will be caused to exert a perpendicular pull
and there will be no lateral strain and conse-
quently no binding and friction.
Having thus described the invention what
5 is claimed is:
A counterbalancing attachment for a pump
comprising upper and lower clamps to re-
spectively engage the pump rod and the
pump casing, levers pivoted at their inner
i ends ..o the upper clamp and each composed
of two straps having their outer ends spaced
apart in parallel relation, weight blocks hav-

ing grooves to receive the spaced straps of
the levers, clamping bolts passed through
said spaced straps to adjustably secure the 15
weights upon the levers and links between
the lower clamp and the intermediate por-
tions of the levers.
In testimony whereof I hereunto affix my
signature in the presence of two witnesses. 20
