Abstract: An accessory for a bathtub has a tubular conduit that is placed around the rim of a bathtub and connected to the faucet. The conduit has outlets at locations along its length. When the faucet is turned on, fresh water is conveyed through the conduit to the outlets where the water leaves the conduit and enters the tub by washing down the sides of the tub in the manner of a waterfall. The conduit is non-metallic and supported by plastic or rubber elements. It can be conveniently installed and removed.

Abstract: Method for installing conduit in a confined wall space are disclosed. A tape is introduced into the confined space behind the wall and is extended to an outlet point by moving a tool along the exterior wall surface. The tool has an electromagnet which attracts a metal roller on the end of the tape, drawing the roller against the interior wall surface. The tool has rollers, or wheels, allowing it to roll on the exterior wall surface, and hence the extension of the tape is by means of combined roller action on both surfaces of the wall. At the outlet, conduit is attached to the tape and is pulled into the confined space by retracting the tape. Retraction of the tape may be accomplished by a drum onto which the tape is wound.

Abstract: An improved boring tool comprising a generally elongated housing member, an angle drive mechanism providing rotation about an axis at right angles to the housing member, and a unique floating boring bit which is slidably mounted upon the angle drive mechanism for axial movement along the axis of rotation. The boring bit features a central lead screw for drawing the bit axially into and through the workpiece over which the boring bit is placed as permitted by the floating mounting. A telescoping wall structure of the boring bit permits the bit to continue extending axially to complete penetration of the workpiece. An integral power source may be provided or provision made for the attachment of a portable electric drill or other readily available external power source. The cutting head of the boring bit may be removably mounted to facilitate replacement of worn cutting surfaces and to permit substitution of boring bits of different sizes for boring holes of different diameters.
