Improvements relating to Tires for Vehicles.
I, HERBERT JOHN HADDAN, of the Firm of Herbert Haddan & Co., of 18,
Buckingham Street, Strand, W.C., Consulting Engineer, do hereby declare the
nature of this invention (a communication to me from abroad by Frederick
Stewart of 30, Broad Street, in the City of New York, United States of America,
Lawyer), and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement: —
This invention relates to rubber tires for vehicles and has for its object to
provide a simple and effective means for securing tires of this character within
a channeled metallic rim.
To this end the invention consists in certain novel features which I will pro-
ceed to describe and will then particularly point out in the claims.
In the accompanying drawings,
Figure 1 is a perspective view, partly in section, of a tire embodying the
invention, the same being shown in place in a rim constructed for its reception;
Figure 2 is a view partly in elevation and partly in central vertical section,
of a portion of a tire embodying the invention; and
Figure 3, is a transverse sectional view of the tire removed from the rim and
without its fastening devices.
In the said drawings, 10 indicates the tire proper, which is constructed of
rubber and is preferably of the form shown, having a rounded outer portion,
as indicated at 11, and diverging side portions 12 to a point within the flanges
of the rim, whereupon the sides converge, as shown at 13, to a junction with the
flat bottom portion 14 which forms the innermost part of the tire. This latter
part, as well as the inwardly converging portions 13, are preferably provided with
a covering 15 of some suitable fabric, such as canvas.
of the tire, located at or slightly inward from the junction of the sides 12 and 13,
At a point on each side
there is provided a groove or recess 10, preferably similarly contracted at its
nouth, as shown, and of a size sufficient to receive and enclose a retaining
vire. Immediately inward from these grooves and extending transversely of
he tire from side to side thereof, are located at suitable intervals a plurality of
etaining or anchoring pieces 17. These pieces are preferably flat and compara-
ively thin, as indicated in section in Figure 2 of the drawings, and their ends
xtend to the surface of the rubber of the tire at each side thereof and are
dapted to contact with the sides or flanges of the channeled rim. I also prefer
so construct these retaining or anchoring pieces that their ends are slightly
rned upward or outward toward the periphery of the tire, as indicated at 18.
This tire is employed in conjunction with a metallic rim 19, which is pro-
ded with outwardly diverging flanges 20, whereby a channel or groove is formed
hich provides a seat for the tire. The proportion of the parts is preferably
ch that the grooves or recesses 16 lie wholly below the outermost portions
the flanges 20 when the tire is in place. In order to retain the tire in posi-
n in this rim I employ two retaining wires 21. These wires ore

in the sides of the tire and rest upon the outer portions of the retaining pieces 17,
being held in position laterally by the flanges 20 of the rim and also by the
upturned ends 18 of the retaining pieces, when such upturned ends are employed.
It will be observed that, when the wires are in position, the lower portions of
the outer part of the tire extend downward to form ribs 22, which extend over
the wires 21 and cover and protect the same, abutting against the flanges of
the rim so as to more effectually enclose and protect the channels or grooves
and the wires located therein. The several elements of the tire may be assem-
bled in any approved manner employed in the assembling of wired on tires,
that is to say, the ends of the wires may be joined in any suitable manner, and
this done either before or after the placing of the tire in the rim.
When the several parts are assembled in the manner shown in Figure 1 of
the drawing, it is obvious that any force operating upon the tire to twist or tilt
the same laterally and thus throw it out of the rim will be resisted by the bear-
ing of the wires upon the retaining pieces, and, owing to the relative location
and arrangement of the parts, the tire will be firmly and effectually held in
place. The ends of the retaining pieces are moreover pressed against the
flanges of the rim in such manner as to effectually prevent creeping of the tire
and consequent injury thereto.
It is obvious that the details of construction may be modified without depart-
ing from the principle of the invention. For instance, although
prefer to
employ the flat retaining pieces 17 shown, which give a broad or extended
bearing upon the rubber, yet I do not limit myself to this particular form of
the retaining pieces, and while I deem it desirable to provide these retaining
pieces with upturned ends, yet this feature may under certain circumstances be
dispensed with. I therefore do not wish to be understood as limiting myself to
the precise details hereinbefore described and shown in the drawings.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination, with a channeled metallic rim, of a rubber tire fitting
within said rim and provided at each side with a continuous open groove or
channel, retaining pieces extending transversely of the tire immediately inward
from said grooves, and retaining wires located in said grooves and bearing on
the retaining pieces, substantially as described.
2. The combination with a metallic rim having outwardly diverging flanges
forming a channel, of a rubber tire having a correspondingly shaped inner
portion to fit said channel, an outer portion the sides of which are at an angle
to the inner portion and provided at each side along the lines of junction with
a continuous open channel or groove, said grooves or channels lying within
the outer peripheries of the flanges, retaining pieces extending transversely of
the tire immediately inward from said grooves, and retaining wires located in
said grooves and bearing on the retaining pieces, substantially as described.
3. The combination, with a channeled metallic rim, of a rubber tire fitting
within said rim and provided at each side with a continuous open groove or
channel, flat retaining pieces extending transversely of the tire immediately
inward from said grooves and each having an extended bearing surface, and
retaining wires located in said grooves and bearing on the retaining pieces,
substantially as described.
4. The combination, with a channeled metallic rim, of a rubber tire fitting
within said rim and provided at each side with a continuous open or groove or
channel, retaining pieces extending transversely of the tire immediately inward
from said grooves and having outwardly extending extremities, and retaining
wires located in said grooves and bearing on the retaining pieces adjacent to
their extremities, substantially as described.

page_text: 5. The combination, with a metallic rim having outwardly diverging flanges
forming a channel, of a rubber tire having a correspondingly shaped inner por-
tion to fit said channel, and an outer portion the sides of which are at an angle
to the inner portion, said tire being provided at each side with a continuous
open groove or channel located within the outer periphery of the flanges of the
rim and the outer portion of the tire extending inward in the form of ribs to
cover and protect said grooves, retaining pieces extending transversely of the
tire immediately inward from said grooves, and retaining wires located in said
grooves and bearing on the retaining pieces, substantially as described.
6. The combination with a wheel-tire having outwardly extending flanges
at each side, of the solid rubber tire provided with metal bars at the inner side,
and the endless wires passing around said tire and bearing against the projecting
ends of said bars, substantially as described.
