The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1923-02-22


Foundry company of this city,
being situated i'm the heart of
one of the great mining districts
of the west and being under the man
ogement of men who have long been
identified with large mining opera
tons. has in recent years been con
centrating it's efforts toward the con
struction of mining machinery and
equipment to meet the requirements
of practical, economical and efficient
operation. Profting by the defcien-
cies of machinery products manufact-
ured far removed from the scene of
actual mining activity this company
being on the ground and in close touch
with the mines has been able by pa
tent effort to solve many of the me
chanical problems which have been
the cause of veXation and loss. The
success achieved by this company is
effectively demonstrated by the fact
that its machinery products are rap
idly supplanting all others in the
mines of the Occur d'Alene district
and its field is steadily extending
throughout the west. Equipment man
ufactured by the Occur d'Alene Hard
ware & Foundry company is now used
in the mines of Butte and other sec
tons of Montana, in Utah, Nevada.

The Company's Products.
Practically everything entering into
mining operations in the way of ma
chinery and metal equipment is man

tensive plant in this city. The spe-
cialties of the company are the wal
lace" sand pump, the Taylor" and
Ajax" ore cars and the Occur
d'Alene" hoist, all of which have been
subjected to the most exacting ser
vice and have proved their superior
ity- The company is just now COM
pleting an order for 40 Ajax" ore cars
for the Butte & Superior mine at
Butte, an order that was placed after
most thorough investigation by the
Butte & Superior management of all
