Patent number: 4356217Abstract: Production of a longitudinally striated coating on a strip article by advancing the article past an open side of an otherwise-enclosed trench so that the article surface to be coated closes the open trench side, while delivering concurrent laminar flows of two different liquid coating materials to the trench at least at one locality spaced from the trench open side, to keep the trench completely filled and to deposit a layer of coating material on the moving article surface. Liquid circulation in the trench caused by the motion of the article surface so distributes the two coating materials along the trench that the applied coating layer is constituted of alternating longitudinal striations of the two materials.Type: GrantFiled: January 21, 1981Date of Patent: October 26, 1982Assignee: Alcan Aluminum CorporationInventors: Carl A. Wollam, J. Lynn Gailey, Alexander A. Chalmers

Patent number: 4344990Abstract: In the coating of a strip article by continuously advancing the article lengthwise past a dam while applying liquid coating material to a major surface of the article ahead of the dam, and advancing the article surface past a facing wall of extended length immediately beyond the dam, the article is restrained against movement away from the wall by an endless surface moving in the same direction and at the same rate as the article. The liquid coating material, in contact with the article major surface ahead of the dam, is fully confined within a reservoir or trench to which the coating material is supplied under positive pressure to maintain the reservoir or trench continuously entirely filled therewith.Type: GrantFiled: January 21, 1981Date of Patent: August 17, 1982Assignee: Alcan Aluminum CorporationInventors: Carl A. Wollam, J. Lynn Gailey, Alexander A. Chalmers

Patent number: 4292781Abstract: A siding panel system for use on an exterior building wall or the like, including an overlapping interlocked array of horizontal siding panels 12, wherein the siding panels are secured to the wall by modular insulating and mounting units each comprising an insulating panel 10 and means such as a plurality of horizontal retainer strips 11 disposed in vertically spaced relation on the outer surface thereof for correctly positioning and facilitatingly mounting successive courses of the siding panels in the array. The retainer strips 11 have horizontally extending inward projections 130 received in recesses 28 defined by the insulating panels 10 for positioning the retainer strips properly to engage the successive siding panel courses. The modular units are attached to a wall by fasteners such as nails 52.Type: GrantFiled: August 8, 1979Date of Patent: October 6, 1981Assignee: Alcan Aluminum CorporationInventors: Alexander A. Chalmers, J. Lynn Gailey

Patent number: 4288958Abstract: An array of overlapped, interlocking horizontal siding panels secured to a wall by parallel vertical stringers having vertically spaced resilient clips for holding the top margins of the panels, wherein the panel top margins and stringer clips cooperatively provide a double locking arrangement such that as a panel is mounted on the stringers, it is moved into a first position in which its top margin engages clips of the stringers and then is moved upwardly into a second position in which it simultaneously further engages the clips and interlocks with the next lower panel in the array. To this end, the top margin of each panel has a locking projection above the conventional lip provided for interlocking with the bottom margin of the adjacent higher panel, and each clip has two vertically spaced locking surfaces for successively engaging this locking projection as the panel top margin is pushed upwardly under the clip.Type: GrantFiled: June 18, 1979Date of Patent: September 15, 1981Assignee: Alcan Aluminum CorporationInventors: Alexander A. Chalmers, J. Lynn Gailey

Patent number: 4228629Abstract: A vertical siding system for an exterior building wall, including vertically oriented panels mounted in flush side-by-side array on supporting structure of the wall and vertically oriented cover members covering the joints between adjacent panels and interlocked with the panels. The cover members have locking flanges along their side edges for insertion in locking grooves formed in side portions of the panels, and are resiliently deformable so that they can be snap-fitted onto the panels after the panels are mounted on the wall. The panels and cover members may be designed to cooperatively simulate the appearance of conventional board-and-batten wooden siding.Type: GrantFiled: May 26, 1978Date of Patent: October 21, 1980Assignee: Alcan Aluminum CorporationInventors: Alexander A. Chalmers, J. Lynn Gailey, James A. Englund, Stephen Popek

Patent number: 4195455Abstract: A soffit system includes a plurality of panels of individually adjustable length, in a side-by-side nested array supported on at least two spaced-apart stringer members. Each adjustable panel has at least two similar components, an end portion of one being inserted in an end portion of the other so that the two components overlap. Each component has a horizontal web and two parallel side flanges with conformingly curved profiles opening in the same direction, i.e. one flange being externally concave and the opposite externally convex. The side flanges of the overlapped components snap fit together to interlock their overlapping end portions, thus providing the adjustable-length feature.Type: GrantFiled: May 17, 1978Date of Patent: April 1, 1980Assignee: Alcan Aluminum CorporationInventors: Alexander A. Chalmers, J. Lynn Gailey

Patent number: 4193238Abstract: A snap-on cover for window casings including elongated metal or like resiliently deformable case molding members mountable on brackets secured at spaced locations along a window casing. The case molding members snap onto the brackets; each bracket has a base, a pair of spaced, aligned seats projecting outwardly therefrom for engagement by the edges of a molding member, and a leg also projecting outwardly from the base for retaining the molding member against inward displacement. A screw extending inwardly through an elongated opening in the base and surrounded by a helical spring under compression between the screw head and the base secures the bracket to the subjacent casing or other structure in a manner enabling self-aligning positional adjustment of the bracket in several directions when a molding member is mounted thereon. The case molding members may be provided as overlapping sections, to accommodate a range of window dimensions.Type: GrantFiled: May 26, 1978Date of Patent: March 18, 1980Assignee: Alcan Aluminum CorporationInventors: Alexander A. Chalmers, J. Lynn Gailey, Carl A. Wollam

Patent number: 4130974Abstract: A horizontally elongated sheet metal siding panel simulating the appearance of a row of shake-type wooden shingles is produced by forming, in the panel, alternating raised and depressed shingle-simulating portions having surfaces lying in spaced parallel planes and separated by narrow portions that taper upwardly as viewed in projection in the surface planes of the shingle-simulating portions.Type: GrantFiled: February 16, 1977Date of Patent: December 26, 1978Assignee: Alcan Aluminum CorporationInventors: Alexander A. Chalmers, J. Lynn Gailey, Carl A. Wollam
