INSTRUMENTATION AND CONTRACTION OF
sTEAM ROILERS-A REMEDY.


Mr. James Fisk, it,. has recently directed Mr..
Brooks, the experimenting Engineer of the Erie
Railroad Company, to make a careful examination
into the causes of injury and rapid destruction of
the vital parts of the motive machinery used rail-
| roads. This examination has been conducted with
great and attention with view to discover and
adopt effective remedies for the evil Mr. Brooks has
himself invented and patented plan for an i'm
proved construction Of boilers, to give more
uniform elasticity to all its parts including the over
Tapping Joints where the plates Tveted together
He has also made complete and thorough inquiry
INTO the effects resulting from the unequal expansion
and contraction produced by the unequal heating
and cooling of boilers, which he has found to be the
principal cause of the leaks, ruptures and injurious
strains which cause much Of the expense necessary
20 keep locomotives in repair
lie accepts and indorses the theory so persistenty
urged by Mr. Norman Wizard during the last ten
years, and has recommended in written report the
immediate application by the Erie Railroad Com
pany of WARDS Automatic Equalizing Device to the
locomotive boilers in use on that road
II is claimed to have been demonstrated, by nu-
merous and protracted trials, under great variety
of circumstances that this invention will infalhbly
eoualize to within very few degrees, the tempera-
ture of every part of steam boiler automatically
preventing experimenting Of steam and enabling a
locomotive to run safely with much smaller guam
tty of water and consequently with less weight
and more steam room than is possible without IT.
II ia also autboritatively asserted that it makes
saving in fuel while reducing the repair expenses
very largely, and gives greater eff iency to the
working power Of an engine In addition to this. it
il claimed to remedy and remove 1.-THE cause of de-
sructive explosions from all kinds of steam boilers
The following from The Locomotive Engineers
Journal very clearly sets forth this chief cause OF
injury to all descriptions of steam boilers, although
much more destructive to the boilers of locomotives
than 10 any others:
1.-THE force OF expansion and contraction is not fully
