Filed: 1921-02-21
Abstract: 159,218. Pateras Pescara, Raul, Marquis of. Feb. 21, 1920, [Convention date]. Screw propellers.-A helicopter comprises a car supported from a central vertical column on which turn two lifting-propellers geared to rotate in opposite directions, the central column containing actuating-mechanism for simultaneously altering the pitch of the propellers in the same or opposite senses, and for effecting a cyclic variation of pitch so as to displace the line of thrust when necesary. The blades of both propellers may be set at a negative angle of incidence for rotative gliding. Fig. 2 shows a section through the central column and the hubs of the lifting- propellers. The hubs 24, 25 are mounted on ball bearings 26, 27, 28, 29 on the column 21 and carry ball bearings 33, 34 for shafts 31, 32, on which the blades are mounted. The hubs are geared together by bevel wheels 30. A lever 35 having a handle 38 and handwheel 39 is universally mounted at 41 in a screwed sleeve 41 and has spherical seatings 42, 43 for spiders 44, 45 passing through slots in the column 21. The spiders support through ball bearings 36, 37 two rings to which links 46, 47 are pivoted, the outer ends of the links being connected to loose collars 50, 51 on sleeves 48, 49 which have quick-pitch threads engaging sleeves 52, 53 and are splined to the shafts 31, 32. The sleeves 52, 53 can slide without rotation in bearings 65, 66 and are connected by oppositely disposed links 63, 64 to rings on bail bearings carried by sliding members 61, 62 within the column 21. The members 61, 62 are connected by rods 58, 59 to a lever 56. Movement of the lever 56 causes the links 63, 64 to move the sleeves 52, 53 in opposite directions and effect opposite rotations of the propeller blades so as to vary the reactive torque when it is desired to turn the car. A swinging movement of the lever 35 sets over the ball races 36, 37 into an eccentric position so that the sleeves 48, 39 are pushed in and out of the sleeves 52, 53 and effect a periodic feathering of the shafts 31, 32. Sufficient lateral play is provided for the links 46, 47 to accommodate themselves to the eccentric paths of the opposite ends. Rotation of the shaft 85 causes the sleeve 41 to rise or fall and the links 46, 47 effect a simultaneous movement of the sleeves 48, 49 in the same direction.

Title: Improvements relating to methods of and apparatus for adjusting the pitch of corrugations in corrugated wire
IPC: B21F43/00
Filed: 1948-02-27
Abstract: 649,827. Corrugating. HARRIS LEBUS, Ltd. Feb. 27, 1948, No. 6196. Convention date, March 12, 1943. [Class 83 (iv)] In a machine for equalizing the pitch of corrugated wire 82, Fig. 11, a toothed wheel 11 feeding the work engages each transverse portion 84 of the wire in turn while a stop 49 intermittently engages the adjoining transverse portion and releases-it when the required relative displacement has taken place. The toothed wheel 11, Fig. 4, and a stop-operating cam 15, Fig. 7, having the same number of cam projections 16 as teeth on the wheel 11 are rigidly fixed on a shaft 10 which rotates in bearings on the lower machine frame 3. The frame 3 also carries a lever 17 having a rotary pin 20 bearing on the cam 15 and thereby moved in timed relation with the teeth to operate the stop 49. An open frame 27 pivoted at 30 to the lower frame 3 and clamped thereon by an arm 59 and wing nut 65 carries a longitudinally sliding frame 32 between its sides 28, the latter frame being adjustably positioned by a screw 40 threadedly engaging a block 42 thereon and rotated in a stationary L-shaped cross-member 31 on the frame 27 by a hand wheel 39 through bevel gears 35, 36. The stop 49 pinned at 55 in a bore 54 on a U- shaped frame 51 pivoted at 53 at the ends of its arms 50 to the sliding frame 32 is yieldingly forced downwards by a spring 57 in a socket 58 under the cross-member 31. A channel 47 in the lower faces of the frames 27, 31 backed by a hardened plate 44 forms a passage for the corrugated wire through the machine. As the wire is fed through the machine by the wheel 11 the stop 49 prevents movement of the preceding loop until it is raised by the cam 15, whereby each loop is compressed in turn to a predetermined dimension. The longitudinal position of the stop may be adjusted by the hand wheel 39 until the required degree of closure has been given to the corrugations. In a modification in which the machine increases the length of the corrugations the stop 49 is arranged on the opposite side of the wheel 11 so that a stretch is given to each corrugation in turn. The machine may be attached directly to a wire corrugating machine and the shaft may be driven directly from the machine drive through a wheel with an adjustable gear ring to ensure proper timing between the two machines.

Abstract: 115,826. Hodgson, A. S. April 17, 1918. Spray carburettors.-In a floatless carburettor, the supply of heated fuel to a multiple-jet sprayer is controlled by engine suction, a regulated air supply enters at right-angled to the fuel jets, petrol may be used for starting, and the various adjustments and. initial flooding may be effected by means of a single control. Fuel is admitted to a chamber A having a cylindrical extension a<3>, in which fits a movable plunger E having a series of longitudinal grooves e<1> of unequal length, for spraying the fuel. The plunger carries an opentopped annular casing F with circumferential air ports f<1> registering with ports g<1> in a fixed casing G, which communicates at the upper end h<6> with the induction pipe. The ports g<1> are regulated by a rotatable sleeve K having corresponding ports k<1> and connected by a pin k<2> to a slotted arm k<3> mounted on a disk R, which is rotated by means of a control lever r<2> and a pinion r<1> gearing with teeth on the disk. The casing F and plunger E are carried by a stem e and are lifted by suction against the action of a spring b<5>. The lift due to suction is limited by a stop p<1> carried by a rod P, which is depressed by a spring p<2> and lifted by a cam p<3> on the disk R. The mixture is heated by exhaust passing through two cross-tubes h<1> of triangular section, with a central conical opening H through which the mixture passes. Heated fuel is supplied under pressure by a pipe C passing through the exhaust conduit h<4>, and is controlled by a spring-pressed check valve D and a valve B the stem of which bears against the end of the stem c of the suctioncontrolled plunger E. Petrol may be supplied at starting to a nozzle q<3> by a cock Q, on the stem of which the control r<2> is mounted. In order to flood the carburettor at starting, the casing F is lifted by means of a ring m<2> on a rod M actuated by a cam m<3> on the disk R.
