Specification of Letters Patent.

Patented Sept. 26, 1911.

Application filed August 17, 1910. Serial No. 577,637.

To all whom it may concern:

Be it known that I, JOHN E. BARBOUR,

a citizen of the United States, and resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Adjustable Ten sion for Bobbins for Spinning or Twisting Frames, of which the following is a specification.

The object of this invention is to provide an adjustable tension for bobbins of spinning or twisting frames whereby the drag on each bobbin may be instantly and readily removed when so desired.

In the accompanying drawings, Figure 1 represents in front elevation a portion of a spinning frame embodying my improvement, Fig. 2 is a vertical cross sectional view of the same, Fig. 3 is an enlarged detail front view of two adjacent bobbins and their spindles showing the drag reels on the left hand bobbin and applied on the right hand bobbin, Fig. 4 is a section taken in the plane of the line AA of Fig. 3, looking in the direction of the arrows, Fig. 5 is a vertical longitudinal section through the two bobbins and their adjacent parts, and Fig. 6 is a transverse section taken in the plane of the line B.-B of Fig. 4, looking in the direction of the arrows.

The spinning frame is denoted by 1 and each spindle rotatably mounted therein is denoted by 2. These spindles are driven in the usual manner from a suitable driving shaft 3 through the belt and pulley connections 4, 5, 6.

The bobbin mounted on each spindle 2 is denoted by 7 and it is provided with the following adjustable tension or drag: A circular block 8 surrounds the spindle within a housing 9, which block is interlocked with the bottom of the bobbin 7 by providing a plate 10 fixedly secured on the block 8 with dowels 11 projected upwardly into holes 12 in the bottom of the bobbin.

The leather flaps 13 which form the drag are secured at intervals around the periphery of the circular block 8. A spring band 14; is coiled around the block 8 within the housing 9, along the inner wall of which spring band the drags 13 are fitted to travel when the band is in its contracted posltlon. One end of this spring band is secured to a pin 15 carried by the housing 9 and the free end of the said band is fitted to slide along an inner portion of the band as the band is contracted and expanded. This band 14 is provided with a handle 16 which projects outwardly through an elongated slot 17 in the front of the housing 9. Shoulders 18, 19, are provided near the ends of the elongated slot 17 for retaining the handle 16 in its two positions against unintentional removal.

As the parts are arranged in the accompanying drawings, the spring band 14 is held in its contracted position when the handle 16 is at the limit of its movement to the left, and is held in its expanded position when the handle is swung to the limit of its movement to the right.

When the band is in its contracted position, it will coact with the drags 13 to exert a retarding tension upon the bobbin 7 and when the band is in its expanded position it will be released from its engagement with the drags 13 and thus permit the bobbin to rotate freely without any retarding tension thereon.

To permit two adjacent handles 16 to be freely moved from one to the other of their positions without interfering with each other, the handle of each alternate bobbin tension device is arranged in a plane above the handles of the remaining tension devices.

To insure the concentric relationship of the spring band 141 and the block 8, when the band is contracted the bottom of the housing 9 is provided with a circular shoulder 20 arranged to engage the inner wall of the spring band.

By the arrangement herein set forth, it will be seen that the tension on each individual bobbin may be applied or removed at pleasure without interfering with the tension'of the other bobbins.

It is evident that various changes might be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the structure herein shown and described, but

lVhat I claim is 1. A spindle, means for driving it, a bobbin mounted on the spindle, a drag flap fixed to rotate with the bobbin, an expansible and contractible band surrounding said drag flap and means for expanding and contracting said band.

2. A spindle, means for driving it, a bobbin mounted on the spindle, a drag flap fixed to rotate with the bobbin, an expansible and contractible band surrounding said drag flap and a handle attached, to said band and extending within convenient reach of the operator for throwing said band into and out of engagement with the flap.

3. A spindle, means for driving it, a bobbin mounted on the spindle, means for applying tension to the bobbin comprising a block surrounding the spindle, drags carried by the block, and an expansible and contractible band surrounding said block and means for expanding and contracting said band.

4. A bank of spindles, means for driving them, bobbins mounted on the spindles, means for applying tension to each of the bobbins, comprising a block surrounding each spindle, drags carried by each block and an expansible and contractible band surrounding each block, and means for expanding and contracting each of said bands.

5. A spindle, means for driving it, a bobbin mounted on the spindle, a plurality of drag flaps fixed to rotate with the bobbin, an. K expansible and contractible band surround JOHN E. BARBOUR.
