    N° 8983 A.D. 1901 Date of Application, 1st May, 1901—Accepted, 5th Oct., 1901 COMPLETE SPECIFICATION. Improvements in Spray Distributing Apparatus. We Johannes Reitz, Student of Medicine, of No. 13 Goethe Strasse, and Ernst Julius Thaler, Doctor of Medicine, of No. 19 Woither Strasse, Loth in the City of Munich, in the Kingdom of Bavaria, in the German Empire, do hereby declare the nature of this invention and in what manner the same is to h he performed, to be particularly described and ascertained in and by the following statement: — The subject of the present invention is a spray distributor by means of which the liquid being sprayed can be distributed to such a distance that even the more distant parts of the room receive the disinfecting- spray, or liquid to be 10 inhaled. For this purpose above the nozzles of the compressed air and suction tubes of a spray producer there is arranged a cap, hood or shield, adapted to catch up any of the compressed air which attempts to spread itself out laterally, whereby such air is caught up and ejected in the direction of the compressed air tube by the 15 following jet of air. For the purpose of increasing this action the mouths of the nozzles may be given a more or less flattened form, so that the current of com¬ pressed air meets an extremely thin jet of liquid, whereby spraying is facilitated. Two constructions of the apparatus are illustrated in the annexed drawing. Fig. 1 is a view showing the end portions of compressed air and suction tubes 20 in conjunction with the cap, here shown in section. Figs. 2, 3 and 4 are end views showing three different forms of nozzle. Fig. 5 is a vertical sectional view of an inhalation apparatus operated by com¬ pressed air. According to the present invention, at the place where the two nozzles of the 25 spray—which may be of any suitable construction—meet, a covering cap, hood or shield o is applied. The nozzles of the suction tube m and compressed air tube p are preferably provided with flattened openings, such as Figs. 2, 3 and 4 shows. These orifices are so located relatively to one another that the compressed air issues directly against a broad band of liquid. 30 Any portion of the compressed air which on leaving the tube p endeavors to escape laterally, is caught up by the cap c within which a whirl is formed, which is then ejected in the direction of the arrow (Fig. 1) by the following current of compressed air issuing from the nozzle. With the apparatus driven by compressed air shown in Fig. 5, the action of 35 the spray distributor nozzle can be still further increased by means of a fan. Into the receptacle «, containing the liquid to be sprayed and the suction tubes m, the compressed air supply pipe c enters from above and is furnished below with a closed funnel or like shaped end d. Projecting from the funnel sides the compressed air nozzles p are provided, meeting the suction tube nozzles 40 at a suitable angle and covered by the cap o. In this apparatus also, the nozzles of the tubes m and p are preferably given a flat or elliptical form for the purpose of increasing the suction effect. On the compressed air pipe c there is mounted a fan i, one or more apertures g being provided in the pipe to enable the compressed air to drive it. 45 Instead of compressed air any other suitable gas under pressure, such as steam, may be employed as distributing agent.
