WILLIAM A, 1MLA\X, QF DALLAS, TEXAS.
VEHICLE-WHEEL.Specification of Letters Patent: Patented Nov. 11, 1913.
Application filed July 30, 1912. Serial No. 712,222.To all whom it may concern:
Be it known that I, WILLIAM A. MIIAM, a
citizen of the United States, residing at
Dallas, in the county of Dallas and State
5 of Texas, have invented certain new and
useful Improvements in Vehicle-Wheels, of
which the following is a specification..
My invention relates to a new and use-
ful vehicle wheel, and relates more particu-
10 larly to the class of vehicle wheels, which
embody in their construction some means
for absorbing such shocks as are imparted
to the rim of the wheel during the travel
of the vehicle upon which the wheel is
15 mounted, thus protecting the occupants of
the vehicle against the frequent jolting to
which they would otherwise be subjected.
The object of the invention is to provide
,a vehicle wheel, which will have embodied
20 in its construction a plurality of radial
coiled springs, which will be adapted to
absorb either partially or entirely such
shocks as may be communicated to the rim
of the wheel during the travel of the vehicle
25 upon which the wheel is mounted.
A further object of the invention is to
provide a vehicle wheel of the character
described that will be strong, durable, sim-
ple and efficient and comparatively easy to
30 construct, and also one that will not be
likely to get out of order.
With these and various other objects in
view, my invention has relation to certain
novel features of the construction and oper-
35 ation, an example of which is described in
the following specification, and illustrated
in the accompanying drawing, wherein:
Figure 1 is a fragmentary front view of
the wheel with a certain portion thereof
40 shown sectionally. Fig. 2 is a transverse
sectional view taken upon the line X-X of
Fig. 1. Fig. 3 is a detail fragmentary sec-
tional view taken upon the line Y-Y of
Fig. 1.
45 Referring now more particularly to the
drawing, wherein like reference characters
designate similar parts in all the figures,
the numeral 1 denotes the hub of the wheel,
which is provided with the usual central
50 aperture 2. To each lateral face of the hub
1, there is bolted the middle portion of a
large circular metal plate 3, the two plates
3 being parallel and provided with central
apertures receiving the hub extremities..
55 The bolts connecting the plate 3 to the
hub 1 are designated by the numeral 5, andthe numeral 6 denotes a plurality of bolts
which holds the plates 3 in a proper spaced
relation at points approximately half way
between the centers of said plates and the S0
peripheries of the same. An annular off-
set 7 is provided in each plate 3 concentric
with said plate and spaced a short distance
from the periphery of the same. The two
offsets 7 serve to form two parallel rim por- 65
tions 8 upon the plates 3, the portions 8
being spaced from each other at a distance
somewhat greater than that between the
plates 3.
Between the plates 3 are provided a plu- 70
rality of radially mounted tubes 9, extend-
ing from the hub 1 to a point spaced slightly
outward from the offsets 7. Each of the
tubes 9 is formed partly integral with one
plate 3 and partly integral with the other, 75
the line of demarcation between the two
parts of said tubes being indicated in Fig.
3 by the numeral 10. Adjacent to the inner
extremities of each tube 9, a transverse par-
tition 11 is formed in said tube, through the 80
center of which partition is passed the inner
end of a rod 12. Each rod 12 is extended
centrally outward through the correlated
tube, and is made to project slightly beyond
said tube at its outer extremity, the inner 85
extremity of each rod is provided with a
nut 12a bearing upon the inner surface of
the partition 11, and the other extremities
of.the tubes 9 are made to project through
a resilient metal ring 13 of comparatively 90
thin material, concentric with the plate 3,
and contiguous at its lateral edges with the
portions 8 of said plate. A conical head
14, contiguous with the outer surface of
the ring 13, is provided upon each rod 12. 95
Upon each of the rods 12 there is mounted
a coiled spring 15 having its inner extremity
abutting against the correlated partition 11,
and its outer extremity against the inner
face of the ring 13. The coiled springs 15 zoo
will preferably have a diameter substan-
tially equal to the inner diameter of the
tubes containing said springs, so that the
springs are free to undergo expansion or
compression but will be restricted from 105
lateral displacement within their respective
tubes. The ring 13 carries a tire or tread
member 16 of hard rubber, the conical heads
14 of the bolts 12 being embedded in the
rubber tread 16 and serving to retain the 110
same. A pair of rings 17 of comparatively
soft rubber will be mounted between each1,077,994.
