Union Pacific Locomotive #119 and Central Pacific Locomotive #60 ...

upon the frame. On top of the flange of the expansion plate is
another wrought iron plate, with a lug at each end, which rests on the
frame and is bolted to it. The latter plate has round holes, and the
expansion plate has oblong holes to receive the expansion bolts which
pass through the frame. Each bolt has a washer on it of the same
thickness as the flange, and received by the oblong holes. The top
plate is then bolted down hard on these washers, and is stationary on
, the frame, while the expansion plate moves with the boiler. When
a pair of drivers is behind the fire-box, a wrought iron clamp is
bolted outside both the expansion plate and the frame. This clamp
holds the fulcrum for the equalizing lever, and runs down with a foot
and a.bracket. .The-foot is-bolted to the fire-box, while the bracket
rests on the bottom bar of the frame, and has oblong holes the same
as the expansion plate, with washers, and a top plate bolted'down
hard on the washers. The top bar of frame is fastened to the firebox
"by additional wrought iron clamps, and the bottom bar by
wrought iron brackets where they are necessary. • -
" ; FRAME BRACES. ' .
. A tail brace made of hammered iron extends across and is let into
the back end of each frame. It has a Q shaped piece forged on it,
to which the draw casting is bolted. All engines with the exception
of some anthracite coal burners, with long fire boxes, have two braces
made of roimd rolled iron bolted to tne tail.braces next the frames,'
and extend upward, at an angle of about forty-five degrees to' the
shell of the fire box, to which they ETC bolted with a suitable foot.
A wrought iron cross brace is bolted to each frame in front of the
main driving axle. An angle iron, made of boiler plate, is bolted to
this brace, and riveted to the boiler. The angle iron has a projection
or Ing to hold the counterbalance spring.
The frames which are spliced have a brace, the foot of which is

held by two of the splice bolts, and the other end is riveted to the
shell.of the boiler. • .
The front ends of the frames are braced to the smoke-box by a
brace made of round rolled iron, and bolted to the top of the bvimper
timber and the.frames by a foot with a lip, which locks against a.
corresponding lug on the frame. The foot has two bolts which pass
through the timber and frame. The. upper ends of the braces are
bolted to the smoke-box by a suitable foot. .
DRIVING SPRINGS ..
are made of cast steel. Each plate is punched'in the center so as
to make a cavity on one side and a projection on the other, which
prevents the plates from slipping.' A band is then shrunk on the
center of the spring. The spring hangers, are made of hammered
iron. The ends which are attached to the frame are hung on rubber
seats. The saddles for driving springs are made oi cast iron, and
rest in sockets cast for the purpose in the driving boxes.
' -. . . EQUALIZING LEVELS. ... . •
All engines with the exception of those with only four wheels,
have suitable equalizing levers between the driving springs.
CYLINDERS
are all horizontal, cast of Lake Superior charcoal iron : one half the
saddle, the steam and exhaust pipes are cast on each cylinder. Both
cylinders are alike, and are bolted together at the center of the engine..
The smoke-box is round, the cylinders are fitted and securely bolted
to it. The cylinders are bored,.and the flanges turned and.faced to
gauges, then planed parallel with the bore, and the face of one where
they join each other, drilled through a template. They are placed
together, leveled by the frame seat, and the second cylinder marked
off and drilled, then clamped together and the holes reamed, and the
