A mechanism for the lathe-working of longitudinal, cylindrical, or slightly conical work-pieces (88), preferably cartridge cases for firearms, which uses at least two driven rotating spindles (80) located in a housing (17). The housing (17) is rotatable around an axle (16) and is rotated by a hydraulic or pneumatic cylinder (22, 23) into a series of operating positions. Tools for working the cartridge cases (88), (a) a shaper for the extractor groove (93) and the extractor flange (92) and (b) a cut-off piece (103), are both attached to a cut-off sled (101). This cut-off sled (101) is guided back and forth on a main sled (94) laterally with respect to the axis of rotation of a spindle (80). The main sled itself may be moved in the direction of the axis of rotation of the spindle (80). In this manner, the length of the cartridge case is determined exactly. Furthermore, each rotating spindle (80) is driven individually. Through use of a clutch (67), each rotating spindle can be selectively connected to a drive motor. In this way, only one rotating spindle is driven at any particular time while the others are not driven. Thus, the loading time is shortened and the loading process simplified.

Mechanism for lathe-working articles

A spindle drive for measuring devices comprises a threaded spindle with a nut threadably engaged on the spindle and with one of them being rotatable to cause displacement relative to the other along a longitudinal direction in relation to the spindle. A nut carries a slide portion with vertically extending posed blind bores carrying bushings with ball races therein. A measuring carriage is affixed and forms part of a support portion which extends over the slide and the measuring carriage portion extend below the slide. A drive pin is carried by the support portion and the measuring portion and it is confined for movement within the respective bushings. A screw bolt is connected between the support portion and the slide and it may be threadably adjusted to permit vertical adjustable positioning of the slide relative to the measuring carriage and the support portion.
