'1l-hef:presentvv invention relates to new- and use
improvements in. saw sets' of' a,> type as cov
ered. in; my prior U.. S.. Letters Patent No.
$141,695', dated. lllecernber‘Z’lv, 1938'.V
An importantv object of the present invention
is to~ provide a saw set of: the-` aforementioned
character in which a tooth-setting jaw is pro~
vided having anA elongatedI head adapted to con"
tact the beveled side; of. the tooth. for' exerting
pressurey thereon during the saw setting` action.,
the head of the.` saw setting jaw being adapted
fon use with fine. or' coarse. saw teeth and em.
b‘odying means: for adjusting the.: head of; the set’
ting jaw in` accordance witlrtha character of the
tooth being set.-
A further object of the present» invention is
to provide a springeactuated Wedge adapted to
grip the side of the saw for holding the same
ñrmly while the teeth are being set.
A further object“l of the invention is to provide
the section 2 and the section-2 has a ilat upper
end disposed in abutting relation with the shoul
der 5,_ aswell as a fiat inner face 6» for disposal
in'face-to-face Contact with the ilat inner tace
‘I of the section> I.
The sections»3 I1 and 2 are detachably secured
to each other‘by: a bolt `8` which extends through
the section I and is threaded in the section 2..v
The lower" portions of each of the sections," are
10 reduced. and provided> with flat confronting-faces
disposed in spaced-apart' relation- with respect to
each other for receiving a- saw- blade 9' between
the' same and the opposed face of. the section- I
has ar recess I-Ilf formed therein and in whichl is
slidably mounted a wedge block. Ict yieldably
urged; downwardly toward. the lower end. of.Y the
section. I` by a coil spring I-2 toset.- up frictional
wedging action against the saw blade.
The inner portion of the spaced confronting
faces of the sections are formed with registering
a device of this character of simple and prac
~recesses I3 and I4, respectively, the recess I3 hav

The section I vis relatively longer than the sec
tion 2, the section I tapering toward its upper r
end, as indicated at 3, and terminates in a ñat
surface to provide a striking head 4 to receive a

brought into contacting engagement with the 10 inner faces to receive a saw blade therebetween
and a saw tooth receiving chamber at the inner
teeth of the saw in accordance with the size of
the teeth being set.
It is thought from the foregoing description
that the advantages and manner of operation
of the device will be readily apparent to those
skilled in the art.
It is to be understood that' changes'~ may be»
made in the construction and in the arrangement
of the several parts as herein described and i1'
lustrated in the accompanying drawing, provided 20
that such changes fall> within the scope of the
ends of said faces, a tooth engaging jaw embody
ing an elongated head mounted for lateral move
ment within said chamber, an anvil mounted for
lateral movement within said chamber and co
operating with said jaw, means for adjustably
moving said jaw toward and from said anvil, and
means for adjustably moving said anvil toward
and from said jaw.
