Within a Few Days Develop
ments Are Looked for in
Strike Situation at Sparks
Resolutions to Federal Gov
ernnent and State.

following: The enormous strain to
which a high pressure locomotive
boiler is subjected necessitates the
utmost refinement in the proportion
and especially in the proper staying
of the component parts, and to this
end the form and arrangement of the
braces become of the utmost import
ance These braces extend from the
back head to the boiler shell and
from the front flue sheet to the she'll.
There are otlSer braces and stays in
addition to these which are in evil
dence wherever their necessity is in
dicated. Boilers in this country are
generally designed with five as the
factor of safety, in other words to
withstand five times the working
pressure to which they will be sub
| jected while in service, and all stay
bolts and other strengthening devices
are proportioned in accordance with
| this factor. 1t will thus be apprecl-
ated that the liability to explosion is
| exceedingly small 1t is, in fact, i'm
I possible for the modern carefully de-
signed boiler to so fail without pro-
nounced defect in one of the compo-
nent parts, which careful inspection
would have revealed. Therefore
| should boiler explode it shows that
the boiler has been abused and kept
in service in dangerous condition
without regard to the safety of en-
ployes and the public. Stay-bolts
Which unite the fre-boX to the outer
shell and which are made of wrought
iron generally one inch in diameter,
1 although sizes from seven-eights of
an inch to one and ope-eighth inches
are used to certain extent. After be-
ing screwed into the sheets the ends
are allowed to project about three
sixteenths of an inch; this is riveted
over both on the fre-box side and the
outer shell. These bolts, owing to
the expansion and contraction of the
boiler and other strains to which they
are subjected, very frequently break,
causing steam to escape in the cab,
thereby obscuring the vision of the
operator, and it is of the utmost i'm
portance that broken stay-bolts be
replaced promptly, as the strain
which they bore formerly is trans
mitted to the adjacent bolts, and the
area of breakage is liable to extend
!, with great rapidity, resulting in a
boiler explosion.
Fourth-That Federal inspection
should be made of all locomotives
and of all rolling stock in order to in
sure the safety of the employees and
the travelling public and to compel
the use of the safety appliances.
Assistant Superintendent Hickey
made the following statement:
"There is no truth in reports about
imperfect engines. We do not sent
them out unless in good condition.
we would hold trains first. 1t would
not do us any good to send them ou
otherwise.
"The strike condition had nothing
= to do with the INLAY engine. Th'
crown sheet got hot and dropped, du'
to low water, which is liable to occu
= at any time.
Mr.. Hickey then showed his dali.

"a hours. 1t had the following no
tations:
