The drain tube includes a threaded bore that is configured to receive a correspondingly-threaded drain plug therein. A method of producing a molded floor covering having an integrally formed, threaded drain tube includes providing a mold having a contour of a vehicle floor with an outwardly projecting threaded member. A layer of thermoplastic polymer is vacuum formed over the mold and around the threaded member such that the layer follows the contours of the mold and threaded member to form an elongate tube extending therefrom.Type: GrantFiled: June 25, 1999Date of Patent: March 26, 2002Assignee: Collins & Aikman Products CoInventors: William Duncan McIntosh, Dayne Stuart Haight

Publication number: 20010032851Abstract: A preferred storage system includes a container, a closure lid, and a compression link. Preferably, the container includes an outer wall, which defines an interior, and a first open end. The closure lid is configured to be inserted within the open end of the container, and is adapted to engage in a sealing relationship with the outer wall of the container. Preferably, the compression link includes a container engagement surface and a closure lid engagement surface. The compression link is configured to engage between the closure lid and the outer wall of the container to retain the closure lid in sealing engagement with the container. The container engagement surface and the closure lid engagement surface are configured to extend outwardly from each other, with the container engagement surface being adapted to engage the outer wall of the container and the closure lid engagement surface being adapted to engage the closure lid. Methods also are provided.Type: ApplicationFiled: December 22, 2000Publication date: October 25, 2001Inventors: Charles W. Pennington, George C. Carver

Patent number: 6290279Abstract: Floor drains are provided that can be inserted through floor coverings and through multiple floor panels of a vehicle body. An elongate hollow body terminates at an open distal end and at an open proximate end. A flange extends circumferentially around the open proximate end. One or more resilient members extend circumferentially around, and outwardly from, the body in adjacent spaced-apart relationship with the flange. The resilient members are configured to secure the floor drain within a vehicle floor panel such that the flange compressively engages the floor panel.Type: GrantFiled: June 25, 1999Date of Patent: September 18, 2001Assignee: Collins & Aikman Product Corp.Inventors: Dayne Stuart Haight, William Duncan McIntosh

Patent number: 6189718Abstract: A fluidtight seal for a container is formed by abutting a metal ring with a step machined in a convexo-concave container closure device and inserting this assembly into an open end of the container. Under compressive force, the closure device deforms causing the metal ring to pivot about the step on the closure device and interact with symmetrically tapered inner walls of the container to form a fluidtight seal between the container and the closure device. The compressive force is then withdrawn without affecting the fluidtight characteristic of the seal. A destructive force against the container closure device is necessary to destroy the fluidtight seal.Type: GrantFiled: March 31, 1999Date of Patent: February 20, 2001Assignee: The United States of America as represented by the Department of EnergyInventor: Edward F. Morrison

Patent number: 6170690Abstract: Provided by the invention is an air-tightly sealable bell jar container comprising a base plate and a bell jar covering mountable on the base plate. An air-tight sealing mechanism is obtained by forming a laterally and downwardly opening annular groove in the base plate to support an O-ring gasket of rubber and providing, below the base plate, a presser plate which presses up the O-ring gasket against the base plate by a means of cams or screw means in such a fashion that the O-ring gasket is elastically deformed and laterally bulged out to be brought into air-tight contacting with the inner wall of the bell jar covering surrounding the base plate.Type: GrantFiled: May 14, 1999Date of Patent: January 9, 2001Assignees: Shin-Etsu Polymer Co., Ltd., Shin-Etsu Handotai Co., Ltd.Inventor: Masato Hosoi

Patent number: 6076797Abstract: An apparatus for blocking a hole, especially for blocking a passageway within a mold. The apparatus includes one or more tapered members received within recesses of an expandable sleeve. As the one or more tapered members are drawn within the sleeve by a fastener, the outer diameter of the sleeve expands so as to substantially block the hole. The apparatus also includes a surface with threads that are the opposite hand of the threads of the fastener. This second set of opposite hand threads permit holding and placing the apparatus within a location of the hole, and also for reacting the torque applied by a second tool used to tighten the fastener.Type: GrantFiled: October 1, 1998Date of Patent: June 20, 2000Inventor: Kurt Schnautz

Patent number: 5884668Abstract: The invention is directed to a plumbing tool for temporarily plugging a pipe which normally contains fluid or gas under pressure. The plumbing tool includes an elongate threaded rod having proximal and distal ends. A hollow elongate sleeve is disposed around the threaded rod. Similarly, a cylindrical gasket is disposed around the rod between the hollow sleeve and a gasket stop located at the distal end of the elongate rod. The plumbing tool further includes an arcuate handle extending proximally from the proximal end of the elongate threaded rod. The arcuate handle is configured to include a radius sufficiently great to permit valves to be telescopically communicated along the entire length of the arcuate handle and along the length of the hollow elongate sleeve.Type: GrantFiled: September 25, 1997Date of Patent: March 23, 1999Inventor: Brent H. Larkin

Patent number: 5881420Abstract: A tool for clamping against the interior of a chimney flue having a scissors jack mechanism for adjustably clamping into various size chimneys. A seal plate for sliding over the shaft of the clamping device and for tightly sealing against the interior chimney flue walls. A cleaning brush mechanism affixed to the end of a tubular member, sized to slide over the clamping shaft for cleaning the interior of a chimney.Type: GrantFiled: November 19, 1996Date of Patent: March 16, 1999Inventor: Mark Bruckelmyer

Patent number: 5740935Abstract: A bung hole plug formed of resilient synthetic material interfitted between a front and back plate. A threaded post is attached to the back plate, and used, in conjunction with a lock washer and nut, to draw the front and back plates together, thereby squashing the resilient plug against the side walls of the bung hole to maintain a fluid tight seal.Type: GrantFiled: April 9, 1996Date of Patent: April 21, 1998Assignee: Idaho Bung Co., Inc.Inventor: Laurent A.
