The device of the invention is operated as follows,
assuming the container 1 to be ?lled with a liquid such
as paint which-will settle on standing. The ratchet 13
is set by engaging the stop 20 at the desired index numeral.
This setting of the ratchet also sets the stop 23 to limit
the movement of the handle 17. Initially the handle is
moved a few strokes to ?ll or prime the chamber 4. The
liquid ?ows from the container 1 into the chamber 4
This invention relates to devices for measuring liquids,
