BRANDING noorING.

,Application led December 28, 1920, Serial No. 433,624. Renewed October 9, 192,2. Serial No. 593,462.

To ad whom it may concern:

Be it known that I, ALEXANDER S. Sraan, a citizen of the United States, residin at Buffalo, in the county of Erie, State of ew York, have invented certain new and vuseful Improvements in Branding Roofing; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to .makeand use the same.

This invention relates to improvements in apparatus for branding composite sheet building material, such as composite roofing.

Among other objects the invention is intended to provide noveland improved yapparatus for placing designs or identifying data on such materials without marring or disturbing the face side thereof, but whichdesigns or data are nevertheless clearand distinct and cannot be readily obliterated.

The nature of the invention ma be best understood by reference to one il ustrative construction embodying the invention and shown in the accompanying drawing.

In the drawing Figure 1 is a side view of the improved machine, p

Figure 2 is a plan view of the printing or dieroll,

Figure 3 is an enlarged detailed section ofthe roll,

Figure 4 is an end view showing a modified arran ment.

I have i lustrated the invention in connection with` a machine for cutting asphalt roofing into unitspsuch, for example, as the machine of my Patent No. 1,%4,654, granted October 30, 1917, although, as will beob-A vious, the invention4 is capable of use independently of any other machine for handli-ng'or treating the material. Moreover, it is contemplated to employ the invention in connection with material which is formed into rolls and not cut into units.

Preferably the material is impressed with the designs, data or trademarks as one step in the continuous process of manufacture of the units of the material. This saves cost in handling and is otherwise a convenient mode of employing the invention. In the case of asphalt roofing, this material is still warm and somewhat soft and sticky when the designs are impressed therein. When the material is cut into a number of units,

the impression will be such as individual shingles or strips, it is desirable that each unit `bear the trademark or whatevery impression it is desired to place on the material.

To embody the invention in the machine of the patent above referred to I substitute for the feed or pulling rolls o f the machine forming the subject-matter of the above patent a printing or-die roll 1 and a platen roll 2, and I contemplate arrangin Y printing rolleither below the web as s own in Figure 1 or above the web as shown in Figure 4 for a reason to be presently set forth. The said machine comprises a frame 3 in which are journaled the rolls 1 and 2 in a manner to be resently described and this frame carries a so cutting rolls4 and 5,

which engage opposite sides of the web to cut the same in the manner set forth in the above mentioned patent. Between the cutting rolls and the printing and platen rolls the web passes over a table as shown, and the roll 2 is spring pressed toward the roll 1, the web passing between the said rolls. This arrangement permits the platen roll to coliform itself to varying thicknesses of the we The printing roll 1 or equivalent member is provided on its peripheral surface with a. series of depressions 6, and within each of these depressions there is arranged a die 7 The dies are so spaced on the die-roll that as the web passes between the rolls 1 and 2 properly placed on the web, to correspond with the arran ment of the shingles in the web. Each o -these dies, which bear any desired `figure or labelthe bodies thereof lie below the surface of the printing member and only a portion of the sharp cutting edges project above the surface. Accordingly, only the shar edges so projecting contact with the sur ace of the material to be impressed, avoiding any pressure upon the material to be impressed other than that exerted by the sharp cutting edges of the die.

The characters of each die have sharp edges, so that they will make a cutting impression, and will not substantially displace the material of the web toward the opposite face. Each character extends beyond the peripheral surfaee'of the roll a distance corthe lll

insonne responding to the depth of the pression desired to be' made upon the rooting.

lin order to prevent the roong from sticking to the die, means is provided for lubricating the face of the die-roll with a suitable lubricant, as for instance soap Water or kerosene. ln Figure 1 the under portion 4of the die-roll runs in a trough 8, which mark, label or the like must be on the un` dersideof the vveb ln cutting rooting however, the arrangement shown in Figure d is preferable.

ln this construction the die roller indicated at 9 is arranged above the vveb 10, and the platen roller 11 is arranged below the web. Both printing roll and platen roll are however, constructed in the manner shown in Figure l. '.lhe printing or die roller is lubricated by means of a roller l2 journaledv above the die roll, and having a facing 13 of felt or like absorbent material, which runs in contact with the peripheral surface of the die roll. 'lhis felt is soaked with a suitable lubricant, as for instance soap Water or kerosene.

ln 'both constructions the operation is the same. As the roofing is fed to the cutting rollers, and just before it is cut it is engage by the die roll, which prints at-rear intervals on the under surface of the vveb an impression of any desired character. Should the web be not of uniform thiclmess, yet the embossing will be alike throughout, since the platen roll and the printin roll may move toward and from each ot er in accortdance with the varying thicmess of the vve ln a machine of. this character it is essential that the impressions be alike, rerd less of the thickness of the vveb and regard less of its consistency. lf the desi 1s out too deeply the web will tear, and if it is too shallow it may be obliterated by handling. ln order to provide for a uniform impression regardless of thiclniess or consistency of the web, the die is mounted as above derscribed, with only that part of the characters extending beyond the peripheral surface of the die which actually penetrate the web. Such characters must have sharp edges, in order that they `will cut, and not odset the web, thus avoiding an marring or 'disturbing of the oppositesur ace of the material. 'l'he pressure vexerted upon the sheet by the sharp cutting e tende only to displaoe'the material of the web laterally and not in the direction .if the oppo= site face. lin the arrangement illustrated,

vthe roll a the individual cutting edges act on the material somewhat as a Wedge, making the n premion by cuttin the material and fore ing it laterally. lil providing a substantial portion of the cutting edges of the die below the surface of the printmg member, a space is provided which tends to prevent the accumulation of sticky material upon the dies yand the consequent gumming of the' knife-edged parts of the die.

Obviously the apparatus for impressin the designs in the rooting need not be used in conjunction with the machine illustrated. Moreover, the invention is not limited to the specific details of construction herein shown, but may be variously modied. Although itV is preferable to impress the material as one step of the process of manufacture, it is obvious that the invention may be embodied to impress the material at a subsequent stage, after the material has cooled, and either before or after the material is out into units.
