.~ Scattering means has to and fro movement (e.g., vibratory, etc.)
DEFINITION
Classification: 239/659
(under subclass 650) Apparatus in which the strewing means has an oscillating, reciprocating, shaking or other back and forth movement while in operation in order to effect or assist the strewing function.
(1) Note. The movement of the strewing means may be caused either by a positive drive or by the impingement of the material onto such means so as to cause the back and forth movement due to the construction or arrangement of the means, e.g., the means is of springy material which vibrates when hit by the material.
(2) Note. The main structural difference between this subclass (659) and the vibratory subclasses of Class 222, Dispensing, subclasses 161, 196-203 is that in subclass 659 the vibrating member is sufficiently near the terminal material contact point that the vibratory movement causes the discharging material to scatter, while in Class 222 the vibration merely causes the material to move toward or out of the discharge outlet.

4, for a process of scattering or spraying a fluent material by an element which is caused to continuously vibrate.
102.1+, for a device which sprays a fluid by means of a motor driven element which cyclically and rapidly changes the normal character of discharge of fluid from an outlet (e.g., by continuously moving the discharge member, or continuously moving a member in contact with the fluid). 225.1+, for a fluid spraying or sprinkling device comprising a distributor which is continuously moving (e.g., oscillating) relative to a support during discharge.
652, for a device in which a nonfluid material is caused to be scattered or strewn by reciprocation of a tube manually by a person.
