  • Patent number: 5564852
    Abstract: The hot stick adaptor has two members that are adjustably movable relative to each other. A first one of the members has two separate first ratchet areas. A second one of the members has three separate second ratchet ares. A fastener and spring connect the two members to each other with one of the first ratchet areas and one of the second ratchet areas in interlocking engagement. The two members can be moved away from each other in a first direction, compressing the spring, to disengage the interlocking engagement and thereby allow the two members to be moved in a second direction.

  • Patent number: 5499557
    Abstract: A drain plug removing device including a removable socket located at the head of the device, which socket is adapted to securedly engage and hold the head of a threaded drain plug. The socket is fixedly coupled to the upper external member of a retaining socket holder, the lower section of which is disposed within a cavity of the device head in fixed engagement with a crown gear adapted for rotation within the cavity. A pinion gear is movably coupled within the head cavity to the crown gear. A tubular housing having a chamber in communication with the head cavity is fixedly connected to the device head. A drive shaft disposed within, and extending throughout the length of, the chamber is fixedly coupled at one of its ends to the pinion gear.

  • Patent number: 5370022
    Abstract: A fastener driving tool which uses the mechanical advantage of a lever to aid in the loosening and tightening of screws, bolts, nuts, and the like. The tool amplifies the force of a user that is exerted on a fastener bit (e.g. screwdriver blade) and a fastener head (e.g. screw head) thereby reducing the chance of the fastener bit slipping off the fastener head. A lever arm has a first end which attaches to an adjacent nearby screw or bolt. The fastener bit is attached to the lever arm and engages the targeted fastener head. The fastener bit functions as the fulcrum (i.e. the support about which the lever turns) of the lever arm. The user exerts downward force on the second end of the lever arm while using a conventional torquing tool (e.g. screwdriver, wrench, etc.) to loosen or tighten the hard to turn fastener.

  • Patent number: 5094134
    Abstract: A cutting pen with a bar-shaped cutter having a blade portion at one end thereof and a cylindrical holder into which the bar-shaped cutter can be inserted from the other end of the bar-shaped cutter. The holder has a radial bearing disposed corresponding to one end of the bar-shaped cutter and a thrust bearing disposed corresponding to the other end to support the inserted bar-shaped cutter in such a manner as to allow rotation around the axis thereof. The cylindrical holder attracts and holds therein the bar-shaped cutter by magnetic attraction, in such a manner that the work of attaching and/or detaching the bar-shaped cutter can be performed simply and easily in a short time, and the bar-shaped cutter is held firmly preventing it from falling off the cylindrical holder during use of the cutting pen.

  • Patent number: 5043007
    Abstract: A method for forming a binder-free granular or semi-granular fertilizer is disclosed, which comprises mixing a seed material and primary and secondary nutrient sources in a blender under heat until a slurry is formed, transferring the slurry to a long dryer, and drying the product under vacuum and thereafter gradually cooling the product to produce a granular or semi-granular fertilizer with a core of a seed material and a coating of secondary nutrient salts crystallized thereabout, with nutrients and biologically active agents entrained therein. The fertilizer formed has excellent stability and may be urea-free.
