steam Escape and that adequate and certain provision is
made Pr an ample supply Of water to feed the boilers at
all tines whether such vessel is in motion not SO that
in high boilers the water shall not be less than
four gches above the ue: Provided hopeU in steamers
hereafter supplied with hghpressure boilers, II the
alloy uses the outer boilers pressure of ten pounds
exceeding the working pressure allowed and at twenty
pounds above said pressure the inner boilers 1t shall
be sufficient compliance with this act.
Third. That in subjecting to the hydrostatic test
Aforesaid boilers called and usually known under the
designation Of hghpressure boilers, the inspectors shall
assume one hundred and ten pounds to the square inch
the maximum pressure allowable working power
for pew boiler fortytwo inches in diameter, made of
Inspected iron plates at least onefourh Of inch thick
in thebest manner and of the quality herein required
and shall rate the working power of all hghpressure
boilers, whether of greater less diameter old
accoSng to their strength compared with this standard
and n all cases the tost applied shall exceed the working
power allowed in the ratio Of hundred and sixtyve
TO one hundred and ten and highpressure boilers
hereafter made shall be rated above this standard and
in bjecting to the test aforesaid that class of boilers
usually designated and known sow-pressure boilers the
said inspectors shall allow working power Of each
newboer pressure Of only hreeourths the number Of
pounds to the square inch to which it shall have been
subjected by the hydrostac test and found to be su
cen therefor using the water in such tests at tempera
turenot exceeding sixty degrees Fahrenheit but should
such inspectors be of the opinion said boiler by
Of its construction material will not safely allow
stated specifically in their certificate, fix the working
pressure OF said boiler at less than three fouths Of said
estpressure and owpressure boiler hereafter made
sha be rated in its working pressure above the aforesaid
standard and provided that the same rules shall be OBJ
in regard to boilers heretofore made unless the
proportion between such boilers and the cylinders
some other cause renders 1t manifest that its application
wouN be UNJUST in which cases the inspectors depart
fromhese rules if it be done with safety but in
case shall the working pressure allowed exceed the by
rosc test and valve under any circumstances shall
be loaded managed in any way as to subject boiler
to greater pressure than the amount allowed by the in
specors, shall any boiler pipe be approved which
is made in whole in part of bad material is unsafe
in its FORM dangerous from defective workmanship
age, use, or any other
Fourth. That when the inspection in detail is com
pleed and the inspectors approve of the vessel and he
equipment throughout they shall make and subscribe
certificate the collector of the district substantially
follows:
State of ---, District Of
Application having been made in writing by ----
to the subscribers inspectors for said district te
examine the steamer --, Of -, whereof ----
-- owners and - is master, we, having per
formed that service, now, on this -- day OF -----
ammo Domini - do certify that she was built in the
year - is in all respects stanch, seaworhy, and in
good condition for navigation, having suitable means
escape in of accident from the main to the upper
deck that she is provided with the number
the number of berths therein the number
other permanent berths for cabin passengers the number
of berths for deck other classes of passengers the
number Of passengers for each class for whom she has
suitable accommodations and in of steamers sail
ing to from any European port to from any por
on the Atlantic or the Pacific distance of thou
sand miles upwards the number Of each she is per-
mitted to carry and in of steamer sailing to any
other port, distance of five hundred miles up
wards the number of deck passengers she is permitted
to carry also the number of boilers and the FORM dmen
sons and material of which each boiler is made the thick
of the metal and when made if after this act takes
effect and Of iron whether they are such in all respects
the act requires whether each boiler has been tried by
hydrostac test the amount of pressure to the square
inch in pounds applied to it, whether the amount allowed
as the maximum working power was determined by the
rule prescribed by this act if not the for depar
ture from it, also the number of safety valves required
their capacity the load prescribed for each valve how
many left in the control of the persons navigating the
vessel whether is withdrawn and the manner Of Sc
curing against interference also the number and di-
mansions Of supply pipes and whether they and the other
provided sufficient at all times and under al
circumstances when in good order to keep the water
four inches at least above the top Of the ue also the
number and dimensions Of the seampppes, the number
and kind Of engines, the dimensions Of their cylinders
the number and capacity Of the forcing and hov
worked the number and kind Of gaugscoaks water
gauges, where situate and how secured also tn
Of using aoyed metals and the pressure at whic
they known by the inspectors to fuse the qupment
for the extinguishmcnt Of fires, including hose fire
buckets and axes the provisions for saving life in
of accident including boats lfepreservers and subst
tutes therefor where kept and all other provisions mad
board for the security of the lives Of passengers
And further certify, that the equipment of the vesse
throughout including pipes pumps, and other means
keep the water up to the point aforesaid hose boats life
preservers and other things is in conformity with thu
provisions Of law and that declare it to be de
berate conviction founded upon the inspection which
have made that the vessel may be employed as steamer
upon the waters named in the application, without peril
to life from any imperfection Of FORM materials work
manshp or arrangement Of the several parts or from age
or use And we further certify that said vessel is to run
within the following limits to wit: from -- TO --
and back touching at intermediate places.
And which certificate shall be verified by the oaths Of
the inspectors signing it, before person competent by
law to administer oaths. And in case the said nspec-
tors do not grant certificate of approval they shall state
in writing and sign the same, their reasons for their dis
approval.
Fifth Upon the application Of the master or owner OF
any steamer employed in the carriage of passengers for
a license to carry gunpowder, oil Of turpentne, oil Of
vitrol camphne other explosive burning fluids and
materials which ignite by friction either Of them, the
inspectors shall examine such vessel and if they find that
she is provided with chests safes composed Of metal
or entirely lined herewith more apartment:
thoroughly lined with metal distance from any
fire. thew NAV grant certificate that effect authorizing
such vessel to carry freight any Of the articles aore
said those Of each description be secured in such chest
safe or apartment containing other article and carried
at distance from any fire be specified in the cert
cate ropd That any such certificate may be revoked
or annuled at any time by the inspectors upon proc
that either OF the said articles have been carried board
said vessel at place and in not authorized by
such certificate that any Of the provisions Of this
in relation thereto have been violated.
