possessing certain novel characteristics hereinafter described, and second, to provide a novel and efficient machine or apparatus to carry out the method and produce the roofing.

In the artv to which the invention particularly relates, prepared roofing consisting, generally, of a strip of suitable paper known as woolfelt paper, which is impregnated and coated with an asphaltic compound and is covered -on dne face with granulated stone of uniform color, known as gri, is given the appearance of a shingle or tile roof by applying to the grit coated surface a pattern imitative of the appearance of shingle or tile roofs, the pattern being usually composed of heavy stripes of black to contrast sharplywith the light colored grit. A later development consists in cutting a patterned strip of this roofing along a medial variated line to produce two strips which are laid in relatively overlapped position with the variated edges in staggered relation'to better produce the impression of or better imitate a tile roof.

Heretofore attempts have been made to cut 35 such patterned strips by machines along a vari- .ated 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 diiculty 40 involved inpassing this coarse and fairly inflexible material through a cutting machine with accuracy, the usual result of such attempts having been'that the line of severance at one end of the roofing strip was wholly out of register with the variated pattern stripe at at least one end portion of the strip. To produce marketable strips having variated edges bordered by such a black line from a patterned strip having a medial variated pattern stripe, the line of severance must be midway between the side edges of said stripe. One of the objects of the present invention is to provide a method and a machine for accurately producing a line of severance midway between the side edges of the variated. pattern line.

The present practice is to impregnate and coat the paper strip with asphaltic compound and while the coating is still very plastic, to apply the grit and then allow the material to cool and set, then apply thepattern stripes and thereupon pass the strip through the cutting machine, these operations being in many instances successive and continuous and being followed by rolling up and cutting the strip into given lengths, the cutting machine serving only to deeply score-but not to completely sever the strip in order that the same may be rolled up.

Manufacturers of this type of roong use various methods of rendering the paper weatherproof. In many instances the paper is first passed through a vat of an oily substance which easily penetrates the paper, which is then covered with an asphaltic compound on one or both faces and thereafter goes throughthe remaining steps above described. In such treatment the asphaltic coating is mainly relied upon to impart the requisite weather-proof characteristics. In severing this type of strip theexposed vari ated edges -not only lack the deep black color of the asphaltic coating-but subject the less weather-proof body more directly tothe action of the elements with the result that the lifel of the roofing is shortened.

In other instances, the manufacturer impregnates the roofing paper by boiling the same in an asphaltic ='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 that upon exposing a severed edge of such roofing the unimpregnated portion. will absorb moisture and rapidly deteriorate. To overcome this diiculty, my invention comprehends the production of a severed strip per se wherein the severed edges are coated with a weather-proof compound by a method which comprehends effecting such coating of the said edges simultaneously with the scoring of the strip medially of the variated pattern line, a further novelty of the method residing in simultaneously applying the pattern stripes, scoring the roofing medially of a pattern stripe or stripes and coating the opposed walls of the groove produced in scoring the material.

Reference may be had to the Becker Patents Nos. 1,024,549-1,024,5501,157,664-1,157,665- r1,222,594-1,256,508 for descriptions of machines, methods and materials particularly adapted for use in connection with the present invention, the latter relating wholly to the particular strucesl tural and method improvements of a mechanical nature without regard to specic materials used.

In the accompanying drawings illustrating the present invention in its various or several aspects, viz.: method, machine and product:

Fig. 1 is a diagrammatic section of a machine for applying pattern stripes to prepared roofing strips, the printing roller of said machine being constructed in accordance with the present invention.

Fig. 2 is a sectional View on the line 2-2 of Fig. 1.

Fig. 3 is a detail view of the printing and scoring roll of the machine.

Fig. 4 is a fragmentary sectional view of a patterned and scored strip of roofing.

Fig. 5 is a similar view on a larger scale of a 'severed section of the strip of Fig. 4.

Fig. 6 is a face view of a patterned and scored roofing strip partly severed.

Fig. 7 is a fragmentary view showing several severed strips laid in overlapped relation as on a roof.

Fig. 8 is a sectional view on the line 8--8 of Fig. 7.

Fig. 9 is a view similar to Fig. 6 showing a different pattern.

Fig. l0 is a fragmentary detail section of a printing roller constructed in accordance with the invention.

The nucleusof the present invention lies in effecting scoring of the roofing strip simultaneously with the application ofthe pattern stripes, the scoring being effected midway of any one or several of such stripes depending upon the specific ultimate product desired to be produced, the depth of the scoring being either so deep as to effect cutting and severing of the strip into shingles or of such depth as to permit of easy `severance by merely pulling apart the portions to be separated without interfering with the rolling of the scored strip.

Roofing strips are, in practically all instances, thirty-two inches wide and sixty feet long, each roll of a strip of these dimensions constituting one and one-half squares @150 sq. ft.) allowing for a two inch overlap on the roof.

Thus, inthe machine of Figs. 1 and 2, the printing or pattern stripe applying roll 1 is partly immersed inthe liquid, such as an asphaltic compound and contained in the vat 2, said roller thus carrying said liquid up to and applying the same to the grit-coated undersurface of a roofing strip passing between said roller 1 and a roller 3 disposed above the same and which bears firmly upon said strip. Disposed in advance of the rollers 1 'and 3 are rollers 4 and 5 which serve to guide the rooting. The rollers 1 and 3 are preferably driven and geared to rotate in unison in respectively opposite directions by suitable gearing.

The roller 1 has a pattern face adapted to apply or print upon the grit face of the rooiing 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 medial stripe 6. The said pattern face consists of ribs 7 which are suitably equipped midway between their side edges with cutting or scoring blades 8, said blades 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 blade or blades 8 may be of a height sufcient to cut through vthe roofing strip but is preferably of a height somewhat less than the thickness of said strip so as to deeply score without severing the latter so that it 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, iillets of the liquid. This liquid penetrates into the cut or scoring of the strip and coats in whole or in part the opposed Walls of the cut or scoring, respectively, which forms the exposed edges of the strip after severance. Thus the resulting product differs from the strip or shingles heretofore cut from a strip in that the exposed edges of the product are coated with the Weather-proof material 9 used for producing the pattern stripe and also in that the said edges are bordered by pattern stripes of uniform width.

Insofar as the invention comprehends the method above described, it consists obviously in combining in one step or operation the application of the pattern stripe, the cutting or scoring of the strip and coating the subsequently exposed edges of the latter with the material of the stripe to the depth of the incision made by the blades.

Insofar as the machine is concerned, the invention consists in providing the cutting or scoring blades disposed upon the pattern printing ribs of the printing roller in Whatever position relatively to the side edges of the printing ribs it may be desired to dispose the same, though in the instance illustrated, said blades are disposed midway of the side edges of said ribs.

In the patterns shown in Figs. 6 and 8, straight stripes extend in staggered relation from the apexes of the medial variated stripe toward the side edges of the strip and While, in the instance illustrated, the blades 8 are not mounted in the ribs for producing said straight stripes, they may obviously be provided to extend to the side edges of the strip, if it be desired to cut the same into shingles or score the same so that it may be readily severed to provide shingles.

For clarity of illustration, the pattern stripes yof Figs. 6 and 8 are not shown in the solid black of Fig. 7 in order that the severance line 10 may clearly show, the roofing strip 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 applied. It will be obvious that in cutting or scoring a strip to which only the pattern stripes 11 are applied, along the variated line l0, the alternate angles of the latter must register, with the said stripes ll. I will be obvious, without specific illustration, that in such f cases the roller l will be equipped with the knife blade or blades 8 but the rib 7 will be omitted.
