Work Holder For Prefabricated Roof Truss Or Wall Frame Patents (Class 269/910)
  • Patent number: 4627564
    Abstract: An apparatus for forming a truss assembly is discussed which is particularly configured for versatility and efficiency of operation. The apparatus includes a frame which supports a pair of laterally spaced first and second support rails which receive the chords and the webs of the truss assembly being formed. A pair of pressure clamps are provided which are selectively positionable longitudinally of the apparatus frame for applying clamping pressure to nail plate connector portions of the truss assembly for joining the truss webs and chords. Notably, the apparatus includes an arrangement whereby the support rails of the apparatus can be laterally relatively moved for forming truss assemblies of varying finished heights, with the arrangement including a plurality of slide cylinder assemblies which function in the nature of double-acting fluid rams for applying a clamping pressure to this truss assembly laterally of the apparatus frame as the pressure clamps are operated for joining the elements of the truss.

  • Patent number: 4575059
    Abstract: The invention relates to a method and a jig for constructing a carcase-type article of furniture. A panel which is to form a part (e.g. a door) of the finished article, is placed down on a horizontal surface. A jig is assembled around the panel using the panel as a template, the jig incorporating abutment blocks to contact the edges of the panel and locating blocks in predetermined positions relative to the abutment blocks to define the positions of the carcase walls and to locate the walls in position while being secured to one another. The carcase walls are cut to the desired size, and placed edge down within the locating blocks of the jig. Securing the walls to one another now forms a carcase the walls of which are correctly aligned with the edges of the panel.

  • Patent number: 4567821
    Abstract: Apparatus for use in assembling wooden trusses and girders by holding wooden members in proper location and orientation while fastener plates are pressed into place. A frame supports an adjustable grid for supporting a clamp table at the location of each joint between wooden members, and a tower, moveable along the length of the frame, carries an articulated boom supporting an upper clamp assembly which is matable with each clamp table to press fastener plates into opposite sides of the wooden members to join them together. The apparatus is extendable and includes a wheeled undercarriage which is removeable.

  • Patent number: 4541618
    Abstract: A jig for manufacturing wooden fencing or shed panels is adaptable to a range of sizes. A horizontal rectangular main frame (4) provides location for all the peripheral battens of a maximum size panel and for some of the peripheral battens of lesser panels. Spanning the frame is an array of parallel beams (12) which can be adjusted transversely to their longitudinal direction. These beams carry locating elements (14) which can be adjusted longitudinally of their respective beams. Intermediate panel battens, and peripheral ones for reduced size panels, can be laid along the beams or transversely to them, in each case being held laterally by the locating elements, and at a height compatible with that of any batten resting on the main frame. Corner and T-junctions of battens can be made at any locating element, with access for nailing them together, and the main frame also provides nailing access for such junctions.

  • Patent number: 4453705
    Abstract: A trailer bed or chassis including side rail extensions and center rail support posts serves to mount a wooden truss fabricating jig including laterally adjustable center rail sections and associated transverse arms for the support of truss lumber. An arrangement of permanent stops and swivel stops on the jig together with a truss peak locator and splice locator enable the setting up on the job site of a calibrated jig prior to placing the truss lumber thereon, resulting in a great savings of time in truss fabrication. Trusses are produced with precision and uniformity having improved quality and a wider range of truss sizes can be accommodated with the apparatus because of its versatility.

  • Patent number: 4383680
    Abstract: A jig for assembling table tops such as picnic table tops, which have a plurality of similar elongated rectangular top members secured together in aligned fashion on transverse bottom members. The jig comprises a frame to which are secured transverse member holders having bottom and side surfaces to receive and secure in parallel position at predetermined spaced locations the transverse members in such a way that the upper surfaces of the transverse members in position in the transverse member holders lie in the same plane. The jig also comprises alignment means secured to the frame to align one end of the top members when in assembly position on the transverse members in the transverse member holders. An alignment means is rigidly secured to the frame at a position which will properly orient a top member with respect to the transverse member by abutment of one of the top member's side surfaces against this alignment means.

  • Patent number: 4322064
    Abstract: A plurality of serially-disposed and pivotally-connected elements comprise the object-spacing tool of the present invention. The tool can be compactly folded to a size approximately the length of one element or expanded to a length approximately the total length of all the elements. Each element has two members projecting therefrom; typically, each projecting member is at or near an end of the element. Each projecting member is constructed to cooperate with a projecting member from an adjacent element for clamping an object therebetween. These cooperating pairs of projecting elements are spaced a fixed distance from each other, thereby spacing the objects clamped therebetween a predetermined distance from each other.
