PROVISIONAL SPECIFICATION.
Improvement in the Treatment of Fibrous Plants for the Purpose
of Obtaining Fibres therefrom.
I, DONALD STUART of 58, Chancery Lane, London in the County of Middlesex
Engineer do hereby declare the nature of this invention to be as follows :-
This invention applies to the extraction of fibre from aloe, jute, pine apple,
ramic, manila, sansiveria, flax, & kindred plants in their green state, in perfecting
the material for the scutcher after being crushed, by the injection of steam & water
thro' the mass, by which means the pulp is speedily released, & the gums &
other adhesive matter, being held in solution, absolutely removed, the application
of wet or superheated steam (as may be required), so regulating the temperature
during the process of scutching, as to prevent any reaction, & thereby producing
a perfectly cleaned fibre, free of all gums & foreign matter.

COMPLETE SPECIFICATION.
Improvement in the Treatment of Fibrous Plants for the Purpose
of Obtaining Fibres therefrom.
I, DONALD STUART 58 Chancery Lane London W.C. Engineer do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention applies to the extraction of fibre from aloe, jute, pine apple,
ramie, manila, flax, sansiveria, & kindred plants in their green state in perfecting
the material for the scutcher after being crushed, by the injection of steam &
water thro' the mass, by which means the pulp is speedily released, & the gums
& other adhesive matter being held in solution absolutely removed, the application
of wet or superheated steam (as may be desired) so regulating the temperature
during the process of scutching as to prevent any reaction, & thereby producing a
perfectly cleaned fibre freed from all gums or foreign matter.
The drawing hereto annexed will describe the nature and application of my
invention as follows:-
A, is a steam pipe.
B, is a water pipe.
C, C, are perforated nozzles for injecting combined steam and water into the
compressed fibre.
D, is a perforated steam nozzle for injecting steam into the fibre during
scutching.
E, is an ordinary feed table for delivering the fibre to the rollers F, F.
F, F, are ordinary crushing rollers.
G, is a table for delivering the crushed fibre to scutcher H.
H, is an ordinary scutching wheel.
K, K, are bands for holding down crushed fibre.
The crushed fibre is delivered to the table G from the rollers F, F, where it is
submitted to the combined action of steam and water from the pipes A, B, through
nozzles or perforations C, C. The fibre passes thence to the scutcher H, when

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is :-
:―
1st. That the application of steam & water combined after the plant is crushed,
perfects the material for the scutcher, the woody portions being pulped & thereby
preventing waste during the process.
2nd. At a fixed temperature, the gums, etc., in the plant when expanded by
steam & water (pure or chemically prepared) is completely released.
3rd. By regulating the temperature before & during the process of scutching,
a re-action is obviated.
