PROVISIONAL SPECIFICATION.
An Improved Method for Locking Nuts to Bolts or Screws.
AARON MOSLEY 230 Arkwright Street Nottingham Mechanic do hereby
declare the nature of this invention to be as follows:-
I use two nuts so constructed that when adjusted form to all appearance
one nut.
One of these nuts has on one of its sides a circular recess cut in a suitable depth.
This recess is slightly larger in dia. at the bottom than at the entrance. The other nut
has on one of its sides a circular projection made to fit exactly the entrance to the
circular recess of the recessed nut. The hole in the nut that has the circular projection
is considerably smaller in the projecting portion than in the other part of the nut.
The two nuts are then put together and force is used the projecting portion is
forced into the recess in the recessed nut and to all appearances form one out.
I then insert a circular wedge and again use force which causes the projecting
portion on the nut to expand and fill up the space at the bottom of the recess of the
recessed nut thereby completely locking both nuts together, yet at the same time
allowing each nut to move in a circular direction. The uuts then receive the screw
thread and are then complete. Having the power to move either of the two nuts
either way in a circular direction I can at pleasure make both the nuts fast to the
screw or bolt or make them loose. This operation can be repeated continuously
without damage to either the screw or bolt or to the two lock nuts.

AARON MOSLEY 230 Arkwright Street Nottingham Mechanic 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 will be better understood by the following explanation. I use two
nuts so constructed that when adjusted form to all appearance one nut. One
of these nuts has on one of its sides a circular recess cut in a suitable
distance this recess is slightly larger in diameter at the bottom of the recess than
at the entrance. The other nut has on one of its sides a circular projection made
same depth as the recess in the recessed nut and the same in diameter as the
entrance to the recess of the recessed nut. The hole in the nut that has the circular
projection is considerably smaller in the projecting part than in the other part of the
nut. The two nuts are then put together the projecting portion of one nut fitting
into the recessed part of the other nut 1 then insert a circular wedge or punch into
the hole of the nut that has the circular projection. I then use force to the wedge
which causes the wedge to open out the projecting part of the nut and fill up the
space at the bottom of the recess in the recessed nut thereby completely locking

page_text: the two nuts together forming to all appearance one nut. The nut or nuts then
receive the screw thread and the nut is then complete.
Having the power to move either nut either way in a circular direction by the
circular locking of the two nuts I can as required make both nuts fast to a screw or
bolt or make them loose. This operation of locking the nuts to the screw or bolt
can be repeated any number of times without damaging either the screw thread in
the nuts or the screw thread on the screw or bolt.
My invention is illustrated in the drawing annexed.
Figure 1 is a section of the two parts from which the combined nut and lock nut
are to be formed.
Figure 2 is a plan of the same.
Figure 3 is a section of the same parts when the swivel joint which is to connect
them together bas been completed.
Figure 4 is a section of the same parts when a screw thread has been cut
in them.
Figure 5 is a side elevation of the combined nut and lock nut.
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 :-
T'he method herein described for locking the two nuts together forming to all
appearance one nut with a continuous screw thread at same time having the power
to move either nut either way in a circular direction.
