COMPOSITION ROOFING.

Original application filed December 28, 1820, Serial No. 433,628. Divided and; this application filed May 19, 1921. Serial No. 470,914. Renewed October 25, 1923.

To all whom it may concern.

Be it known that I, ALEXANDER S. SPEER, a citizen of the United States, residing at Buffalo, in the county of Erie, State of 6 New York, have invented certain new and useful Improvements in Composition Roofing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others- 10 skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in composition roofing and analogous building material or the. like and particularly to 1 such material having identifying data thereon such as trademarks or the like.

Among other objects the invention is intended to provide composition roofing or the like, such as asphalt roofing having desi or marks on one side thereof which do not result in any marring of the face side of the material but which, nevertheless, are clear and distinct and cannot be readily obliterated.

In the drawings, I

Figure 1 is a perspective view of the printin and platen rolls,

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

In the manufacture of composition roof-, ing, it is desirable to impress data, as for instance a trademark, upon the under face, that is that face of the web or sheet which will not be exposedto the weather. It 1s also desirable to make the impressions while the roofing is in course of manufacture, that is before it passes from the machine on which'it is made. At this time the web or sheet is in a warm and plastic condition, and relatively soft, so that it is diflicult to impress a mark of sufficient depth to prevent obliteration in handling, without mar-- ring the opposite face of the web. If considerable pressure is used, that portion of the web containing the impression will be 'ofiset, presenting an embossed surface on the opposite face.

In order to obtain a clear-cut impression,

without any offsetting of that portion of the web containin the impression, I use a die havin raise printing characters of greater height than the depth of the impression desired, and I so limit the movement of this die toward the web during printing or lmpressing, that only a portion of the depth of the 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. In order to prevent sticking of the material to the die, I keep the surfaceof the die and of the roll upon which it is mounted lubricated by any suitable material,

as for instance soap water, or kerosene.

In the -manufacture of the composition roofing, a body of felted material is provided, as for instance of shredded rags and the like, and this body is immersed in asphaltum of a suitable consistency and saturated therewith. One 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 impressions or designs are on the reverse face, and.- the said designs 'or impressions are madewhile the finished web is warm and plastic.

In the mechanism shown, 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 for various thicknesses of the web, and to prevent injury from lumps of asphalt and the like which may be upon the web. o

The printin roll has upon the peripheral surface thereo a series of depressions 4, the

depressions corresponding in spacing and acters are of greater height than the depth of the 'ini ression desired, and the blank surface 0 the die is spaced within the peripheral surface of the roll, so that that portion of the web which receives the im-' pressions is engaged only by the printing characters, and not by the b ank surface of 8 of felt or .like absorbent material.

the die. Thus there is no pressure on the web at this point other than the pressure of the printing characters themselves. The printing roll may be arranged above or be low 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 printing 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 printing roll 2 runs in contact with a roll 7 having a facing This facing is soaked with the lubricant, in any suitable manner.

lln making the impressions, it is essential that they be alike, regardless of the thickness of the web and of its consistency. It 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-an rangement of the die as above described, with only those portions of the characters extending beyond theperipheral surface of the roll which actually penetrate the web insures that the impressions will be cut to the same depth regardless of the thickness of the web and of its consistency.

This application is (livision of my ap plication Serial No. 433,623, filed December 28, 1920.

ll claim 2- 1. As an article of manufacture, a composition sheet or web having its under face provided at regular intervals with impressions or designs cut in said face.

2. As an article of manufacture, a composition sheet or web having its under face provided at regular intervals with impressions or designs cut in said face, the impressions being similarly arranged and in a definite pattern.

3. As an article of manufacture, a composition rooting shingle comprising felt saturated with asphaltum and having its top faced with pitch and acrushed mineral, the lower face of said shingle being provided with a design cut therein. substantially as described.

at. As an article of manufacture, compo sition rooting comprising felt saturated with asphaltum and having on its top a layer of pitch. the under surface of said elt bearing a design cut therein while said asphaltum was warm and plastic, substantially as described. I

5. As an article of manufacture, composition roofing comprising felt saturated with asphaltum and surfaced as usual with crushed mineral, the under surface of said roofing bearing a trade mark cut into the felt, substantially as described.

6. As an article of manufacture, a sheet of relatively soft building material provided on its under side with a design or trademark formed by relatively thin lines cut into the material.

7. As an article of manufacture, trademarked building material, such as asphalt roofing or the like, having on its under side at intervals a trademark or other identifying data, the outlines of which are formed by relatively narrow cuts into the under side of the material which do not displace or mar the outer face of the material.

8. As an article of manufacture, asphalt roofing having an outer or wearing surface and provided on its under face at regular intervals with designs or identifying data formed by lines consisting of knife-like cuts into the under face of the material which do not disturb or mar the wearing face of the material.
