Abstract
139,030. Gillard, C. H. March 18, 1919. Weigh power-storing mechanism.- Talking - machines are driven by a falling weight which is elevated by will by hand or foot. A chain k passing over a cog-wheel e mounted on a spindle c is attached at one end to a lever a. Mounted also on the spindle c is a cogwheel b engaging with a chain h having a weight i at one end and passing over a cogwheel f on the spindle of the phonograph &c. and the cog-wheel b. On depressing the lever a, the cog-wheels e, b are rotated, causing the weight a to be lifted into position for driving the phonograph &c. The lever a returns to its normal position as the weight falls; or the cog-wheel e may have a free-wheel action.
