DEFINITION

Classification: 414/634

Single axis, horizontal and fixed:

(under subclass 632) Apparatus wherein all of the relative pivotable movement of the guide takes place about a single axis, which axis lies on a horizontal line and is not displaceable therefrom.

(1) Note. The movement about the axis is, therefore, swinging movement in a vertical plane.
