JOSEPH L. SPOONTS AND EDWIN M. EUBANK, OF BALLINGER, TEXAS.
WHEEL.Specification of Letters Patent. Patented Apr. 11, 1911.
Application filed September 11, 1909. Serial No. 517,187.To all whom it may concern:
Be it known that we, JOSEPH L. SPOONWs
and EDwIN M. EUBANK citizens of the
United States, and residents of Ballinger, in
5 the county of Runnels and State of Texas,
have invented certain new and useful Im-
provements in Wheels, of which the follow-
ing is a specification.
Our invention is an improvement in
10 wheels, and consists in certain novel con-
structions and combinations of parts herein-
after described and claimed.
The object of the invention is to provide
a wheel having a pneumatic tire, but where-
15 in the tire will be so placed that it will not
Contact with the ground, thus reducing the
wear to a minimum, and preventing punc-
tures and like injuries.
Referring to the drawings forming a part
20 hereof, Figure 1 is a longitudinal section of*
the wheel, and Fig. 2 is a transverse section.
The embodiment of the invention shown
in the drawings consists of an auxiliary
wheel or disk composed of a hub 1, which is
25 connected to the felly 2, by spokes 3, the hub
being provided with the usual opening 1a for
receiving the axle. A flat rim 2a is seated
on the felly and near its center the flat rim
is provided with spaced annular ribs 2b be-
30 tween which is arranged a transversely
curved or concave rim 4a supporting a pneu-
matic tire 4. A pair of annualr plates 5 are
arranged outside of the tire, the inner edges
of the plates being flanged as at 6 for engag-
35 ing the tire, and a ring 7 is secured between
the said inner edges by bolts 8, which pass
through registering openings in the plates
and the ring, and the inner edge of the ring
also engages the tire, the flanges and ring
40 forming a rim for engaging the said outer
surface. A third rim 9 is provided with an
annular rib 10 which is received between the
outer edges of the plates, and is secured
therebetween by bolts 11 traversing the
45 edges and rib, and a solid tire 12 is seated
in the said rim. The rib 10 and the ring 7
are of equal thickness, and space the plates
5 apart to form an annular space therebe-
tween for a purpose to be presently de-
50 scribed. A disk or cheek piece 13 is ar-
ranged on each side of the hub, and secured
thereto by bolts 14, passing through the
cheek pieces and spokes, and beyond the
pneumatic tire the cheek pieces are offset
55 inwardly as at 15 and engage the outer
faces of the plates 5. At suitable intervalsthe cheek pieces are provided with openings,
and the plates with registering openings of
larger diameter and bolts 16 pass through
the openings for securing the said parts in 60
sliding engagement. Springs 17 are ar-
ranged within the annular space between the
plates and connected at one end to the said
bolts, and at the other to eyes 18 in the
rim 9. The cheek pieces are also provided 65
with central openings 20, which register
with the opening la of the hub.
The improved wheel is made of any suit-
able material, and of any desired propor-
tions, and is assembled as follows: The 70
plates 5 are bolted together, with the ring 7
and the rim 9, both of which are prefer-
ably of wood, in place, after the springs
have been attached. The cheek pieces are
then secured in place, and the wheel is ready 75
for use.
It will be evident from the description,
that the improved wheel is very simple in
construction, easily assembled and disassem-
bled, and that the pneumatic tire is entirely 80
protected from external violence, unless such
violence is sufficient to wreck the wheel. The
advantages of the pneumatic tire are re-
tained and utilized, with all of the disad-
vantages eliminated. In addition to the re- 85
silience imparted by the pneumatic tire,
there is the resilience of the solid tire, and
of the springs 17. In use, the solid tire en-
gages the ground, and a considerable portion
of the jars and jolts are absorbed by the said 90
tire. The auxiliary wheel is permitted a
considerable extent of radial movement with
respect to the frame, by the pneumatic tire
and the said tire absorbs the shocks which
are too great for the solid tire. The open- 95
ings in the frame through which pass the
bolts 16, are of much greater diameter than
the registering openings in the cheek pieces,
so that the frame is movable radially of the
cheek pieces and also angularly with respect 100
thereto. The springs which are tangential
to the wheel, are for the purpose of nor-
mally retaining the frame and cheek pieces
in the same relative angular position with
respect to each other. 105
The improved wheel consists broadly of
an inner and an outer wheel, the said wheels
being movable radially and angularly with
respect to each other, and yielding means for
retaining them in normal position. The 110
wheel might also be described as a wheel
comprising a wheel, a ring concentric with989,437.
