Abstract: 798,866. Vehicle power steering. CLEVELAND PNEUMATIC TOOL CO. May 28, 1956, No. 16491/56. Class 79(5) [Also in Group XXXIII] A steering mechanism comprises a fixed element and a rotatable element mounted thereon for rotation about a first axis, fluid actuated piston and cylinder members, and a mounting portion on each member extending therefrom generally in the same direction, one mounting portion being pivoted to one element about a second axis, and the other portion being pivoted to the other element about a third axis, the second and third axes being parallel to and equidistant from the first. Twin ground wheels 13 are mounted at the foot of an inner cylinder (not shown) which forms a telescopic shock absorber with an outer cylinder 12. A collar 14 is rotatably mounted on cylinder 12, and is attached to the inner cylinder by a scissors linkage 17, whereby rotation of the collar turns the wheel. A mounting portion 39 on the cylinder of a hydraulic jack 20 is pivoted on an axis 42<SP>1</SP> to a lug 41 on the cylinder 12, and the piston rod 27 is pivoted on an axis 44<SP>1</SP> to a lug 43 on the collar 14, whereby actuation of the jack rotates the collar. At some point in the steering range, the axes 42<SP>1</SP> and 44<SP>1</SP> coincide. In the example described, this occurs in the neutral position of the wheel. To prevent the jack from swinging freely about these coincident axes, a link 46 is pivoted at 47 to a lug 45 on the jack, and a pin 48 on the link works in a slot 49 in a lug 51 formed on the fixed cylinder 12. Successive positions of the jack and link are shown in Fig. 7, and in the neutral position where the axes 42<SP>1</SP> and 44<SP>1</SP> coincide, the slot 49 is at right angles to the line joining pivots 47 and 48, whereby the link holds the jack in position. The slot is preferably arcuate with a centre at pivot 47 when the pivot is in the position shown in full lines. In any other position of the mechanism, the pin 48 takes up a position in the slot 49 such as to relieve any bending strain in the jack. Co-operating abutments are formed on cylinder 12 and collar 14 to limit the steering range.

Abstract: 361,984. Determining courses of aircraft &c. BARR & STROUD, Ltd. and FRENCH, J. W., Caxton Street, Anniesland, Glasgow. June 25, 1927, No. 16935. [Class 97 (i).] Apparatus for determining the relationship between corresponding actual and apparent courses of an aircraft or other object in space comprises two elements whose angular positions about their centres of rotation represent the real and apparent courses, these elements being displaceable in two directions at right-angles to each other, the displacements in the direction representing the normal to the line of sight being equal, while the displacements in the other direction are in the ratio Sin alpha: 1, a being the angle of sight. In Fig. 1, if an observer at A views a target at 2 which is moving in the plane 3, 4, it appears to move in the plane 5, 6 inclined at the angle alpha to the plane 3, 4. In Fig. 2, if 2, 10 represents the actual course in the plane 3, 4 the apparent course will be represented by the line 2, 9, the point 9 lying on an ellipse 5, 7, 6, 8 which is the projection on the plane 5, 6 of a circle 3, 7, 4, 8 in the plane 3, 4. If a, b are the axes of the ellipse, then b/a = Sin a, and if y, y<1> are the ordinates of the points 10, 9 respectively, then y<1>/y = b/a = Sin alpha. These relationships are utilized in the apparatus shown in Figs. 6 and 7, comprising arms 2, 9; 2, 10 rotatable about a fixed axis 2. The pin 10 engages a link 17, 18 mounted on flexible tapes 19, 20 driven by sprockets 21, 22 on a common shaft 51 so that the link is constrained to move in a constant direction. The pin 10 also engages in a link 23, 24 similarly constrained to move in a direction at right-angles to that of the link 17, 18. The pin 9 engages in the link 23, 24 and in a link 39, 40 which is mounted on tapes 41, 42 so as always to be parallel with the link 17, 18. A pin 30 on the link 17, 18 engages in a slotted arm 31, 32, which is pivoted at its end 32 and is engaged also by a pin 38 on a slider 33 carried by a nut 34 non-rotatably mounted on a screw 35 of varying pitch. The pitch of the screw varies in accordance with values of Sin a, the point 32 corresponding to Sin 0‹ = 0 and the point 46 to Sin 90‹ = 1. With this arrangement the distance 2, 9 is always equal to 2, 10 Sin alpha. The arm 2, 10 indicating the actual course may be set by hand or by the training gear, or by dual control through a differential gear.
