Patent ID: 10869457

Abstract:
A ratcheted “Pipe and Strap Operating Drive System” (PSODS) is disclosed which efficiently and accurately positions a blocker, or door mechanism, over an opening which is of similar profile and dimensions as the door mechanism. In the preferred embodiment, PSODS is used to vary the position of a poultry house ventilation blocker or door mechanism from a tightly-closed position against the opening, or when required, within a certain range of door mechanism open positions, as dictated by weather conditions or internal air quality. At least two ratcheted reels are co-axially connected to the exterior of a tubular “pipe drive.” Each reel is connected, at its core, to the first end of a strap, with the second end of the strap being connected to the door mechanism. Upon axial rotation of the pipe drive in either direction, the reels simultaneously rotate, straps move correspondingly so as to position the entire door mechanism within a desired range relative to the opening.
