SUCTS N SYSTEM
ON HAND TOOLS
Granite Manufacturers and
Cutters Well Pleased With
Initial Operation


A device which it is hoped will elimi-
nate, or at least materially reduce, the
dust menace in the granite cutting in
dustry was tried out informally before
a number Of granite manufacturers,
stonecutters and newspaper men at
Barely Bros plant yesterday after
noop While the device is still more OF
less crude and in the experimental
stages, the benefits seemed to exceed
those Of any device thus far tried out
on hand tools In fact, so well pleased
with the initial demonstration were the
manufacturers that the matter OF fur
thering the project was taken under
consideration at a meeting of the Barre
Granite Manufacturers association this
afternoon.
The device is by no means new in
vention but rather an adaptation OF
mechanical contrivances already in use.
In brief, the device Is but the adapta
tion of the vacuum cleaning idea, the
drawing Of the dust from the stone by
means OF a suction fan. 1t is like the
big exhaust used on the surface cutting
machines only on a small scale. The
exhaust pipe is attached to the pncu-
matte tool, being held about two inches

it moves with the tool over the gran
ita and as the dust flies from the point
of the tool it is sucked into the exhaust
pipe in great quantities.
Under normal pressure of the pneu-
matte tool on the stone yesterday aft
ernoon practically all the dust that
could be detected with the naked eye
was drawn into the temporary receiv
! ing pipe. which was nothing more than
! piece OF one-inch rubber hose
! This dust is drawn by four inch fan
! 1.-THE same that is used in the ordinary
vacuum cleaner in SO many homesl into
dust receiver and is there held until
removed by the workman at the end of
| she DAYS work. At times, in order 10
give an idea of the quantity, of dust
drawn into the bag, the pipe was de-
tached yesterday at the point of en-
trance to the receiving bag; and clouds
of dense dust mostly granite but also
containing particles of steel-were
| blown into the air Further to illustrate
! the effectiveness of the device, the ac-
cumulaton of II hours operation OF
the little machine was shown, the eX
hibit being FIVE pounds of fine, -four
! like dust, feeling soft to the touch but
being OF an insidious nature when car
ried into the lungs
Whether the dust as drawn into the
receiving tube is to be deposited, when
| the maehine is perfected, into recep-
tacle like the pouch of vacuum clean
er or * TO be driven outside OF the
stoneshed in the same manner as the
devices on the surface cutters remains
to be determined as the idea is worked
out moro fully. 1t is expected that The
dust can be deposited outside of the
stoneshed without great trouble.
The demonstration yesterday OF the
drawing power Of the dust-remover was
hy no means final inasmuch as the ori
fee of the receiving end Of the pipe had
no fauge whatever, being simply
piece of rubber hose. as already stated.
| II IS predicted that with a special
aapee the device win catch the dust
more easily and that there will be prac-
icallv no escape Of dust into the air
surrounding the granite cutter.

Another distinctive purpose carried
ont bv the new dust-rcmover is to clear
the accumulation of dust from the
stone As Is well known. the granite
cutter is hampered by this accumule-
tion 40 that he has 10 remove the dust

the stnuecuiters used small brooms TO
sweep the dust of latterIy they used
the powerful pressure Of compressed
air. which did the job thoroughly but
stirred up such a dust that the stone

over the surface of the stone and all
the dust is sucked up the exhaust pipe,
