Patent number: 6604897Abstract: Transport racks for shipment of a variety of objects are described. In accordance with one embodiment of the invention, transport racks are configured with vertical and horizontal support members. Cross-braces positioned atop the horizontal support members support partitions of a variety of configurations creating a plurality of longitudinally extending cells forming compartments for secure storage of the cargo. A panel is positioned atop the framework creating a covered storage area with a first and second open end. Netting and lattice gates positioned at the first and second open end secure the cargo, provide high visibility of the rack contents, and maximize ease of loading and unloading of the racks.Type: GrantFiled: September 7, 2001Date of Patent: August 12, 2003Assignee: Variform, Inc.Inventor: Christopher L. Yeomans

Patent number: 6523391Abstract: A vertical impact testing apparatus comprises a rigid frame, an anvil connected to the frame, a dart positioned above the anvil, and a dropped-weight mechanism slidably connected to the frame. The frame is comprised of a vertical column, a base, and a guide rail. The vertical column extends for a sufficient distance to securely support a weight assembly through travel from various heights for testing a specimen. To facilitate downward travel of the dropped-weight mechanism at a proper vertical orientation, a guide block is rigidly attached to the weight assembly and the dropped-weight mechanism is slidably mounted to the guide rail. The dart is stabilized by a braced support arm connected to the frame and a bearing acting cooperatively to ensure impact of the dart with the specimen is in the vertical plane and without tilt. The anvil is a solid structure, fixed in position, which contacts and supports the specimen on a side opposite of the dart as the dart impacts the substrate and forces it downward.Type: GrantFiled: June 8, 2001Date of Patent: February 25, 2003Assignee: Variform Inc.Inventors: Kenneth A. Knox, Ronald Jay Nelson, Terry L. Bellmore, Gregory Lee Carlock

Patent number: 6341464Abstract: A siding panel is provided for attachment to a structure and connection to a similar overlapping siding panel in interlocking relationship. The panel includes a strip for attachment, such as by nailing, to a supporting structure, a receiver formed by outer and inner bends, at least one stretch extending away from the strip and presenting a gap between the outer bend and the stretch, a base and a projection, all extending the length of the panel. The projection is configured to interfit with a receiver of an adjacent panel, with the projection including a flange, a return bend and a cantilever leg. The projection snap fits into the receiver, with the cantilever leg deflecting as the return bend flexes to permit passage of the projection into the receiver.Type: GrantFiled: March 3, 2000Date of Patent: January 29, 2002Assignee: Variform, Inc.Inventors: Eric B. Dickey, Essi Salamatbakhsh, Lewis F. Huebner, Dan Parks

Patent number: 6341463Abstract: A siding panel is provided having a front side and a rear side. The siding panel includes a nail hem for securing the siding panel to a support structure. The nail hem has a proximal member for mounting adjacent to the supports structure and a distal member spaced from the proximal member and the support structure. The distal member terminates in a free end. The siding panel further includes a catch projecting outwardly from the panel. The catch forming an impediment for the free end of the distal member thereby preventing further outward movement of the free end of the distal member.Type: GrantFiled: October 18, 1999Date of Patent: January 29, 2002Assignee: Variform, Inc.Inventors: Eric B. Dickey, L. F. Huebner

Patent number: 5232751Abstract: A method and apparatus (10) is provided for producing vinyl siding (76) having aesthetically pleasing, wood-like striations embedded therein. Apparatus (10) includes processing structure (12) for processing topcoat compound and substrate compound extruders (18, 20) respectively. Acrylic colorant is discharged from feeders (64, 66) into barrel (34) via adapter (72) and thereby mixed with the topcoat compound. The interval of discharge is four seconds every twenty seconds. Adapter (72) utilizes a water jacket to keep colorant cool prior to its introduction into barrel (34) where it experiences a temperature sufficient for melting, usually about 380.degree. F. Due to the interval of discharge and the twenty second period thereof, striations (82) are uniform and continuous in nature so as to simulate wood grain.Type: GrantFiled: June 10, 1991Date of Patent: August 3, 1993Assignee: Variform, Inc.Inventors: Peter D. Cameron, Homer E. Galbraith

Patent number: 5053176Abstract: A method and apparatus (10) is provided for producing vinyl siding (76) having aesthetically pleasing, wood-like striations embedded therein. Apparatus (10) includes processing structure (12) for processing topcoat compound and substrate compound at extruders (18, 20) respectively. Acrylic colorant is discharged from feeders (64, 66) into barrel (34) via adapter (72) and thereby mixed with the topcoat compound. The interval of discharge is four seconds every twenty seconds. Adapter (72) utilizes a water jacket to keep colorant cool prior to its introduction into barrel (34) where it experiences a temperature sufficient for melting, usually about 380.degree. F.

Patent number: 4843793Abstract: A continuous skirt to surround and close the space beneath an elevated building or as a barrier surrounding the insulated foundation of a building is provided with a series of releasably interconnected panels wherein the interlocks therebetween include reverse bends and a corrugation. The interlocks are hidden to provide a rigid connection to resist separation of the panels which connection is aesthetically pleasing when viewed from either side. By providing different colors on each side of each of the panels, the skirting is reversible, thereby reducing dealer inventory.Type: GrantFiled: March 21, 1988Date of Patent: July 4, 1989Assignee: Variform, Inc.Inventor: Randall W. Ayers
