Abstract: A housing assembly for a writing instrument is provided comprising a long, hollow barrel member and a ferrule member assembled in end-to-end relationship to afford an inner chamber for a reservoir of marking fluid. A writing nib projects from the ferrule and extends into the reservoir.The ferrule member and the barrel member have adjacent skirt portions in telescoping assembled relation for normally mechanically urging the ferrule and barrel together in axial alignment. Additionally, the skirt portions, when moved longitudinally one into the other, afford fastening means, sealing means and means for constraining relative rotation between the assembled ferrule member and the barrel member thereby providing a securely sealed and easily assembled housing for a writing instrument.

Abstract: A tire changer including a base having a lower extremity to support the base on an underlying surface, a tabletop having wheel grippers, a pivot mounting the tabletop on the base for pivotal movement about a generally horizontal axis between a generally horizontal, tire changing position and a generally vertical, wheel loading and unloading position whereat the wheel gripper is in sufficiently close proximity to the underlying surface supporting the base so as to be engageable with and securable to an upright wheel and tire on an underlying surface, a motor for selectively pivoting the tabletop between the two positions thereof, a bead loosening device connected to the base and defining a tire and wheel receiving space for receipt of an upright tire and wheel, the bead loosening device including at least one bead loosening shoe generally horizontally movable across the space in a direction generally transverse to the horizontal axis.
