struggling with the problem of re-

life for low grade ore bodies through
out the world. says the Anaconda
Standard Of May IA.
These four ounces of steel represent
the detached drill bit invented by a
Butte master mechanic who for 20
years, in company with thousands of
others of his craft throughout the
world, struggled with the problem of a
detached drill point possessing all Of
the qualities of the solid bit. coupled
with the advantage of detachable
point.
Although the quantity manufacture
of these drill points has not yet been
accomplished, already orders for the
new device are coming in from Michi-
gan, Nevada. Utah. Arizona, British
Columbia and far-away New Zealand.
The railway contractors of the United
states have had their attention aroused
and they. too, wish to try the new de-
vice, which has been described as the
life saving. time saving, labor saving.
money saving drill"
A New Epoch
The Hawkesworth drill. like many
enother epoch making invention, is
simple A drill shaft is thickened at
the bit end and slot an inch deep is
cut into the metal The end Of the
shaft is cut on an angle. The slot is
toward the upper part of the "shoul-
der Of the shaft. A point is then cast
in an electric furnace or made by
hand. This point has a stem which
fits into the shank slot The shaft be
ing cut on an angle. every blow on the
point drives it further up the shaft
1t cannot go beyond certain point-a
center-by reason of the character of
the slot. 1t can not slip out of place
because each successive blow has only |
one effect-a tightening one
1t is now three years since the |
Hawkesworth drill point began to ring
against the granite blocks on the Ana
conda hill, with the inventor consulting |
and testing each feature When it was /
finally demonstrated that here was
drill without equal in the mining world. |
This invention drew the attention of /
mining men and drillers the world |
over
Officials of the Anaconda company
were the first to take a serious interest
in the invention. The new bit was
tested by them under a multitude of
conditions What this immense en-
ployer of mining labor thought of it is
shown by the fact that it has laid plans
for a plant to manufacture the drill
points in Anaconda, and quantity pro-
duction will commence about July
This, after the company has used the
points all over the hill. in copper water
and out of it. in soft ground and hard
