  • Patent number: 6708593
    Abstract: A folding, straight-line, workpiece guide for a saw having a base, a saw blade extending vertically through the base, and a feed path relative to the saw blade. The workpiece guide comprises an elongated table which can be collapsed into a folded configuration or set up and locked into a working configuration. A carriage is constructed and arranged to support multiple elongated workpieces and to slide along the foldable table. The foldable table has multiple chassis sections pivotally connected to one another, adjustable legs, connectors for connecting the table to the base of the saw parallel to the feed path of the saw, and a guide track for guiding the carriage along the table when the table is in the working configuration.

  • Publication number: 20030000358
    Abstract: A adjustable shuttle stop apparatus for use in controlling feeding of material to a machining operation on a machine tool, such as a band saw. The apparatus comprises a feed conveyor, a band saw adjacent to the feed conveyor, a shuttle vise movably disposed on the feed conveyor, and an adjustable stop on the feed conveyor for adjusting a distance between the stop and the shuttle vise and for stopping the shuttle vise at the cutting position. The adjustable stop compensates for undesired movement of the shuttle vise caused by clamping the workpiece such that the distance between the stop and the shuttle vise remains substantially constant. This allows for a consistent cut length of the workpiece on subsequent cutting cycles. Different embodiments of the adjustable stop are disclosed along with a method of use of the apparatus.
