Title: Improvements in rotative-winged aircraft
IPC: B64C27/41
Filed: 1947-08-08
Abstract: 643,876. Helicopters. AUTOGIRO CO. OF AMERICA. Aug. 8, 1947, No. 21896. Convention date, May 14, 1942. [Class 4] A rotative winged aircraft incorporating a flapping rotor with offset flapping pivots is provided with a freely floating universally tiltable hub so interconnected with floating cyclic pitch-varying mechanism that with reference to the axis of a non-floating member, which may be controllably inclinable with respect to the mechanical axis of the rotor, the inclination of the hub axis and of the control axis of the cyclic pitch mechanism, defined as an axis normal to the plane containing the extremities of the blade pitch control arms, are proportional and of opposite senses in the same azimuth. The rotor driveshaft 6 is mounted in bearings 5, 8 on a fixed structure 3, 4, 7 and is rotated by an enginedriven shaft 14 and gears 12, 13 through a dog-type over-running clutch comprising toothed plates 15, 16 urged into contact by a spring 17. To provide for autorotation of the rotor the plates 15, 16 may be separated by a manually-controlled lever 18. The rotor hub 11 is supported on the upper end of the rotor shaft 6 by a universal joint 9 and each blade 19 is connected to the hub by a link 23 provided with flapping and drag pivots 24, 26 and mounted in a sleeve 25 journalled in the hub at 27 and formed with a pitch-control arm 33, Fig. 2. Each link 23 is extended by an arm 28 co-operating with a ring segment 29, Fig. 2, sandwiched between a pair of friction discs 30 backed by rubber rings 31 and secured within a housing free to tilt and rotate about a supporting ball member 32 secured to the upper end of the shaft 6. This arrangement permits unrestrained simultaneous drag movements of all the blades in the same sense whilst restraining relative drag movements. The hub 11 is provided with stub fittings 40, each radially in line with the extremity 36 of each pitch control arm 33 and attached respectively to the members 40 and 36 are control rods 39, 34, the lower ends of which are connected by a lever 35 pivoted at 38 to an extension 42 of a freely revolving ring 43. The ring is mounted on a swashplate 44 and rotated with the rotor shaft 6 by a scissors linkage 47, 48 attached thereto. The swashplate 44 is mounted on a ball member 46 free to slide on the fixed tube 7 and vertical movement of the member 46, under the action of a linkage 64, 67, effects collective blade pitch control. Cyclical pitch control is provided by a member 58 universally mounted at 61 and engaging an arm 54 depending from the swashplate 44. If, due to an external disturbance in the rotor disc, the pitch of the blade 19 as viewed in Fig. 2 is decreased, the resulting downward movement of the extremity of the arm 33 will, through the linkage 34, 35, 39 tilt the rotor hub 11 downwardly and rearwardly which will increase the pitch of the next advancing blade to restore the equilibrium of the rotor. Specification 410,532 is referred to.

Filed: 1933-08-04
Abstract: 423,246. Type-printing telegraphy. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, and HARRISON, H. H., 15, Mayville Road, Mossley Hill, both in Liverpool. Aug. 4, 1933, No. 21954. [Class 40 (iii)] In a printing-telegraph system in which the character printed is determined by a characteristic point in a fixed cycle, current flows over the line for the same length of time for each character and the point in the cycle at which a reversal of the current occurs determines the character to be printed. The depression of a character key CKL operates a member KOP to move a detent L which permits a one-revolution clutch SC to connect a shaft S2 to a constantly rotating shaft S1. A cam C2 on the shaft S2 moves the spring of contacts ONS1 to connect the line to the armature of relay TR from which a positive impulse is sent until a distributer BA reaches the segment associated with the depressed key at contacts CS through which the armature of the relay TR is reversed to transmit negative current to the line. At the receiving station the positive start impulse operates relay RR to its left-hand contact over which the start-magnet SM is energized. and the clutch RC operated to connect the shaft S3 to the shaft S for one revolution. A cam C3 moves springs of the contacts ONS2 into the energizing circuit of the printing magnet PM which is operated when relay RR moves its armature to its right-hand contact in response to the current reversal at the transmitter, and trips a lever PA to effect printing from the type-wheel TW. To eliminate current through the relay TR when the apparatus is at rest the brush normally rests on a dead segment and battery is connected to the relay TR by a divided segment engaged by the brush immediately on moving from its rest position. A locking bar LB operated by a cam C1 on the shaft S2enters slots in lugs L1 of theunoperated key levers and rests on the top of the lug of the key which has been depressed.
