The Tonjes Aero-Vibrant was a home vibration device that used either compressed air or liquid carbonic acid gas to power the device which would have been delivered to the user's residence—particularly useful if the residence had no electricity (see page 35 in Snow's "Mechanical Vibration and Its Therapeutic Application"). Featured here is a wooden box containing several metal attachments, some with rubber-covered ends.
