Title: Single control with reflex action for "helicopter" type flying apparatus
IPC: B64C27/54
Filed: 1930-12-02
Abstract: 360,229. Helicopter controls. PESCARA, R. P., 22, Plaza de Cataluna, Barcelona, Spain. Dec. 2, 1930, No. 36349. Convention date, Dec. 30, 1929. [Classes 4 and 114.] A helicopter having two oppositely-rotating, coaxially arranged lifting screws of variable pitch is fitted with a single control device for effecting (a) a simultaneous variation of pitch of all the blades for effecting ascent, descent and hovering, (b) an excentring of the thrust for tilting the machine in any direction by a cyclical variation of pitch of all the blades, and (c) a variation of pitch of one screw relative to the other to cause the machine to turn in azimuth. The movements of the control are arranged to be in instinctive directions.. Within the hollow shaft 10 of the upper lifting screw is a member 45 having projections 46 sliding in slots in the shaft. The lower end of the member 45 has a ball 41 on which, is tiltably mounted a member 40, projections 42 on the ball engaging grooves in the member 40 to ensure its rotation with the shaft. The member 40 is connected by ball-jointed links 43 to cables 11 which effect the variation of pitch of the blades of both screws. The member 40 is connected by a ball race to a member 32 which is connected by trunnions to the sides of a loop 26 on a lever 25 which is supported at one end by trunnions 36 sliding in a slotted fork 37 pivoted on a fixed bracket 39. The other end of the lever 25 has a fork 24 engaging a similar fork 22 on a control lever 21 so that as the lever is raised and lowered the member 40 is raised and lowered to vary the pitch of all the blades simultaneously, and lateral tilting movements of the lever result in lateral tilting of the member 40 to effect cyclical variations of pitch. The fork 22 has an extension 27 connected to the end of a lever 30 having a forked end 34 engaging arms 31 on the member 32 so that fore and aft tilting movements of the lever 21 cause similar movements of the member 40 to effect corresponding cyclical variations of pitch. The lever 21 carries a hand-wheel 13 connected by cardan joints 14, 15 and a telescopic shaft 47, 49 to gearing 16 whereby a screwed shaft 12 extending through the shaft 10 is moved axially to vary the pitch of the lower screw independently of the upper screw. The centre of the joint 14 is on the axis of the joint between the forks 22, 24. The cables 11 are connected, as shown in Fig. 4, to a floating ring 115 by which the pitch of the blades of the upper is adjusted by cables 114, sliders 113 and links 112. The return leads of the cables 11 are connected by clamps 118 to cables 117 passed around pulleys on a member 120 connected to the rod 12, the cables 117 supporting a floating ring 125, composed of two parts connected by a ball race, by which the pitch of the blades of the lower screw is adjusted.

Title: Overrunning clutch for transfer case transmission
IPC: F16D41/22
Filed: 1971-08-03
Abstract: 1363306 Ratchet clutches ASPRO Inc 3 Aug 1971 [3 Aug 1970] 36480/71 Heading F2C A reversible over-running clutch has an output shaft 10 with collars 20 and 22 splined on it with clutch teeth 20b and 22b, respectively, these having an over-running profile and cooperating with sets of teeth 24c and 24b, respectively, on a central drive member 24 if this is moved left or right of the position shown in Fig. 14. The member 24 is held in a central drive retainer 32 splined to the driving shaft (Fig. 1, not shown) by splines having a lead angle of 30 degrees. The central drive member has additionally projections 245 extending radially inwardly which co-operate with teeth on hold-out rings 50 and 52 to prevent engagement of the clutch under normal conditions (see Fig. 12), the normal condition being with the output shaft 10 over-running the input. The rings 50 and 52 are retained by the collars 20 and 22 but are rotatable relative to them. As shown in Fig. 12, with the input and output shafts rotating in the arrowed direction the splines connecting the drive retainer 32 to the input shaft tend to move the central drive member 24 to the right of the position shown in Fig. 14, but since the output shaft 10 is rotating faster than the input the rings 52 and 50 abut the projections 24b and lands 52c prevent further movement to the right of the member 24, and so prevent teeth 24d and 22b from engaging. On the output rotating slower than the input the rings move faster than the projections 24b, and the drive member 24 is allowed to move further to the right (to the broken line position of Fig. 12), in which position the teeth 24d and 22b engage and torque can be transmitted. When the output shaft 10 again rotates faster than the input the over-running clutch disengages and the neutral position of Fig. 14 is again attained. The clutch teeth on the left of Fig. 14, and ring 50, come into play when the drive direction is reversed, the operation being the same. Brakes (46, Fig. 1, not shown) act against the retainer 32 ensuring a torque between it and the input shaft to enable it to screw along it. The device is used in a vehicle having drive to two axles, one of which rotates faster than the other (due to such as smaller wheels), so that no torque is transmitted to this axle unless slipping occurs at the other axle (normally used for drive transmission).
