摘要： The present invention provides a method and apparatus for forming a plurality of parts, such as spade-type boring bits, from a continuous stock material. Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material prior to separating the continuous stock material into discrete parts, thereby enhancing the efficiency of the forming process. The present invention also provides an improved forge for forming portions of the continuous stock material into parts having a predetermined shape. The forge can be designed to provide a clearance region proximate the forward end of the ram to permit slight flexing of the forward end of the ram in a radially outward direction during forging operations. The forge can also include a lubrication system for lubricating its various components. In addition, the forge can incrementally rotate the ram after one or more parts have been forged. By repeating the incremental rotation of the ram, the forge will eventually rotate the ram a full 360°. An improved forging die is also provided which includes a back surface having a conical medial section and a pair of conical lateral sections that are recessed relative to the medial section such that forces will principally be applied to the medial section during forging operations.

摘要： The present invention provides a method and apparatus for forming a plurality of parts, such as spade-type boring bits, from a continuous stock material. Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material, prior to separating the continuous stock material into a number of discrete parts. The efficiency of the forming process is enhanced since individual parts need not be individually transported and oriented during the forming operations. By not requiring that the individual parts be separately transported and oriented during the forming operations, the quality of the parts formed by the forming method and apparatus of the present invention will also be enhanced since such separate transportation and orientation of individual parts generally increases the opportunities for misalignment and contributes to poor tolerance control during the manufacturing process.

摘要： A cutting tool (500) has a longitudinally extending shaft portion (588) with a chucking part (509) and a cutting head (506). A pressed powder cutting insert (518) with a cutting edge (520) is on the cutting head (506). The cutting edge (520) includes at least one cutting portion. A rake surface (524) is formed adjacent to at least one of the cutting portions (520) with the rake face (524) being at a rake angle from about 0.degree. to 10.degree.. A clearance face (526) is formed adjacent to the at least one cutting portion opposite the rake face (524). The clearance face (526) is at a clearance angle from about 10.degree. to 50.degree.. An edge radius (540) between the rake face (524) and the clearance face (526) is at a radius of from about 0.0015 to about 0.004 inch. The edge radius 540 is formed during pressing of the powder to form the insert, thus, enabling the insert to be directly braised into the cutting head (506).

摘要： A vacuum cleaner system having an electric powerhead with a first switch actuator component which can be actuated with a user's thumb, to turn on and off the powerhead, and a second switch actuator component which can be actuated with the user's foot, to also turn on and off the powerhead. The first switch actuator component is used when the powerhead is being used in a handheld cleaning mode. The second switch actuator component is used when the powerhead is being used in a floor cleaning mode along with an upright handle attached to the powerhead. An anti-tip over lockout system is incorporated for preventing the powerhead from being accidentally turned on when it is being held in an upside down orientation, such as during cleaning of a beater brush thereof.

摘要： A power cord retaining device for a portable AC powered tool. A retaining member holds the power cord plug engaged with a mating AC power jack in the housing of the power tool. The retaining member moves within the housing of the power tool from an unlocked position to a locked position. In one embodiment the retaining member slides within the housing of the power tool. In an alternative embodiment the retaining member rotates within the housing of the power tool. In the locked position the power cord plug is held in place engaged with the mating power jack in. the housing of the power tool. In one embodiment a release member having a biasing element locks the retaining member in place until it is manually unlocked by the user thereby permitting the retaining member to be moved away from the power jack to permit removal of the plug from the power jack. Another alternative embodiment incorporates a retaining member which is biased into engagement with a release housing portion of the power tool housing.
