  • Patent number: 8573098
    Abstract: A cutting tool has a cutter body, which carries a cutting insert, and an adapter, which has a longitudinal adapter axis, wherein a locking screw attaches the cutter body to the adapter. A coolant volume is defined in a vicinity of a meeting of the cutter body, the adapter and the locking screw. The adapter contains an axial adapter bore. The locking screw contains a transverse locking screw bore in fluid communication with the axial adapter bore. The locking screw further contains a peripheral transverse locking screw bore passage in fluid communication with the coolant volume and the transverse locking screw bore. The coolant volume and the transverse locking screw bore are in fluid communication with the cutter body coolant passage.

  • Publication number: 20130202345
    Abstract: A pin assembly for a retractable pin mechanism of a slider box of a heavy-duty vehicle includes a pin guide attached to the slider box. A pin is connected to a retraction mechanism and engages the pin guide. The pin includes an integral inboard and outboard stop. The integral inboard and outboard stops of the pin limit movement of the pin with respect to the pin guide and serve as a positive stop for the pin during retraction and extension of the pin when the retraction mechanism is activated or deactivated by the operator of the vehicle.

  • Publication number: 20100008735
    Abstract: A milling cutter includes a shank having an insert pocket and a cam pin hole. The insert pocket includes a bottom surface, a radial seating surface and an axial seating surface. A cutting insert is mounted in the insert pocket. The cutting insert includes a blind hole extending from a bottom surface. A cam pin is rotatably mounted in the cam pin hole. One end of the cam pin includes a raised boss received in the blind hole of the cutting insert. A center axis of the raised boss is offset from a center axis of the cam pin such that rotation of the cam pin causes the raised boss to exert pressure against the blind hole of the cutting insert, thereby causing one of the side walls of the cutting insert to be forced against the radial seating surface of the insert pocket.

  • Patent number: 7204662
    Abstract: A cutting tool includes a tool body having a plurality of insert receiving pockets and at least one cutting insert mounted in each pocket. Each pocket includes a pocket base wall, a side wall and a stress relief groove. The tool body also includes a top surface including a first portion and a second portion, and a stress splitter that extends from the stress relief groove and intersects the first and second portions. The stress splitter may be in the form of a sharp peak or ridge, a radiused peak, rounded mass or protuberance, and the like. The stress splitter reduces a maximum amount of stress in an area of the stress relief groove during a machining operation.

  • Patent number: 7121770
    Abstract: A cutting tool body that is adapted for use in milling operations comprises at least one pocket for supporting a cutting insert. The pocket is defined, at least in part, by a cylindrical wall and a seating surface within the tool body. At least one passage is provided through the tool body for evacuating chips upward and away from the surface of a workpiece. The seating surface of the pocket extends radially inward from the cylindrical wall and intersects the passage through the tool body. At least one slot traverses the pocket to separate a part of the tool body into first and second portions, at least one of which is movable relative to the other for clamping the cutting insert into the pocket.

  • Patent number: 6702526
    Abstract: A cutting tool comprises a cutter body having at least one pocket therein. The pocket is adapted to receive a cutting insert cartridge. A position-adjusting device cooperates with the cartridge to move the cartridge in opposing directions. The body may have a pocket for receiving the cartridge. The device may include a cylindrical body member supported in a fixed axial relation within a bore in the body. The cylindrical body member may have an eccentric protrusion that engages the cartridge. The cylindrical body member may be displaceable to displace the protrusion and move the cartridge. A clamping wedge may be provided for clamping the cartridge in the pocket. The protrusion may engage a slot in a rear surface of the cartridge. The protrusion may engage the slot.

  • Patent number: 5563766
    Abstract: A smoke detector or alarm includes on its lower side a cylindrical cup which may be lined with ribbed foam rubber. The inside diameter formed by the liner is designed to mate with the end of a broom or mop handle so that the cup forms a reasonably firm fitting socket for the handle end. A wedge shape triangular adapter plate is mounted on top of the smoke detector and slightly spaced from the top by a round vertical stud. Secured either directly to the ceiling or to the usual smoke detector mounting fasteners is a receiver into which the adapter plate fits. The receiver is in the form of a horizontal wedge shape triangular slot, the bottom of which has a blind slot to accommodate the stud of the adaptor. The bottom of the entrance to the receiver is provided with a lip over which the adapter plate must move. The smoke alarm may accordingly be readily removed and replaced for battery changing, servicing, and testing without the use of a step ladder or step stool.

  • Patent number: 4716808
    Abstract: Apparatus for sequencing the release of a missile from its launch apparatus, the unlocking of the missile's warhead fuze pre-launch safety lock, and the ignition of the missile's rocket motor. A cylindrical block having a radial passageway is situated between the warhead and the rocket motor of a missile. An actuator piston having a hollow cylindrical core slides within the passageway. One end of the actuator piston projects from the passageway and is engaged with the launch apparatus to prevent movement of the missile relative to the launch apparatus prior to launch. A source of pressurized gas communicates with the hollow core of the actuator piston through an opening in the actuator piston's projecting end. A notch in the side of the actuator piston is engaged with the warhead fuze pre-launch safety lock.

  • Patent number: 4273990
    Abstract: A baseboard heater for mounting against a wall and spaced from the floor comprises a casing having an open bottom and upper front side which permits the free upward and then forward free flow of air therethrough. An elongated electrical heating element mounted therein adjacent the open bottom thereof is provided with a high temperature cut-off switch. A switch actuator including a sensing tube coextending alongside the heating element is cooled by incoming air to preclude switch actuation but is quickly heated by the heating element to effect cut-off when airflow is blocked.
