PROVISIONAL SPECIFICATION.
Improved Apparatus for Opening and Separating Jute and like Roots
for the purpose of Preparing Fibres therefrom for Manufacturing
purposes.
I, CHARLES ROGER ORR, of Gourepore, Naihati, Bengal, India, temporarily
residing at The Grand Hotel, Northumberland Avenue, Charing Cross, County
of London, Engineer, do hereby declare the nature of this invention to be as
follows:
This invention has for object; .the construction of machinery or apparatus by
which after a crushing operation, the roots of jute or like plants are fed to a
spiked roller and torn by contact with fixed spikes on a segmental. adjustable
plate from which after passing or being carried over an open plate or grating
they are further acted upon in succession by a series of spiked rollers and spiked
segmental plates, the casing of each series having an open plate or grating for
the dust and refuse to escape, so that fibre only will leave the opposite end of
the machine.
For the purpose of my invention, I connect up a series of casings, say, four
or more, or as desired. Each casing is provided with ledges or supports, for
gratings or sifting bars, and also for segmental plates which have spikes attached
or as part of these being arranged concentrically to spike faced plates constituting
rollers, the axles of which are carried in bearings of the casings and driven at
the required speed or speeds.
The roots to be operated upon are fed by an endless travelling band to between
a pair of plain or chequered crushing rollers from which they drop and become
fed by a hopper to between the spikes of a moving roller which drag them into
contact with spikes of a fixed breast plate and effects the first separation, the
roots being then carried round by the roller spikes over an openworked screen
or grating for the escape of dirt and small refuse to a drawer or box placed
under it. The roughly separated portions of the roots are gathered and heaped
up by the spiked roller and caused to come within range of a second spiked
roller which in its turn drags the roots downwardly and in contact with spikes
of a half breast plate where they are further opened out and separated and are
carried round and over a grating or sieve for removal of fresh formed debris
into a third and, say, a fourth similarly arranged casing with spiked roller,
spiked half breast plate, and grating sieve before delivery from the machine.
The spikes of the second and after rollers may be arranged to correspond with
those in the first roller, and the same may be the case with those of the half
breast plates or the arrangement of the spikes of the rollers and half breast
plates may gradually diminish towards the delivery end of the machine, so that
little else than actual fibre or staple fit for spinning or other after treatment is
the result.

I, CHARLES ROGER ORR, of Gourepore, Naihati, Bengal, India, temporarily
residing at The Grand Hotel, Northumberland Avenue, Charing Cross, County
of London, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention has for object, the construction of machinery or apparatus by
which after a crushing operation, the roots of jute or like plants are fed to a
spiked roller and torn by contact with fixed spikes on a segmental adjustable
plate from which after passing or being carried over an open plate or grating
they are further acted upon in succession by a series of spiked rollers and spiked
segmental plates, the casing of each series having an open plate or grating for
the dust and refuse to escape, so that fibre only will leave the opposite end of
the machine.
My invention will be understood from the following description aided by the
accompanying drawings in which Figure 1 is a plan of the apparatus with the
drawing in section. Figure 2 is a side sectional elevation of the machine.
For the purpose of my invention, I connect up a series of casings A, A',
A, A, say, four or more, or as desired. Each casing is provided with ledges
or supports B, B1, B", B, for gratings or sifting bars C, U, C, C, and also
for segmental plates D, D₁, D", D, which have spikes E, E¹, E, E, attached
or as part of, these being arranged concentrically to spike faced plates F con-
stituting rollers, the axles G of which are carried in bearings of the casings A,
A', A", A and driven at the required speed or speeds through the pulleys H,
H', Hu, H
The roots to be operated upon are fed by an endless travelling band I to
between plain or chequered crushing rollers J from which they drop and become
fed by a hopper K to between the spikes 11 of the first moving roller which
drag them into contact with spikes E of the fixed breast plate D and effects the
first separation, the roots being then carried round by the roller spikes F¹ over
an openworked screen or grating C for the escape of dirt and small refuse to a
drawer or opening under it. The roughly separated portions of the roots are
gathered and heaped up by the spiked roller and caused to come within range
of a second spiked roller which in its turn drags the roots downwardly and in
contact with spikes E of a half breast plate 1 when they are further opened
out and separated and are carried round and over a grating or sieve C¹ for
removal of fresh formed debris into a third and, say, a fourth similarly arranged
casing with spiked roller, spiked half breast plate, and grating sieve before
delivery from the machine."
The spikes of the second and after rollers may be arranged to correspond
with those in the first roller, and the same may be the case with those of the
half breast plates or the arrangement of the spikes of the rollers and half breast
plates may gradually diminish towards the delivery end L of the machine, so
that little else than actual fibre or staple fit for spinning or other after treat-
ment is the result.
The spike faced plates F are secured to discs or end plates M fixed on the
axles G by their lugs N so as to constitute the roller, and the spiked breast

page_text: pieces D, D, D", D, are secured to the ledges B of the frame A and may be
adjustable thereon by any suitable means to suit the material under operation.
P, is a shield to the endless travelling apron 1 to prevent the roots leaving
the apron during the travel to the crushing rollers.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
-
1. The improved apparatus for opening and separating jute and like roots for
the purpose of preparing fibres therefrom for manufacturing purposes, consist-
ing of a casing, provided with a spiked roller, a spiked breast plate, and a
grating arranged and operating as set forth.
2. Constructing a spiked roller from a number of spiked plates F secured to
end plates M, in combination with an adjustable spiked breast piece D and
grating C, all arranged within a casing A, substantially as set forth.
3. The combination of a number of casings A secured together and provided
with spiked rollers formed from spiked plates, a breast plate or piece having
spikes, and a grating, all arranged substantially as set forth for the purpose
described.
