There is provided a structure for use in a power driven tool (1) for collecting dust generated by the operation of the tool. The structure includes: an outer housing; a commutation motor (5) disposed within the housing and including a main shaft (6) which has a tip end and a commutator (7) on the main shaft; a pair of brush assemblies (29) radially disposed around, and in contact with, the commutator of the motor; and a dust collecting fan (9) mounted on the main shaft of the commutation motor. The fan is disposed between the commutator and the outer housing. Also included are a dust intake passage (28) formed within the housing and having an intake (27) formed adjacent the location where dust is generated by the operation of the tool; a dust discharge passage (46) formed within the housing and having an outlet; and a dust chamber (43) formed substantially between the outer housing and the commutator for containing the dust collecting fan. The dust chamber has a first connecting portion (35) coupled to the dust intake passage and a second connecting portion (40) coupled to the dust discharge passage. The first and second connecting portions are arranged around the main shaft where they do not overlap the brush assemblies in the axial direction of the main shaft.
An apparatus for supporting an abrasive material includes a flexible base defined by a first end and a second end, and by a lower surface which supports the abrasive material and an upper surface opposite the lower surface. The flexible base is fabricated from a resilient material so as to assume an essentially flat shape when the ends of the flexible base are not acted on by external forces. A front frame is member attached to the flexible base proximate the first end, and a rear frame member is attached to the flexible base proximate the second end. An adjustable connecting link has a first end connected to the front frame member in fixed relation thereto. A second end of the adjustable connecting link is connected to the rear frame member by a variably positionable connection.
A Belt Sander Eraser Attachment is disclosed. The attachment is configured to be attached to a conventional belt sander such that it provides the operator with the ability to remove built up sawdust and the like from the sanding belt. The device removably replaces the conventional front handle on a sander and the new handle has functionality as both a handle and an actuator for the belt sander eraser. The eraser actuation is convenient and ergonomically comfortable for the user while the sander is in use.
A belt sander (2) comprising a housing (4) and having a lower sanding surface (40) and an upper sanding surface (42) opposite the first sanding is disclosed. The sander has a larger rear roller (32) driven by a motor (22), a front roller (34) of smaller diameter than the rear roller, and an endless sanding belt (38). A guard (48) is pivotable between a lowered position preventing access to the upper sanding surface and a raised position allowing access to the upper sanding surface. A handle (12) on the housing is pivotable between a first handle position adjacent the upper sanding surface and at least one second handle position further from the upper sanding surface than the first handle position.
An electrically powered belt sander comprising a housing, a dust flow path defined by the housing, a motor mounted in the housing at a first location and having an output shaft, a fan connectable to the motor output shaft and rotateably mounted in the housing at a second location a distance from the motor output shaft, a belt connectable between the motor output shaft and the fan whereby the rotation of the motor output shaft drives the rotation of the fan, and a damper located in the dust flow path and operable for blocking the dust flow path.
