Patent number: 5308179Abstract: A writing instrument shaped to resemble a flower on a stem with leaves comprised of a hollow tubing housing, a top portion of hollow tubing, an adapter for detachably connecting the top portion to the housing, and a stylus. One portion of the housing is curvilinear, having a plurality of loops shaped to resemble leaves. The top portion is shaped to resemble a flower or bud. The adapter allows the top portion to be detachably connected to either end of the housing. The overall effect is to suggest a flower or bud on a stem with leaves. A second embodiment of the writing instrument uses a base formed of hollow tubing bent into shapes to complement the flower and stem suggested by the housing and top portion. A third embodiment includes a plurality of top portions which are interchangeable and can be detachably connected to the housing using the same adapter.Type: GrantFiled: November 20, 1992Date of Patent: May 3, 1994Assignee: Novelty Creations, Inc.Inventor: Curt E. Whitright

Patent number: 5207524Abstract: An adapter device is provided for varying the length of a ball point pen refill cartridge to enable the cartridge to be used in a variety of ball point pen housings. The adapter consists of a barrel which slips over the distal end of a refill cartridge and is securely connected to the cartridge by a channel formed in the barrel. The barrel comprises detachable sections which are removed as necessary so that the cartridge with the adapter attached barrel sections is substantially equal in length to the exhausted refill cartridge. The channel permits air to flow to the ink cartridge, enabling ink to be flow easily from the cartridge.Type: GrantFiled: October 19, 1989Date of Patent: May 4, 1993Assignee: Arnold Pen CompanyInventor: Remmie L. Arnold III

Patent number: 5171095Abstract: A device applying a two-component composition to a workpiece surface comprises an applicator head (384) to which the two components are supplied separately via tubes (726, 382) arranged one inside the other. The applicator head includes a ball member (392) over the surface of which the components supplied via the tubes can flow and be applied to the workpiece surface, substantially unmixed at the point of application. The applicator head (384) supports a rotary brush assembly (398) which, when its annular operating surface portion is pressed against the workpiece surface, serves both to mix the substantially still separate components on the workpiece surface and to spread the thus formed adhesive composition over the workpiece surface.Type: GrantFiled: March 19, 1991Date of Patent: December 15, 1992Assignee: British United Shoe Machine Ltd.Inventors: John Davies, Raymond Hanson, Frank C.
