  • Patent number: 9403284
    Abstract: A rip fence mechanism for being slidably connected to a worktable of a sawing machine includes parallel and spacedly arranged first and second rails, a fence plate pivotally connected between the first rail and the second rail in a way that the fence plate is pivotable between a vertical posture and a horizontal posture, and a support plate pivotally connected with the fence plate in a way that the support plate is pivotable between a first position where the support plate is abutted with the fence plate and a second position where the support plate is vertical to the fence plate. As a result, the lateral side of a to-be-cut workpiece can be directly stopped at the fence plate at the vertical posture and a bottom of the workpiece can be supported by the support plate at the second position during cutting.

  • Patent number: 9377079
    Abstract: A dynamic platform with extending struts has fastened thereto a bi-directional torsional power unit to selectively deliver force opposing either extension or flexion, and to provide assistance in a respective opposite direction. The power unit is threadably mounted on a hinge pin (spline) centrally located on the platform, and is latched to a catch assembly radially located thereto, the hinge pin of the platform communicating with one end of a torsion spring of the power unit and the catch assembly communicating with another end of the torsion spring, to selectively deliver the extension/flexion force. The power unit can be detached, with simple manual operation of the catch assembly, without tools, flipped over and reattached to the same platform attachment points to switch (reverse) extension torque to flexion torque and vice versa.

  • Patent number: 9302371
    Abstract: A length adjustable worktable includes a main table, a side extension, a guide unit, and an actuating device. The guide unit is engaged with the side extension for guiding the side extension to slide toward or away from the main table. The actuating device includes an operating member, a driving unit, and a positioning member. By manipulating the operating member, the driving unit and the positioning member are driven, such that the side extension is able to slide toward or away from the main table along the guiding unit, thereby allowing the length of the worktable to be adjusted.

    Abstract: Improved arrow shaft rotary cutting systems for home arrow makers. An arrow shaft rotary cutting system comprises a safety box configured to mount a rotary cutting tool and a means for holding each arrow shaft at a predetermined length while being cut by the blade of the rotary cutting tool. Various embodiments of novel safety boxes and novel end pieces are provided. Some embodiments use arrow shafts as system shafts that separate the safety box and the end piece. The cutting length is set to a predetermined length. Arrow shafts are cut to the predetermined length within the safety box. Other heavier duty embodiments, which include a clear safety shield, use angle iron to hold the end piece.

  • Patent number: 9221188
    Abstract: A fence device includes a coordinate system for providing accurate positioning of a workpiece along two perpendicular axes. Precise repeatable positioning of the workpiece relative to a given reference point is achieved. Two or more separate calipers are used for the positioning. The device includes parallel channels along two opposing edges of a table top. Channel guides along edges of a fence engage the channels for movement of the fence toward and away from a cutter bit or other material removing tool. A first caliper determines the distance that a workpiece may be moved when engaging the cutter bit. The location of a workpiece along the fence is determined using a second caliper perpendicular to the first caliper. A slide plate is secured at right angles to the fence and uses the second caliper to accurately position the distance of the fence with relation to the tool.

    Abstract: This invention is a work carriage used with a cutting tool's table surface to make straight-line cuts. The device responds to the need for cutting a wide range of angles and positions on workpieces of different sizes and shapes more accurately, consistently, and safely. The invention consists of a main support which rides on a slide attached to the table surface's guide slot using a wedging action to fill the width of the guide slot. Clamps hold the workpiece to the main support along a t-shaped channel. Once set up, the main support moves precisely along the slide parallel to the guide slot and cutting plane. The main support also has threaded holes to attach workpiece stops and a fence, as needed, for making consistent cuts. A secondary support is used to provide the necessary support with a larger workpiece that has a center of mass beyond the main support.
