Abstract: 539,008. Making spinners for airscrew hubs. CONSTANT SPEED AIRSCREWS, Ltd., and MARSHALL, F. G. May 8, 1940, No. 8237. [Classes 83 (ii) and 83 (iv)] Riveted joints.-In making spinners for the hubs of airscrews by riveting, after forming the holes in the parts depressions are formed round the holes so as to nest with each other, the holes are then drilled to size and flat-headed rivets inserted and riveting then effected. The spinner shell may thus be riveted to the front and back plates or the parts of a built-up spinner may be riveted together. The shell a and support bare first superposed and drilled to form holes slightly less in diameter than the rivets. The shell is then removed and the holes in the part b are subjected to a pressing operation to form a depression round each rivet hole with the metal in the vicinity of the holes of full thickness. The parts are then reassembled and the depression is sunk round the holes in the shell so that they are nested together. The holes are then drilled out to the diameter of the rivets which are provided with flat heads e so that they may be received in the depressions. In riveting the metal of the stem of the rivet fills up the rivet holes and overlaps the conical projection formed at the side of the joint. The sets of depressions may be formed in the same operation or the second set may be formed at the same time as the rivet holes are drilled to size or all three operations may be combined. The parts to be riveted may be of the same metal or the part b may be steel and the part a aluminium. Three or more of the members may be riveted together in a similar manner as shown in Fig. 7.

As shown in Fig. 2, actuating relay TN1 is energized by switching on the road lights, closes contact K1 to energize the main relay TN2, and opens contact K2 to dim the brake lights connected at 54. Relay TN2 opens contacts K 3 , K 4  and so introduces resistors R 2 , R 3  into the direction indicator circuits. Relays Rel C and Rel D operate to introduce a compensating current through resistor R4. The relay TN2 operates with a slight delay so that there is an initial unreduced current in the flash generator. A thermorelay E breaks the circuit if excess current flows due to a fault. On closing a warning flasher switch (WS) all the lamps flash simultaneously at full intensity. In a modified circuit, Fig. 4 (not shown), the resistor R4 is omitted and the winding of relay TN2 is connected in a different manner so as to act as a resistance.
