Abstract: A tube spinner for assembling vehicle tie rod assemblies is disclosed. The tube spinner includes a support structure for supporting a tapped tube, a rotating device for rotating the tube within the support structure into threaded engagement with one or more sockets simultaneously and a restraining structure for locking the sockets against rotation. In a preferred embodiment, a plurality of casters are provided for supporting a tube along a main axis of the tube. Generally U-shaped tracks are placed adjacent left and right ends of the tube to prevent rotation of sockets being attached to the left and right ends of the tube. A motor driven friction wheel is brought into engagement with an outer circumference of the tube for rotating the tube along its main axis and simultaneously threading the tube onto one or more sockets.

Abstract: In an air filter assembly a non-metallic air filter media is clamped between a pair of opposed metal end flanges, one of which is mounted by a threaded mounting rod in alignment with an opening through a horizontal panel. A metal sleeve integral with one of the end flanges stiffens the assembly and prevents the filter media from collapsing. The air filter assembly is used with numerous similar air filter assemblies to filter inlet combustion air for large gas turbine engines.
