THE GOLD HILL FOUNDRY.
a Dusy Well.Csnduetsd Estsbiish-
usas-what Kind OF work eau
ana 10 Being Done There.


We paid a passing visit to the above
establishment yesterday. and were politely
shown through by Mr.. George Emmett,
the proprietor.
We found business brisk In every
department. In the foundry. which Is In
charge Of Mr.. Lercy. q quarter Of q spur.
wheel for the ophir mine has just been
cast. the casting was perfect In every re
spect, and the teeth were rs smooth ~
glass; great care was taken In selecting
the iron for this casting so n to have II
Of Q uniform texture corresponding a.
near - possible 10 the othss parts Of the
wheel which was made at the Risdon Iron
work.. San Francisco. The fitting OF
this segment to the other three pieces will
be done In the machine shop under tho
supervision Of Mr.. James Brown. This Ia
. more difficult task than the construc-
tioa Of . whole wheel ut N time. for the
teeth must be on the SAM circle and the
same distance apart as the toeth In the
rest Of the wheel. After this segment 10
planed 90 % to at. It will DO bolted to the
other three. making . whole wheel. II will
then DO lifted by the crane into tho lathe
capable Of swinging . larger wheel than
any other lathe In the State. Hero II will
be bored and turned for the bands. This
will have 10 be done without taking any
thing OF three OF tho segments. ~ II has
10 DC the same shaft that II came of from.
and the Same bands are 10 DO used again.
When this 10 done the teeth will DO cut
precisely the same Is the rest Of tho wheel.
In Q large gear cutter that IL capable OF
cutting teeth Of wheels from one foot In
diameter up TO nineteen feet. Tho wheel
we are speaking Of. belongs to the double
hoisting engine at the 0phir mine and Was
broken several months ago by the cable OF
the rear engine getting into the gears. IL
IL about twelve and one-hAlf inches In de
ameter. fourteen inches In the face and
four and ono half inches pitch. and weighs
eight tons.
In taking the broken wheel apart the
iron bands round the hub were removed
by an ingenious continuance OF Mr.. Foote,
the chief engineer at tho 0phir. In order
70 expand the heavy bands without heating
the rest Of tho wheel q circle Of gas pipe
WAS male with Jets arranged 80 as 10 play
all round the bands and heat them uni.
formly. The same process will DO used
again TO shrink the bands ID.
some Of the other work In course OF con-
.struction at tho Gold Hill foundry consists
In . spur wheel and pinion for the Sierra
Nevada mine, Q balance sheave for carry
ing 80 tons Of pump-rod for tho Succor
mino this device IL q new style OF bal.
ancing pump-rods, and Ia the idea Of Mr..
y. d. Segur. Superintendent Of the Sue
cor). large brass sleeves for the pinions at
the New York mine. cam shaft for Bacon
mill. a~rtesian we'll boring machinery, and
. host Of repair Jobs too numerous to
mention.
Two new ten-ton crane have been
added 10 the establishment. They were
designed by John d. Pitchford, who has
sndeavored 10 combine utility. strength
and economy.
Judging from tho tools and appliances
at Mr.. Emmett's establishment. he can
doubtless make any piece Of machinery
necessary for use In this district In the
most expeditions manner
