USPC 416/149

USPC 416/149 was a patent technology category for propellers (impellers) with a mobile carrier on a supporting arm.

Nearby class tree:

• USPC 416/147 Impellers or other working members in fluids with positive means for adjustment. Apparatus comprising mechanism for moving an impeller* or working member* relative to a carrier* or support* means therefor in response to motor or manual actuation, such movement being other than that occurring as a proximate result of, or to directly effect, reaction between the impeller or working member and the medium fluid. The term "impeller" comprises a working member and parts rigidly connected to it, such as a hub or drive shaft. This category excludes a limit stop or lock adjustment which only indirectly moves an impeller.
• USPC 416/148 Tiltable carrier (e.g., hub, etc.) Apparatus wherein the impeller carrier is caused to pivot a unit relative to a supporting shaft
• USPC 416/149 Shiftable carrier support. Apparatus wherein the impeller together with the carrier and support means therefor is shiftable as a unit relative to a supporting surface or device.
  • USPC 416/150 Rectilinear motion. Apparatus in which the shiftable carrier support moves along a straight line.
• For 461/151 and 461/152, see below. They are not part of this subtree.
  • USPC 416/153 Having pitch lock or adjustable stop. Devices which include a means to retain the impeller or working member in a selected position of adjustment. The retaining means must be more than or in addition to a mere static condition of the positioning mechanism. For example, a pivoted hand lever is excluded, but a detent thereon is included under this definition. Excluded under this definition is a limit stop which shuts off the motor when a predetermined position of impeller adjustment is reached.
    • USPC 416/154 Fluid motor for impeller adjustment. This subclass is indented under subclass 153. Apparatus in which the mechanism for moving the impeller or working member comprises a fluid motor.
  • USPC 416/155 Motor bodily rotatable with impeller hub or shaft. This subclass is indented under subclass 147. Apparatus wherein the impeller or working member movement is effected by a motor mounted on and rotatable with the impeller.
    • USPC 416/156 Fluid motor; motors driven by fluid.
      • USPC 416/157 Coaxial with impeller shaft. Fluid motors which share an axle with the impeller shaft and are rigidly connected to the impeller.
  • USPC 416/158 Working member mounted or housed. This subclass is indented under subclass 156. Apparatus wherein the fluid motor is mounted on or within the working member.
  • USPC 416/159 Power or manual actuator on non-rotatable part. Apparatus wherein the impeller or working member movement is effected by a power or manual actuator mounted on a part which is fixed in position relative to the impeller or working member.
    • USPC 416/160 Planetary gearing connecting rotatable and non-rotatable parts. Apparatus comprising planetary gearing between an impeller adjusting element movable with the impeller and a part which is fixed in position relative to the impeller, which part controls the movement.
    • USPC 416/161 Axially movable impeller. Apparatus wherein the power or manual actuator effects an axial movement of the impeller as a unit relative to a supporting shaft which directly drives or is driven by the impeller.
    • USPC 416/162 Having motor. Apparatus wherein the mechanism for moving the impeller or working member is actuated by a motor.
    • USPC 416/163 Adjustment rod through entire impeller shaft. Apparatus wherein the moving mechanism comprises a rod extending through the entire length of a shaft which directly drives or is driven by the impeller.
    • USPC 416/164 Reciprocating sleeve or collar on or rod in impeller shaft. This subclass is indented under subclass 159. Apparatus comprising a sleeve, collar or rod on or in a shaft which directly drives or is driven by the impeller and is reciprocated relative thereto to effect the movement.
      • USPC 416/165 Reciprocated by coaxial screw. Apparatus wherein the sleeve, collar or rod is reciprocated by a screw which is coaxial with the shaft.
      • USPC 416/166 Rack-pinion connection to working member. Apparatus wherein the adjusting movement is effected, at least in part, by a rack-pinion connection intermediate the reciprocating member and the working member. The reciprocating member may comprise either component of the rack-pinion connection.
      • USPC 416/167 Pin-slot or cam-slot connection to working member. Apparatus comprising a pin-slot, cam-slot or cam connecting means between the reciprocating member and the movable working member.
      • USPC 416/168 Link connection to working member. Apparatus comprising link connecting means between the reciprocating means and the movable working member.

• USPC 416/151 Power derived from impeller shaft. This subclass is indented under subclass 47, not 147 apparently, and its numerical location here is confusing. It covers devices whose impellers or working members are moved directly by a shaft.
  • USPC 416/152 By brake application or release. Devices whose impeller or working member is moved by response to an element which applies a resisting (braking) force. Included under this definition is an impeller provided with a differential means between the adjusting means and the drive shaft and provided with brake means to cause relative rotation of the differential means.
