Improvements in Pneumatic Tires for Bicycles and similar
Vehicles.
"
I, JOHN ROBINSON MOORE, a citizen of the United States residing at 11 Lee
Avenue, in the City of New London, County of New London, and State of
Connecticut, U.S.A. Machinist, 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 :-
This invention relates to tires for bicycles and similar vehicles, and particularly
to what are known as tubular or pneumatic tires; and the object thereof is to
provide means for securing such tires to the rims of the wheels with which they
are connected.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which
Fig. 1 is a central longitudinal section of a portion of a tire and the rim of the
wheel with which it is adapted to be connected, said tire and rim being provided
with my improved means for holding the tire in place, and
Fig. 2, a bottom plan view of a section of the device which I employ for holding
the tire in position.
In the drawing forming part of this specification A represents an ordinary
tubular tire which is composed of rubber and canvas, or any desired material;
and B, the rim of the wheel with which the spokes are connected, said spokes
being not shown; and in the practice of my invention, I secure to the outer
surface of the rim B, a plate D, of steel or other suitable metal which is provided
with numerous perforations and outwardly directed teeth or projections as shown
at d, the teeth or projections being formed by puncturing the metal strip from the
inner side outwardly in such manner that the edges of the apertures project as
at d, or suitable outwardly directed projections may be formed by making
indentations on the inner surface by means of a punch or other device without
perforating the metal strip D.
It will be understood that the rim B, is segmental in cross section, or provided
with a groove in its outer surface in which the tire A, fits and said strip D is
secured in the bottom of said groove, and corresponds in form thereto, and said
strip is secured to the rim in any desired manner, after which the tire A is sprung
into position, and said tire will be securely held in position by the outwardly
directed teeth or projections d which project into the material thereof as will be
readily understood, and as shown in Fig. 1.
By means of this construction, the tire will be held securely in place without the
employment of any other means or devices, and experience has shown that this
method of connecting the tire with the rim is superior to any now in use.
My invention is not limited to the shape of the rim, or to the shape of the
strip D in cross section; and I reserve the right to make all such alterations
therein, and modifications thereof as fairly come within the scope of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
1. The combination with the rim of a wheel of a bicycle or similar vehicle, of a
strip of metal which is secured to the outer surface thereof, and which is provided

page_text: with numerous outwardly directed projections or teeth which are adapted to hold
the tire in place, substantially as shown and described.
2. The herein described means for securing the tire of a bicycle or other vehicle
in place, which comprises a strip of metal which is secured to the outer surface of
the rim of the wheel and over which the tire is adapted to be placed, said strip of
metal being provided with numerous outwardly directed teeth or projections,
substantially as shown and described.
3. The combination with the rim of a wheel of a bicycle or other vehicle, of a
strip of metal which is secured thereto, and over which the tire is adapted to be
placed, said strip of metal being provided with numerous outwardly directed teeth
or projections by means of which the tire is held in place, substantially as shown
and described.
