The invention relates to an axial-flow compressor turbine in which blades are mounted in a circumferentially-extending groove formed in the stator or casing by means of dovetail or like blade roots engaging the corresponding- shaped circumferential groove. A number of retaining pins extend through holes in an end face of the casing and across the blade-retaining groove, the pins engaging grooves on the blade roots whereby the blades are located against circumferential movement. In the axial flow compressor shown, a row of stator blades 16 have root portions 18 which are engaged in an undercut circumferential groove 19 formed in the stator casing 17, the casing being in two semi-cylindrical halves. Axially-extending holes 34 are formed in the casing from the end face 26, the pitch circle of the holes lying approximately on the surface of the bottom of the blade-retaining groove 19 so that slots 28 of approximately semi-circular section are formed in the casing beneath the blade-retaining groove. The blade root portions 18 of a certain number of the blades are formed with corresponding semi-circular slots 30 so that when the blades are mounted in the groove the slots in the casing co-operate with those in the blade roots to form circular continuations of the holes 34 in the casing. The portion of each hole 34 adjacent the end face 26 is enlarged to form a recess 29 and pins 31 having heads 32 are engaged in the holes 34. The pins are secured in position by the adjacent structure 11. The intermediate portion 18a of each blade root is cut away so that the semi-circular slot 30 in the blade root is in the two end portions of the root.

A haymaking implement comprises a frame 1 supporting two arrays of raking tools 41, 35A of different types, the implement having a first working position in which both arrays work the crop in sequence and a second position in which the first array 41 alone works the crop, the second array being retained in an inoperative setting, or removed altogether. In a first construction (Fig. 1) a U-shaped part of the frame carries the first array, a series of rake-wheels 41. The second array comprises tines 37 on a driven shaft 35 carried by a frame 23, 25, 29 vertically adjustable in bearings 20, 21, 22 at the rear of the main frame 1, the shaft 35 being driven from the tractor through stub-shaft 48 and belts 46, 43 and being lockable in a raised, inoperative, position by a locking sector 52 and pin 54. The machine is mounted on three wheels 3, 4, 5 two of which are lockable swivel-wheels, and the third is a castor. In the first working position the device is drawn in the direction I by a drawbar 11 which is then attached to an arm 16 rigid with the swivel axle of the wheel 4. In this working position the rake-wheels 41 ted the crop and the spring tines 37 complete the tedding and spread the crop. In the second working position the drawbar occupies the position shown and the device is drawn in the direction III, the array 35A being raised; the rake-wheels 41 simply act as a side-delivery rake. In Fig. 3 the spring tines 75 are carried on a shaft 74 driven by a flexible drive 85 passing through the main frame-beam 61 and being connected by a telescopic, jointed, shaft 87 to the tractor. In this construction the second array is not raisable, but the tines can be set so as not to contact the ground. The rake-wheels 70 are movable into dotted positions 70a, for tedding. In Figs 5 and 6 the rake-wheels are carried on pendant arms 113 and are adjustable about vertical axes. The frame-part 111 which carries them is floatingly mounted, against the action of a spring 156, on the remainder of the frame 101 and can be locked in a raised position for transport (Fig. 9, not shown). The shaft 120 carrying the array 119 can be removed entirely, together with the mounting brackets 123, 124 in the second working arrangement. The first and second working arrangements correspond to traction in the directions 167, 170 respectively. In a modification (not illustrated) the spring-tine array may be driven from a ground-wheel or from a separate motor mounted on the implement. Specification 946,572 is referred to.

Abstract: 384,625. Sewing-machines. FAIRWEATHER, W. C., 65, Chancery Lane, London.-(Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) Jan. 12, 1932, No. 25331. [Class 112.] Chain-stitching.-The wide gauge multiple looper mechanism of Specifications 7903/14 and 216,778, [both in Class 112, Sewing &c.], are modified so that the looper has an adjustable connection with the looper-carrier to permit bodily shift of the looper in a direction normal to the needle when the looper at the end of its stroke is ready to begin its advance to seize a needle-loop. Co-operating with each needle 7 is a looper 8 the blade of which is disposed transversely of the line of feed. The loopseizing and shedding movements of the looper are across the line of feed. The needle-avoiding movements are in the line of feed. The shanks 81 of the loopers are mounted in clamps 9 at the upper ends of the twin looper-carrier levers 10. These have bearing spindles 11 in apertures in the bearing block 13. The looper levers are pivotally connected together at their lower ends by a yoke 14 which has a central bearing for the pin 15. The head 16 of this is split and is clamped to the sleeve 17 of a pin 18 received in a guide aperture of the block 13. The main shaft 6 is formed with the usual crank 19 to work the sleeve 17 to rock the looper carriers. The axis a-a of the pin 21 intersects the axis b-b of the inclined crank 19 at a point 22 which is spaced from the point of intersection 23 of the axis b-b and the axis c-c of the main shaft 6, Fig. 14. This spacing imparts side throw to the pin 21 and gives the loopers their needle-avoiding movement. The loopers are adjusted relative to the needles by moving them in their clamps 9 and rocking them on the shanks 8<1>. They are brought to accessible position for adjustment by turning the nut 29 to cause the block 13 to turn about the main shaft.

Title: Improvements in or relating to automatic steering devices for vehicles, in particular aircraft
IPC: G05D1/08
Filed: 1937-09-20
Abstract: 490,572. Fluid-pressure servomotorcontrol systems. SIEMENS APPARATE UND MASCHINEN GES. Sept. 20, 1937, No. 25488. Convention date, Sept. 18, 1936. [Class 135] In automatic steering devices for vehicles, especially aircraft, in which the rudder or other steering member 20 is adjusted by a pneumatic or hydraulic servomotor 17 provided with return or follow - up mechanism 15, a pressure responsive member 22 which is subject to a pressure differential dependent upon the control force is interposed between the servomotor 17 and the mechanism 15. As shown, a floating lever 15 is linked to a control valve 16 and to a further floating lever 12 connected at one end to a gyroscopic turn indicator 2 and at the other end to a rotary magnet 10 connected to contacts 7, 8, 9 on a compass 1. The lever 15, instead of being directly connected to the piston-rod 19 so that the inclination of the rudder or the travel of the servomotor bears a linear relation to the steering impulse or the travel of the end of the lever 15, is connected to a piston 22 normally centralized by springs 23, 24 which may be inside or outside the cylinder 21. The deflection of the rudder is thereby increased so as to produce the necessary moment for righting the craft after the deviation which produced this rudder deflection. This is shown graphically in the Specification. The compass housing 6 is adjusted by a worm 5 on a shaft 4 which also operates an indicator 3. The piston and cylinder 22, 21 may be replaced by a bellows subject to the differential pressure on its opposite sides. An isodromic device consisting of a dashpot piston and cylinder may be interposed between the piston 22 and the lever 15. The resultant pressure acting on the piston 22 may alternatively be converted into an electrical valve for controlling the valve 16.
