ROY ALLEY HEADS
Big new CONCERN
Has financed $3OO,O0 Company for
Manufacturing New Hawkes.
worth Drill Head.

$3.50
John D. Ryan in Montana, with his
office in Butte, has recently resigned
his position and has been elected
president Of the Hawkesworth Drill
company, a new concern which has
been organized to manufacture the
recently perfected Hawkesworth min.
ing drill. The company has beer
financed through Mr.. Alleys efforts
to the extent of $3OO,OOO, and a fac
tory for manufacturing the new drills
for the national and world markets
will shortly be built at some suitable
eastern point. It is beloved that De-
troit may be selected as the site for
the factory.
The new Hawkesworth drill is an
invention that will revolutionize drill
ing in hard rock mines, but it will be
used even extensively in building
construction in larger cities where
deep excavation for building is neces-
sary. AS an illustration of this it may
be mentioned here that in New York
City alone there are, on al average.
$4,000 hard rock miners working in
this excavation work-more miners
than are used in all the mines in Butte,
The Hawkesworth drill does away
with the necessity for sharpening
steel drills used by the miners. In
stead of sending dull drills to the
blacksmith shop for sharpening the
miner will now detach the small
Hawkesworth burr from the shaft of
the drill and insert in the dove-tail
slot a new, sharp burr. This eliminates
the loss Of time and expense incidental
to carrying thousands Of drills daily
from the mines up to the shops for
sharpening and returning them after
blacksmiths have sharpened them.
The Hawkesworth burr weighs only
four ounces, and a supply sufficient
for a shift can be carried in a small
bag. The Hawkesworth drill is said
to be the most important development
in mining since the invention of the
air drill.
Watch a Demonstration.
Veteran mining experts and young
mining engineers watched the new
Hawkesworth drill bite into solid
granite beneath the engine room of
the st. Lawrence mine last week, when
a practical demonstration of the device
was given under the direction of Al
Hawkesworth, its inventor.
Approximately so spectators were
gathered in the room where the test
began. The air drill was mounted
against the face of solid granite that
forms the foundation on which the
huge hosting engine rests at the sur
face 80 feet or more above.
First an ordinary drill TX inches in
diameter was used. The mining men
who examined it pronounced it an ex-
cellent bit of steel. For two minutes
it was driven into the granite, reach.
ing a depth of 8 and one-half inches
Then the new drill head of vanadium
steel of the same gauge was inserted
in the shank, attached to the driving
mechanism, and at the time keepers
signal it started on it's way. In spite
of the noise of the drill it seemed as
if a hush had fallen over the company
as the men stood a-tip-toe to get a
better view of the steel shank that
seemed literally sinking into the stub
born rock. In the two minutes the
new burr was driven 2O1a inches, or
more than double the depth of the or
binary steel drill.
A second test was made with a drill
head that had been gronud down in
r~esharpening to is inches, and this
penetrated % inches in the two min
utes.
All who were present agreed on the
many advantages of the new device,
aside from the quantitative perform
ance. The burr weighs only about
four ounces, so that the cost of the
higher grade vanadium steel is not a
heavy item. Only four shanks with
a supply of drill heads need be kept
on hand, and the miner can easily car.
ry in his pocket the days supply Of
the latter. This obviates the present
necessity Of raising and lowering the
big supply of steel drills, with more
or less danger involved in collecting
dropping and hosting the heavy bars
At present this occupies the engine a
this particular mine for at least az
hour a day.
The item of expense represented i,
the stock of steel on hand is likewis,
greatly reduced under the new v
tenn as the shanks can remain in prac
tically permanent use, turnover bein.
limited to the comparatively small
heads. These can be resharpended b,
grinding, graduating in scale with
margin of one-eighth-inch each time
and this ran be done without retem
pering. Production by machine ais,
lnsures accuracy of gauge that is har,
to attain under the old system of re
sharpening and retempering the drills
Thorough test has been made in 81,
weeks of practical operation on
crosscut in the Original mine, an,
the performance has been convincin,
in its results.
