I claim as my invention:
1. In combination, in a lathe-chuck, a sectional chuck-jaw, the two sections having flat meeting faces, a pivot-screw uniting the two sections, and a removable annular plug fitting corresponding sockets arranged opposite to each other in the meeting faces of the two jaw-sections, and the fastening screws whereby the sections are held from turning upon the pivot-screw, all substantially as described.
2. In combination, in a lathe-chuck, the chuck-body and the jaw-feeding devices, a chuck-jaw made in two sections and having flat meeting faces, the upper section extending the whole length and overlying the lower section, the pivot-screw uniting the two sections and upon which the upper section revolves, the removable annular plug extending into a socket in each jaw-section surrounding the pivot-screw, and the screws extending through opposite ends of the upper section, whereby it is held against rotary movement on the lower section, all substantially as described. |
