THAN SOLID HAIRCUT
DOWN EXPENSE.

Mine drills need no longer be sharp
ened. The old cumbersome process OF
shaping and sharpening drill bits is
in the discard. The "nipper'' scurry-
. ing through the levels, gathering up
drills will soon be a thing of the past.
i Precious hours spent in hoisting dull
drills and lowering sharp ones will be
saved. No more time need be lost by
miners waiting for sharp steel. The
tearing and damaging of shafts, the
killing and injuring of worl1men
through drills falling from the cage or
being thrown down a raise will soon
be things of the past, says the Ana
conda Standard.
mo longer viii it be necessary to tie
up thousands of dollars in bar steel
for drills One drill shaft will be suf-
icient equipment for each machine.
Dollies and dies will no longer be
needed. Tool sharpeners will be dis
pensed with Mining men state that
these Improvements mean a wonder
full saving to the mining industry.
Invention Described
All this comes about through a
simple invention, the product of the
genius of a Butte man, Arthur L.
Haiwllesworth master mechanic at
the Butte mines machine shop Mr.
Hawk esworth has invented a remov-
able bit for drills. This bit may be
made Of the finest steel, while the
shaft to which it is attached may be
of cheaper grade The steel is melt
ed in an electric furnace and poured
into the desired shape. This guaran-
tees uniformity Of size, something that
is practically impossible under the
sharpening system. and means a
cutting point of an infinitely higher
the old process.
These points lock with the drill
shaft on a bevel. There is a center
locking" device also AS result of
the bevel. each blow of the drill serves
to drive the tip tighter and ever
tighter on the shaft. The center lock
prevents the point from getting out of
alignment When the bit becomes dun
a blow with a hammer lOOsens it and
a new one can be substituted in an
instant These points weight only 81
ounces. The miner can take a couple |
of dozen points with him when he
goes on shift and will never have to
lose a minute because of duh drills.
A ton of steel will make 200 drills
such as are used at present. A ton of
steel will make 5000 of the new drill |
bits. When the bits are worn out
they are dumped in the electric fur
mace. melted to the proper tempera-
ture and poured again into new. sharp |
bits ready for use.
Tests Verify Claims.
The proof of the pudding is said to |
be in the eating. The proof OF the |
value of the HawkeswOrth invention |
is IN its work A number of expert |
enced but skeptical mining men gath
cred a few days ago to test out the
new invention. The hardest granite
obtainable was used for the test. A
run of two minutes was made with
an old style drill, after which the hole
was measured. The depth was eight
inches. Then the Hawkesworth bit
drill was substituted and a second
hole was started. In two minutes the
drill had cut to a depth of 1875 inches
The Investigators were not satisfied.
Another test was made. The score
stood u inches for the HawkeswOrth
point and for the old-fashioned
drill Another driler was then tried.
His score was IL inches; the ,
again showed IS inches.
The Investigators expressed them.
