Abstract
A chuck jaw assembly includes a base and a removable jaw. A tongue and groove interconnection is provided between the base and the jaw in the form of a longitudinally tapering dovetail. As the tongue is pushed along the groove, its sides are tightly wedged within the groove. At the same time, the tongue is pulled downwardly into the groove so as to firmly seat the jaw on the base.
Claims15
A chuck jaw assembly, comprising:
- a base;
- a jaw removably mounted to said base;
- and
- a double-tapered tongue and groove interconnection provided between said base and said jaw for mounting said jaw on said base, said interconnection comprising a tapered tongue having a pair of converging sidewalls, a complementary-tapered groove having an inner floor and a pair of groove sidewalls converging along opposite sides of said groove and receiving said tongue sidewalls therein with a transversely wedged interfit, at least one undercut extending longitudinally along said groove, and one of said sidewalls projecting into said undercut and wedged into said groove and forced toward said inner floor by abutment along said undercut, and wherein said tongue is spaced apart from said inner floor of said groove.

A chuck Jaw mountable to a base, comprising:
- a first end portion;
- a second end portion spaced longitudinally from said first end portion;
- a pair of abutment surfaces located between said first and second end portions for mounting said jaw to said base;
- first and second side surfaces extending longitudinally between said first and second end portions;
- and
- a tongue projecting outwardly from between said abutment surfaces for connecting said jaw to said base, said tongue comprising a compound dovetailed wedge having a first wedge extending longitudinally between said front and rear end portions, said first wedge comprising a pair of longitudinally converging sidewalls for centering said jaw on said base, and a second wedge extending transverse to said first wedge, said second wedge defined by said sidewalls diverging laterally from between said abutment surfaces for clamping said base between said abutment surfaces and said sidewalls.
