A datum point, _v_, and a graduated
socket, _v?_, allow the position of the stops, _s_, and consequently
the degree of expansion, to be known.
Steam is introduced into the small cylinder through the conduit, _i_,
and its passage into the large one is effected through the conduit,
_f_. The escape into the interior of the frame is effected, after
expansion, through the horizontal conduit, _h_. The pipe, H, leads
this exhaust steam to the open air.
The pipe, I, leads steam into the jacket, C?, of the large cylinder,
this latter being provided in addition with a casing of wood, C squared, so
as to completely prevent chilling.
The regulator, R, is after the Buess pattern, and is set in motion by a
belt which runs over the pulleys, _a_ and _a?_. It is mounted upon a
distributing box, R?, to which steam is led from the boiler by the
pipe, _r?_. After traversing this box, the steam enters the slide
valve box through the pipe, _r squared_, its admission thereto being
regulated by the hand-wheel, R squared, which likewise serves for stopping
the engine.
The cocks, _x_, are fixed at the base of the uprights, B, for drawing
from the frame the condensed water that has accumulated therein.
The lubricating apparatus, V, which communicates, through the tube,
_u_, with the steam port, _r?_, permits oil to be sent to the large
and small cylinders through the tubes, _u?_ and _u squared_.
Mr. Farcot has recently adapted this type of motor to the direct
running of electric machines that are required to make 400 revolutions
per minute.
