  • Patent number: 11175047
    Abstract: A pellet stove includes a hopper for storing pellets, a basket for receiving the pellets by gravity, a duct for conveying combustion air to the basket, and a conduit for conducting heated air away from the basket. The position of the basket is adjustable, such as by raising and lowering it, or by rotating it, so as to control the number of pellets in the area of most intense combustion. One or more optional burn plates, positioned below the basket, provide platforms on which pellets falling through the basket can burn down to a smaller size. The pellet stove requires no external source of power. The stove so constructed enables quiet, efficient and clean burning of the pellets.

  • Patent number: 6401338
    Abstract: A method of removing a bearing insert from a skate wheel is performed utilizing a bearing insert tool. The bearing insert has a central axial bore corresponding to the diameter of a central axial bore of a spacer element. A transverse bore is formed through a middle portion of the spacer element. The spacer element middle portion has a larger outer circumference than that of its opposed side portions. The spacer element opposed side portions mount within the inner circumference of the bearing inserts such that inner side walls of the bearing inserts abut opposed side walls of the spacer element middle portion. The bearing insert tool has a shaft containing spring activated nipples on a distal end. A button on the tool head portion operates the spring. To remove the bearing inserts the button is depressed retracting the nipples. The shaft is then inserted within the central axial bore of the spacer element through the proximal bearing insert.

  • Patent number: 4473946
    Abstract: A pyrographic iron for sculpting fine feather barbs on a realistic wooden bird carving uses interchangeable tips slide fitting on the irons. The tips have a head with a flat surface tapered toward one or two outer edges, the surface having from 3 to 100 serrations per inch extending outwardly on the head to the outward edge or edges. The serrations form crests and valleys, the crests charring the barb lines and the valleys limiting the depth of charring.

  • Patent number: 3942281
    Abstract: A streamline-configured fishing lure is molded of plastic with a uniformly distributed intermixture of granular weighting material, such as limestone, in a proportion to impart to the lure a specific gravity and in consequence thereof motions in water comparable with the specific gravity and motions of lures, formerly plentifully available but generally no longer available, that were carved from natural substances such as bone, ivory and horn. A leader for this or any type of lure, whether for casting, trolling or jigging, comprises a barbed hook arranged to have the free end of its shank coupled to a line and the opposite end of the shank coupled to the lure, the shank having flexible feathers secured thereto to form a shroud surrounding the hook.
