Description
UNITED STATES PATENT OFFICE.
ERNST OTTO GRT INERT, OF MEISSEN, SAXONY, GERMANY.
MANUFACTURE OF LINOPHANIES OR TRANSLUC'ENT PICTURES.
SPECIFICATION forming part of Letters Patent No. 314,931, dated March 31, 1885.
Application filed December 3, 1884. (No specimens.)
To aZZ whom it may concern.-
Be it known that I, ERNST OTTo GRUNERT, of Meissen, in the Kingdom of Saxony and German Empire, have invented certain Improvements in the Manufacture of Linopha- :uies or Translucent Pictures, Ornaments, &c., from Paper-Pulp, of which the following is a specification.
My new method of making linophanics, so called, comprises the following steps: Paper-pulp, white or colored, in a liquid or semi-liquid state, is poured into a mold, usually of metal, the bottom of which is engraved to form or produce the desired design or picture. Enough pulp must be poured in to leave athin film of paper over the highest -lines of the engraved surface, when the pulp other similar material that will not adhere to the pulp, but will permit the passage of water, and on this I place blotting paper in one or more layers, and then subject the whole to pressure in any ordinary press. The blottingpaper is thus caused to absorb the greater portion of the water from the pulp, and the latter is pressed into allthe finer-lines of the engraving and suitably compacted. For the blotting-paper I may substitute any other similar absorbent material--as some kinds of felt, for example. After removing the mold from the press I remove the blotting-paper and the linen or gauze separating material, and then, by preference, subjectthe mold containing the partially-dried pulp to artificial heat, as in a stove or kiln, to dry out the remaining moisture. The dried paperpulp is now removed from the mold, and will be found to consist of a continuous imperferated paper leaf bearing the design or picture, which will be fully brought out when the sheet is held up between the eye and a strong light. The thinner portions of the sheet will repre sent the lights of the picture, and the thicker (and less translucent) portions will represent the shades.
The picture or ornament thus produced is called a linophany, and maybe employed for lamp or gas shades, and for transparent pictures for windows, &c., or, indeed, for any ornamental purposes to which such a picture or design is adapted.
In lieu of using artificial heat to dry the pulp in the mold, I may allow it to dry by the natural evaporation of its moisture; but I prefer to employ a heated kiln.
The mold is usually engraved, but the design may be formed in any wayas by pressure from a hardened relief-plate, for example.
Having thus described my invention, I claim 1. The herein-described method of manufacturing linophanics, so called,whieh consists in, first, pouring paper-pulp intoa properly-prepared mold, as described; second,covering said pulp with a pervious sheet of gauze or its specified equivalent, and then placing upon said sheetblotting-paper or other similar absorbent material; third, subjecting the contents of the mold to pressure, and, fourth, removing the absorbent material and the gauze, in order that the pulp may dry in the mold, substantially as described.
2. The hereiirdescribed method of manufacturing "linophanies, so called,which consists in, first, pouring paper-pulp into aproperly-prepared mold, as described; second,covering said pulp with a pervious sheet of gauze or its specified equivalent, and then placing upon said sheet blotting-paper or other simithe mold, substantially as described.
This specification signed by me this 24th day of October, 1884.
ERNST OTTO GRI INERT.
