lIlCIlOn W Tie HALL drivers.
Enclosed please find cut illustrat-
ing the bull with pilot and tender,
with an additional dome and straight
stack for burning coai.
The first sixteen locomotives on
the Camden & Amboy R. r. were
whatiis termed inside connected, or
English, type of locomotive. The cyl
finders Were secured to the bottom of
hthei GIh6kel box. The center of the
cylinders were two feet three inch
above the rail, the guides extended
back under the cylinder part of the
boiler, and each set of guides was
secured TO two inside iron frames,
one end Secured to the smoke box,
the other end to the front of fire box.
These, frames had forked or open
Jaws, over the driving axle. In these
jaws was secured a set of brass
t4an&ed-boXes, one set on each side
of the cranks. On the bottom of
these forked jaws was secured bot
tom braces; in these braces were adj
justing screws, for adjusting the we'd
ges on these center bearings. Be-
tween the two inside bearings the
eccentrics were secured to the driv-
ing wheel aXles, one eccentric wheel
for each set of rods, and connected
to the wheel with one eccentric strap.
pThese rods passed forward between
ohe ~loylinders to the front of the
smokeIboX, and was connected to the
valve stem that passed out through
the front of the smoke box, by 4
rocker shaft. On one end of this
shaft was a double arm, a pin in
each one for each hook. Near the
center of this shaft, in line with the
valve stem, was a tow arm that fitted
into a yoke forged in the valve stem,
in which were inserted two steel
gibbs. This tow received it's motion
from the %eccentrics and gave the
proper motion to the valve.
This type of engine was classed as
single valve motion, and the follow
ing engines had this movement: Nos.
/, 2, 3, 4. 5, Z, $40, IL, IS and IA.
The following locomotives, Nos. 6,
8, ~, Is and 16 all had independent
cutoff attachments. The valve mo-
ton of this type~of locomotive were
outside the main frames. These
frames yer of oak, framed and bolt
ed together. One of the hubs under
the A foot 6 inch wheels under the
John Bull, had a long hub or sleeve
extending in and near the center of
the axle shaft. This hub was bored
to fit the axle, on which it turned.
The object was to allow the wheel
to turn a curve without slipping. The
aXles of both pairs of wheels were
secured in brass boxes, set in wrought
iron ~pedestals. These pedestals were
secured to the wooden frame. The
driving or crank axle was Just for
ward of the fire box and in close prox-
unity to it. The rocker shafts for
the last named cutoff locomotives
were suspended above and secured to
the main frame of the locomotive an
wrought iron uprights. These up
were braced from the frame
and smoke box, connected up similar
to the single valve engines, with the
two eccentric rods, for the main
valves were moved from one eccentric
wheel. This wheel was keyed on the
outside on the driving wheel axle,
outside the main driving box, and
outside of this a crank was secured
gave motion to the rocker shaft,
that worked the cutoff valve. This
shaft was suspended on the same
frame as the rocker shaft for the
main valve. The arm and tow in this
shaft were both turned down to ad-
NIT the yokes of the main cutoff
to clear each other. In all
of this class of engines, the reverse
was very similar, getting its
from a reverse shaft sus-
from the top and front of the
smoke box. arms keyed to this shaft
with rod connections led down to the
eccentric rods, and an arm Keyed to
he same shaft with a rodfled back
over the top of the boiler the en-
who stood directly Rack of II.
Each engine was reveJ$ed separ-
ltely. The end of the rev rse Q IN
