Wallingford's improved lantern "is intended especially for use on railways as a signal-lantern." His improvements including the hood, air-holes and their caps "have been found, in practice, to admit of the free escape of the smoke and volatile products of combustion, and not to affect the steadiness of the flame of the lamp, however the lantern may be moved or swung about or be exposed to atmospheric currents." (Patent Number 132,995)
