Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
226 words
A radius turning lathe comprising: a. a base member having a dovetail slide and a spindle having a longitudinal axis parallel to said slide, b. a carriage member mounted for longitudinal reciprocation on said slide and having a slide surface engaging said slide and side surfaces spaced from the dovetail of said slide, c. said surfaces forming a U-shaped channel for receiving said slide, d. adjustment members positioned between each of said side surfaces and said dovetail slide, e. said adjustment members comprising tapered gibs having straight surfaces conforming to said side surfaces and angled surfaces conforming to the dovetail angle of said slide, f. said gibs being reversed end for end with respect to each other, g. screw means for moving said gibs longitudinally thereby moving said carriage member laterally on said base member, h. plate means attached to said carriage for securing said gibs against vertical displacement, i. a tool member, j. means mounted on said carriage for mounting said tool member for pivotal movement about a vertical axis, k. positive vertical adjustment means for vertically positioning said tool member, l. means for positively shifting the relative longitudinal position of said tool member and said vertical axis, m. said adjustment members and said positive vertical adjustment means serving to precisely position and hold the cutting tip of said tool member on said longitudinal axis.
Claim 2
Dependent Claim
226 words
A radius turning lathe comprising: a. a base member having a dovetail slide and a spindle having a longitudinal axis parallel to said slide, b. a carriage member mounted for longitudinal reciprocation on said slide and having a slide surface engaging said slide and side surfaces spaced from the dovetail of said slide, c. said surfaces forming a U-shaped channel for receiving said slide, d. adjustment members positioned between each of said side surfaces and said dovetail slide, e. said adjustment members comprising tapered gibs having straight surfaces conforming to said side surfaces and angled surfaces conforming to the dovetail angle of said slide, f. said gibs being reversed end for end with respect to each other, g. screw means for moving said gibs longitudinally thereby moving said carriage member laterally on said base member, h. plate means attached to said carriage for securing said gibs against vertical displacement, i. a tool member, j. means mounted on said carriage for mounting said tool member for pivotal movement about a vertical axis, k. positive vertical adjustment means for vertically positioning said tool member, l. means for positively shifting the relative longitudinal position of said tool member and said vertical axis, m. said adjustment members and said positive vertical adjustment means serving to precisely position and hold the cutting tip of said tool member on said longitudinal axis.
Claim 3
Dependent Claim

Claim 8
Dependent Claim
40 words
A lathe as in claim 6 and including: a. a tool holder for said tool member mounted in said vertical slide, b. said precision vertical adjusting means including means for positively vertically moving said tool holder in said vertical slide.
Claim 9
Dependent Claim
21 words
