  • Patent number: 6148523
    Abstract: A line trimmer head (10) includes a line feed configuration which facilitates reloading the head (10) with new line without requiring removal of the spool (24) from the housing. Line (18) is sequentially fed first into the housing through a peripheral opening (20) in the housing, through a guide channel (84, 86) in the spool, and then out of the housing beyond a lower flange (26) of the spool through an opening in the hub (98) of the spool. Finally, the line is fed into a small opening in a spool flange (94) to secure the line with respect to the spool. Rotation of the spool then 46 causes the line to be drawn into the housing through the peripheral opening and wrapped around the spool. The spool provides separate storage compartments (38, 40) for different lines. Additional payout of line is provided when a bump knob is bumped on the ground surface.

  • Patent number: 5634748
    Abstract: A drill press assembly having a base mountable to a work bench, a vertical column attached to the base and a drill head assembly having an electric motor and a quill. The drill head assembly is movably attached to the column. A rack is rotatably attached to the top of the column and is engaged by a crank and pinion mechanism attached to the frame of the drill head assembly which permits the drill head assembly to be displaced vertically and rotated about the column. A tilt table is attachable to the base of the drill press. A locking mechanism having a bolt passing through a longitudinal slot in the supporting base of the tilt table and a transverse slot in the base is engaged by an eccentrically mounted camshaft to lock the supporting base of the tilt table to the top surface of the drill press base. A pivoting frame is pivotably attached to the supporting base and contains a table plate. A fence is attachable to the top of the pivoting frame.

  • Patent number: 5337626
    Abstract: A laminated gear and a method of forming the laminated gear are disclosed. The method comprises punching a central hole and a circular array of closely adjacent perforations in a generally planar sheet. The array defines an interior portion having the outline of the gear, and a selvedge portion disposed outboard the perforations. The central hole and the perforations are progressively stamped until they have burnished faces perpendicular to the sides of the sheet. Web portions interconnecting the interior and selvedge portions are then broken to separate the gear from the sheet. A projection and corresponding recess are then stamped on the opposite sides of the gear. A predetermined number of gears are queued and finally arranged into an assembly by frictionally nesting the projections and corresponding recesses. The central holes are thereby aligned to form a bore adapted to be press fit onto a camshaft or crankshaft. The laminated gear formed by this method is also disclosed.

  • Patent number: 5320150
    Abstract: A collapsible stand having a top (14) formed by two mating leaves (15, 17) and supported by legs (28, 30, 32, 34). The legs are pivotedly joined to braces (20, 22, 24, 26) underlying the leaves. The components of the stand pivot with respect to one another so to allow the stand to be easily erected and collapsed. However, due to interaction between at least one of the braces and at least one retainer (64) on the underside of one of the leaves the stand cannot be collapsed without initial planar movement of the leaves away from one another. Since such movement is rare during normal usage, the stand is strong and secure during normal usage. A pair of brackets (80, 82) for holding dimensional lumber (79) may be attached to the braces. When the lumber is placed in the brackets, the stand is further secured in its erect position.
