Description: |
"Our invention relates to that class of lathe-chucks whose jaws are moved radially in guide ways or slots made in the front face of the shell or case by a rotary disk operated by pinions within the shell, and provided with a convolute or scroll thread made on its outer face, which engages in the teeth made on the back side of each jaw. The object of our invention is to secure the greatest strength, durability, and accuracy in and to completely inclose all the actuating parts, to give easy access to the same when desired, and to provide means to secure the back plate to the shell at the same time the chuck is secured to the chuck-plate..." |
