Improvements in and the Manufacture of Tires for Velocipedes or
other Vehicles and Rims or Felloes used therewith.
1 JAMES YATE JOHNSON of 47 Lincoln's Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this invention which has been com-
municated to me from abroad by John Haven Cheever of 15 Park Row New York
City in the United States of America Manufacturer 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 the manufacture of tires for velocipedes or other
vehicles and particularly to tubular or hollow tires adapted to be inflated by air
or gas under pressure.
The object of the said invention is to facilitate and cheapen the manufacture of
such tires and to provide simple and effective means for securing them in place on
the rim or felloe of the wheel.
The invention and the preferred manner of carrying the same into effect, can be
most conveniently explained in connection with the accompanying drawings, in
which Figure 1 is a cross-section of the improved tire, and Figures 2 and 3 are
similar sections illustrating modified constructions.
One feature of the invention is the formation of loops on the linen or canvas tube
through which a holding wire or band is passed for attachment of the tire to the
properly grooved or channeled rim of the wheel. The invention is preferably
carried into effect as follows:-
A. tube a is formed of linen, canvas or other suitable textile fabric and then
portions of the tube are taken in and by two parallel lines of stitching the external
loops or hollow beads (Figure 1) are formed on the side of the tube which is to
lie nearest to the rim. A rubber tube c is then inserted in the tube a and
vulcanized by means of live steam whose pressure forces the rubber tube against
The ends of the compound
and secures it permanently with the canvas tube a.
tube thus formed, are then spliced, making an endless rubber-lined tube. Over
this is vulcanized or cemented an outer covering or layer d of rubber which may
be lined with canvas on the under side.
The rim or felloe e to which the tire is to be applied is provided with parallel
grooves or channels corresponding with the loops on the canvas tube, and the tire
is secured to the rim by means of holding wires or bands which pass through the
loops and fit in the grooves of the rim.
The tire may be inflated by means of a tube having a suitable valve.
Instead of making the tire as a complete tube the tire may be made of
approximately semi-cylindrical form as illustrated in Figure 2.
This form of tire can be made of flat strips, and is therefore more easily
produced.
The loops or hollow beads are not necessarily formed on the canvas tube but
may be formed separately and applied thereto. For example a long canvas strip
may be taken and a loop or piping be made along each edge as shewn in Figure 2
and this be placed over a canvas tube before the outer tube or cover of rubber is
applied.
In Figure 3 the tube a is shewn as being provided with a loop formed of a single
strip attached to the outside of the tube, and adapted to hold a band g of con-
siderable width. In this case the rim e would be shaped to correspond as shewn in

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A hollow tire composed of layers of rubber and canvas or similar material, and
provided with a loop or loops for insertion of a holding wire, or wires or strip or
strips, substantially as herein before described.
2. A hollow tire composed of inner and outer layers of rubber, and an inter-
mediate layer of textile fabric provided with a loop or loops, adapted to receive a
holding band or wire for attachment of the tire to a grooved felloe, substantially as
hereinbefore described.
3. A hollow tire composed of a tube of rubber and a tube of textile fabric
provided with external parallel loops for holding wires, in combination with a rim
or felloe having grooves corresponding with the loops, substantially as hereinbefore
described.
4. The manufacture of hollow tires by making a tube of textile fabric, forming a
loop or loops thereon or attaching a loop or loops thereto inserting a rubber tube
and vulcanizing the latter by steam admitted under pressure to the interior thereof,
splicing the ends of the compound tube thus formed, and covering the same with a
layer of rubber, substantially as herein before described.
