The holder includes a serration meshing with a serration of the adapter. Threaded holes are formed through the serration of the holder, and through-holes are formed in the adapter in alignment with respective holes of the holder. Screws extend through the aligned through-hole and threaded hole to secure the adapter to the holder. A slot intersects through one of the through-holes of the adapter to render the clamping portion elastically deformable. That through-hole includes a conically-shaped entrace surface, and the associated screw includes a conical head which acts as a wedge to force the clamping portion into clamping engagement with the insert.

  • Patent number: 6270296
    Abstract: A tool holder, which has a tool bit pivotal in a recess in one end thereof, extends coaxially through a generally bell shaped piston housing, and through the center of a piston slidably mounted on the holder for limited reciprocation in the housing axially thereof. The piston is urged by a compressing spring to a retracted position against one end of the housing, and has a reduced diameter annular wall that projects coaxially toward the end of the holder containing the tool bit. A tool actuating rod, which is pivotal in an axial bore in the holder, has on one end a lever which extends slidably into an axially extending helical slot formed in the annular piston wall, and is connected at its opposite end to the tool bit. When the piston is in its retracted position, the helical slot in its annular wall causes the actuating rod to swing the tool bit to an inoperative position within the holder recess.

  • Patent number: 6270298
    Abstract: The invention is directed to an improved cutting tool point. In the preferred embodiment, the cutting tool is comprised of a marginal end portion (15), adapted to selectively remove material from a work piece when the tool is moved relative to the work piece and having a leading cutting lip (16), a trailing dam (18), a recessed surface (19) extending into the marginal end portion between the cutting lip and the dam, and a coolant hole (20) communicating with the recessed surface, such that the recessed surface forms a reservoir (40) for coolant (36). The present invention also discloses a marginal end portion having an axis of rotation (42), at least one flute (21), and at least one chip-forming notch (31) extending from the flute into the marginal end portion and beyond the axis of rotation. The present invention also discloses a marginal end portion having a chip former (37) and a chip breaker (32).

  • Patent number: 6270304
    Abstract: The invention provides an improved Winged Fastener in which a large threaded nut is movably engaged with the threaded sleeve of the Winged Fastener wherein the nut is movable set in a washer such that the washer is placed against a surface, while the sleeve of the winged bolt is placed in a bore in a first matrix and a second matrix is set around the sleeve of the Winged Bolt. As the nut is turned on the threaded sleeve, the second matrix which is placed around the threaded sleeve is caused to be compressed and radially moved outward toward an inner surface of the first matrix. If the second matrix is of a rigid material, the cylinder of matrix is split longitudinally and the pieces are driven radially outward. The invention also provides a second improved Winged Fastener in which a hole is placed in a wing and a cable or tendon is attached to the wing through the hole.

  • Patent number: 6270305
    Abstract: A high-temperature conveyor furnace with a low friction conveyor travel surface is provided. The furnace includes a muffle defining a heating chamber, hearth plates providing a hearth surface within the heating chamber, and a conveyor belt to convey product through the heating chamber. The conveyor belt is formed of a first material, such as a nickel-chrome alloy. A plurality of low-friction inserts are supported by the hearth plates, preferably in openings in the hearth plates, to provide a surface upraised from the hearth surface upon which the conveyor belt travels. The inserts are formed of a second material, such as an electronics grade ceramic, that is different from the first material of the conveyor, which minimizes friction between the inserts and the belt. The low-friction surface is particularly suitable for high temperature, low dewpoint furnace applications, such as stainless steel brazing.
