Engineer do hereby declare the nature of this invention to be as follows:-
:-
This Invention relates to the production of a simple effective and reliable lock-
nut for general use in or connected with machinery.
My improved lock-nut is made of any suitable metal, and is in two parts,-an
outer and an inner one;-the inside of the outer part is tapered from its top (or
larger) opening down to its bottom (or smaller) opening; near the bottom opening
it is screw-threaded inside for the screw-threaded portion of the inner part of the
nut to screw into.
The inner separate portion of the nut is a out or slit tube or barrel, and is
screw-threaded on its exterior. to correspond with and screw within the inside of
the outer part of the nut. The inside of this cut or slit tube or barrel is plain
screw-threaded, or when required it can also be fluted or grooved so as to cause it
to keep more grip or hold on what it is put on.
Lock-nuts constructed according to this invention will be manufactured of all
sizes and strengths, the longer sizes where required will be screw-threaded in the
middle and be tapered from each opening to the screw-threaded portion; and in
some cases the inside of the cut or slit tube or barrel will also be made with a slot
or groove in it for the reception of a key to keep the parts in position while being
screwed up.

I WILLIAM WARD of 23 Ebenezer Street Sheffield in the County of York
Engineer do hereby declare the nature of the said invention for "AN IMPROVED
LOCK-NUT APPLICABLE FOR MACHINERY IN GENERAL and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement in writing and on reference to the accompanying sheet of
drawings, that is to say :-
This Invention relates to the production of a simple effective and reliable lock-.
nut for general use in or connected with machinery; and in order that the
practical carrying out of my said invention may be fully understood I have
shown on the accompanying sheet of explanatory drawings, some forms (as
examples) of my improved lock-nut.
This lock-nut is made of any suitable strong metal, it is constructed in two
parts or pieces, an outer and an inner one; and lock-nuts made according to this
invention can be manufactured of all sizes and strengths as required.
Figure 1, on the accompanying sheet of drawings is a part sectional elevation of
my lock-nut as applied to a bolt.
Figure 2, is a plan of the lock-nut without the bolt.
Figure 3, is an elevation of the slit tube or barrel, being the inner part of the
lock-nut.
Figure 4, is a cross section; and Figure 5, is a longitudinal section of my lock-
nut as applied for coupling shafts bolts bars or rods.
The same reference letters indicate the same or like parts in all the Figures.
a, is the outer and b, the inner part of the lock-nut. The inside of the outer
part is tapered from its top or larger opening, or from one of its openings, to its
bottom or smaller opening, or to its other opening,-according to the position in
which the lock-nut is required to be affixed; the drawing showing it as tapering
from its top smaller opening to its bottom larger opening. Near to one of the
openings it is internally screwthreaded as at o, for the screwthreaded portion of
the inner part b, of the nut to be screwed into.
The inner or separate portion 6, of the nut is made as a cut or slit tube or
barrel, which is correspondingly tapered externally and is screwthreaded on its
exterior at d, to correspond with and screw within the inside of the outer part of
the nut. e, shows the cut or slit in the tube or barrel-f, represents the flats on
the outer. portion of the nut to which the spanner or other tool is applied in
fastening up the lock-nut, which flats can be made of any necessary size or shape.
The inside of the cut or slit tube or barrel b, is plain screwthreaded, as at h, or
when required it is also fluted or grooved, as shown at i, so as to cause it to have
and retain more grip or hold on what it is put or affixed to.
Where longer sizes of the lock-nut are required, such as, when they are to be
used for coupling shafts, or long or short bolts bars or rods, together, they will
be screwthreaded in the middle, as shown at c, d, Figure 5, and tapered towards
the screwthreaded part from each opening; and when used for coupling shafts
together, or for connecting long or short bolts bars or rods, the inside of the cut

page_text: or alit tube or barrel b, will also be made with a slot or groove in it, as at k, to
receive a key l, a key way m, for which is formed in the shaft or bolt g, (See
Figures 4 and 5,) the key being inserted to keep the parts of the shaft bolt or rod
in position while the lock-nut is being screwed up. The key and keyway can be
either straight as shown, or it can be tapered a little each way towards the middle.
In this form of the lock-nut the slit tube or barrel b, is made plain internally.
ff, are the flate made on the outside of the outer part of this form of lock-nut for.
the spanner to hold on when screwing up.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed or put in practice
I declare that what I claim is:-
The new and peculiar general construction as a whole of a lock-nut made
separately of an outer and an inner part, substantially as herein set forth and as
illustrated on the accompanying sheet of drawings, and the application and use of
such lock-nut for machinery in general.
