An Improved Machine for Cleaning Fibrous Waste.
I JULIUS ALLMANN of the firm of Julius Allmann and Co. of Number 70 Deansgate
Manchester in the County of Lancaster, Engineer, do hereby declare the nature of
this invention, communicated to me by Henry Isitt of Boston, Massachusetts, United
States of America to be as follows:-
The said Invention relates to machinery employed in the separation of dust, dirt,
and other foreign matter from the waste produced in the manipulation and manu-
facture of fibrous materials such as wool cotton flax hemp jute and silk. In a machine
constructed in accordance with the said invention a hollow cylinder or drum is
provided with hollow gudgeons which are mounted to revolve in suitable bearings
carried by the framing of the machine. The shell of this cylinder is composed wholly
or partially of wire cloth netting perforated metal or of other similar reticulated or
perforated material or is covered with gratings the meshes or apertures being in each
case of such proportions as will be suitable to the material to be operated upon. A
part of the shell of the cylinder is hinged and is otherwise adapted to act as a door
through which the material can be introduced into and withdrawn from the cylinder
or if preferred there may be more than one door for the purpose or sliding or
removable doors may be provided instead of the hinged door. I prefer to provide
the opening closed by the said door in the periphery of the cylinder and to make such
opening to extend to the full length of the cylinder in order that the cylinder may be
readily charged and discharged. Suitable means are provided for fastening the door
or doors when closed. A shaft passes through the said hollow gudgeons and is also
mounted to be revolved in the same direction as the cylinder but at a higher velocity
as for example the shaft may make three revolutions for each revolution of the
cylinder. The relative velocities of the cylinder and inner shaft may be varied to.
suit the material to be operated upon and if found to be suitable in any case the said
cylinder and shaft might revolve in contrary directions. The said shaft carries arms
which project at different angles from the shaft and are of such a length as nearly to

page_text: touch the inner surface of the cylinder or some of the said arms may be relatively
shorter. A suitable quantity of the material to be cleaned having been introduced
into the cylinder and the door having been closed the cylinder and also the inner
shaft carrying the projecting arms are caused to rotate. Owing to the different
relative speeds of the shaft and the cylinder the material contained in the latter is
shaken and beaten by the arms projecting from the shaft and the dust which is
thereby separated falls through the apertures in the revolving cylinder on to the floor
or into a suitable receptacle under the cylinder or into a shute which conveys away
the said dust and any foreign matters passing through the meshes or apertures of the
cylinder shell. After the material has been operated upon for a suitable time it is
removed and the cylinder is charged with a fresh supply of uncleaned material.

COME LEIE SPECIFICATION.
An Improved Machine for Cleaning Fibrous Waste.
I JULIUS ALLMANN of the firm of Julius Allmann and Co. of Number 70 Deansgate,
Manchester in the County of Lancaster, Engineer, do hereby declare the nature of
this Invention (communicated to me by Henry Isitt of Boston, Massachusetts, United
States of America) and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement and accompanying
drawings :-
The said Invention relates to machinery employed in the separation of dust, dirt,
and other foreign matters from the waste produced in the manipulation and manu-
facture of fibrous materials such as wool cotton flax hemp jute and silk. In a machine
constructed in accordance with the said invention a hollow cylinder or drum pervious
to dust and dirt is mounted to revolve in suitable bearings carried by the framing of
the machine. A shaft passing through the said cylinder or drum is also adapted to
be revolved in the same direction but at a higher velocity. The said shaft carries
arms which project from the shaft and act upon charges of waste introduced into the
cylinder or drum.
The invention will be best understood when described with reference to the
accompanying drawings in which Fig. 1 represents a Vertical Longitudinal Section
of the machine and Fig. 2 a Vertical Cross Section of the revolvable cylinder of the
same. In the said Figs. A is the said cylinder or drum b is the revolving shaft
and c c are the said arms. The said cylinder consists principally of two ends or discs a
which are united by longitudinal bars a¹ so as to form a cage. The spaces between
the said bars are closed by means of curved sheets of wire cloth or netting perforated
inetal or other similar perforated or reticulated material or of gratings the meshes or

page_text: apertures being of such proportions as will be suitable to the material to be operated
upon. A part of the circumference of the cylinder is hinged and is otherwise adapted
to act as a door through which the material can be introduced into and withdrawn
from the cylinder or if preferred there may be more than one door for the purpose or
sliding or removable doors may be provided instead of the hinged door. The space
between two of the bars a¹ is closed by means of a hinged door d consisting of a
frame covered with the pervious material. When the said door is turned back
an opening is uncovered which extends to the full length of the cylinder so that the
latter can be readily charged with the waste. When the door is shut it forms a part
of the circumference of the cylinder. Suitable latches or fastenings are provided for
securing the door when it is closed. Each of the two ends a is formed with a hollow
gudgeon which is turned to suit a bearing formed in one or the other of the two
standards e. e wherein the cylinder is mounted so that it can be revolved upon an
axis which is or may be horizontal or thereabouts. The two standards are connected
together so as to form a framing for the machine. The shaft & passes through the
hollow gudgeons and is fitted to revolve in bearings formed in such gudgeons or in
other suitable bearings formed in or secured to the standards e as preferred. The
arms c. c in the example are supposed to be inserted in slots or openings formed in
the shaft so that each arm projects in opposite directions from the shaft but the
arms may be otherwise secured to the shaft in any suitable manner and may be made
of metal or of wood or other suitable material. In the example the arms or some of
them are inclined from what would be a right angle with the axis of the shaft but
this inclination may be varied or the arms may be fixed at right angles as indicated
by the dotted lines at c¹ as considered to be most suitable. By preference the ends of
the arms extend nearly to the bars a' so that the arms clear the inner circumference
of the cylinder but the arms might vary in length if considered to be desirable. The
shaft b is provided with a belt pulley whereby the shaft can be revolved at a com-
paratively quick speed. Upon the said shaft is fixed a second pulley 9 which gives
motion by means of a belt to a counter shaft h which is mounted in bearings in the
upper ends of the standards. Upon the said shaft are fixed pulleys ii which are
connected by means of belts with larger pulleys k. k which are secured to the end
plates a or to the gudgeons on the said plates. The arrangement is such as that the
cylinder or cylindrical cage revolves in the same direction as the shaft but at a slower
speed. The method of imparting or conveying motion to the cylinder may be varied
so long at the relation between the motions of the cylinder and the inner shaft are
maintained. The machine is used in manner as follows. A charge of the material to
be cleaned is introduced through the opening at d the door d is closed and secured
and the shaft and cylinder are set in motion. Owing to the different relative speeds
of the shaft and the cylinder the material contained in the latter is shaken and beaten
by the arms e and the dust which is thereby separated falls through the apertures in
the circumferential part of the revolving cylinder on to the floor or into a suitable
receptacle under the cylinder or into a shute which conveys away the said dust
and any foreign matters passing through the meshes or apertures of the cylinder
shell. After the material has been operated upon for a suitable time it is removed
and the cylinder is charged with a fresh supply of uncleaned material. The discharge
of the contents of the cylinder may be facilitated by stopping the cylinder in such a
position as that the contents can be readily raked out or withdrawn from the interior
of the cylinder. If preferred for any reason an opening or two or more openings
closed by a door or by doors might be formed in one or in each of the ends a. If
preferred the ends a might be perforated or slotted or formed with openings closed by
means of gratings or of slotted perforated or reticulated plates or sheets. Although
for convenience of description I have referred to the part A under the designation of a
cylinder it must be understood that although the cylindrical form is considered to be
the most effective the term cylinder is not intended to exclude polygonal or other
forms which might for any reason be considered to be suitable and although I prefer
to revolve the cylinder or cage and the central shaft in the same direction as described
I do not confine myself to the one direction of revolution.

page_text: Having now particularly described and ascertained the nature of the said: Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
(1) The combination of parts forming the complete apparatus substantially as and
for the purpose set forth and indicated herein before and in and by the accompanying
drawings.
(2) In apparatus for cleaning fibrous waste a cylinder or cage having its circum-
ference made pervious by the indicated means mounted to revolve in combination
with a central or inner shaft provided with projecting arms and also adapted to
revolve on the same axis as the cylinder substantially as set forth and indicated.
(3) A machine for cleaning fibrous waste having a revolvable cylinder drum or
cage made pervious to dust and dirt and formed with an opening which is provided
with a door and a shaft revolving on the same axis as the cylinder in the same
direction but at a quicker speed the said shaft being provided with projecting arms
which act upon the waste substantially as set forth and indicated.
