Abstract: Several preferred embodiments are disclosed for a tool-less blade clamping apparatus for a reciprocating tool of the type which has a reciprocating plunger which has a tool attachment receiving slot for receiving a tool attachment of the type that has a shank portion. The clamping apparatus has an unclamped position and a clamped position. In the unclamped position, a tool attachment can be easily inserted and when it is in its clamped position, the tool attachment is securely retained. The preferred embodiments have at least one spring biasing the apparatus toward the clamped position, a releasable retaining mechanism for holding the apparatus in its unclamped position after being placed in that position. When the blade shank portion is inserted into the slot a predetermined distance, the shoulders of the shank portion release the retaining mechanism to move it to its clamped position.

Abstract: An accessory attachment system for a power tool having an elongated housing with a nose portion, an output shaft to which a cutting blade that oscillates through a small angle is attached, the attachment comprising, an accessory interface removably mounted to the nose portion of the housing and a depth guide attachment rotatably mounted to the accessory interface, the depth guide attachment further comprising a relatively thin body portion having a generally circular first opening with a center axis generally parallel to the output shaft, the body portion fitting on the accessory interface and being rotatable thereon and having a second circular opening transverse to the first opening center axis, a depth guide member adjustably mounted on the body portion and having an offset outer end portion, and a locking member configured to secure the depth guide member in a desired position.

Abstract: A table saw includes a base, a workpiece support structure, and an extension support assembly. The workpiece support structure is supported by the base and defines a workpiece support surface. The extension support assembly includes (i) a guide movable in relation to the base between a first guide position and a second guide position, (ii) an arm assembly movably supported by the guide, and (iii) a cam mechanism movable in relation to the base between a first cam position and a second cam position. Movement of the cam mechanism from the first cam position to the second cam position causes movement of the guide from the first guide position to the second guide position.

Abstract: A corkscrew assembly includes a housing a worm screw assembly, a first gripper, and a second gripper. The housing defines (i) a first opening configured to receive a neck of a bottle, (ii) a second opening, and (iii) an interior space interposed between the first opening and the second opening. The housing includes a sidewall extending from the first opening to the second opening. The sidewall defines a first gripper passage and a second gripper passage. The interior space is interposed between the first gripper passage and the second gripper passage. The worm screw assembly is rotatable in relation to the housing and includes (i) a worm screw member having a pointed first end portion and a second opposite end portion and (ii) a drive member fixed in relation to the second opposite end portion.

Abstract: A detent system that includes a plurality of detent recesses formed in a first component, a detent pin that selectively engages at least one of the detent recesses, a linkage connected to the detent pin, and a detent button that is associated with a second component. There is preferably a slot formed in at least one of the detent button and the detent pin, where each slot slidably receives an end portion of the linkage. The detent system is preferably configured and arranged such that applying a force to the detent button to move the detent button in a first direction causes the linkage to move in a second direction, which is different than the first direction, thereby resulting in disengagement between an engaging portion of the detent pin and a relevant one, or more, of the detent recesses. Such disengagement allows for relative movement between the two components.

Abstract: A collapsible folding stand for use with a portable table saw that is attached to the stand. In a closed position, the stand is generally vertically oriented with the object attached to a top frame. To open the stand a locking mechanism is released which enables a folding mechanism supporting the top frame to unfold in a manner whereby the rear legs having wheels that separate from forward side struts which contact the ground, with the center of gravity of the object being positioned between the wheels and the front ground contact points so that the weight of the object tends to separate the same and bring the top frame into a generally horizontal position. To move the rolling stand to its closed position, the user needs only to lift the handle and the top frame will then move to its generally vertical closed position.
