Abstract: A glass cutter having a cutting wheel rotatably mounted at one end thereof. A cutting fluid reservoir is situated within the tool housing at the end remote from the cutting wheel. The cutting wheel is mounted on a support member which is spring biased to provide a constant cutting pressure. A part of the wheel supporting member cooperates with the interior of the housing to form a valve which allows cutting fluid to flow through the wheel when the wheel is displaced against the action of the spring toward the housing during a cutting operation. A wheel cover pivotably mounted to the housing adjacent the cutting wheel has a closed position in which it protects the cutting wheel, and an open position in which the cover acts as a cutting guide.

Abstract: A bracket assembly has a rod with a hook, which may be a swivel hook, affixed to one end. A wall bracket is held on the other end of the rod, for maintaining any of a plurality of given angular displacements, in a horizontal plane, between the rod and a wall. The hook end of the rod is supported by a chain, cord or the like extending from a fitting on the wall above the wall bracket to a support point on the rod further from the wall than the hook. The wall bracket may have a pivot joint with a plurality of fixed pivot positions changeable only by lifting the rod, or it may be comprised of a block having a plurality of horizontal holes at determined angular displacements.

Abstract: A locking pulley assembly includes a pulley adapted to be affixed to a surface, a pull handle, a swivel hook, and a cord extending between the swivel hook and the handle around the pulley wheel. The pulley includes a unitary pulley wheel having locking grooves and coaxial frustoconical bearing surfaces, the pulley wheel being mounted for rotation in a unitary frame having inwardly facing frustoconical bearing surfaces engaging the bearing surfaces of the pulley wheel to form a rotatable joint. The handle is comprised of a cylindrical member having a central axial hole with reduced diameter at its central portion for holding a knotted end of the cord. The handle also has a slot at each end thereof of width slightly less than the diameter of the cord, to enable the handle to hold the cord. The swivel hook has a first element adapted to be affixed to the other end of the cord, and a hook pivotally mounted on the first member.

Abstract: A mounting bracket has a pair of base members hinged together with the base members having separate mounting surfaces to enable affixing them to walls or the like extending at different angles. A mounting projection extends from one base member, preferably normal to the mounting surface thereof, at the pivotal joint. The mounting bracket may be die cast, with an edge of one base member forming a portion of the die for the mounting surface of the other base member. The pivotal axis is preferably displaced so that it is closer to the facing edge of one base member than to the facing edge of the other base member.

Abstract: A swivel hook has a hook member with a frustoconical projection terminating in a cylindrical extension of diameter less than the smaller diameter end of the frustoconical portion. The mounting member for the swivel hook has a frustoconical hole into which the frustoconical projection is fitted. The elements of the swivel hook are adapted to be cast of a metal or molded of a plastic, in such a manner that the bearing surfaces of one of the elements forms a part of the die for the bearing surfaces of the other element. During the casting or molding process, the cylindrical extension is beyond the frustoconical hole, and the elements are moved relative to each other following casting or molding to move the cylindrical extension into alignment with the frustoconical hole.
