Abstract
Abstract The horizontal-spindle lathe comprises a bed located within the dihedral angle formed by the two geometrical half-planes which extend from the geometrical axis of the spindle respectively above and behind said axis. Two pairs of slideways on which are mounted respectively two longitudinal-traverse carriages are located respectively on a front longitudinal face and on a bottom longitudinal face of the lathe bed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
A horizontal spindle lathe comprising, a frame, a workpiece spindle headstock rigidly secured to said frame, a workpiece spindle rotatably mounted in said headstock and having a horizontal axis, a single elongated bed rigidly supported by said frame and extending in parallel relation with said workpiece spindle axis, said bed being located within the dihedral angle formed by two geometrical half planes extending horizontally to the rear of and vertically upwardly from said axis of said workpiece spindle and having a front longitudinal face and a bottom longitudinal face, a pair of front slideways extending longitudinally on said front face and a pair of bottom slideways extending longitudinally on said bottom face of said bed, and a front and bottom cutting tool-carrying carriage mounted for sliding movement on each of said front and bottom slideways.
Claim 2
Dependent Claim
135 words
A horizontal spindle lathe comprising, a frame, a workpiece spindle headstock rigidly secured to said frame, a workpiece spindle rotatably mounted in said headstock and having a horizontal axis, a single elongated bed rigidly supported by said frame and extending in parallel relation with said workpiece spindle axis, said bed being located within the dihedral angle formed by two geometrical half planes extending horizontally to the rear of and vertically upwardly from said axis of said workpiece spindle and having a front longitudinal face and a bottom longitudinal face, a pair of front slideways extending longitudinally on said front face and a pair of bottom slideways extending longitudinally on said bottom face of said bed, and a front and bottom cutting tool-carrying carriage mounted for sliding movement on each of said front and bottom slideways.
Claim 3
Dependent Claim
79 words
A horizontal spindle lathe according to claim 1 and further comprising a cross-slide mounted on each of said carriages, cutting tools operatively mounted on each cross-slide, a control device mounted at the upper portion of the cross-slide on the carriage mounted on said front slideways and operatively engaged therewith for controlling movement thereof, and a control device mounted at the rear portion of the cross-slide mounted on said bottom slideways and operatively engaged therewith to control the movement thereof.
Claim 4
Dependent Claim
36 words
A horizontal spindle lathe according to claim 1, wherein said workpiece spindle headstock has a top face located at a level not higher than the path of travel of the carriage mounted on said front slideways.
Claim 5
Dependent Claim
68 words
A lathe according to claim 1, wherein said front and bottom faces extend in planes which intersect to form a common line, each pair of slideways comprises a guiding slideway and a retaining slideway and the two guiding slideways are located in the immediate vicinity of said common line of intersection of the planes of the front longitudinal face and the bottom longitudinal face of the lathe bed.
Claim 6
Dependent Claim
17 words
A lathe according to claim 1, wherein the front longitudinal face of the lathe bed is vertical.
Claim 7
Dependent Claim
17 words
A lathe according to claim 1, wherein the bottom longitudinal face of the lathe bed is horizontal.
