Abstract
A stabilizer for the spring fixed in a shuttle having opposed laterally flexible spring steel jaws for releasably holding a weft bobbin within the shuttle. The stabilizer is supported by the shuttle spring in operative association with the jaws thereof and serves to control the amount of lateral flexing movement of the latter during removal of a spent bobbin from and the transfer of a new bobbin into a shuttle.

A stabilizer for a shuttle spring of the type having a U-shaped shank portion with opposed laterally flexible spring steel gripping jaws for releasably holding a weft bobbin therebetween, said stabilizer comprising:
- a. a body portion;
- b. a rib member (28) forming one end of said body portion having a lateral dimension of a width to be rigidly held by the shank portion;
- c. means interconnected with and spaced from said rib member defining the opposite end (29) of said body portion having a lateral dimension of greater width than said rib member;
- and
- d. stop surfaces (33-34) defining the sides of said opposite end of said body portion for engaging the gripping jaws at locations intermediate their ends and the shank portion during bobbin replenishment to prevent inward flexing thereof beyond a predetermined position.
