• My illlDIOVGll'iGlltS in rendering silk, cotton, woolen, linen and other fabrics water-proof consists in an improved mode, manner, or method of rendering such fabrics water-proof, and is effectedby using drying-oils and oil compositions, varnishes, or other suitable composition for this purpose in such a way that one side of the fabric, when finished; presents an appearance unimpaired or but little altered by the process of waterproofing, and therefore keeps its original appearance, or nearly so, and this 1 effect by applying siccative or drying oilsand compositions in such a manner that when finished the appearance of one side only of the texture is altered-that is to say, the oil or paint or water-proof composition coats or covers the one side, while it does not cover or injure the appearance of the other side, or but little so.
• drying-oils and oil-paints and oiltvarnishes to textures is to spread or cover the surface of the fabric with a thick or stifi' coating of material, as a mixture of drying-oils, metallic oxides, and lamp-black or ochcr, or other pig'- mentor suitable body, and which is employed chiefly in the process of making floor-cloth, table-baize, cart-covers, &c.
• Another method is to mix'gelatine or other extraneous matters with the oil or varnishes, so as to remove its staining and percolating properties at the time of applying the same to the textures; but these means are imperfect, for if stiff color is used and spread on one side the more fluid portions of the mixture are withdrawn and dry in stains on the other side of the textures, after themannor in which elaine will leave the stearine on pressing fat suet between bibulous; paper;

• This process may be repeated it the membranous, stralum orpellicl'e left on the one side is not quite water-proofby the first operation; or the said watcrprobfcoatingmay be' thickened or strengthened atterward, if thought desirable, by repeated 'coats of paint, oil, varnish, or other eompositionslaid on by abrushor other i m raiis.'"*- I wislii't therefore to be understood that I what I consider my claim to these improvements "in render'i'ngfabri'cs waters-proof is the saturating woven" fabrics and fibrous textures with siccative' oils, oil-paints, oil-japans, oilvarnishes,"and other suitable compositions and -the”drying the same thereon as a coating or coveringor pellicle on one side of the textures only by various methods to be hereinafter explained',at"ihe”sametime keeping the other sidefirraiiy undried state, andthen

• This pellicle I have found by experiment is very thin for several days. I determined to applyth'is'efi'ect of nature to the waterproofing of teirturc'or fabrics in the following way:
• the upper surface was perfectly dry or hardened and coated with a thin pellicle'or film of the oil.
• Another method or modification of process of carrying my improvementsinto efi'ect is as follows-via, by merely laying the v saturated fabric on a slab of slate or stone or metal or -othersurface or material non-absorbent to oils or such matters; and this loonsidera more sini pie and convenient; method of effecting the olijects of my improvements,
• the non-absorbent surfaces I prefer to use are tables of suflicient length and breadth for the fabric intended to 'bc waterproofed, and maybe made of wood and rendered non-ab"- sorbent by coating them with thin glue or varnish or other suitable material, and when this coating is dry and hard and seasoned I take the waterproofing com positionthat is, oilor oil-paint or other suitable matters-and with a brush cover the table evenly with a coating of the waterproofing composition about. as thick as a painter generally covers a wall or partition with oil-paint. I then take thefabric (it' being previously coiled on a. roller or,
• the time required for drying, obtaining the pellicle surface or thin coating or covering depends on the nature of the oil by pins stuck through the g or rather for compositions or waterproofing material employed. In summer temperature the ordinary boiled linseed-oil takes about ten hours; but this may be ascertained by touching the surface with the finger from time to time, the drying process being continued until the outer surface of the material used loses its tackiness or adhesiveness, or, in other words, .until the pellicle is properly obtained.
• Another variation of the mode or method of carrying my invention or improvementsim to effect is to strain two pieces of fabric-on a stretching-frame such as is com monlyused by calico-printers and cloth-dressers,- so that two of their surfaces are placed evenlyand closely in contact together, and I then saturate or paint them with oil orotherwaterprooting material while in that position. I place the frame horizontally if a thin drying-oil composition or material is used, and if the material is of snmcient consistence toprevent its running to the edges or endsittmay be placed perpendicularly. By this method of operation the upper and under or the outer sides will become dry orhardened, while the.
• the object of my invention being to prevent the oil or other siccat-ive composition drying on both sides of the fabric, I shall describe anher way of effecting it-viz.,bystrainingcut the silk or fabric singly on or in aframe, then perfectly saturating it with any dryingoil or paint or other such waterproofingcomposition, and when it is beginning to set or harden on both sides-that is, when the pell'icle is'jnst formed and is yet extremely tender-I scrape the oil or composition from one side-without disturbing, the pellicle so formed on the other, and give the scraped side a new coating of oil:
• this latter coating is to be of suflicient thickness to protect it-that is, the-composition or inspissated oil firstapplied-from the action of the air; andwhcn the other or reverse side of the fabric 'isdry, or the pelliclc surface sufficiently formed, then these two coatings of materials on the one or protected side. may be removed by cleansing the surface with it spirits of turpentine,- as before stated.
• Bythesc means one side-will be caused to dry before the other, and-thus I am enabled to preserve the other side und-ried, so as to be washed, as before.
• Another method which may be employed is to thicken or inspissate the d-ryiug-oilwith lampblack or, other suitable substance, so as to bring. it to abnttery consistence, and thenapplyit to the fabrics on each side, butwith coat ings of unequal thickness, which may bedonc by a brush orother means in such manner-that no more than is intended to form the.
• perma nent coating shall be laid on one side, while the other or temporary coating is laid on sufficiently thick that, although itskinsoverorforms a pellicle on its outer surface, yet itsunder or within stratum is not dry, and therefore this temporary coating may be readily scraped off,
• dryin g or hardening property for the purpose of saturating the texture, in the first place, and then by artificial-means to cover one side of the texture, so that this side shall remain nudried while the other dries, hardens, or, in other words, has a .pelliclc formed on that surface which is exposed to the direct action of the air or artificial heat, and whichpellicle is firmly incorporated with or attached to that surface, the other side being protected from the action of the air or heat, which enables the moist part or coating to be cleared away, so as to leave the texture in its original appearance or its surface unimpaired, or nearly so.
• Another modification of producing the same effect is by using perforated pattern plates and boards, hardened oil-cloth, or other suitable laminated material, and placing the same against one side only of the fabric, or between two surfaces of silk or other texture stretched on a frame, as before named.
