    摘要： Hydroforming double wall tubular stock into an air gap tubular element comprising providing a plural wall tubular workpiece having at least an inner wall liner and an outer wall jacket having adjacent open axial ends, causing at least one of the jacket ends to extend axially beyond the adjacent liner end and to be flared outwardly, placing the workpiece into a first mold cavity of a size and configuration to result in the desired size and configuration of the liner, sealing the open ends of said liner, injecting hydroforming fluid into said liner to fill it and applying pressure thereto to expand the liner and jacket in the first mold cavity, releasing the pressure, placing the workpiece in a second mold cavity of a size and configuration desired for the jacket on a resulting air gap tubular element, providing hydroforming end closures to seal off the jacket ends, at least one of the end closures having an annular shoulder aligned with the flared extended jacket end radially outwardly offset from the adjacent liner end, pressing the annular shoulder directly against the flared jacket end to seal the flared jacket end between the shoulder and an anvil surface, injecting fluid into the workpiece to fill it and applying pressure to expand only the jacket.

    摘要： A pole for supporting a tool includes an elongate body extending along an axis. The elongate body defines a plurality of outwardly facing facets about the axis. The elongate body preferably includes a first tube and a second tube telescopically received within the first tube for adjusting a length of the pole. The two tubes are locked relative to one another by a locking mechanism that is fixedly coupled to the first tube with a detent engaging member that extends from the locking mechanism into engagement with a detent defined by the first tube. The locking mechanism preferably comprises a collet which is threadably coupled to a chuck that defines a plurality of outwardly facing facets. Rotation of the chuck causes the chuck to overlap the detent engaging member and to frictionally clamp the collet against the second tube.

    摘要： A cage for a paint roller is composed as a one piece, unitary construction having a plurality of projections carried by a barrel portion of the cage, the projections making pressure contact with the inside of the bore in the center of the cover so as to prevent the cover from walking off the cage in use. The projections are formed to adapt to structural irregularities in the cover bore. A cage and cover sub-assembly and a paint roller incorporating the above is disclosed.
