DEFINITION

Classification: 172/329

(under the class definition) Apparatus comprising (1) an earth working element having a handle for manipulating and supporting it (e.g., a hand hoe) or (2) an implement having a handle whereby the device is guided or propelled by a walking attendant (e.g., a walking plow) or (3) an earth working element supported on a frame and having means such as handles or foot pedals contacted by the attendant to manipulate the earth working element, the said element being held in the position to which it is moved by continued application of force on the manipulating means by the attendant (e.g., a straddle row cultivator) or (4) earth working means harnessed to the attendant or worn by him (e.g., a glove with earth scratching prongs) or (5) manipulating means such as a handle or foot pedal for moving any part (e.g., a draft tongue) and holding it in the position to which moved by continued application of force by the attendant.

(1) Note. An earth working element which may be raised by an attendant so as to be scraped by a stationary or relatively movable cleaner is not included under this definition. See subclass 461 and subclasses 606+ for such devices.

(2) Note. A seat or attendant's station is not considered a handle or manipulating device under this definition. See subclasses 431+ for apparatus with means manipulated by moving a seat or shifting weight on a seat or other attendant's station.

(3) Note. For part (3) of this definition a broadly claimed implement about which an earth working element is manipulated is considered a mounting frame.
