    • 25,059. Mitchell, T. Nov. 10. Theatrical appliances. -Relates to a crawling dummy figure for ventriloqual or stage purposes, and consists in giving movement to the limbs, head, and back portion of the figure as it travels along the ground. The head, body, and limbs of the figure are carried by a frame a, Fig. 1, in which are bearings for an axle b with wheels c attached, which rotate when the figure is drawn or propelled along the ground. The legs are controlled by cranks d on the wheels c through connecting- rods e attached to, and housed in, the legs. The arms are operated by levers l, l through link-work operated by sliding and rocking connecting-rods f actuated by the crank-pins d. These rods slide through bearings g pivoted at h. The rear part v of the figure is pivotally mounted at v and rocked by link-work operated by a crank on an upper shaft r . This shaft is driven by chain gearing from the shaft b, and actuates the head of the figure through cords q, q attached to cranks on the shaft and connected to an angularly-disposed rock-shaft n, which carries the head. The frame a is formed with a counterweighted rearwardly extending part a provided with a roller c . Small rollers may also be placed under the hands and toes.
