A counterbalanced hinge assembly is illustrated for a top cover 10 of machine I1 comprising a fixed frame 12 for the hinge secured to the machine and a movable frame 13 secured to the cover and pivoted to the frame 12 by a pivot pin 14. The counterbalanced hinge derives its counterbalance forces through compression of a Belleville-type spring 15 captured in the split position of an expandable/con-tractable two piece arm 16, 17 attached at one end by clevis mounting 18 to the cover and to the hinge 12, 13.
