than the radius of float bore 56 to limit the longitudinal movement of the float 54 downward along the shaft 32 the float stop 59 serves to maintain the float 54 on the shaft 32 during both storage and shipping of the dual flush components as well as after installation referring again to fig1 first linkage 60 connects the short flush trip arm 25 to hole 44 along a nearly vertical connection line similarly second linkage 61 connects the long flush trip arm 24 to the hole 46 along a relatively less vertical connection line the different orientation of the connection lines and location of the flush holes 44 46 produce different cam 40 motion upon activation in a manner to be described below referring now to fig1 and 4 prior to activation of either handle 27 28 the cam 40 can rest in a lateral position with its flat edge 62 in contact with the upper surface 63 of the follower 49 in this position the float 54 and follower 49 are disposed at the upper end 33 of the shaft 32 and the flapper valve 19 is seated on the valve seat 20 in a closed position the float 54 exerts a slight upward pressure on the cam 40 and thus maintains the cam 40 in its lateral position referring next to fig1 and 5 upon activation of the.
