- Rockin’ Patent: US Patent No. 1,228,532
- Filed: 24 February 1916
- In the name of: Aurion V. Chevers (inventor)
- Title: Musical Instrument Or Vocal Flute
- What’s claimed: “A vocal flute constructed in a single piece from rubber, porcelain or the like in the form of a curved tubular stem with an enlargement at the top adapted to fit against the player’s nostrils to receive a current or air therefrom and with its walls contracted to form a slit-like orifice at the bottom for directing the air across the operator’s lips whereby the vocal cavity acts as a resonator.”
- Why this patent rocks: The instrument described in this patent does not bear much resemblance to earlier instruments, or indeed later ones. According to the patent “[t]the pipe is very easily manipulated to adapt the mouth to act as a variable resonator and the effect produced is exceptionally pleasing and harmonious, very closely simulating the soft notes of a flute or other reed instrument”.
