' METHOD OF MAKING ARTIFICIAL VARIEGATED STONE VENEER, I a

Be it known that I, J OHN TULLY, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented-certain new and useful Improvements in Methods of Making Arti- Veneer, of which the following 1s a full, clear, and exact description.

Heretofore calcareous veneer has been used employing substantially the same or equiva-' lent ingredient s used to make the body of my, improved composition. In all of these veneers, however, no attempt has been made to produce a variegated marbleiz ed appearance but simply by accident orfdesign a single color efi'ect The object of myinvention is to produce a plastic calcareous veneer aving a variegated marblei'zed appearance, in which the veinmg and intenningling of the colors is the same as in the natural stone, which when applied leaves, no defined joint, and

' which when dry is capable of receiving a coat of sizing and of varnish that imparts thereto the luster ofpolished stone. This I accomplish by an improved method of manipulating the composition of which the ve- I neer is made and which, preferably, consists of a mixture of calcareous material, such as lime, Portland cement, plaster of paris, Keen cement, or their equivalents, and asbestos fiber, linen jute, halr, talcum or other suitable fiber. Several difl'erent masses of these ingredients are mixed together. One mass I prefer to mix without any coloring matter, but to each of the other masses I add the coloring matter necessary to impart thereto have. rately subject to a thorough pounding or the distinctive color it is desired each should Each of these masses I then sepakneading, or squeezing, until each is reduced to a thoroughly distributed homogeneous plastic mass, and where colored, until the color is evenly difl'used throughout. I then sire toconstitute the body of the marbleized effect. I want to-produce, say white, or that mass to which no coloring matter was added and roll. 1t out into a very thin sheet, and then take a smaller portion of one of the other masses, say blue, and placing it u on .the thinly rolled sheet of the bodyniass, old

the edges of the latter over the former, and

then roll the combined masses out into a thin sheet again. I then fold the edges of this Specification of Letters Patent. Application filed larch so, 1900: saw No. 308,910.

last rolled sheet of the combined masses over again, and so on again and again, until I obtain'the desired distribution of the blue mass through the white mass, with the blue streaksand veins shot all throughout the white, similar to the veining of the natural-stone it is desired to imitate, and then I roll the mass out into a very thin veneer and out the latter. into the shape desired to cover the object to which it is desired-to apply the same. When folding over the edges I of the rolled masses, during the process of reducing it I fold over the edges in a different manner each time and if desired I can roll .the sheet instead of folding over the same so as to produce certain efiects.

It is preferred to apply a suitable sizing i to the wall or objectto which my improved veneer is to be applied in order to, make it adhere thereto. ..I prefer this sizing to consist of lime, soluble silicate and fossil meal, or

glue and alum, or gelatin and silicate of soda.

Upon such sizing the thin sheets of veneer, while yet in a plastic condition, are applied in such manner that the edges of each sheet will slightly overlap the edges of the adjoining sheet, and then the edges are rolled until the seam between the two has entirely disappeared. This gives a continuous marbleized appearance to the wall or object to which my improved veneer is applied, and when the latter has set, or dried, it can be sized and varnished and thus given a luster like unto polished stone.

Either vegetable or mineral'coloring mat ter may be employed in making the above composition. I prefer, however, to employ powdered colored glass, because of the permanency and brilliancy of the color.

' What I claim as new is 1. The method of manufacturing imitation s'tone veneer consisting, first, in mixing a plastic composition and separatin the same into independent masses; secon impregnating several of said masses each with a separate color ingredient; third, rolling one or more of said colored masses with one or more uncolored masses; fourth, folding and rollin said intermixed mass several tlmes; and fth, compressing the resultant mass into thin sheets.

2. The method of manufacturing imita- 'tlon stone veneer consisting, first, in mixing a plastic composition and separatln the same into independent masses; secon .im-

pregnating several ofsaidmasses each with a separate color ingredient composed of pulverized glass; third, rolling one or more of said colored masses with one or'more uncolored masses; fourth, folding and rolling said intermixed mass several times; and fifth, compressing the resultant mass into thin sheets.

In testimony whereof I have hereunto 20 set my hand and seal this 21st day of March,
