ING WE'LL TOoLs.-A day or two ago we
noticed that our townsman, Mr.. James II.
Luther, had invented and secured q patent
for an improvement 10 q Jsr.Grab for ex.
| tracing and taking out broken and lost
tools from artesian or oil wells, or other
holes drilled in rocks, &c. As the inven-
tion Is one Of the most important and use
ful ever made, we append description Of
the tool, which will no doubt prove Of In
terest to our oil men: "My invention re-
lates to class of tools known as grabs, and
used for extracting broken tools, &C., from
oil and artesisn welIs- and 1t consists 10 tie
form and construction of the socket head,
with deep grooves In both sides, and tho ODE
long interior socket, through which one or
more transverse bolts may be put TO streng,
then II when the nature of the
tool to be extracted will admit of II. 1t
also consists in providing and securingwitht
iu the socket .wo or more pairs of serrated
nippers, wedge-shaped, and rounded oa the
back, fitting in corresponding grooves In
the socket to slide up and down, their tops
being connected together BY screw-bolt
extending up through the socket'head TO
slide with the nippers. The shsuks above
the serrated portions Of the nippers, being
made spring temper, will yield enough to
grsppls jar-link or fasten to the piece to
be extracted from the hole or we'll.
To enable others to make aud use my iw>
proved '.jarssrab, WILL describe 1t more
fully:
The stock or body Of the tool or implem. Mt
10 made OF such size that the two round.
ed edges will nearly ill the diameter Of the
hole or we'll in whic, It is used, tie upper
end being formed into shank, having q
shoulder, and strong sclew-tbread, with
which to connect 1t with the fixtures above
tor working il. The two Hat sides OF the
stock have deep Central groove, fared out
at the bottom. The heads and nuts of the
trans serse bolts are Sc sted in the groove and
are thereby prevented from coming in con-
tact with the sides OF the we'll. The stock
on its edge is provided with an oblong openI
ing, extending up half Its length or more. IT
desired. The stock Is hollow from its lower
10 high as the upper end Of the opening thus
forming socket to hold the graphing nip
pers aud receive . portion OF tue broken
link or other object TO be grsppled. Near
sides, are rounded tapering recesses into
which are fitted the backs of The serrated
jaws which form the spring sliding nippers.

screw bolts which are provided with beads

tools or fixtures which are liable to become

drilling or a:.wel: :wbie boring. Zone or more
bolts, may bs put transversely through the
stock, which, when 10, will aid tn insure the
graphing OF broken links when the fork Is
up, and other smaller objects, such as butts.

and will also strengthen the socket while
jarrinR. The bolts must be removed vhea |
the object to be grsppled IL Of such size or
figure that 1t will net enter the svcket when |
said bolt is present
The nippsrs are, preferably, made sepa-
rate, the upper end Of one of the springs
being thickensd to form o suitable mutt for
tho reception Of the screw end of the bolt.
