9166. Kirkpatrick, G. H. April 23. Spindle apparatus.-The interiors of the rings 1, Fig. 1, used in doubling and twisting frames are made conical, the upper and lower edges 4 being curved or rounded if desired. The drag of the yarn, which tends to pull the traveller 5 upwards, is counteracted by the centrifugal force of the traveller, which bears on the inclined surface 6 of the ring and is therefore forced downwards, the pressure on the bottom hook 7 being thereby relieved.
