Abstract
In gripper shuttle looms for a shuttle box which contains a groove for receiving a gripper shuttle and which rotates 180.degree. to turn the shuttle around and has a braking member which cooperates with the groove to check the shuttle in the groove, and wherein said braking member moves away from the groove to permit the shuttle box to be turned and the shuttle to be picked: restraining means located in the groove for restraining the shuttle against lateral movement along the longitudinal axis of the groove during the shuttle box turning motion and which maintains the shuttle in the proper position in the shuttle box and allows the shuttle to be picked out of the shuttle box.
Claims9
Shuttle control apparatus for looms operating with gripper shuttles comprising:
- a. a shuttle box having an elongated opening along one side thereof and at least two generally opposed elongated surfaces extending inwardly from said elongated opening for guiding a shuttle therebetween;
- b. a braking member movable toward and away from said opening;
- c. means for moving said braking member toward said opening for engaging and braking a shuttle which enters said shuttle box and away from said opening for disengaging from said shuttle and thereby allowing said shuttle to be picked out of said shuttle box;
- d. means for positioning a shuttle to a predetermined location within said shuttle box after it has been braked;
- and
- e. a restraining member extending along a portion of at least one of said elongated surfaces for restraining a shuttle against sliding movement between said surfaces to maintain it in said predetermined location after it has been positioned and which allows said shuttle to be picked out of said shuttle box.
Gripper shuttle control apparatus comprising
- a. a rotating shuttle box comprising an elongated groove having a plurality of elongated surfaces for receiving a shuttle;
- b. a braking member movable toward and away from said groove;
- c. means for moving said braking member toward said groove for engaging and braking a shuttle which enters said shuttle box and away from said groove for disengaging from said shuttle and thereby allowing said shuttle to be picked out of said shuttle box;
- d. means for positioning a shuttle to a predetermined location within said shuttle box after it has been braked;
- and
- e. a restraining member having a shuttle engaging surface located within at least one of said elongated surfaces of said groove for restraining a shuttle against sliding movement within said groove to maintain it in said predetermined location after it has been positioned and which allows said shuttle to be picked out of said shuttle box.
