Abstract
Abstract Dividing or indexing apparatus for a machine tool, the apparatus including an inclinable rotatable plate and a frame comprising two portions, namely, a stationary portion, secured to the machine, and a portion movable with respect to the stationary portion, the movable portion carrying the rotatable plate, the frame being so arranged that its movable portion can effect a double movement, on the one hand of translation and on the other hand of rotation around a geometrical axis which is itself movable, permitting rocking movement of the plate.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
128 words
In a dividing or indexing apparatus for a machine, the combination of: a frame including a stationary portion secured to the machine and a movable portion movable relative to the stationary portion, a plate rotatably mounted on the movable portion, means for effecting movement of the movable portion relative to the stationary portion through a first movement of translation and a second movement of rotation around a movable geometrical axis and including two parallel ramps on the stationary portion, each ramp consisting of an horizontal portion merging with an inclined portion, with a free space between the ramps being partially occupied by the movable portion of the frame, and means on the movable portion bearing on the ramps for ensuring guiding of the movable portion during its displacements.
