Application filed January 25, 1923. Serial No. 614,784.

This invention relates to a rocess of around the roller 11 and under a receptacle forming roofing materials and t e product 12 from which granular particles 13 of wearthereof. It relates more particularly to the resisting material such as crushed stone, type of roofing material which is formed slate, etc., are sprinkled thereon. As the from a base of fibrous or felted material areas 4 of lastic material are still warm that is saturated with water-proofing maand sticky, t e particles 13 will cling thereterial and then coated with plastic material to, but the particles which fall outside of' which has wear-resisting material such as these areas upon the cool, hard coating 2 will mineral -matter applied to the outside surnotstick thereto but will fall off when the lo face thereof. sheet is turned. As the sheet passes from The invention will be understood fromthe under the container 12 it may be caused to description in connection with the accompass between pressure rolls 14, 15 which will panying drawings in which serve to press the granular particles 13 more Fig. 1 is a plan view of the roofing sheet; firmly into the plastic material 4. The in Fig. 2 is an edge view of same; and plastic material will preferably be applied to Fig. 3 represents in part mechanism showin shapes indicated in Fig. 1 and in such a ing how the article can be made. manner that an' uncoated marginal edge 16 In the drawings, reference character 1 and the strips 17 of the coating 2 will be designates a base of fibrous material which left exposed.

2 may be made from paper making stock or In applying the strip of roofing material other fibrous materlal and may then be to a roof deck, it may be laid either horizonsaturated with liquid waterproofing material tally or vertically or at an acute angle to such, for example, as tar, by passing the the edge of the roof. After the first sheet same through a bath of the waterproofing 1 has been laid along the roof, cementitious 1J1 material as is common and well known in material such as hot tar or soft asphalt, for this art. The waterproofed sheet 1 may then example, may be applied upon the uncoated have applied to one side thereof a layer 2 of portions 3 and then a second strip laid thereplastic material such as pitch or asphalt, for .over with its lower edge in contact with the example, which may be applied in the hot exposed edge 16 of the coating layer 2 and an or liquid state in the usual or well known so on until the entire roof is covered. The manner and then be allowed to cool and exposed strips 17 of superposed layers may harden. This layer 2 will preferably be apbe made to lie in the same line with each plied along one edge of the sheet 1 thereby other orthey can be staggered.

. leaving a wide uncoated margin 3. The spots orareas '4 may be applied in 35 After the coating 2 has been applied, cershapes other than rectangular and the color tain sections or areas of the same may be of the mineral particles 13 should in all cases covered with or have applied thereto a coatbe such as to contrast with the color of the ing 4 of plastic bituminous material such as coating 2. By the use of these strips an atasphalt, for example. In Fig. 3 is illustractive looking roof can be made havin the 40 trated somewhat diagrammaticall a device lines 16 and 17 of contrasting color wit the 5 by which the spots or portions of t e coatin mineral matter 13 so as to make patterns 2 may have the plastic material 4 applieof the desired sort. thereto in segregated areas. In this figure I claim: reference character 6 designates a tank in 1. A strip of roofing material having a 45 which the plastic material 7 may be kept in layer of plastic waterproofing material on a plastic or semi-liquid condition by being one side thereof free from mineral surfackept hot in any convenient manner.

A strip of roofing material having a coatin 2 in the areas designated by refer layer of plastic material on one side thereof 5 ence c aracter 4. The sheet then passes free from mineral surfacing material, portions of said plastic material being covered with a layer of plastic material homogene-i base saturated with waterproofing material,

a layer of plastic waterproofing material on one side thereof free from mineral surfacmg material, portions of said layer of like areas being uniformly thickened by a second layer of plastic waterproofing material homogeneously united with the first layer and Wear-resisting material partially embedded in the surface of the thickened portions. I

4. A roofing strip consisting of a fibrous base saturated with waterproofing material, a layer of plastic waterproofing material approximately one half the width of the strips, applied to one side and at one edge thereof'and free from mineral surfacing material, portions of said layer of like areas being uniformly thickened by a second layer of plastic waterproofing material homogeneously united with the first layer resisting material partially embedded in the surface of the thickened portions.

5. A roofing strip consisting of a fibrous base saturated with waterproofing material, a layer of plastic waterproofing material, approximately one half the width of the strips, applied to one side and at one edge thereof and free from mineral surfacing material, parallel portions of said layer of like areas being uniformly thickened by a second layer of plastic waterproofing material homogeneously united with the firstlayer and wear-resisting material partiall embedded in the surface of the thickened and wearportions, the outer edge of the thickened portions being substantially fluslrw'itligthe i of like areas and of a length less than the width of said layer being uniformly thickened by a second layer of plastic waterproofing material homogeneously united withthe first layer and wear-resisting material partially embeddedin thickened portions.

7. The process which comprises applying plastic material to one side of a roofing sheet, thickening portions of said plastic material by applying thereto and homogeneously uniting therewith a second layer of plastic material and applying wear-resisting material to said second layer while it is still in a plastic state.

8. The process which comprises applying plastic waterproofing material to approximately one half of one side of a roofing strip at one edge thereof, thickening parallel rectangular portions of said plastic waterproofing material by applying thereto and homogeneously uniting therewith a second layer of plastiomate'rial and applying wearresisting material to said second layer While it is still in a plastic state,

In testimony whereof I affix my signature.
