  • Patent number: 10767375
    Abstract: A mechanism to secure the base of a pole to the lid of a flatbox finisher is provided. The mechanism utilizes at least one spring grasping device on the lid of the flat box finisher to grasp and secure the base of the pole. The grasping mechanism is depressed and grasps a generally flat rectangular edge of the base of the pole and secures the base of the pole to the lid of the flatbox finisher by friction. In particular, as the base having the pole of the flatbox finisher is first slid over the grasping mechanism, the grasping mechanism is first pushed downward. After the base slides over the grasping mechanism, the grasping mechanism springs back upward and locks the base of the pole into place on the lid of the flatbox finisher.

  • Patent number: 10378221
    Abstract: A drywall mud applicator wheelless control tube is provided. The drywall mud applicator wheelless control tube has a plastic component (in an embodiment) having a rubber o-ring or spring which provides pressure to a slanted cylindrical ledge protrusion which allows the control tube to slide up and down a main mud applicator tube without the need for wheels on the control tube. As a result, the wheelless control tube increases the sliding and smoothness of the control tube as it slides over the main mud applicator tube.

  • Patent number: 8381789
    Abstract: An automatic drywall taper is provided. The automatic drywall taper has a securing device for securing drywall tape to the body of the taper during use. The securing device has an elongated bar which runs substantially parallel to the body of the taper. The elongated bar is spring activated to lock a hub on a bar which is attached substantially perpendicular to the body of the taper. The hub rotates thereby allowing the tape to dispense and be used on drywall. The hub has a braking mechanism which allows for the controlled release of the tape.
