Abstract

293,588. Turnbull, W. R. Aug. 16, 1927. Screw propellers.-The setting of the blades of a variable pitch screw propeller is indicated on an ammeter as a result of a pointer on the blade moving over a resistance coil on the boss. A spring pointer 14 on the blade 10 contacts with a resistance coil 13 on the boss 11, the resistance being in a circuit which includes an ammeter which is calibrated to give blade settings. Specification 293,587 is referred to.
