SPECIFICATION forming part of Letters 1atent No. 281,721, dated July 24, 1883.

- 'Application filed May 12,1883. (No specimens.) I

To all whom it may concern:

- York, in the county and State of New York,

have invented an Improved Composition for an Under-Ground for Paint or Oalcimine, of which the following is a specification.

This invention relates to a new composition of ingredients for producing a liquid with which wood or other matter that isto be painted or calcimined is first to be covered, so as to make numerous coats -of paint or calcimine unnecessary. The composition is of such a character that it will fill the pores of the wood or other body to be painted,'and that it will prevent the oil-paint or calcimine from soaking into the surface, so that, in fact, one coat of paint will, when placed on thisv composition, have as good an effect as two coats of paint that are-directlyplaced in the ordinary manner upon the naked surface. of the wood or My composition consists of the following in gredients, that are mixed in about the proportions stated, to wit: slippery-elm, five ounces; flax'seed, three ounces vegetable oil, twenty drops; nitric acid, forty drops; alum, three ounces; glycerine, three drops; water, one gal- 1011. The said ingredients are mixed in the following manner, to wit: The slipp ery-elm and the fiaxseed are first placed intoa vessel and boiling water is poured on them. The mixmiXed in a suitable vessel with all the other ingredients named. This completes the composition, which is then, with a brush, applied to the surface of the wood or wall. The composition will form a film by which the soaking into the wood or other body of paint or calcimine or varnish is prevented. The composition also fills the pores of the wood or Wall, so as to prevent the paint from being absorbed by said pores. Being colorless, the Beitknown that I, RICHARD PARKE, of New composition leaves to the wood or wall its original color; but when the woodor wall is to be painted insome particular tint, a corresponding water-color-that is, colorsoluble in 'watermay be added to the. composition, so

that the natural color of the wood or wall will be already concealed by the composition itself, which will then add to the effect of the paint or calcim ine afterward applied.

The slippery-elm and the flaxseed are used because of their fibrous constituents; and instead of slippery-elm a correspondingly larger quantity of fiaxseed may be used; or instead of flaxseed a-correspondingly greater proporprefer to use the slippery-elm and the fla-Xseed together in about the proportions named, because the slippery elm has more fiber, and'is therefore better, than the fiaxseed alone would be, while the fiaxseed, being'cheaper than the slippery-elm, makes the mixture less expensive. The vegetable oil, which may be raw 'linseed-oihadds to the body of the composition, while the nitric acid holds the oil so that it will not fioat on the water. The glycerine will prevent the'composition, after it is applied by the'brush, from drying too rapidly, so that in covering large surfaces blots will not be formed by the wet matter coming on the edges of spots already dried; but when to be used for covering small surfaces the glycerine .may be omitted.

'tion of the slippery-elm may be used; but I
