'I do not Wish, therefore, to be limited to the construction which I have herein shown and described; but

What I do claim, and desire to secure by Letters Patentof the United States, is-f- 1. As an article of manufacture, a rollerskate Wheel comprising,` an annular Wheelbody A, trausversely-notched ball-casings B iitting into opposite sides of the Wheel-body A, the depth to Which said casings can be driven therein being limited by end iianges b, and means mounted in the Wheel-body A for engaging the transverse notches in the ball-casings to hold the ball-casings from falling,` out or turning in the wheel-body, substantially as described.

2. As an article of manufacture, a rollerskate Wheel comprising an annular Wheelbody A, having a keyWay 11, flanged ballcasings B fitting into the Wheel-body A, and a key 12 fitting into the keyWay 11, and having its ends 13 and 14 bent in to engage transverse notches 10 in the ends of the ball-casings 13 to hold the ball-casings B from falling` out of or turning in the wheel-body A, substantially as described.
