UNITED STATES PATENT OFFICE.
KARL Hi FLER, OF HANOVER, GERMANY COMPOSITION OF MATTER.
No Drawing,
Specification of Letters Patent. Patented Nov, 1 4, 1911,
Application filed November 28, 1910.
Serial No. 594,528.
5 new and useful Improvements Relating to the Con'iposition of Matter, of which the following is a specification.
The object of the present invention is to provide improved means enabling printing blocks or plates, lithographic stones and the like, to he uniformly, quickly and thoroughly ground, grained and polished. The methods hitherto employed for removing old engravings and the like from the plates are comparatively slow and complicated, requiring specially constructed and expensive inachines, or the plates have been treated by hand with pumice stone and a series of washing processes which involve lllttl'l V hours .of work and cause the plates to rapidly wear away owing" to thesevere and long manipulation to which they are subjected.
The presentinvention is essentially chara terized by the use of a chemical arznnposition or mixture which, when gpplicd by means of a suitably designed grindinggraining, and polishing! apparatus, obviates the above mentioned tllr-it\(l\';ll)l2l, ft.-; and enables the plate to be uniformly and quickly to secure by Letters Patent of the United States is l. A composition for the purpose set forth, consisting of binoxalate of potassium, grinding powder, aqueously soluble coloring mat ter and saw-dust.
2. A composition for the purpose set forth, consisting of parts of binoxalate of pot'assium, 30 parts of grinding powder, 20
parts of aqueously soluble coloring matter and 20 parts of saw-dust.
In witness whereof I have signed this s 'iecitication in the presence of tvv'owvitnesses.
