Ship Tool Building.
The mold loft and ship tool building
has been very carefully designed and is
perhaps the most thoroughly and elab--
orately equipped for saving labor and
turning out work rapidly of any in
1t is of steel, 800 feet long by So feet
wide, with an additional 15 feet of over
hanging shed running the full length.
This side is open, the columns being 40
feet apart and facing the shoreward ends
of the shipbuilding ways
clear eXpanse % Sc of S5xS2o feet. is probably
the largest in America. Being supported
every ten feet by latticed girders five
feet deep, it is practically rigid.
The most noticeable feature of the ship
tool shop is the elaborate system of troll
leys ana crawls for distributing material
and handling it at the machines.
There are twenty-four crawls, ranging
from 6-foot to 1-foot span and are sup
piled with cross trolleys for handling
plates and angles, nine 3-foot gauge troll
distributing material and two narrow
gauge trolleyS for handling angle bars at
the double angle shears and angle planer.
Down the center Of the shop is a row
shearing machines, over which are two
lines of track carrying twelve crawls of
these runs q through track carrying four
3-foot trolleys for distribution. Just out
side this oval are 6-foot gauge tracks for
the four small singlee-ended lie punches or
13-foot gauge tracks for the mast rolls
and Strengthening rolls, and clear across
one end are two 17-foot gauge tracks
completely covering the large 30-foot
bending rolls, which will take plate two
and half inches thick, and the hydraulic
keel bender, which will bend a plate four
inches thick. Material is brought in on
a 9-foot track running the entire length
of the overhanging shed and extending
beyond enough to take from the Gantry
crane running over the plate racks. The
3-foot track is twenty-three feet from
the ground, allowing the locomotive
trains to swing underneath the railroad
the shed. All the other trolley tracks are
fourteen feet from the ground. All the
croSStrackS run out to meet this through
track, so that material can be taken to
any machine in the shop or the finished
work removed without disturbing any
other machine even when all are in use.
there are two radial counter-sinking and
drilling machines working over a long
roller table and various smaller drill
presses.
