IMPROVED OSCILLATING HYDRAULIC MOTOR.
The motor of MM. Schaltenbrand & Moller is adapted for use for
household purposes, where small power is required, as in driving
sewing machines.
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
