Definitions
- This invention relates to a new article of manufacture, prepared from the stock of the plantain-tree, (Muse sapicnttum and Muscpwmdis iacce) which, especially in the West Indies, grows to a considerable size, and from which, by proper manipulation, a superior paper-pulp can be produced.
- the roots andleaves are first cut 01f the stock of the plant, and the stock is then run through a succession of rollers, which-are immersed in water. Between these rollers it is pressed, to have the acid and liquid matter discharged from it. A mass of long fibres is thus produced. These long fibres are put through a set of toothed washing-rollers, whereby they are torn and still better cleaned.
- the reduced fibre is then immersed in a bath of chloride of lime, mixed with hot water and taltam'c acid,
Description
Write! fictive (:10, F I'IZGERALD, OF PHGENIX, NEW YORK.
- Letters Patent No. 85,07 9, dated December 22, 1868.
IMPROVED PAPER PU'LP.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Be it known that I, O. O. FITZGERALD, of'Phocnix, in the county of Os'wego, and State of New York, have invented a new and improved Paper-Pnlp aud I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to understand the same.
This invention relates to a new article of manufacture, prepared from the stock of the plantain-tree, (Muse sapicnttum and Muscpwmdis iacce) which, especially in the West Indies, grows to a considerable size, and from which, by proper manipulation, a superior paper-pulp can be produced. v
I- will now proceed to describe one method of preparing the stock, so as to produce the pulp, reserving, however, the right to produce the'same by any other suitable process.
- The roots andleaves are first cut 01f the stock of the plant, and the stock is then run through a succession of rollers, which-are immersed in water. Between these rollers it is pressed, to have the acid and liquid matter discharged from it. A mass of long fibres is thus produced. These long fibres are put through a set of toothed washing-rollers, whereby they are torn and still better cleaned.
The reduced fibre is then immersed in a bath of chloride of lime, mixed with hot water and taltam'c acid,
in about the proportions of one partof the chloride of lime to thirty-two parts of water, and to one thirt second-part of tartaric acid, and is thereby bleached.
In a second bathof oil of vitriol and water, mixed in about the proportions of one part of oil of vitriol to pulp is now generally treated or used.
I. do not claim the process herein described, nor any other process of producing paper-pulp from the plantain-tree; but
I do claim, and desire to secure by Letters Patent- Paper-pulp, prepared from the fibres of the plantainvtree, either in the manner herein set forth,.or otherwise,- as specified. p
The above specification of my invention signed by me, this 10th day of Ju1y,-1868.
\ C. (l. FITZGERALD. Witnesses:
ALEX. F. ROBERTS,
FRANK BLOCKLEY.
