Abstract: A tool for turning an elongate pipe is disclosed. The tool comprises a base and a drive wheel mounted for rotation on the base. The drive wheel has a cylindrical outer surface may include a plurality of projections extending radially outward from the outer surface of the first drive wheel. The projections extend past the edge of the base. In use, the projections contact a portion of the outer surface of an elongate pipe and turn the pipe with the rotation of the drive wheel. A guide is also mounted for movement on the base. The guide may be a pair of guide arms pivotally mounted on the base. Each guide arm has a free end and a guide roller is mounted for free rotation at each free end of each guide arm. Each guide arm is pivotable to a position wherein the guide rollers hold the elongate pipe against the projections on the outer surface of the first drive wheel.

Abstract: A propeller for use on low power motors, such as two-horsepower or less electric trolling motors, is provided with three or more blades on a hub wherein the hub diameter to the blade length (i.e. the length of the blade from the hub to the outermost tip) is in the ratio of at least 1.250 to 1. The hub diameter to blade length ration is such as to produce a propeller having increased performance and is substantially weedless. The width of each blade at its root is equal to or greater than the blade length and the ratio of the sum of the widths of the blades to the circumference of the hub is approximately 1.2 to 1. The true or actual pitch of the blades is measured at 0.7 the radius of the propeller and produces the best results as far as performance and weedlessness is concerned within the range of 2" to 7". The leading edge of one blade forms a junction with the hub in close proximity to a plane containing both the longitudinal axis of the hub and the junction of the trailing edge of the next adjacent blade.

Abstract: A cleaning apparatus as for inside surfaces in residential air ducts, employing a baffle that locally increases air velocity at the surface of the duct to the entrainment velocity that will remove dust and detritus with the help of reaction driven scouring elements for the mechanical dislodgement of dirt and dust. The dirt and dust can then be carried to a collection point by an induced flow of air through the duct. The invention also contemplates a method of cleaning a duct utilizing the above apparatus.

Abstract: A bait cast reel of the type having a line-carrying spool, a rotatable crank handle with an associated crank shaft for imparting rotation to the spool to wind line thereon, a line guide, and a worm gear operable in response to rotation of the crank shaft for causing reciprocative movement of the line guide across the spool as the spool is rotated to thereby evenly distribute line on the spool, wherein the structure of the guide track (guide) for the line guide, and, in particular, the cross-sectional shape of the guide, matches the cross-sectional shape of an opening in the frame of the reel such that during assembly the guide may be aligned with and inserted through the matching opening. Thereafter, the guide is rotated so that a portion is out of alignment with the opening and an attaching member is passed through the frame and through the out of alignment portion of the guide. The guide is positioned to support the line guide as the line guide is reciprocated to evenly lay the line on the spool.
