APPARATUS FOR SPINNING FLAX, HEMP, JUT'E, AND OTHER FIBERS.

Specification of Letters Patent.

Patented Nov. 25, 1913.

Application filed March 14, 1913. Serial No. 754,341.

To all whom it may concern:

Be it known that I, GEORGE SHAW, a British subject, residing at Leeds, county of York, England, have invented certain new and useful Improvements in Apparatus for Spinning Flax, Hemp, Jute, and other Fibers, of which the following is a specification.

This invention relates to apparatus for spinning yarn from flax, hemp, jute and other similar fibers. Spinning frames of this class are made with a revolving spin face of the cop or bobbin on the spindle C.

ning rlng driven by a band and provided with a guide eye to direct the yarn to the spindle, or with a disk carrying a flierleg and presser to lay the yarn on the spindle.

The invention consists essentially in the application to a revolving ring of a diameter through which the cop or bobbin can pass, of a centrifugal or spring presser pivoted at one side of the ring and provided with a guide eye for the yarn affixed eccentrically to the upper end of the presser flier leg, the drag or pressure of the yarn upon which assists the centrifugal mot-ion to force the presser against the cop or bobbin, and also of a spring actuated or controlled brake to bear against the rim of the revolving ring to retard or stop its rotation, for the purpose of piecing a broken end.

The invention will be fully described with reference to the accompanying drawings.

Figure 1. is a sectional elevation through the revolving ring and presser flier and ring rail. Fig. 2. is a plan of same. Fig. 3. is a sectional elevation of the revolving ring and presser flier detached from the ring rail. Fig. 4c. is a plan of the presser flier and its guide.

The revolving ring A is mounted to rotate on ball bearings in the ring rail B in the ordinary way. The interior of the ring A is of a diameter to allow the cop or bobbin on the spindle C to pass through it. Internally at one side of the revolving ring A a hearing, or bearings, a is provided, (preferably in the form of a sleeve), into which is fitted the upper member (Z of a flier D.

The presser flier D may be constructed of four members, a pin d to fit into the bearing a, a cranked central member al and a presser leg 03 with a guideeye (Z at its lower extremity, and a guide E to direct the yarn to the interior of the revolving rmg The presser flier D may be in one piece, forged or bent to shape, but it is preferable to build it in two separate parts, the pln d to rotate in the bearing, the

swiveling presser leg (Z with the crank 0Z affixed to the lower end of the pin cl, and the guide E in one piece with the pin d.

-The cranked member al is caused by the centrifugal motion to fly outward and cause the presser eye d to rest against the sur- The guide E at the top of the pin d is in the form of a small crank with a slotted eye 6 eccentric to the pin (1 and so positioned that the drag or pull of the yarn upon it tends to swivel the presser leg 03 inward and force the eye d against the spindle C or cop or bobbin thereon. The guide E swivels outward during the building of the cop or bobbin, and the pressure of the presser end is helped by the pull of the yarn, being least when the cop or bobbin is small and greatest when the cop or bobbin is full.

The rotation of the revolving ring A causes the presser leg d of the presser flier D to be swiveled so that the guide eye 01 at the free end is pressed into contact with the spindle C or bare tube at the commencement of the cop, and, as the cop or bobbin increases in diameter, the guide eye d swivels away from the center, but always remains pressed in contact with the surface of the cop or bobbin.

To insure steady running of the revolving ring A, I preferably balance the weight of the presser flier leg by means of a short counterweight a or thick leg, fixed to the revolving ring opposite to the presser flier leg. On the ring rail B a spring or spring lever G is mounted, and this lever carries a brake block H to bear against the periphery of the revolving ring A. The spring lever is extended in an upward direction and its upper end engages with an eccentric crank or cam K by which it can be forced forward to bring the brake block into action. The eccentric or cam K is connected to a handle or cranked lever is preferably extending above the thread board Z, by means of which lever the brake is put on or off as required to stop or start the rotation of the revolving ring A. In other respects,

the spindle G and spindle apparatus are mounted in the ordinary way with a lifting rail and a drag cord and Weight.

What I claim as my invention and desire to protect by Letters Patent is 1. In a spinning machine for jute, hemp, flax and other fibers, a spinning device comprising in its construction a revolving ring, wide enough to embrace the cop or bobbin and through which the cop or bobbin passes, and an eccentric centrifugal presser pivoted to the interior of the ring and extending downwardly therefrom, said presser being provided with a guide eye at its lower end by which the yarn is laid upon the cop.

2. In a spinning machine for jute, hemp, flax and other fibers, a ring, an eccentric flier and centrifugal presser pivoted to the ring and provided with a guide eye at its lower end, and with a thread guide at its upper end so placed that the drag or tension on the yarn tends to press the presser guide eye against the cop or bobbin.

3. In a machine for spinning jute, hemp, flaX and other fibers, the combination, With a revolving ring and a centrifugal presscr and guide eye pivoted thereto, of a spring controlled brake block, a spring connected therewith, and an eccentric and lever by which to apply 01 release the brake block.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.

GEORGE SHAW.
