e prolonged teeth to pass.
At intermediate points, shorter teeth gear into each other to prevent passage of steam at this point.
In v a jet of steam is forced against the vanes of a wheel as they are presented in turn in a steamtight case.
Harris's rotary steam-engine.
Fig. 4473 shows two views of the Harris engine, in which the portions are attached to two hubs and run in different directions.
One axis with hollow trunnions carries the two radial arms which emit steam at their endsn the headstall to increase its freedom of motion.
It frequently passes over sheaves on the bit and returns up the cheek, so as to pull the bit up into the angle of the mouth.
