Title: Two-pitch airscrew
IPC: B64C11/34
Filed: 1939-12-20
Abstract: 538,162. Variable pitch propeller. ALGARSSON, G. Dec. 20, 1939, No. 32613. Convention date, Jan. 16, 1939. [Class 114] In a two-pitch airscrew the blades are .mounted in a hub-casing 31 and permitted a limited rotation with respect to the mounting sleeve 17 keyed to the engine crankshaft 15. Journal blocks 54 engage with pitch levers 47 attached to the blade roots and cause the blades to change pitch as the hub casing rotates with respect to the mounting sleeve. Stop surfaces on the mounting sleeve transmit the engine torque to corresponding stop surfaces on the hub casing either directly holding the blades in low pitch or through interposed spacers, thus holding the blades in high pitch. The spacers are inserted between the stop surfaces when the speed of the aircraft is above a selected value by the pressure of an anemometric disc 68 carried in front of the hub and are extracted from between the stop surfaces by springs which overcome the pressure on the disc when the speed of the craft is below the selected value. In operation changing to high pitch is effected when the aircraft is above the critical speed by closing the engine throttle causing the rotation of the hub casing relatively to the mounting-sleeve until the stops are in engagement. The spacers which have been biassed inward since the aircraft passed the critical speed trip to their inward position. The throttle is reopened to cause the engine to drive the propeller which then rotates back to assume high pitch. The thickness of the spacers determines the difference between low and high pitch and the low pitch position may be adjustable.

A method for forming a laminate, having a number of longitudinally-extending, laterallyspaced passages extending therethrough, comprises feeding two strips of material to the gap between two circumferentially-grooved rolls, each roll 3 or 3<SP>1</SP> being formed with a number of grooves 7 or 7<SP>1</SP> separated by lands 8 or 8<SP>1</SP>, gluing or welding the strips together under pressure along the laterally spaced lines determined by corresponding pairs of lands 7 and 7<SP>1</SP>, and forming the passages between these spaced lines by causing the material to move between the grooved sections of the rolls and stationary shaping rods 5. Before being fed between the rolls, the strips may be coated or impregnated with a binding agent or welding flux, which may be synthetic resin in the form of staple length fibres, a solution, an emulsion, a dispersion or in pulverent form. The grooved rolls 3, 3<SP>1</SP> and/or the shaping rods 5 may be heated. One of the rolls may be vertically displaceable, by pneumatic or hydraulic means, relative to the other. The facing surfaces of the lands of the two rolls may be formed respectively with cavities and projections in the manner of top and bottom dies. The strips of material may be fed between further pairs of grooved rolls before rolls 3, 3<SP>1</SP>, Figs. 2 and 4 (not shown), the further rolls being either rotatable or fixed, heated or unheated. The grooves in these further pairs are shallower than those of rolls 3,3<SP>1</SP>, the grooves of successive pairs becoming progressively deeper so that the flat strips of material assume the contour shown in Fig. 3 by progressive steps. The cross-section of each shaping rod varies aloog its length to assist in this progressive shaping. The material of the strips may be synthetic. The tubular formations in the laminate are intended to serve as sheaths for tubular electrodes of lead accumulators.
