for an Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF MACHINERY
OR APPARATUS EMPLOYED IN THE PREPARATION OF COTTON AND OTHER

THE
"IMPROVEMENTS
ROGER SOUTHWORTH, of Bolton, in the County of Lancaster.
THE CONSTRUCTION OF MACHINERY OR APPARATUS EMPLOYED IN
PREPARATION OF COTTON AND OTHER FIBROUS MATERIALS FOR SPINNING."
IN
This Invention relates to the construction of what are known as "roving,"
"slubbing," "intermediate," and "jack frames," and the principal objects of the
Invention are to simplify the construction, to reduce the vibration, to facilitate
doffing and piecing, and to enable the frames to be run at a higher velocity, and to
produce a more even yarn than heretofore.
The principal features of the Invention relate to the construction and
arrangement of the flyers and spindles and their connections.
In the first place the flyer (instead of being fixed onto the top of the spindle as
usual) is separate from the latter, and the two are driven separately and
independently of one another.
The flyer is made much longer than usual and is closed at both ends, having a
bow and a short tube or neck at the top and bottom, the upper neck being merely
drilled through vertically and not having any hole or eye at the side. These tubes
or necks run in short collars attached to fixed rails at top and bottom, and on
the lower tube is fixed the wheel which drives the flyer.
The spindle is much shorter than usual in order that when the spindle rail is at
its lowest position, there shall be a sufficient distance between the top of the spindle

page_text: and the top of the flyer to allow of the doffing of the bobbin. By this arrangement
the doffing and piecing are rendered much simpler; the flyers are never removed
from the frame, and being closed at both top and bottom, and having also collars
or bearings both above and below, they will run much more steadily at a high
velocity without the arms expanding and with much less vibration than
heretofore.
The spindles are provided with fixed collars to support the bobbins and are
carried in the spindle rail, to which is given the rising and falling motion necessary
for the regular winding on of the yarn.
The spindles fit in and revolve through the lower tubes of the flyers which thus
act as a bearing, and the long collars usually employed are dispensed with.
The bobbins being carried and driven by the spindles direct, the relative speeds
of the spindle and flyer must be so regulated as to cause the winding on of the
yarn to be effected in an even and regular manner as the twisting of the sliver or
yarn proceeds. The lifting rail only carries the spindles which are driven by bevel
gear attached to a fixed rail, the spindles being squared, or otherwise so arranged,
that they can rise and fall through the bosses of their respective wheels at the
same time that they are driven by them.
The lifting rail being thus much lighter, the ordinary chains and counter balance
weights are dispensed with and small weighted levers are employed instead, and
as the driving gear is attached to a fixed rail and does not rise and fall with the
bobbins and spindles the "swing motion" usually employed will not be requisite.
