stats of the Anaconda company take first
rank among the worlds outstanding
business organizations" MIR. Alley said.
After several years of exhaustive, large
scale tests by the scientific and practical
men of the Anaconda company, the de-
cision has been unanimously reached to
standardize on the Hawkesworth steel.
1T is only just to say that during the
period in which we we're working out
this great revolutionary change in the
type OF mine drills, a period which W.
cred years of testing underground, of de-
vising special processes n building spe-
cial machines to insure both quantity
n quality in production, we have had
the consistent. unstinted support Of the
Anaconda company, from the commence
ment of our experiments right down to
this minute 1t is a fact that, without
that generous cooperation and support
1t is unlikely that u enterprise. now so
successfully launched, would ever have
been even undertaken.
Gables from Europe
Senator Harry A. Gallwey, who has
been actively identified from the very
beginning with the Hawkesworth COM
pany and who is vice president and di-
rector of the company, is now travelling
in Europe. He cabled from London, ex-
pressing ulb ltdIIy BldJllCdblOu anu,
quite in line with his usual disposition,
spent a good many American dollars In
q statement in which he divided the
credit for the present highly satisfactory
situation between the Anaconda COM
pay, the crew of craftsmen M inventors
of the Hawkesworth company who have
worked SO ~zea1ously n to such good
purpose"
When asked regarding the future plans
Of the Hawkesworth company, Mr.. Alley
stated that, after q short rest, he would
go forward with plans now under way
for plants in other parts Of the country
to supply the general market.
The HaWkeSWorth bit is simplicity
1t means thousands of dol
lars saving a month to even the smaller
companies-savings on invested capital
in steel, saving in time spent in sharpen
ing drills, saving in time in hosting
drills out of the mine and in returning
them, saving IN steel thrown n "gobs'
by careless miners and, above all else,
the elimination OF the risk that is al
ways attendant on raising and lowering
steel In the deep mines.
The Hawkesworth bit is cast in an
electric furnace and tempered to such
hardness that diamonds are used to grind
It's edges. 1t is q small piece of steel,
not longer tina a couple of inches. The
piC ana the urlll SnanK With which 1t
unites are bevel-shaped at their contact
ends. Out Of the end of the bit extends
a sort OF V-shaped hange. In the end of
the shaft there is a slot to receive his
V-shaped protuberance. The "V" enters
the slot at the lower end, with the result
that each blow on the points OF the bit
drives 1T upward along the bevel until 1t
reaches the exact center Of the shaft and
there. the slot narrowing at this point.
the ~" can go no farther and the drill
is held firmly In place.
A slight blow on the side of the drill
will loosen the point. Whenever 1t be-
: comes advisable to change it, the miner
taps his drill against the leg of the tri-
pod or with a hammer, drops the old
point. reaches into his little canvas bag,
in which he carries a dozen points or
more. puts on a new bit and resumes
drilling, with the time for Changing steel
reduced to a minimum.
The new drill points are checked out
