ELECTRIC SPRAY- PRODUCING APPARATUS SPECIFICATION forming partof Letters Patent No. 398,327, dated February 19, 1889. I A Application filed November 30, 1838. Serial l'lo. 292,181. (No model.) I

To all whom it may concern.- i

Be it known that I, HILARION ANTOIN E BER- NARD HUGUET DE Vans, a citizen of France, and a resident of Paris, France, have invented certain improvements in Electric Spray-Producing Apparatus, of which the following is a specification. The invention relates to an apparatus for producing spray by electricityj A In order'to make the invention clearly understood, reference will now be made to the accompanying drawing, in which-r- A represents a glass globe having four openings,BB"l3B. Y C G are two glass tubes with reservoirs I) D, the lower ends of which tubes taper ofi and form the capillary tubes cc. These two tubes are curved substantially as shown, so that the .reservoirs D D stand upright, and said tubes fit into the globe A by means of india-rubber. sockets A, which pass through openings 13 B in the globe in such manner that their capillary ends are opposite one to the other and 7 about half an inch or more apart inside the globe A. In each of these tubes there is a very fine silverwire, F 1?, which acts as a conductor for the electricity. These wires do not reach quite as far as the capillary parts of the tubes, as the latter might beobstrncted there.

by. The air is injected through the opening- B by means of a ventilator. The other opening, B, is provided with a funnel-shaped mouth-piece, H, for guiding the liquid after its vaporization by the electric current.

The apparatu is mounted on a support, in which it slides vertically to allow of its adjustment to the height required in order tobe on a level with the respiratory passages of the patient.

The apparatusworks in the following manner: The liquid to be vaporized is introduced into the tubes C C and reservoirs D D The tube 0 is connected with the positive of an electric machine by means of the wire F, and the other tube, 0, is connected with the ground by means of thewire F; Then as soon as the electric machine is started the liquid contained in the two tubes 6 C becomes charged with electricity, and as the electric circuit can only take place by the capillary points 0 c the positive liquid is thrown upon the negative one, dividing the molecules of liquid and producing anextremely fine spray. The air which arrives insidethe globe A by the opening 13 forces the spraythroughthe opening B sothat the person placed before such openingmay breathe the-spray as fast as it is produced. 1 3

What-I claim as my invention, and desire to secure by Letters Patent, is

a In a spray-producing apparatus, a globe, A, provided with openings B B, in which are placed two tubes, 0 C, (terminating in capillarytubes cc and containing wires F F for conducting elect-ricity,) and with openings B" B, the one for receiving a ventilating-tube and the other a mouth-piece, the entire apparatus being fitted into a sliding support, substantially as above described, and represented in the accompanying drawing. i

In testimony whereof I have signed my name to this specification in the presence of two sub scribing witnesses.
