Complete Specification Accepted, 17th Aug., 1888
I, ROBERT WALTER GARDNER, of 2 Earlham Road, Bowes Park, Tottenham,
Middlesex, Mechanical Engineer, do hereby declare the nature of this invention to be
as follows:-
:―
This invention relates to means for locking collets and nuts on axles, the essential
feature being, making holes at an angle in V or A order in the collet preferably from
the face and over the flat portion which fits on the flat of the axle arm, a hole or holes
being also made in the flange of the nut but coinciding with those in the collet for
the reception of the legs of a split cottar, which legs or ends open or close if pre-
viously open while being inserted into the angled holes in the collet the bow of the
split cottar resting upon the flat or square of the nut.
The two holes, if two holes be made in the collet may be close together from the
starting point or face and incline away from each other or be at a distance apart and
ncline towards each other, in which case a modified shape of split cottar, or it may be
a pronged or two legged plate, or a staple can be employed, the flat or connection
piece resting upon the flat or square of the nut, or it may be so arranged that the
holes instead of being in the flange of the nut, they may be in the body of the nut or
in a recess in the flat or square.
The two angled holes in the collet may be parallel or close together or they may be
at a small distance from each other and instead of the flange of the nut being formed
with holes, notches may be made and so shaped that the shoulders of the split cottar,
or of the pronged or double legged plate or staple is firmly lodged therein.

Means for Locking Collets and Nuts on Axles of Road Vehicles.
I, ROBERT WALTER GARDNER, of 2 Earlham Road, Bowes Park, Tottenham,
Middlesex, Mechanical Engineer, 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 :-
:-
This invention relates to means for locking collets and nuts on axles, the essential
feature being, making a hole or holes at an angle in single order, thus 1, in double or
parallel order, thus 11, in V or A order in the collet from the face and preferably over
the flat, portion which fits on the flat of the axle arm, a hole or holes being also made
in the flange of the nut but coinciding with that or those in the collet for the recep-
tion of the leg or legs of a cottar pin which legs or ends open, or close if previously 1
open, while being inserted into the angled holes in the collet, the bow of the cottar
resting upon the flat or square of the nut.
The two holes, if two holes be made, in the collet, may be close together from the
starting point or face and incline away from each other or be at a distance apart and
incline towards each other, in which case a modified shape of cottar pin, such as a
pronged or two legged plate, or a "staple" can be employed, the flat or connection
piece resting upon the flat or square of the nut, or it may be so arranged that the
holes instead of being in the flange of the nut they may be in the body of the nut
or in a recess in the flat or square.
The two angled holes in the collet may be parallel and close together or they may 2
be at a small distance from each other and instead of the flange of the nut being
formed with holes, notches may be made and be so shaped that the shoulder of the
cottar pin or of the pronged or double legged plate, or staple, is firmly lodged in
place.
The annexed drawings show some examples of how my invention may be carried 2
into practice.

for nuts and collets of axles as described.
3. The angle hole or holes in collet B and the cottar pin, staple, or legged plate D
when used in the manner shown on the annexed drawings and as a means for locking
axle nuts of Road Vehicles as set forth.
