Abstract
An apparatus for braking and positioning a spinning or twisting spindle with the spindle rotor in a specified position, having a spindle brake which engages with a rotary part, preferably a wharve, of the spindle, and, separate from said brake, positioning means comprising an additional braking surface which extends over part of the periphery of a rotary part, preferably a wharve, of said spindle and up to which an additional brake member is movable. The apparatus provides a more simply constructed braking and positioning means where it is permissible for the spindle to be stopped within a certain angular range about a prescribed central position. In the illustrated embodiment, a spindle brake proper comprises shoe means 7 engageable with an inside periphery of a skirt 5 of wharve 4, and there is provided positioning means comprising an additional braking surface 9 which preferably extends over an angle from 15.degree. to 30.degree. and which is engageable by an additional brake shoe 12. Movement of a toggle device 14, 15 downwards to a substantially straight position applied the spindle brake proper to stop the spindle rotor, and also causes, through fluid operated means, inward movement of shoe 12. Further movement of the toggle device 14, 15 to a downwardly-angled position releases the spindle brake proper, and the spindle rotor is held in a required position when surface 9 is opposite the inwardly-moved shoe 12.
