To all whom it may concern:
Be it known thatwe, ALEXANDER T. BROWN and GEORGE F. STILLMAN, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Tires for Vehicles, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention is an improvement in in flatable, or what are known as pneumatic, wheel tires for cycles and other vehicles.
The primary object of the invention is to provide a tire which, while possessing the resiliencyand life of what are technically known as true, or high grade, pneumatics, may be readily and easily detached from or applied to the rim of a wheel.
The improvement subject of our application and by which this object is realized involves as its chief characteristicsfirst-, an exteriorly grooved rim with divergent side edges or flanges, and second a tire comprising, or confining, an inflatable tube, seated and contained partly within the grooved rim, and made rigid or non extensible circumferentially along two lines on opposite sides which lie within the groove, below the edges but above the bottom or deepest part of the same.
