COMPLETE SPECIFICATION.
Improvements in Pneumatic Tires for Bicycle or other Vehicle
Wheels.
I RICHARD PATTISON, Tinsmith residing at 206 W. 24th Street, in the City
County and State of New York U.S.A. 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 improvements in pneumatic tires for bicycle or other
vehicle wheels; the object of the invention being to provide an article of this
character which will be so constructed as to be practically non-puncturable through
the tread thereof to the pneumatic portion. The tire will be light in weight,
inexpensive and durable, and it will be susceptible of quick attachment to the rim
of a bicycle or other wheel and its tread can be repaired or renewed without in any
way injuring or disturbing its pneumatic portion.
The invention will be hereinafter fully described and specifically set forth in the
aunexed claims.
In the accompanying drawings forming part of this Specification :
Fig. 1 is a side elevation of my improved tire.
Fig. 2 is a side elevation partly broken away of a portion of the tire, illustrated
in full size and attached to the rim of a wheel.
Fig. 3 is a cross sectional elevation taken on a line x-x of Fig. 2.
Fig. 4 is a perspective view of a portion of the tread of the tire, and
Fig. 5 is a cross sectional elevation of the pneumatic portion of the tire, having
its tread removed.
In the practice of my invention, I construct a pneumatic tube A, of rubber or
other flexible material and form integrally therewith the ordinary tubular
projection a, to which is secured any suitable feed valve a', through which air is
adapted to be pumped into the annular chamber a², by a hand or other air pump
in the customary manner. The outer or tread portion 1, of the tube A, is
thickened, and flattened upon its inner surface but its outer surface is convex in
cross section. Into and around this said outer or tread portion is formed an
annular dove-tailed groove 2, and into the side walls of this groove, annular
grooves 3, are formed whereby a substantially T-shaped groove is provided which
is adapted to receive and retain a metal ring B, and a detachable tread C, said
tread C, is composed of rubber or other flexible material and it is dove-tailed in
cross section, its side walls exactly registering with the inwardly inclined side walls
of the groove 2, of the tire A, and its inner surface bearing upon the periphery of
the metal ring B.
The ring B, is preferably composed of spring steel but other material of sufficient
resiliency and strength may be used; this said ring is encased in a covering b, of
fabric, preferably cotton, in order to supply a surface adapted to take a coating of
cement which will be used to hold the parts together.
In order to lighten the tread C, and also to increase its resiliency, it is provided
with a series of annular grooves c', which form annular chambers and act as
cushions when the parts are assembled, and admit of very easy riding, but the
walls c', have sufficient strength to prevent the tread C, from becoming useless
should one of the grooves c, be punctured; to further lighten and increase the
resiliency of said thread one or more of the annular walls c', may have formed
therethrough notches or openings . The tread may also supplied upon its outer

page_text: surface with cross grooves or corrugations c³, to facilitate traction upon smooth or
wet surfaces.
In assembling the parts, the covered ring B, and the grooved tread C, are
tightly cemented within the groove 2, and to each other whereby a durable tire is
produced having its pneumatic portion thoroughly protected from the danger of
puncture directly through the tread thereof. After assembling the said parts, the
tire is attached to therrim B, of any suitable wheel and inflated in a manner
common to all pneumatic tires.
I do not confine myself to the specific details of construction herein described
and shown, as I believe that under the scope of my invention I am entitled to
make slight modifications.
...
Having now particularly, described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what 1
claim is :-
1. A tire for bicycle or other wheels comprising an inflatable tube, a spring
metal ring and an independent flexible tread surrounding same, these said parts
being cemented to each other, substantially as shown and described:
2. In a tire for bicycle or other wheels, the combination of a grooved pneumatic
tube, a spring metal ring and a removable cushioned tread, substantially as shown
and described.
3. In a tire for bicycle or other wheels, the combination of the grooved
pneumatic tube A, the spring metal ring B, and the removable cushioned tread C,
substantially as shown and described.
4. In a tire for bicycle or other vehicle wheels, the combination of an inflatable
tube having a thickened outer surface with a substantially T-shaped and dove-
tailed annular groove therein, and a fabric covered spring metal ring and a grooved
tread of flexible material, these said parts being cemented within the said T-shaped
groove and to each other, substantially as shown and described.
5. In a tire for bicycle or other vehicle wheels the combination of the inflatable
tube A, having the T-shaped groove in its thickened outer surface, and the
spring metal ring B, having a coating of fabric b, thereon and the dove-tailed
tread C, having annular grooves upon its inner surface, substantially as shown and
.described..
6. The combination of a pneumatic tube having a thickened outer surface with a
dove-tailed groove therein which is in engagement with a metallic ring having a
coating of fabric thereon and a cushioned removable tread; with a rim or felly of
a-wheel, substantially as shown and described..
7. In a tire for bicycle or other wheels, the combination of an inflatable tube
having a thickened outer surface..within an annular, groove therein; with a fabric
covered spring metal. ring and a cushioned tread of flexible material; these latter
parts being cemented to each other within the said groove, substantially as shown
.and described..
'
8. The combination of a pneumatic tube having a thickened outer surface with
an annular groove therein; with a fabric covered, spring metal ring and a flexible
-tread- having annular grooves therein. and notches or openings through the walls
separating said grooves, and cross.corrugation.upon its outer surface, the said parts
being cemented to each other within the groove of the pneumatic tube, substantially
as shown and described.
