Title: Turbine wheel propeller and motor
IPC: B64C11/00
Filed: 1930-10-23
Abstract: 371,803. Rotary propellers and current motors. STRANDGREN, C. B., 14, Rue Gallieni, Versailles, Seine-et-Oise, France. Oct. 23, 1930, No. 31860. Convention date, Nov. 20, 1929. Void [Published under Sect. 91 of the Acts]. [Classes 4 and 114.] A rotary propeller for aircraft &c., or a current motor, wherein blades are feathered about axes parallel to the shaft so that normals to the blades pass through a common point which is normallv fixed in relation to the shaft but can be adjusted to alter the direction of thrust, has its blades linked to pivoted members having guide members engaging followers arranged in a circle upon a rotating member which can be displaced in any direction from a position concentric with the shaft to an eccentric position. The blades are connected by parallel links 2 to members 16 pivoted at 14 on ball bearings supported by dished plates 11, 12 rotating with the propeller on a shaft O. The members 16 are slotted to engage rollers 20 arranged in a circle between plates 21, 22 connected to a hub 23. The plate 21 is connected by parallel links 26, 27 to an intermediate member 30 connected by another pair of links 33, 34 to the plate 11 so as to rotate therewith but permit of linear displacement of the hub 23 in any direction parallel to the plate 11. The hub 23 is engaged by rollers 42 carried by an annular member 41 which has slides 43, 44 engaging grooves 45, 46 on a plate 47 so that the member 41 can be displaced laterally by cables 60, 61. The plate 47 can slide vertically in guides 50, 51 on a fixed plate 52 and is connected to a cable 66. The cable 66, after passing over guide pulleys, is connected to one end of a centrally pivoted lever 79, Fig. 7, the other end of which carries a pivoted lever 64 to which the cables 60, 61 are connected. A lever 65 on the lever 64 enables the plate 47 to be moved vertically and the ring 41 to be displaced laterally across the plate 47 thereby eccentring the plates 21 and varying the direction of thrust of the propeller. Two such propellers may be mounted on opposite ends of a transverse shaft on an aircraft. To prevent excessive. angles of incidence between the blades and their flight paths, means may be provided for partially rotating the plates 21, 22 as their eccentricity is increased, or the slots in the members 16 may be curved.

Abstract: 366,084. Reversing-gearing. STUBBS, J. H. and STUBBS, Ltd., J., Mill Street Works, Ancoats, Manchester. Oct. 24, 1930, No. 31949. [Class 80 (ii).] The control lever 17 of reversing- gearing suitable for motor boats when moved out a locking notch 21 or 22 disengages the engine clutch prior to changing mesh to effect reversal. The driven member 4 of the engine clutch is loose on the driven shaft 5 and is adapted to be thrust into engagement with the other member 3 fast on the engine shaft 3a by a fork 18 on a cross shaft 15, Fig. 2. When the lever 17 is moved out of either of the locking notches 21, 22 in a fixed gate 20 corresponding to ahead and astern running respectively, the shaft 15 is rocked to disengage the engine clutch. Lateral movement of the lever 17 between the ends of the notches, which is effected by bending the lever 17, rocks a U-lever 23, which rocks a shaft 25 and through a striker 27 shifts a gear 7 so as to reverse the drive. In the position shown in Fig. 1, the gear 7 connects a gear 6 rigid with the clutch member 4 to a gear 11 of equal size fast on the shaft 5, yielding forward drive. The shifting movement causes the gear 7 to connect the gear 6 to a countershaft gear 12. The reversed drive passes from the countershaft 14 through a gear 13 constantly meshing with the gear 11.

Title: Improvements in or relating to leverage systems particularly for brakes
IPC: B60T11/224
Filed: 1927-11-30
Abstract: 307,319. Boughton, E. B. Nov. 30, 1927. Fluid-pessure.-In a hydraulic braking system in which a low pressure piston and a high pressure piston of smaller diameter are operated by a lever mechanism while the low pressure piston moves to take up play the high pressure piston is also moved and continues to move when the movement of the low pressure piston ceases when the play is taken up. The leverage is greater on the high pressure piston so that the low pressure piston is moved faster than the higher pressure piston. The lever 11, Fig. 1, operates the low pressure piston 3, Fig. 5, through a spring 17, Fig. 1, a bell-crank lever 14 and a rod 13 and the high pressure piston 4, Fig. 5, directly through a rod 10 and an extension of the lever 11. The cylinders 1, 2 containing these pistons are arranged in a casing 9 containing the operating fluid and are connected by a non-return valve 21 so that fluid can be forced through this valve, by the piston 3, to the connection 45 to the transmission system when the lever 11 is first moved. When slack has been taken up the spring 17 is compressed and the pressure in the cylinder 2 increases as its piston is directly operated, closing the valve 21 and applying pressure to the brakes. A non-return inlet valve formed by cup-washer 23 supplies fluid to the cylinder 1 on the return of its piston. Excess fluid in the system is returned to the casing 9 by openings 24 in the cylinder 4. The bell-crank lever 14 is returned to normal position by a stop 19 on the lever 11.
