ABSTRACT:
A new and improved wind velocity signalling apparatus includes a first wind velocity sensing and signalling assembly which is connected to a support structure (such as a gabled roof) and which senses and signals the occurrence of wind of a predetermined velocity. An alarm assembly sounds an alarm upon receiving a signal from the first wind velocity sensing and signalling assembly upon occurrence of the predetermined wind velocity. The first wind velocity sensing and signalling assembly includes a wind scoop assembly for receiving wind, a wind vane fixed onto the wind scoop assembly for directing the wind scoop assembly into the wind, and a bearing assembly connected between the wind scoop assembly and the roof. A wind velocity sensor assembly receives wind pressure from wind scooped up by the wind scoop assembly and senses a predetermined wind velocity. The wind velocity sensor assembly includes a wind-pressure-responsive member which is in communication with wind scooped up by the wind scoop assembly and which is responsive to a first force exerted by the wind pressure. A counterforce assembly exerts a predetermined counterforce on the wind-pressure-responsive member against the first force exerted by the wind pressure. An electric circuit completion assembly, connected to the counterforce assembly, signals the alarm assembly when the first force exerted by the wind pressure on the wind-pressure-responsive member exceeds the predetermined counterforce exerted by the counterforce assembly on the wind-pressure-responsive member.
