Abstract: 1,103,364. Shuttlecock skirt. CARLTON TYRE SAVING CO. Ltd. 21 Nov., 1966 [4 Oct., 1966], No. 44159/66. Heading A6S. A shuttlecock comprises striking cap 3 coupled to the narrower end of the moulded flared skirt structure whose wider end has an undulating outline seen from planes perpendicular to the axis of the skirt, each undulation having respectively first and second surfaces C and D inclined in opposite senses with respect to the axis, the first surface C containing a greater area of moulded material than the second axis. The moulded material may consist of a plurality of stems 1 lying at the outermost (as in Figure 1) or the innermost extremities of the undulations and interconnected by thin vane material which may comprise ribs and bars 10 and 11, including midstems 9. The depth of the undulations may be greater at the wider end of the skirt structure. degenerating to zero at the narrower end. The heavier first surface may be achieved by having more interconnecting ribs and bars than the second surface, or by making only the first surface continuous, and/or by providing the first surface with a projection 12 beyond the second surface. This uneven distribution of material and the undulations of Figure 1 impart a counter-clockwise spin to the shuttlecock when struck, the speed of which can be varied by varying the relative amounts of material in the first and second surface or the depth of the undulations. If the direction of the undulations is reversed, so that the first and second surfaces are interchanged, the spin will be clockwise. The lightness of the shuttlecock means that additional weighting means 13 can be incorporated within the striking cap so that the centre of gravity of the shuttlecock is at its narrower end.

In the neutral position shown, fluid returns to the tank 13 through, a line 19. To extend the rod 38, the valve 15 is moved to position 18, so that fluid from chamber 24 can return to the tank 13 through lines 22, 19 whilst fluid enters chamber 25 through lines 31, 26 and the reducing valve 10. Surplus fluid returns to the tank. A load 39 assists extension of the rod 38. In the absence of a load 39 the rod will be extended because of the difference in area of the two sides of the piston 23. To retract the rod 38, the valve 15 is moved to position 17. The return to tank is cut off so pressure builds up to a value higher than that at which the reducing valve is set so that spool 35 closes the path between ports 29, 27. Pressure continues to rise and fluid flows into chamber 24 retracting the rod 38. Fluid from chamber 25 flows through line 26 and ports 27, 32 of valve 10 to the tank 13, spool 35 can assume a relief position in which a control edge 37 opens a connection to the return port 32.
