We, PETER SWIRES HORSMAN, of St. John's Beckermet, in the County
of Cumberland, Gentleman, and WILLIAM GOODALL, of Halifax, in the
County of York, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR SPINNING, DOUBLING, AND TWISTING FIBROUS
SUBSTANCES," to be as follows :—
-
The object of our Invention of improvements in machinery for
spinning, doubling, and twisting, fibrous substances, is to construct the
spinning mechanism in such a manner that it may be materially
lightened or reduced in weight, and that the vibration of the spindles
and flyers when driven at a high speed may be prevented.
In combination with the novel construction of the spinning mechanism,
an improved drag is provided, so that by means of our various improve-
ments the mechanism may be driven at a greatly increased speed
without injurious vibration, and an uniform drag on the bobbin obtained
for the winding up of the yarn or threads

The improved spinning mechanism consists of a fixed spindle, on the
pointed top of which is mounted a tube closed at one end. This tube
freely revolves on or around the fixed spindle and extends downwards
through the traverse or bobbin rail and through the bush in the spindle
rail. At the lower end of this tube is fixed a pulley or wharve round 5
which passes a band or tape from the driving cylinder, by which the
spinning mechanism is actuated in the usual way. A small hole is made
in the closed end of the tube to receive a small quantity of oil for
lubricating the pointed end of the fixed spindle. The flyer is attached
to the upper or closed end of the tube by means of a screw and is 1
actuated in the usual manner. The lower end of the fixed spindle
passes down through the spindle step rail or bottom rail, and rests on a
plate attached to the under side of this bottom rail by means of
adjusting screws, so that all the spindles in the frame can be adjusted to
an uniform height.
1
In some cases when it is not desirable that the fixed spindle should be
kept in the vertical position by the interior of the tube, an additional
spindle rail may be placed a little lower than the wharve or pulley
through which the fixed spindle is inserted. By this means the fixed
spindle is kept steady in its position, the tube being allowed to revolve 2
on the pointed top of the fixed spindle without vibration.
In order to produce the proper drag on the bobbin so as to wind up
the yarn or thread thereon in an uniform manner, a plate is attached
to the bobbin or traverse rail immediately in front of each spindle.
Projecting brackets from the bobbin rail support the fulcrum of a lever, 2
one end of which is inserted into a groove cut in the periphery of the
bobbin; the other end of the lever extends under the traverse or bobbin
rail towards the spindle, and this end may be weighted so as to cause
the upper end of the lever to press upon the bobbin and force it down
against the top or surface of the traverse rail. The friction thereby 8
produced gives the required drag or retardation to the rotation of the
bobbin, so that the yarn or thread is lapped or wound thereon in a
regular manner.
In order that the drag or retardation may be more easily regulated, a
second lever supported from the bobbin rail is made to bear on the 8
lower or tail end of the first lover, the end of which is bent into a
horizontal direction so as to support the second lever. A moveable

page_text: weight is placed on the second lever instead of on the horizontal arm of
the first; this weight may be moved to any position along the second
lever so as to regulate the pressure on the first lever, and consequently
the force with which the bobbin is pressed down on the traverse rail.
The amount of drag or retardation to be given to the bobbin may
therefore be regulated and adjusted with the greatest facility and
accuracy, by merely moving the weight along its lever.
