Wash Bottle: a Laboratory Wash Bottle with a Slit Valve (Boy Mechanic, 1915)
A wide-mouthed bottle with a three-tube stopper that squirts a steady stream of water for rinsing glassware and washing precipitates. Blow into one tube to pressurise it; a slit rubber valve holds the pressure, and your thumb on a relief tube starts and stops the jet at once.
