Fig. 1 shows the motor with all its parts in side elevation, the
flywheel and head rest being in section. Fig. 2 is a side view, with
the air reservoir and distribution valve in section through the line
1-2. Figs. 3 and 4 represent the same apparatus, but without support,
as where it is to be used on the table of a sewing machine, with the
crank of the motor directly fastened to the flywheel of the sewing
machine. Fig. 5 is a plan or horizontal section at the level of the
line 3-4, and Fig. 6 is a section passing through the same line, but
only including the cylinder and axis of the distributing valve. Fig. 7
is a horizontal section of the button of the cock through the line 5-6
of Fig. 3. Finally, Fig. 8 shows in detail, plan, and elevation the
arrangement of the starting valve.
[Illustration: Figs. 1 through 8 IMPROVED OSCILLATING HYDRAULIC MOTOR.]
This little motor does not show any new principle. It uses the old
oscillating cylinder, but it embraces in its construction ingenious
details which render its application very simple and very easy,
especially, as we have already said, to sewing machines.
