Wayback Machine: Multitasking, 1935 Version

In an age where we have electric everything, we forget that things were not always so easy. This Oregon woman thought that pedalling her sewing machine was not an efficient use of her energy, so she "devised a plan whereby her sewing machine pedal could be made to do the work of several things at once.

One length of wood was fastened to the machine pedal, for the driving piston. Another length extending over a frame work fulcrum operated the two lengths of wood which served as connecting rods.

When all was ready, the baby’s cradle was attached to one connecting rod, and the churn to the other. Then as she sewed, the baby rocked, and as the baby rocked, the cream was churned. " ::Modern Mechanix
