Title: Rotary wing aircraft
IPC: B64C27/54
Filed: 1946-10-11
Abstract: 621,161. Helicopters. PENTECOST, H. T. Oct. 11, 1946, No. 30455. Convention date, Oct. 9, 1945. [Class 4] In a helicopter of the coaxial contra-driven rotor type, a single control member effects cyclical pitch control of the rotor blades for control in azimuth, and also impresses simul. taneous collective and differential collective pitch control on the blades for effecting altitude and yawing control, respectively, of the aircraft. As shown, the control mechanism consists of a lower gimbal 92 including two sleeves 94, 98, the former of which actuates the pitch control arms 116 of the lower rotor blades while the latter, through vertical links 106 and an upper gimbal 108, actuates the arms 116 of the upper rotor blades. The sleeves 94, 98 are connected by a helical pin-and-slot joint 156, 158, whereby relative rotary movement of the sleeves results in relative vertical movement. The pilot's control member 74 is connected to the lower gimbal by a rod 76 carrying a yoke 86, a link 136 and crank arm 138, and a link 152 attached to the outer sleeve 98. To vary the lift of the rotors the member 74 is raised or lowered vertically, the rod 76 sliding in a bush 78 mounted on a pivot pin 82, to lower or raise the yoke 86 and thus increase or decrease the blade pitch of each rotor. The pivot pin 82 may carry friction washers 80 for holding the control member 76 in its adjusted position. To impart the necessary cyclical pitch movements to the rotor blades for propulsion purposes the member 74 is moved in the appropriate direction in azimuth, the gimbals being tilted by the joint movements of the rod 76 and yoke 86, and the link 136 and crank 138 connected to the lower gimbal ring. For purposes of yaw control the collective rotor blade pitches are varied differentially by rotating the control member 74 about its axis, the link 152 thereby rotating the outer sleeve 98 to move the latter axially in relation to the inner sleeve 94.

Title: Improvements in or relating to power transmission mechanism for the propellers of boats or other vessels
IPC: B63H20/10
Filed: 1930-10-11
Abstract: 364,207. Detachable propelling installations. COOPER, F., Verulam, Hythe, Hampshire. Oct. 11, 1930, No. 30505. [Class 114.] Detachable power transmission for screw propellers for use on boats and aircraft is such that the propeller may be moved about a vertical axis for steering, and during the reverse drive is locked to its support, but during the forward drive is free to swing upwardly in a rearward direction if obstacles are encountered. A bracket 6 adapted to be attached to the transom of a boat or airship gondola carries in bearings a driving shaft 1 which couples the engine through a bevel wheel 7, a bevel wheel 8 on a cross shaft 9 and a bevel wheel 17 with a depending shaft 18 which is in turn geared to the propeller shaft 28. The depending shaft 18 is carried in a casing 21, 22 which is mounted in a support 16 so as to be rotatable by bevel wheels 20, 37 from a bevel wheel 36 on a hollow shaft 4 at the inboard end of which is a sprocket 35 or other steering mechanism. On rotation of the steering gear the whole casing rotates and in the reverse position a shoulder 41 engages with a ledge 42 whereby the mechanism is locked against movement about the axis 9. In the forward running position, however, there is no locking and should the skeg 33 encounter resistance, the depending part of the mechanism can tilt about the axis 9 and the drive connection 17, 8 remains unbroken. For the purpose of guiding the parts in this tilting operation, the upper part of the support 16 carries a part cylindrical extension 13 which slides inside a cylindrical barrel 11, 12 which is supported on the frame 6 and encloses the upper gearing. If desired a lever may be fitted so that the tilting movement of the propeller may be effected or assisted manually.
