The Armington G. Sims company of
this city has been experimenting with
n boiler oil injector and the result is
gratifying in the highest degree. The
company has on its property an almost
fnexhaustible we'll of surface WA er.
which. at diffent times. has been used In
the boilers. AID in week there always
was found about an incn of solid matter
in the bottom OF the boiler. as well AS a
slight scale upon the boiler shell and
tubes. This water, which was analyzed
several times seems to contain a peculiar
acid. causing chemical action upon the
boiler plates as we'll as destroying
nearly all OF the brass fittings.
1t was necessary to renew the grooved
boiler plates. and for several years the
company used nothing but Pawtuxet
water. Some time ago a boiler oil injec-
Tor was placed In the works and it has
since been in constant use. feeling about
one quart Of common Kerosene oil per
day to 125 horsepower boiler, which is
entirely new.
The company now usss the we'll waite r
referred TO. After starting the boiler
injector and running IL ten days careful
inspec ion was made. A run OF fourteen
days was then made, with another inspec.
tion, and finally further run OF twenty
eight days. The oil injector has been in
use fifty-two days and the boiler sheets
are "a bright and smooth as when first
started, without scale, sediment or evil
dences OF corrosion OF any kind. The
result up TO this time is extremely graft
flying, and If continued will result ia a
large annual saving.
Providence Machines st the Fair.
Among the important Providence ex-
bibits at the Worlds fair that have not
already been noticed is that OF Messrs.
Beaman g. Smith. consisting OF hori-
xontal spindle milling machine. heavy
standard milling machine, floor and
standard drilling and boring machines
and safety drill aud tap holder. The
horizontal spindle milling machine is in
tended for long and heavy cuts, such as
guide bars, connecting rods, key seat
ing, shaftinR, axles up to ten inches n
meter, etc. The heavy standard milling
machine is intended for general machine
shop use, but on larger work requiring
larger cutters and taking deeper cuts
than usually attempted on milling ma
chimes Of ts type.
The drilling and boring machines are OF
the horizontal type and are designed for
drilling. boring aud tapping great va
riety of work. These machines are all OF
high order or meri, according to the
Iron Ages expert. but their safety drill
aud tap holder specially warrants . de-
tailed description. The holder consists
of body with a taper shank to fit any
machine having revolving spindle,

receive soc set held between two pieces
of vulcanite fiber.
A cap is screwed on over the socket and
adjusted SO that there Is sufficient
strength to drive the tap. A drill socke
is held in the friction socket by pin and
is driven by feathers. the tap and its
socket ID held In the same manner. Tie
taps being held loosely they cannot cut
larger than themselves, aud being driven
by feathers, by feeding out and In them
selves they cannot cut or strip the thread
by careless hand feeding. On reaching
the bottom Of the hole the friction slips
and the danger Of breaking the tap is re-
duced to minimum. The change from
the drill to the tap socket can be instantly
made without stopping the machine.
New Button Machine.
Mr.. Isaac H. Sisson of this city has in.
