Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 149 words
A machine tool for generating a surface on a workpiece, comprising: a. a base, b. a first turret mounted on the base, said turret having a periphery and being rotatable about a first axis, c. a plurality of stations located on the periphery, d. a tool for generating a surface on a workpiece, said tool being carried by one of the stations on the turret, and e. a grasping means carried by one of the stations on the turret, and capable of grasping the workpiece, wherein a column is provided, which is slidably mounted on the base, and the turret is rotatably mounted on the column with its axis extending through and at a right angle to the axis of the column, and wherein the column has a longitudinal axis, and is capable of movement along and rotation about its axis, and means is provided to control column movement.
Claim 2
Dependent Claim 149 words
A machine tool for generating a surface on a workpiece, comprising: a. a base, b. a first turret mounted on the base, said turret having a periphery and being rotatable about a first axis, c. a plurality of stations located on the periphery, d. a tool for generating a surface on a workpiece, said tool being carried by one of the stations on the turret, and e. a grasping means carried by one of the stations on the turret, and capable of grasping the workpiece, wherein a column is provided, which is slidably mounted on the base, and the turret is rotatably mounted on the column with its axis extending through and at a right angle to the axis of the column, and wherein the column has a longitudinal axis, and is capable of movement along and rotation about its axis, and means is provided to control column movement.
Claim 3
Dependent Claim 20 words
A machine tool as recited in claim 1, wherein the longitudinal axis is vertical, and the first axis is horizontal.
Claim 4
Dependent Claim 21 words
A machine tool as recited in claim 1, wherein the tool and grasping means are independent and located in different stations.
Claim 5
Dependent Claim 19 words
A machine tool as recited in claim 1, wherein the column is mounted on the base through hydrostatic bearings.
Claim 6
Dependent Claim 135 words
A machine tool for generating a surface on a workpiece, comprising: a. a base, b. a first turret mounted on the base, said turret having a periphery and being rotatable about a first axis, c. a plurality of stations located on the periphery, d. a tool for generating a surface on a workpiece, said tool being carried by one of the stations on the turret, and e. a grasping means carried by one of the stations on the turret, and capable of grasping the workpiece, wherein a second turret is provided, having a periphery, stations on the periphery and a tool and a grasping means, the tool and grasping means being mounted on the stations, and the movement of the first and second turrets being such, that transfer of a workpiece between them is possible.
Claim 7
Dependent Claim 135 words
A machine tool for generating a surface on a workpiece, comprising: a. a base, b. a first turret mounted on the base, said turret having a periphery and being rotatable about a first axis, c. a plurality of stations located on the periphery, d. a tool for generating a surface on a workpiece, said tool being carried by one of the stations on the turret, and e. a grasping means carried by one of the stations on the turret, and capable of grasping the workpiece, wherein a second turret is provided, having a periphery, stations on the periphery and a tool and a grasping means, the tool and grasping means being mounted on the stations, and the movement of the first and second turrets being such, that transfer of a workpiece between them is possible.
Claim 8
Dependent Claim 31 words
A machine tool as recited in claim 5, wherein the first turret can place a workpiece in an intermediate location where it is available to the grasping means of both turrets.
Claim 9
Dependent Claim 120 words
A machine tool, comprising a. a base, b. a workpiece storage magazine located adjacent the base, c. a column mounted on the base for rotation about and sliding in the direction of a longitudinal axis, d. a turret head mounted on the column for movement therewith and for additional movement about a rotational axis passing through the said longitudinal axis of the column at a right angle thereto, e. a workhead mounted on the base adjacent the column, f. a workpiece clamp extending from the turret and movable with the turret and column to carry a workpiece from the magazine to the workhead, and g. a tool extending from the turret at a position angularly spaced from the workpiece clamp.
Claim 10
Dependent Claim 120 words
A machine tool, comprising a. a base, b. a workpiece storage magazine located adjacent the base, c. a column mounted on the base for rotation about and sliding in the direction of a longitudinal axis, d. a turret head mounted on the column for movement therewith and for additional movement about a rotational axis passing through the said longitudinal axis of the column at a right angle thereto, e. a workhead mounted on the base adjacent the column, f. a workpiece clamp extending from the turret and movable with the turret and column to carry a workpiece from the magazine to the workhead, and g. a tool extending from the turret at a position angularly spaced from the workpiece clamp.
Claim 11
Dependent Claim 25 words
A machine tool as recited in claim 7, wherein the workpiece storage magazine includes a means for bringing the workpiece sequentially to a loading position.
Claim 12
Dependent Claim 54 words
A machine tool as recited in claim 8, wherein the said longitudinal axis of the column is vertical, the rotational axis of the turret is horizontal, a workpiece in the said loading position is horizontal, and the workpiece clamp extends in a generally-horizontal direction when it engages the workpiece in the said loading position.
Claim 13
Dependent Claim 35 words
A machine tool as recited in claim 9, wherein the workhead is rotatable about a vertical axis and the workpiece clamp extends in a generally-vertical downward direction when it delivers a workpiece to the workhead.
