To all whom it may concern: 1

Be it known that LAIJEXA'NDERS. Srnnn, a citizen of the United States residin at Buffalo, in the county of Erie,-tate'of ew York, have invented certain newand useful improvements in Composition Roofing and Methods of Making the Same; and l do hereby declare the following-to be a full, clear, and exact description of the invention, such 8.S'.,-Wlll enable others skilled in the art to which it appertains to make and use the same.

- My invention is an improvement incomposition roofing and the like, and'i'n methods of makin the same, and relates more especially to t e impressing of identifying data, as for'instance trademarks and the like, on

the roofing while it is in a warm and plastic condition. i

I An object of the invention is to provide a composition sheet or web having'on one face at regular intervals impressions or designs cut in the said face.

.' Another object of the invention is to provide a method of making such impressions on the under face of the web or sheet, in such manner that while the impressions will be clear-cut and of'suficient depth to pre;- vent obliteration in handling they will mark the one face only and will not in any manner'mar the other face by offsetting the web or sheet or the like;

' In the drawings- Fgure 1 isa perspective View of the printing andplaten rolls.

Figure 2 is an enlarged transverse section of a part of the printing roll.

In the manufacture of composition rooting, it is desirable to impress data, as forinstance a trademark, upon the under face, that is that face of the Web or sheet which will notbe exposed to the weather. It is also desirable, though not thought necessary, to make the impressions while the roofing is 5 in course of manufacture, that is before it passes from the machine on which it 1s made.

At this time the web or sheet is in a warm and plastic condition, and relatively soft, so that it is difiicult' to impress a mark of sufiicient depth. to prevent obliteration in to handling; without marri'n the opposite face of the web; lit considerab e pressure is used, that portion of the web containing the impression will be ofiset, presenting an em bossed surface on the opposite face.

lln'order to obtain 'a" clear-cut impression, without any ofisetting of that portion of the web containing the impressiomlusa'for example, a-die having raised printing'characters of greater height: than the depth of the impression desired, and I so limit the movement or this die toward the web during printin or impressing,-that only a portion of. the epth .ottlie printing characters will enter the material of the web and the blank surface of the die will not contact with the web. Thus the impression is cut in the web and any displacement of the material is lateral and not toward the opposite face. In order to prevent sticking of the material to the die, it keep the surface of thedie and of the roll upon which it is mounted lubricated by any suitable-material, as for instance soap water, or kerosene.

lln theimanutactureof the composition roofing, a body .Tof felted, material; is provided, as for instance of shredded rags and the like, and this bodyis 1- erssd' in asphaltum of a suitable consistency and saturated therewith. Une'face .is then faced with pitch, and upon the pitch a mineral in a crushed state is placed, and in laying the roofing, it is this face having the crushed mineral which is to the weather. The i.- pressions or'designsare on the reverse face, and thesaid desi s or-impressions are made while the finishe web is warm and plastic.

in the-drawings is illustrated one form of mechanism for performing the method above described.

In this mechanism, the web 1 as it passes from the machine on which it .is formed, is passed between a pair of rolls 2 and 3, the former being a printing roll, while the latter is a platen roll, and one of the rolls is mounted to yield away from the other, to compensate i'or various thicknesses of the web, and to prevent injury from lumps of asphalt and the like which may be upon the web. The printing roll has upon the peripheral surface thereof a series of depressions 4:, the depressions corresponding in spacing and arrangement to the spacing and arrangement of the impressions desired upon the web. Within each of these depressions there is arranged a die 5, the said dies having printing characters 6 which extend above the surface of the die in the usual manner, and these characters have sharp ed es in order that they will cut the web an not merely indent it by displacing the material thereof toward the opposite face. The characters are of greater height than the depth of the impression desired, and the blank surface of the die is spaced within the peripheral surface of the roll, so that that portion of the web which receives the impression is engaged only by the printing characters, and not by the blank surface of the-die. Thus there is no pressure on the web at this point other than the pressure of the printing characters themselves and there is no tendency to displace the material of the web toward the opposite face. The printing roll may be arranged above or below the web, depending upon the character of the material being manufactured. For instance roll roofing is cut with the weather or top side down, and in operating upon this material, the rinting roll should be above. In cutting shingles from the web however, the weather side is up and the printing roll should be below the web in order to impress the designs on the bottom of the web. In either case the printing roll is lubricated, with any suitable lubricant, as for instance soap water or kerosene, and in the arrangement shown the rinting roll 2 runs in contact with a roll E having a facing 8 of felt or like absorbent material. This facing is soaked with the lubricant, in any suitable manner.

In making the impressions, it is essential that they be alike, regardless of the thickness of the web and of its consistency. If the impression or design is out too deeply, the web will tear, and if it is too shallow, it will be obliterated in handling. The arrangement of the die as above described, with only those portions of the characters extending beyond the peripheral surface of the roll which actually penetrate the web insures that the impressions will be out to the same depth regardless of the thickness of the web and of its consistency.

I claim: v 1. A method of impressing data on one face of sheets or webs of composition material without marring the other face, which consists in cutting the impression in the material by means of dies having raised characters of greater height than the depth of the cut desired.

neeopae 2. A method of impressing data on one face of warm and plastic sheets or webs of composition material without marring the other face, which consists in cuttin the impression in the material by means 0' dies having raised sharp edged characters of greater height than the depth cut desired.

3. A method of impressing data on one face of warm and plastic sheets or webs of composition material without marring the beyond the peripheral surface of the roll the depth of the impression desired.

5. A method of impressing data on one face of sheets or webs without marring the otherface, which consists in subjecting the web to uniform pressure except at that point on which the impression is to be made and in making the impression atsuch points while the sheets or webs are supported on the other face.

6. A method of impressing data on one face of sheets or webs, without marring the other face which consists in cutting such data in the material while the sheet or web is subjected to uniform pressure about the impression and on the opposite face from the said impression.

7. A method of impressing data on one face of warm and plastic sheets or webs, without marring the other face, which'consists in cutting such data in the material while the sheet or web is subjected to uniform pressure about the impressionand on the opposite face from the said impression and in cutting said impression with raised characters carrying a suitable lubricant.

8. The method of applying identifying data. designs or the like to the face of sheets of the character described without marring or disturbing the opposite face of the material. which comprises cutting data or the like in said face on relatively thin lines or cuts, so as not substantially to displace or indent the material of the sheets toward the other face.

9. The method of applying identifying data. designs or the like to the face of relating data o the like in said face on relatively thin lines by means of a sharp cutting terial, which comprises forming the impresedge while supporting said sheets on the opsions for the outlines of such data or the posite face. like by narrow cuts which displace the ma- 10 10. The .method of applying identifying terial laterally but not substantially toward 5 data, designs or the like to the face of sheets th her: face of the Sheetof the character described without marring n testimony whereof I affix my slgnature. or disturbing the opposite face ofthe ma- ALEXANDER S.
