Shuttle drive for a narrow ware loom

In a narrow ware loom having a frame, a warp shed, batten supporting means pivotally mounted on the frame, a batten mounted on said supporting means for vertical movement relative to said supporting means to any one of several positions, and a plurality of shuttles mounted on said batten for vertical movement therewith and for horizontal movement on said batten from a first side of said warp shed to a second side thereof, said shuttles being vertically spaced from each other so that only one of said shuttles is active by being aligned with said warp shed for each of the several positions of said batten, means for moving said active shuttle through said warp shed comprising:

• a. a drive for each of said shuttles, mounted on said batten for movement vertically therewith and longitudinally thereof between a first position and a second position, each of said drives being operably connected to its corresponding shuttle so that when the drive is in its first position, its corresponding shuttle is on the first side of said warp shed and when the drive is in its second position, its corresponding shuttle is on the second side of said warp shed;
• b. means for detecting whether the active shuttle is on the first or second side of said warp shed;
• c. a first actuator for moving the drive which corresponds to the active shuttle from its first position to its second position;
• d. a second actuator for moving the drive which corresponds to the active shuttle from its second position to its first position;
• and
• e. control means operatively connected to said detecting means for activating said first actuator when the active shuttle is on the first side of said warp shed for activating said second actuator when the active shuttle is on the second side of said warp shed.

In a narrow ware loom having a batten which is moved vertically to one of several positions in a pattern, a warp shed and a vertical row of shuttles mounted on said batten for vertical movement therewith and positioned so that only one of said shuttles is active by being aligned with said warp shed for each of the several positions of said batten, means for moving said active shuttle through said warp shed between first and second sides thereof comprising:

• a. a lug for each of said shuttles which move as a group along a first axis through a second actuating axis, which is transverse to said first axis, in the same pattern as said shuttles so that only the lug which corresponds to said active shuttle lies along said second axis and is the active lug, each of said lugs being independently movable between a first position and a second position along said second axis;
• b. drive means operatively connecting said lugs to said shuttles so that when any one of said lugs is in said first position, its corresponding shuttle is on said first side of said shed and when any one of said lugs is in said second position, its corresponding shuttle is on said second side of said shed;
• c. means for detecting whether said active lug is in said first or second position;
• d. a first actuator for moving said active lug from said first position to said second position;
• e. a second actuator for moving said active lug from said second position to said fist position;
• and
• f. control means operatively connected to said detecting means for activating said first actuator when said active lug is in said first position and for activating said second actuator when said active lug is in said second position.

In a narrow ware loom having a batten which is moved vertically to one of several positions in a pattern, a warp shed and a vertical row of shuttles mounted on said batten for vertical movement therewith and positioned so that only one of said shuttles is active by being aligned with said warp shed for each of the several positions of said batten, means for moving said aligned shuttle through said shed between first and second sides thereof comprising:

• a. a lug for each of said shuttles which move as a group along a first axis through a second actuating axis, which is transverse to said first axis, in the same pattern as said shuttles so that only the lug which corresponds to said active shuttle lies along said second axis and is the active lug, each of said lugs being independently movable between a first position and a second position along said second axis;
• b. drive means operatively connecting said lugs to said shuttles so that when said active lug is in said first position, its correponding shuttle is on said first side of said warp shed and when said active lug is in said second position, its corresponding shuttle is on said second side of said warp shed;
• c. means for detecting whether said active lug is in said first or second position;
• and
• d. actuator means and control means therefor which are operatively connected to said detecting means for shifting said active lug from whichever of said first and second position it is in to the other side of said positions.
