Abstract:
A tube and fitting preparation tool comprising, in combination:a base including a bottom plate with a substantially planar rectangular configuration having a periphery defined by a pair of elongated side edges and a pair of short end edges, a bottom face of the bottom plate of the base having a plurality of substantially disk-shaped pads mounted thereon at each of the corners thereof, the base further including an end wall with a substantially planar square configuration integrally coupled to the bottom plate of the base along one of the end edges thereof and extending upwardly therefrom in perpendicular relationship therewith and defined by a pair of vertical side edges and a horizontal top edge with a pair of beveled intermediate edges therebetween, an intermediate wall with a substantially planar square configuration integrally coupled to the bottom plate of the base between the side edges of the base and extending upwardly therefrom in perpendicular relationship therewith between the end wall and a center of the bottom plate of the base with the intermediate wall defined by a pair of vertical side edges and a horizontal top edge with a pair of beveled intermediate edges therebetween, a pair of substantially triangular apertured tabs integrally coupled between the side edges of the bottom plate of the base and the side edges of the end wall, and a pair of substantially rectangular apertured tabs integrally coupled to the side edges of the bottom plate opposite the triangular apertured tabs and extending upwardly from the bottom plate of the base;a plurality of linear shafts each rotatably coupled within bores formed in the end wall and the intermediate wall of the base in parallel relationship with the bottom plate of the base such that the shafts are positioned adjacent to the side edges of the end and intermediate walls and adjacent to top and bottom ends thereof, the shafts each having a first end with a substantially cylindrical chuck coupled thereto and positioned on an exterior surface of the end wall, a second end positioned adjacent to and spaced from one of the end edges of the bottom plate of the base, and a disk-shaped gear mounted thereon between the end wall and the intermediate wall such that the disk-shaped gears of the shafts remain in a single plane;a plurality of male attachments including a plurality of male brush attachments each having a linear rod for being removably coupled within the chuck of one of the shafts and a plurality bristles attached thereto and extending radially therefrom a unique predetermined distance, the male attachments further including a male auxiliary attachment including a linear rod for being removably coupled within the chuck of one of the shafts and four rigid substantially planar triangular plates fixedly coupled to the shaft and extending outwardly therefrom at 90 degree increments;a plurality of female attachments including a plurality of female brush attachments each having a first end with a socket adapted for removably securing to the second end of one of the shafts and a second end including a cylindrical casing having a plurality of bristles attached to an inner surface thereof and extending inwardly therefrom a unique predetermined distance with the second end of the female brush attachments residing flush with one of the end edges of the bottom plate of the base, the female attachments further including a female auxiliary attachment having a first end with a socket adapted for removably securing to the second end of one of the shafts and a second end including a cylindrical casing having four rigid substantially planar triangular plates fixedly coupled to an inner surface thereof extending inwardly therefrom at 90 degree increments with the second end of the female auxiliary attachment residing flush with one of the end edges of the bottom plate of the base;a motor having a stator coupled to a central extent of the intermediate wall of the base and extending therefrom away from the end wall of the base between each of the shafts in parallel relationship therewith, the motor further including a rotor extending between the intermediate wall and the end wall of the base with a disk-shaped gear mounted thereon in coplanar relationship with the disk-shaped gears of the shafts;a chain engaging an outer surface of the disk-shaped gears of each of the shafts and a lower surface of the disk-shaped gear of the motor for rotating the shafts upon the actuation of the motor;a cover including a top wall with an inverted U-shaped handle mounted thereon, a pair of upper beveled walls and a pair of side walls each having a lower edges equipped with bores for being screwably attached to the apertured tabs of the base, wherein an edge of each of the walls of the cover has an inwardly extending lip which defines an open end;a removable barrier with a substantially planar square configuration defined by a horizontal bottom edge, a pair of vertical side edges, and a horizontal top edge with a pair of beveled intermediate edges therebetween, wherein the barrier is removably attached to the open end of the cover and has a plurality of large bores formed therein for allowing access to the second ends of the female attachments; anda push button momentary switch positioned on the top wall of the cover and connected between a power source and the motor for selectively actuating the motor.
