forming an angular continuation of the
flange 45. The flange is provided with a
longitudinally extending curved depression
47, which communicates with a key hole
5 opening 48 in the lug 46. The flange is
approximately centrally provided with a cut-
away portion or opening 47, and one or both
of the transverse walls provided by the open-
ing are formed with ribs 15 at the outer edges
10 thereof.
The lock includes a bar 51 which is round
in cross section and which has one of its
ends split, as at 52, and one of the faces
thereof flat, as at 53. The bar is provided
15 approximately centrally thereof with an an-
gular arm forming a lever 54, the said lever
being swung between the walls provided by
the opening 49 when the device is in opera-
tive position. The wall or surface of the
20 washer 44 central and forward of the open-
ing 49 is provided with a depression 56 to
receive the cutter when the same is arranged
flush with the inner straight wall of the
flange 45 and is in its in-active position.
25 The flat end of the bar is inserted in the
key hole opening 48 of the lug 46, and when
the same is swung to active position, a suit-
able instrument is inserted within the slit
so that this end of the bar sufficiently fills
30 and contacts with the walls provided by the
said key hole opening. This action also
forces the bar longitudinally in one direc-
tion to bring one of the edges of the same
into contact with one of the walls provided
35 by the opening 49 and its face into engage-
ment with one of the ribs 50 provided by
the same.
From the above description, taken in con-
nection with the accompanying drawings,
40 the simplicity of the device, as well as the
advantages thereof will, it is thought, be
perfectly apparent to those skilled in the art
to which such invention appertains without
further detailed description.
45 Having thus described the invention, what
I claim is:
1. In a means for locking a nut on a bolt,
a substantially square or rectangular ele-
ment having a central opening receiving the
50 shank of the bolt, said element being chan-
neled from one of its sides in a line with its
other side for approximately one-half of the
length thereof, and the outer wall of thea
channel providing a flange, said flange hav-
ing a transverse opening at the terminal of 55
the channel, the side of the element from
which the channel enters, having a depres-
sion, the inner wall of which being irregu-
lar, a locking bar comprising a substantially
right angular member having one of its 60
limbs received in the channel and the other
limb received in the depression designed to
frictionally engage with the inner wall pro-
vided by the said depression, the first men-
tioned limb being provided adjacent its ends 65
with an outturned portion forming a lever
designed to be received in the referred to
opening in the flange and having its oppo-
site face provided with a cutting member
designed to enter the bore of the said square 70
or rectangular member and to engage with
the threads of the bolt.
2. In a device for the purpose set forth,
the combination with a bolt and a nut
screwed on said bolt, said nut, from one of 75
its sides and upon its outer face being chan-
neled longitudinally for approximately one-
half the length of the nut, the outer wall
of the channel providing a flange, and the
said flange having an opening from the side 80
of the nut, the nut having a passage ar-
ranged in a line with the inner wall of the
channel, and also having an opening dis-
posed opposite the first mentioned opening
and communicating with the bore of the 85
nut, the side of the nut from which the chan-
nel enters having a longitudinal depression,
the inner wall of which being irregular, a
shoulder upon the outer face of the nut over-
lying a portion of the depression, a locking 90
bar received in the channel and in the pas-
sage, said bar having an offset portion re-
ceived in the opening of the flange and hav-
ing a cutting surface designed to enter the
bore of the nut to engage with the threads 95
of the bolt, said bar having an outer angu-
lar end received in the referred to depres-
sion in the nut, and frictionally contacting
with the inner wall of the said depression,
and underlying the referred to shoulder. 100
In testimony whereof I affix my signature
in presence of two witnesses.
