Improvements in and relating to Nut Locks.
We MURRAY CUSTIS SLUSSER, Farmer, and WILLIAM JACOB SLUSSER,
Blacksmith, citizens of the United States of America, and both residing at Slusser,
in the County of Montgomery, and State of Virginia, one of the United States of
America, do hereby declare the nature of this invention, and in what manner the
same is to be performed, to be particularly described in and by the following
statement:-
This invention has relation to improvements in nut locks, and it consists in
the novel construction, arrangement, and combination of parts of which it is
composed, all as will be hereinafter fully described.
The annexed drawings, to which reference is made, fully illustrate our invention,
in which-
Figure 1 represents a side view of a bolt and nut showing our improvement
attached.
Figure 2 is a front or face view of the same.
Figure 3 is a vertical longitudinal sectional view.
Figure 4 is a transverse sectional view taken on line x of Figure 1.
Figure 5 is a front view showing our device in modified form.
Figure 6 is a perspective view of our improved nut lock key.
Figure 7 is a front view partly in section of a modification."
Figure 8 is a similar view of another modification.
Figure 9 is a perspective view of the locking pin in modified form, and
Figure 10 is a side view of the hand bar.
Referring by letter to the accompanying drawings, A. designates a headed bolt,
the threaded end a of which is flattened on one side as at b. B represents the nut
having the usual female screw thread c, which engage the male thread on the bolt ;
said nut is provided with a recess d on its outer face in which is fitted snugly a
plate e the lower edge of which is provided with a V-shaped notch f, that receives
a correspondingly shaped pin g, which latter is flat on one side as at h and engages
the flat surface of the bolt.
This locking pin is provided with lip portion i designed to receive the end k of
the releasing or unlocking hand bar / shown in Figure 10 of the drawing.
It will be seen that in locking the nut to the bolt, said nut is screwed up, after
which the plate is inserted into the recess opposite to the flat surface of the bolt,
when the locking pin is forced or driven in between the plate and bolt, thus when
so engaged said nut or bolt is prevented from turning, thereby preventing accidental
displacement of the nut.
When it is desired to remove the nut from the bolt, the operator simply presses
the pin outwardly with the hand lever, the end k of which engages the lip on the
locking pin.
In Figure 5 our device is shown in modified form, wherein the inner face of the
recess is roughened as at m and the outer face edge of the plate is correspondingly
roughened to engage said plate, as shown, to prevent the plate from turning
independently of the uut. In the modification shown in Figure 8 the locking pin
has double bevelled sides, as shown at n, the plate and bolt each having V-shaped
grooves o o, in which said pin is inserted.
The plate may also be slightly modified, as shown in Figure 7, the same having
the ends p p extended on either side of the bolt.
A nut lock as herein described is durable, the nut not liable to become
accidentally displaced. and chean to manufacture.

page_text: Having now particula ly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :
1. In a nut lock, in combination with a bolt having a flattened face, a nut having
a recess in its face, a plate inserted therein, and a key for locking said plate to the
bolt, substantially as described.
2. In a nut lock, the combination with the bolt having a flattened surface and a
nut having a recess in its face, of the plate adapted to seat in the recess and
provided with the V-groove and the locking pin having the bevelled portions and
lip, all substantially as described.
Dated this 30th day of January 1894.
