WILLIAM B. MILLARD, OF CLEBURNE, TEXAS.
NUT-LOCK.Speciication of Letters Patent.. Patented Feb. 22,1916.
Application fled June 5, 1914. Serial No. 843,153.To all whom it may concern:
Be it known that I. WILLIAM R. MIrAmRD,
a citizen of the United States, residing at
Cleburne, in the county of Johnson and
5 State of Texas, -have invented a new and
useful Nut-Lock; and I do hereby declare
the following to be. a full, clear, and exact
description of the invention, such as will
enable others skilled in the art to which it
10 appertains to make and use the-same.
This invention relates to a new and use-.
ful nut lock, and the object in view .is to
provide a simple and efficient nut lock hav-
ing improved features of construction.
15 One of the features of construction is the,
provision of a spring coil constructed from
a single length of spring wire material, the
opposite ends of the wire material extend
laterally and provided with a return bent.
20 portion, forming arms. The spring coils
are designed to fit tightly and frictionally
the threads of the bolt, and by pressing said.
arms toward one another, said coils may be
expanded, so that the device may be par-
25 tally rotated in one direction or the other.
The arms are provided with inter-engaging
locking means toehold the arms together, so.
that the device may be unscrewed from the
threads of the bolt.
0 In practical fields the details of construc-
tidn may necessitate alterations, falling
within the scope of what is claimed.
The invention comprises further features
and combination of parts, as hereinafter set
35 forth, shown in the drawings and claimed.
In the drawings:-Figure 1 is a view in
perspective showing the improved nut lock-
ing device.as applied. Fig. 2 is a plan view
showing two of the nut locking devices em-
40 ployed. Fig. 3 is an enlarged detail view of
the device. Fig. -4 is a perspective view
illustrating another form of construction.
Referring more especially to the draw-
ings, 1 designates the bolt having the usual
45 form of nut 2..
The nut locking device comprises a single
length of spring wire constructed to-form a
spring coil 3, designed to engage the threads
of the shank of the bolt. The opposite ends
50 of the spring wire material terminate in lat-eral extending portions 4 provided with a
return bent portion 5, thereby forming arms,
to be grasped by the fingers to pull the arms
together, whereby the coils may be expanded
for detaching the nut locking, device. When 55
said arms are brought together, they are
locked in such positions by the hooks 8, en-.
gaging the lateral extending portions 4. In
Fig. 2 there are two nut locking devices
employed, one upon each side of said nut, 60
both of which act together to lock the nut in
position.
The invention having been set forth, what
is claimed as new and useful is:
1. A nut lock device comprising a single 65
length- of wire material constructed to form
a spring coil having several convolutions,
the end portions of the material beyond the
coil being formed into loops, one arm of
each loop at its extremity terminating in a 70
hook, each hook extending toward and be-
ing substantially opposite the other arm of
each loop and being designed to engage said
other arm, thereby holding the loops pressed
toward each other for expanding the coil 75
whereby the same may be detached from a
bolt shank.
2. A nut lock device- comprising a single
length of wire material constructed to form
a spring coil having several convolutions, 80
the end portions of the end convolutions of
the coil being extended substantially tan-
gentially to the coil forming substantially
triangular shaped loops, the extremity of
one arm of each of said loops having a 85
hook extending toward the opposite arm of
said loop, said hooks designed to engage
diagonally opposite arms of the opposite
loops to hold the loops pressed together,
thereby holding the convolutions of the 90
coil expanded, whereby the coil may be
easily detached from the bolt shank.
In testimony whereof I have signed my
name to .this specification in the presence of
two subscribing witnesses.
WILLIAM R. MILLARD.
