MEANS FOR IMPARTING A FALSE TWIST TO TEXTILE ROVINGS File cli Jung 17, 1929 Patented Aug. 5, 1930 UNITED STATES PATENT OFFICE A GEORG KURT QUAAS, OF CHEMNITZ. GERMANY, ASSIGNOR T0 SACHSISCHE MASCHINEN- FABRIK VORM. RICH. HARTMANN AKTIENGESELLSCHAFT, OF CHEMNITZ, GER- MANY, A. JOINT-STOCK COMPANY MEANS FOR IMPARTING FALSE TWIST TO TEXTILE ROVINGS Application filed June 17, 1929, Serial No. 371,511, and in Germany September 24, 1928.
of a cap and to cause the tube to be held in' an annular driving member by its own weight only. This known arrangement is therefore suitable only for vertically arranged twist tubes. Moreover, it has the disadvantage that the tube must be taken out of the driving member in order to insert the textile roving into the tube during running.
According to the invention the drawbacks of this known arrangement are avoided by interposing between the driving member and the twist tube a clutch or coupling which enables the driving member to run freely during operation.
The drawings illustrate, by way of example, one construction embodying the features of the invention.
Fig. 1 is a diagrammatic sectional elevation showing the arrangement of an improved twist tube drive according to the invention between two pairs of rollers of a drawing device, and
Fig. 2 is a cross section through the twist tube on line IIII of Fig. 1.
In 'the drawings a, b designate a pair of feed rollers of a drawing device, 0 indicates the twist'tube. The twist tube is rotatably mounted in bearing members 0, e and is provided with a hook d. The twist tube is driven by a worm wheel 7 loosely mounted upon the tube. The free wheel coupling consists in the construction shown of a yoke-shaped clamping spring 71, located in an annular groove of the twist. tube '0 and secured to the tube by a screw or any other suitable means. The spring pressure. is so adjusted as to cause 7 the tube 0 to be normally carried by the roing 2' with his other hand through the tube and into the hook (Z. The hook catches the roving and feeds same to the next pair of rollers 70, m by which it is further drawn or stretched. The worm wheel f may be driven by a multiple worm g.
I claim:
1. In a device for imparting a false twist to a textile roving, the combination of a rotatable twist tube, a member driving said twist tube, and a yielding coupling interposed between said twist tube and said driving member.
2. In a device for imparting a false twist to a textile roving, the combination of a rotatable twist tube, a member driving said twist tube and a yielding coupling interposed between said twist tube and said driving member, said yielding coupling comprising a spring interposed between the twist tube and the driving member.
3. In a device 'for imparting a false twist to a textile roving, the combination of: a rotatable twist tube; an annular driving member loosely mounted upon said twist tube, and a yoke shaped spring adapted to transmit rotation from the driving member to the said twist tube and mounted in a peripheral groove between the twist tube and the driving member.
of rollers receiving the roving after the passage through the twist tube.
5. In a drawing mechanism for textile. rovings the combination of: a'pair of drawing rollers, a second pair of drawing rollers, a horizontal twist tube rotatably mounted between said two pairs of drawing rollers, a driving member for rotating said twist tube and a yielding coupling between 100 said driving member and said twist tube so adjusted as to normally drive the twist tube to allow same to be arrested by hand during continued running of the driving member, substantially as described.
Signed at Dresden, Germany, this 25th day of May, 1929.
