THE GRANT LOCOMOTIVE.<br />
•••• , : VALVE GEARING<br />
is the shifting link motion. The links.are forged of Low Moor Iron<br />
' <strong>and</strong> case hardened, <strong>and</strong> are made either solid or skeleton. They are<br />
hung in the center vertically <strong>and</strong> back of the center, horizontally.<br />
The suspension pin is forged on the saddle, <strong>and</strong> the latter is bolted<br />
to the link.<br />
CONNECTING RODS<br />
are made of best hammered iron. The body of the rod -is tapered<br />
from the front to the back end. The corners are chamfered off, <strong>and</strong><br />
the rod accurately planed, <strong>and</strong> finished all over. The front end has<br />
.a strap <strong>and</strong> two brasses. The lost motion is taken up with a key<br />
placed vertically in the stub end, <strong>and</strong> secured by double nuts. .The<br />
key bears against, a wrought iron plate. The straps are held by two<br />
• bolts.* . . • .<br />
The back stub end has two brasses, which are held by a strap<br />
bolted to the rod with two bolts. The lost motion is taken up with<br />
a key, which is secured with lock nuts, <strong>and</strong> bears against a wrought<br />
iron plate. - . . . •<br />
';•-'. COUPLING-RODS<br />
are made of best hammered iron, planed <strong>and</strong> .finished all over, with<br />
the corners of the body of the; rod chamfered off. Each'of the' crank<br />
pin journals has two brasses, held with straps bolted to the rods with<br />
two bolts, . The lost motion is taken up with suitable -keys, secured<br />
with lock nuts.' ' ' • '<br />
• •"•• : • 'LIFTING-SHAFTS<br />
are made of wrought iron, forged solid. The arms have wide taper<br />
— — $ — -——'<br />
* The rods which are used with cross-heads having two guides have solid ends<br />
in front, with two brasses,'<strong>and</strong> a horizontal key. . \<br />
All the brasses of the connecting-rods are Babbitted, <strong>and</strong> each journal has<br />
one of picker's patent oilers. • . .<br />
bearings for the pins of suspension links. The vertical arm to which<br />
the reach rod is attached, is curved so as to clear the boiler. The<br />
ends are supported by cast iron st<strong>and</strong>s, bolted to the frame.<br />
In the center of shaft is a short arm to which is attached a- rod<br />
which passes through two volute springs, which serve as a counterbalance<br />
for the links.- '•. ' . - . ' • .<br />
REVERSE LEVEK.<br />
The fulcrum is at the frame. The quadrant is made in two parts,<br />
case-hardened, <strong>and</strong> notched:;tohojd the lever in the desired position.<br />
The lever is connected with 1 the lifting shaft by the reach rod, which<br />
is supported by a bracket, fastened to the running board.<br />
."•..•' • : ECCENTRICS<br />
are cast with a boss on one side; they are bored <strong>and</strong>' turned to<br />
special gaug"es. Each eccentric is fastened to the axle with two steel<br />
set screws, cupped on the end.<br />
- '. ECCENTRIC-STRAPS<br />
are cast iron. They are bored, out with a recess to receive the eccentrics<br />
; all parts accurately made to st<strong>and</strong>ard gauges. 'The two parts<br />
are joined at an angle of forty five degrees, with the center of tKe<br />
eccentric rod. An oil cup ..is cast on the top of the back.half} arid an<br />
oil cellar on the bottom of the front half.. -<br />
.'••.. •-. • • ECCENTRIC-RODS. • •<br />
• are bolted with three bolts;to the straps, <strong>and</strong> have a jaw on the front<br />
end to take the links. A pin with a steel thimble, which turns in the<br />
link, is fitted into the jaw. ; •<br />
DRIVING-WHEELS.<br />
The driving-wheel centers are made of cast iron, with hollow<br />
spokes <strong>and</strong> hollow rim* The section of the spokes is elliptical. The<br />
hubs, for axles <strong>and</strong> crank pins are. cast solid, <strong>and</strong> are flush with each<br />
