Abstract:
A tool chuck may include an input shaft. A chuck actuating shaft may be mounted for rotation on the input shaft. A chuck actuating screw may be screw coupled to the chuck actuating shaft. A spring may be interposed between the chuck actuating shaft and the input shaft. Upon tightening the tool chuck, the spring may be compressed to provide force against the chuck actuating screw.
