WILLIAM T. MORRIS, OF WAXAHACHIE, TEXAS.
NUT-LOCK.1,261,592.
Specification of Letters Patent.
Patented Apr. 2,1918.
Application filed February 25, 1916. Serial No. 80,517.
To all whom it may concern:
Be it known that I, WILLIAM T. MoRRIS,
a citizen of the United States, residing at
Waxahachie, in the county of Ellis and
5 State of Texas, have invented new and use-
ful Improvements in Nut-Locks, of which
the following is a specification.
This invention relates to means for lock-
ing a nut upon a bolt, and an object of the
10 same is to provide a nut or washer with a
swinging hinged lock which may be remov-
ably secured to said nut or washer and which
when swung in one direction is brought into
contact with the threads of the bolt and
15 locked upon the nut or washer in such posi-
tion so as to effectively retain the nut locked
to the bolt against danger of unscrewing
from vibration or other accidental causes,
the construction being such that the locking
20 element may be readily brought out of en-
gagement with the bolt to permit of the un-
screwing of the nut or the removal of the
washer, when desired.
Another object of the invention is to pro-
25 vide a nut lock which shall be of a simple
construction, easily and quickly operated,
cheap to manufacture and which will per-
form the functions for which it is designed
with efficiency and with accuracy.
So With the above and other objects in view,
the improvement resides in the construction,
combination and arrangement of parts set
forth in the following specification and fall-
ing within the scope of the appended claims.

member for the nut disclosed in Fig. 19. 75
Referring now to the drawings in detail,
and to Figs. 1 to 6 thereof in particular, 1
designates the bolt upon which is screwed
a nut 2. The nut has its body portion of
the ordinary construction but is provided 80
upon its outer face and at one of its edges
with a flange 3 which is intersected by a
right angular lug 4 arranged upon the edge
of the lock which is disposed at an angle
to the edge upon which the flange 3 is 85
formed. The inner face of the flange is
formed with a longitudinally extending
rounded depression 5 which communicates
with the round opening 6 provided by a sub-
stantially key-hole slot 7 formed in the lug 90
4. The flange 3 is approximately centrally
formed with a transverse depression or open-
ing 8 and one or both of the side walls pro-
vided by the said opening, at the outer sur-
face of the flange is formed with an interned 95
rib 9. Also the face of the nut between the
side walls provided by the opening 8 may
be formed with a depression 10, and this de-
pression communicates with the threaded
bore of the nut 2. 100
The lock comprises a cross sectionally
round bar of some hardened metal, such as
harveyizecl or Krupp steel, and the same has
one of its ends slitted longitudinally, as at
12, and provided upon one of its faces with 105
a flat surface 13. This end of the bar 11 is
adapted to be received within the key hole
slot in the lug 4, while the body of the said
bar is arranged within the depression 5 in
the flange 3 and is adapted to frictionally 110
contact with the wall provided by the said
depression in a manner which will presently
