PREPARED SHEET F COATING MATERIAL AND METHOD OF MAKING THE SE.

Application filed September 16, 1915.

- fication.

My invention relates to improvements in prepared sheets of coating material and the method of making the same. p

One of the general objects of my invention is to provide wearing or coating'material.

in sheets or strips, of ornamental design, for covering roofs, floors, side-walls or the like, of buildings and a methodofmaking same.

A more specific object of my invention is to provide a sheet or strip of fabric, such as felt, treated with hot Waterproofing material, such as asphaltum, or the like, and while said material is hot and adhesive applying strips, figures, or pieces made of preferably thinner strips, figures or pieceshaving non-adhesive faces to the coated, adhesive side of the sheet, to produce ornamental designs thereon.

Such strips or figures in some instances have first been coated with granular, or flaky grit, such as ground, crushed, or flaked material, as stone, sand, slate or other grit. And after said strips or figureshave been applied to the sheet, the intervening tacky or adhesive-containing spaces upon the main sheet are filled with similar grit or comminuted material of, preferably, a different or contrasting color, thereby producing conventional designs or figures, of van-- ous colors upon the sheet, as a whole. The applied strips, figures or pieces may be rela tively thin and composed of relatively cold asphaltic compound, the face of which is not adhesive when applied. 7

Other and further objects of my invention will become readily apparent to persons skilled in the art from a consideration of the following description, when taken in conjunction with the drawings.

1 When completed my improved coating or covering sheets may be employed as means for covering roofs; or the outer or inner walls of buildings, or for floors or the like. In carrying my invention into effect I provide a roll of fabric, preferably of felt, made in a continuous sheet;.I pass the sheet Specification of Letters Patent.

through a suitable receptacle containing hot asphaltum, tar or the like Waterproofing materlal, and then deposit upon the adhesive side of the sheet, strips or pieces of conventional design, or configuration, the upper faces of which are non-adhesive, and properly spaced apart. I then, after the superposed piece or strips are in place, deposit upon the adhesive surfaces of the main sheet granular or flaky material, such as slate, sand or the like, of a different or contrasting color, with the strips or pieces previously applied thereto. I then pass this strip and assembled pieces between rolls, to embed the comminuted grit into the underlying plastic adhesive, and to cause the pieces, that have been applied thereto to more securely adhere to the main sheet.

In the accompanying drawings, I show a conventional machine whereby and whereupon my sheet may be made, and wherein:

Figure 1 is a central, sectional elevation.

Fig. 2 is a plan view of the machine.

Figs. 3, 4, and 5 are plan views of several forms of the completed sheet.

In all of the views thesame reference characters are employed to indicate similar parts.

6 is a tank, or other suitable receptacle for containing a Water-proof, and weatherproofing material 7, such as asphaltum, tar

, or the like, which material is heated by the series of steam coils 8 contained in the bottom of the receptacle. A roll of felt 9 is mounted upon a shaft 10, passes over the roller 11 and under the roller 12 in the receptacle 6, and preferably, under the steam coils 8, and at the far end of the receptacle passes under another guiding roller 13, thereby causing the felt to traverse the hot material 7 near the bottom of the receptacle, so as to provide a uniform and dense coating upon both sides of the sheet. The sheet 9 then passes over the roller 14 at the top of the receptacle, and at the opposite end, having passed between scrapers 15 and 16, whereby excessive amounts of the material may be scraped from the sheet. A series of relatively narrow rolls of strips 17 are mounted upon the shaft 18 that is sup orted by the standards 19. These strips 1 pass under a roller 20 to bring them practically parallel with the sheet 9.

The strips 17 have been previously treated, referably, by being saturated with a simiar water-proofing material and having their upper surfaces coated with grit or the like, so that the said upper surfaces are substantially non-adhesive when used in the manner described. The strips 17 and the sheet 9 pass between pressurerollers 21 and 22. The latter roller is grooved, as at 23 to provide guides for the strips 17, so as to prevent them shifting laterally and to compensate for their thickness to some extent. The grooves 23 are not, however, so deep as to prevent the rollers 21 and 22 from pressing the strips into close contact with the hot,

adhesive upper side of the sheet 9. The sheet 9, with the adhering strips 17 now passes under the hopper 24., containing flaky slate,or other grit 25, which is preferably of a difiierent or contrasting color with the 'upper surface of the strips 17. The hopper 24 deposits and distributes the contents 25 upon the sheet 9 in the spaces intervening between the strips 17 The sheet 9 with its accompanying strips 17 is now passed under and over the rollers 27 to cool and between the pressure rollers 28 and 29, the grit material placed on the sheet 9 between the strips 17 is thereby embedded in the upper surface of the sheet, and the adhesive material 'being hot or warm at this time, the grit will thoroughly adhere, to the upper surface of the sheet and will not adhere to the upper surface of the strips 17. The finished sheet 9 may now pass into-the machine 30 which is adapted to transversely shear the strip as shown at 31 in vFig. 3, into shingle-strips, the representation of the shingles being determined by the contrasting lines, or strips 17. This subsequent operation of transversely shearing the sheet 9 and the attached strips, is only to be accomplished when it is desired to make shingle-simulating strips. When the sheet is desired for other purposes,

such as for sidings or for floors, or to be laid as a whole upon a roof, 1t 1s not necessary to transversely shear it into strips, as shown in Fig. 3.

After the strip has been completed, as shown in Figs. 3, 4, and 5, it is substantially of uniform thickness, and when laid upon,

floors or upon roofs there are no objectionable protruding parts. The grit being thoroughly embedded in the plast1c material superposed upon the sheet forms an' enduring, wearing surface of refractory particles which endure hard long Wear, and cannot be easily disengaged from the sheet.

While I have herein shown a preferred form and two modifications of, an embodiment of my invention it is manifest that it is susceptible of many further modifications,

. ventional designs, said sheet having its intervening adhesive surfaces covered with granular or flaky grit embedded therein, and of a color differing from or contrasting with the color of the exposed surfaces of said superposed pieces.

2. The method of making wearing covering sheets of ornamental design which consists in treating a suitable fabric with a hot waterproof adhesive material; placing upon the sheet while hot strips or pieces of fabric previously treated with waterproof adhesive in the upper surface of which has been embedded a coating. of granular or flaky material; pressing the strips or pieces upon the hot adhesive surface of the sheet; and while the adhesive surface of the sheet is-still hot depositing thereongranular or flaky material of a color contrasting with that upon the strips I or pieces and passing the sheet between rolls to embed said granular material in the adhesivesurface of the sheet.

In testimony whereof I hereunto set my hand in the presence of two subscribing witnesses.

MARY F. ALLEN.
