ABSTRACT:
There is disclosed several forms of adjusting mechanisms for a headlamp, or the like. Basically, the mechanism includes a one-piece molded housing member defining gear receiving chambers disposed transversely to each other with said chambers intersecting at a peripheral location. A first drive gear member is disposed in a first one of said gear receiving chambers, and a second adjusting gear member is disposed in the other chamber, with said gear member being engaged at the location where said chambers intersect. A drive member is coupled with the first, drive gear and extends from the housing. An adjusting screw is coupled with said second, adjusting gear for linear movement and extends from the housing for engagement with a headlamp. Accordingly, upon rotation of the drive gear linear movement will be imparted to the adjusting screw by the gear members, which linear movement produces adjustment of a headlamp assembly relative to the automobile frame. In several alternate embodiments, a cantilevered spring member is used to engage the gear members to prevent inadvertent rotation thereof.
