center of the arms and attached to the main shaft of the intermediate
gear by means of a collar fixed on it. The main shaft is bored out
sufficiently deep to admit a steel rod, against which bear the three
ends of the governor arms. The steel rod presses against the
counterbalance, which is made exactly the right weight to withstand
the force tending to raise it, when the intermediate motion is running
at its designed speed. The forks between which the belt runs are also
provided with a balance weight. This brings them to the loose pulley,
unless they are fixed by means of the ratchet. Should the number of
revolutions of the intermediate increase beyond the correct amount,
the extra centrifugal force imparted to the governor balls enables
them to overcome the balance weight, and in raising this they raise
the arm. This arm striking against the ratchet detent releases the
balance weight, and the belt is at once brought on to the loose
pulley.

[Illustration: IMPROVED CREAM SEPARATOR. Fig. 3.]

The steel drum is fitted with an internal ring at the bottom (see Fig.
2), into which the milk flows, and from which it is delivered, by
three apertures, to the periphery of the drum, thus preventing the
milk from striking against the cone of the drum, and from mixing with
the cream which has already been separated. The upper part of the drum
is fitted with an annular flange, about 1½ in. from the top, reaching
to within one-sixteenth of an inch of the periphery. After the
separation of the skim milk from the cream, the former passes behind
and above this flange through the aperture, B, and is removed by means
of the tube, D, furnished with a steel tip projecting from the cover
of the machine into the space between the top of the drum and the
annular flange, a similar tube, F, reaching below this flange,
