![Specification Accepted, 8th June, 1889 A.D. 1889, 13th April. N° 6319. COMPLETE SPECIFICATION. A Bronchitis Kettle. Robert James Lee 39 Gunterstone Road West Kensington London Physician Thomas Toogood & James Toogood (trading as William Toogood) Burlington Buildings Heddon Street Regent Street London, Glass Manufacturers do hereby declare the nature of this invention and in what manner the same is to be 5 performed, to be particularly described and ascertained in and by the following statement:— This Invention affords the means of Inhaling Warm Vapour, composed of steam and air combined. This is effected by causing the steam to pass from a small orifice in the Kettle, and play centrally onto and along a tube ; the Air being 10 admitted through orifices in the tube, and induced to pass along it by the force of the steam, as described in Patents 3277/1872 2720/86 5847/86. In addition to the above arrangement for Combining Air and Steam, this Kettle is provided with a feed-tube through which water can be poured directly into the Kettle. This tube as it reaches almost to the bottom of the Kettle, provides against risk of 15 sudden expansion of steam, and thus acts as a Safety Valve. In the accompanying Drawing Fig. 1.
