  • Suspension system hanger means formed by cold forming processes
    Patent number: 4824056
    Abstract: A hanger means having a pair of spaced apart raised portions such that, upon connection of the hanger means with a suspension system isolator means, these raised portions restrict motion of the hanger means relative to the isolator means by being spaced apart by a distance approximately equal to the width of that passageway. These two raised portions are formed by coining one end of the hanger means so as to form, as a first raised portion, a lip and upsetting another portion of the hanger means, spaced apart from that lip, to form an annular collar, as a second raised portion.
