WILLIAM E. BOREN, OF LAKEVIEW, TEXAS.
NUT-LOCK.Specification of Letters Patent. Patented Feb. 16, 1915.
Application filed April 9, 1913. Serial No. 759,985.To all whom it may concern:
Be it known that I, WILLIAM E. BOREN,
a citizen of United States, residing at Lake-
view, in the county of Hall, State of Texas,
5 have invented certain new and useful Im-
provements in Nut-Locks; 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
10 it appertains to make and use the same.
The present invention is directed to im-
provements in nut locks, and has for its
object to so construct a device of this char-
acter that a nut can be easily applied to
15 the bolt or removed therefrom, and when in
place thereon will be held against accidental
rotation in respect to the bolt.
A further object of the invention is to
provide a nut lock which is exceedingly sim-
20 ple, effective in operation, and one which
may be manufactured at a minimum cost.
With these and other objects in view, this
invention resides in the novel features of
construction, formation, combination and
25 arrangement of parts to be hereinafter more
fully described, claimed and illustrated in
the accompanying drawing, in which
Figure 1 is a side elevation of the device.
Fig. 2 is a top plan view. Fig. 3 is a sec-
30 tional view on line 3-3 of Fig. 1. Fig. 4
is a longitudinal sectional view through the
device.
Referring to the drawing, the numeral 1
designates a bolt having formed therein
35 longitudinal V-shaped grooves 2. Adapted
for engagement with the bolt 1 is a nut 3,the same being preferably rectangular in
shape and has formed therein radial grooves
4, the outer ends of which open at the cor-
ners of the nut. After the nut has been 40
properly positioned upon the bolt key plates
5 are placed in the grooves 4 with their bev-
eled ends 6 engaged in the grooves 2 formed
in the bolt, thereby preventing said nut
from rotating. Each key plate 5 is formed 45
with a perforation 7 which registers with
the obliquely disposed bores 8 formed in the
nut 2, and in which are inserted pins 9,
which also pass through the perforations 7
formed in the key plates 5, thereby prevent- 50
ing accidental removal of said plates.
From the foregoing description, it will
be seen that a nut lock has been produced
which can be easily applied to the bolt, and
firmly locked against accidental displace- 55
meant therefrom.
What is claimed is:-
In combination, a nut adapted to engage
the end of a bolt, the said nut having ra-
dially extending slots therein, key plates re- 60
movably mounted in said slots and adapted
to extend into the said bolt, tapered holes
intersecting said slots, and tapered pins in-
serted through said holes so as to pass
through the key plates to maintain the same 65
in position.
In testimony whereof, I affix my signa-
ture, in the presence of two witnesses.
WILLIAM E. BOREN.
