I, JUDSON WYCKLIFF HIMES, Inventor, of Elma, State of Washington, U.SA,
do hereby declare the nature of this invention to be as follows
This invention relates to improvements in nut locks, and the object thereof
18 to provide a simple, cheap and effective construction of nut-lock, for locking
the nut upon the bolt and preventing the accidental displacement thereof
The invention comprises a locking washer which 18 slit inwardly from its
edge and radially from its centie forming a plurality of locking tougues The
slits do not extend entirely to the central opening, but terminate short thereof.
The central opening in the washer 18 formed with inwardly projecting tongues
which, when the bolt 18 in place with the washer upon it, are bent outwardly
into the bolt opening-which is provided with notches to receive them of the
article against which the nut is adjusted. When the latter is a fish plate, the
opening is usually oblong, and there 18 sufficient 100m for the tongues to enter it
These tongues prevent the rotation of the washer After the nut has been
properly adjusted, one of the locking tongues of the washer 18 bent forwardly
to overlap one of the faces of the nut and thus prevent rotation thereof.
When the locking washer 18 used between two nuts, one of the locking tongues
is bent in one direction to engage one nut, and another tongue in the opposite
direction to engage the other nut In this case, the tongues in the cential open-
ing of the washer are not necessary
Should the object against which the washer is to bear be of wood, the washer
has the central opening in it slit at its edges in such manner as to form tongues
which can be bent outwards to enter the surface of the wood and
prevent rotation
of the washer The nut is prevented from 1otating by the locking-tongues as
aforedescribed
In a modified form of the invention, each locking tongue of the washer is
formed with a radial corrugation which permits of a round pointed tool being
placed between it and the fish plate or other article to bend the tongue over
In another form of the invention, the bolt is longitudinally slotted to receive
the tongues in the cential opening of the washer thus locking the bolt and
washer together
The washer may be made in any desired shape as, for instance, square or
oblong.

do hereby declare the nature of this invention, and in what manner the same 18
to be performed to be particularly described and ascertained in and by the follow-
ing statement
-
This invention relates to improvements in nut locks, and the object thereof
is to provide a simple, cheap and effective construction of nut-lock, for locking
the nut upon the bolt and preventing the accidental displacement thereof
With the above object in view, the invention consists in the novel details of
construction hereinafter fully set forth in the specification, particularly pointed
out in the claim, and clearly illustrated by the accompanying drawings, in
which:-
Figure 1 is a front elevation of a nut and bolt having my improved nut lock
applied thereto Fig 2 is a longitudinal sectional view of the same. Fig. 3 is
a plan view of the washer, constituting the nut-lock. Fig. 4 is a vertical, longi-
tudinal, sectional view shewing the nut-lock in position between two nuts and
locking the same upon the bolt Fig 5 is a similar view showing the con-
stiuction of the locking washer when the object against which it bears is of wood
Fig. 6 is a plan view of the same construction of washer. Fig. 7 is a plan
view of a modified form of washer Fig 8 is an edge view of the same; and
Fig 918 a vertical sectional view, shewing a further modification.
Referring to the drawings, A indicates a bolt, and C nut engaging the same
The locking washer D 18 slit inwardly and radially, forming a plurality of lock-
ing tongues E The slits do not extend entuely to the central opening F, but
terminate short thereof, as illustrated in Fig 3.
Tongues G extend into said bolt opening F of the washer on opposite sides
of its centie, and are bent forwardly as illustrated in Fig 2 to extend into notches
formed at opposite sides of the bolt opening of the object against which the washer
beais
Should this object be a fish-plate, these notches will not have to be formed
therein, inasmuch as the bolt opening is usually oblong so that a space 18 pro-
vided at each side of the bolt. These tongues prevent the rotation of the washer,
and a very simple yet effective construction is provided After the nut has been
properly adjusted one of the locking tongues of the washer is bent to engage the
nut, so that the latter is locked from rotation. By having the tongues formed
about the entire surface of the washer by shitting the same radially, a locking
tongue is always in position to engage the nut regardless of the position assumed
by the latter when it has been properly adjusted upon the bolt.
When the locking washer is in position between two nuts, as shewn in Fig 4,
one of the tongues E may be bent in one duection to engage the nut C while
another may be bent in the opposite direction to engage the nut I. Thus the
washer can be used to lock two nuts at the same time and prevent rotation thereof
upon the bolt. In this construction the tongues G are not used, as they are not
necessary, as will be understood.
Should the object against which the washer is to bear, be of wood, as illustrated
in Fig 5, a somewhat different construction 18 provided, in this instance the
tongues of the washer are dispensed with The washer in this construction has
the oppositely extending tangs K formed on opposite sides of and adjacent to
the bolt opening, by slitting said washer and springing the shit portions out-
wardly at light angles thereto. These tangs engage the wood against which the
washer bears and are forced thereinto by the nut, so as to prevent rotation of the

page_text: washer. The locking construction of the washer by means of which the nuts
are prevented from rotating upon the bolt is the same as that fist described.
In the modification illustrated in Figs 7 and 8, each tongue E of the washer
is formed with a flute or corrugation L in its outer face, so that when the same
18 in position upon the bolt and engages the fish-plate or other object against
which it is adapted to bear, a round or pointed tool may be inserted in the coiru-
gations and the tongues readily bent to engage the nut.
In the modification illustrated in Fig. 9, the bolt is formed, on opposite sides
of its centre, with longitudinal channels or grooves B, and when the washer is
forced upon the bolt, the tongues G bend backwardly to form spring tongues
which extend into the bolt opening of the nut. These tongues prevent rotation
of the washer, and by engaging the bolt tend to prevent backward movement of
the washer thereof By having the tongues extended into the bolt opening of the
nut, they are securely held in engagement with the bolt, The washer may be
made in any preferred shape, as, for instance, square or oblong.
From the above description it will be seen that I have produced a very simple
construction of nut-lock, which takes the place of the ordinary washer, and which
18 exceedingly cheap of production and very effective in operation, as has been
demonstrated by actual tests.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim 18
In a nut-lock, the combination with a bolt and a nut, of a locking washer
having a cential opening to receive the bolt and slit radially from a point adjacent
to said opening to the outer edge thereof to form a continuous series of bendable
tongues, either one of which is adapted to be bent over the nut, said tongues
being provided with central longitudinal flutes or corrugations, formed by
indenting the same, and said washer having a pair of tongues or locking pro-
jections arranged at opposite sides of said central opening, substantially as
described.
