A automatic truss jig setting system is disclosed that includes a table including a plurality of segments with a side edge of adjacent segments defining a slot. At least one pin assembly, and optionally a pair of pin assemblies, is movable independently of each other along the slot. Movement apparatus is provided for independently moving the pin assemblies along the slot. Each of the side edges of the segments associated with the slot defines a substantially vertical plane with a zone being defined between the substantially vertical planes of the side edges, and the movement apparatus is located substantially outside of the zone of the slot. The invention may optionally include a system for handling the obstruction of pin assembly movement, and a system for keeping track of the position of the pin assembly when the pin assembly has encountered an obstruction.
A truss jig positioning system for use on a table including at least a pair of adjacent segments with a slot defined by adjacent side edges of the pair of adjacent segments, the table having a support plane on which work pieces are supported, the system comprising:

1. Field of the Invention
The present invention relates to jig systems and more particularly pertains to a new automatic truss jig setting system for setting and resetting jig stops in a highly efficient and effective manner.
2. Description of the Prior Art
The invention will be better understood and objects of the invention will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
FIG. 1 is a schematic top view of a new automatic truss jig setting system according to the present invention employed on a portion of a jig table.
FIG. 2 is a schematic sectional view of the present invention positioned along a slot of the jig table.
With reference now to the drawings, and in particular to FIGS. 1 through 10 thereof, a new automatic truss jig setting system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 8, the truss jig positioning system 10 of the invention may suitably be employed on a table 12 that has and defines a support plane 14 on which work pieces or building elements (such as wood boards or other building materials) are supported in proper position for forming a structure such as a support truss for a roof of a building. The table 12 may comprise a plurality of segments 16 that have upper surfaces 15 that substantially lie in and define the support plane 14 of the table. The upper surface of each of the segments may be substantially planar, and a plane of the segments may be oriented substantially horizontal.
The segments 16 of the table are separated by slots 18, and preferably each of the slots extend substantially parallel to each other on the table. Each of the slots 18 may extend substantially perpendicular to the length of the table, and may extend across, or substantially across, the width of the table. In such a configuration, the slots may be oriented substantially parallel to the rise (or height) dimension of a truss when the truss is rested on the support plane of the table.
