Abstract: A scrubber box is provided that includes a tank adapted to receive a substrate for cleaning, supports outside of the tank and adapted to couple to ends of scrubber brushes disposed within the tank, a motor mounted to each of the supports and adapted to rotate the scrubber brushes, a base to which the supports are pivotally mounted via spherical bearings adapted to permit toe-in of the scrubber brushes, a brush gap actuator adapted, via a crank and rocker mechanism, to substantially simultaneously pivot the supports toward or away from each other so as to permit the scrubber brushes to substantially simultaneously achieve or break contact with the substrate, and a toe-in actuator adapted to move two of the spherical bearings toward or away from each other so as to adjust a toe-in angle between the scrubber brushes.

Abstract: A brush wear indicator for a dynamoelectric machine, such as a direct current motor, comprises a fiber optic conductor coupling an emitter and a detector. The fiber optic conductor is fed into a brush holder where it is supported by a spring holder to which is attached a coiled biasing spring. The fiber optic conductor includes a region of separation where an element actuated by the biasing spring operates to complete or interrupt a light path between the exposed ends of the conductor at the separation. In one embodiment, an angulated tab secured to the spring operates as a shutter to move in and out of the spring holder to complete or interrupt the light path, while in a second embodiment, a rubber flexible diaphragm having an inwardly projecting body portion is actuated by the spring, by moving in and out of said region of separation to complete or interrupt the light path.

Abstract: A brush wear detector assembly for the brushes contacting the rotating commutator or slip rings of a dynamoelectric machine includes a light interruptor member located in a housing attached to the brush holder with the light interruptor being biased by a compression spring which operates to push the light interruptor against the side of the brush. The light interruptor includes an aperture, or other discontinuity, which is located adjacent the separation of a fiber optic conductor. During a usable condition of the brush, a light path is completed through the aperture between the exposed ends of the fiber optic conductor; however, for a worn condition of the brush, it is forced laterally into the brush holder behind the end of the brush causing the light path to be interrupted whereupon a signal indicative of a worn condition of the brush is generated. Alternatively, the aperture or conductor positioning could be such that at worn brush condition a light path is established.

Abstract: Apparatus for retaining a coil in position with respect to a pole and electric motor, the pole forming a substantially rectangular shaped projection internally of the motor, having a width approximately the same dimension as the width of a central aperture of the coil through which the pole is to project, comprising a generally L-shaped member having one arm adapted for sliding into a space between a pole and the coil and a second arm bent to overlay a surface of the coil for pressing the coil against a frame of the motor. The pole is provided with a retention structure running longitudinally along each side such that the arm of the L-shaped member lying in the space between the pole and coil can grasp the retention structure so as to be retained in a fixed position.

Abstract: A spacer for fixedly positioning a winding with respect to the ends an associated core in an electromagnetic apparatus. The spacers are formed of a relatively stiff sheet material with high electrical insulating characteristics and are of a generally rectangular configuration bent to form a V-shaped spacer. The spacers contact ends of the cores and corresponding inner surfaces of their associated windings to hold them in a predetermined position and to define an insulator creep path. The spacers are described in conjunction with a dynamoelectric machine having a pole spaced from windings through use of the insulating spacers.

Abstract: A winding form made of readily removable material for use in positioning electric windings in predetermined spaced relationship on an electrical apparatus. A method for mounting a winding on an electrical apparatus using the winding form of the invention is also disclosed wherein the form is mounted in a preselected position on the apparatus, windings are wound around the form, then the form is removed from between the apparatus and the windings by either dissolving it in a suitable solvent or by melting it effectively to dissolve it.

Abstract: A brush wear indicator for a dynamoelectric machine including a brush holder for slidably mounting a brush, a self-winding, brush-biasing spring having one of its ends mounted in fixed relationship on the brush holder, in combination with a circuit board having a dielectric member on which a plurality of electrical contacts are mounted in spaced relationship to be electrically engaged by the spring when it is fully extended to accept a new brush in the brush holder. As the brush wears, the spring moves downward to continue exerting a biasing force on the brush, and sequentially moves out of engagement with the contacts on the circuit board responsive to predetermined degrees of brush wear occurring. Such movement of the spring causes the contacts to be sequentially disengaged from the spring, thereby causing associated signal means, such as glow lamps, to be de-energized thus indicating the occurrence of the predetermined degrees of brush wear.

Abstract: An armature lamina for a dynamoelectric machine characterized by having a plurality of equally spaced winding slots formed around its periphery so that the winding-receiving gap, or mouth, of each slot is positioned near one side thereof, rather than being positioned at the center of the slot. In a preferred embodiment, the winding slots are divided into groups such that half of the slots have their respective mouths positioned adjacent the leading slot side while the remaining half of the slots have their respective mouths positioned adjacent the trailing slot side. This characteristic off-centered arrangement of the respective slot openings enables a maximum number of energizing windings to be positioned in each slot when the laminae are stacked on a spindle and wound with coils of insulated magnet wire to form a random wound armature. Alternative embodiments are provided for short pitch and double fly wound machines.
