  • Patent number: 9217532
    Abstract: A retention system includes a base supporting a wing spar and a post extending through the base from a first side of the base to a second side of the base. The post inserts through an aperture in the spar. A stop is selectively securable to the post over the second side of the base. A locking member engages the post on the first side of the base. The locking member is configured to selectively move the post from an unlocked position to a locked position in which the post is withdrawn toward the first side relative to the unlocked position. A biasing member encircles the post and is positioned between the stop and the second side. When the locking member is in a closed position the biasing member expands to engage the aperture and resist movement of the wing spar. A plurality of cradles may support the wing.

  • Patent number: 6317980
    Abstract: A method of constructing trusses includes providing a laser jigging system that projects the location of the jigging hardware so that an operator can easily, quickly, and precisely position the jigging hardware on the work-surface prior to positioning any truss members on the work-surface is described. More particularly, the system projects puck and other jigging hardware alignment or location guides on the table work-surface. With the alignment guides projected on the table, the pucks and other jigging hardware are located in alignment with the projected guides, and secured to the table. The truss members are located on the table in accordance with the pattern defined by the jigging, and connector plates are then engaged with the truss members.

  • Patent number: 6267365
    Abstract: A locator stop (10) having a body (12) is arranged to be supported on an upper surface of a truss table formed with a plurality of panels (P), so as to extend across a slot (S) between successive panels. The body (12) has a basal surface (22) by which it is supportable on the upper surface of the table. The stop has a lock (14) which projects below the body (12) so as to be at least partly locatable in the slot (S). The lock (14) has dimensions in two mutually perpendicular directions, substantially parallel to the basal surface (22), which respectively are less than the width of the slot (S) and greater than the width of the slot. The lock (14) is adjustable by a manual operation performed above the table, wherein the lock (14) is able to firmly engage at least one of the panels (P) defining the slot (S) and thereby clamp or hold the body (12) on the upper surface at a required position along the slot.

  • Patent number: 6170163
    Abstract: A method of assembling components of an assembly, such as the components of a truss, using a laser imaging system in combination with assembly jigs. The jigs may be slidably mounted on an assembly table wherein the jigs include laser alignment indicia on a top surface of the jigs spaced a predetermined distance from a side surface of the jigs. The method includes projecting an enlarged laser generated outline of at least a portion of the components to be assembled which is spaced laterally from an outline or template of the components in the assembled position a distance equal to the distance between the laser alignment indicia and the side surface of the jigs and spaced vertically a distance equal to the distance between the indicia and the work surface. The jigs are then moved on the work surface to align the laser alignment indicia with the enlarged outline and affixed relative to the work surface.

  • Patent number: 5947460
    Abstract: A table for forming trusses that includes channels that do not unduly deform or bend during truss construction comprises: a support frame; first and second substantially horizontally-disposed elongate panels; a first channel having a generally horizontal floor and opposed side walls extending upwardly therefrom; and a locator stop. Each of the panels has an upper surface, a lower surface, and opposing lateral edge portions, and the panels are positioned so that their respective upper surfaces are substantially coplanar and so that a first of the lateral edge portions of the first panel is in adjacent, non-contacting relationship with a first of the lateral edge portions of the second panel, thereby forming a gap therebetween. One of the side walls of the channel supports the lower surface of the first panel, and the other of the side walls supports the lower surface of the second panel.
