The apparatus shown in the annexed cuts is capable of effecting a
certain amount of saving in the fuel of a generator, and of securing a
normal operation in a steam engine. If occasion does not occur to blow
off the motive cylinder frequently, the water that is carried over
mechanically by the steam, or that is produced through condensation in
the pipes, accumulates therein and leaks through the joints of the cocks
and valves. This is one of the causes that diminish the performance of
the motor.

[Illustration: BACHMANN'S STEAM DRIER. FIG. 1.]

The steam drier under consideration has been devised by Mr. Bachmann
for the purpose of doing away with such inconveniences. When applied to
apparatus employed in heating, for cooking, for work in a vacuum, it may
be affixed to the pipe at the very place where the steam is utilized, so
as to draw off all the water from the mixture.

As shown by the arrows in Fig 1, the steam enters through the orifice,
D, along with the water that it carries, gives up the latter at P, and
is completely dried at the exit, R. The partition, g, is so arranged
as to diminish the section of the steam pipe, in order to increase the
effect of the gravity that brings about the separation of the mixture.
The water that falls into the space, P, is exhausted either by means of
a discharge cock (Fig. 1), which gives passage to the liquid only, or
by the aid of an automatic purge-cock (Figs. 2 and 3), the locating of
which varies with the system employed. This arrangement is preferable
to the other, since it permits of expelling the water deposited in the
receptacle, P, without necessitating any attention on the part of the
engine-man.
