axis of cantilever form, such as may he adapted' to replace a godet and associated lap-displacing guide. vention will be apparent from the drawing and description thereof hereinafter.

1n the drawing, which is illustrative of the inventicn,

Figure 1 is a transverse cross-section of a prefer-'red embodiment of the reel. and

Figure 2 is a section on line II-II of Figure 1.

es shown, the reel is mounted for rotation about a: xed shaft 2 and comprises two sets of thread-carrying bars 3 and 4 respectively.

The set of bars 3 may be in the form of a cylindrical cage closed at one end by the reinforcing plate 5, provided with an annular rim S adapted to receive excess thread thrown oil the bars of the reel. The cage has a ange extending outwardly from the periphery of the bars and disposed away from the plate 5. The cage is secured to a web or plate E by means of cap screws 3- The hub I is secured to the driving spindle il by means of a nut il. A bushing i3 is provided Y between the spindle il and the iixed shaft 2 and is so constructed that the bars 3 are concentric with and rotate about the axis vof shaft 2.

The bars i are secured to supporting elements M which extend downwardly therefrom and are held against bearing elements l5 and I5 which are spaced axially from each other and are carried rotatably upon a central block or bushing il xedly secured to the shaft 2 by means of nut I8. The bearing surfaces of the central sleeve il' which carry the bearing members i5 and i6 are eccentric with respect to the axis of shaft 2. Preferably, the eccentrcity of the axis of bearing member I5 is close to 90 from the eccentricity of the axis of member i5 with respect to the shaft 2. The bearing member i5 may be provided with an arcuate groove comprising a plurality of seats l! :for receiving the oomplementarily formed convex portion lla of the supporting elements Il.

An annular plate has a plurality of radially This has the purpose of Other objects and advantages of the in 7 Claims. {Cl- 28-7.'1)

extending axially projecting lugs 2|. The radial portions of the supporting elements ld work slidably within the guideways formed between adjacent lugs 2l, thereby limiting angular movement of the bars d relative to the bearings i5 and i5. Garter springs 22 and 23 hold the base of thesupporting elements I in Contact with the bearing members i5 and i6 respectively.

A plurality of bosses 2d extending inwardly o the plate 8 carry the ring 25 supporting a plurality of pins 28 which project into apertures 2l in the plate 2d., The apertures El are elongated radially suiciently to allow for the relative eccentricity ci the pins 2S to the plate 2d during rotation thereof.

A exible seal 28, such as rubber, 'synthetic rubber, or the like, is secured to the flange 'l by means of cap screws S and to the bars d which have bosses 29 adapted to protrude through suitable openings in the seal' 2S, As shown in the drawing, the seal is entirely closed at one end and forms a tight housing about the driving parts and the bearings associated therewith, While permitting relative movement of the second set of bars d.

In operation, spindle il is driven, thereby driving the concentric cage of bars 3. The rotation of the concentric cage is transmitted to the eccentrically mounted bars by means of pins 26 engaging slots 2l in the plate 2D and by virtue of the guiding lugs 2l carried by the plate 2@ which prevent lagging of the bars 4. During rotation, bars alternately protrude and recede from the general periphery of the concentric cage of bars 3 and during such protrusion each bar d is rocked generally about an axis at the center of curvature of the curved foot portion 14a by virtue of the fact that bearing l E is eccentric with respect to bearing i5. Because of the eccentric relationship between bearings i5 and I5 and the shaft 2 the rocking motion picks up a yarn winding from a given position longitudinally of the bars 3 but deposits such winding in an advanced position longitudinally of the bars 3.

Although a cantilever form of reel is shown,

that is one which is supported at one end only, the reel construction is adaptable also to reels supported at both 'ends and capable of supporting a great number of windings spaced longitudinally of the bars thereof. As appears from the drawing and description thereof, the reel is of simple and inexpensive construction'and therefore most advantageously adaptable for use when a small number of turns are to be handled thereby.
