A GREAT TUNNEL BORING MACHINE.

revolution will be affected in tunnel mining drilling
machine which being operated by the Utah Harms Tunneng
Machine company will do all its manufacturers claim for and
which tests made bear This machine being
constructed with view guaranteeing 1000 feet Of tunnel work
month"; The machine is the invention of P Harms of Boulder
Colorado who acknowledged be of the best practical drill
operators and rock in the United States The p Harms
Tunneng machine has built under his direction several
machines Of these the first constructed to demonstrate the
principal efficient and only operated for experimental pur
poses but gave a satisfactory account of itself.
The six feet in diameter and
completed experimental and demonstave work. about thirty
five feet Of tunnel successfully making record of five
feet four and quarter inches tunnel hour and twenty
nine minutes presence number the prominent
engineers in the country While this machine embodied many
improvements the first the inventor found to
make several radical changes in the carriage and other details
Another machine embodyng the various improvements worked
by the inventor constructed and placed contract work
for the Manufacturers Water Supply company Johnsown
Pennsylvania where 0foot tunnel is being driven by the
p Harms Tunneng Machine company After operating
fully for some distance found in the head of the
machine which will result in temporary delay in order to
sruct head. This will be completed possible
Becher president of the Utah Harms Tunneng company
and Gilbert associate have been studying conditions in
the Occur dAene for the week with view to introducing
the machine here later In speaking Of the result and
poets Mr. Belcher said:
after nearly years of continuous work against skeptica
public and supposedly scientific mechanics the promoters of the
Harms nneng machine today have the pleasure of seeing
their efforts crowed with complete and have the safac
ton of knowing that they have brought the mining industry Of
this great west invention that is mess in for ad
vancng the mineral production the country and
its field for will extend all the civilized world where
tunnel work of any description is needed.
This invention like all others which revolutionary in
their character has had but few supporters especially its first
two of promotion and for that its
been necessarily slow There has been spent to date on the in
venon something like 900 and the large sums OF money that
were necessary at times, were not always On hand
the mining fraternity of the west wish to announce that
this will meet them just little better than half way
legitimate proposition that has that end in view
and mining companies that first install those machines will
Of course get the benefit.
Several long distance drainage and transportation tunnels will be
BY the in deer mining districts and where these
tunnels deals will be ,ade with the various mining
psnies effected for drainage transportation that will be salts
factory to all concerned"
