Improvements in Combined Axle-nut Wrench and Wheel Lifter for
the Lubrication of Axles.
We JAMES ROBERTSON, Carpenter, ANSLOW BARRINGTON RUDD and HENRY
HORATIO NEILSON, Jewellers, all of the Town of Perth, in the Province of
Ontario, in the Dominion of Canada, 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 has for its object to remove an axle-nut from an axle and replace
the same after lubrication of the axle without detaching the nut from the wrench,.
and to lift the axle to apply the lubricant, so that when the wheel is off the ground,
the wheel may be slipped off the axle onto an arm of the lifter in alignment with.
the axle, the axle then lubricated, the wheel replaced and the nut restored, in a
cleanly manner.
My invention consists of a combined axle-nut remover and axle lifter, and
said lifter comprises a curved bar to span a hub, said bar provided with a handle
extending outwardly from one end of the bar and in alignment with the opposite
end, and an inwardly projecting arm in alignment with the handle, said arm suitably
shaped at the extremity to engage the underside of the end of the axle when the
opposite end of said bar rests on top of the axle at a distance from the hub of the
wheel, so that by lifting the handle, the axle will be raised, whereby the wheel will
be off the ground and can be slipped from the axle onto the arm of the lifter for
lubrication of the axle and replacement of the wheel, the nut having been
previously removed. Also, in combining with said lifter a nut-wrench or axle-nut
remover, consisting of spring bifurcated jaws terminating in a shank provided with.
a screw thread at the converging end and inserted in a tubular head journaled in a
bearing or round hole near the intersection of the bar, handle and arm, said shank
provided with a thumb-nut to draw the jaws into the tubular head and thereby
cause them to seize the nut, and said head is provided with a crank handle to
rotate the head, jaws and nut collectively, in removing and replacing the axle-nut,.
and the jaws hold the nut when off the axle until replaced and the thumb-nut
unscrewed.
The lifter spans the hub of the wheel and one end is inserted between the spokes
to bear on the axle while the other end of the axle bears on the arm of the lifter,.
so that by lifting the instrument by the handle, the axle will be raised and the
wheel removed from the ground.
A, is an arch-shaped frame or curved bar, adapted to span the hub of a wheel.
One end of said frame terminates in an outwardly extending handle B, in alignment
with the opposite end of the frame A, and inwardly from the intersection of the
frame and handle projects an arm C, in alignment with the handle and said arm at
the extremity is suitably notched or provided with a ferrule C₁, grooved to receive
the end of the axle from which the nut has been taken. One end of the curved bar
or frame A, is inserted between the spokes of the wheel and rests on the top of the
axle when the arm C, engages the underside of the extremity of the axle, so that
by raising the lifter by the handle, the axle will be raised, whereby the wheel can
be slipped off the axle onto the arm C, to admit of the lubrication of the axle.
The ferrule C', admits of the replacement of a new one when worn by use.
The nut remover is combined with the lifter near the junction of the handle and
arm C, the intersection being enlarged so as to produce a tapering hole or tubular
bearing 2, in which is inserted a tubular head 3, provided with a flaring mouth,
and having at the opposite end a rectangular termination 4, on which to slip the
eye of a crank handle 5, to rotate the head in its bearing when unscrewing the nut
Die Q1

page_text: by turning the handle. 6, 6, are bifurcated spring jaws terminating in a shank, aud
said shank is inserted through the tubular head 3, and provided with a thumb nut 8,
so that by screwing the nut the jaws will be drawn into the head and cause them to
close against the nut and hold it fast until released by unscrewing the nut after the
nut has been replaced on the end of the axle after lubrication of the axle, and
replacement of the wheel thereon. 9, 9, are beveled jaws projecting from the
head 3, to centre the nut in the jaws 6.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
I claim is,
1. An axle-lifter, consisting of a curved bar or frame A. one end terminating
outwardly in a handle B, and having an arm C, extending inwardly, as set forth.
2. A combined axle-lifter and nut remover, composed of the curved bar or
frame A, adapted to span a wheel-hub, one end terminating in an outwardly
extending handle B, and having an arm C, extending inwardly towards the opposite
end of the bar, and an axle-nut remover or wrench journaled in a hole near the
intersection of said handle and arm, and consisting of the bifurcated spring jaws 6,
inserted in a rotary head 3, and provided with a thumb-nut 8, said tubular head
provided with a crank handle 5, substantially as set forth for the purpose described.
Dated this 20th day of April 1893.
