Abstract: A projectile accelerator has a coupling transmission articulated between a cam follower lever and a picking lever which has two end positions. The projectile accelerator also has an eccentric rocker on the drive shaft which cooperates with a tensioning lug on the accelerating shaft in order to carry out a return motion of the picking lever without need for a large angular movement of the cam follower lever. The picking lever is able to traverse large angles of movement while the cam following lever traverses reduced angles of movement.

Abstract: The picking mechanism is provided with two torsion bars. One torsion bar is stressed in order to accelerate a gripper projectile of the loom. The second torsion bar, upon release of the first torsion bar, is temporarily connected to the first torsion bar so that energy can be stored by the second torsion bar via a double-arm lever. During a return motion of the acceleration lever to a picking position, the second torsion bar is relieved of tension by delivering the stored energy to the drive shaft of the picking mechanism via the double arm lever. The picking mechanism thus uses only little energy.

Abstract: A picking device for the picking motion of a loom uses a pull string for delivering the picking energy to a pivot arm which is capable of being tensioned by way of a cam drive. The pull string can in principle be any elongate structure, e.g. a pull string of steel or a rope of high tenacity aramide fibers. The cam drive includes a toggle lever which is extended by a first cam and urged somewhat beyond its dead center, and which is urged by a second cam back over the dead center to initiate picking. A decelerating string is connected to the pivot arm to decelerate the pivot arm at the end of the pick.

Abstract: A cam drive is used to control the picking movement of the picking lever. The cam drive includes a dam disc which has a recess (or projection) which causes the lever to accelerate at the beginning of a pick and thereafter imparts a prestress to the spring before the cam follower of the lever moves out of the cam disc recess. A dog clutch is used to permit movement of the cam disc relative to the uniformly rotating drive shaft.
