Abstract: An electrical circuit connects an electric motor of a sump pump to a power source and controls the energization of a sump pump assembly. The assembly includes a motor circuit having a sump pump motor actuation switch and a main winding switch combined into switch assembly. The sump pump motor actuation switch actuates the main winding switch from a normally open position to a closed position, thus energizing the sump pump assembly.

Abstract: A terminal board assembly for an electric motor is described. The terminal board assembly is configured to mount inside an electric motor terminal or conduit box and includes a terminal board and a mounting bracket. The terminal board includes six terminal studs and three connecting bars extending between the terminal studs. Quick connect spade type connectors are coupled to the six terminal studs adjacent the bottom of the terminal board to facilitate quick and easy connection of the wire connection leads of an electric motor. The terminal studs and connecting bars permit a choice of “Y” or “Delta” voltage connections to the electric motor. The terminal board also includes a first and a second slot positioned at, and parallel to, opposing ends of the board. The mounting bracket includes a base portion and first and second side portions depending from opposing ends of the base portion.

Abstract: A method and apparatus are provided for disconnecting a starting winding of a single-phase motor during startup. The method includes the steps of disposing a heater element of a thermal switch in series with a main winding of the single-phase motor and disposing a set of contacts of the thermal switch in series with the starting winding of the single-phase motor.

Abstract: A submersible sump pump connected to a discharge pipe is disclosed. The sump pump includes a pedestal mounted above a sump. The pedestal includes a power cord, an indicator, and a high water alarm. The sump pump further includes a float switch connected to a styrofoam float which detects movement of the drainage level beyond a first predetermined point, a second predetermined point, and a third predetermined point.

Abstract: A linear motion to rotary motion converter. A moving cam carrier reciprocates with respect to a rotating turntable having a plurality of fingers, preferably roller bearings, secured to and extending from the turntable parallel to the axis of rotation of the turntable and radially spaced from the axis. The number of rollers extending from the turntable determine the number of indexed stop positions of the turntable. The cam carrier has two movable cams and also has two retaining members that are attached to the cam carrier and respectively spaced from the movable cams so as to define channels, between the respective pairs of movable cams and retaining members, through which the roller bearing fingers of the turntable are constrained to move. The curvature and shape of the channels determines the velocity profile of the turntable as the cam carrier reciprocates.

Abstract: An electric motor assembly has a motor housing, a stator mounted in the housing, a rotor rotatably mounted in the housing and disposed adjacent the stator, a pair of end shields mounted adjacent opposing ends of the motor housing having bearings disposed therein for rotatably supporting the rotor, a mounting bracket disposed in the housing, and a motor control component mounted in the bracket. The bracket has a one-piece, resilient body that is elastically deformable from a relaxed position to an expanded position, an engaging structure mounted on opposing portions of the body to secure the motor control component to the body, and a mounting structure that mounts the body in the housing. The bracket is mounted in the housing so that a surface thereof is disposed adjacent and interacts with an inner surface of the housing to prevent deformation of the bracket, thereby locking the component to the bracket.

Abstract: A motor assembly has a lead guard detachably disposed within a housing adjacent a conductor receiving opening formed therein. The lead guard defines a space within the motor housing into which a conductor may be routed. The guard has a generally flat portion and an upstanding portion connected at an angle thereto that extends around three of four perimetral edges of the flat portion. A mounting mechanism is provided to position the lead guard within the housing of the motor. A guide mechanism for guiding conductors fed through the conductor receiving opening into the space defined by the lead guard may also be provided. This guide mechanism may be attached to or integrally molded with the generally flat portion of the lead guard and may include an angled/ramped portion, the edge of which abuts the inner surface of the housing below the conductor receiving opening to prevent conductors from entering the motor housing and coming in contact with rotating components disposed therein.

Abstract: A motor has a shell formed to include an edge defining an opening that is either U-shaped or rectangular. A reversible apparatus has segments for mounting an overload protector having first and second body portions within the opening in the motor shell. The apparatus has a first profile for mounting the overload protector within a U-shaped opening in a motor shell so as to restrict movement of the mounting apparatus and overload protector assembly relative to the motor shell, and a second profile for mounting the overload protector within a rectangular opening in a motor shell so as to restrict movement of the mounting apparatus and overload protector assembly relative to the motor shell.

Abstract: A bushing for mounting an overload protector within an opening in a motor shell comprises segments adapted to be coaxially positioned around a portion of the overload protector. Mating features formed on the segments and protector restrict movement of the protector relative to the segments. Grooves formed on the segments secure the segments within the opening and restrict movement of the bushing and protector assembly relative to the structure. The bushing preferably comprises a pair of generally symmetrical segments connected together by an integrally formed hinge. The one-piece bushing is molded from a thermoplastic material, such as nylon. In one embodiment, the features which restrict axial movements of the overload protector relative to the segments are mating threads formed on a portion of the internal surfaces of the segments, and on opposing portions of the external surface of the protector.

Abstract: An electrical circuit for connecting an electric motor to an electrical source of supply comprising a double pole single throw switch having four quick-connect terminals thereon. Two of said terminals are connected to the electrical source of supply and the other two of said terminals connected directly to the windings of the electric motor. A centrifugal switch is provided, mounted internally of the housing of the electric motor on an insulated electric circuit board. The supply leads bypass the electric circuit board on which the centrifugal switch is mounted, thus minimizing the number of terminals and electric circuit connections and increasing the reliability and safety of the circuit.
