Abstract
An encapsulated shuttle grip (B) is disclosed as including a molded housing (28) which co-operates with a shelf cut (C, C') in shuttle block (A) to interlock the shuttle grip positively and firmly in place. Compressible protrusions (58) carried on molded side wall ribs (54, 56) are compressed in lateral side cut grooves (66, 68) to resist rotation of gripping jaws (14, 16) about the axis of attachment bolt 38 during weaving and bobbin transfer along with other molded structural features of the molded housing 28.
Claims11
An encapsulated shuttle grip for use in a shuttle for holding a bobbin in a properly aligned position during weaving, said shuttle having a shelf cut formed therein in which said shuttle grip is received for attachment to said shuttle by means of an attachment bolt, said shelf cut having a side under cut groove formed in a side wall of said shuttle, said shuttle grip comprising:
- a pair of opposed rigid leaves having spaced apart gripping jaws, end shank portions, and intermediate curved portions joining said gripping jaws and shank portions;
- a molded housing having a forward nose portion;
- said end shank portions being encapsulated in said nose portion of said molded housing with said gripping jaws extending outwardly from said molded housing being free from said molded housing;
- and
- said molded housing including arcuately extended side walls encapsulating at least a portion of said intermediate curved portions of said shuttle grip leaves;
- a molded bottom rib extending outwardly from said arcuately extended side walls along at least a portion of said side walls rearwardly from said nose portion;
- and
- said bottom rib being receivable in said side undercut groove of said shelf of said shuttle for interlocking engagement therein resisting rotational movement of said shuttle grip about said attachment bolt.
An encapsulated shuttle grip for use in a shuttle having a shelf cut formed therein structure in which said shuttle grip is inserted and attached for holding a bobbin in a properly aligned position in said shuttle for weaving, said shuttle grip comprising:
- a pair of opposed rigid leaves having spaced apart gripping jaws, end shank portions, and intermediate curved portions joining said gripping jaws and said end shank portions;
- a molded housing having a forward nose portion;
- said molded housing having arcuate side walls extending rearwardly from said nose portion encapsulating at least a portion of said intermediate curved portions of said shuttle grip leaves;
- said end shank portions being encapsulated in said nose portion of said molded housing with said gripping jaws extending outwardly from said molded housing being free for receiving a butt end of said bobbin;
- a recessed side wall molded in said nose portion;
- a top nose rib molded in a top surface of said nose portion extending outwardly from said recessed side wall;
- a bottom nose rib molded in a bottom surface of said nose portion;
- arcuate side wall ribs extending along said curved side wall portions of said molded housing extending outwardly from said side walls;
- and
- a medial rib molded about said nose portion having planar sides and intersecting edges.
An encapsulated shuttle grip for use in a shuttle for holding a bobbin in a properly aligned position during weaving, said shuttle having a shelf cut formed therein in which said shuttle grip is received for attachment to said shuttle by means of an attachment bolt, said shelf cut having a side under cut groove formed in a side wall of said shuttle, said shuttle grip being of the type including a pair of opposed rigid leaves having spaced apart gripping jaws, end shank portions, and intermediate curved portions joining said gripping jaws and shank portions, a molded housing having a forward nose portion, said end shank portions being encapsulated in said nose portion of said molded housing with said gripping jaws extending outwardly from said molded housing being free from said molded housing, said molded housing including arcuately extended side walls encapsulating at least a portion of said intermediate curved portions of said shuttle grip leaves, wherein said encapsulated shuttle grip comprises:
- compressible rib means including a molded bottom rib extending outwardly from said arcuately extended side walls along at least a portion of said side walls;
- and
- said compressible rib means being compressed in said side undercut groove maintaining said shuttle grip firmly and positively in said shuttle against rotation.
