Description

UNITED STATES PATENT OFFICE.
ARMY GEIPEL, OF PLAUEN IN VOGTLAND, GERMANY.
PROCESS FOR MANUFACTURING PLASTIC MASS.
Specification of Letters Patent.
Patented Sept. 26, 1905.
Application filed July 5, 1904:. Serial No. 215,375- (Specimena) To all whom it may concern:
Be it known that I, ARMY GEIPEL, a factory engineer, and a subject of the King of Saxony, residing in the city of Plauen in Vogtland, Kingdom of Saxony, and German Empire, have invented a certain new and useful Process for Manufacturing a Plastic Mass, of which the following is a specification.
The invention has reference to a process for manufacturing a substance which may assume any desired shape by casting and subsequent drying and hardened to such an extent that it may be employed for manufacturing objects of daily use of different kind, such as buttons and the like.
The process consists in the treatment with alkali of the bast or inner bark of the calabash or monkey-bread tree, Which abounds in Africa. This treatment with alkali is effected, preferably, by heating and boiling. This causes a pulp-like substance to separate from the bast. This pulp-like substance is separated from the bast or inner barkby Washing the same and is then retained on filters. The
wet paste-like mass obtained can be cast and pressed to any possible shape and it then becomes hard and resistant in drying. It may therefore be employed for manufacturing objects of daily use of any kind. Thus by the process described there may be manufactured, for instance, buttons, electrical supplies, calender-rollers, pulleys, handles for I tools, floor-coverings, Wall-coverings, pedestals, and the like.
What I claim, and desire to secure by Letters Patent of the United States, is
1. The process of manufacturing a hard and resistant mass, which consists in separating the pulp-like mass resulting from the treatment of the bast of the monkey-bread tree (Adrmsom'a L) and similar plants with alkali, preferably at an elevated. temperature, from the fibers of the bast by Washing, pressing the mass into any desired shape and drying the same; substantially as described.
2. As a new composition of matter. a dry and resisting mass composed of the cellular pulp-like mass of the bast of the monkeybread tree and similar plants; substantially as described.
In Witness whereof I have hereunto signed my name in the presence of tWo subscribing Witnesses.
ARMY GEIPEL.
