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.
Claims3
A tape securing device for an automatic taper comprising:
- a rotating hub having a generally circular first flat surface;
- a generally cylindrical body located on the rotating hub wherein the generally cylindrical body has a plurality of planar surfaces extending outward from the generally cylindrical body and wherein the plurality of planar surfaces are located substantially perpendicular with respect to the generally circular first flat surface and wherein the rotating hub rotates around a shaft and wherein a drywall tape is placed on the generally circular first flat surface and at least partially around the plurality of planar surfaces;
- and
- a generally wedge-shaped brake located between two of the plurality of planar surfaces of the hub wherein the generally wedge-shaped brake moves from a first position to a second position and wherein the movement of the generally wedge-shaped brake from the first position to the second position alters a diameter of the hub and therein accommodates tapes of various sizes.
