  • Patent number: 11794802
    Abstract: An adjustment actuator assembly for a vehicle steering system includes a leadscrew having a threaded outer surface and at least one pocket recessed radially inwardly from an outer diameter of the threaded outer surface. The adjustment actuator assembly also includes a nut having a threaded inner surface engaged with the threaded outer surface of the leadscrew, the nut axially moveable along the leadscrew during rotation of the leadscrew. The adjustment actuator assembly further includes a travel stop limiter operatively coupled to the nut, the travel stop limiter having a leg extending through an opening of the nut and spring biased into contact with the threaded outer surface of the leadscrew and moveable into the pocket of the leadscrew to limit axial translation of the nut.

  • Patent number: 11167394
    Abstract: A pipe alignment clamp for use in pipe fitting/fabrication applications. The pipe alignment clamp has a generally circular frame with at least one hinge therealong to enable the clamp to be opened and subsequently secured around a pair of pipe segments and/or fittings to be joined. Threaded support members are positioned along the frame in spaced apart fashion, and extend outwardly from each side of the frame. The support members are used to support alignment screws that can be independently repositioned radially towards and away from the pipe segments and/or fittings to be joined, thereby enabling the alignment clamp to accommodate a wide variety of different shapes and sizes of pipe segments and fittings, and requiring a minimum length of pipe segment to operate. The adjustment screws may be manipulated by hand, or by a separate alignment screw tool, which may be included as part of a pipe alignment kit.

  • Patent number: 8573577
    Abstract: A point-welding clamp structure for side by side tightly clamping and locating different plate-shaped metal pieces in their true relative positions so as to facilitate the point-welding operation. The point-welding clamp structure includes a body section and a base section for clamping the different metal pieces. A second adjustment section is disposed on the body section and a third adjustment section is disposed on the base section. By means of operating the second and third adjustment sections, the metal pieces with different thickness can be securely clamped and located by the point-welding clamp structure.

  • Patent number: 4281827
    Abstract: An improved miter box allows crown molding to be cut in the same orientation in which it will be installed to assure a perfect mitered joint. The miter box holds a longitudinal workpiece so that it can be cut by a cutting apparatus at a first angle measured in a plane parallel to the longitudinal axis of the workpiece and at a second angle measured in a plane perpendicular to the longitudinal axis of the workpiece. The miter box has a base, a backboard mounted perpendicularly on one edge of the base, a cutting apparatus guide for guiding the cutting apparatus to cut the workpiece at the first angle, a first wedge apparatus mounted on the backboard having a lower surface at the second angle to the backboard, and a second wedge apparatus mounted on the base having an upper surface at the second angle to the backboard.
