Abstract
A truss assembly table having a plurality of sections in succession along its length separated by openings. Each section of the table has several panels in succession separated by openings which extend across the table. Below each opening between the panels, a lead screw drives a carrier which supports a jig stop projecting above the top of the table. Each lead screw is driven by a manually-controlled power-operated device for positioning the corresponding jig stop at a selected position across the table. Power-operated lifts at the openings between sections of the table can be raised to lift a completed truss above the top of the jig stops so that it can be slid off the table laterally.
Claims8
A truss assembly table having a length and a width comprising:
- a plurality of table sections in succession along the length of the table with openings between the sections extending across the width of the table, each of said table sections having a plurality of panels in succession lengthwise of the table separated by openings extending across the width of the table;
- a plurality of lead screws extending across the width of the table along and below the openings between said panels;
- manually-controlled power-operated means for individually rotating the lead screws;
- a plurality of jig stop carriers threadedly coupled individually to said lead screws and movable along said openings between said panels across the width of the table in response to rotation of the corresponding lead screws;
- a plurality of jig stops connected individually to said carriers and projecting above the top of the table above said openings between said panels;
- and a plurality of power-operated lifts at said openings between said table sections, said lifts being movable upward to raise a completed truss above the top of the jig stops.
A truss assembly table comprising:
- a plurality of table panels in succession along the table separated by openings extending across the table;
- a plurality of jig stops located individually at said openings and projecting above the top of the table panels;
- a manually-controlled power-operated positioning means for selectively positioning said jig stops along said openings;
- a plurality of lifts positioned at intervals along the table, each of said lifts being movable betwen a lowered position below the top of the table and a raised position projecting above the top of the jig stops;
- and power-operated means for raising and lowering said lifts.
