Abstract
Abstract A turning lathe wherein the headstock for the work spindle mounts at least one first support. The first support is reciprocable in parallelism with the axis of the work spindle or is pivotable about an axis which is parallel to the axis of the work spindle. Such first carriage supports a second support which is movable thereon substantially or exactly at right angles to a line extending radially from the work spindle and in the general direction of the second support. A cross-slide is mounted in the second support for movement radially of the work spindle and can be shifted by a piston which is reciprocable in the housing of the second support.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
127 words
In a machine tool, particularly in a turning lathe, a combination comprising a frame member; a work spindle rotatably mounted in said frame member; a first support mounted on said frame member; a second support mounted on said first support for movement in a first plane normal to the axis of said spindle, said second support being movable along a straight path in said plane substantially at right angles to a line extending radially from said spindle in the general direction of said second support; a cross-slide mounted on said second support for movement in a second plane normal to said first plane, said cross-slide being movable along a straight path substantially radially of said spindle; and means for moving said cross-slide relative to said second support.
Claim 2
Dependent Claim
127 words
In a machine tool, particularly in a turning lathe, a combination comprising a frame member; a work spindle rotatably mounted in said frame member; a first support mounted on said frame member; a second support mounted on said first support for movement in a first plane normal to the axis of said spindle, said second support being movable along a straight path in said plane substantially at right angles to a line extending radially from said spindle in the general direction of said second support; a cross-slide mounted on said second support for movement in a second plane normal to said first plane, said cross-slide being movable along a straight path substantially radially of said spindle; and means for moving said cross-slide relative to said second support.
Claim 3
Dependent Claim
28 words
A combination as defined in claim 1, wherein said first support is movable with reference to said frame in substantial parallelism with the axis of said work spindle.
Claim 4
Dependent Claim
28 words
A combination as defined in claim 1, wherein said second support is movable with reference to said first support in parallelism with the axis of said work spindle.
Claim 5
Dependent Claim
26 words
A combination as defined in claim 1, wherein said second support is reciprocable with reference to said first support exactly at right angles to said line.
Claim 6
Dependent Claim
34 words
A combination as defined in claim 1 wherein said second support and said first support are pivotable on said frame member about an axis which is parallel to the axis of said work spindle.
Claim 7
Dependent Claim
25 words
A combination as defined in claim 1, further comprising means for fixing said cross-slide in a predetermined angular position with reference to said second support.
Claim 8
Dependent Claim
44 words
A combination as defined in claim 1, wherein said work spindle has a substantially horizontal axis and wherein said frame member has a surface provided with a T-groove extending in parallelism with said horizontal axis and reciprocably receiving a portion of said first support.
Claim 9
Dependent Claim
73 words
A combination as defined in claim 1, wherein said second support comprises a cylinder, a piston rod reciprocable in said cylinder substantially radially of said work spindle and having a tubular front end portion engaging with a tubular rear poRtion of said cross-slide, said cross-slide further having a tool-engaging head outwardly adjacent to said rear portion and an external conical centering surface engaging a complementary internal conical centering surface on said piston rod.
Claim 10
Dependent Claim
78 words
A combination as defined in claim 6, wherein said second support comprises a hollow piston rod reciprocable substantially radially of said work spindle and accommodating a tubular rear portion of said cross-slide, said piston rod having an internal surface and said cross-slide having an external surface and said fixing means comprising a plurality of angularly spaced recesses provided in one of said surfaces and a projection provided on the other surface and extending into one of said recesses.
Claim 11
Dependent Claim
122 words
A combination as defined in claim 1, wherein said first support is reciprocable in parallelism with the axis of said work spindle and wherein said second support is reciprocable on said first support at right angles to the direction of reciprocation of said first support, and further comprising an additional first support supported by said frame member for pivotal movement about an axis which is parallel to the axis of said spindle, an additional second support reciprocably supported by said additional first support for movement in parallelism with the axis of said spindle, a second cross-slide movable in said additional second support substantially radially of said work spindle, and means for reciprocating said second cross-slide with reference to said additional second support.
