Abstract: A connector apparatus for an electrical appliance which includes a body having first and second spaced opposed faces. The body has a slot defined therein that passes completely through the body between the first and second opposed faces thereof. The slot has first and second spaced and opposed faces. The connector includes a generally planar metallic lug having first and second sides. The lug has at least first and second projections extending therefrom. The projections engage the body when the lug is disposed within the slot. In some forms of the invention the lug includes a third projection and the third projection also engages the body when the lug is disposed in the slot. The lug and the slot may be elongated and the respective directions of elongation may be substantially aligned when the lug is disposed within the slot.

Abstract: A motor and fan apparatus a centrifugal fan including a generally circular impeller having a plurality of generally radial vanes. The apparatus also includes a common shaft on which the impeller and the rotor are mounted in axially spaced relation. A circular pan shaped cover encloses the impeller and has a centrally disposed inlet and a wall disposed around the periphery of the impeller in spaced relationship from the periphery of the impeller. A fluid barrier is disposed axially adjacent to the impeller. The barrier and the cover collectively direct fluid flow from the periphery of the impeller in an axial direction parallel to the shaft. The apparatus includes a housing disposed axially adjacent to the barrier. The housing has a generally toroidal shaped part and a smaller generally circular shaped part, the generally toroidal shaped part and the generally circular shaped part are disposed in generally concentric relationship.

Abstract: A long-life motor brush holder which significantly minimizes contact of the coil portions of a ribbon spring with the holder and consequently reduces friction drag; the arrangement is such that at least two cylindrical surfaces forming part of the brush holder serve as line contact supports for each of the respective coil portions of the ribbon spring so as to produce minimal contact, the spring including a middle portion for residually engaging the brush to urge it against the motor commutator.
