ABSTRACT:
An actuating selection device for a dobby mechanism for controlling movement of components used to affect movement of a heddle frame and a weaving loom wherein the selection device includes selector members which are pivotally mounted adjacent pole faces of an electromagnet and wherein a moveable armature is pivotally connected to the selector member and includes an outer extremity which is continuously urged into contact with a first of the poles of the electromagnet by a resilient element. The selector member is spaced from the electromagnet when no power is applied thereto and the selector member is moved toward the other pole of the electromagnet together with the moveable armature when power is supplied to the poles of the electromagnet with the movement of the selective member thus controlling the movement of the pair of components which affect the movement of the heddle frame.
