ROOFING FABRIC.

SPECIFICATION forming part of meters Patent No.385.057. dated June 26, 1888.

Application filed July 28, 1887. SeriaLNo. 245,550. (No model.)

To'all whom it may concern: 7

Be it known that I, ALEXANDER JoNEs, of

Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Roofing Fabrics, of

which the following is a specification.

My invention has reference to an improved roofing material; and it consists in a novel construction of the same, as hereinafter set forth 10 and claimed.

In the drawings I have shown a perspective view of the apparatus by means of which the roofing material is made; but although I have described the said apparatus in detail herein :5 I reserve to myself the right to make it the subj act-matter of a separate application.

I will first describe the apparatus employed and then the materials and their mode of application by means of said apparatus.

A indicates atank or vat, of iron or other suitable "material, beneath which is a .fi're-f space, B, preferably provided with a grate upon which to place fuel. This tank is desighed to-contain a mixture or preparation with which to saturate cotton goods or other fabric, of which the roofing material in part consists. Near the bottom of the tank or vat is a bar, 0, which may convenientlybe carried by a frame, D, running in guides inthe 0 ends of the tank or. vat, said bar serving to press down and hold beneath the surface of the contents of chamber the web or sheet E of fabric to be treated.

F indicates a bar parallel with the bar G,

located at or near the top of the tank or vat A and directly over the same, said bar serv= ing as a scraper to remove the surplus mate-- rial or composition carried up by the web orfabric from the tank or vat.

G indicates a frame-work exten ing from the rear side of the tank backward a considerable distance. The portion of the framework next to and immediately in rear of the tank or vat is furnished with a close-table or 5, platform, H, upon which is placed a body of sand or equivalent material, and the remaining portion of the frame-work is formedwith, longitudinal central and side bars, I, andcross-bars J, the latter separated from each 0 other, so asto permit the air to pass freely between them. At the rear end of the framethe purpose of drawing the end of the fabric work G there is placed a box or receptacle, K,

and above and removably mounted in suitable hearings or supports is a shaft or arbor, 1., provided with a handle or wrench by which to turn it.

N indicates a hopper or box to contain sand or like material, and provided at its bottom with a feed-roller, 0, or equivalent means for causing a uniform discharge of material from the hopper upon the web or fabric passing beneath it.

P indicates a bar provided with books a, upon which to hook the fabric, and Qindicates a rope or band extending from a bridle, 6, attached to the ends of the bar P to the shaft or arbor L. This bar 1? and rope or band Q are employed. onlyin beginning the treatment of a bolt or roll of fabric, and are for from the tank or vat A to the arbor or shaft L. A When this is accomplished, the first'shaft L is removed and a new vone substituted. The fabric is unhooked from the bar I and wrapped about the shaft or arbor L; and by turning the latter the material isdrawn forward and wound into a compact roll as fast as treated.

Motion may be given to the arbor 'L and feed-roll 0 from any convenient source of power,- or the shaft L may be turned by hand and the roll 0 driven by a belt, R, passing about a pulley on said roll, and a second pulley on the shaft orarbor L, the latter being conveniently formed with or attached to the wrench M, so that it may be removed from one arbor and placed on another.

Having now described my apparatus, and with the remark that it may be considerably modified as to its general structure, the pre cise form of tank and heater, sanding devices, 8.00., being susceptible of variation, 1 will pro oeed to describe the proportions or compounds employed and the mode of applying them. with the aid of the apparatus above setlforth. I first place within the tank or vat Athe following substances or materials in the proportions and usually in the quantities stated-z One hundred pounds of rosin, ten pounds of gum-shellac, five pounds of litharge, twentypouuds of rosin-oil, ten pounds of linseed-oil, and ten pounds of asp'haltu m. I then startija fire in the space Bwithin the tank or vat and produceheat snflicient to melt these substances together, stirring and ,mixingthe same to in-. sure a perfect union thereof, and I maintain a fire beneath the tank or vat while treating the fabric to. insure a proper fluidity of the composition and a thorough saturationof the fab ric; I also place upon the bed or table H and in the hopper N a supply of sand free from sticks, pebbles, or foreign matter of any kind, 4 that upon the bed or platform H being advis-r ably rounded up in'th'e middle, so as to insure a-stretchi'ngpf the fabric over it from edge. to edge anda certainty. of contact of every portionof the lower face of the fabric with sand. Having made these preparations, I provide a belt or roll of woven fabric, preferably stout cotton good s, and I carry one end thereof over the edge of the outer side of tank or vat A, holding the goods firmiyat its sides and press ingit down into the composition or preparationin the tank or vat by means ofthe crossbarG and its frame D, which should be of sufficient weight to'hold the fabric beneath the surfaceof the solution, but which shonldnot 25 be sent quite to the bottom of the tank or vat,

as in thatcase there wouldbe danger of scorching tlfefabric orof impeding its travel through the yat. By this manner of starting the material through the vet a portion -of about six or eight inches is left uncoated, thus enabling. the-attendants to draw the fabric forward over the bar F and upon the bed or table H with' out selling the hands, as would otherwise in-' evitab y occur The-un'coated portion, being 5 carried upward over the bar F and to the upper side of the bed or platformH, is hooked upou'the hook'sor teeth a of the bar 1?, and the rope or band L attached to said bards theb wound upon the arbor or shaft L by turning the wrench M, thereby drawing forward the bar 1*,Iand with it the fabric E, which, in thus moving forward; travels over the bar F and has the surplus coating removed from it and thrown back into the-tank or vat. The saturated-fabric 'passing over the body of sand on *the'table-H becomes thoroughly and evenly coated-with the sand, which adheres tenacious] y totheifahric, owing to thestickinessof the composition, while at the same time the upper s'urfaee is'similarly coated with sand by reason .of.a discharge of a constantand uniform stream through the enter esd'under the action of the I roller 0, driven by .the band Rfrom the pul l'ey c of arbor L. As the fabric p from g-y-the sand-covered table or platform H, it enters upon the open rear portion of the frame G and is exposed to the air above and below,- the a band or rope L being supported by the central :ban, I, and. the bar P being supported by the same and the side bars, as will be readily seen." When. the bar P reaohesthe arbor'L, the fabric is nnhooked from'said bar, asecond arbor issub' stituted for the first, the unceated end of thema-L terialiis wrapped upon the fresh arbor, and the winding begins. Any surplus sand] ing upon- -prevents adhesion of the prepared fabric thereto, .andleaving the arbor in condition for immediate reuse when the material is taken scope of my invention.

'thenpper face of the fabric falls in o thc'box' K as the fabric winds upon the arbor, and the sand is thereby saved for further use, The uncoated portionfirst wound upon the arbor therefrdm; The."fra'me.is of such length that the quick drying composition applied to it becomes sufiiciently dry. to prevent, with the aid of sand applied to its faces, any adhesion of'the coils upon the shaft L, one to another. The fabricbeing thus prepared is ready for immediate applicatioi to the roof; but-previous to placing 015831116 upon the roof I prefer to cover the roof with a layer of tarred felt, tacking the prepared 1 fabric upon thesame with considerably-lapped joints, the two uniting one with the other in a'short time by reason of the cementing action of the coating 8 of the felt and of the roof. After the fabric hasbeen applied to the roof it is treated with a preparation consisting of one ehnndred pounds of Cleveland iron-cladpaint or other heady mineral paint, seventy pounds of-lino seed-oil, five poundsof litharge, ten pounds of gum-shellac, andten pounds of American zinc, this preparation being carefully mixed and applied as a paint or coating with a brush, and the surface while still freshbeing ca're- .fully coated with a layer of sand to render the same fireproof, or practically so.

The ingredients and proportions above stated are those which I have after long experim'enting determined upon as best; but I do not wish to be understood as restricting myself to the precise ingredients or propertions stated, as they maybe modified considerabl-y'without departing from the spirit and 7 Thus, with regard to the solution as applied to the fabric in .the

, tank or vat A,I may employ instead of the one. hundredpounds of resin above mentioned a like quantity of asphaltum, omitting the ten pounds of asphaltum mentioned, or, in no other words, nsing'only one hundred pounds in all. So, too, the litharge may in some cases beomitted, and a mineral oil known to the trade as mineral linseed-oil maybe substituted for the rosin-oil, or for therosinoil n and 1inseed-oil. The final coating or preparation may also be modified by employing, instead of one hundred pounds of iron clad paint fifty pounds of such paint and fifty pounds of whiting. The linseed-oil may berzo omitted, and the so-called mineral linseedoil or cotton-seed oil may be substituted. The litharge may be omitted and the quantity of zinc may be doubled, in'whicb case the shellac Y may --be omitted. r2 Pu'lvcrized brick or stone may be employed in lieu of sand, though sand is preferred as.

being cheaper and more easily applied. As

aboyelstated, however, I prefer the ingredicuts. and the'proportions first given. r 0

Anyother means 'of heating maybe employed -as, for instance, a coil or. coils of steam-pipe may be placed in the vat A, or any equivalent well-known means may be employed for heating the material. in the vat or tank.

Having thus described my invention, what I claim isit 1. The herein-described roof-covering, consisting of a layer of felt, a layer of cotton fabric saturated with a mixture of rosin, shel- 1o phaltum, coated on both faces with sand, and

a top dressing fo'l' mineral paint-, linseed-oil,

litharge, shellac, and zinc, or the described equivalents of these materials, in substantially 1 the proportions ,aboveset forth.

lac, litharge, rosin-oil, linseed-oil, and as- 2. The herein described roofing material, consisting of woven fabric saturated. with a mixture of rosin, shellac, litharge, rosin-oil, linseed-oil,and asphaltum, or their described equivalents, in substantially the proportions stated, and coated on both faces with sand or its equivalent.

In witness whereof I hereunto set my hand in the presence of two witnesses.

ALEXANDER JONES.
