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.

Abstract: A cutting tool, such as a slotting cutter, includes a support disc rotatable in a predetermined direction on a central axis. The support disc is of a generally cylindrical shape has a plurality of cartridge-receiving pockets. A cartridge assembly is capable of being mounted to the pocket and includes a cutting insert with at least one cutting edge secured to each cartridge assembly. The cartridge assembly includes a tapered, threaded hole for receiving a tapered, threaded screw. The threaded hole is off-center to divide the lower portion of the cartridge assembly into two portions having different thicknesses and flexibility. A slot extends from the threaded hole to a bottom face of the cartridge assembly. The cartridge assembly expands as the tapered, threaded screw is received in the tapered, threaded hole to secure the cartridge assembly in the pocket.

In a preferred embodiment having three flutes, the flutes are mostly not centered on one hundred twenty degree intervals. In the second irregularity, at least some pockets are arranged at different radial rake angles. In the third irregularity, at least some pockets are arranged at different axial rake angles.

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.

Abstract: A cutting tool including a cutter body and a locking screw. The cutter body has one or more pockets for receiving one or more cutting inserts and at least one channel for delivering coolant from a milling machine to the cutting inserts.

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.

Abstract: The cutting tool includes a cutter body having at least one pocket therein adapted to receive a cutting insert cartridge assembly. The at least one pocket has a forward wall, a rearward wall and a bottom wall. The bottom wall extends between the forward wall and the rearward wall and is arranged at an angle greater than 90 degrees relative to the forward wall and is arranged at an angle less than 90 degrees relative to the rearward wall. The insert cartridge assembly includes a cartridge and a clamping wedge. The cartridge has a front surface, a rear surface and a bottom surface and an insert pocket for receiving the cutting insert. The bottom surface is shaped to correspond to the bottom wall of the pocket, and the rear surface is shaped to correspond to the rearward wall of the pocket. The clamping wedge is of a dove tail shape and includes a forward wedge surface and a rear wedge surface.

Abstract: An indexable cutting insert (10) having a top surface (12) including a substantially planar central portion (48), a substantially planar bottom surface (14), and a plurality of side surfaces (16, 18, 20, 22). A long cutting edge (24, 26), a corner radius cutting edge (28, 30), a facet radius cutting edge (32, 34), and ramping cutting edge (36, 38) are defined at an intersection between the top surface (12) and one of the side surfaces (16, 18, 20, 22). A margin (87, 89) extends around a nose radius of the cutting insert (10) and blends into a flat surface (94, 96). A margin angle, C, formed by the margins (87, 89) is less than a seating angle, B, formed by the flat surfaces (94, 96).

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.

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.

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.

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.
