ABSTRACT:
A quick-release fastening device for securing a bobbin spacer to a spindle on which bobbins are axially mounted while allowing the absorption of thermal expansion of the bobbins, which device comprises a locking rod adapted to be firmly secured, at one end, to the spindle. The rod has an annular groove therein. Upper fastening means includes a sleeve slidably fitted on the locking rod which sleeve has ball-holding holes at the position corresponding to the annular groove and balls are located in the holes. A locking slide member is mounted on the sleeve which member is slidable freely along the sleeve and has a recess at its inner side. A compression spring is disposed in the recess and serves to cause sliding of the slide member. A flange member is provided surrounding the uppermost part of the sleeve above the recess and is fitted in the locking member. The balls are held between the annular groove of the locking rod and the slide member. The thermal-expansion-absorbing means includes a slidable ring mounted on the outer periphery of the sleeve which ring is adapted to be firmly secured onto the bobbin spacer, a spring-supporting member secured to the sleeve above the slidable ring, and a compression spring interposed between the slidable ring and spring-supporting member, the spring serving to absorb thermal expansion of bobbins by its resiliency. When the slide member is slid up or down, the locking rod can be released from or fastened to the entire assembly consisting of the sleeve and associated components by the disengagement or engagement of the balls.
