page_text: LETTERS PATENT to Herbert John Haddan, of Kensington, Middlesex, for an
Invention of "IMPROVEMENTS IN PROCESS AND APPARATUS FOR DISINTE-
GRATING JUTE AND FIBROUS STALKS." A communication from abroad by
Albert Angell and William Brough Cunningham, both of New York City,
United States.
COMPLETE SPECIFICATION filed by the said Herbert John Haddan at the
Office of the Commissioners of Patents on the 31st January 1882.
HERBERT JOHN HADDAN, of Kensington, Middlesex. "IMPROVEMENTS IN PROCESS
AND APPARATUS FOR DISINTEGRATING JUTE AND FIBROUS STALKS." A com-
munication from abroad by Albert Angell and William Brough Cunningham, both
of New York City, United States.
This Invention relates to an improved process for disintegrating jute and other
fibrous stalks, and consists in splitting the same, and then removing therefrom the
pith and the shell, skin, or bark, as hereinafter described.
In carrying out this process a inachine is used consisting of elastic feed rollers,
knife for splitting the stalks, and interlocking scrapers for simultaneously removing
the pith and the shell, skin, or bark from the split stalks.
In the accompanying Drawing, Figure 1 is an end view of the inachine; Figure 2
is a longitudinal central section. Similar letters indicate corresponding parts.
In these Drawings the letter A designates the frame of the machine; and B, a table
on which the jute, stalk, or other material to be disintegrated may be placed so as
to have the same ready at hand for passing into the machine. When sliding down
the incline C the jute or stalks are caused to pass between the feed rollers D, D,
connected by suitable gears and revolving in opposite directions. These feed rollers
are made of india rubber or other elastic material, so that they do not crush the
stalks, but they serve to force the same forward against the knife F where they are
split, each into two parts or halves. In passing from this knife the two halves are
exposed to the action of interlocking scrapers, caused to revolve in opposite
directions by means of gears. These scrapers act on both sides of the material, and
separate from the same simultaneously the pith, and also the skin, shell, or bark.

page_text: Suitable driving pulleys or other fit means are employed to give motion to the feed
rollers D and scrapers E, which are caused to take the proper motions with
relation to one another by means of gears, as shown in the Drawing.
When the pith and outer bark have been removed from the stalks in the manner
above described, then the fibre is boiled in an alkaline bath and passed through 5
water by means of a gang of rollers, which feed the same forward, squeeze it, and
pass it through the water so as to remove the gum.
CLAIMS.
1. The berein described process of disintegrating jute and other fibrous stalks
by first splitting the same, and then exposing the split stalks to the action of 1
interlocking scrapers for removing therefrom simultaneously the pith, and the skin,
shell, or bark, substantially as set forth.
2. The combination, substantially as herein before described, of the elastic feed
rollers, the splitting knife, and the interlocking scrapers.
3. The within described process for treating jute and other fibrous stalks by first 1
removing therefrom the pith and the outer bark, then boiling the fibre in an
alkaline bath, and finally exposing the same to tho action of squeezing rollers
under water for the purpose of removing the gum.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal, this Thirty first day of January, A.D. 1882.
