Abstract:
1. An improved bit holding attachment usable with a power tool having a rotatable chuck with a cylindrical mounting section defining at least one locking aperture means therein, the rotatable chuck being adapted to receive and retain a first bit device therewithin, said improved bit holding attachment comprising: A. a housing means comprising: (1) a mounting end means; (2) a mounting cavity means defined within said mounting end means of said housing means and being open and facing outwardly therefrom, said mounting cavity means being adapted to receive and detachably engage the cylindrical mounting section of the rotatable chuck of the power tool therewithin to be movable therewith; (3) a forward cavity means in fluid flow communication with respect to said mounting cavity means and adapted to be able to receive at least a portion of a first bit device therewithin responsive to securement of the cylindrical mounting section of the rotatable chuck of the power tool within said mounting cavity means; (4) a forward end means including a forward bit securement means for detachably receiving and retaining of a second bit device therein; (5) an annular slot means extending peripherally around said housing means and said mounting cavity means defined therewithin; B. at least one locking pin means movably mounted within said housing means and being extendable at least partially into said mounting cavity means to be selectively movable into said mounting cavity means for extending thereof into a locking aperture means to facilitate detachable engagement of the cylindrical mounting section of the rotatable chuck of the power tool within said mounting cavity means of said housing means; C. a resilient biasing means positioned within said mounting end means of said housing means thereof at a position radially beneath said annular slot means, said resilient biasing means adapted to be in abutment with respect to said locking pin means for resiliently urging thereof inwardly toward a locking aperture means defined in the cylindrical mounting section of the rotatable chuck responsive to positioning thereof within said mounting cavity means to facilitate detachable engagement therebetween; and D. a capping ring removably positionable within said annular slot means at a position extending over said resilient biasing means positioned within said mounting end means of said housing means, the capping ring extending completely around a circumference of said housing means for facilitating retaining of said resilient biasing means therebelow.
