JOHN SHARP, OF BEAUMONT, TEXAS.
SPRING-WHEEL.988,952. Specification of
Application filed March 21
To all whom it may concern:
Be it known that I, JOHN ShARP, a citizen
of the United States, residing at Beaumont,
county of Jefferson, and State of Texas, have
5 invented a new and useful Spring-Wheel, of
which the following is a specification.
My invention relates to vehicle wheels
which are equipped with a solid tire and one
of the objects of my invention is to provide
10 a wheel of the character described with a
simple form of elastic support.
Another object of my invention is to pro-
vide a wheel of the character described
which is simple and economical in construc-
15 tion and which has its parts so arranged that
they are readily accessible for dismounting.
Other objects and advantages will appear
as hereinafter described.
Referring to the drawings: Figure 1 is a
20 side elevation, partly in section, of a wheel
embodying my invention. Fig. 2 is a section
on line x2-x2 Fig. 1. Fig. 3 is a view of the
inner face of the hub plate.
1 designates a solid tire of rubber or other
25 similar material seated within a groove
formed in a sectional rim 3. Each section 3'
of the rim 3 is provided with a pin 4 which
projects inwardly therefrom into a perfora-
tion 5 in the felly 6. The perforation 5 ex-
30 tends through a round boss 7 formed on the
inner side of the felly 6 and the inner end of
the perforation is threaded to receive the
threaded outer end of a spoke 8. The inner
end of each spoke 8 is threaded and is freely
35 movable radially in a perforation 9 in the
hub 10, the threaded end of the spoke being
engaged by a nut 11 held in fixed position in
the hub by the walls of a recess 12 therein.
The hub 10 is provided with a plate 13
40 screwed to the face of the hub which closes
the open side of the recess 12 and has exten-
sions or lugs 14 formed with a recess half
the diameter of the spoke for receiving the
spoke, the hub being also provided with cor-
45 responding extensions 15 so that each spoke
is embraced between an extension 14 and 15,
thereby preventing dirt and grit from enter-
ing the recesses 9 and 12 in the hub. Within
each perforation 5 and between the outer end
50 of each spoke and the corresponding pin 4
on the rim 3 is a coiled compression spring
15, the tension of which may be regulated by
changing the radial position of the spoke 8,
a nut 16 being formed on the spoke 8 for
55 engagement by a suitable wrench or other
engaging means.1,

1910. Serial No. 550,767.
The spokes are secured in a desired posi-
tion by means of a jam nut 17 which is pro-
vided with a sleeve 18 which fits over the
boss 7. Each boss 7 is provided with an b0
opening 19 through which the spring 15
may be inserted to its proper position be-
tween the end of the spoke and the adjacent
pin. The sleeve 18 on the nut 17 is made
of sufficient length to cover the opening 19 65
when the jam nut 17 is tightened against
the end of the boss 7. The jam nuts 17 are
also for the purpose of keeping the felly 6
in fixed position concentric with the hub.
The adjacent ends of the sections 3' are sup- 70
ported on the felly 6 by bowed springs 20
which span the joint between the sections 3'
and have their ends 21 pressing against the
sections 3'. The central or bowed part of
each spring 20 rests within a recess 22 in the 75
felly 6. To prevent displacement of the
springs 22, each spring is provided with a
pin 23 which fits within a perforation 24 in
the felly.
The outer side of the grooved portion of 80
the felly 6 is of less diameter than the inner
side so that the tire and rim sections may be
readily assembled, a circular rim or plate
25 is fastened to the outer side of the felly 6
by means of screws or bolts 26. The plate 85
25 and the corresponding extension on the
felly 6 serve to assist in keeping the rim
sections and tire in place and to also, to a
certain extent, prevent dirt from entering
between the rim sections and the felly. The 90
plate 25 and the corresponding extension
on the felly 6 are provided with rounded
lips or lugs 27, 28, respectively, which assist
in preventing foreign matter entering the
joint between the adjacent rim sections 3'. 95
What I claim is:
1. A spring wheel for vehicles, compris-
ing a solid tire, a rim supporting said tire
formed in sections, a felly spaced apart from
the rim and having perforations therein, said 100
felly having recesses on the outer surface
thereof, a hub, spokes extensibly mounted in
said hub and having their outer ends extend-
ing into perforations in said felly, coiled
springs in said spoke receiving perforations 105
between the ends of said spokes and the rim,
and bowed springs seated in the recesses in said
felly and secured thereto intermediate said
spokes, said bowed springs being arranged
to span the break between the sections of 110
said rim and having their ends engaging
the ends of the adjacent sections of said rim.
