1. In a loom, a multicell shuttle box supported for movement to predetermined positions corresponding to required positions of the shuttle box two fluid operable, double-acting actuators, first means pivotally interconnecting said actuators, second pivotally supported means pivotally connected to the first means intermediate the pivotal connections of the latter to the actuators and pivotally connected to the shuttle box, said first means being movable under the control of said actuators to move the second means angularly about its pivot axis to in turn move the shuttle box to said required positions of the shuttle box, valve means connected to the fluid operable actuators, one for each actuator, said valve means being operable to control the passage of fluid to and from the respective actuators, a patterning device determinative of the position of the shuttle box at a given time in a cycle of operation of the loom, said patterning device being connected to the valve means and operative to condition the valve means to shift it to a position to accomplish movement of the shuttle box to said required positions at said desired times in the cycle, and a timing device operatively connecteD to the valve means operative to effect simultaneous operation of said conditioned valve means.

8. In a loom, a multicell shuttle box and lifter rod supporting the shuttle box for movement to predetermined positions corresponding to required positions of the shuttle box, two fluid operable, reciprocal actuators, a first rigid lever pivotally connected at its ends, respectively to the respective actuators, a second pivotally supported rigid lever pivotally connected at one end to the first lever intermediate its ends and at its other end to the lifter rod of the shuttle box, said first lever being movable by reciprocal movement of the actuators to move the second lever angularly about its pivot axis to in turn move the lifter rod and hence the shuttle box to said required positions of the shuttle box, valve means connected to the fluid operable, double-acting actuators, one for each actuator, said valve means being adapted to control the passage of fluid to and from the respective actuators, a patterning device for selectively determining the position of the shuttle box at a predetermined time in a cycle of operation of the loom, switches operable by said patterning device to condition the valve means for operation at said predetermined required time in the cycle of operation of the loom, and a timing device operable to simultaneously connect said switches to a source of power at a different time in the cycle of operation of the loom.

9. In a loom, a multicell shuttle box and lifter rod supporting the shuttle box for movement to predetermined positions corresponding to required positions of the shuttle box at appropriate times in the cycle of operation of the loom, means for effecting such movement comprising a pair of cylinder and piston assemblies, each embodying a piston rod, a rigid link pivotally connected at its respective ends to the respective piston rods, a pivotally supported rigid lever pivotally connected at one end to the rigid link intermediate its ends and at its other end to the lifter rod, said rigid link being movable by simultaneous movement of the piston rods to effect angular movement of the rigid lever and said rigid lever being operable by said angular movement to effect movement of the lifter rod and hence the shuttle box to said predetermined positions, valve means connected to each cylinder adapted to control the flow of fluid to and from the cylinders, electrically operable means connected to the valve means for effecting movement thereof, switches adapted to control the electrically operable means, a patterning device embodying means for presetting the switches so that when actuated they will effect movement of the shuttle box to the required positions, a power-supplying switch in the circuit and a timing device operable at predetermined intervals in the loom cycle to actuate said power switch.
