Title: CHUCK ACTUATOR SYSTEM AND METHOD
Abstract: A keyless chuck operating system comprises a hollow, generally cylindrical body (12) formed of rubber or other similar substance preferably having a shore hardness in the range of 50 to 60. The body has a central cavity (22) therein formed to fit firmly over a chuck locking drum (100). Tightening the jaws is accomplished by adjusting the drill for ordinary drilling with a right handed bit, firmly grasping the outer periphery of the chuck operating device, and then turning on the drill. Loosening the chuck jaws is done in a manner similar to tightening them except that the drill is adjusted to reverse the direction of rotation. The chuck actuation may include a plurality of gripping beads (16, 18) in the passage that receives the chuck body for gripping the chuck when the rotary tool is actuated. The outer periphery of the chuck operating device preferably has a plurality of indentations (28) thereon to facilate manual gripping of the device. The body may have a plurality of longitudinally aligned holes (20) therein between its inner and outer edges. These holes permit the use of less material to make the device than if it were a solid body. The holes also assist in compressing the inner portion of the device around a chuck. The system includes a mounting adapter (90) formed generally as a frustocone that fits inside the chuck operation device, which is then slid from the mounting adapter onto the chuck drum.
