Title: Novel or improved method of and means for controlling the movement of aeroplanes when landing or travelling on land
IPC: B64C25/48
Filed: 1935-01-29
Abstract: 450,771. Aircraft wheel brakes. COLBOURNE, J. H., Wear Giffard, Cliff Hill, Warwick. Jan. 29, 1935, No. 2844. [Class .4] In an aeroplane wheel brake mechanism of the kind comprising a brake pressure originating device and a differential leverage device operated by connection to the rudder bar for varying the braking pressure on the two sides of the craft, the differential leverage device is situated at one end of the system to act as a reaction anchorage, the brake pressure originating device lying functionally between the brakes proper and the differential leverage device. In one form, Fig. 5, a hand brake lever 17 carries a pair of jockey pulleys 16 around which pass cables 33, 4 connected at one end to brake levers 18 and at the other at spaced points 2, 3 respectively to a variable leverage element 1. Element 1 is fulcrumed at one end 5 of a lever 10 adapted to be rotated about pivot 11 by a connection to the pilot's rudder bar. Element 1, Figs. 1 and 2, is formed with a slot 6 curved in an arc struck from pivot 11 and is located axially between two arms 14 of lever 11 and restrained in its own plane by guide plates 7, 8 fixed to a housing 9 in which the device is enclosed. Fulcrum pin 5 may engage the sides of slot 6 by a ball bearing as shown in Fig. 2, or by rollers 19, 20, Fig. 4, disposed on eccentric pins 21, 22. The arrangement is such that when the brakes are applied by hand lever 16 with the rudder bar central, fulcrum 5 is equidistant from points 2 and 3 and equal braking is effected on both sides of the aircraft. Displacement of the rudder bar causes displacement of fulcrum 5 unbalancing the system and causing slackening of one brake and, to a lesser extent, increased application of the other. In a modified form, Fig. 6, variable leverage element 26 is fulerumed about a wheel 23 toothed on its periphery to engage at one side with a toothed rack 25 cut on element 26 and at the other with a rack 24 movable by connection with the rudder bar to move the wheel away from its mid position.
