Improvements in Nut Locks.
1, WILLIAM ADOLPH BODE, of No. 246 Park Avenue, in City of Orange,
County of Essex, and State of New Jersey, United States of America, Inventor, do
hereby declare the nature of my invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
80
My invention relates to improvements in nut-locks, and has for its primary
object to provide a simple, cheap, durable and efficient means for securing and
adjusting nuts to axles of vehicles, machinery, etc., in which the parts are
connected and locked together as to prevent their independent rotation without
manipulating the locking devices, thereby providing a means which permits
of the easy detachment of the nut, without injury to the several parts of the
construction.
The invention therefore consists in the novel construction of nut-lock herein set
forth, and also in the novel arrangements and combinations of the several parts,
such as will be hereinafter fully described and finally embodied in the clauses of
the claim.
The invention is illustrated in the accompanying drawings, in which-
Figure 1 represents a longitudinal vertical section of the hub of the wheel of a
vehicle and a portion of the axle, illustrating the nut-lock in side elevation.
Figure 2 is a view of part of the axle, partly in elevation and partly in section,
illustrating in connection therewith, a vertical section of the several parts of the
nut-lock.
Figure 3 is an end view of the axle with the nut-lock in position thereon,
illustrating the arrangement of a check bolt and a pivotally arranged cap on the
axle-nut, adapted to be closed down over the head of the check bolt to prevent its
accidental displacement.
Figure 4 is a similar view of the axle and its nut, with said check bolt aud cap
removed.
Figure 5 is a view, similar to that illustrated in Figure 2, of an axle provided
with a nut-lock of a slightly modified form of construction, and Figure 6 is an end
view of the same.
Similar letters of reference are employed in all of the above described views, to
indicate like parts.
In said drawings, a indicates the nut which can be screwed upon the threaded
end of the axle arm of a vehicle, or any other well known form of journal, as
clearly indicated in Figures 1 and 2.
Said screw-threaded end 6 of the axle arm is provided with an internal bore 6*
which is formed at an angle of about 45 degrees to the longitudinal axis of the
axle-arm, substantially as shown in Figure 2.
The axle-nut a, which is of the usual form and construction on its sides a¹, has
one corner cut away to form the flat surface a³, which, when the nut is screwed in
place on the threaded end b¹ of the axle-arm b, comes directly above the angularly
arranged internal bore b³.
The said surface a² is provided with a hole a³, which is preferably oblong, as

page_text: shown in Figure 4, and which is brought directly 'äbove the open end of the bore b
when the nut a is screwed down upon the end 6 of the axle b.
The screw-threads in said bore 6 run in the same direction as the threads on the
part of the axle-arm, whereby both parts can be provided with right-handed
threads, which simplifies the construction.
As has been stated, the nut a is threaded internally to fit the threads of the
portion 6 of the axle-arm baud a check bolt c is provided which is passed through
the hole a in the flat surface a' of the nut a and is firmly screwed into said internal
bore until its head e' is securely brought down upon the said flat surface a³ of
the nut.
In this manner, the bolt e serves to check any possible and independent longitudinal
movement of the nut a upon the part &' during the rotation of the hub of the
wheel of the vehicle on its axle.
By this means the construction has been considerably simplified, since I can
dispense with the use of a bolt having a left-handed thread, for, owing to the
angular arrangement of the bolt c in the bore any longitudinal movement of
the nut is positively prevented, until the bolt c has been removed, and hence,
there can be no possible displacement by accident.
To avoid the possibility of the bolt c shaking loose, the surface a' of the nut a
may be formed with a recess a into which I have fitted on a pin d, arranged in the
holes or perforations a in said nut, as clearly indicated in dotted outline in
Figures 3 and 4, the perforated ears e¹ of an angular cap e, which is normally held
over the head c² of the bolt c by a suitable spring secured to the surface a of the
nut a by a screw or pin fl and having its end in operative holding contact
with the upper surface of said cap e, substantially as iliustrated in Figures 2
and 3.
Thus it will be seen, that when the cap e is closed
bolt c, any rotary movement of the same in the bore
positive nut-lock is the result.
down over the head c¹ of the
is completely checked and a
To remove the bolt c, the spring is turned to one side on its screw or pin",
and the cape can be thrown back in the manner of a hinge, thereby permitting
the use of a wrench on the head of the bolt c to unscrew the same.
In Figures 5 and 6, I have shown a slightly modified form of construction, in
which the internal bore is provided with threads of a different pitch to the
threads on the part 6' of the axle-arm b, said threads running in an opposite
direction to those on the part &', thus making one a right-hand and the other a
left-hand thread.
The nut a is provided with a recess a and a pin d¹ on which is pivotally
arranged an arm e to which is secured the cylindrical cap e. The forwardly and
downwardly projecting end of said arm e' is perforated and fits into a recess a³ in
the uut a in which it is held and secured by a pin d², as will be clearly understood
from an inspection of said Figures 5 and 6.
The cap is secured to the arm e* by means of rivets or screws e, but it can be
formed integral therewith or may be secured thereou in any other well known
manner.
When the arm is secured in its holding position on the nut u, the cylindrical
cap entirely surrounds the head c¹ of the bolt c, which in this case is concentric
with the outer circumference of the threaded part 1 of the axle-arm b, and said
cap thereby prevents any longitudinal movement of the bolt c, due to vibration of
the parts, when passing over rough roads, and the check bolt, c, in consequence,
prevents any independent longitudinal movement of the nut a.
In this manner a simply constructed and safe locking attachment to the nuts on
vehicles, machinery, and the like, has been devised; but it will be obvious that
the details of the arrangements and combinations of the parts may be changed or
modified, without departing from the scope of my invention, hence I do not wish to
be limited to the exact forms of construction herein shown.
The invention is also applicable to all forms of bolts and nuts.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination, with the threaded end of an axle, journal, or the like,.
having a screw-threaded bore, and a nut on said screw-threaded end, of a check
bolt in said bore, and a cap adapted to be closed down upon the head of said bolt
to entirely surround the same, said cap being pivotally secured to the face of the
nut, substantially as aud for the purposes set forth.
2. The combination, with the threaded end of an axle, journal, or the like,
having a screw-threaded bore 62, at an angle to the longitudinal axis of the axle, of
of a nut a on said screw-threaded end, having a chamfered surface a and a hole a*
corresponding with the open end of said bore 62, and a check bolt in said bore,
substantially as and for the purposes set forth.
3. The combination, with the threaded end of an axle, journal, or the like,
having a screw-threaded bore 63 at an angle to the longitudinal axis of the axle, of
a nut a on said screw-threaded end, having a chamfered surface a and a hole a'
corresponding with the open end of said bore 6', a check bolt in said bore, and an.
angular cap on said nut, adapted to be closed down upon the head of said bolt,
substantially as and for the purposes set forth.
4. The combination, with the threaded end of an axle, journal, or the like,
having a screw-threaded bore 6 at an angle to the longitudinal axis of the axle, of
a nut a on said screw-threaded end, having a chamfered surface a' and a hole a³
corresponding with the open end of said bore 63, a check bolt in said bore, a cap.
adapted to be closed down upon the head of said bolt to surround the same,
cap being pivotally secured to the face of the nut, and a spring fin engagement
with the face of said cap, substantially as and for the purposes set forth.
