PROCESS 0F MANUFACTURING CHAIR-SEATS OFV VEGETABLE FIBER AND CHROMIC ACID.
SPECIFICATION forming part of Letters YPatentNo. 297,639, dated April 29, 1884:.
' appneauonmeanrays,1883. (Model.)
To all whom it may concern.-
Be it known that I, RUDOLF ScHIMMEn a citizen of Germany and a resident of Anna# berg, in Germany, have invented a new and Improved Ohair-Seat, of which the following is a specication.
Figures 1 and 2l are perspective viewsof the product; Fig. 3, a cross-section. Fig. 4L represents a side view of compressingl device.
The nature of my invention consists of a mixture of pulp of ground rags and vegetable fiber,in equal parts,and chromic acid,made in a thick mass or paste, from which sheets of the required shape and design areformed for cov ering the seats and backs of chairs and similar articles of furniture, as a substitute for cane or Wood seats. The vegetable bers, preferably of wood, and the ground rags are worked and mixed in a pulping-engine, with the addition of chromic acid, three parts to one hundred parts of water, and this thick mass or paste is then formed into sheets of the required size and thickness. The thus-formed sheets may be strengthened by the addition of a' textile material of linen, cotton. or any other material placed-in the central part of the sheet. The sheet, after being cut in/the desired size and shape, is then placed between two plates, C D, of which the lower plate, D, has astraight surface, and the upper plate, C, has the design or pattern engraved or cut on its surface,
l which is desired to b given to the sheeeand is likewise provided with projecting pins to perforate the sheet. These plates C'D, with the sheet betweenthem, are then passed be- -tween pressure-rollers .E F, vwhereby the desired configuration is given to the surface-of the sheet, as shown in Figs.`l and 2, or of any other desired design. The thus molded and pressed sheet is then varnished,to protect the strengthening these sheets by the addition of textile fabric; then molding and pressing each sheet to give the proper texture and supercial configuration; the-varnishing and drying each sheet and cutting the chair-seats out of the same.
RUDOLF SGHIMMEL.
