Remote Control Rocks Cradle (Jul, 1939)

Remote Control Rocks Cradle
Rocking a baby’s cradle by remote control is one of the new and unusual uses for the “mystery control” now employed to tune a radio without being near the set (P.S.M., Sept. ’38, p. 78). As pictured below, an electric motor is attached to a cradle rocker, with a metal arm that engages the floor, causing the crib to oscillate back and forth when the motor is switched on by dialing the control box from another room in the house. Other uses for the control include adjusting furnace drafts, and starting coffee percolators before arising from bed.
