  • Publication number: 20220372763
    Abstract: A gutter cover system has a reverse-curve cover and clips, fastened to fascia, that secure the back edge of the cover. The front of the cover has an S shape with a convex upper part and a concave lower part. The lower part clips inside the upper front edge of the gutter. The cover is corrugated with fore-aft extending ridges and grooves. The corrugations create small triangular openings for water to enter the gutter while preventing small leaves and evergreen needles from entering the gutter.

  • Patent number: 10526779
    Abstract: A metal building system has multiple spaced building sections connected by inner and outer batten panels. Each building section has two spaced frame elements connected by inner and outer skin panels. The frame elements have two walls and a roof. The batten and skin panels have a metal layer that faces away from the frame elements and an insulation layer that faces the frame elements. The skin panels are seamed to the frame element and the batten panels are seamed to the skin panels such that there is no metal to metal contact between the frame elements, the skin panels and the batten panels. Each building section can be assembled at ground level, rotated to a final upright position and anchored.

  • Publication number: 20180305918
    Abstract: An enclosed cross-section building frame member has two elongated, sheet metal elements that are connected together by diametrically opposed, double overlapped seams. The elements are generally L shaped and can be compactly stacked for shipping to a construction site. The seams are cross serrated to prevent longitudinal slippage. A portable seaming apparatus has an entry guide tube for assembly of the elements prior to seaming. The apparatus is adjustable for making different sizes of frame members.

  • Patent number: 9109352
    Abstract: A metal building system has frame elements covered and connected together by cladding panels. The frame elements have tapered, roll formed wall and roof beams that connect at the wide ends. The cladding panels have large corrugations across most of each panel for rigidity and small corrugations along the edges to allow for roll forming of flanges and for rain drainage. Purlins fastened to the inside of the wall and roof beams connect the frame elements and support insulation panels on the inside of the building system.

  • Publication number: 20050193639
    Abstract: An adjustable hood system for rain gutters has a flat roof section, a hood section rotably connected to the roof section, and fastening members that rotably connect to the hood section. The fastening members mount on the front lip of a rain gutter while the roof section integrates with the roof. Relative rotation of the roof section, hood section and fastening members permits the hood system to be mounted on roofs with any slope and pitched rain gutters at any level relative to the roof.

  • Patent number: 6931903
    Abstract: Apparatus for roll forming shaped members from sheet material has a primary powered section that roll forms along a primary pass line and a secondary powered section. The secondary powered section is coupled to and powered by the primary powered section, and roll forms along a secondary pass line that is separate from the primary pass line. The secondary powered section is coupled to the primary powered section by a transmission that allows adjustment of the secondary pass line in translation in two directions and in rotation in two directions. The method of roll forming includes forming shaped members in sections with the apparatus.

  • Patent number: 6854313
    Abstract: Tube bending/crimping apparatus has a frame, a toggle assembly and a carriage assembly. The toggle assembly has overlapping male dies with tapering working tips that form a self-centering wedge. The carriage assembly has a shaft with a pinion that engages a rack on the frame to move the carriage assembly. A handle on the shaft is linked to the shaft by a cam clutch and a plunger, so that when the plunger is engaged, pushing the handle moves the carriage assembly forward. When the plunger is disengaged, the carriage assembly is easily moved back to the starting position. Mechanical stops for the handle assure consistent advancement. A receiving element on the carriage assembly has grooves for several sizes and orientations of tube.

  • Publication number: 20040255522
    Abstract: A panel includes a sheet of material and an array of spaced projections on the sheet. The projections are cut and folded from the sheet, cast or molded. The projections create turbulence in drainage across the sheet, increasing drag and reducing flow velocity. The panel is mounted in a roof valley, along roof eaves above the rain gutters or anywhere that excess drainage flow velocity can create a problem. The panel is also an improved snow and ice guard for a roof.

  • Publication number: 20040000098
    Abstract: Fastening device, a clip-in shield, and a shielded gutter system are disclosed. The fastening device is configured to attach a gutter to a mounting structure, rigidly position and support the gutter, and rigidly position and support the shield over the gutter. Each fastening device maintains both the gutter and the shield in rigid positions relative to one another and facilitates both front and rear drainage from the shield. A plurality of the fastening devices at spaced intervals along the gutter and shield are used to provide the shielded gutter system. The first embodiment of the fastening device has the intermediate body portion extending substantially perpendicular from the front rearwardly to the base portion at the rear and the second embodiment has the intermediate body portion extending rearwardly and down at an angle to the back portion to provide for increased support of the gutter front wall.

  • Patent number: 6119498
    Abstract: A node roller combination method and apparatus has a node roller and a backing roller between which sheet material is passed. The node roller has a series of ring shaped circumferential nodes at spaced intervals across the material. The nodes press the sheet material into the backing roller to form a series of small radius small angle bends between flat segments and repetitions of succeeding stages of node and backing rollers forming bends between previous bends that provide a curved shape that gives the appearance of a large radius bend without the tendency to spring back to an original shape.

  • Patent number: 5991993
    Abstract: Portable apparatus for connecting panels with an interlocking seam is disclosed. The apparatus includes three rollers disposed in a triangular configuration. Two guide rollers support connecting flange portions of the panels and a forming or hem roller turns a terminal section of one connecting flange portion back to form the seam. A larger hem roller reduces forming stresses and improves quality. Apparatus also connects panels by seaming a cap over adjacent connecting flange portions. The apparatus may be manually driven or motor driven.

  • Patent number: 5860213
    Abstract: A frame assembly and method of making includes forming a series of pairs of aligned, inwardly extending markings in the form of detents or holes at selected positions in opposed track side walls preferably before forming the sheet metal into the U-shaped profile, providing aligned holes at selected positions in end portions of each stud, inserting the end portion of the stud inside a track so each marking is in an adjacent hole of the aligned pairs of holes and markings, and punching through the markings into each hole to form a hollow stem that draws the end of the stud into the track and the end of the stud against the top surface of the base wall of the track, brings the centers of the holes and markings in alignment to positively fasten each stud to each track. A further step may include flaring or flattening the open end of the stem to a selected angle to form a rivet head.
