Abstract: A method of magnetizing a filter is disclosed. Magnetizing a filter improves the ability of the filter to remove ferromagnetic contaminants from a fluid by allowing the filter to attract and catch contaminants that have metallic properties. The method involves magnetizing the metal components of the filter, which include the filter canister, the filter end cap, the filter element frame, and any other components made from ferromagnetic materials.

Abstract: The present invention is directed toward a quick attach and detach mechanism for a tool attachment such as a router attachment for a router. The attachment system includes a mounting adapter which may be integrally formed with the router housing or attached to the router housing as a bolt-on plate. The system works by vertically installing the tool attachment with the mounting adapter and then twisting to secure the tool attachment to the mounting adapter. A rotational lock is provided to prevent the tool attachment from inadvertently backing off or coming loose. This lock can be manually actuated to allow for quick detachment when desired. The tool attachment system is shown in association with a router which has several disclosed benefits, however there may also be applications of the system in other types of tool attachments for which coverage is also sought.

Abstract: A method and apparatus are provided for constructing and operating an adjustable guide rail for hand tools, by attaching an elongated blade to a guide with a locking ratcheting apparatus. The locking ratcheting apparatus is thumb-operable. The elongated blade includes a first series of teeth. The guide includes the moveable thumb-operable latch. The latch has a second series of teeth which are selectively moveable into and out of engagement with the first series of teeth on the elongated blade for selectively preventing and allowing sliding movement of the elongated blade with respect to the guide. The teeth allow incremental adjustment of the guide rail apparatus.

Abstract: An angle drive attachment having an adjustable handle is provided. The angle drive includes an input shaft, an input shaft housing, a transmission, a handle mount, a handle, and an output socket. The handle allows the angle drive attachment to be adaptable to working environments having limited space or odd configurations. The input shaft rotates about the input axis of rotation and carried by the input shaft housing and drives the transmission. The output socket is connected to the transmission and rotates about an output axis of rotation and connects to a working bit. The handle mount mounts the handle to the input shaft housing. The handle, in cooperation with the handle mount, may be rotated about the input shaft housing, angled relative to the input shaft housing, and positioned axially linear along the input shaft housing.

Abstract: An apparatus and/or method for hanging a door in an associated frame are provided, through the use of one or more templates and/or guide devices including elements and features which facilitate proper positioning of mortises and/or holes in the door and door frame, for hinge and lock-set hardware.

Abstract: A removable surface positioning guide for a rotary hand-held tool provides one or more adjustable features for selective positioning of a surface engaging bit driven by the rotary hand-held tool. The surface positioning guide may include a pivot joint between a guide base and a mounting adapter. The guide base pivots relative to the mounting adapter about the pivot joint between operable positions. The surface positioning guide may include at least one spring supported by the mounting adapter either directly or indirectly that biases a guide base axially away from the mounting adapter. The guide base is movable toward the mounting adapter against the biasing of the at least one spring to effect a plunging movement. The surface positioning guide may include a reversible or interchangeable base flange with differently configured faces that are adapted to be placed against a working surface.

Abstract: An apparatus and method are provided for guiding the bit of a rotary hand tool along a corner of a work surface formed by two or more abutting surfaces, through use of a corner cutting apparatus which includes a corner cutting guide having a housing, defining an axis of the housing, and adapted for attachment of the rotary tool with the axis of the rotary tool extending through the housing along the axis of the housing. The housing also includes first and second guide walls, for engaging abutting walls at a corner of the work surface. The first and second guide walls are disposed substantially perpendicular to one another, and have respective outer surfaces which, if projected, would intersect to form a line lying in a common plane with the axis of the housing and oriented at an acute angle to the axis of the housing.

Abstract: A method and apparatus are provided for transporting, operating, and storing power tools and their accessories, through the use of a portable work center apparatus including a closable case having a work surface fixedly attached thereto, and storage compartments therein. The work surface is enclosed within the case when the case is in a closed position, exposed when the case is in an open position, and adapted for supporting a work piece thereupon. The work surface is adapted for having a tool removably attached thereto. The work surface includes a vise and the apparatus includes hold down devices for securing a work piece on the work surface.
