  • Patent number: 7178438
    Abstract: The present invention relates to a power miter saw with a quick actuating mechanism for a movable guard. The mechanism comprises a mounting arm, a fixed guard, a drive means and a circular saw blade. A movable guard is pivotally connected to the fixed guard. The movable guard is pivotally connected to the front end of the actuating link by a second guiding member. The rear end of the actuating link is movably connected to the mounting arm. A first guiding member is disposed on the rear end of the actuating link and the mounting arm has a first arcuate slide slot with which the first guiding member engages. When the fixed guard moves together with the saw unit downwardly, the actuating link pivotally engages the first slide slot and actuates the movable guard rapidly to open. The movable guard of the present invention can be easily manufactured and conveniently assembled or adjusted so as to reduce the cost.

  • Patent number: 6925919
    Abstract: A table saw has a height and inclination adjustable saw blade which is mounted on and rotatable with a blade shaft that is driven by a motor. A support seat is movable relative to a mounting frame, and supports the blade shaft. A shaving collecting member is disposed in the vicinity of the saw blade to collect wood shavings. A casing is secured to the support seat, and is communicated with the shaving collecting member. An impeller is disposed rotatably in the casing, and is mounted on a driven shaft that is coupled to the blade shaft so as to permit rotation of the impeller when the motor is in operation, thereby drawing wood shavings from the shaving collecting member to the casing and out of a discharge port in the casing.

  • Patent number: 6925916
    Abstract: A press for forming a workpiece with a tooling set includes an actuator assembly carrying a movable half or punch of the tooling set and having a two phase operation. In the first phase the actuator provides relatively low force in moving the punch to an intermediate position in close proximity to the workpiece. A sensor detects the position of the punch, and when the punch reaches the intermediate position provides a continue signal. The second phase of actuator operation is conditioned on occurrence of the continue signal, and uses normal high force to press the movable tooling half against the workpiece to complete the operation. The low force first phase allows obstructions of any kind to stop movement of the punch during the first phase before high force applied to the actuator may cause damage or injury to the obstruction. In a preferred embodiment the actuator assembly has hydraulic operation.

  • Patent number: 6907809
    Abstract: A saw blade positioning device has two drive mechanisms and two guidance devices, which are preferably oriented at right angles in respect to each other. If a first guidance device is oriented in the radial direction of the circular saw blade by the linear guides, and the other guidance device in the circumferential direction, a desired advancement curve of the engagement member, independently of the saw blade diameter, is achieved respectively by means of the same control, or respectively the same control pulses, and of the drive mechanisms, in every radial position of the first guidance device. A mechanically robust basic structure results in addition, which makes a precise positioning possible.

  • Patent number: 6826993
    Abstract: An apparatus for slitting a running paperboard web includes a thin high speed rotary slitting blade that is plunged through the moving web and into a slot between a pair of anvil surfaces supporting the web on the opposite side. Because the slitting blade and the anvil surfaces are vertically separated and pre-positioned before order change, an adjustment apparatus is provided to spread the anvil surfaces apart to provide an open gap with a large target for blade edge when it is plunged through the web and into the slot. The anvil surfaces are then closed to bring the edges of the surfaces against the opposite faces of the blade for running operation. Preferably, the anvil surfaces are mounted on brackets hinged together below the surfaces to move the edges of the surfaces defining the slot between the opened and closed positions in the manner of a clam shell.
