  • Patent number: 5562135
    Abstract: A combination woodworking tool is disclosed. The combination woodworking tool includes a frame having a horizontal bed for supporting workpieces. A rigid column is supported by the frame in proximity to and extends vertically upwardly beyond the horizontal bed. A powerhead is mounted to an upper end of the column in overlying relationship to the horizontal bed, the powerhead being vertically adjustable for movement toward and away from the horizontal bed. The powerhead further includes a motor and spindle which extends below a lower end of the powerhead. The spindle is adapted to interchangeably receive a chuck for use with a drill or a collet for use with a router. The powerhead is adjustably and rotatably mounted relative to the column for positioning the spindle in predetermined vertical, angular or horizontal positions relative to the horizontal bed for vertical, angular or horizontal drilling or routing.

  • Patent number: 5290210
    Abstract: Step exercise apparatus primarily intended for use in an aquatic environment such as a pool or the like. The apparatus includes a step platform maintained in elevated relation above a foundation surface by a pair of support members. The apparatus has a specific gravity greater than one so as to sink within a body of water, and slots extend through the platform to prevent entrapment of air bubbles when the platform is placed in a pool. Handles in the sides and ends of the apparatus assist the user in manipulating the apparatus while exercising in the water. Removable extension feet selectively increase the step distance between the platform and the pool bottom or other foundation surface on which the apparatus rests.

  • Patent number: 5036938
    Abstract: A riding scooter that may be assembled and dis-assembled without the use of tools is formed of components of a size and weight such that they may be handled by a person of modest physical strength. The scooter's front and rear sections have overlapping interengaging parts that are biased together in the operative position by the weight of the sections alone. Batteries for electrical power are contained within casings which are cooperatively retained within a battery housing and which also permit the batteries to be simultaneously electrically connected to the vehicle electrical system upon insertion of the battery casings within the battery housing. A steering tiller is detachably mounted to the front steering yoke being retained in an operative position by a quick release locking collar.

  • Patent number: 4360281
    Abstract: A reversible cam lock assembly is described. The cam lock assembly is adapted for attachment to a movable member and includes an eccentric cam for engaging a surface of a stationary member to resist movement inducing forces applied to the movable member. Depending on the orientation of the cam lock assembly, clockwise or counterclockwise rotational movement of the movable member relative to the stationary member is resisted.
