JOSEPH D. INGRAM, OF WASHBURN, TEXAS.
VEHICLE-WHEEL.1,068,660.
Specification of Letters Patent.
Application filed November 20, 1911. Serial No. 661,233.
To all whom it may concern:
Be it known that I, JOSEPH D. INGRAM.
a citizen of the United States, residing at
Washburn, in the county of Armstrong and
5 State of Texas, have invented a new and
useful Vehicle-Wheel, of which the follow-
ing is a specification.
This invention relates to spring wheels for
vehicles, one of its objects being to provide
10 a wheel of this type having all of the ad-
vantages of the ordinary wheel provided
with a. pneumatic tire, there being a novel
arrangement of springs arranged within the
rim portion of the wheel and adapted to be
15 placed simultaneously under compression
when the wheel is subjected to a load or is
jolted.
A further object is to provide a wheel of
this type all working parts of which are
20 concealed and are protected from dirt and
moisture.
Another object is to provide a wheel hav-
ing improved means for attaching a resili-
ent tire thereto.
25 A further object is to provide improved
means for securing the wheel to an axle.
With the foregoing and other objects in
view which will appear as the description
proceeds, the invention resides in the com-
30 bination and arrangement of parts and in
the details of construction hereinafter de-
scribed and claimed, it being understood
that changes in the precise embodiment of
the invention herein disclosed can be made
35 within the scope of what is claimed, with-
out departing from the spirit of the inven-
tion.
In the accompanying drawings the pre-
ferred form of the invention has been shown.
40 In said drawings: Figure 1 is a view
partly in side elevation and partly in sec-
tion of a wheel embodying the present im-
provements. Fig. 2 is an enlarged trans-
verse section through a portion of the wheel.
45 Fig. 3 is an enlarged section on line A-B
Fig. 1. Fig. 4 is an enlarged side elevation
of a portion of the rim and showing one of
the tire tightening devices. Fig. 5 is an en-
larged longitudinal section through the
50 means employed for connecting the wheel to
a spindle. Fig. 6 is a section on line C-D,Fig. 5, the locking lug and the spindle be-
ing shown in elevation. Fig. 7 is an en-
larged elevation of the nut used in securing
the wheel to a spindle. 55
Referring to the figures by characters of
reference 1 designates the tubular rim of
the wheel, the same having an annular slot
2 in the innermost portion thereof, there
being parallel annular flanges 3 along the 60
walls of the slots and extending inwardly
toward the center of the wheel. Oppositely
disposed similar disks 4 are riveted or other-
wise secured to these flanges and each disk
is provided, at its center, with a large open- 65
ing 5. A hub 6 is keyed or otherwise se-
cured to an axle 7 and has an exteriorly
screw threaded tubular extension 8 fitted
on the axle and projecting through and en-
gaging the walls of an opening 9 formed 70
in the center of the middle disk 10 of the
wheel. This disk is preferably hexagonal
and is clamped upon the hub 6 by a hub
section 11 which is screwed onto the exten-
sion 8, said section being attached to the 75
disk 10 and hub 6 by means of bolts 12 ex-
tending through them. A screw cap 13 may
be placed in engagement with the projecting
end portion of extension 8, as shown in
Fig. 2. 80
A series of openings 14 are formed in the
middle disk 10 close to the hub 6 and ex-
tending through these openings are connect-
ing bolts 15 secured to the disks 4 close to
the central openings 5 therein. These bolts 85
not only constitute connections between the
middle portions of the'disks 4 but also serve
to secure flexible disks 16 to the disks 4,
said flexible disks being formed of rubber
or other suitable material and being ex- 90
tended around the hub 6 and the hub sections
11 respectively so as to. prevent the admis-
sion of dust or moisture to the openings 5.
An- ear or extension 17 is formed at each
angle of the middle disk 10 and is formed, 95
in opposed faces, with sockets 18 each of
which contains a thrust ball 19 and a larger
spacing ball 20, the last mentioned ball being
adapted to contact with the adjacent disk 4
and thus hold the middle disk 10 spaced loo
therefrom.
A link 21 is pivotally connected to eachPatented July 29, 1913.
