Abstract
Disclosed herein is a hair clipper comprising an outer housing of electrically insulating material, a motor located in the housing and including a field structure, an armature structure including a shaft, and bearing assemblies spaced axially of the armature structure and engaging the armature structure and the field structure for supporting the armature structure for rotation relative to the field structure, each of said bearing assemblies including a bearing and a bearing sleeve fabricated of electrically insulating material and located to isolate the bearing from one of the armature structure and the field structure, and screws mounting the field structure from the outer housing. Located at one end of the housing is a blade set connected to the field structure and including a first or stationary blade fixed relative to the field structure, a second blade movable relative to the first blade and including thereon a driven element formed of electrically insulating material and engaged by a drive member carried by the armature shaft to cause reciprocating movement of the second blade relative to the first blade in response to rotation of the shaft, which drive member is located in co-axial, surrounding relation to an eccentric end portion of the shaft and is supported by an annular bearing located between and engaging the end portion and the drive member to afford relative rotation therebetween.
