Chin Plate Stops Mouth Breathing, 1936

An adjustable chin plate has been developed by Oliver Lowry, Meridian, Mississippi in 1936, which, if worn at night while sleeping, eliminates mouth breathing, the principal cause of “whistling” and snoring. The device consists of a padded metal plate that fits the contour of the lower jaw. Adjustable elastic bands insure a satisfactory fit. Two small ribbons that run around the neck are needed when the device is worn by persons having short, stubby chins.

Designed to eliminate mouth breathing while sleeping, this adjustable chin plate builds up the habit of nose breathing to such an extent that its use is soon proved unnecessary.
