DEFINITION

Classification: 239/657

(under subclass 650) Apparatus in which the supply holder is mounted on a support means so as to be movable from a first position in which the material in the holder is not readily movable out of the holder by gravity to a second position in which gravity causes or greatly assists in the movement of the material out of the holder.

(1) Note. The support means must comprise more than a wheel axle about which the supply holder may be tilted by the user of the device. Such devices are classified on other features.

(2) Note. This subclass is the locus for patents comprising tilting containers of the dump truck type, even if details of the dump mechanism are not recited.

222, Dispensing,

166, for a dispensing device comprising a container for material to be dispensed, the container mounted for tilting motion to discharge by gravity, e.g., mounted about a wheel axle so as to be tilted by the user of the device. The line between the two Classes, 222 and 239, Fluid Sprinkling, Spraying, and Diffusing is as follows: a dispensing hopper, per se, but not of the tilting type goes into Class 222, into a subclass other than 166; a dumping vehicle combined with a hopper attachment which acts as a spreader but not to spread a swath wider than the vehicle goes into Class 222, subclass 166 if claimed as a dumping vehicle and to another subclass as an original if not so claimed; a dumping vehicle disclosure and a claim to the combination of the vehicle and a hopper or spreader attachment which covers a swath wider than the vehicle will be classified in this subclass (Class 239, subclass 657).

414, Material or Article Handling, 469+, for a self-loading or unloading vehicle having a load receiving (i.e., supporting) portion which is pivotable relative to the horizontal.
