BERNARD JOSEPH Maloney, 1, Greyfriars Place, Edinburgh, Watchmaker, do
hereby declare the nature of this invention to be as follows:-
Ends of bolts or axles on which nuts are fitted are part formed a D square or
such like shape and part screwed. Nut A of the required diameter and length is
fitted to this D or square of bolt or axle and is hollowed out on one end and has
ratchet or other shaped teeth cut on same end and also an inner shoulder or
collar. Nut B fitted to screw of bolt or axle is turned at one end to fit into
hollow in nut A (so that when screwed in position on bolt or axle it bears on
the shoulder or collar of nut A & thus binds it,) and has a shoulder or collar at
the other end. The outside of nut B in front of collar is shaped in a D or other
such like form. Nut C is similar to nut A and is fitted easily on the D or square
of nut B. When nuts A & B are fixed in the required position nut C is pushed
towards nut A & the teeth are lock together. This binds or locks the three nuts
together on the axle. Nut C may be kept in position by a spiral spring of the
required strength placed at the back of the nut C and bearing against the collar
of nut B and thus keeping the teeth of nuts A & C locked together or by a
pinch screw passed through side of nut C and binding it on nut B. When a
wheel is locked or keyed on axle F, these nuts may be used to form a running
surface by covering them with a metal tube D having a cover at one end fitted to
the D or square of bolt or axle F and also a cover E screwed to bolt or axle F.
Fig. 1 shews nuts A B & C, locked on axle F.
Fig. 2 shews nuts A, B, & C with tube and cover D & E in position on axle F.
In lock nuts for plummer blocks and the like when the bolts are not D or square
at the shoulder or collar nut A, may have slots, holes, or studs put in it and corre-
sponding slots holes or studs in the wheel or metal to be locked, the object being
to prevent nut A, from turning round after it is placed in position for locking.

Improvements in Locking Bolts and Nuts and the like.
BERNARD JOSEPH MALONEY, 1, Greyfriars Place, Edinburgh, Watchmaker, 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 follow-
ing statement, reference being made to the drawings filed with my Provisional
Specification, and to the drawing filed herewith.
Ends of bolts or axles on which nuts are fitted are part formed a D, square or
such like shape and part screwed. Nut A of the required diameter and length is

ratchet or other shaped teeth cut on same end and also an inner shoulder or
collar. Nut B fitted to screw of bolt or axle is turned at one end to fit into
hollow in nut A (so that when screwed in position on bolt or axle it bears on
the shoulder or collar of nut A and thus binds it) and has a shoulder or collar
at the other end. The outside of nut B in front of collar is shaped in a D or
other such like form. Nut C is similar to nut A and is fitted easily on the D
or square of nut B. When nuts A and B are fixed in the required position nut C
is pushed towards nut A and the teeth are locked together. This binds or locks
the three nuts together on the axle. Nut C may be kept in position by a spiral
spring of the required strength placed at the back of nut C, and bearing against
the collar of nut B and thus keeping the teeth of nuts A and C locked together
or by a pinch screw passed through side of nut C and binding it on nut B.
When a wheel is locked or keyed on axle F, these nuts may be used to form a
running surface or journal by covering them with a metal tube D, Figs. 2 and 3,
having a cover at one end fitted to the D or square of bolt or axle F and also
a cover E screwed to bolt or axle F. Fig. 1 shews nuts A, B, & C locked on
axle F.
Fig. 2 shews nuts A, B, and C with tube & cover D, & E in position on axle F.
In locknuts for plummer blocks and the like when the bolts are not D or square
at the shoulder or collar, nut A may have slots holes or studs put in it and corre-
sponding slots holes or studs in the wheel or metal to be locked the object being
to prevent nut A from turning round after it is placed in position for locking.
When it is desired to lock a wheel on its axle, as in the case of railway plant
and the like," a metal tube D Fig. 3, of the required length and diameter has a
feather G, fitted on end of tube towards hub of wheel, this feather fits in a corre-
sponding slot in hub of wheel and when bound into position by nuts A, B, C the
wheel, tube, and nuts are firmly locked on the axle."
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:
First, The arrangement of toothed nuts on bolts or axle and on nut B sub-
stantially as herein shewn and described.
Second, The arrangement of nuts when locking on metal tube D, substantially
as herein shewn and described.
Third, The arrangement of feather, studs or slots in tube D and corresponding
feathers, slots, or studs in wheel when desirable, substantially as herein shewn
and described.
