USPC 416/135

USPC 416/135 is a patent subclass for devices with resilient mounts for or constraints on impellers which tend to bring it back to a predetermined position.

Nearby class tree:

• USPC 416/131 Articulated, resiliently mounted, or self-shifting impellers or working members. Apparatus comprising an impeller or working member, or a part thereof mounted (1) on a support by means of a joint or a yielding or elastic connection or (2) as to be capable of self movement due to the effect of dynamic forces thereon (e.g., rotary motion or working fluid). Mere working member composition of flexible material is not included; however, a flexible joint or connection permitting articulation or "controlled", shifting of a working member or part is included.
  • USPC 416/132 Sectional, staged or nonrigid working member. Apparatus wherein the working member comprises (1) multiple relatively movable surfaces (2) multiple separate or divergent surfaces which react with the working fluid sequentially or (3) a surface that isn't self-supporting, such as a sail.
  • USPC 416/133 Axially displaceable rotary carrier (e.g., hub) Apparatus in which a working member carrier supported on a rotary drive shaft is axially movable relative to said shaft in response to dynamic forces exerted on the member.
  • USPC 416/134 Nonmetallic resilient mounting. Apparatus wherein the impeller or working member is connected to the support means by a nonmetallic elastic element.
  • USPC 416/135 Resilient bias or mount. Apparatus wherein the impeller or working member movement is resisted by a resilient element which tends to restore the impeller or member to an original or predetermined position.
    • USPC 416/136 Rotary working member pivotable solely about radial axis, supported for rotation and movable only about a radial axis
      • USPC 416/137 Convolute spring coaxial with impeller shaft. Apparatus wherein the resilient element comprises a spiral spring coaxial with the impeller shaft.
    • USPC 416/138 With manual control means. Apparatus wherein the device includes mechanism whereby an operator may regulate the operation thereof.
  • USPC 416/139 Including weight bias means. Apparatus wherein the impeller or working member movement is either aided or resisted by a weight other than the impeller or working member itself.
  • USPC 416/140 Including movement limit stop or damping means. Apparatus wherein means is provided to limit the extent or reduce the frequency of the impeller or working member movement.
  • USPC 416/141 Plural articulation. Apparatus wherein the impeller or working member is supported for movement about plural pivots or for universal movement about one pivot. Impellers having a ball and socket mounting enabling the impeller to pivot about any axis of the mounting are included in this subclass.
