ana Snwn OF Various Other Sorts
Used In Cutting Metuls
No doubt the common idea of n 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 Il hack
saw.
The hack saw Is built something like
meat saw: that is, the blade 10 held
between the bent down ends Of
frame, to 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
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 rivctcd into It's frame. but
adjusted there, and blades can be taken
out or put IN ut will.
The blades are very narrow and very
thin and very fine toothed they are
made of Il steel specially hardened for
the usc. IL the manufacture OF tho
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 anu Tar cheaper They arc so incx-
nSfx
not relied; 1t is cheaper to use new
blade
| The hack saw blades most commonly
used are made in various lengths rang
ing from to II inches; perhaps there
are sold more IS inch blades than any
other These saw blades nrc put up
In dozens. n dozen OF them together
making only Il slender little bundle.
The average price Mt retail is about Oj
cents dozen.
| Hack saws are used In many trades.
a jeweler would have some little hack
saws on his workbench; hack saws
are used by mnchlnists, locksmiths,
stovemakers. plumbers. brass workers,
rOundrymen; they are used In all
trades In which metals are worked,
and the carpenter, supposed to be q
worker IN wood alone. is likely to have
hack saw in his kit OF tools. He may
want to saw Off n bolt or something
Of that sort. and for that matter hack
saws are sometimes used for saving
in wood.
| How long Il hack saw will last de-
pends. of course. very largely on how
much it is used. but hack saw with
IvyI, ,Jn1,
been cut off still remained sharr
enough for further use. Hack saws arc
put to many uses on indoor and on out
door work.
| There are now made for railrond con-
struction and repair work portable rail
saws for saving Off rails, the old way
being to cut them Off with chisel and
hammer. The rGil Is clamped into tho
frame IN which the saw is worked, tho
saw being; operated by hand power.
Portable rnil saws Of American inven.
| tion and manufacture are sold all over
the world.
| or power driven saws for metals
! there are various kinds. these saws be-
ing put to 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
culnr. AS to size, circular saws are
made for metals ranging from to 60
inches In diameter, and such saws are
var.ousiy tempered. soEc harder and
some softer. according to the use to
|hich they are to be put. Some are
run ut high speed, some ut low speed.
Some are toothed and some are tooth.
less. these last being called friction
saws. And there are cold saws and
hot saws. SO called, the hot saws being
used TO saw metal which comes to 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
and III machine shops and foundries;
they are used FOR saving of rails and
beams and bars and for many other
purposes.-New York Sun.
