Active work toward saving the lost
submsrine IA win be resumed today.
Dragging will be begun by the United
States trg Navajo and the Young tug
Malaala, In anticipation Of the com.
lletion Of the seows for pontoon work.
Besides, the diving bell probably win
l'be sent down with Jack Agraz as its
iret occupant at great depth. 4
| phe Navajo win 60 to Pearl Harbor
this morning to tow the dredge Gay
lord 70 the wreck. This dredge has a
boon that viii ''top, ,, or move up and
Town.. That Of the California win not.
II win swing only. The better bobm
will permit faster operations. vi
Lines Tor Dragging Ready
-Four big lines, one two-inch steel
able and three two-and.one-hel
| inches, are ready to be taken out 10 The
place where the F-4 lies. They lay
Istrctchcd out on the navy wharf yes
terday. These will be used today BY
| he Navajo and Makaala in an effort
"a get hold of the F,4.
|, After holds have been caught. the
| ines will be transferred 10 the Gay.
ord, which will keep them fast until
.he scows have been fitted with shafts
md other iron work being done at the
donoluln Iron works. Then they win
be elamped to the shafts and the pom
DON system put into operation. 4
Another perplexfng problem was met
yesterday by Commanded @. w. Parks,
ngineer In charge of the diving bell
ind lights for the andersen work, and
lieut. q. 81. Burrell, his assistant,
hat Is providing illumination. ll
Plato Glass Breaks ~
Incandescent globes Of proper
itrength are available A cluster OF
our of 1000 watts each viii be used, TO
hang directly above the submarine,
swinging from the same boom that
lsoids the bell. But fitting the tubes
:ontaining them with glass ends is Civ
ng trouble. -Four were tried out yes
terday at about $50 feet, The metal
tubes ten inches in diameter, had plate
lass oAesineb THE 4 at the lower end,
Three broke Auhde the pressure One
seemingly had i thicker rubber gaeket
han the Others and Mr.. Parks thought
hat possibly the reason the three broke
| vas that they pressed against the
Emetal. A piece Of quarter-inch wire
| ylass broke at sixty feet. It Was
sheared off elcanlg. In circle, where
tube had rested.
1t was strange, too, that only one OF
20 globes broke They are of the usual
hin glass, aud yet withstOod pressure
| aat broke inch glass.
Heat Also Problem III
The problem Of heat generated BY
he globes also may be troublesome
four powerful lights win create
quite y dlnerenee OF Temperature be
ween the interior and exterior. Thus
he glass plates will be hot on the In.
ler side and cooled BY the sea water
IN the outer, Mr.. Parks win continue
| % try to use inch glass, fitting the
plateg with thicker gaskets Tests OF
glass were made by Mr.. Burrell yes
terday. lltR X
Lieut.. Charles L. Smith, commander
| the submarine Aotilla, said that he
expected to use the bell as soon as it had
been turned over 10 him, Mr.. Parks
said that he Considered it completed,
and that Q submerHion today hardly
was q test. q. sa,
II IS expected, therefore, that Agraz
will 70 down some time this afternoon,
-He may come up with definite word
pf the condition Of the submarine, not
only rs to how she lies, which is OF
greatest interest to the salving crews
low, but also as TO whether her plates
have collapsed or whether she dived
aeaafTst or possibly, other details, oh,
lseryRhle front W 3 exterior, which might
give the Arst mixing as to how she met
ler end. a.
pressure of possibly three atmo.
spheres will be maintained in the bell
at ESQ feet, the depth of the sub
marine. This would counterbalance the
sea pressure To some extent, but the
,rincipal reliance viii be placed on the
strength of the iron shell. No attempt
viii be made TO maintain great in.
terior pressure, laf
Moderate Initial Test =
The first test with a man inside will
be made at q moderate depth, say Of
sixty feet, and air lines and telephones
win be gone over thsroughly. The
Telephone particularly is Important,
since It will be the sole communication
with the surface, although the bell
would be drawn up Immediately should
communication cease. z
| The bell and lights win swing from
one boom. The lights viii be heavy
enough to Keep practically plumb,
and this plan win make their position
easy TO regulate with reference TO the
submarine and bell All the illumina,
Ion will be shed through the glass in
the lpwer ends of the tubes,
SEIZED cows ARE SOLD.
