Improvements in the Construction of Tires for Vehicle Wheels.
I, PETER JENSEN, of 77 Chancery Lane, in the County of Middlesex, Chartered
Patent Agent, do hereby declare the nature of this invention, which has been
communicated to me from abroad by Gustav Podoll, Henry William Theis, Charles
James Fox, and Delbert Henry May, all of Number 612 Grand Avenue, in the
City and County of Milwaukee and State of Wisconsin, United States of America,
Manufacturers, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
suitable
The invention has for its object the production of a tire for vehicle wheels
practically incapable of puncture, and to that end it consists in providing a con-
tinuous hollow tube with a continuous tread exterior thereto, said tread being
composed of a series of composite strips consisting of thin cloth coated upon one
surface with ground emery or analogous granular material mixed with
adhesive solution, all of said composite strips being encased in an enclosing strip
of fabric with an outer sheet of thin rubber covering the latter, and all vulcanized.
together and to the said continuous hollow tube, all as hereinafter more particularly
set forth and illustrated in the accompanying drawings:
DESCRIPTION OF DRAWINGS.
Figure 1 is a section view of a vehicle tire embodying the said invention, and
showing a rounded tread.
Figure 2 is a similar view, illustrating the said invention applied to a tire having
a flat tread.
The said invention is particularly adapted for use on the tires of bicycle and
tricycle wheels, but is applicable to the wheels of other vehicles. Referring to
the drawings, A represents a hollow pneumatic tire tube of any preferred construc-
tion. Strips of thin cloth a a, are coated upon one surface with ground emery or
analogous granular material, mixed with any suitable adhesive solution, such as
rubber solution, there being any desired number of these strips, four being shown
in the present illustration; a strip of fabric, b, is arranged around the side and
outer parts of the composite strips a a described, with the side edges of said fabric
brought over the inner layer a of the coated cloth strips, and c represents an outer
layer of thin rubber surrounding the fabric b, the whole forming the tread C.
This tread is united to the tube A in any suitable manner, as by strips of solid
rubber B B, and the parts are all vulcanized together.
This tread which may be either rounded from side to side, as shown in Figure 1,
or flat as shown in Figure 2, is practically incapable of puncture, and hence there
is very little possibility of injury to the pneumatic tube A, in use. The said tube
may be attached in any preferred manner to any suitable wheel rim, and the entire
device will be found light, economical and useful.
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:-
A tire for vehicle wheels, consisting of a continuous hollow tube, with a con-
tinuous tread exterior to said hollow tube and composed of strips of thin cloth

with a suitable adhesive solution, a strip of fabric arranged around the described
emmposite strips and an outer sheet of thin rubber surrounding the said fabric,
completing the said continuous tread, and all vulcanized together to the said
continuous hollow tube.
