JAMES G. POE, OF DALLAS, TEXAS, ASSIGNOR OF ONE-HALF TO ANDREW B. SMALL, OF
DALLAS, TEXAS.
EMERGENCY-TIRE.Specification of Letters Patent.
Patented Dec. 25,1917.
Application fled August 30, 1917. Serial No. 188,983.
To all whom it may concern:
Be it known that I, JAMES G. POE, a citi-
zen of the United States, residing at Dal-
las, in the county of Dallas and State of
5 Texas, have invented certain new and use-
ful Improvements in Emergency-Tires; nd
I do declare the following to be-a full, clear,
and exact description of the invention, such
as will enable others skilled in the art to
10 which it appertains to make and use the
same.
This invention relates to improvements in
automobile tires and has for its object to
provide a simply constructed and inexpen-
15 sive device of this character which may be
easily applied on the road in case of emer-
gency, and to this end, the invention resides
in the novel features of construction and
unique combinations of parts to be herein-
20 after fully described and claimed, the de-
scriptive matter being supplemented by the
accompanying drawing which forms a part
of this specification and in which:-
Figure 1 is a side elevation partly in sec-
25 tion showing the improved tire applied to
an automobile wheel;
Fig. 2 is a side elevation of the tire de-
tached;
Fig. 3 is a transverse section of Fig. 1
30 on the plane of the line 3-3 thereof; and,
Fig. 4 is a detail section of the meeting
ends of the tire showing more particularly
the manner in which these ends are joined
to the auxiliary rim which carries the tire
35 proper.
In the drawings above briefly described,
the numeral 1 designates a common type of
automobile wheel having the usual felly 2
and rim 3, these parts having the well known
40 opening 4 which ordinarily receives the
valve stem of a pneumatic tire. In the pres-
ent instance, however, the opening 4 is uti-
lized to receive a fastening stud which pre-
vents creeping of the emergency tire upon
45 the rim.
The improved tire includes a body 5
formed of cushioning material such as solid
rubber and a split ring 6 assembled with
said body and formed of spring metal, said
50 body being split in line with the split of
said ring. By reference to Fig. 2, it will
be observed that the ring 6 is normally con-
tracted so that its ends overlap, it being
thus necessary to expand the entire deviceand thereby place it under tension before 55
it can be applied to the rim 3, this tension
serving to frictionally hold the device upon
the wheel.
In the present embodiment of the inven-
tion, the ring 6 is in the form of an auxil- 60
iary rim having side flanges 7 which receive
the base of the cushion tire 5 therebetween.
It will be understood, however, that the ring
6 may be of any other suitable form and as-
sembled in any preferred manner with the 65
cushioning body 5.
Any preferred means may be employed
for securing the body 5 to the ring 6, but
for illustrative purposes I have shown a
pair of reinforcing wires 8 passing through 70
the base of said body and having their ends
bent laterally at 9 and secured to the ends
of said ring by brazing or by any other
suitable means.
Employed in connection with the features 75
of construction above described, is a thread-
ed, stud 10 which extends inwardly from
the ring 6 at a point spaced nearer to one
end of said ring than to the other end there-
of, this stud being adapted for passage 80
through the opening 4 as above suggested,
after which a nut 11 will preferably- be
threaded on said stud, and if desired, a
cotter pin or the like 12 may be employed
for locking said nut against accidental re- 85
moval. By locating the stud 10 where indi-
cated, the tire may be more easily applied
to the rim of the automobile wheel, without
the necessity of jacking the car up, since the
wheel may readily be rolled upon the tire, 90
due to the split formation thereof.
In applying the device, the same is ex-
panded as it is passed over the rim 3, the
ends of the device finally coming in contact
when it is totally applied. Due to the fact 95
that the auxiliary tire is expanded, as it is
applied, it will effectively grip the rim,
since it is placed under high tension. The
tire will thus remain in place and will be
of great advantage in case of emergency. 100
From the foregoing taken in connection
with the accompanying drawing, it will be
obvious that although the improved tire
is of simple and inexpensive:.:onstruction,
it will be highly efficient and' durable for 105
the purposes intended, and since probably
the best results are obtained from the spe-
cific details of construction shown and de-1,251,277.
