reliable under all conditions and can be
readily applied and, if desired, may be
withdrawn or may be made permanent by
the simple operation of cutting off the head
5 which renders it inaccessible with ordinary
manipulation. This locking means may
also be used in many places where it is diffi-
cult or impossible to insert rivets, providing
wherever used all the advantages of a cold
10 rivet when the head of the key is removed
or cut off besides making removal or tight-
ening up easy when the head of the key is
not removed. The key may also be used
with positive results in places of great im-
15 portance, such as on connecting rod bolts
and nuts. As minor modifications are con-
templated I do not wish to be limited to
the exact details as shown and described
except as defined by the appended claims.
20 Having thus described the invention what
is claimed as new is:
1. The combination of a nut and a bolt
having coperating grooves adapted to form
a keyway, the groove in the nut extending
25 only part way therethrough and being
deeper at its inner end, and a key fitting
in the keyway, the end wall of the groove
in the nut blocking the keyway so that said
key will have a part thereof bent into said
30 deeper part and a part bent into engagement
with said bolt when the key is forced into the
keyway.
2. The combination of a nut and a bolt
having coperating grooves adapted to form
35 a keyway, a key fitting the keyway, and
means whereby the key on insertion into
the keyway is locked therein and bent upon
itself to produce a thickened portion at the
end of the key to wedge the parts together.
40 3. The combination of a nut and a bolt
having coperating grooves adapted to form
a keyway, the groove in the nut varying
in depth and passing only part way there-
through leaving a portion of the nut ex-
45 tending across the keyway, a key fitting the
keyway and weakened intermediate its ends
so that when it is driven into the keyway
and engages the said portion of the nut ex-
tending across the keyway it will bend and
50 part of the key will be forced into the deeper
part of the groove in the nut and the end
of the key will be forced into engagement
with the bottom of the groove in the bolt to
lock the nut and bolt together.
55 4. The combination of a nut and a bolthaving cooperating grooves adapted to form
a keyway, the groove in the nut passing only
part way through the opening in the nut
and being deeper at its inner end forming
a cavity therein, a key fitting the keyway 60
and weakened intermediate its ends, a
thread of the nut extending across and
blocking the keyway at the inner end there-
of, said key having a part which limits its
inward movement when the key is forced 65
into the keyway and bends at its weakened
portion sufficiently to fill the cavity and lock
the key in the keyway.
5. The combination of an internally
threaded nut and a threaded bolt having 70
grooves adapted to coperate to form a key-
way, the groove in the nut being deeper and
forming a locking cavity at its inner end,
and extending only part way through the
nut leaving threads extending across the 75
keyway, a key fitting the keyway and hav-
ing a weakened section near one end, said
key when forced into said keyway being
adapted to engage said threads and bent
at the weakened section so as to curl the end 80
and force a part of the key into said cavity
and the end of the key into engagement
with the bottom of said groove in the bolt.
6. The combination of a nut and a bolt
having cooperating grooves adapted to form 85
a keyway, the groove in the nut having a
cavity joined thereto by a rounded shoul-
der, a key fitting the keyway and having
a weakened section intermediate its ends,
a thread of the nut extending across the 90
keyway and adapted to deflect the end of
the said key and bend a part thereof up-
wardly to fill the cavity and a part against
the bottom of the groove in the bolt where-
by any looseness of fit or slack in the threads 95
on the opposite side of the nut and bolt is
removed to securely key the nut and bolt
together, means limiting the inward move-
ment of the key and means whereby the key
may be withdrawn, said rounded shoulder 100
being adapted to restore the key to its origi-
nal form as it is withdrawn from the key-
way.
In testimony whereof I affix my signature
in presence of two witnesses.
