DEFINITION

Classification: 239/237

(under subclass 225.1) Apparatus provided with a motor means to move the distributor, said means including a surface which is moved by the weight, pressure or impact of at least a portion of the stream of fluid in a flow conduit which, as disclosed, communicates with the outlet.

(1) Note. Motor means which operate solely in response to the reaction of a stream of fluid leaving a nozzle are excluded and will be found in the pertinent subclass herebelow.

SEE OR SEARCH THIS CLASS, SUBCLASS:

214.13, for a moving distributor caused to move by impingement of fluid directly on the distributor or on an element connected thereto.

222.15, for a distributor nozzle which is caused to continuously move by action of a rotating deflector to which the nozzle delivers fluid.

233, for moving deflectors having a non- rotary motion and which form a motor means to move a distributor.

SEE OR SEARCH CLASS 91, Motors: Expansible Chamber Type, appropriate subclasses for an expansible chamber fluid motor, per se, and for the combination of such a motor with a nominally recited distributor means in the absence of disclosed structure to discharge the motor exhaust fluid through the distributor.

418, Rotary Expansible Chamber Devices, appropriate subclasses for rotary expansible chamber motor, per se, and for the combination of such a motor with a nominally recited distributor means in the absence of disclosed structure to discharge the motor exhaust fluid through the distributor.
