Abstract: A system and method are provided for levelling suspended luminaires. The system includes a shuttle and a thumb wheel disposed in a housing. The shuttle includes a gripper for securing the cable wires that attach to the luminaire. A rotational movement of the thumb wheel is translated to linear movement of the shuttle within a slot of the housing to allow adjustment of an attachment point of the cable wire relative to the rest of the luminaire to enable tool-free levelling of the luminaire.
Abstract: An adjustable wrench comprising a head portion defining a stationary jaw and a mounting slot in the head portion extending in the direction of a transverse axis thereof, and a movable jaw member mounted to the head portion for reciprocating movement along the transverse axis. The movable jaw member includes a movable jaw in alignment with the stationary jaw and a gear rack having a toothed segment. The gear rack is slidably mounted in the mounting slot. The adjustable wrench further comprises a bearing guide device including at least two bearing guides disposed in a space between an outer wall of the gear rack and an inner wall of the mounting slot so that at least one of the bearing guides is arranged on one side of the gear rack and at least one of the bearing guides is arranged on the opposite side of the gear rack.
Abstract: An engine tilting tool used to tilt transversely mounted General Motors engines includes a tubular bracket member which receives a telescoping tubular member that is driven telescopically by means of a drive rod mounted on the bracket member. The bracket member is attached to the vehicle engine compartment in place of one end of the “dog bone” strut engine support and the telescoping tubular member is attached to the engine in place of the opposite end of the strut engine support. A nut is used to adjust the position of the telescoping tube relative to the tubular bracket member to thereby effect tilting of the engine.
Abstract: An adjustable jaw double ended wrench, where each set of jaws is gear operated. Each end wrench is adjustable, both individually and independently; the open end wrench driven by a spiral grooved shaft with beveled gears; the closed end wrench, linearly actuated by a direct driven spiral grooved shaft. At one end of the wrench is an adjustable open end wrench with a set of parallel jaws, useful in tightening or removing hex fasteners, such as hex and machine screw nuts, and cap screws. The other end, an adjustable closed end wrench for tightening or removing hex head cap screws, hex-head nuts, as well as for clutching other work. This wrench end is particularly well suited for use in areas that are blind to the user, especially in such applications as in automotive assembly and repair, ship inboard motor repair and numerous other applications of assembly and disassembly of items that may not be within the view of the user.
