UNITED STATES PATENT EEICE.
ROBERT KRAFFT,'OF CARLSRUHE, GERMANY TURF MATRIX-PULP FOR STEREOTYPING.
SPECIFICATION forming part of Letters Patent No. 698,028, dated April 22, 1902. Application filed May 6, 1901. Serial No. 58,924. (No specimens.)
To aZZ whom it may concern:
Be it known that I, ROBERT KRAFFT, papermaker, a citizen of the German Empire, residing at Uhlandstrasse 5, in the city of Carlsruhe, Grand Duchy of Baden, Germany, have invented a new and useful Improvement in Stereotyping,of which the followingis a specification. V
My invention relates to the production of suitable dry or quick stereotype-plates for the printing industry and allied branches. The matrix-plates hitherto used for this purpose very soon become hard, whereby the type even in a short time gets extraordinarily worn, and to remain even-in some degree fit for use must be continually keptmoist. Besides,the production of the matrix as far as to the casting of the plates depends on a cumbersome process, causing loss of time to an extent approaching a full half-hour.
The subject of my invention is the discovcry of a suitable composition for a matrixpulp with which the advantage accrues that after the very first casting from this turf matrix-pulp its interior components main tain such a capacity of resistance that successively any number of casts may be taken without damaging the matrix in the least.
The invention consists in the arrangement of an intermediate pulp layerof such a character that it causes the type to. be sharply impressed, that the required pliancy is retained, and that mold or mildew is entirely prevented, while by means of a suitable agglutinant all its parts firmly cohere.
The pulp as a whole is composed of three parts"vii., the under layer, the intermediate layer, and the top layer. While the under layer can consist of any paper-pulp and the top layer is also of such material, which may advantageously be made of two-thirds cotton and one-third linen in an unsized condition, (sized stuff being also employed for particular objects,) the intermediate layer is in this connection of especial importance. Such intermediate layer consists of about fifty-five to sixty per cent. of finely-ground turf with an addition of some ten per cent. of glycerimten per cent. of starch, and twenty to twenty-five per cent. of paper-pulp,- which composition has further an admixture of about 0.5 per cent. of carbolic acid or some other antiseptic.
type shall be sharply impressed. The glycerin by promoting moisture insures the continuous pliancy requisite. The starch acts as a binding material, and the slight per centageof carbolic acid or the like prevents formation of mold or mildew. It may be again pointed out that the choice is preferable of two-thirds cotton and one-third linen for paper-pulp; but, however, further admixture is allowable of another fibrous material which may tend, as does the paper-pulp, to impart somewhat more consistency to the fine turf fibers in forming this intermediate layer. These plates can be produced as easily by hand as by machine. in the method with hand-made paper and dipping, the under layer is prepared, then, similarly, the intermediate layer, and thus, last, the top layer, orrthe process may be reversed, the top layer being prepared first, and so on. various layers are pressed in a moist condi tion and dried by being hung between clamp ing-plates, as in'the manufacture of handmade paper, or in large quantities on drying cylinders, and finally, if it be'considered desirable, the surface of the top layer may as well be glossed in the ordinary manner. By wholesale or continuously produced the pulp is prepared on machineshaving several cylinders or other machines on which paper or' pasteboard with various layers is worked-as, for example, machines for sugar-paper. That the type shall not be pressed through, the
In the first place, as
These plates thus obtained of the union of the three different layers, especially after the plate is cast the pricking out of such spaces. After ensuing trimming of the four edges these plates can be immediately handed over to the printer and put in use. Be
sides the advantages described and others not starch, paper-pulp and a small percentage of mentioned here these turf matrices can be an antiseptic, such as carbolic acid, substansupplied at a low cost, which confers an additional benefit on the industry concerned.
WVhat I claim as my invention, and desire to secure by Letters Patent of the United States, is-
As a new article of manufacture, a matrixsheet comprising an inner and outer layer and an intermediate layer of pulp composed of a mixture of finelyground turf, glycerin,
tially as described.
In testimony whereof I have signed my 15 name to this specification in the presence of two subscribing Witnesses.
ROBERT KRAFFT.
