bracket and cmc apertures that would occur if a regular rivet were used a regular rivet would expand after installation to fill the hole and damage the cmc the flared end rivet functions more like a pin and secures the hardware without adding the extra stress that a traditional rivet would alternatively rivets 26 may be substituted with pins that would also function to securely connect bracket 14 to cmc 18 and hold bracket 14 in position rivets 26 may be installed inside of a plurality of optional sleeves 22 before being inserted into bracket apertures 32 and cmc apertures 20 the function of sleeve 22 is to prevent any stress or damage from being induced in the edges of cmc apertures 20 a leaf spring 16 is inserted at the point where bracket 14 and cmc piece 18 converge the purpose of leaf spring 16 is to dampen mechanical vibrations and to compensate for slack induced due to clearance between the mating parts the leaf spring 16 impinges directly upon the cmc piece and the bracket 70 see fig3 fig2 illustrates a second embodiment of the present invention generally shown by reference numeral 46 elements of the first embodiment are substantially identical to the second embodiment except where indicated the.
