WILLIAM REID COLLIER, OF AUSTIN, TEXAS.
LOCK-NUT.Specification of Letters Patent.
Patented June 6,1916.
Application filed May 4, 1915. Serial No. 25,768.
To all whom it may concern:
Be it known that I, WILLIAM REID COL-
LIER, a citizen of the United States, resid-
ing at Austin, in the county of Travis and
* State of Texas, have invented a new and use-
ful Lock-Nut, of which the following is a
specification.
This invention relates to locking bolts and
nuts and more particularly .to that type in
10 which a relatively soft metal is employed
as the locking medium.
An object of the'invention is to provide a
novel locking means in which the compo-
nent members coperate to insure a positive
15 locking action which will not impair the
strength of the device.
A further object of the invention is to
provide a locking bolt and nut of generally
improved construction whereby the de-
20 vice will be simple, durable and inexpensive
in construction, as well as convenient, prac-
tical, serviceable and efficient in its use.
With the foregoing and other objects in
view which will appear as the description
25 proceeds, the invention resides in the combi-
nation and arrangement of parts and in the
details of construction hereinafter described
and claimed, it being understood that
changes in the precise embodiment of the
30 invention herein disclosed can be made
within the scope of what is claimed without
departing from the spirit of the invention.
The invention has been illustrated in its
preferred embodiment in the accompanying
35 drawings, wherein:-
Figure 1 is a longitudinal sectional view
of the invention with the component mem-
bers in their unlocked condition; Fig. 2 is a
similar view but depicting the component
40 members in their locked condition; Fig. .3
is a transverse sectional view of the inven-
tion taken on the line 3-3 of Fig. 2; and
Fig. 4 is a perspective view of the locking
nut before the soft locking metal has been
45 applied thereto.
In carrying out the invention there is
provided a bolt 1 which has one end thereof
threaded, as indicated at 2. A plurality of
longitudinal slots 3, of predetermined
50 lengths, are formed in the threaded end of
the bolt 1, which slots are approximately V-
shaped in cross section and have a radial
wall 4 and a wall 5 which is almost per-
pendicular to the wall 4.
55 In order to provide a positive and prac-
tical locking means, there is provided a nut6 having an axial threaded bore 7 which
communicates with a non-circular axial re-
cess 8, that is formed in the outer end of
the nut 6, for the reception of a soft lock 60
ing element or bushing 9. This locking ele-
ment 9 may be formed of any suitable soft
malleable metal such as lead, Babbitt metal
and the like. . The member 9 has an axial
threaded bore 10 which corresponds to and 65
communicates with the threaded bore 7,
while the periphery of the locking member
9 is non-circular, as indicated at 11, to con-
form and adhere to the non-circular recess
8, which extends into the nut for approxi- 70
mately one-third of its axial dimension.
To insure the maximum strength for this
device, it is employed most advantageously in
connection with structures.of known dimen-
sions, which permits an accurate predeter- 75
mination of the length of the slots 3, so that
the length of the slots 3 approximate the
axial dimensions of the soft locking member
9. Therefore, by this arragnement the
greater part of the axial bore 7 of the nut 6 80
is in uninterrupted threaded engagement
with the threaded end 2 of the bolt 1.
In the practical employment of this de-
vice the bolt 1 is placed within suitable aper-
tures that are formed in the material M 85
which is to be secured by this device, after
which the nut 6, with its soft locking mem-
ber 9, is screwed upon the threaded end of
the bolt 1 until the desired tension is ex-
erted upon the material M. It will be ob-' 90
served that the inner end of the slot 3 ter-
minates approximately in the same trans-
verse plane as the inner axial terminal of
the locking member 9, so that the portion of
the threaded bore 7 of the nut 6 that lies be- 95
tween the inner axial terminal of locking
member 9 and the inner face of the nut 6, is
in uninterrupted threaded engagement with
the bolt 1, while the soft locking member 9
threadily engages the outer end of the bolt 100
1. The peripheral continuity of this thread-
ed engagement, however, is interrupted at
predetermined intervals by the longitudinal
radial slots 3.
To lock the nut 6 upon the bolt 1, the 105
outer or projecting portion of the member 9
is hammered or forced into the slots 3, by
any suitable means, until the outer face of
the member 9 is even or flush with the outer
face of the nut 6. Now the nut 6 is securely 110
locked upon the bolt 1, as indicated in Figs.
2 and 3, so that any movement of these1,185,77s2.
