Improvements in Locking Nuts.
I, JEAN LEON HERITIER, Professor of Chemistry, Tervoc, Co. Limerick, do
hereby declare the nature of this invention to be as follows:
I make my washer of any metal. I propose that the portion of the washer
covered by the nut may be made in the ordinary manner or it may be provided
with one or more pins on the under surface or grooved or corrugated to prevent
sliding. I allow one side to project beyond the nut and on this projection I turn
a lip which will receive and hold a key, a rod or pin being jammed between it
and the side of the nut, thereby holding or locking the nut in position. I some-
times make the projection without the turned up lip, and when I adopt this
manner I score lines or grooves parallel with the side of the nut on the projection
and on it I fit a small bit of metal close to the nut and equally scored. I fasten
both by a screw, and thereby also lock the nut.

I, JEAN LEON L'HÉRITIER, Professor of Chemistry, Tervoe, Co. Limerick, 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:
I make my washer of any metal. I propose that the portion of the washer covered
by the nut may be made in the ordinary manner or it may be provided with one
or more pins on the under surface or grooved or corrugated to prevent sliding. I
allow one side to project beyond the nut and on this projection I turn a lip which
will receive and hold a key, a rod or pin being jammed between it and the side
of the nut, thereby holding or locking the nut in position. I sometimes make
the projection without the turned up lip, and when I adopt this manner I score
lines or grooves parallel with the side of the nut on the projection and on it I fit a
small bit of metal close to the nut and equally scored.
I fasten both by a screw,
and thereby also lock the nut.
For purposes of illustration I will now refer to the annexed drawings, in
which:-

page_text: Figure 1. is a plain view of my invention.
Figure 2. sectional side elevation.
Figure 3. view of locking piece removed.
a is a locking piece having the bent or turned up end 6 and the aperture c which
is placed over a bolt or stud. The nut d is then screwed down until the projec-
tions e engage upon the material upon which the locking piece rests, thus pre-
venting same from turning. The key or bar f is then inserted between one of
the flat surfaces upon the nut and the turned up end b and thus prevents the nut d
from rotating. By this arrangement it will be seen that when the key or bar
is inserted between the nut and turned up end 6 of the locking piece the nut is
prevented from turning, and when being used the nut is turned so that a flat
surface upon same is brought into position so as to allow of the passage of the key
or bar between this flat surface and the bent or turned up end b, and then by
slightly turning the nut the key or bar f will be held in position between the nut
and the bent or turned up end b, the position of the locking piece being arranged
so that the flat surface of the nut will be available in the required position.
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 is:.
-
1. The combined construction and arrangement of the various parts substan-
tially as described and illustrated herein.
2. In means for locking nuts: a locking piece, provided with projections or
pins for engagement in or upon a surface, having a bent or turned up end; said
locking piece having an aperture through which the bolt passes so that when a
nut is screwed upon said bolt the locking piece is secured in position, and a key
or bar may then be inserted between the nut and the bent or turned up end for the
purpose of preventing the nut from becoming loose or turning upon the bolt or
stud.
