Board of Trade, Aseistant Secretary,
Marine Department:

DAFT OF REGULAIIONs REFERRED TO IN THE An ,VE
NOME As TO THE TESTING eF CAST STEEL ANCHORS.
1. The regulations as to the marking and certifying
of cest steel aechors sha:l be the same as arc now in
f re for wrought iron anchors, but, in addition. the
words "cast et-el" must be stamped on each anchor, or
on each east steel portion of the anchor when it is made
of more than one casting ; and for the present the ex-
turination of and proof strain to be applied to, such
anchors shall b 3 the rams as are now in force for
wreught iron anchors of equel weight, but the statutory
prof strain mutt not he app:ied to any cast steel anchor
tuna the meterial of wh:ch it is made has been tested for
tinsile strength an ducti,ity and found satisfactory,
2. The tests for tensile strength and ductility must
be made at a public Proving Establishment, where it
is inteaded to apply the proof strain.
3. There must be three pieces cast on each anchor,
or on each piece of the anchor when it is made of more
than one casting, two of which must be tested for tensile
strength, contraction of area and elongs.tien, and the
other must be beet while celd. These test pieces must
Le fairly distributed over oar casting.
4. No cast steel anchor. or pertions of a east steel
anchor, should be received at a Proving Eetablishmeet
w th all or any of the test pieces broken or cut off.
5. When a superintendent of a Proving Esteblish-
mt nt receives a cast steel anchor for testing purposes he
should at once have the test pieces cut off, then have
teem prepared and tested, and, if the Testi ts are satis-
f• en:ay, he should, if the anchor seems bound. app;y the
proof strain.
G '1 he pilling pieces must be turned in the lathe to
lie, diameter for a length of 10in , and the elongation
token in that length.
leln bending inecee must be machined to lin. rquare
for a length of l2in , and but by screw or t Id.eulic
pressure on supports 10in. apert until y pass between
trio supports ; they are then, if uncra ked, t..) be bunt by
areesizg the ends together until they breek, titan
teeir sides are latallel at a distance of 3in. apart,
reeesured inside.
a he end of the hydraulic ram, or part that presses on
the test pieces, sanuld b serni•cylindrieal. the radius
b lug lb., audits depth eliou.d be at least 2in.
7. 'I he tensile strtngth'ef the test pieces should not
c xceed 10 tens per square inch of section.
et he
.cintraction of area of the test pieces at the
fracture sLeuld not be is a than 4- 'ear cent
Ihe elongation if the teet pieces in a length of 10in.
thoual nt ne less than 18 ler cent.
I he bending test pitcee sheuld bear bending until the
s id,a are parallel ate distance apart or. 3iu., measured
iiiei .0 eithout flew or fracture.
8 If the teosile strength exceeds 30 tons per square
itica of section, the results of the ttsts are to be re-
warded as unsatisfactory, and unless two out of the three
tests for ducti ity. viz , contraction of area, Elongation,
and bendaig, be in accordance with the requirements
etated herein, the results of the tests are sleo to be re-
garded es uneansfactory.
O. aleteriel which contain.; blow-holes cannot be
regarded as smtebte, and the proof strain ehoula not be
_ applied in such cases; and when leoer-holes are bserved
. in a tested alle.:or it :lieuid not lee certified to.
s 0. Ihe anchor shackle and its I nit, together with
such parts as forelocks, must be made of wiought iron.
