Title: Aircraft including apparatus for steering a nose wheel thereof
Inventor: RENNER ECKARD
IPC: B64C25/50
Filed: 1969-12-23
Abstract: 1294479 Steering aircraft ground wheels VEREINIGTE FLUGTECHNISCHE WERKE-FOKKER GmbH 23 Dec 1969 [17 Oct 1969] 62660/69 Heading B7H An aircraft comprises apparatus for steering a nose wheel 1 thereof, the apparatus including a rudder bar 2, a device for varying the ratio of movement of the nose wheel to movement of the rudder bar and means for controlling steering forces on the nose wheel. As shown, the rudder bar 2 is connected to a bifurcated lever 4 pivoted about a bearing 8. A linkage 5 comprises a bolt 7 slidable in a slot 6 in the other arm of lever 4, the linkage being connected to a control valve 12 and a camfollower 17. The bolt 7 is connected to one end of a piston-rod of a valve 9, to which rod is also connected a lever 10 for actuating a pressure reducing valve 11 in the supply line to the valve 12. Outputs of the valve 12 are connected to steering cylinder 13 and to a limiting valve 14 also in said supply line. The steering gear comprises a rack 21 engaged by a pinion 20 with which a cam 18 is rotatable, the cam 18 and cam-follower 17 acting to feed back steering movements to the rudder bar. With the bolt 7 at the end of the slot 6, as shown, movement of the rudder bar 2 fails to produce movement in the linkage 5 and steering is not accomplished. On contact of the nose wheel with the ground a load-switch causes hydraulic fluid to be supplied to valve 9 to move the bolt 7 one step along slot 6 so that slight steering movement, e.g. up to 10 degrees, of the nose wheel is possible by actuation of the rudder bar. Simultaneously, lever 10 acts on pressure reducing valve 11 with the result that an increased pressure is thereafter applied to valve 12. Such a pressure is still, however, low enough to enable the wheel to align itself with the direction of travel of the craft on touchdown should the wheel have been steered by operation, of the rudder bar, intended to counteract the effects, on the craft, of lateral air movements. A further, manual switch can be operated to increase the actuation of valve 9 to move the bolt 7 to the other end of the slot 6 after landing, whereby the ratio of nose wheel to rudder bar movement is further increased allowing steering angles of, e.g., up to 45 degrees, to be adopted. Simultaneously valve 11 causes the full pressure of the hydraulic supply fluid to be supplied to valve 12 and hence the steering cylinder whereby steering forces are increased.

Abstract: 627,302. Ink-ribbon mechanism. ALONA AKT.-GES. July 15, 1946, Nos. 21127, 21128 and 21129. Convention dates, May 15, 1945, July 14, 1945, and July 19, 1945. [Class 100 (iv)] [Also in Group XIX] Ink ribbon 85 for the impression mechanism of a workman's time-recorder (see Group XIX) is rolled on spools 87, 88 and guided over a type mechanism housing 86 for co-operation with a hammer 89 coacting with type wheels 90. Each time the hammer swings forward to make an impression, a lever 100 is rocked so that a pawl 97 or 98 pivoted thereon advances a ratchet-wheel 95 or 96 to feed the ribbon from one spool to the other. As shown in Fig. 10, one of two arms 109 of a floating member 108 is holding up a rocking member 102 so that it engages a pin 104 to hold the pawl 97 free from the ratchet 95 against the action of a spring 101, while the other arm 109 allows similar mechanism to rest free of the pawl 98 so that its spring 101 holds it in engagement with the ratchet 96. As the diameter of the spool 88 increases, a foeler 119 turns a lever arm 111, interconnected with one of the arms 109 by a spring 1121, until the lever 111 strikes a similar lever 110, connected to the other arm 109 by a spring 112, and a pawl 113 rides on a surface 114 of the float 108, when the relative tensioning of the springs 112, 112<SP>1</SP> causes a toggle action which reverses the relative positions of the various similar parts so that the pawl 97 engages the ratchet 95 and the ribbon feeds on to the spool 87.
