Description
Patented Nov. 12, 1929 UNITED STATES mmr. 1n. rnosr,.or curse, urcnrem raonuc'rrou or rmnn m'rrcnns No Drawing. Application filed August 20, 1927, Serial No. 214,438. Renewed Kay 1, 1928.
The present invention relates to the production of articles of compressed fibrous materials and particularly of a process of producing such articles and the articles pro-' 5 duced thereby.
Among the objects of the invention is an article of manufacture which is extremely compact, tough, Waterproof and capable of taking an excellent finish.
Other objects will readily appear to those skilled in the art upon reference to the following description.
Heretofore, such articles of manufacture as chair or toilet seats, doors, boxes and the like have been usually made of wood pieces glued or otherw'se secured together. \Vood has been considered the only suitable material because of its plentifulness and also be-' causeof its low head conductivity. However, due to its property of absorbing moisture, it is ditficult if not impossible to build up anarticle, such as a toilet seat, from pieces of wood glued together and have the piece adhere permanently.
The present process produces an article that is not built up of pieces but is of homo-- geneous composition, waterproof and has all of the advantageous properties of wood.
The process is carried out by firstforming a fluent pulp of fibrous material, such as ground wood pulp or pulp of rag fiber, wastepaper, hemp, jute or even asbestos. To this pulp having preferably from four to twenty per cent solids is added rosin soap up to fifty per cent of the total solids. This mixture is agitated thoroughly and pumped into suitable dies where the water is expressed therefrom and the article formed under a pressure depending on the article to be proinch. he formed article is then removed from the die and dried and rough finished if necessary.
After the drying steps dipped in a solution of the article is then andallowed to remain a ort time, say from three to ten minutes or longer it necessar to allow the said solution which is quite aid to impregnate to some extent, after which duced u to six hundred pounds per square preferably sixty per.
cent pine 'oil and forty percent banana oila hard tough-body of finely methods such as are used to impregnate other porous materials may be used. Such methods consist in submerging the article in the impregnating liquid in a closed vessel-and subjecting the liquid to high pressure or in first exhausting and then subjecting to pressure. This pine oil and banana oil impregnation and superficial coating renders the compressed fiber article waterpoof and thereis thus produced one that is strong and sub stantially permanent.
Now having described the invention and the preferred form of embodiment thereof it is to be understood that the said invention I is to be limited not to the specific details herein set forth only by the scope of the claims which follow.
I claim: 4 1.. The process of producinghomogenous fiber articles which consists in forming a pul of the fiber in finely divided conditions so wit water, mixing with said pulp rosin soap,
expressing said water therefrom under high pressure drying and subjecting the molded article to an impregnation treatment with a solution of pineoil and banana oil. v
2. The process of producing homogenous fiber article which consists in forming a pulp of the fiber in finely divided conditions with water, mixing with said pulp rosin soap expressing-said water therefrom under a pressure of up to sixhundred pounds pers uare inch, drying and subjecting the molde ar ticle toan impregnation treatment with a solution of pine oil and banana oil. 7
3. An article of manufacture comprising divided organic. fiber and rosin soap with a coatin and at least avsuperficial impregnation with a solution of pine oil and banana oil.
