Abstract
An anemometer for sensing shaft speed rotation includes a series of circumferentially spaced, radially extending arms and a corresponding series of wind cups, each disposed at an outer radial end of one of the arms. Each arm terminates at its inner end in a hub sector correspondingly formed as a portion of a central hub and correspondingly includes circumferentially extending, complementary offset portions and fasteners for releasably interlocking the offset portions of overlappingly to define the common central hub. The hub-connecting portion is mounted on the anemometer shaft by connector means.
Claims14
In an anemometer having means for sensing shaft speed rotation and rotatable shaft means extending from said sensing means and provided with a distal hub-connecting portion, the improvement comprising:
- a series of circumferentially spaced, radially extending arms, a corresponding series of cup members, each said cup member disposed at an outer radial end of one of said arms, each arm terminating at its inner end in a hub sector, each said hub sector correspondingly formed to define a portion of a central hub, each said sector correspondingly including circumferentially extending, complementary offset portions, fastener means releasably interlocking said offset portions of one hub sector into overlapping relation to offset portions of next-adjacent hub sectors whereby to define said common central hub, and connecting means mounting said hub on said hub-connecting portion of said shaft means.
In an anemometer having sensor means for sensing shaft speed rotation and rotatable shaft means extending from said sensor means and terminating in a distal hub-connecting end portion, the improvement comprising:
- a series of circumferentially spaced, radially extending arms, a corresponding series of wind cup members, each said cup member disposed at an outer radial end of one of said arms, each arm terminating at its inner end in a hub sector, each said sector correspondingly including circumferentially extending, complementary upper and lower offset portions, fastener means releasably interlocking said offset portions of one hub sector into overlapping relation to offset portions of next-adjacent hub sectors whereby to define said common central hub, and connecting means mounting said hub on said hub-connecting end portion of said shaft means.
In a portable atmospheric sounding probe in which a sensor housing is provided with atmospheric sensing instruments including a tachometer for sensing wind speed via a shaft journaled for rotation in said sensor housing with one end of said shaft projecting from said housing, the improvement comprising:
- a wind cup assembly comprising a series of hemispherical wind cups, a hub sector for each wind cup including means mounting each said wind cup for outward radial extension from an associated hub sector, each hub sector including interlocking portions engageable with complementary interlocking portions of adjacent hub sectors, connecting means releasably securing said interlocking portions of said adjacent hub sectors together so as to define a common annular hub, and said connecting means further mounting said hub on said one end of said shaft with said wind cups extending radially in a common plane from said hub.
