Abstract: A combined commutator brush retainer clip and electrical connector includes a main body portion and a terminal portion. The main body portion has a recessed portion with a plurality of dimples therein. A commutator brush is electrically connected to a brush holder sleeve, and the brush holder sleeve is, in turn, clampingly engaged to the commutator housing with the retainer. The brush holder sleeve is disposed within the recessed portion of the retaining clip and is frictionally engaged by the dimples. The terminal portion of the retainer engages a corresponding terminal member on the motor stator such that an electrical connection is established between said commutator brush and said stator by way of said retainer.

Abstract: An apparatus and method is provided for introducing slack into a coil wire prior to termination. A stator having a volume of coil windings has a terminal board mounted thereon. Means for introducing slack in the coil wire includes a terminal receiving cavity located in the terminal board. A portion of the coil wire is passed across the cavity and a terminal is inserted therein, thereby crimpingly engaging the wire. The wire is simultaneously passed over a spacer which extends laterally across the cavity. When the spacer is subsequently removed a loop of slack remains in the wire.

Abstract: A commutator end bracket formed from a singular piece of sheet metal. The bracket is formed to include bases for mounting the commutator end bracket to a motor. Windows are punched into side pieces of the bracket for receiving brushes for communication with a commutator. The brushes are retained by a clip received within channels formed along the edges of the side pieces. A bearing is received within a housing drawn from a top plate of the bracket. The bearing is maintained within the housing by means of a spring clip which mates with portions of the top plate.

Abstract: A by-pass vacuum motor assembly wherein the motor cooling fan is positioned in an opening at the bottom of the motor band and immediately above a flat plate portion of the fan housing bracket. The flat plate portion functions as a plate diffuser, redirecting air drawn through the commutator end bracket and across the motor internals into a radial exhaust between a bottom portion of the band and a top portion of the fan end bracket. The invention also includes a brush holder clip passing through a vertical opening in the commutator end bracket and engaging a collar on the brush mechanism. The brush mechanism passes through a horizontal opening in the commutator end bracket which intersects with the vertical opening. Armature grounding is achieved by a disk maintained in a recess in the commutator end bracket and urged by a spring against the bearing receiving the motor shaft.

Abstract: A motor-fan unit for a wet pick-up type of vacuum cleaner comprising a fan-section and a separately ventilated motor section. A motor-end bracket in the motor housing structure serves as a common end wall with the fan section and carries a bearing for the common shaft of the motor and fan. A baffle carried by the motor-end bracket within the fan section has an apertured central portion, at least partly enclosing the bearing, to provide a passage-way for high velocity air sealing the bearing from detergent-containing cleaning liquid entrained in working air drawn into the fan section. A normally closed check valve at an inlet to the sealing air passageway inhibits back-flow of either air or liquid through the inlet but permits such sealing air to serve as cooling air when the entrance of working air into the fan section is impeded.

Abstract: A wet pick-up type vacuum motor fan unit with a separately ventilated motor section and a motor end bracket serving also as a support for, and part of a discharge end housing wall for, the working air fan section, has on the bracket fanward face a centrally apertured metal disk plate defining a flow space or path for bearing sealing air flow from ambient air inlets external of the motor section to a central discharge into the inlet eye of an auxiliary fan clamped on the shaft back-to-back with a larger diameter working air centrifugal fan adjacent the end bracket.
