D is a linch pin.
The position of the holes in the washer A (to fit over the linch pin D) is
advantageously determined and arranged as follows:-
These holes in the washer A (as shown by way of example in Fig. 3) are
exactly concentric and such holes down one side of the washer for instance to
the left of the said tooth on said washer occupy exactly the position of the solid
parts between the holes on the other side of said tooth and vice-versa so that
when the washer is placed on the bolt C in case one of the holes therein does not
correspond with the position of the linch pin D by withdrawing the washer from
the bolt and reversing the washer and replacing same on the bolt C then a hole
will be found to correspond to the position of the linch pin D so as to fit over
same.
I find it advantageous not to place any such hole or holes just over the afore-
said tooth in the washer A (see Fig. 3) so that the latter may not be thereby
weakened in any way.
In case of this solid part of the washer just over said tooth coming over the
linch pin D then by withdrawing the washer from the bolt and placing the tooth
thereof in the other longitudinal groove in the bolt C thereby one of the concentric

page_text: holes in said washer will now be found to exactly coincide with the position of the
linch pin as above described.
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 locking washer with a row of holes at irregular distance from the tooth
on the inner circle of the washer substantially in the manner and for the purposes
hereinbefore described.
2. The combination with a bolt and nut thereon of a non-rotatable washer
having a tooth or projection on the inner edge thereof adapted to fit in a longi-
tudinal groove in said bolt and means to rigidly attach said washer to the outside
face of said nut.
3. The combination with a longitudinally grooved bolt and a nut screwed
thereon of a washer having a tooth on the inner edge thereof adapted to fit in
said longitudinal groove and thereby prevent rotation of said washer a series of
concentric holes in said washer and a linch pin carried with the point outwards in
said out and adapted to pass through one of said holes in said washer and be there
rivetted or fixed so as to thus rigidly attach the nut to said washer substantially in
the manner and for the purposes hereinbefore described.
4. A longitudinally grooved bolt such as C a nut such as B screwed thereon
and a washer such as A having a tooth on the inner edge thereof adapted to fit
in a groove in C and a series of concentric holes in said washer in combination
and acting in conjunction with a linch pin such as D arranged mounted and
carried in the said nut B and adapted to pass through one of the said holes in A
and be there rivetted or otherwise suitably fixed substantially in the manner and
for the purposes herein before described and illustrated in the drawings hereunto
annexed.
