  • Patent number: 8234959
    Abstract: A table saw fence includes a clamping member at both the front and rear of the fence to provide substantial clamping power and accuracy. The fence includes an interior cavity housing a linkage mechanism that engages the front and rear clamps through the actuation of a single handle. Furthermore, the fence includes an opening leading to the interior cavity, thereby permitting the blade, riving knife, blade guard, and any other blade accessories to extend within the interior cavity when the fence is used in a blade cover configuration.

  • Publication number: 20120186410
    Abstract: A power saw that may be flexibly configured to perform multiple cutting functions is provided by attaching a saw assembly to a base assembly with an offset support that provides a clear path in line with the saw blade, thereby providing a miter saw, a table saw or a radial arm saw as desired by the user. In addition, a tilt mechanism is mounted at the top of the offset support to provide an “apparent” tilt axis near the top surface of the turntable, thereby eliminating an axle near the turntable top surface. Materials being cut by the saw assembly are guided by one or more fences. Alternatively, a reversible fence may be used for miter cuts when configured and affixed to the base assembly in a first position, and may be used for table or radial cuts when configured and affixed to the base assembly in a second position.

  • Patent number: 6854372
    Abstract: A miter saw is adapted for performing lengthwise, or rip, operations on a work piece such as wood. A back support arm is positioned off-center such that the work piece can be inserted under the miter saw substantially parallel to the blade. An arcuate aperture in the back support arm ensures that bevel adjustment properly aligns the blade with the blade slot during bevel cuts. An adjustable rail enables the work piece to be positioned in either a normal position, for crosswise cuts, or an orthogonal position, for lengthwise cuts. A toggle switch overrides the on/off switch on the handle, useful when the work piece is fed from behind. Two separate sleeves cover the blade, assuring safety during operation for both lengthwise and crosswise cuts. A tensioning board feed roller holds the work piece in place during lengthwise cutting.

  • Publication number: 20030056630
    Abstract: The present invention provides a miter guide for a table saw that allows the operator to make a miter cut with a slope in a single pass of the workpiece past the cutting blade. The miter guide includes a base within a pivotally attached guide bar that slidably engages the alignment groove in the work table of a table saw. The base is thus pivotably about a vertical axis to one of a selected number of angular orientations with respect to the cutting blade to provide the miter cut desired. A work platform that receives the workpiece to be cut is pivotally attached to the base about a horizontal axis and is thereby adjustable to a number of angular orientations with respect to the base to provide the desired slope to the miter cut.

  • Patent number: 4173161
    Abstract: A trim press for severing cup-shaped articles from a sheet of thermoplastic material in which the articles have been integrally formed as by a vacuum forming operation. A horizontally reciprocable punch is driven to sever articles positioned in a stationary die by a linkage arranged to drive the punch at a relatively slow speed during the severing operation to achieve a smooth shearing separation of the relatively soft thermoplastic material. The sheet is fed into the die in step-by-step movement through vertical sheet guides fixedly mounted in a treadle which is reciprocated with the punch at a proportionate speed. A flexible sheet guide connected between the guides in the treadle and a fixed point on the machine frame flexes to accommodate reciprocation of the treadle while continuously guiding the sheet to the guides on the treadle. Feed fingers mounted on the treadle advance the sheet to the die in step-by-step movement synchronized with the stroke of the punch.
