  • Patent number: 6644000
    Abstract: A protective device 104 for hoofed and shod animals fabricated of a durable and flexible material is presented. The protective device 104 includes a base 106 and a wall 108, with the wall designed to enclose a hoof 100 of a bare or shod animal such as a horse or cow. The protective device 104 includes a means for size adjustment 216 such as a sizing opening 214 in combination with a plurality of tread grooves 304, which assists in the adjustment of the size and shape of the hoof to fit a variety of hoofs. The protective device 104 preferably includes a shear-relief portion 302 formed such that the front of a hoof has minimal contact with the device 104. Ease of installation, decreased impact, and improved traction are all benefits provided by the protective device 104 disclosed.

  • Patent number: 6247230
    Abstract: An improved impact tool head having separate and distinct pressing and cutting blades integrally molded therein. The impact tool head allows for independent and optimal material and dimensional design of the pressing blades and the cutting blades to minimize impact damage to a terminal block and to ensure longer useful tool life. Also, through the use of multiple components, the impact tool head is readily adaptable to a wide variety of different terminal block configurations. Furthermore, sets of pressing blades and sets of cutting blades may be formed with each set comprising a continuous piece of material in order to simplify manufacturing and to ensure uniformity of production. Additionally, the integral molded structure is designed to allow post-molding sharpening of the cutting blades in order to ensure blade uniformity to further improve blade durability.

  • Patent number: 4694770
    Abstract: A watercraft stabilizing flotation structure comprising two hulls (23) (25) that surround the outside perimeter of a single-person ski-type powered watercraft to extend the surface area in contact with the water. A seat (36) located at the stern allows the operator to sit during operation of the craft. A removable pin (34) secures the placement of the watercraft at the bow and a pair of straps and buckles (27) hold the hulls (23) and (25) together. The hulls are hollow and watertight providing a flotation chamber for the structure. In another embodiment a set of running lights (48), (50) and (52) are provided for operation in navigable waters. The lights are wired integral with the structure and are energized either by the watercraft's ignition system or an independent battery. A mechanically operated thrust reverser (54) may also be incorporated adjacent to the back of the seat assembly (36), behind the water discharge, to allow the watercraft to reverse direction or add braking capability.
