METHOD AND APPARATUS FOR ORNENTING MINERAL-SURFACE!) ROOFING.

Application filed December 3, 1920. Serial No. 427,938.

To all w homit may concern:

Be it known that I, CARL J. PATER, a citizen of the United States, and a resident of Wyoming, in the county of Hamilton, State of Ohio,'whose post-ofliceaddress is 231 Grove Avenue, l/Vyoming, Ohio, have invented new and useful Improvements in Methods and Apparatus for Ornamenting Mineral-Surfaced Roofing, of which the following is a specification.

My invention relates to method and apparatus for ornamenting prepared roofing, more particularly the ornamenting of mineral surfaced prepared roofing on which the ornamentations are made by compressing the mineral surfacing particles down into and covering them with the coating which before the ornamentation treatment underlies and holds the mineral surfacing particles in place. Roofings of this type are usually made by using a foundation of one or more plies, such as felt, paper, etc., saturated or impre nated with a suitable watefproof material such as asphalt or other bituminous substances and then coating with a suitable waterproofing compound, such as an asphalt compound or other bituminous compound to cover the foundation. Upon this coating is then applied mineral particles of either crushed slate, stone, pebbles, sand, mica or other particles of suitable fire-resisting .materials.

Roofings of this type are manufactured and sold without any ornamentations. When these roofings are used'where a more decorative surface is desired and they are sub jected to an embossing operation wherein a face of the mineral particles pressing the particles alongpredetermined lines down into and covering them with the bituminous coating which has been softened by the heated design roller. In practice it has been found that this ornamenting of the roofing by embossing results in a readjustment or reformation of the roofing along predetermined'lines and is facilitated by heating the roofing prior to the embossing operation. This heating of the roofing prior to the embossing operation however tends to cause it to adhere to the foundation on which it rests when the embossing operation is performed; it also stretches the roofing along the edges, and has other objections which I have found can be overcome and the speed of production greatly increased by subjecting the under side of the roofing to a film .or coating of liquid or other non-adhesive material preferably cool or cold water.

My improvement prevents the stretching of the roofing along its edges-which gives a fluted'efi'ect and prevents the roofing from lying flat on the roof when in place.

In the drawings in which like letters refer to like parts, Fig, 1 is a diagrammatic view of the apparatus of my improved apparatus. Fig. 2 is a cross section of Fig. 1 taken on the lines 2, 2 looking toward the right. A is the embossing roll having any suitable raised design on it. This roll is heated preferably by a flame A A which may be located on the inside or-outside of the roll or on both, fuel for which is supplied by pipes A A An suitable heating medium may be used. is the support-. ing or foundation roll upon which the roofing rests whilebeing embossed. The embossing roll A and the supporting roll B are driven in any desired wary, but as shown A is provided with a gear meshing with a similar ear Q, on the shaft of roll B. The gear is fixed to the shaft of roll A as is also the pulley R driven by belt or otherwise. If desired the roll A is mounted so as to'regulate the pressure-on the roofing on either or both ends of the roll. G

is a continuousbelt or carrier adapted to it. F is an idler roll to facilitate the rolling up of the roofing after the operation is applied. G is a steam coil or other suitable means for heating "the roofing before it reaches the embossing roller. This heating means may be located below the roofin I as shown, or above it or both above an below. I is a roll of mineral surfaced roofing which is being ornamented by my im proved apparatus and method. J is a tank or receptacle which contains a suitable liquid, or other material, preferably cool- .or cold water so that as the foundation roll B rotates in the direction of the arrowit ing operation for the purpose of cooling immerses itself in the water and receives a very light film which it carries up and imparts in part or in whole to the under surface of the roofing simultaneously with the embossing roll treating the opposite surface of the roofing to the ornamenting process. K is a pipe or other inlet from any suitable source of supply, for the receptacle J, having located near the receptacle a valve to control the amount of liquid or other film coating material that enters the receptacle. L is an outlet from the recep-- tacle J having likewise a suitable valve in it to control the amount of film coatingmaterial'that is passing out of the receptacle other than the amount which is carried out by the rotation of the foundation roll B.

In practice I prefer to use cool or cold water as the film coating material although oil or any other suitable material that will not destroy or effect the under side of the roofing is satisfactory for this purpose. In the use of cool or cold water or other suitable liquid the film, on the foundation roll B, acts to cool the under side of the roofing and prevents its adherence to the foundation roll, while the embossing operation is being performed. In using water or a similar liquid to keep it at an even temperature,

or to constantly have a supply of cleanliquid, if desired a continuous flow into and out of the receptacle J may be maintained. It is desirable in the orna-menting of the mineralsurfaced roofing that the cooling of the under side of the roofin extend not beyond the saturated felt; in other words that the cooling prior to or at the time the embossing operation is performed in no way chills or cools the coating material as thedecorating or ornamenting of the roofing depends upon the readjustment of the plastic coating material in predetermined areas to permit and facilitate the mineral surfacing being pressed into and completely covered by t e coating. f

My improved. method ,of manufacture using the apparatus shown is to take a complete roll of marketable mineral surfaced roofing, subject it to heating process'andf then pass it between two rolls, one of which has a design on itthe design lines being heated and the under roll having a film of water on it which contacts with the under surface of the roofing, simultaneously with the embossing roll contacting withthe upper surface of the roofing, thereby preven ng adherence of the roofing to the foundation roll, cooling the roofing on its under surface which permits increase of speed of the operation of the rolls thus facilitating the speed of ornamenting. The liquid film not only acts to prevent the adherence of the roofing to the foundation roller B, but also tendsto cool the under surface of the roofing without affecting the temperature of the coating material which has been softened by the preheating operation. After the em bossing operation the roofing is then passed around suitable cooling rolls which act to cool the same from the upper'surface.

In practice I have found that my improved apparatus and method greatly facilita-te the speed of operation of the ornamenting of the roofing while overcoming many of the objections which have heretofore existed in the manufacture of mineral surfaced ornamental roofing.

In apparatus for ornamenting roofing of the character described, a-heated embossing element for forcing the mineral surfacing into the roofingco'ating, a supporting element for the roofing arranged adja-V cent to said embossing element, and means for imparting a liquid film to said supporting element. 7

containing receptacle in which the said rotating supporting element rotates.

3. In apparatus for ornamenting roof-- ing of the character described, a heated embossing element for forcing the mineral surfacing into the roofing coating, a
