8 similar to the openings shown by Figs. 1,
2 and 3. In other respects the modified form
of the tire shown by Figs. 4 and 5 is identical
in structure with those of the preceding
5 figures.
The most essential feature of the present
improvements is what is termed a steel
breaker 17, consisting of a flat tube em-
bedded in the tire and continuing fully
10 around the same adjacent to the tread 6.
This breaker or tubular steel reforce is pref--
erably made by flattening a steel pipe and
then bending the flattened pipe in circular
form and disposing it in this shape in the
15 mold at the time the tire is formed, so as to
fully embed the same in the rubber or rub-
ber composition duringthe molding opera-
tion. This breaker or wheel reforce is dia-
metrically opposed to a steel band or hoop,
20 in that it is not intended to have a sensi-
tive resilient action, the essential object of
this interposed flat tubular means being to
equally distribute the shock or vibrations on
all cross sections throughout the body of the
25 tire, instead of affecting only a portion of
the cross sections of the tire as in that class
of tires which lack any means to assist in
holding up or bracing the sections or rein-
forcing means. By means of the improved
30 breaker located adjacent to the tread of the.
tire every cross section in the tire will take
care -of its proportionate share of the shock,
but the tread near the point of contact will
receive, as a matter of course the hardest
35 part of the. shock. The opening of this
breaker or wheel brace will be governed in
size according to the weight the tire is sup-
posed to carry, and as an additional func-
tion' the improved breaker will serve to
40 maintain the side walls of the tire more
straight on the outside, in view of the re-
sistance. in transverse directions set up by
the interposition of the said tubular ele-
ment. 'Furthermore, the improved breaker
45 or tubular wheel reforce cooperates with and
materially affects the several braces or re-
inforcing sections between the same and the
inner rim-engaging portions of the tire, and
at the same time the braces or reinforcing
50 sections are. free to set up a necessary cush-
ioning effect which is provided for by the
formation of the legs 12 and 16 in the two
forms of the tire, the said legs regularly
expanding and contracting lengthwise of the
55 .tire or around the latter, the greatest ex-
pansion of these legs occurring at the point
of contact and adjacent to the said point of
contact of the tread of the tire with the road
surface and throughout the length and
60 around the tire. This expansion and con-
traction is proportionately present so that
the whole tire is affected" and proportion-
ately contributes to the general resilient ac-
tion of the tire. The expansion of the legs
12 and 16 will depend upon the load orweight imposed upon the tire, but the im-
proved breaker or tubular tire bracing ele-
ment 17 will so equalize and distribute the
weight pressure affecting the tire as to per-
mit a predetermined size or extent of each 70
brace or reinforced cross section to sustain
considerable weight without distorting the
tire. In other words, the legs 12 and 16 of
the intermediate braces or reinforcing cush-
ioning sections will be prevented from cav- 75
ing in when subjected to severe shock and
caused to sustain the shock at the point of
contact of the latter with the resident dis-
tribution of the shock to each and every.
member of the intermediate braces embody- 80
ing the legs through the cooperation and
function 'of the breaker. A further 'impor-
tant advantage of this structure is that the
shock will be transmitted to all of the inter-
mediate braces or sections embodying the 85
legs 12 and 16, and a general coaction will
ensue throughout the tire structure, or the
several structural features of the improved
tire will act with unitary compensation and
equal distribution throughout the tire and 90
thereby produce an advantageous cushion-
ing effect, and at the same time the tire is
prevented from having any tendency to. lie
down or remain flattened when running at a
good speed, and particularly when turning 95
or rounding curves. The improved breaker
while not technically resilient or having a
spring action, will yield as a whole to con-
tribute to the compensation and to mate-
rially assist in the sustention and equal dis- 100
tribution of the weight stress which is due to
the flattened hollow structural character of
the breaker. This breaker will bend before
it will break and is also made strong enough
so that it will not be crushed or collapsed 106
during a hard shock imposed thereon. The
breaker also causes the tire to' pull much
easier as the expansion of the surface con-
tacting portion of the tire is prevented
from being as> great as in a tire without a 110
device of this character and in turning or
rounding curves the, breaker comes perma-
nently into play as an effective structural
feature to prevent lateral and irregular dis-
position of the several intermediate bracing 115
or reinforcing sections which give the tire
its cushioning action. In referring to the
flattened tube 17, as a "breaker," it is in-
tended to be understood that this device
breaks up any tendency to collapse, or irreg- 120
ular movement of the intermediate cushion-
ing elements of the tire, and also to break
up any disadvantageous action of varying
weight stresses that might tend to impair
the practical efficiency of the tire. The im- 125
proved tire also embodies wires 18 embed-
ded in the same at opposite sides of the cen-
ter of the inner rim-engaging portion to
assist in holding the tire in connection with
the rim of the wheel. 13941D
