Improvements in or connected with Spindle and Hub Protectors.
I, WILLIAM HARROLD HOLDEN, of Idaho Falls, in the County of Bingham and
State of Idaho, United States of America, Lawyer, 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: -
The invention relates to improvements in spindle and hub protectors.
The object of the present invention is to improve the construction of devices
for protecting hubs and spindles and to provide a simple, inexpensive and
efficient one, adapted to be readily applied to the wheels and axles of carriages,
wagons and other vehicles, and capable of effectually excluding dust, sand.
mud and the like from the bearing, and of shedding the same from the hub. A
further object of the invention is to provide a device of this character which,
in case it should be submerged by reason of a vehicle crossing a stream, will
cause any water collecting in it to drain thoroughly from it so that there will
be no liability of the parts accumulating water and rusting out.
The invention consists in the construction and novel combination and arrange-
ment of parts, as hereinafter fully described, illustrated in the accompanying
drawings and pointed out in the claims hereto appended.
In the drawings; -
Figure 1 is a perpective view of a device constructed in accordance with this
invention and shown applied to a hub and an axle.
Figure 2 is a longitudinal sectional view of the same.
Figure 3 is a transverse sectional view on line 3-3 of Figure 2.
Figure 4 is a detail perspective view of the shield showing the inner or rear
portion thereof.
Figure 5 is a similar view of the annular band, showing the same applied
to the hub.
Like numerals of reference designate corresponding parts in all the figures
of the drawings.
1 designates a shield constructed of thin metal or other suitable material,
designed to be mounted on an axle 2, adjacent to the inner end of the hub 3,
and extending over the same, as clearly illustrated in Figure 2 of the accom-
panying drawing. to exclude dust, sand, mud and other accumulation from the
bearing of the wheel and prevent the same from reaching the spindle of the
axle. The shield 1, which is substantially bell-shaped, has a flared outer por-
tion and it is provided with a rounded inner or back portion 5, having an aper-
ture 6, conforming to the configuration of the body portion of the axle. This
aperture, which is rounded at the top and straight at the bottom, is enlarged at
the sides at 7, to enable it to receive the spindle, so that the shield may be intro-
duced on the end of the axle.
The flared portion 4 at the outer end of the shield has only a slight flare, as
shown, and the shield is provided at its inner end with upper and lower arms 8
and 9, extending along the top and bottom of the axle and conforming to the
configuration of the same.

page_text: The upper arm 8 is curved in cross section, and the lower arm, which is
straight to fit the bottom of the axle, is provided at opposite sides thereof with
longitudinal flanges 10, which embrace the sides of the axle. The shield is
attached to the axle by means of an axle clip 12, which is provided at opposite
sides with enlargements .or ears 13, adapted to cover the side extensions
the aperture 6 of the shield, to exclude dust, sand, mud and other accumulation
therefrom. The axle clip, which is of the ordinary construction, has its ends
threaded and connected by a plate which is engaged by nuts 15.
of
In order to close practically the outer end of the bell-shaped sleeve, the hub
is provided at its inner end with a band or collar 16, substantially triangular in
cross section and presenting a sloping outer side 17, adapted to shed any dirt,
sand, mud or other accumulation falling from the wheel upon the device. The
sloping side also sheds water and prevents rain falling upon the device from
entering the bearing. The band or collar is slightly smaller than the flared
portion of the shield so that it will rotate freely therein, and it may be con-
structed integral with the inner end band of a hub, or be secured over the
ordinary end band, in any suitable manner. The former construction is pre-
ferable when the device is applied to a wheel during the manufacture thereof,
and the latter construction is adapted to be applied to wheels in use.
The invention has the following advantages:
The device, which is simple and inexpensive in construction, is adapted to
be readily applied to an axle and a hub, and it is capable of use on all kinds of
wheeled vehicles, either heavy or light. The rounded inner portion of the
shield is adapted to shed sand, mud, dirt and water, and the sloping or inclined
outer portion of the collar or band extends beyond the flared portion of the
shield and is arranged to shed accumulation and prevent sand, mud and the like
from entering the device and reaching the bearing of the wheel. Should the
device be submerged by reason of a vehicle being driven through a stream,
the water will thoroughly drain from the same, so that there is no liability of
the device accumulating moisture and rusting out.
Changes in the form, proportion and minor details of construction may be
resorted to without departing from the spirit or sacrificing any of the advantages
of this invention.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A device of the class described comprising a substantially bell-shaped
shield, designed to be mounted on an axle and adapted to extend over the inner
portion of the hub, and a collar or band designed to be mounted on the said hub
and arranged within the outer end of the shield and substantially closing the
same, said collar or band being provided with an inclined or tapering portion
extending beyond the outer end of the shield and adapted to shed water, sand,
mud and other accumulation and exclude the same from the interior of the
device, substantially as described.
2. A device of the class described comprising an annular shield designed to
be mounted on an axle and adapted to extend over the inner portion of the hub,
and a collar or band designed to be mounted on the hub and arranged within
and substantially closing the outer end of the shield and having an inclined or
tapering portion lying beyond the same, substantially as and for the purpose
described.
3. A device of the class described comprising a substantially bell-shaped
shield having a slightly flared outer portion and designed to be secured to an
axle, and a collar or band designed to be mounted on a hub, arranged within
the flared portion of the shield and substantially closing the same, said collar
or band being substantially triangular in cross section and having its outer
inclined portion located beyond the shield, substantially as described.

page_text: 4. A device of the class described comprising a shield of annular form pro-
vided at its inner end with an aperture conforming to the configuration of an
axle, and having enlarged side portions, whereby it is adapted to permit the
shield to be passed over the spindle of the axle, arms extending from the top and
bottom of the aperture of the shield and conforming to the configuration of the
axle, an axle clip for securing the arms to the axle, said axle clip being provided
at opposite sides with enlargements or ears arranged to cover the enlarged side
portions of the aperture, and a collar or band designed to be mounted on a
hub and arranged within the shield, substantially as described.
