Abstract

An attachment device for a rotary tool having an output shaft extending from the rotary tool housing is disclosed herein. The attachment device comprises an attachment housing defining a vacuum mouth. A fastening member is coupled to the attachment housing, and is configured to releasably connect the attachment housing to the tool housing. A fan is retained within the attachment housing. The fan is configured for connection to the end of the output shaft extending from the rotary tool such that rotation of the output shaft results in rotation of the impeller. Rotation of the impeller causes air and debris to be drawn into the attachment through the mouth. A debris container is coupled to the attachment housing and is configured to receive the debris drawn into the housing through the vacuum mouth.

Abstract

A router table comprises a table top, a bit mount, and a drive train. The bit mount is configured to hold a router bit such that the router bit extends from the table top defining a bit axis. The drive train is positioned under the table top and is operably connected between the bit mount and a drive coupling. The drive coupling is configured to engage a driven member, with the drive coupling defining a drive axis that is not coaxial with the bit axis. The driven member may be provided by a drive bit on a portable router secured to the table top. Operation of the portable router results in rotation of the driven member. Rotation of the driven member and associated drive coupling operates the drive train and results in rotation of the bit mount and associated router bit.

Abstract

A mandrel and accessory and related combination for use with a rotary tool are disclosed. For instance, the mandrel and accessory combination includes a mandrel assembly and an accessory. The mandrel assembly includes (i) a shaft component defining an axis and having a first portion configured to be received in a chuck of a power tool, and a second portion having a first shaft tooth and a second shaft tooth each extending in a perpendicular manner with respect to the axis, and (ii) a collar component defining a passage through which the shaft component extends, the collar component having a first collar tooth and a second collar tooth. The accessory includes an outer wall structure defining a circular outer periphery; and an inner wall structure defining a coupling opening. The accessory is configured to be releasably coupled to the mandrel assembly.

Abstract

A rotary tool accessory includes a body defining an axis of rotation and having a work piece contacting surface and a drive portion. The body has defined therein a body opening including a first opening portion and a second opening portion. The rotary tool accessory further includes an insert located within at least the second body opening. The first opening portion is contained within a space during rotation of the body about the axis. Both the drive portion and the second opening portion are advanced through a path during rotation of the body about the axis, the path being located outside of the space.

Abstract

A locking mechanism for a rotary power tool that includes an elongated locking member that is retained by, and is at opposite first and second end portions within, at least one of a motor housing and a gearbox end casting and being slideable between unlocked and locked positions, the locking member first end portion being accessible by a user to move the locking member to the locked position. The locking member also includes a locking portion intermediate the first and second end portions that is configured to engage the non-circular configured portion of a rotatable armature shaft and prevent rotation thereof when the locking member is in its locked position. A biasing element is also included and configured to bias the locking member toward said unlocked position.
