(under the class definition) Apparatus comprising a framework having a ground support (e.g., wheels or wheel substitutes) a draft means for connecting it to a propulsion means and an actuator on the framework or draft means for moving the draft means vertically relative to the framework or laterally of the line of draft.
(1) Note. For the meaning of "actuator" see the class definition.
(2) Note. The draft means may be a tongue, and a movement of the tongue is considered a movement of the draft means.
(3) Note. Relative movement of the draft means and the frame caused merely by a relative movement of the ground support with respect to the frame (e.g., a tongue truck moved
vertically with respect to the main frame) is not included under this definition. The actuator must include force-exerting means acting between the frame and draft means. See subclasses 395+ for a ground support relatively adjustable vertically with respect to the frame.
