pointt where the explosion is to take place.
When all is ready, the dart pipe or go-devil
is released, and when it strikes the firing
pin, the primer is exploded, exploding the
6 fulminate 14 and the charge of nitro-
glycerin.
The advantages of this invention.lie in
the safety with which it may be handled,
the simplicity of its construction and its
Lo cheapness of manufacture. While I have
described a form of my invention which I
believe to be particularly effective, I wish it
understood that many changes may be made
in the details thereof, without departing
15 from the spirit of the invention., as defined
in the appended claims.
I claim:-
.1. A well torpedo comprising an explo-
sive container, a detonating head detach-
20 ably connected to the container, and having
therein a fulminate chamber and a primer'
seat, a firing pin slidably mounted in the
detonating head above the primer seat,.
means for sustaining the firing pin in a
26 safety position, and means fqr detachably
connecting a wire to the detonating head.
2. A well torpedo including an explosive
container, a detonating head having a ful-
minate chamber and a primer seat, the head.
30 above the primer seat being formed to pro7
vide an arched yoke, a bolt detachably en-
gaged with the upper end of the yoke and
extended transversely thereof and adapted
to be connected to a supporting wire, a fir-
a ing pin guided in the yoke, and slotted to
,accommodate said bolt and disposed con-centric to the wire when the wire is in place,
and means on the, yoke for engaging the fir-
ing pin and holding it raised.
3. A well torpedo including a tubular ex-
plosive container closed at its lower end and
having screw-threads at its upper end, a
detonating head having a chamber at its
lower end for containing fulminate and con-
nected by a coupling to the explosive con-
tainer; there being a primer seat above the
'fulminate chamber and the upper portion
of the detonating head being formed to pro-
vide an upwardly arching yoke, the yoke
being formed with a medially disposed cross
bar, the upper end of the yoke and the cross
bar being both perforated, a bolt. passing
transversely across the upper end of the
yoke, a firing pin slidably mounted in the
perforation of the yoke and coacting with
the primer seat, the upper end of the firing
pin being vertically slotted, said bolt pass-
ing through the slot, a set screw passing
through the lower cross bar of the yoke and
engaging the firing pin to hold it in its
raised position, a lowering wire connected
to the bolt, and a dart pipe loosely surround-
ing the wire-and adapted to engage the up-
per end of the firing pin when the dart pipe
is dropped.
In testimony whereof I hereunto affix my
signature in the presence of two witnesses.
