DEFINITION

Classification: 280/414.5

(under subclass 400) Devices comprising a leading propelling vehicle and a trailing vehicle having at least one ground wheel, the wheel being vertically adjustable with respect to the trailing vehicle frame (i.e., running gear) by means of an actuator.

(1) Note. The actuator may comprise a servomotor or an attendant manipulated lever, gear or the like which provides mechanical advantage.

(2) Note. The patents in this subclass may also involve a concurrent vertical adjustment of the draft member with respect to the vehicle frame.

(3) Note. This definition does not include apparatus in which the frame or running gear is rocked about the wheel axis, without any other relative vertical movement of the axis with respect to the vehicle frame. For such subject matter for manipulating an earth working apparatus see the search notes below.

(4) Note. This definition is not intended to include a retractable landing gear for a semitrailer. The definition also does not include a draft connection between articulated

vehicles with a retractable ground support. The definition also does not include a wheeled draft connection. See the search notes below for such devices.
