17 Claims. ‘ (Cl. 295-41)
This invention relates to improvements in
washer from turning relative to the axle, and
‘wheel and axle assemblies and more particularly _ the other ?nger being engaged in one of a series
. of notches in the periphery of the nut 20. It will
concerns a simply and cheaply constructed ar
rangement which is particularly adapted for em
5 ployment with anti-friction bearings.
One of the features of the present invention is
the provision of a drawn metal cap member co
operative'with wheel and axle structures for re
taining them in assembled condition.
10
Another feature of the present invention is the
provision of such a device in combination with
packing and spacing means for establishing an
‘assembly which is tight both in the mechanical
sense and against the escape of lubricant.
Further features of the invention relate to the
15
manner of making and assembling the steel cap,
to the general combination of the assembly of
parts, and to the various details as will appear
more fully in the course of the following speci?ca
tion and claims.
be noted that when the nut 20 is tightened, the
bearings and spacers are clamped tightly to- 5
gether and upon the axle.
The wheel is shown as being of ?anged type and
comprising a tread portion 25 having spokes 26
connecting it integrally with a hollow hub which
includes the closed outer end 21, a central por- 10
tion 28, and an inwardly projecting portion 29
extending beyond the inner surfaces of the spokes
and in the present illustration likewise extending
inwardly beyond the plane which is tangent to the
inward surfaces of the wheel ?anges. The hol- 15
low hub has a cylindrical internal surface 30 ad
jacent its inner end, for receiving the outer or
hub race 3| of the ‘first said anti-friction bearing;
adjacent this surface 30 is an abutment 32-for
‘ limiting the relative movement of the hub with 20
'
The present assembly is of the same general respect to the race 3|, and being here illustrated
nature as that set out and claimed in the 00-» as a. simple peripheral rib of internal diameter

No. 652,737, ?led January 20, 1933.
a‘
An illustrative form of practicing the inven
" tion is set out on the accompanying drawing, in
which:
~
Fig. 1 is a diametrical sectional view showing
a wheel and axle assembly including the present
3,) invention.
'
.
Fig. 2 is a view showing the blank from which
the pressure cap is made.
Figs. 3 and 4 are respectively end and side
views of the cap after being formed.
In the drawing, the axle' ID has a cylindrical
u.)
surface ll spaced from its end, a second and
smaller cylindrical surface l2, 2. third and yet
smaller cylindrical surface l3, and a threaded
portion 14 at the end. The inner or axle race
40 I5 of an anti-friction bearing having illustratively
n...
the balls I6, is seated on the cylindrical portion
i2 and bears against the shoulder between the
portions H and 12. A spacer sleeve I'l surrounds
the remainder of the cylindrical portion l2 and
45 preferably extends slightly beyond its end and
engages with a pressure washer l8 which is
' guided by the smallest cylindrical portion l3.
The inner or axle race I 9 of a. second anti-friction
bearing surrounds the smallest cylindrical por
50 tion. l3. ‘This assembly is clamped tightly to
- gether by a nut 20 which is threadedly engaged
with the threaded portion M of the axle. It is
preferred to introduce a lock washer 2| having
two fingers, one of which is engaged with a groove
55 in the cylindrical portion l3 to prevent the
At the outer end, the hollow hub is provided
internally with a cylindrical surface 35 for re- 25
ceiving the outer or hub race'36 (of the second
anti-friction bearing which has illu‘stratively the
bearing balls 37. It will be noted that this hub
race 36 is not clamped, and hence this second
anti-friction bearing assembly is able to adjust 30
itself while the wheel and axle are being brought.
together; and the end thrust is accepted by and
transmitted through the ?rst anti-friction bear
ing assembly.
These anti-friction bearings are illustrated as 35
having cage members 40; and the inner or ?rst
anti-friction bearing, adjacent the open or inner
end of the hub, is preferably provided with a
lubricant seal M ?xed to the hub race thereof;
and each bearing assembly is self-contained and 40
self-supporting against relative axial displacements of the axle and hub races.
'
'
The hub race 3| of the inner ory?rst anti-fric
tion bearing is pressed tightly against the abut
ment 32 by a pressure ring 45 which is guided 45
by the surface 30 of the hollow hub, and has an
inwardly extending portion closely ?tting but
spaced from the cylindrical portion ll of the
axle.
The pressure ring 45 is held in position by a 50
pressure cap. This pressure cap is manufactured
from ‘a triangular blank as shown in Fig. 2, nor
mally being of a mild steel which can be smoothly
drawn into shape. The drawing operation com

(a) of Fig. 2 relatively out'of ‘the plane of the
rest of the sheet of the blank, and thus drawing
that the ring 45 projects and the bottom of the
cup-like member 0 is never engageable with they
metal from the area adjacent the circle (a) to
form a cup (Figs. 3 and 4) which is deeper than
the distance from the circle (a) to the adjacent
end of the hub extension. It is especially to be
remarked that the ?rst anti-friction bearing is
side of the blank, along with operations for main
clamped tightly, rather than adjusted; so that all
assembly operations may be performed by a rela
talning or assuring to the three corners of the '
tively unskilled workman, without danger of hav

ing the bearing too tight or too loose.
to the plane of the area within the circle (a).
As a result of these operations, and the pre—
10
cedent or subsequent formation of an aperture
corresponding to the circle (17) of Fig. 2, the re
‘ silient steel cap of Figs. 3 and 4 is produced, hav
ing the peripheral wall (0) which preferably is
15 slightly conical to conform to the usual conical
external shape of the projecting portion 29 of ‘the
hollow hub, a fiat end portion (d) comprising the
portion of the blank between the circles (a) and
(b), and the three projecting ears (e) each of
20 which has an aperture. (I) which is illustrated as
rectangular to receive the correspondingly shaped
portion of a carriage bolt 50 (Fig. 1). These
bolts are passed through apertures 5| formed in
the corresponding spokes 26 of the wheel, so that
the nuts 52 are at the outer or exposed face of
the wheel and are readily accessible for the plac
ing or removal of locking keys, and for the plac
ing or removal of the nuts themselves. Thus,
these bolts may be tightened or released without
30 any access to the inner face of the wheel at all.
If desired, the extreme corners of the steel cap
may be bent over as shown by the bends 53 (Fig.
1) to retain the belts against undue axial move
ment with respect to the cap. It is particularly
pointed out that the presence of the gaps (9)
permits the use of a relatively thick piece of,
metal in the blank, while assuring a considerable
resiliency in the assembly,‘a'nd so that the clamp
ing is facilitated.
The pressure ring 45 provides a portion of a‘
40
groove which is open adjacent the cylindrical
portion l l of the axle. The remaining portion' of
this groove is provided by the portion (d) of the
cap. Within this groove is located a packing or
sealing material 55 which may be a simple or re
inforced felt washer, bearing against the cylin
drical'portion I I" and thus completing the seal of
the bearing structure and assembly against the
exit of lubricant. Lubricant may be supplied at
‘the closed end 2'! of the hub by the device 5811
lustrated.
_
.
In assembly for this illustrated form, the cap,
packing, and pressure ring are placed upon the
axle end. The anti-friction bearings are then
assembled upon the axle, and clamped tightly by
nut 20. The wheel is slid on, the hub race of the
second anti-friction bearing ?oating along the
surface 35, and the hub race of the ?rst anti
friction bearing being brought against the abut
ment 32. The pressure ring, packing, and cap are
aligned during this operation; and the nuts 52
are positioned and drawn tight. The depth of
the peripheral wall (0) is illustrated as less than
the total projection inward from the axially
aligned parts of the wheel structures (that is, the
sum of the axial length of the hub extension from
the inner surfaces of the spokes 26 or limiting
surface of the annular recess at the inner face of
the wheel, plus the projection 01' the ring 45),
so that the ears and cup wall effect a tight re
silient clamping; and, further, the parts are so
proportioned, as shown, that the combined axial
‘_ length of the hub race ‘30 and the pressure ring
45 is greater than the spacing of the abutment
32 from the inner end of the hub extension, so
-
The cap may be manufactured in quantity very
cheaply; and although of particular value when
employed with factory-assembled vehicles, it is
also capable of substitution for present or dam
aged equipment, as.a repair structure either with
or without the pressure ring 45 and packing 55. It is obvious that the invention is not limited to 15
the specific embodiments shown, but that it may
be employed in many ways within the scope of the
appended
claims.
