Improvements in and relating to Cushion Tires.
I, WEBBER GRANT KENDALL, a citizen of the United States of America, residing
at 209, Annington Street, Edgewood, in the County of Providence and State of
Rhode Island, United States of America, Gentleman, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The invention relates to that class of rubber tires commonly called " cushion
tires," and it is especially adaptable to the ordinary metal-tired wheel.
Heretofore, in this class of tires, it has been usual to provide a specially con-
structed rim in which to seat and confine the tire, which adds greatly to the cost
of construction and is otherwise objectionable; also great difficulty has been
experienced in providing efficient means by which the rubber tire may be firmly and
rigidly held upon the rim against, lateral strain, which is especially injurious to the
weaker parts of the average rubber cushion tire.
The present invention is particularly designed to overcome these difficulties,
and to that end it consists of a tire, preferably molded in sections, having an
interior longitudinal chamber extending at one or more points of its width toward
the tread of the tire and preferably at two points of its width toward its inner
periphery, and adapted to receive a clamping-band provided with one or more
upwardly-extending resistance means adapted to fit into the upwardly-extending
portion or portions of said longitudinal chamber, and preferably with two down-
wardly-extending resistance means adapted to fit into the downwardly-extending
tire⚫ being SO constructed
portions of the longitudinal chamber, said
as to permit the employment of securing bolts for attaching the tire onto the
wheel.
In the accompanying drawings,
Figure 1 is a side view of a vehicle wheel having the usual metal tire, showing
my improved cushion-tire applied thereto; Figure 2 a cross-section of a portion of
the same; Figure 3, a perspective view of a portion of one of the rubber tire
sections; Figure 4 a similar view of the end portions of two united sections of the
clamping-band; Figure 5, also a perspective view of said end portions, separated
to show the manner in which the sections are connected; Figure 6, a cross-section
of a portion of a wheel, showing a modification of my invention applied thereto;
Figure 7 a perspective view of a portion of the modified clamping-band; Figure 8,
another modification of my invention, and Figure 9 a perspective view of the
clamping-band employed therein.
The numeral 1 indicates a wheel which is provided with a metal tire 2, of the
usual form, set onto the rim or felly 3.
The rubber tire 4 is preferably composed of a series of sections, 5, each section
being preferably molded with a channel, 6, running the full length of the section.
This channel communicates with an interior longitudinal chamber, 7, having
upwardly and downwardly-extending chambers 8 which form hook-shape seats 9
and 10, respectively, for a suitable clamping-band.
The numeral 11 indicates the clamping-band, which is composed, preferably, of

page_text: with, and in lieu thereof the inner periphery of the tire is provided with a series
of holes 28 which register with the holes in the felly and metal tire, the securing-
bolts passing through the same to secure the tire onto the wheel. By dispensing
with the channel 20 I am enabled to also dispense with the depressions 23, at each
end of the chamber 21, and with the ribs 26, as all danger of the side edges of the
tire spreading will be obviated.
It will be noted that when the clamping-band is forced firmly to its seat, by
screwing up the nuts on the bolts, that a sufficient space in the tire above the
resistance means and the upper surface of the band will be formed to serve as a
cushion.
If desired, a lining, 29, of leather, canvas or similar material may be placed
in the hook-shaped seats as shown in Figure 2, to give additional stiffness to the tire
along that portion, but I prefer not to use it, as it is sufficiently stiff without it.
To apply my tire to wheels now in use, all that it is necessary to do is to remove
the bolts securing the metal tire to the felly and replace them with longer bolts,
and then proceed to place the rubber tire and clamping-band sections in position,
as heretofore described.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim; is:-
1. As an article of manufacture, a rubber tire having an interior longitudinal
chamber, said chamber being extended at one or more points of its width, in the
direction of its tread, and adapted to receive a resistance means, said tire being
constructed to permit access to its chamber.
2. As an article of manufacture, a rubber tire having an interior longitudinal
chamber, said chamber being extended at one or more points of its width in one or
more directions, as in the direction of the tread or the tread and wheel rim, and
adapted to receive a resistance means, said tire being constructed to permit access
to its chamber,
3. A rubber tire, having an interior longitudinal chamber, said chamber being
extended at two points of its width, in the direction of its tread, in combination
with a clamping-band and resistance means, whereby the tire may be secured onto
a wheel, and injury to the same, by lateral strain, is prevented.
4. A rubber tire, having an interior longitudinal cavity, said cavity being
extended, at two points of its width, in diametrically opposite directions, and having
a channel or slot opening from the inner periphery into said cavity, in combination
with a clamping-band provided with oppositely extending resistance means and
bolts whereby the band, and thereby the tire, may be secured onto the wheel.
