lateral extension or is formed so that it will engage with or against a lip or abutment on the rim at a point which is so far removed from the said inner seating as to insure the locking of the ring to the rim solely by inflation stresses and to obviate the use of mechanical fastenings between the ends of the ring or ring-segments, or between the ring and rim. (2.) In a pneumatic-tired wheel having an inflation-locked retaining-ring; the use of a rim or felloe having an annular recess or channel which is adapted to receive the retaining-ring and is provided around its outer edge with the lip or abutment with which the laterally extended outer side of the said ring is adapted to be engaged, substantially as described and set forth. (3.) In rims for pneumatic-tired wheels, the combination with the split or segmental and detachable retaining-ring, of a rim having a hook-sectioned outer edge, into which the lateral outer flange or extension of the said ring is adapted to be engaged and locked by inflation in the manner and for the purposes described. (4.) A wheel-rim in which the annular recess B is bounded on the one side by a shoulder rising to the seating which is adapted to receive one edge of the tire-cover, and on the other side by a lip or abutment such as 8, the top of which lies in the same plane as the said seating, for the purpose described.
