Abstract: A radiographic device may include a base, a support arm pivotably coupled to the base and defining a support axis, the support arm being movable between a normal position and two diametrically opposed, laterally rotated positions, and a radiographic head coupled to the support arm. A tension assembly may be coupled to the base and a linkage system may extend between the tension assembly and the support arm. The linkage system may include a hub and linkage may be partially entrained with the hub. The linkage may include a pivot point joining the linkage proximal end and the linkage distal end. When the support arm is in the normal position, the linkage may be positioned with respect to the hub so that the lateral reference line also intersects the linkage pivot point.

Abstract: A bulb shield for use in an automotive headlamp assembly, and a method for making same. The bulb shield includes a cup portion and a portion which extends from the cup portion and is configured for mounting to a reflector of the automotive headlamp assembly or to another, proximate structure. When the bulb shield is mounted, the cup portion is preferably generally horizontally aligned with a headlamp bulb in the automotive headlamp assembly, thereby eliminating a “hot spot” which would otherwise be viewable when looking into the headlamp beam. Preferably, at least a portion of the cup portion of the bulb shield is electro-formed. Such a bulb shield is relatively inexpensive and easy to make, yet can withstand the high temperatures which are typically experienced in an automotive headlamp assembly. Additionally, such a bulb shield can be inexpensively provided, yet meet precision requirements.

Abstract: A device for adjusting the position of a headlamp reflector of a headlamp assembly. The device includes a housing and a directing member, such as an adjustor screw, which generally extends from the housing. The directing member has an end which is engageable with the headlamp reflector of the headlamp assembly, and an opposite end which is configured to receive a driver generally coaxial with a longitudinal axis of the directing member. The directing member provides that rotation of the driver about an axis which is generally coaxial with the longitudinal axis of the directing member causes the directing member to translate relative to the housing thereby causing adjustment of the position of the headlamp reflector which is engaged with the first end of the directing member.

Abstract: A headlamp adjustor which includes an adjustor output shaft that is engageable with a reflector of a headlamp assembly. The adjustor output shaft extends from a housing, and a worm gear generally in the housing is spur gearably engaged with the adjustor output shaft. Drive structure is engaged with the worm gear such that actuation of the drive structure causes at least a portion of the drive structure to thread into at least a portion of the worm gear, thereby causing the adjustor output shaft to translate relative to the housing and adjust the position of the headlamp reflector.

Abstract: A headlight adjuster for adjusting the aim of a headlight. The adjuster provides relatively fine incremental control of headlight motion in response to relatively coarse adjustment of a drive shaft. This functionality is achieved by use of a link having two gear driven sections. A first helical section engages a drive gear which serves as the mechanical input. A second threaded section of relatively fine thread engages a nut fixed in the adjuster housing. The link is carried in a linear bearing which allows free rotation of the link in accordance with the mechanical input. The degree of translation, however, is controlled by the pitch of the thread engaging the nut.

Abstract: An adjuster for adjusting a headlamp component along mutually perpendicular coordinates includes an eccentric connected to a threaded shaft and adapted to be rotated to adjust the headlamp component along one coordinate when a toothed wheel on the shaft is turned by a Phillips screwdriver. By using the screwdriver to turn a second toothed wheel on the shaft, the shaft and the eccentric are moved linearly to effect adjustment of the headlamp component along the second coordinate.

Abstract: The reflector of the headlamp is pivotally supported within a housing for vertical tilting about a horizontal axis and for horizontal pivoting about a vertical axis. A bubble level is carried by the reflector and may be adjusted relative thereto to a level position after the reflector has been tilted about the horizontal axis to establish proper vertical aiming of the headlamp beam. A horizontal indicator is located at the same inspection position as the bubble level and may be adjusted to a zero setting after the reflector has been pivoted about the vertical axis to establish proper horizontal aiming of the beam. Part of a mounting platform for the bubble level also serves as part of an indicating scale for the horizontal indicator.

Abstract: A vehicular headlamp component is pivotally adjusted in response to back or forth movement of an adjusting link extending through an opening in one wall of a two-component housing of an adjusting device. Back and forth movement of the link is produced by a gear driven bushing which is threaded onto the link. An O-ring encircles the link between the bushing and the housing wall and is adapted to be compressed against the wall and the link thereby to seal the opening in the wall and prevent contamination from passing through the opening and into the housing of the headlamp. Compression of the O-ring is effected by camming the bushing toward the housing wall as an incident to assembly of the two housing components with one another.
