THE VALUE OF THE STEAM JACKET.
\R. CHARLES T. PORTER contributes
an interesting article on
the value of the steam jacket to a
recent issue of the American
Machinist. Although he has no
fresh theories to propound or new
truths to enforce with respect to
this much-debated question, he
contrives to explain some old facts
in a simple and intelligible manner
that brings them within the grasp of those whose
mathematical training does not permit them to enter the
region of thermo-dynamics, as the subject is ordinarily
treated, and for the benefit of those of our readers who
(D
come within this category, we have ventured to
reproduce it.
He says : The question is often asked by disbelievers
in the advantage of the steam jacket, and that, too,
with an air of triumph, which shows that they think it
is a hard one to answer, " How can the jacket save
steam, when, in order to prevent condensation in the
cylinder, the same weight of steam has to he condensed
in the jacket ? "
I propose to answer this question, and to show
precisely how the jacket operates to prevent loss of
steam, and how considerable a saving is effected by it.
It is important that the'understanding of this subject
he clear and definite. I shall do what I can to make
it so.
To prevent misconception on the part of anyone, it
may be first stated that a jacket has no communication
with the interior of the cylinder. The so-called jackets
