Fig. 8, the interior periphery of the neck
11 does not contact the' axle 2, but is spaced
slightly apart therefrom, which allows the
axle 2 a slight movement in a vertical plane
6 as will later be seen.
It is seen that the universal joint 6 is
adapted to revolve with the axle 1 and
transmit the power of said axle to the axle 2.
As will later be seen, the member 9 of the
10 universal joint is subjected'to a very slight
movement out of its straight line drive.
There should be just enough 'looseness in the
meshing of the teeth 9 and 10 to compensate
for the difference in change of the pitch
15 necessarily encountered in this type of uni-
versal joint, when the said joint is* sub-
jected to.its 'slight changes in line drive.
The axle housing is seen enlarged and
formed into an elongated form of casing
20 member as indicated by the numeral 14.
The axle 2 is journaled in a bearing block
15 contained in the housing 14. The op-
posite end walls of said housing have ver-
tical grooves or slots 16 formed in their
25 interior faces. The bearing block 15 has
formed-on its opposite sides and adjacent
to the slots 16, integral guide pins 17, said
pins being adapted to a slidable up and.
down movement in the grooves 16. Upon
30 the top face. of the bearing block 15 are
formed integral lugs 18, said lugs being
adapted to retain a number. of coiled
springs or similar resilient members 19.
The upper face of the housing 14 has
'35 formed therein a large aperture 20 of rec-
tangular shape. This aperture forms a
guideway for and receives the bed block 21.
The bed block 21 receives and substantially
carries the usual channeled frame 22 upon
40 which is carried the body of the car.
The housing 14 has formed in its outer
side wall an elongated slot or aperture 23,
as best shown in Fig. 3. The axle 2 carries
a float bearing 24 which is mounted in 'this
4 slot and adapted to reciprocate therein.
The member 24 has an integral plate 25 of
rectangular shape, which is. adapted to lie
in close contact with the interior wall of the
casing and close the aperture 23. An ex-
50 terror flanged portion 26 adapts the mem-
ber 24 to be guided within the aperture 23.
The function of the member 24 and integral
plate 25 is to close the opening 23 against
dust occasioned and encountered from use
6 on the road.
It is seen how the float bearing 24, car-
ried by the axle 2 and retained in the slot
23, is subjected to a vertical movement
through the said slot as the axle vibrates
ea under its load and road irregularities. In
road vibration the axle 2 will have the
universal joint as a center and tend to de-
scribe an arc at its outer end. This are
is limited by the aperture 23 in the hous-
65 ing 14; it is therefore seen that the move'meant of the outer end of the axle 2, about
an arc, is very slight. 'Provision,.however,
is made in the member 24 to prevent the
axle binding and straining said member.
The interior periphery of. the aperture 70
in the member 24 is not cylindrical in form
but is modified to' accommodate the slight
pivotal or rocking movement' of the axle
in said aperture,. incident to said axle's
vertical movement about the universal Th
joint 'as a center. The numeral 25 indi-
cates the axially flared' aperture above re-
ferred to, as best shown in Figs. 3 and 5.
The bearing block 15, having a resilient
and flexible suspension, is not provided 80
with such an aperture as is carried by the
member 24.
The bearing block 15, reference being had
to Fig. 4, carries, on its lower portions an
integral hanger bracket 26. A pair of 85
bolts 27 is carried in the lower wall of the
housing 14 and extend through the bracket'
26' where the heads 28 of said bolts ' nor-
mally lie in contact with the under face of
the bearing block 15. Coil springs 29 are 90
carried by the bolts and confined between
the bracket 26 and heads of said bolts.
Similar resilient members 30 are confined
on the lower extremity of the bolts 27.
The purpose of the hanger bracket is, upon 95
the upward movement of the axle, to bring
the resilient members confined on the bolts
27 into action and thereby assist in carry-
ing the load sustained by the axle.
The foregoing description of the assembly 100
of elements contained in the housing 14, es-
tablishing a resilient and flexible suspension
of the axle and ground wheel whereby the
road and motor' vibration' are absorbed
directly through the resilient axle rather 105
than distributed through the axle housing
and thence through the elliptical springs to
the vehicle body as is the case with the pres-
ent methods.
As the pressure is upward on the axle 2, 110
the upper springs will support practically
all the load; hence their greater number and
size as compared to the lower spring mem-
bers.
In some cases it will be found preferable 115
to eliminate the last mentioned springs 30.
In such case the housing 14 will have the
appearance as illustrated in' the several
views exclusive of Fig. 4, said' figure, in
fact, being only a modified form of the in- 120
vention.
The application of the principle herein
embodied and claimed is extended to the
front wheels and axles of a vehicle. Figs.
.9 and 10 illustrate such application. The 121
usual steering knuckles of a front axle 31
. are removed and the housing 14 substituted.
In this case the usual steering arm would be
integral with the housing 14, as indicated
by the numeral 32. This would adapt the 132
