Spinning and Drawing Machines.
I WILLIAM ALBERT DELMAGE of 11 Bridge Street Lowell in the County of
Middlesex, and State of Massachusetts, United States of America Overseer of
Spinning do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide for spinning and drawing machines, a
scavenging device for collecting the broken ends of the yarn and the waste produced
by the usual drawing rolls, and conducting them away so that they do not become
entangled with the other threads.
My invention consists in a pair of auxiliary rollers arranged to receive the broken
ends of the thread from the drawing rolls, and in a pneumatic tube arranged to receive
the waste from the auxiliary rollers and conduct away.
The invention also consists in the employment of a roller formed of hard rubber or
other material capable of generating electricity by friction, the object being, to create
an electrical attraction which will draw the broken threads and waste to the said roller,
whence they are transferred to the pneumatic tube as before or carried away by
mechanical means as hereafter described.
According to one arrangement the pair of auxiliary rollers are arranged with their
bite immediately beneath the front pair of drawing rolls and they are partly enveloped
by concaves formed on the edges of a longitudinally slotted pneumatic tube.
This slot is situated between the concaves and immediately below the line of bite of
the auxiliary rollers; and it allows the broken threads and wasto received between the
rollers to pass into the tube.
The frame which supports the tube and the auxiliary rollers is provided with a
hinged arm secured by a catch, which holds the pneumatic tube in place and permits
of its removal when it is desired to clean it.
Motion is imparted to the rollers by gear from the drawing rolls and the broken
ends of thread and waste which are delivered by the front drawing rolls are received
by the auxiliary rollers and transferred to the tube. The tube extends to a con-

page_text: venient place for discharge, and a current of air carries the waste into a chamber
closed by wire cloth which permits the air to escape, but retains the waste.
One means of collecting and removing the waste consists of a rotating cylindrical
screen which is so arranged in relation to the tube and to a suction fan that the
waste will be projected by the air current upon the reticulated surface of the
screen and will remain adherent thereto whilst the air passes through to the fan.
At the under side of the trunk or case of the screen is a removable box to
receive the waste, a toothed stripping roller being mounted to rotate in contact
with the underside of the screen to remove the. adherent waste and deposit it in
the box.
Hung within the screen is a stationary segmental plate or shield to obstruct the
meshes of the screen at the lower part and prevent the waste adhering too firmly
at the point where it is removed by the stripping roller.
If the auxiliary rollers are placed one above the other so that their bite is not
opposite the point of delivery of the front drawing rolls,
The upper roll is made of or covered with hard rubber or other material capable
of electrification. The auxiliary rollers receive motion as before, and a pneumatic
tube having an opening opposite the bite of the auxiliary rollers is provided with
packing strips along its edges contacting with said rollers to prevent leakage of
air and to excite the upper roller electrically, so that it will attract the broken
threads and waste delivered by the drawing rolls, and will retain it while it is
carried round and delivered to the pneumatic tube, the waste being removed from
the surface of the rollers by the edges of the tube and by the packing.
Instead of using a pair of auxiliary rollers for receiving the waste from the drawing
rolls a single electrically charged roller may be used, a rubbing strip being held in
contact with the said roller for exciting the roller and removing the waste therefrom
and depositing it in a box beneath, wherein runs an endless belt which carries a wiper
for removing the waste from the box. This arrangement of the electrical roll and the
wiper allows me to use one roll instead of two for receiving the waste and to employ
a belt and wiper instead of a pneumatic tube for carrying the waste away.

I WILLIAM ALBERT DELMAGE of 11 Bridge Street Lowell in the County of
Middlesex and State of Massachusetts, United States of America, Overseer of Spinning
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:
The object of my invention is to provide, for spinning and drawing machines, a
device for collecting the broken ends of the yarn and the waste produced by the usual
drawing rolls and conducting them away, so that they do not become entangled with
the other threads.
My Invention consists, first, in a pair of auxiliary rollers placed below the drawing
rolls, and arranged to receive the broken ends of the thread from the drawing rolls,
and in a pneumatic tube arranged to receive the waste from the auxiliary rollers and
conduct it away.
The Invention consists, secondly, in the employment of a roller formed of hard
rubber or other material capable of generating electricity by friction, the object being
to create an electrical attraction which will draw the broken threads and waste to the
said roller, whence they are transferred to the pneumatic tube or carried away by
inechanical means.
Reference is to be had to the accompanying drawings forming part of this Specifi-
cation in which figure 1 is a vertical transverse section of a part of a machine to which
my improvement has been applied; Figure 2 is a detail view of the pneumatic tube
connected therewith. Figure 3 shews a modified arrangement; Figure 4 is a detail
sectional view of the pneumatic tube used in connection therewith. Figure 5 is a side
elevation, with parts broken away and others in section, of contrivances embodying
my invention. Figures 6 and 7 are detail views shewing the screen and adjunctive
part thereof, respectively, and figure 8 is a vertical transverse section shewing a
modified form of the electrical attachment.
The drawing rolls A of the spinning machine are constructed and arranged in the
usual way.
In figure 1, below the front or lower pair of rolls A are journaled a pair of rolls B
whose under surfaces are partly enveloped by the concaves C formed on the edges of
the longitudinally slotted tube D. The slot a of the tube is situated between the
concaves C and immediately below the line of contact of the two rollers B, and it
allows the broken threads and waste received between the rollers B to pass into the
tube D, said slot being arranged in alignment with a plane passing intermedially of the
auxiliary rollers. The frame F which supports the tube D and the rollers B, is provided
with a hinged arm E secured by a catch a¹ which holds the pneumatic tube D in place
and which is unfastened and dropped down when it is desired to remove the pneumatic

page_text: tube, for the purpose of cleaning it. Motion is imparted to the rollers B (as herein-
after described) and the broken ends of thread and waste which are delivered by the
lower rolls A are received by the rollers B and transferred to the tube D. The tube D
extends to a convenient place for discharge, and a current of air driven or drawn
through it, carries the waste discharged into the tube into a chamber closed upon its
side by wire cloth which permits of the escape of the air, but retains the waste.
One means of collecting and removing the waste from the pneumatic tube D consists
of a rotating cylindrical screen I (figure 5) which is arranged transversely to the tube
and between it and the suction fan J, said screen being enclosed in a trunk or casing
connecting with the tube at one side and with the suction inlet of the fan on the other,
as shewn so that the waste will be projected upon the reticulated surface of the
screen and will remain adherent thereto whilst the air passes through to the fan.
The screen I is rotated from one of the shafts of the rolls B through bevel gear e e¹,
the roll shaft being driven through pinions; from the shaft of one of the rolls A.
The roller shafts B are geared together by equal pinions k.
The fan can be driven by a belt from the screen shaft.
Below an opening at the underside of the trunk or case of the screen I, is disposed
a receptacle H for the waste which is stripped from the revolving screen and delivered
into the receptacle H by a toothed stripping roller i mounted beneath the screen within
the receptacle. Within the cylindrical screen, a stationary plate or shield G is hung
loosely from the screen shaft, the object of the shield (which is curved to a segment
of a cylinder) being to prevent the current of air from entering the lower side of the
screen where the clearing cylinder i takes the waste therefrom, and causing the waste
to adhere to the screen so as to prevent in a measure the removal of the waste by the
action of said cylinder.
In the modification shown in figure 3, below the lower pair of rolls A³ are journaled
two rolls G H one above the other, the upper roll G being made of or covered with
hard rubber or other material capable of electrification. The rolls G H receive motion
in same manner as the rollers B B, and a pneumatic tube D' having a longitudinal
opening opposite the bite of the rollers G H, is provided with packing strips 6' along
its edges contacting with the said rolls G H to prevent leakage of air between the tube
and rollers. The packing which bears upon the surface of the roller G serves to
excite it electrically so that it will attract the broken threads and waste delivered by
the lower pair of rollers A' and will retain it while it is carried round and until it is
delivered by both rolls G H into the tube D', the waste being removed from the surface
of the rollers by the edges of the tube D' and by the packing b. The standard I by
which the rollers G H and the tube D' are supported is provided with an armı c which
partly encircles the tube D' and is provided with a hinged part c¹ which may be
opened when it is desired to remove the tube D¹ for the purpose of cleaning it when
it becomes clogged.
In figure 4, I have shewn a tube D' which is opened upon one side and is provided
with V-shaped channels d for receiving the packing bl.
In figure 8, I have represented a single electrically charged roll A² placed under
the drawing rolls A. At the underside of the roll A2 is a rubbing strip a² for exciting
the roller and removing the waste, said strip being held in contact with the roller A
by a steel strip B secured to the stand which supports the roll; The hox C² supported
by the frame below the roll A2, contains an endless helt D2 which carries a wiper for
removing the waste from the box (2. This arrangement of the electrical roll and the
wiper, allows me to use one roll instead of two, for receiving the waste and to employ
a belt and wiper instead of a pneumatic tube for carrying the waste away.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed I declare that what I claim is ;
1. The combination with the drawing rolls, of the auxiliary rolls and the slotted
pneumatic tube, and means to produce a current of air through the tubes and to rotate
the auxiliary roll from the drawing roll, said auxiliary rolls being disposed contiguously

page_text: to the drawing rolls and the tube having its slot arranged in alignment with a plane
passing intermedially of the auxiliary rolls, substantially as shewn and described, and
for the purpose set forth.
2. The combination with a pneumatic tube having a slot in one side thereof of a
roll formed wholly or in part of hard rubber or other material capable of electrification
and a packing adapted to electrically excite said roller and for creating a current of
air through said tube, substantially as and for the purpose set forth.
3. In scavenger mechanism for spinning and drawing machines, the combination
with the rolls for receiving the waste from the drawing rolls and the pneumatic tube
for conveying away the waste, of a frame for supporting the pneumatic tube provided
with a binge to admit of removing the tube, as herein specified.
4. The combination with a slotted pneumatic tube D¹ and rolls G H of packing
strips 6 attached to the edges of the pneumatic tube, and bearing against the rolls,
together with means for creating a current of air through the pneumatic tube and for
the rotating the rolls, as herein specified.
5. The combination with the roller A² capable of electrification, of the tube C³ and
the belt D2 carrying wipers for removing the waste, substantially as described.
6. The combination with the drawing rolls A of the roller A² capable of electrifica-
tion the packing strip a² held in contact with the roller A², the tube C2 arranged below
the roller and carrying the endless belt D² provided with wipers, substantially as
described.
