    Abstract: A safety apparatus for protecting an operator of an electrically powered saw from the blade during operation, the saw being of the type including a cutting table through which the blade passes, comprising: an image processing arrangement operable to sense, within a predefined three-dimensional sensing zone, the presence of a glove worn by the operator which has a colour distinguishable by the image sensor from the colour of an object being cut by the blade, the three-dimensional sensing zone being located in a cutting path of the blade; and an electronic controller communicable with the image sensor and operable to control an arresting mechanism to arrest movement of the blade responsive to the coloured glove being detected within the three-dimensional sensing zone.

    Abstract: A push stick for a table saw and a table saw with the push stick are provided. The push stick includes a gripping possibility for a machine operator at its operator-side end. A workpiece engagement notch is formed at the push stick's workpiece-side end. The notch includes a push surface facing in an intended feed direction of the workpiece and a holding-down surface protruding therefrom at the top under a preferably right angle. The push stick includes a detection device which detects whether the push surface and the holding-down surface lie flat against the workpiece. The push stick further includes a signaling device which emits a flat contact signal when the detection device has detected a flat contact of the push surface and the holding-down surface on the workpiece. The signal therefore signals whether the push surface and the holding-down surface lie flat against the workpiece.

    Abstract: A hand-held band saw for cutting a workpiece. The hand-held band saw includes a deck, first and second wheels coupled to the deck for receiving a continuous blade thereabout, a motor coupled to the deck for driving at least one of the first or second wheels, and a handle providing a grip for a user to hold the band saw. The band saw also includes a blade guard having a first portion adjacent the first wheel, a second portion adjacent the second wheel, and a third portion adjoining the first and second portions. A joint couples the first, second, and third portions to the deck for simultaneous movement of the first, second, and third portions with respect to the deck.

    Abstract: Table saws are disclosed. The table saws can include a blade, an arbor, an arbor block, an elevation carriage, and a latch that connects the arbor block and the elevation carriage. The arbor block can have a first position in which the latch connects the arbor block and the elevation carriage, and a second position in which the latch does not connect the arbor block and the elevation carriage. The arbor block can pivot from the first position to the second position upon the occurrence of a retraction force. The table saw can include an actuator to cause the occurrence of the retraction force, and detection electronics to detect contact between the blade and a person. Woodworking machines with detection and reaction systems are also disclosed. A reaction system can include an explosive that causes retraction of a cutting tool.

    Abstract: According to a chain saw braking system, engagement between a front end portion of a belt and a main body by an engagement member is released at the time of application of an impact. When a front end portion is pulled by the spring force of a compression coil spring, an elongate hole for protrusion is engaged with a protrusion to restrict a rear end portion from being moved in the same direction as the front end portion. Thus, it is possible to strongly tighten a drum by the belt to thereby reliably stop the movement of a chain. With this arrangement, the chain can be prevented from being damaged when a chain saw is accidentally dropped onto the ground due to an impact applied thereto.

    Abstract: The safety device for a band saw which includes a vertically displaceable guard which is slidably mounted to a housing of the saw and having a lower end adjacent the table of saw and wherein a pivotable shield is carried by the lower end of the guard. A locking mechanism normally secures the guard in a lowered covering relationship to a band saw blade and must be manually released to permit raising of the guard to allow a workpiece to be moved beneath the shield to be cut by the band saw blade.

    Abstract: A safety guard system for a band saw that comprises a flexible member and a sensor for deactivating the band saw when the flexible member is not deployed correctly. The flexible member has a resting position and a sawing position. In both positions, the flexible member provides a protective barrier between the band saw user and the band saw blade. The flexible member automatically adjusts by flexing to accommodate different sized work pieces.
