IMPROVEMENT IN ROOFING-FELT.

The Schedule referred to in these Letters Patent and making part 0! the samr To all whom it may concern Be it known that I,\V[LLIA.\[ l3. COATES, of the city of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Roofing-Felts; and I do hereby declare the-following t-o-be a full, clear, and exact description of the same.

The object of my invention is to make the various roofing-felts now known more valuable and better adapted to the purpose of turning rain or snow-water than they proved to be in actual use, and to make them superior non-comluctors of heat.

The nature of myinveution consists in applying a properly-prepared sizing to the upper and lower sides .and edges of roofing-felts, and, after it dries, a coat of some good carbon paint, with as much fine dry sand spriuklcdover the paint as the latter, will hold; also, a wash of. lime, white or colored, with pigments to suit the'fancy, prepared so as not to rcadil y come oii, to be put on after the sand is perfectly dry.

Il'iOIdel' toenable others skilled in the art to make and use any invention I will proceed to. describe the same. I

The oonnnou fcltings are h 'Jle to become rough and somewhat flimsy from frequent handling and transportation, and-this rough usage leads to a partial separation of the fibers composing the material, and occasions a tendency to leak when put on roofs that are unusually flat, and even when painted are not generally deprived of their objectionable feature. {There are large numbers of personswho would like to use the felts for roofing, if assured tbattthoy could rely upon them to turn snow-water and be of satisfactory utility.

After repeated experiments I have proved that the felts can be much improved and rendered next to slate, double-cross tin; or cedar shingles, in durability.

The manner of accomplishing this will depend, somewhat, upon the quality of the felts and the jlu gment of those who may carry out my ideas.

Though the success of my invention does not exactly depend upon a perfectly correct proportion of ingredients in the sizing, or the thickness of the coats of paint and sand or washes, yet, to prevent any misunderstanding, I will be exact in my description in regard to the requisite details of preparation and the manner of accomplishing my purposes;

The felting is first carefully examined, as none but good and perfect goods should be used, and is then ready for sizin g This can be done in small quantities, by hand, and using a wide brush or in large quantities, by macbinery.

The main object of sizing is to keep the paint on the surface and act as a base for other coats; wit-hont it the paints sink into the feltings and seem to disappear. v

I make the sizing of wheat or rye flour and water, in the proportion of one quarter of a pound, inoreor less, of wheat or rye flour to one gallon of water, and it sliouldboil, wlthout burning, for ten minutes; when done, strain it through a coarse bag.

Next, take one-half ounce, more or less, of good glue, and boil it in one quart of water for fifteen minutes,strain it, and mix well with the boiled flour or rye.

They can be prepared iu lukewarm or cold water to answer as well, but the glue should remain till dissolved, and the wheat or rye flour, ten minutes.

' In these proportions, and in either manner, any

quantity of sizing can be made.

The felts are run through the sizing by means of proper machinery, quite rapidly, so as not 'to absorb too large a quantity, and are then dried.

lfa small lot of felting is required, the sizing can be put on with ahaml-brnsh.

In covering the felting with a coat of paint a handbrush can be used for. small lots or machinery for large qnantitcs.

The machinery used is quite simple, consisting of a. vat with a sliding roller near the lower part, inside, and two gummed rollers .atthe top.

One end of the felting is put under the lower roller and brought up through the top rollers.

The sizing is put in a vat of this construction, the paint in a second,- and the washes in others. Each rat is half filled.

'Ihc felts are made in one continuous piece by soouring them at the ends, and are forced through each preparation by turning the two rollers; first, theycan be sized and dried, then run through the paint, brought over a fourth roller \vithinra box, where they are sprinkled well on every part with fine sand, and when dry, can have a second coat, or more, of paint and sand, or run through the third vat, and finished with-whitewash or fancy ,washes.

I propose and intend running the felts, after being covered with either of the above washes and dried, through a preparation, as follows:

'lwo ounces of white giue, dissolved in warm water, say one gallon, and half a pound of white flour, mixed raw, in one gallon of water, strained, to hold or fix the washes.

The whitewash is made by slakiug lime in the proportion of one quarter of a peck to a bucket of warm water, strain it, and mix in it the following prepara-- tion: glue, half an ounce, more or less, dissolved in" a quart of warm 'water, stir in the glue-water one ounce, more or less, of raw wheat flour, and, i-ffaney colors are desired, use various pigments.

As soon as the wash is dry, the prepared felts can he rolled-in long or shortpieces, at pleasure, bound in wrappers, and is then ready for sale and use.

By these varions.coats. the ordinary felts are protected and strengthened, and rendered not only more lasting, but proof against all sparks or coals of fire.

The coats fill up all the small holes in the felts and transform them into an external mineral substance better able to resist snow-water and frost. They are rendered a better non-oomluetor of heat, while the white or othercolored washgives the roofs a more vbeautiful appearance.

Another-advantage is that all dirt arising'froin the wo kmen tracking paintfrom the roofs down through a tidy house is entirely prevented.

The-price. at which this improved felting can be furnished wilt be less than the present cost of twice painting the felts when on the roofs.

The felts are put on roofs with a lap of two inches at the joints.

I do not desire, at present, to claim the machinery IshalLnse in preparing the roofing-felts.

What I claim as my invention, and desire to secure by Letters Patent, is-- The preparation of rooting-felts by the process of sizing, carbon painting, sanding, white or color wash- .ing, aud fixingthe washes, as fully set forth and deseribed in the foregoingspecitication, as a new article of manufiicture'.
