Abstract: A dust or chip collection and diversion system is provided for a device having a cutting tool for performing a working operation on a workpiece. The position and orientation of the dust-receiving or dust-collecting opening remains constant with respect to the cutting tool regardless of the position or configuration of the device, the device having a movable blade or other cutting tool, thus greatly enhancing the dust collection effectiveness in any of a number of operational configurations. Such position and orientation of the dust-receiving opening is also independent of the movement or position of any adjustable or movable guard or workpiece-supporting fence.

The cam portion is adapted to engage an item to be clamped on the base.

Abstract: A workpiece guide includes a fence receiving member having first and second sides, a first mounting member disposed adjacent the first side, and a second mounting member disposed adjacent the second side. A first linking member is connected to the first mounting member, and a second linking member is connected to the second mounting member. A link receiving member is connected to both linking members and may be manipulated to selectively simultaneously bias the first and second mounting members toward or away from the link receiving member.

Abstract: A workpiece positioning device for precisely positioning a workpiece relative to a power tool or other device. The device includes a stationary base, an elongated locator member carried by the base for limited slideable movement right and left thereof. The locator member having a set of spaced-apart circumferential slots therein. An elongated scale made fast to the base and disposed adjacent to the locator member has a set of axially aligned spaced-apart through-apertures therein for positioning of the scale relative to said locator member. A movable stop having a surface thereon for abutting against a workpiece is disposed adjacent to the locator member for limited slideable movement right and left thereof. The movable stop being incrementally positionable relative to the locator member. The locator member being incrementally positionable relative to the scale. Whereby a workpiece abutting the movable stop will be exactly located in the precise position selected therefor.

Abstract: The present invention provides a workpiece positioning device for precisely positioning a workpiece in a predetermined position relative to a power tool or other device quickly and efficiently. This device provides a simple and dependable apparatus for quickly and easily positioning a workpiece, and adjusting the position of the workpiece in small increments. The workpiece positioning device includes a fence member, having a surface thereon for abutting against a workpiece, the fence being disposed adjacent to a locator member for limited slideable movement right and left thereof, whereby a workpiece abutting the fence will be exactly located in the precise position selected.

Abstract: A table saw has a frame, an upper surface and an auxiliary table and having a dual sliding rail mechanism so that the auxiliary table moves between a first position adjacent the upper surface and a second position separated from the upper surface. The dual sliding rail mechanism includes support brackets that are secured to the front and rear edge surfaces of the table saw, mounting brackets that are connected to the front and rear edge surfaces of the auxiliary table and a front and rear rail having channels that slide over the support brackets and which are secured to the auxiliary table by the mounting brackets. A locking mechanism secures the auxiliary table in any position between the first and second position.

Abstract: An apparatus for decurling food material, such as slices severed from a food material supply, while the slices are being moved toward a transfer member includes a constriction positioned in close proximity to the slicing station and in general alignment therewith. The constriction is defined by opposing upper and lower surfaces; the upper surface is a stationary surface while the lower surface is a moving surface. The lower moving surface utilizes a plurality of flexible bands rotating around at least one roller, which are disposed proximate to the food material supply. The flexible bands are driven around a guide member having an arcuate profile that matches the curvature movement that the food material supply takes. The bands which form the lower moving surface are driven at a speed equal to or greater than the speed at which the slicer operates.

Abstract: A machining tool includes a table, an adjustable fence disposed on the table, a fixing device coupled to the fence and a lever operable by an operator. The fixing device can be operated to fix the fence in position or to permit the movement of the fence relative to the table by the operation of the lever. As a result, a tool is not needed to change the position of the fence relative to the table.

Abstract: An adjustable rip fence for a machine tool has a fence which is movable with respect to the cutting tool due to a rack and pinion. The rail assembly supporting the fence include a pair of stationary rails which are secure to the machine tool. A movable rail telescopically engages each stationary rail and the movement of each rail is accomplished by the rotation of a pair of pinion gears each of which engages a respective rack on the movable rails. The simultaneous rotation of the pinion gears is the result of both pinion gears being secured to a common pinion shaft which is rotatably secured to the machine tool. The telescoping nature of the rails allows for adjustment of the fence beyond the working surface of the machine tool.

Abstract: A novel precise, multiple indexing jig used in conjunction with power tools, especially a power saw, is disclosed. The jig includes a longitudinal indexing rod that precisely locates and supports by pivotal articulation, a plurality of swing arms. The swing arms can be rotated onto the table and used as stops to assist in positioning a work piece on the device that is to be worked at a specific location, such as the cut length for a saw. When they would be in the way of a work piece, they can be rotated away from the table. The indexing rod is positioned parallel to a guide fence that also locates the work piece. A series of location supports are also located on the indexing rod and further support the swing arms. An alternative embodiment enables the guide fence to also index with the swing arms, thereby increasing the structural stability of the swing arms when they are positioned as stops.

Abstract: Disclosed is an apparatus for precisely, easily and automatically setting and resetting stops on a cutting table. In particular, a hand manipulable pointer slideable along a scale may be moved a desired and equal distance to that desired of the stops, and the stops will automatically move that same distance and direction. The system is accomplished by operatively coupling the stops and the pointer system to a linear actuator. Also disclosed is an electromechanical braking system of superior quality for this apparatus.
