IMPROVEMENT IN METHODS OF AIPLYING METALLIC POWDERS TO WALL AND FLOOR COVERINGS.
Specification forming part of Letters Patent No. 218,102, dated July 29, 1879; application filed February 3, 1879.
To all whom it may concern:
Be it known that we, AUGUST WOHLFARTH and GoNsTANTIN GARTENFELD, of Leipsic, in the German Empire, have invented a new 7 and useful Improvement in the Method of Applying Metallic Powders to Wall and Floor Goverin gs, which is set forth and described in the following specification.
The gold and silver patterns or designs of paper-hangings, tapestry, oil-cloth, and wall and floor coverings in general have commonly, until the present time, been produced by impressing the design upon the paper or cloth with a thick varnish of linseed-oil or other glutinous substance, and then covering it with leaf-gold or leaf-silver, or strewin g thereon bronze-powder. This process is objectionable, because a surface-coating of gold or silver leaf, or bronze-powder is liable to wear or rub 0d, and it also necessitates the use of a large quantity of the aforesaid material, thus makin g the ordinary wall and floor coverings with bronze and gold and silver patterns expensive articles.
We are aware of the fact that it has been proposed to print a colorless and concentrated ,.;scribes the admixture of silicate of alkali with 7 metallic pigments and various Tiigeral and dther colorsffor producing materials for paintnfgjpnnnng, varnishing, writing, and other analogous purposes.
,4 l The present inven tionconsist s in the method of applying old silver or bronze pwtle; to wall and flogiipv'efifi'gs arid' a n a'l gous'surfaces, which consists in mixing the said powders with solublwass and imprinting the mixture upTn the said surfaces before the composition hardens, as will be hereinafter more fully described.
In carrying out our invention we take one a pri g-co or w ich, lstributed in the usual manner upon suitable printing blocks or rollers, can be transferred upon paper, oilcloth, and textures, as well as upon wood, glass, porcelain, metal, and leather. The soluble glass takes the place of the varnish or i drogen which so commonly effect the altera- 7 tion and destruction of designs produced in the ordinary manner-that is, by strewing the colors on the previously-printed design" In addition to the simplified manner of printing attained by the use of our compound, We are enabled to produce designs which may be considered perfianent or unchangeable, this feature bein g particularly desirable in connection with textile fabrics, because the latter can'be washed without detriment to the design, it being obvious, however, that boiling water must not be used.
The proportions above mentioned will give the most favorable results; but if it is deemed desirable to give a greater or less consistency to the compound or mixture, this may be accomplished by varying the amount of colorin g-matter used in connection with the waterglass.
In consequence of the rapid drying of our mixture the process of printing must be performed in an uninterrupted manner, in order to avoid the hardening of the mixture upon the distributing devices or the printing-form. In order to prevent such,..al.h. lil'lening from immediately mimigplate, the mass may be made more liquid by adding a'suitable quantity of warm water- -say ten to twenty per cent. e same result may also be obtained by the admixture of l rin'epf molasses or of a solution of su" ar 1n vater mhesetlast-menweight part of old silv o r bronze OVITdQI: and mix it with Two parts of water- Iass "s91; uble glass, or silicate of soda thus producing the said powders with soluble glass and imprinting the mixture upon the said surfaces before the composition hardens, substantially as and for the purpose set forth.
In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
AUGUST WOHLFARTH. GONSTANTIN GARTENFELD.
