Using Electricity to Put the Baby to Sleep
By R. A. Squires
(Second Prize in “New Uses for Electricity” Contest) WHEN our baby arrived, he started life with a severe case of colic, which kept us up at all hours endeavoring to quiet him. We shortly discovered that gently shaking him up and down in his crib would induce him to be perfectly quiet— as long as we kept it up.
This became mighty tiresome, even when my wife and I took turns, and after a few nights we were both worn out. So I proceeded to contrive a mechanical means to shake the baby by mounting a discarded fan motor on a base secured in the lower part of the crib. I ran a belt from the small pulley on the motor to a 6-in. pulley mounted on a short piece of shaft, which was provided with two bearings and a base for attaching.
