DEFINITION

Classification: 83/386

(under subclass 385) Device in which the force transmitting means between tool and clamp comprises a resilient, deformable or slippable element.

(1) Note. See (1) Note under subclass 387.

(2) Note. The yieldable element may be included in the drive as a mere safety feature to prevent excessive overload strains, or it may yield during normal conditions of machine operation, within the purview of the definition of this subclass.

(3) Note. A frangible element, such as a shear pin, constitutes a yieldable drive element for the purposes of this subclass.
