Abstract: In accordance with one aspect, a lawn sweeper for being towed by a lawn tractor including a body, a rotatable brush mounted to the body, and a motor for rotating the brush independently of the rotation of at least one wheel of the lawn sweeper. The lawn sweeper further includes a remote control for being operated by a user of the lawn tractor to control the motor. In another aspect, a lawn sweeper having a pair of wheels rotatable about a wheel axis, a body shiftable between raised and lowered positions relative to the wheels, and brush mounted to the body and rotatable about a brush axis. The brush axis is substantially vertically aligned with the wheel axis when the body is in the raised position and the lowered position.

Abstract: A coupling device is provided including a first coupling member or portion and second coupling member or portion where the second coupling member is configured to releasably engage the first coupling member. The second coupling member includes a locking sleeve or locking sleeve assembly slideably mounted on a cup body with the sleeve capable of being shifted toward an opening of the cup body to an unlocked position that permits insertion of the first coupling member into the second coupling member. The sleeve has an inner surface that covers and protects a fastening element positioned within bores of the cup body in both the locked and unlocked positions thereof. In one form, the locking sleeve assembly includes a locking device which restricts the sleeve from inadvertently shifting toward the unlocked position.

Abstract: An insert is disclosed for use in cutting tool applications having two major faces and at least two cutting edges. The insert is indexable by repositioning the cutting insert from one face to the other face. The inserts may be mounted in a seat formed in a fixed cutting tool. The seat has a major seating surface for mounting the insert and for receiving a retainer at a predetermined angle. In one form, the seat may also have dovetail walls oriented to engage side walls of the insert and to reduce the shear force against the retainer during contact between the insert and a rotating workpiece. The fixed tool has reliefs and a tip pocket to protect an unused cutting edge on the insert.

Abstract: An insert for use in a cutting tool having two truncated, wedge-shaped faces, and at least two edge surfaces. The insert also has a retainer hole extending through the insert at a predetermined angle to accommodate an insert retainer. The insert is indexable by repositioning the cutting insert from one face to the other face. The inserts are disposed in a plurality of circumferentially-spaced seats about a working end of a cutting tool body. Each seat has a major seating surface for mounting the insert and for receiving a retainer at a predetermined angle. The seat also has a minor seating surface oriented to engage an edge surface of the insert and to reduce the shear force against the retainer during rotation of the tool body. The tool body has angled chip pockets, resulting in more inserts per cutting tool diameter and a greater cross-sectional tool body.

Abstract: The present invention comprises a machining apparatus including a work piece holder having an adapter body with an axial bore and a translating portion located within the axial bore of the adapter body. The translating portion has a proximal end for coupling with a retention knob collet of a spindle and a distal end for attaching to a collet. The work piece holder includes a retaining piece coupling the adapter body and the translating portion allowing the translating portion to move axially within the adapter body. The apparatus facilitates a rotating spindle grasping and rotating a work piece to be brought into contact with a processing tool held stationary on a work table. The present invention also includes a fixture block for attaching milling tools and other devices to a work table and a method of operating a milling machine utilizing the fixture block and work piece holder.

Abstract: The specification and drawings describe and show a thread-rolling die whose thread-forming lands are modified at their points of emergence along the side edge of die so that the crest of the ramp formed by the emerging end of the land remains parallel to the crest of the adjacent land.

Abstract: A small diameter endmill and cutting insert therefor especially adapted to endmills of small diameter, e.g., three inches or less, by virtue of a cylindrically convex flank surface of radius of curvature preferably greater than the radius of the cutting path of the endmill.
