To all whom it may concern:

Be it known that I, Otis Ruggles Whittemore, a citizen of the United States, residing in Arlington, in the county of Middlesex and 5 State of Massachusetts, have invented a new Carriage for Roller-Coasters, of which the following is a specification.

Within the drum is a freely-hanging car C, sus- 25 pended from the axle D of the wheel. At the extremities of this axle are two freely-moving flanged wheels E, which run upon elevated rails F on either side, keeping the carriage upright when running straight away and con- 30 trolling its inclination as it sweeps around curves, as clearly shown in Fig. 2.
