Description

llnrrn Parent t rrent CHARLES HENRY VEALE, OF CORK, IRELAND.
LlTi-IOGRAPHERS TRANSFER-PAPER.
SPECIFICATION forming part of Letters Patent No. 625,524, dated May 23, 1899.
Application filed January 5,1899. Serial No. 701,248. (No specimens.)
To (all whom it mity concern:
Be it known that I CHARLES HENRY VEALE, foreman lithographer, a subject of theQueen of Great Britain, residing at 124 St. Patrick street, Cork, Ireland, have invented certain new and useful Improvements in or Relating to Lithographic Transfer-Paper and Method of Preparing a Coating for the Same, of which the following is a specification.
The object of my invention is to provide a new or improved composition or coating for paper to be used for lithographic purposes whereby any lithographic printer by a uniform method of treatment will be enabled to successfully deal with all classes of moist transfer-work by one paper adaptable to the three purposes for which such paper is requiredviz. plate to stone, stone to stone, (including crayon or grained work), and type to stone-instead of using a special paper for each process requiring different experience and treatment.
According to my invention in operating upon (for example) an average of two reams of demy paper measuring twenty-two and one-half inches by seventeen'and one-half inches with eight to nine pounds coating per ream when dry I employ the following ingredients in preparing the composition for the coating: first, six and one-half pounds of fine wheat pastry-flour boiled in twenty-four pints of water, with which, when boiled, one gill of purified earbolic acid is mixed; second, sixteen pounds of French mordant-White, barium sulfate,'and half an ounce of vermilion mixed in one pint and a half of No. 2 pure glycerin, and, third, two pounds of refined plaster-of-paris beaten up in about eight pints of water and allowed to stand over night, afterwhich I pour off and discard the surplus water standing on the surface. Six ounces of Russian glue is then added, and the mixture of glue and plaster raised to a boiling heat. The whole of the ingredients (except the flour) are then mixed and well ground. The boiled flour is then added, well mixed, and the mixture strained. The composition is then ready for coating the paper and is applied to the paper by a paper-makers enameling-machine.
The drying of the paper when coated is effected in the same way as enameled paper namely, by the heated atmosphere of the enameling-room.
The transfer-paper prepared according to the above prescription possesses the following advantages: It does not harden or deteriorate by age, it imparts tothe work in operation the qualities of added and permanent strength, it renders impossible a spread or other imperfect. results, and by the concentration in one system of treatment for all moist transfers it simplifies the whole process and gives confidence to the operator by its uniform success.
My composition differs from others principallyin the use of the French mordant-white or barium sulfate, which is perfectly insoluble, while the glycerin prevents hardening by age and sustains its keeping qualities.
I have stated the best proportions of the parts for use in this composition; but the proportions may be somewhat varied Without departing from my invention, and I do not therefore limit myself precisely to the proportions herein set forth.
WVhat I claim as new, and desire to secure by Letters Patent, is-
1. A new or improved composition or coating for lithographic transfer-paper, consisting of pastry-flour, earbolic acid, French mordant-white, Vermilion, glycerin, refined plaster-'of-paris and Russian glue, the ingredients being mixed in or about the proportions specified and prepared substantially as herein set forth.
2. As a new article of manufacture lithographic transfer paper having a coating formed of fine wheat pastry-flour, carbolic acid, French mordant-White, Vermilion, glycerin, plaster-of-paris and Russian glue, the ingredients being prepared and mixed in or about the proportions specified and applied to the paper, substantially as herein set forth.
3. The method herein described for preparing a composition or coating for lithographic transfer'paper to be used for moist transferwork of all kinds, consisting in the following treatment of ingredients in the proportions substantially as specified: first, boiling six and 0ne-half pounds of fine wheat pastry-flour with twenty-four pints of Water, and adding, when boiled, one gill of purified carbolic acid; second, mixing sixteen pounds of French morto the ground ingredients, mixing the same thoroughly and finally straining the entire composition.
In testimony whereof I have hereunto set I 5 my hand in the presence of two subscribing witnesses.
OHAELES HENRY VEALE.
