摘要： A multiple spindle drilling apparatus (10) having an eccentric drive link (11), and a primary drive mechanism (12) coupled to the drive link (11) in an eccentric off-set manner. This eccentric off-set causes eccentric circular motion of the drive link (11) about a predetermined radius (R). A frame member (15) is included, as well as a plurality of in-line spindle units (16) rotatably mounted to the frame member (15) for rotation about corresponding spindle axis (17) thereof. An off-set coupling (21) is rotatably mounted between the drive link (11) and respective crank members (20) mounted to corresponding spindle drive shafts (22) to drive the spindle about the spindle axis (17). The coupling (21) is eccentrically off-set from the spindle axis by a radial distance substantially equivalent to the predetermined radius, and further in-phase with the eccentric off-set of the drive link (11).

摘要： A process for designing and manufacturing precision-folded, high strength, fatigue-resistant structures and a sheet therefore. The techniques include methods for precision bending of a sheet of material (41, 241, 341, 441, 541) along a bend line (45, 245, 345, 445, 543) and a sheet of material formed with bending strap-defining structures, such as slits or grooves (43, 243, 343, 443, 542), are disclosed. Methods include steps of designing and then separately forming longitudinally extending slits or grooves (43, 243, 343, 443, 542) through the sheet of material in axially spaced relation to produce precise bending of the sheet (41, 241, 341, 441, 541) when bent along the bend line (45, 245, 345, 445, 543). The bending straps have a configuration and orientation which increases their strength and fatigue resistance, and most preferably slits or arcs are used which causes edges (257, 457) to be engaged and supported on faces (255, 455) of the sheet material on opposite sides of the slits or arcs. The edge-to-face contact produces bending along a virtual fulcrum position in superimposed relation to the bend line (45, 245, 345, 445, 543). Several slit embodiments (43, 243, 343, 443, 542) suitable for producing edge-to-face engagement support and precise bending are disclosed, as is the use of the slit sheets to produce various three-dimensional structures and to enhance various design and fabrication techniques.

摘要： A spade drill bit device including an elongated shaft formed for rotation about a longitudinal axis thereof, and a flattened blade portion at one end of said shaft. The blade portion has generally planar and parallel opposing faces, and defines opposing side edges, and an end cutting edge therebetween. The cutting edge includes a pair of opposing side spurs each having spur tip portions positioned at the lateral extremities of the cutting edge and terminates at the corresponding side edge. A cutting edge triangular-shaped center tip is included axially aligned with the longitudinal axis, and having a distal end extending beyond the side spurs. The center tip is defined by downward edge portions extending away from the distal end. The cutting edge further includes respective converging edge portions extending between and connecting each side spur to the center tip. Each converging edge portion intersects a respective downward edge portion at a corresponding curved nadir portion positioned closer to the center tip than the respective spur portion.

摘要： An apparatus (30) and method for forming an obliquely oriented counterbore (17) in a surface (15) of a workpiece (13) and a fastener receiving passage (19) proximate an edge (32) of the workpiece (13). The apparatus (30) includes a support frame (33), and a router assembly (34). The router assembly (34) is mounted for arcuate movement between a stored position, out of contact with the workpiece (13), and a routing position where a router bit (36) contacts the workpiece (13) to cut a tapering recess (1.7). A drill assembly (39) is movably mounted to the frame (33) for linear movement between a recessed position, out of contact with the workpiece (13), and a drilling position. In the drilling position, a drill bit (41) engages the workpiece (13) in a direction generally opposing the router bit (36) to drill the passage (19). A biasing assembly (43) is included independently biasing the router assembly (34) and the drill assembly (39) in generally opposite directions toward the stored position and the recessed position, respectively, to maintain the router bit (36) and the drill bit (41) out of engaging contact with one another.
