Abstract
Abstract A member mounted for limited rotation having a conduit coaxially connected to the member for directing a stream of air to the member, which stream is deflected radially outwardly and tangentially away from the member to cause rotation in a first direction, a spring connected to said member for biasing the member toward a quiescent position, and a device affixed to the member for actuating remote apparatus upon a predetermined amount of rotation of said member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
Apparatus for providing switching action including a member mounted for limited rotation about an axis in communication with means including a conduit with a longitudinal dimension extending along the axis for receiving a stream of fluid flowing in the longitudinal direction, means affixed to said member in fluid receiving communication with said conduit for receiving the fluid from said conduit and directing the fluid radially outwardly from the rotational axis and in a generally tangential direction to said member to cause rotation of said member in a first direction, biasing means connected to said member for biasing the rotation of said member in an opposite direction to the first direction and toward a quiescent position, and actuating means connected to said member for actuating remote apparatus upon a predetermined amount of rotation of said member.
Claim 2
Dependent Claim
135 words
Apparatus for providing switching action including a member mounted for limited rotation about an axis in communication with means including a conduit with a longitudinal dimension extending along the axis for receiving a stream of fluid flowing in the longitudinal direction, means affixed to said member in fluid receiving communication with said conduit for receiving the fluid from said conduit and directing the fluid radially outwardly from the rotational axis and in a generally tangential direction to said member to cause rotation of said member in a first direction, biasing means connected to said member for biasing the rotation of said member in an opposite direction to the first direction and toward a quiescent position, and actuating means connected to said member for actuating remote apparatus upon a predetermined amount of rotation of said member.
Claim 3
Dependent Claim
35 words
Apparatus as claimed in claim 1 wherein the fluid is a medium suspending a vehicle on which the velocity switch is mounted and the predetermined amount of rotation indicates a predetermined velocity of the device.
Claim 4
Dependent Claim
158 words
Apparatus for providing switching action comprising: (a) a member mounted for limited rotation about an axis; (b) fluid inlet means connected to said member for supplying a stream of fluid thereto generally along the axis thereof; (c) generally radical passageway means in said member and in communication with the stream of fluid for directing the stream of fluid generally radially outwardly from the axis of said member; (d) spring means connected to said member for limiting the rotation thereof and biasing said member in a first direction; (e) fluid diverting means affixed to said member adjacent the outer periphery thereof and in communication with said passageway means for diverting fluid exiting from said passageway means generally tangentially to the periphery of said member to cause rotation of said member in a direction opposite to the first direction; and (f) actuating means connected to said member for actuating remote apparatus upon a predetermined amount of rotation of said member.
Claim 5
Dependent Claim
158 words
Apparatus for providing switching action comprising: (a) a member mounted for limited rotation about an axis; (b) fluid inlet means connected to said member for supplying a stream of fluid thereto generally along the axis thereof; (c) generally radical passageway means in said member and in communication with the stream of fluid for directing the stream of fluid generally radially outwardly from the axis of said member; (d) spring means connected to said member for limiting the rotation thereof and biasing said member in a first direction; (e) fluid diverting means affixed to said member adjacent the outer periphery thereof and in communication with said passageway means for diverting fluid exiting from said passageway means generally tangentially to the periphery of said member to cause rotation of said member in a direction opposite to the first direction; and (f) actuating means connected to said member for actuating remote apparatus upon a predetermined amount of rotation of said member.
