PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Disintegrating, Opening, and
Removing Foreign Matters from the Roots of Jute and like
Fibrous Bodies.
1, CHARLES ROGER ORR, of Gourepore, Naihati, Bengal, India, Engineer,
temporarily residing at Hotel Windsor, Westminster, London, do hereby declare
the nature of this invention to be as follows:-
This invention has for object, the disintegration and removal of sand, earth, and
the like from the roots of jute and similar fibrous bodies by passing them over a
sieve like flooring by spiked rollers which are driven by any suitable power the
spikes being shaped like arrow heads to enter and open out the roots and their fibres
without tearing or destroying them.
The spikes of the rollers, say three in number are so arranged that they intercept
one another and are sufficiently distant apart as not to impede the passage of the
roots yet close enough to prevent roots escaping the operation.
The roots are fed to the machine at one end and are drawn gradually round upon
the sieve like flooring which may be of bars or battens having sufficient spacings
left for the debris to fall through and prevent clogging.
The roots then pass over the middle spiked roller to the under side of the next
spiked roller which is also over a sieve like flooring and passes out at an opening at
the back end of the frame.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Disintegrating, Opening, and
Removing Foreign Matters from the Roots of Jute and like
Fibrous Bodies.
I, CHARLES ROGER ORR, of Gourepore, Naihati, Bengal, India, Engineer,
temporarily residing at Hotel Windsor, Westminster, London, 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 has for object, the disintegration and removal of sand, earth, and
the like from the roots of jute and similar fibrous bodies by passing them over a
sieve like flooring by spiked rollers which are driven by any suitable power, the
spikes being shaped like arrow heads to enter and open out the roots and their fibres
without tearing or destroying them.
My invention will be thoroughly understood upon reference to the accompanying
two sheets of drawings in which
Figure 1 is a side elevation of the machine with the side frame removed.
Figure 2 is a part sectional plan showing the preferred method of driving the
disintegrating rollers.

page_text: Figure 3 is a side elevation of an alternative machine, the side frame being partly
broken away to more clearly show the construction.
Figure 4 is a part sectional plan, and Figure 5 is a section taken on the line a, b,
Figure 3. to more particularly show the arrangement of the roller and fixed
spikes.
Referring to Figures 1 and 2 it will be seen that arrow headed spikes A of the
rollers B, C, are so arranged that they intercept one another and are sufficiently
distant apart as not to impede the passage of the roots yet close enough to prevent
roots escaping the operation.
The roots are fed to the machine at one end through a hopper E by rollers a a
which receive it from an endless band 6 moving over the roller c and table d. The
table d which carries the endless band is hooked to the frame at e for convenience
of removal when desired.
The roots are drawn by the spiked roller B gradually round upon the sieve
like flooring formed of bars or battens F secured to the side frames G in any
convenient manner and having sufficient spacings H left for the debris to fall
through and prevent clogging. The roots then pass over the middle spiked roller C
to the under side of the next spiked roller D and pass out at an opening I at the
back end of the frames G.
The spiked rollers B, C, D, are enclosed by a covering J and are revolved in the
direction of the arrows preferably by belts K, L, to which motion is imparted from
any source of power and in any convenient manner.
In the modified arrangement shown in Figures 3, 4, and 5, the spikes A of the
rollers B, C, D, instead of alternately intercepting one another, are arranged in
increased numbers on each succeeding roller, the arrow headed spikes A. of each
roller being a slight distance apart from the spikes of the adjoining rollers.
Other arrow headed spikes M project from the floor of the machine and intercept
the spikes of the rollers in the manner more particularly shown at Figure 5, by
which means the fibrous roots are effectually opened out and the debris thoroughly
removed during the passage of the roots over the open flooring F, H.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved apparatus for opening out the roots and removing the foreign
matters from jute and like fibrous bodied roots, as described and shown in Figures
and 2 of the annexed drawings.
2. A machine for disintegrating and removing dirt, sand, and other foreign
matters from jute and like fibrous bodied roots consisting of arrow head spiked
revolving rollers and a sieve like flooring with or without fixed intercepting arrow
head spikes arranged and operated, as described and shown.
