An apparatus for acting upon a load comprising: base means; load arm means with a length d1 and having: a) a first end pivotally connected to said base means; and b) a second end for applying the load thereto; spring arm means with a length d2 and having: a) a third end pivotally connected by torsio

An apparatus for acting upon a load comprising: base means; load arm means with a length d1 and having: a) a first end pivotally connected to said base means; and b) a second end for applying the load thereto; spring arm means with a length d2 and having: a) a third end pivotally connected by torsion spring means to said base means a predetermined distance from said first end; and b) a fourth end slidably connected to said load arm means, whereby the load applied at said second end: a) causes said first and third ends to pivot relative to said base; b) causes said fourth end to translate along said load arm means; and c) is acted upon by a constant force provided by said apparatus.
