DEFINITION

Classification: 239/677

(under subclass 672) Apparatus comprising a driven strewing means and means for varying the rate of movement of the strewing means, or of the means delivering material towards the strewing means, independently of the speed of the primary driving means for the strewing or delivering means.

(1) Note. The speed varying means must be capable of changing speed at the will of the operator while the apparatus is in motion; merely replacing one gear with another while the apparatus is at rest is not included. A means which stops the motion of the conveyor or other feeding means at a predetermined position is excluded and will be found in subclass 678, even if the conveyor or other feeding means is reversed in direction and its speed in this reverse direction increased.
