PROVISIONAL SPECIFICATION.
Improvements in Nut-locks.
I, MAX ALBERS, of Gevelsberg, in the Kingdom of Prussia and Empire of
Germany, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved nut-lock of that kind, in which the nut is
prevented from turning on its bolt by means of a wedge or pin arranged to bear
against one side of the nut. The method, in general, of locking a nut by means of
a wedge or pin, without cutting the bolt, is known. The special and improved
device of my invention consists in providing a washer sufficiently enlarged on one
side of the nut to press or stamp into it a bridge or guide-way for receiving the
locking wedge, said bridge or guide-way being provided in a direction which allows
the locking-wedge to be easily introduced and adjusted parallel to one side of the
nut, after which the nut is slightly screwed further down, so as to bear with one
edge against the wedge, whereby the latter is jammed within its guide-way and
prevented from moving either backward or forward. The wedge, accordingly,
prevents the nut from turning in either direction and the nut holds the wedge in its
jammed position.
The wedge may be provided with a notch, into which the adjacent edge of the
nut is forced in the locking position, the said notch gives an additional security
against any accidental unlocking of the nut.

COMPLETE SPECIFICATION.
Improvements in Nut-locks.
1, MAX ALBERS of Gevelsberg, in the Kingdom of Prussia, and Empire of
Germany, Manufacturer, do hereby declare the nature of this invention and in
what manner. the same is to be performed, to be particularly described and
ascertained in and.by the following statement:-
My invention relates to an improved nut-lock of that kind in which the nut is
prevented from turning on its bolt when lodged in its final position by means of a
wedge or pin arranged to bear against one side of the nut.
The method, in general, of locking a nut by means of a wedge or pin without
cutting or slotting the bolt is known. My special and improved device is herein-
after described with reference to the accompanying drawings, in which,
Figure 1 is a front elevation of a portion of a rail and fish-plate secured to each
other by a screw bolt D and nut C, the nut being not yet fully locked by the
improved device of my invention.
Figure 2 illustrates the same parts showing the nut in its fully locked position.
Figure 3 is a cross section through the rail and fish-plate showing the improved
nut-lock in side elevation, and
Figure 4 is a front elevation of the same parts illustrating a modification in the
shape of the locking wedge B.
My improved nut-lock consists of a washer A. extending a convenient distance on
one side of the nut C, and I press or stamp into said side portion of the washer A
a bridge A serving as a guide way for the locking wedge B, said bridge or guide
way A leaving a recess a open within the washer A. and being made in an oblique
[Price Q77

page_text: position, thus allowing the wedge B being easily introduced and adjusted parallel
to the adjacent side of the nut C, after which the nut C is screwed fully down, so
as to bear with one edge against the wedge B, whereby the latter will be jammed
within its guide way A' and prevented from moving in either direction. The lower
end of said wedge B may be preferably formed with a notch or recess as in
Figures 1 and 2, or with a notch or recess b' as in Figure 4, into which recess or
notch the edge of the mit C is forced, the said recess or notch offering an additional
security against any automatic unscrewing of the nut.
This nut-lock, being simple in construction and cheap, affords every security
against the loosening of the nut on its bolt, and it can be manipulated with the
greatest facility.
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. A nut-lock consisting of a washer having pressed or formed into it a bridge
and recess, serving as a guide-way for a wedge to be inserted in a position parallel
to the adjacent side of the nut, substantially as set forth.
2. In a nut-lock, the combination with a washer having formed into it a bridge
and recess, of a wedge to be inserted into said bridge and locking the nut by being
adjusted parallel to one of its sides, substantially as set forth.
3. In a nut-lock, the combination, with a washer A having a bridge A' and
recess a formed into it in an oblique position, of a wedge B, having a notch 6, or
notch to receive the adjacent edge of the nut, substantially as described.
