COMPLETE SPECIFICATION filed by the said Alexander Melville Clark at the
Office of the Commissioners of Patents on the 23rd March 1876.
ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex,
Patent Agent. "IMPROVEMENTS IN MACHINERY FOR SPINNING WOOL, COTTON, AND
OTHER FIBROUS SUBSTANCES." A communication from abroad by James Hunter
and James Edwin Hunter, both of Adams, in the County of Berkshire, and State of
Massachusetts, United States of America.
This Invention consists in the mode of delivering and drawing the roving and
winding the spun yarn on to the continuously revolving spindle directly from the
delivery rollers. It is accomplished by having the delivery rollers placed on rocking
bars together with the drum which supplies the roving to the delivering rollers.
These rocking bars are moved by an eccentric or crank, or other device away from
the spindle and back, causing an oscillating motion alternately to and from the
spindles, the roving being drawn as the bars move from the spindles, and the
being wound on the continually revolving spindles as the bar moves toward them.
As the rocking bar begins to recede from the spindle a certain amount of roving
is delivered and drawn, thus continually delivering, drawing, and winding on to
the spindle or the bobbin on the spindle."
уain
In order to allow the yarn to be wound on to the spindle a lifting bar is used to
raise the thread off from the points of the spindles, as the rollers are moved
toward the spindles and the bar is again depressed at the proper time to allow the
threads to wind around the point of the spindle preparatory to the roving being
delivered and drawn, as before stated.
This Invention is not confined to the employment of a rocking bar, for the same
result may be accomplished by moving the rollers and roving to and from the

page_text: spindles on a carriage, or the carriage may carry the spindles to and from the
rollers. In the accompanying Drawings the rocking bar is shown as being most
simple and easily described.
In the accompanying Drawings,—
Figure 1 represents a perspective view of a spinning frame.
Figure 2 represents a vertical section of a spinning frame.
Figure 3 represents the lifting bar raised and the yarn winding on to the bobbin.
Figure 4 represents the lifting bar lowered and the yarn being drawn and
receiving the twist.
Figure 5 represents a top view of lifting bar and spindle.
Figures 6, 7, 8, and 9 represent the variable cam for giving the proper motion
to the rocking bars.
Similar letters of reference indicate corresponding parts.
On the frame A on top of the rocking bars S, S, is mounted a drum B which
holds the roving, also the delivering rollers C, D, E, which are held in their
bearings.
A rotary motion is imparted from the cylinder H to the rollers C and D and the
drum B by gearing or other suitable mechanism, and the roller E lies on the top
and between the rollers C and D. The roving passes from the drum B in the usual
way under the rollers E and over the rollers C, D, to the spindle F which has a
continuously revolving motion in one direction, and the rollers are moved to and
from the spindles, alternately delivering and drawing, and in connection with the
lifting bar G wind the yarn on to the spindle or the bobbin on the spindle in the
usual way by the ring and traveller or flier, or their equivalent, the whole as
described and shown by the Drawings.
Having described the nature of the Invention and the manner of performing the
same, I declare that what I claim as new and desire to secure by Letters Patent
is,-
1st. The combination of the movable yarn delivering rollers and the continuously
revolving spindle, substantially as described.
2ud. The lifting bar in combination with the continuously revolving spindle for
the purpose of lifting the yarn off from the point of the spindle and holding it up
while it is receiving the twist and being wound on to the spindle without reducing
the speed thereof.
3rd. The graduating cams so arranged that the draft can be regulated by moving
the central arm towards the warp or woof cam, thus spinning warp or woof as
desired.
In witness whereof, I, the said Alexander Melville Clark, have hereunto set
my hand and seal, this Twenty-second day of March, in the year of our Lord
One thousand eight hundred and seventy-six.
