Abstract: A method of assembling a motor to an object, a motor housing, and an electric motor are disclosed, each of which uses a hollow fastener to secure the motor housing to form an integral unit. Thru bolts are retained within the hollow fastener such that the thru bolts may thereafter be utilized to mount the motor to another object without requiring disassembly of the motor. Additionally disclosed are retainers for securing the thru bolts within the fastener during those time periods between motor assembly and assembly of the motor to an object to which it is to be mounted.

Abstract: The tension of a windshield wiper is adjusted by turning a nut which adjusts the rotational tension of a spring on the arm. The positioning of the nut is fixed by a second nut, a spring also forces the arm into a detent, holding the arm away from the windshield.

Abstract: An improved sealing and attachment means between a rubber boot (20) for a powdered door lock (4) and its actuator rod (10), which allows, not only radial, linear movement of the rod with respect to its power motor, but also rotational movement of the rod within its attachment to the boot, allowing such rotation without significantly distorting the boot. Two, axially spaced grooves (13 & 14) are located on the exterior surface of the rod at the area (15) to which the boot is to be attached, while two longitudinally spaced annular beads (22 & 23) are provided on the interior surface of the end portion (21) of the boot, which beads will be located between, but not in, the grooves. Two ring clips (16 & 17), serving as radially extended retainers, are placed in the rod grooves, fixedly positioning the attachment end portion of the boot longitudinally between the grooves. A gap (18) allows the ring clip to be laterally clipped onto its respective groove.

Abstract: A powered actuator (1) for driving mechanisms that open and close convertible tops, sunroofs, windows and the like in motor vehicles; in which actuator (1) has a manual override feature allowing actuator (1) to be easily operated by hand should the electrical power system of the motor vehicle fail, yet the manual override feature does not require calibration or periodic adjustment.Actuator (1) includes actuator housing (2) having an attached motor having first gear (28) driven by the motor armature, output shaft (18) having driven gear (12) mounted thereon, insert cushion (10) being engaged with driven gear (12), and removable plate (6) being installed upon plate end (42) of output shaft (18). Actuator (1) is manually operated by removing removable plate (6) thereby disengaging driven gear (12) from output shaft (18) and then manually imparting rotation to plate end (42) of output shaft (18).

Abstract: An electric motor actuator (10) has an armature shaft (18) with a damper (28) comprising a collar (30) fit tightly into a housing (14) and slid over the shaft (18). The damper (28) has a plurality of spring-like fingers (32) protruding from the collar (30) supporting tghe shaft (18) intermediate to its journaled extreme ends (24, 26) by exerting sufficient force to damp vibrations caused by rotation of the shaft and counter-act the tendency of the shaft to move radially. The damper (28) is formed of a resilient, self-lubricating material impervious to grease, so as to isolate electrical motor parts from greased gears driven by the armature shaft.

Abstract: A double insulated starter motor for use with power equipment. A combination of insulating members about a motor together with various insulating members for electrically isolating the starter gear from the motor are collectively utilized to effect double insulation of a starter designed for use with power equipment, especially outdoor equipment subject to adverse environmental and operating conditions.

Abstract: A non-commutated linear motor particularly suitable for use as an electric door lock actuator for an automobile is disclosed. The linear motor may include a series of cup-shaped portions each having a winding appropriately connected to provide the desired travel stroke, in a direction determined by polarity of D.C. power applied to the winding, and power for the linear motor or a segmented armature designed to achieve the same flexibility in motor design and assembly.

Abstract: An electric motor including an insulating retainer for securing permanent magnets in position and providing secondary insulation for a double insulated motor. The insulating retainer includes a dielectric tubular body sized to fit within the motor housing, magnet retainers affixed to the tubular body for securing permanent magnets in position and alignment means for aligning the retainer within the motor housing to place the magnets in the optimum position within the motor housing.

Abstract: A door lock system for a motor vehicle including a latching and locking means is disclosed. A cam means is driven about a pivot point by the engagement of gear projections with a slot in the cam means to effect locking and unlocking of the door lock. The cam means and the gear projections are separated once the door lock is in the locked or unlocked position to allow the door lock to be manually displaced without necessitating the rotational translation of the gear or the electric motor driving the gear.

Abstract: A contact and terminal assembly having a block member, a conductor, and a securing member is disclosed. The block member and the securing member each define coacting curved surfaces between which the conductor is secured. The coacting curved surfaces define an appropriate angle for bending the conductor such that the conductor may serve on one end as a contact and at the other end as a terminal to which an electrical connection may be made. The block member, conductor, and securing member each include appropriate tabs and shoulders such that the three items may be appropriately interlocked to be affixed to each other.

Abstract: A dynamoelectric machine including a brush holder having a displaceable section for positioning the brushes in a mounting position is disclosed. The displaceable section is located to secure the brushes in a mounting position and said displaceable section being separated during assembly to allow the brushes to be displaced inwardly to engage the commutator in the final assembled position. Several embodiments of displaceable sections are disclosed.

Abstract: A brushless DC motor control circuit for efficiently controlling motor speed is described. A digital circuit for providing centered pulse turn-on during that period when the specific winding is capable of providing torque for the desired direction of rotation to the rotor is described. Each phase has its own timing circuit including an initial delay-time interval and an on-time interval. These time intervals are set to obtain desired motor speed and efficient motor operation.

Abstract: An electric door lock actuator and door lock and latch mechanism are disclosed having manual and electric driven locking means. A combination of a lost motion coupling and resilient spring means for driving the motive means to a neutral position are utilized to effectively isolate the electric motor and gearing from the locking means such that the locking means may be operated manually without back-driving the electric motor and intermediate gearing. A specific rack defining a portion of the lost motion coupling together with a pair of springs mounted to engage a shoulder extending from a rack are disclosed to achieve the above function.

Abstract: A shift actuator for a vehicle transfer case includes a bidirectional electric motor for positioning gearing in the transfer case. An indicator mechanism associated with the drive train between the motor and the transfer case provides electrical signals indicative of the actual position in, and thus operating state, of the gearing in the transfer case. A selector switch provides electrical signals indicative of a desired operating state of the transfer case gearing. An electronic control is responsive to an input from the selector switch and to the indicator mechanism for effecting rotation of the motor in a predetermined one or other direction to attain the desired operating state. The indicator mechanism includes a contact plate, which rotates with the drive train, and a set of stationary contacts. A conductive pattern on the contact plate identifies the positioning of the operating states of the transfer case gearing.
