Application led November 8, 1917. Serial No. 200,856. Yl

To all 'whom t may concern.'

Be4 it known: that I, OWEN D. MCFAR- LAND, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Methods of Making Shingle-Simulating Roofing-Strips, of which the following is a specification.

The inventionrelates to'improvements in methods of making shingle-simulating roofing strips.

@ne of the objects of my invention is to provide a new method of making shinglesimulating strips, of ordinary asphaltic roofing material, .whereby to cheapen the cost. of production and to improve the artistic appearance of the nished strip.

' Other and further objects of my invention will become readily apparent, to persons 'skilled in the art, from a consideration. of

the followin description when taken in conjunction wi the' drawings, wherein Figure 1 is a schematic representatiomin elevation, of a continuous sheet of felt, or other like base, undergoing the process'of being made into shingle-simulatlng strips. Fig. 2 is a transversely extending shaft showing a .plurality of disks mounted thereon for removing vthe comminuted mineral ser ' Fig.5

material, to expose the asphalt therebelow .in longitudinally extending stripes.

Fig. 3 is a similar view showing disks for making the end stripes which are cut deeper into the sheet and are separately adjustable. ig. 4 is an end-view of one of the shaft bearin showing the manner. of adjusting the di s tow-ard and from the sheet.

Fig. 5 is a plan view of the sheet, showing the longitudinally extending stripes, and ink .dotted lines, the planes through which the sheet is to'b'e cut tov form thestrips. p `-Fig. 6 is fa section taken -on line of llnl llthe viewsithe' same reference characters are employed to indicate some of the parte. e y I I do not claim 'to be the first to -produce a shingle simulating strip bycovering .a

rial, and providing tending transverse sheet otasphaltic with a uniform coating ,of slate, or other mlneralormate.-

stripes at intervals, ex.

esuli od 'of producrelates to the particu ar met ing the article.

Heretofore strips of this character have been made by coverin certain portions of the asphaltic sheet', as y strips` of paper. or

the like, prior to the ap lication of the slate,`

or other coating, and su sequently removing the Vpaper to expose the asphalt. In other instances, certain portions of the sheet`V have been covered with sand orlike granular material, before the application of the. slate coating, and subsequently thesand has been embedded into the asphalt therebelow to produce the contrasting stripes between the areas coated with the slate. The stripes in' the sheet, as heretofore produced by the method referred to, are of indistinct outV line and are not as strongly contrastable with the slate coated area to produce thel best effect and furthermore the older methods, pursued as heretofore described, are

expensive and for this reason, undesirable...`

In carrying my invention into effect, I nass the sheet of felt, or other-suitable base, through'a receptacle, such as 10 containing hot asphalt 11, which is heated by thefurnace 12, therebelow.)` The Aslieet 13 passes over a roller 14 into the tank 10 and around a roller 15 and over the roller 16. The doctors 17 and 18 remove the excessive quantityl of asphalt from the sheet as it emerges rom` the `tank 10. The sheet is then passed between the driving rollers 19 and 20 and under the hopper 21 containing slate, or 'other like granular material, which is deposited' upon the topi surface of the sheet. The sheet, :hen .coated with slate throughout, its entire exten-t passes over the roller 24 into 'a tank 25 containing water 26.v The water is circulated through the tanky by suitablel means,

' to maintain ag uniform temperature and to 'carry away the heat coming from the sheet.

The sheet passes under a suspended roller 27, within the tank, and over another roller 2,8,

as .on the lines '35, shown in Fig. 5, to pro" vide the shingle simulating strips 36.7

ioo

Aat the top'oif'I the tank. It/is Vthen passed over the roller 29, under 'the roller 30, and

A shaft 37 extends `transversely of the sheet and is provided with disks 38, 39 and 40. These disks are of. metal andvphave smoothfaces, they may be either of steel or copper and when rotated rapidly in contact stripes 38 to 40 inclusive.

with the upper surface of the sheet, they very eii'ectively and thoroughly removescrews 43, at each end of the shaft 37, the relative height of the respective ends of they shaft may be adjusted so as to bring the disks 38, 39, and 40 more intimately into Contact with the underlying sheet. A pulley 45 is secured to the outer end of the shaft 37 and affords a means of rotating the disks. The standards 42 may be supported upon pillars 46 within which the shaft 29 carrying the roller 29, ind bearingl support.

The stripes 49 and 50, at the margin edges of the sheet are somewhat deeper than the I therefore mount the disks 51 and 52 on a separably adjustable shaft" 53, which "'finds bearings in the standards 42 and is supported and adjusted in the same manner as the shaft 37, being provided with a driving. pulley 54 securedto its outer end. The stripe 50 is also .somewhat Widerthan the'other stripes, so as to provlde suiiici'ent room for a lap for the' adjoining strip. I prefer to make the base portion, upon which the stripes 49y and 50 are made, somewhat thinner than the base portions underlying the stripes 38 to 40 inclusive, so that the interlap of the stripes will not become so clearly apparent.

It will be observed that the sheet 13 is stretched tightly and smoothly over the roll 29 Which confronts'the disks 38 to 40 inclusive, so that there are no Wrinkles or uneven surfaces presented to the disks, to facilitate the operation of the disks and to maintain the stripes at uniform distances apart and of uniform Width.' The sheet in like manner, is stretched over the roll 31 confrontingl the disks 51 and 52.

Having described my invention what I claim as new and desire to secure by Letters Patent is l. The method of making shingle simulating strips which consists in .covering a long sheet with an asphaltic material, continuously coating the entire surface of said sheet With a layer of granular or fiakey mineral to provide a substantially contrasting color to said asphaltic material, continuous'ly removing part of said mineral material to expose the contrasting asphaltic material therebelow in a plurality Iof continuous and unbroken stripes longitudinally disposed on said sheet, continuously moving said sheet While the milieral is applied and removed, and cutting said sheet transversely across' said stripes into strips in imitation of shingles.

2. The method of making shingle-simulating strips which consists in covering a relatively long, narrow sheet with hot asphaltic material; coating the entire surface of said sheet With a layer of granular or flaky material of substantially uniform color; passing said sheetunder rapidly rotating disks to remove the mineral material 75 thereby exposing the contrasting asphalt therebelovv in parallel stripescontinuously moving said sheet, and cutting said sheet transversely across said stripes into strips in imitation Pof shingles.

3. The method of making shingle simulating strips which consists in covering a long sheet with. hot asphaltic material, coating the entire surface of said sheet with a layer of granular or flaky material, continuously removing part of said lmineral material to expose the contrasting asphaltic material therebeloW in a plurality of continuous and unbroken 'stripes longitudinally disposed on said sheet, the stripes being located intermediate the edges of the sheets and also at the edges of the sheets, the material being removed to a greater depth at the edges ofthe sheet than for the intermediate stripes, -and cutting said sheets transversely across said stripes into strips in imitation of shingles.

l4. "A shingle simulating strip comprising abacking having a'layer of asphaltic material with one of its faces covered in con- 100 tinuous zones With granular or 'laky material to give it color, said zones being divided by continuous transversely extending stripes exposing the asphaltic material beloW the flaky material and said strip having continuous marginal endstripes, one of said -end stripes being of substantially ythe same hand in the presence of a subscribing Wit- 115 ness.
