DIECILICATION,
An Improved Lock Box for Wheel-hubs.
I, SAMUEL STEPHEN ARNOLD, Commercial Traveller, residing at 60 Lakeview
Avenue, in the City of Toronto, County of York, Province of Ontario, 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:-
This invention relates to a device whereby the wheel-hub can be securely locked
to its respective journal-box and the wheel and its journal box will be compelled
to revolve together whilst the wheel is upon its axle, and also to so construct the
said device that when it is necessary to remove the wheel from the axle the wheel
can be removed without the necessity of removing the journal-box or bearings;
and the invention consists essentially of the device hereinafter more fully set forth
in the Specification and more particularly pointed out in the claims.
In the drawings
Figure 1 is a perspective view of a section of an axle, the journal-box and the
lock-box.
Figure 2 is a sectional view showing the same parts and the lock-box fitted into
the wheel-hub.
Figure 3 is a perspective view of the lock-box.
Figure 4 is a perspective view of the journal-box.
Like numerals of reference refer to like parts throughout the Specification and
drawings.
The lock box consists essentially of a metallic shell 1, of any suitable size and
shape and is provided with two outwardly extending flanges 2, which serve as
splines to enter the wood work surrounding the bore of the hub to lock the said
metallic shell 1 to the hub 3.
In the drawings I have shown the metallic shell 1 to be constructed particularly
for a buggy, or vehicle wheel, but the device may also be employed in any form of
wheels whatever, such as, car-wheels, turbine or water wheels, loose pulleys, or in
the hub of any other device revolving on its axis.
The metallic shell 1, as before stated, is driven into the bore of the hub and is
locked therein by the splines 2 entering the wood work surrounding the bore and
consequently the said metallic shell is compelled to revolve with the said hub.
Formed in the metallic shell are two or more longitudinal slots 4 diametrically
opposite each other and located mediately between the flanges 2. By reference to
the drawings it will be noticed that these slots 4 are formed in the central portion
of the walls of the metallic shell 1, and that between each end of the said slots
and the ends of the said metallic shell 1 is a band of metal 1.
The object of this construction is to prevent the sides of the said slots closing
upon each other whilst the metallic shell is being driven into the wood work of the
hub, the band 1" being of sufficient strength to cause the said metallic shiell to
retain its proper form, and resist all strains upon it from the hub 3.
The bore of the metallic shell I is arranged to fit snugly the journal box 5 which
uns upon the axle 6. The journal box 5 is provided with wings or ribs 7 to fit
he longitudinal slots 4. The entrance of the wings or ribs 7 into the slots 4 lock
ogether the journal box and the metallic shell and cause the simultaneous
revolution of the said metallic shell and the said journal box. The journal box 5
5 provided with a shoulder 5 on its inner end which abuts against the inner end
of the metallic shell 1. The inner end of the metallic shell 1.is provided with a
houlder or circular flange 1 which abuts against the wood work of the side of the

hub 3 and prevents the metallic shell entering too far into the bore of the said hub..
The outer end of the journal box 5 is screw threaded and fitted on the screw
threaded portion of the said journal box is a nut 8, which is screwed against the
outer end of the metallic shell 1 and prevents the metallic shell, and consequently
the hub, shifting its position on the journal box 5.
As before stated the metallic shell 1 is locked or securely fastened to the hub 3,
and it might now be stated that the journal box 5 is locked on the axle 6 by means
hereinafter set forth.
When it is necessary to remove the wheel from the journal-box the dust nut 9
and the nut 8 are removed and the metallic shell 1 with the hub and wheel are
slid along the journal box until the said metallic shell shall have cleared the end
of the journal box and axle. To provide a means for oiling the axle in event.
of rust or dampness I have forined through the journal box 5 to the axle 6 a
passage 10 by means of which oil is fed to the axle.
The inner end of the journal-box 5 is enlarged to form a cup-shaped recess 11
which has a hardened bearing surface 12. On the bearing surface 12 is adapted
to run the hardened steel balls 13. Formed on the axle 6 contiguous to the
recess 11 is a cup 14 which encloses the end of the journal-box 5 and closes the
end of the recess 11. On the axle 6 and within the cap 14 is an enlargement 15
which is hardened to provide a surface for the balls 13 to run on, the balls 13
running on the two surfaces 12 and 15.
The outer end of the journal-box 5 is provided with a cup-shaped recess 16 the
surface of which is hardened, and fitted to the outer end of the axle 6 is a nut 17
to close the end of the recess 16. The nut 17 is provided with a hardened
surface 17". The balls 13 within the recess 16 travel on the hardened surface of
the recess and on the hardened surface 17" of the nut 17. The bore of the journal
box 5 is sufficiently large to prevent the metal which surrounds the said bore coming
in contact at any time with the axle 6. The bearing surfaces of the said journal-
box at all times turn on the balls 13 within the recesses respectively 11 and 16,
consequently the journal-box touches the axle at no point whatever, thus preventing
the occurrence of any friction at any point except on the balls 13, which being of
hardened metal reduces the friction to a minimum amount.
The nut 17 closing the end of the journal-box 5 is slightly less in diameter than
the diameter of the hole or opening through the nut 8 to permit of the said nut being
removed from or replaced on the screw threaded end of the journal-box 5 without
the necessity of interfering with the said uut 17, and on the outer side of the nut 17
is a washer 18 equal in diameter to the nut 17 to allow the nut 8 to pass thereover.
Enclosing the washer 18 and nut 17 and end of the journal-box 5 is a dust nut 9
which it is always necesssary to remove before the nut 8 can be unscrewed and
the hub and wheel removed.
The metallic shell is channelled or grooved from one end. to each of the longitu
dinal slots 4 in order that each wing or rib on the outer side of the journal box 5
may enter its respective groove or channel and pass easily to the said longitudinal
slots 4.
The essential feature of the invention consists in the means for removably locking
the hub to the journal-box and this means can be as readily employed on the axle
and journal-box of any form whatever and provided with any style of bearing
surfaces.
In fitting this invention to a metal wheel the metal shell can be cast integral
with the hub or the bore of the hub can be provided with grooves or channels to
receive the splines.
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
claim is
