This cylinder, which constitutes the
disinfection chamber, is mounted upon wheels and is provided with
shafts, so that it can easily be hauled by a horse or mule. The
cylinder is of riveted iron plate, and is covered with a wooden
jacket. The door is provided with a flange that enters a rubber lined
groove in the cylinder, and to it are riveted wrought iron forks that
receive the nuts of hinged bolts fixed upon the cylinder. The nuts are
screwed up tight, and the flange of the door, compressing the rubber
lining, renders the joint hermetical. The door, which is hinged, is
provided with a handle, which, when the stove is closed, slides over
an inclined plane fixed to the cylinder.
The steam enters a cast iron box in the stove through a rubber tube
provided with a threaded coupling. The entrance of the steam is
regulated by a cock. The box is provided with a safety and pressure
gauge and a small pinge cock. In the interior of the stove the
entrance of the steam is masked by a large tinned copper screen, which
is situated at the upper part and preserves the objects under
treatment from drops of water of condensation. These latter fall here
and there from the screen, follow the sides of the cylinder, and
collect at the bottom, from whence they are drawn off through a cock
placed in the rear.
