The horse, like that of M. Antoninus, has an attitude of parallel motion.
This arrangement soon came to be known as Watt's "parallel motion" (fig. 10).
A clever workman invented a means of producing this effect by the application of a parallel motion.
Throughout the 19th century the term "parallel motion" was used indiscriminately to refer to any straight-line linkage.
It will be seen that the three slits can be closed or opened from the centre by a parallel motion.
The more free their writing was, the further it tended to depart from parallel motion.
Watt about this time invented his "parallel motion," and the Governor, for regulating the speed of the engine.
It will be seen that the system is somewhat similar to the parallel motion when in action.
A few of my pupils had some difficulty in playing the scales in parallel motion, but were able to play them in contrary motion.
When beam-engines were universally used for pumping, this parallel motion was of great advantage.
