HACK SAWS.
And Saws of Various other Sorts
Used In Cutting Metals.

Used In Cutting Metals.
No doubt the common idea OF a saw
would be OF an implement used for
saving wood. and such is the chief
use TO which saws are put; but there
are also many saws used for saving
metals. The most commonly used OF
these saws is what is called a hack
saw.
The hack saw is built something like
meat saw; that is. the blade is held
between the bent down ends OF a
frame 10 one end OF which is attached
the handle by which. in the ordinary
way. the saw is piled. But the hack
saw is smaller than the meat saw. with
a far more slender frame, and n light,
slender blade.
There are various styles and sizes OF
hack saw frames. including extension
frames, in which can be used. accord
ing as the frame is adjusted. saws OF
different lengths; for the hack saw
blade is not riveted into its frame. but
adjusted there. and blades can be taken
out or put in At viii.
The blades are very narrow and very
thin and very fine toOthcd: they are
made of steel specially hardened for
the use. In the manufacture OF the
blades the teeth are set and filed by
machines with greater accuracy than
that work could be done by hand. and
at much less cost. Formerly many
hack saw blades were imported from
England; now there are very few i'm
ported. The American blades are bet
ter and far cheaper. They are SO mex
pensive that when worn dull they are
not rehled; il is cheaper TO use a new
blade
The hack saw blades most commonly
used are made In various lengths rang
ing from TO Is inches; perhaps there
are sold more Is inch blades than any
other These saw blades are put up
in dozens, dozen Of them together
making only slender little bundle.
The average price at retail is about 65
cents dozen.
Hack saws are used in many trades.
y jeweler would have some little hack
saws on his work bench; hack saws
are used by machiniStS, lOckSmiths.
stovemakers. plumbers. brass workers.
foundrymen; they are used in all
trades in which metals are work ed.
and the carpenter. supposed to be a
worker in wood alone. is likely TO have
a hack saw in his Kit of tools He may
want TO saw of a bolt or something
of that sort. and for that matter hack
saws are sometimes used for saving
in wood.
How long hack saw will last de-
pends. OF course. very largely on how
much ii is used. but n hack saw with
which seven inch steel shaft had
been cut of still remained sharp
enough for further use. Hack saws are
put 10 many uses on indoor and on ont
door work
There are now made for railroad con
structiop and repair work portable rau
saws for saving on rails, the old wav
being to cut them off with chiSel and
hammer. The rail is clamped into the
frame in which the saw is worked. the
saw being operated by hand power.
portable rail saws of American inven-
ton and manufacture are sold all over
the world
OF power driven saws for metals
there are various kinds. these saws be-
Ing put 10 many uses. For some pur-
poses hack saws are fitted up SO that
they can be power driven, but the saws
commonly used with power are cir
cular. AS To size. circular saws are
made for metals ranging from IN go
inches in diameter. and such saws are
variously tempered. some harder and
some softer. according TO the use TO
winch they are 10 be put some are
run at high speed. some at low speed.
Some are toothed and some are tooth
less. these last being called friction
saws. And there are cold saws and
not saws. so called. the hot saws being
used 10 saw metal which comes 10 the
saws redhot.
Such saws. in one form and another.
are used in the various mills in which
iron and steel are made INTO shapes
and In bridge and architectural works
ana III machine shops and foundries;
they are used for saving of rails and
beams and bars and for many other
! purposes.-Ncw York sun.
