MAI\TUII:AC'1"URE OF ASPHALT R OFING.
Application filed November 24, 1919. Serial No. 340,128.
To all whom it may concern:
Be it known that I, FREDERICK C. OVER- BURY, a citizen of the United States residing at Hillsdale, in the county of iBerge'n e and State of New Jersey, have invented new and useful Improvements in the Manufacture of Asphalt Roofing, of which the following is a specification.
This invention has relation to the manufacture of prepared roofing or flooringin which paper felt is saturated or impregnated with a waterproofing compound of a bituminous or asphaltic nature having a relatively low melting-point and then coated with a layer of higher meltingpoint itch or asphalt. For use as a roofing, such s eets thus prepared are usually surfaced with crushed slate or other mineral which is applied to the asphaltic coating while the latter is still soft and plastic and is partially embedded therein by. pressure. for some purposes are thereafter cut into shingles or shingle strips or slabs of various designs.
.The present invention has for its object to apply to the under uncoated face of the sheet some such powdered material as talc, infusorial earth, powdered soapstone or slate, or their equivalents to render such under face nonadhesive and thus prevent the convolutions of a rolled sheet, or the individual shingles or strips of a ackage, from sticking together. I
In accordance with the present invention,
85 this is accomplished by making an aqueous suspension of water and the powder, and applying such mixture to the under side of the sheet in any suitable way, the subsequent evaporation of the water leaving a thin sur- 4 face or layer of the powder on the surface of the sheet. This has a further advantage in that the application of water assists in cooling the sheet and solidifying the impregnating compound contained in the pores and interstices of the sheet.
On the drawingy which shows the several instrumentalities conventionally and more or less diagrammatically, a sheet of felt is indicated at 1 and is supplied from a roll 2 as usual. The sheet is drawn through'the usual til The sheets saturating tank 3, which contains the molten low-melting-point pitch oi asphalt, and,
after passing the usual squeeze rolls 4, by which the surplus or excess compound is squeezed from the impregnated felt, so as to leave the surface of the felt dry, the
sheet passes to the rolls 5, 6, where the higher-melting-point pitch or asphalt is applied on the top surface of the sheet andthen to the rolls 7, 8. At 9 is the hopper by which the crushed slate or other mineral material is applied to the plastic to coating, and the surface layer formed there y is partially embedded in the coating by the pressure of the rolls 7 8. i The sheet is then passed over or around cooling or chilling rolls 10,11, 12, 13, 14, 15, which are supplied with a cooling or refrigerating medium in the usual way. In accordance with the resent inventlon, I cause the roll 10 to dip into a bath consisting of water in whiohis suspended some inert fine mineral powder insoluble in water,'such as previously described. This bath is contained in a tank 16 to which the aqueous suspension is delivered from a mixer 17 having an agitator 18, by a pipe 19 provided with a valve20. The roll carries t e suspension upwardly on its surface, and applies it to the under side of the sheet. The water rapidly evaporates from the sheet leaving a thin non-adhesive layer of the powder adherent to the face of the sheet. After leaving the roll 15, the sheet may be festooned and wound into a roll, or cut into strips or shingles as may be desired.
The application of the aqueous powder.
suspension to the sheet assists in cooling the sheet and partially solidifying thecontained bitumen, the subsequent evaporation of the water also furthermg such cooling. lt is evident that the powder suspension may be applied in any other suitable ways, as by sprays, brushes or the likes Bymixing the" powder or slate dust with the water, and thus applyin it, I prevent the atmosphere of the mill rom being contaminated with flying dust. The powder cakes more or less on the sheet, when the water evaporates and adheres more tightly thereto, than when it-is deposited dry on the sheet.
What I claim is the evaporation of the water leaving the In the manufacture of prepared asphalt powdered material on the. surface of the roofing, impregnating felt with a molten assheet. I o n phaltic compound, then applying to the sat- In testimony whereof I have aflixed my 5 urated sheet an inert insoluble powdered g mineral of the character of talc or slate, suspended in water, and then permitting the FREDERICK C. OVERBURX.
